Dr Vic Peddemorsa co-author from the NSW Department of Primary Industries (Fisheries), said: We discovered that although mid-water fish, especially eastern Australian salmon, were the predominant prey for juvenile white sharks in NSW, stomach contents highlighted that these sharks also feed at or near the seabed.

Mr Grainger said: This evidence matches data we have from tagging white sharks that shows them spending a lot of time many metres below the surface.

The study examined the stomach contents of 40 juvenile white sharks (Carcharodon carcharias) caught in theNSW Shark Meshing Program. The scientists compared this with published data elsewhere in the world, mainly South Africa, to establish a nutritional framework for the species.

Understanding the nutritional goals of these cryptic predators and how these relate to migration patterns will give insights into what drives human-shark conflict and how we can best protect this species, saidDr Gabriel Machovsky-Capuska, an adjunct Senior Research Fellow at the Charles Perkins Centre and a co-author of the study.

Mr Grainger said: White sharks have a varied diet. As well as east Australian salmon, we found evidence of other bony fish including eels, whiting, mullet and wrasses. We found that rays were also an important dietary component, including small bottom-dwelling stingrays and electric rays.

Eagle rays are also hunted, although this can be difficult for the sharks given how fast the rays can swim.

The study found that based on abundance, the sharks diet relied mostly on:

The remainder was unidentified fish or less abundant prey. Mr Grainger said that marine mammals, other sharks and cephalopods (squid and cuttlefish) were eaten less frequently.

The hunting of bigger prey, including other sharks and marine mammals such as dolphin, is not likely to happen until the sharks reach about 2.2 metres in length, Mr Grainger said.

Men’s Health Week: 5 Heart-Healthy Foods to Incorporate Into Your Diet – FemaleFirst.co.uk

Posted: June 15, 2020 at 11:45 am

15 June 2020

As men get older, heart health becomes a major priority. Not only are heart disease and stroke the leading causes of death globally, but experts say that they're more likely to affect men than women too.

Mens Health Week: 5 heart-healthy foods to incorporate into your diet

"The average human heart pumps around 9,000 litres of blood around the body every day. It's a relentless job, and one that needs our support," says Dr. Earim Chaudry, medical director at men's health platform Manual.

"If you're a man, taking care of your heart is doubly important quite literally, as studies have shown men are twice as likely to have a heart attack as women."

Earim says that medical professionals aren't sure what causes this difference. "Some believe it's a result of men being more likely to partake in damaging lifestyle choices, whereas other studies have linked it to protective qualities in oestrogen, meaning women are less exposed until they are post-menopausal."

He adds: "Men also tend to experience heart problems at a younger age than women, making them susceptible for a larger portion of their lives. In the US, for example, the average age for a first heart attack is 65 in men, compared with 72 in women."

The fact stands that if you're a man, it pays to start thinking about heart health sooner rather than later.

Quitting smoking, exercising daily and limiting alcohol are some important things you can do to reduce your risk of heart issues later down the line, but making smart food choices is also key.

As today marks the start of Men's Health Week, we've found a handful of heart-healthy foods to load onto your plate more often.

1. Berries

When it comes to keeping your heart healthy, berries are nutritional powerhouses that all men could benefit from eating more of.

Common varieties like strawberries, blueberries, blackberries and raspberries are packed with anthocyanins a type of flavonoid that's responsible for giving berries, as well as other fruit and veg, their red, purple or blue colour.

Anthocyanins are good for us as they can protect the body against the oxidative stress that can contribute to health problems like heart disease.

Try sprinkling a berry mix onto breakfast porridge or simply wash and plate them up as a healthy afternoon snack.

2. Fatty fish

The essential fatty acids in fish like tuna, salmon and mackerel are vital for maintaining men's heart health, especially as they age. This is because fatty fish is packed with Omega-3, a type unsaturated fatty acid that's long been studied for its anti-inflammatory effects.

In fact, a 2009 study found that eating salmon three times a week, over the course of two months could significantly decrease blood pressure in some adults.

Experts recommend eating at least one portion of oily fish a week to reap the health benefits.

3. Seeds and nuts

Research has found that people who are in danger of a heart attack can cut their risk by including more nuts into their diet.

A 2014 study found that eating walnuts, in particular, can reduce 'bad' LDL cholesterol in the body, which can play a key role in the build up of deposits in your arteries.

Other nutrient-dense nuts to add into salads and snacking include almonds, pistachios and cashews, which are also good sources of dietary fibre and protein.

4. Olive oil

Olive oil is a key staple of the Mediterranean diet, which has been linked with overall good health, including a healthier heart.

The diet incorporates many of the eating habits of countries that border the Mediterranean Sea, with an emphasis on plant-based foods and fish, rather than meat and dairy.

A 2014 study of 7,216 adults also found that those who included olive oil in their diet had a 35% lower risk of developing heart disease, and that the extra-virgin variety gave extra protection.

5. Leafy greens

Leafy greens such as kale and spinach are not only low in calories but are packed with disease-fighting vitamins, minerals and fibre.

Notably, they're a great source of vitamin K, which is vital for proper blood clotting in the body, and could help protect against osteoporosis and inflammatory disease.

Green leafy vegetables are also jam-packed with nitrates, which a 2015 study suggested can reduce blood pressure.

If you don't love the taste of fresh greens in a salad or nourish bowl, you could try whizzing them up in a morning smoothie with some fresh fruit to sweeten the bitter taste.

Keto diet: Expert warns that the low-carb diet could pose surprising health risks – Express

Posted: June 15, 2020 at 11:45 am

The keto diet involves eating as little as 20 grams of carbohydrates a day, which is less than a tenth of the recommended daily intake for women.

But unlike other low-carb diets such as the Atkins and paleo plans which put an emphasis on protein, the keto plan focuses on increasing your fat intake.

With carbs usually being the main source of your bodys energy, a diet that doesnt include enough will lead to the body finding energy elsewhere, by using up stores in the liver and even the muscles.

But doing this on an ongoing basis can lead to ketosis, where the body uses fat and protein to create ketone bodies in the liver; this is often seen as the goal for those following the diet, but its incredibly hard to maintain and not without its side effects.

Though some studies have suggested the keto diet plan can be good for heart health, this could simply be down to the resulting weight loss that can ease some of the strain on the heart.

In fact, Consultant Dietitian Maeve Hanan believes the keto diet could have a negative effect on your health.

The expert, who has written extensively on health for The Food Medic website as well as in her own book, Your No-Nonsense Guide to Eating Well (out this month)has warned of the potential downsides of the keto plan.

As well as worrying that the restrictive diet could lead to an unhealthy relationship with food, Hanan cautioned that the high fat, low-carb nature of the plan could pose a health risk for some people.

DON'T MISS:Weight loss bombshell: Eating these foods can burn fat and tone abs [INSIGHT]How did Adrian Chiles achieve his three stone weight loss? [PICTURES]Coronavirus: Health experts warn to stay away from this diet[COMMENT]

A low intake of wholegrains, a more restricted intake of fruit and vegetables and a higher intake of saturated fat may lead to a higher risk of constipation, bowel cancer and heart disease over time, Maeve explained.

Higher-carb vegetables such as potatoes, squashes and carrots are all out of bounds on the diet plan, which prioritises low-carb options such as broccoli, kale, spinach and mushrooms.

Grains and foods such as pasta and couscous are also off limits in the restrictive plan, as well as beans, peas, lentils and chickpeas.

Even fruit is discouraged, with food such as butter, oils, avocados, chicken, eggs and cheese on the menu instead, in order to up your fat intake.

Maeve also warns that the diet can have a serious effect on your energy levels - which may affect your workouts.

Carbs are the main fuel for our brain and body, and a keto diet can lead to a very low energy intake which could lead to burning muscle for energy and reduced exercise performance, explained Maeve.

Theres even a condition thats known as "keto flu", caused by the restrictive nature of the high fat plan.

The phenomenon can cause symptoms such as tiredness, headaches, diarrhoea, cramps, and weakness.

But Maeve is especially wary of the keto plan when it comes to women who are looking to lose weight, as it could have much wider health implications.

It can contribute to triggering a type of 'starvation mode' called relative energy deficiency in sports (RED-S), Maeve noted, which is most likely to occur in active women who don't consume enough calories - this can lead to issues with fertility, the immune system, bone health and more.

Similarly, there is research emerging that a very low carbohydrate intake (such as the keto diet) may disrupt hormonal function for pre-menopausal women.

Any new diet that involves cutting out food groups or significantly reducing calories should be talked through with a professional first to ensure its right for you, and that it's not going to interfere with any medical conditions or health worries.

Diets have to change for world to experience benefits of increased cycling, new research suggests – Cycling Weekly

Posted: June 15, 2020 at 11:45 am

While many are hailing the coronavirus pandemic for, at least momentarily, getting cars off the road and encouraging people to cycle more in the future, researchers have said that cyclists needing to eat more could also be bad for the environment.

A paper published in the international journal, Scientific Reports, says that more people switching from driving to walking or cycling will lead to an increase in food-production related emissions.

This takes away from the reduction in greenhouse gas emissions caused by so-called passive modes of transport, such as driving.

Therefore, lead researcher Dr. Anja Mizdrak from the University of Otago in New Zealand says people need to be encouraged to take low-carbon dietary options for the necessary extra calories, meaning less meat, dairy and processed food, and more food grown locally and seasonally.

>>> Meet the man cycling 100km a day for 100 days

We have a conundrum but a solvable one. To maximise the benefit on greenhouse gas emissions achieved by increasing active transport, we need to also address dietary patterns. Emissions associated with active transport will be lower if walking and cycling are powered by low-carbon dietary options, Mizdrak said.

The study, the first of its kind to estimate greenhouse gas emissions caused by food intake due to active transport, says the extra food consumption caused by travel would raise greenhouse gas emissions by 0.26 kilograms CO2-equivalents per kilometre for walking and 0.14 kilograms CO2-equivalents per kilometre for cycling, at least in economically developed countries.

To maximise the effect on greenhouse gas emissions achieved by increasing active transport, we need to address dietary patterns too. Emissions associated with active transport will be lower if walking and cycling are powered by low-carbon dietary options, Mizdrak says, urging people to shift away from meat consumption and towards more vegetables, whole grains and fruits.

Given emissions associated with different food groups range widely from 0.02 for vegetables to 5.6 grams CO2-equivalents per kilocalorie for beef and lamb in one global study, consumers switching to foods with lower emissions could reduce overall dietary emissions by up to 80 per cent, adds Dr Cristina Cleghorn.

Of course, health benefits would come around not just from the change in diet added to more people taking up walking and cycling, but more active transport would reduce air pollution and improve the quality of life in urban environments.

In the UK, Greater Manchesters Cycling and Walking Commissioner, the former Olympian Chris Boardman, says the Governments planned 2bn investment in cycling is unprecedented and will help solve short-term issues and will hopefully pave the way for longer-term problems to also be dealt with.

More important than cash, the government has given cycling as a mode of transport a new status, not for ideological reasons but for practical ones, its the most logical solution to short-term problems and then, if we choose, itll help us tackle long-term ones, Boardman told Cycling Weekly.

Why fad diets for weight loss and health dont work, according to science – iNews

Posted: June 15, 2020 at 11:45 am

The coronavirus pandemic has pushed health to the forefront of many peoples minds. And while the best way to avoid COVID-19 is not to catch the virus in the first place, were starting to understand why some people become seriously ill with the disease while others have only mild or no symptoms.

Age and frailty are the most important risk factors for severe COVID-19, but data from our COVID Symptom Study app, used by nearly four million people, has shown that diet-related conditions, such as obesity, heart disease and type 2 diabetes, are significant risk factors for ending up in hospital with the disease.

In the UK, around one in three adults are obese and many more are overweight. In the US, around two in five adults and nearly one in five children are obese. From generalised government nutritional guidelines to Instagram-worthy fad diets, theres no end of advice on how to lose weight. Clearly, it isnt working.

This is a complex problem to unpick. Factors such as sex, ethnicity, socioeconomic status and availability of healthy food all play a part. But on an individual level, we still understand relatively little about how each person should eat to optimise their health and weight.

In search of answers, our research team at Kings College London together with our colleagues at Massachusetts General Hospital, Stanford University and health science company ZOE launched PREDICT, the largest ongoing nutritional study of its kind in the world. Our first results have now been published in Nature Medicine.

PREDICT-1, the first phase of the PREDICT research programme, involved more than 1,000 adults (including hundreds of pairs of twins) who were continuously monitored for two weeks to discover how they respond to different foods.

Participants had an initial set-up day in hospital for detailed blood measurements and testing of responses after eating carefully designed set meals. They then carried out the rest of the study at home, following a schedule of set meals and their own free choice of foods. We measured a wide range of markers of nutritional responses and health from blood glucose, fat, insulin and inflammation levels to exercise, sleep and gut bacteria (microbiome) diversity.

This kind of detailed, ongoing analysis was made possible through the use of wearable technologies. These included continuous blood glucose monitors and digital activity trackers, which meant we could keep track of our participants blood sugar and activity levels 24/7. Simple finger-prick blood tests also allowed us to measure their blood fat levels on a regular basis.

All these measurements added up to millions of datapoints, which needed to be analysed with sophisticated machine learning techniques (a type of artificial intelligence) in order to spot patterns and make predictions.

The first thing we noticed was the wide variation in individual insulin, blood sugar and blood fat responses to the same meals, even for identical twins. For example, one twin might have healthy responses to eating carbohydrates but not fat, while the other twin is the opposite. Straight away, this tells us that we are all unique and that there is no perfect diet or correct way to eat that will work for everyone.

The observation that genetics only plays a minor role in determining how we respond to food also tells us that simple genetic tests claiming to determine the right diet for your genes are ineffective and misleading. Curiously, identical twins only shared around a third of the same gut microbe species, which may help to explain some of the variation in nutritional responses and also points towards an opportunity to improve health and weight by manipulating the microbiome.

We also discovered that the timing of meals affects nutritional responses in a personalised way. The same meal at breakfast caused a different nutritional response in some people when eaten for lunch. But in other people there was no difference, busting the myth that there are correct mealtimes that will work for all.

Another surprise was finding that the composition of meals in terms of calories, fat, carbohydrates, proteins and fibre (macronutrients or macros) also had a highly individualised effect on nutritional responses. Some people handle carbs better than fat, for example, while others have the opposite response. So prescriptive diets based on fixed calorie counts or macronutrient ratios are too simplistic and will not work for everyone.

However, despite the wide variability between participants, each persons own responses to identical meals eaten at the same times on different days were remarkably consistent. This makes it possible to predict how someone might respond to any food based on knowledge of their underlying metabolism.

Intriguingly, we found that the levels of inflammatory molecules in the blood varied by up to tenfold, even in seemingly healthy people, and that a rise in these inflammation markers was linked to having unhealthy responses to fat.

We use the term dietary inflammation to refer to these unhealthy metabolic effects that are triggered after eating. Repeatedly experiencing dietary inflammation brought on by excessive blood sugar and fat responses is linked with an increased risk of conditions such as heart disease, type 2 diabetes, non-alcoholic fatty liver disease and obesity.

On a more positive note, our findings suggest that it might be possible to improve weight management and long-term health by eating in a more personalised way designed to avoid triggering unhealthy inflammatory responses after meals.

When it comes to weight, weve traditionally put a huge emphasis on factors we have no control over, especially genetics. The fact is, while genetics plays a role, many more important factors affect how our metabolism, weight and health. Its time to move away from overly generalised guidelines, fad diets and one-size-fits-all plans and develop more personalised, scientific approaches to nutrition that understand and work together with our bodies, not against them.

Better Love Life, Worse Diet: COVID-19 Outbreak Taking All Types of Tolls on Americans – Study Finds

Posted: June 15, 2020 at 11:45 am

ORANGE, Calif. The novel coronavirus is among the top health concerns for most, if not all of society in 2020. Its effects and implications extend far beyond just physical health, though. COVID-19 has changed virtually all aspects of life for Americans. An extensive new survey reveals how the pandemic is influencing Americans mental health, relationships, and encounters with discrimination or prejudice.

Put together by Chapman University, the survey includes 4,149 adults living in the United States and was conducted at the end of April.

Some of the surveys findings were fairly predictable. For example, 89% of Americans are staying home more often than usual. Moreover, 61% feelmore stressed, 60% more anxious, and 45% are more depressed or hopeless. Many Americans have also seen their healthy habits take a big hit during the pandemic. For example, 37% say theyre eating more because of all that stress, and 41% are eating more junk food specifically. Another 35% admit they arent exercising as much as they did in 2019.

As a nation, we have focused a lot of attention on the physical health risks of COVID-19 and not nearly as much on the mental health, says research leader David Frederick, Ph.D., an associate professor of health psychology at Chapman University, in a release. We know from past research that natural disasters, epidemics and chronic stressors all harm our mental health, but what were experiencing now is radically different than any of those previous experiences. The scale is so much larger.

Upsettingly, the research also reveals that Americans currently working public-facing jobs (grocery store clerks, delivery drivers, restaurant employees) are suffering from poor mental health, anxiety, and loneliness more frequently than other groups right now. This group also reports more bouts of flu-like symptoms.

Over half of Americans (54%) are still very concerned about catching COVID-19. But, 42% say they dont think theyre at a high risk of contracting the coronavirus. Surprisingly, essential workers, healthcare professionals, and police officers all mostly indicate that they arent any more worried about catching the coronavirus than other groups.

Of those surveyed, 2,702 people report being in a long-term romantic relationship. Among that group, 64% say theyve been spending more time with their partner. The average couple during this pandemic has snuggled four times and said I love you six times just over the past week. Some couples are fighting less during lockdown (24%) while others bicker more (25%).

Most people are spending more time with their romantic partner. For some couples, the silver lining is that they are getting to connect with their partner. For others, staying home together allows little stressors to build and blow up which then promotes conflict over existing disagreements, Frederick explains.

As far as sex, 31% agree that lockdown has made them want to have sex with their partner more often. Conversely, 22% say that theyre less interested in sex. Only 19% of participants are actually having more sex right now.

Regarding discriminatory experiences, 32% of surveyed Asian Americans and 38% of surveyed Chinese Americans said theyve dealt with at least one racial incident since the pandemic started. In fact, 25% of Chinese Americans have experienced three or most racist incidents over the past few months. Examples of such incidents include name calling, racial slurs, being told to go back to your country, and even being physically threatened.

African Americans have also had to deal with more racist experiences lately as well; 26% have had at least one negative racial experience and 21% have experienced three or more. No matter the persons race, such incidents are linked to greater feelings of anxiety, depression, loneliness, and hopelessness.

I am troubled by these findings, says Jason Douglas, Ph.D., assistant professor of public health at Chapman and one of the surveys researchers. We need clear and consistent messaging to indicate that viral pandemics do not stem from our ethnocultural minority communities. Rather, residents living in disadvantaged, ethnocultural minority communities are at greater risk for COVID-19 related morbidity and mortality due to longstanding systemic inequities that unfairly limit access to health-protective resources.

These are stressful times, and the survey shows that Americans are utilizing a number of different coping strategies. Most Americans try to take their mind off the pandemic by gardening, exercising, or watching TV (69%). Close to half (48%) are also doing their best to find some meaning and positivity in the midst of this health crisis.

It was nice to see that 36% of Americans have received comfort from a friend or family member. Almost a third (31%) find strength in their religion.

Perhaps one of the surveys most telling findings: Americans who have tried making the best out of this pandemic seem to be faring better from a mental health perspective than their neighbors and peers who have turned to temporary solutions like alcohol.

Those interested in participating in the next leg of the survey can do sohere.

Could the keto diet’s benefits be linked to changes in the gut microbiota? – Gut Microbiota for Health

Posted: June 15, 2020 at 11:45 am

Although the ketogenic (or keto) diet was initially used for treating childhood refractory epilepsy in the 1920s, fasting has been used to treat epilepsy since 500 BC. Later on, variations of the ketogenic diet (such as the Atkins diet) have appeared and its use has extended into adults for purposes other than reducing seizure frequency. They include treating weight loss, metabolic syndrome, certain cancers and psychiatric disorders such as Alzheimers disease.

This high-fat diet resembles the physiological effects of fasting by restricting carbohydrate intake to between 20g and 50g non-fiber carbohydrate per day (an average person in an industrialized country consumes 200g carbohydrate per day). This means replacing grains, fruit, starchy vegetables, legumes and sweets with carb-free or very low-carb foods such as non-starchy vegetables, cheese, avocados, nuts and seeds, eggs, meat, seafood and olive or coconut oil for cooking and dressing. That fat is then turned into ketone bodies in the liver, which can be taken up and used to fuel the bodys cells.

While scientists still struggle with figuring out which mechanisms underlie the keto diets therapeutic benefits, the gut microbiota, epigenetic changes and metabolic reprogramming appear to be involved in the response to diet.

Elaine Hsiao and her colleagues found that the microbiome is required for the anti-seizure effects of the keto diet. When germ-free mice received stool from mice on a keto diet, seizures were reduced, with Akkermansia muciniphila and Parabacteroides being involved in reducing electrical activity in the brain.

This has led scientists to explore whether the keto diet might be worth considering in gastrointestinal disease.

A new study in mice and humans, led by Peter J. Turnbaugh from UC San Francisco, breaks down the effects of the keto diet on the gut microbiome involving a reduction in bifidobacteria levels and pro-inflammatory Th17 immune cells.

First, Ang and colleagues assigned 17 men who were overweight or obese (but non-diabetic) to a control diet for 4 weeks, followed by the keto diet for 4 weeks. Metagenomic sequencing revealed bifidobacteria speciesin particular Bifidobacterium adolescentisdecreased the most on the keto diet.

The authors were also interested in exploring whether these changes were specific to the keto diet or were also observed in the high-fat and high-carbohydrate diet that is known to promote metabolic disease in mice by inducing shifts in the gut microbiome. To this end, Ang and colleagues fed groups of mice with high-fat diets formulated with graded levels of carbohydrates. It turned out that Bifidobacterium levels decreased with increasing carbohydrate restriction, thus highlighting that carbohydrate restriction, rather than high-fat intake, is the main contributor to the keto diets impact on the gut microbiome.

The mucus layer was maintained in the absence of dietary carbohydrates and bile acid metabolism was not affected. This led the authors to test whether ketone bodies themselves could be directly responsible for the progressive decreasing of Bifidobacterium as carbohydrates decreased.

Feeding mice with the high-fat diet and high-carbohydrate diet or the keto diet supplemented with a synthetic ketone esterdeveloped for mimicking ketosis without modifying dietled to increased levels of beta-hydroxybutyrate ketone bodies in the intestinal lumen and less adiposity. That can be explained by the fact that, beyond the liver, intestinal epithelial cells are also a source of ketone bodies.

Interestingly, in vitro experiments in human stool samples and work in rodents showed that ketone bodies selectively inhibited bifidobacterial growth in a dose- and pH-dependent mechanism. While other members of the gut microbiota were also affected to a lesser extent, the selective inhibitory effects of ketone bodies on Bifidobacterium may involve changes at the gut ecosystems ecological level and warrants further research.

Finally, both mono-colonization of germ-free mice with B. adolescentisthe most abundant species in the baseline diet that experienced the most marked decrease after going on the keto diet and human microbiome transplantations into germ-free mice showed that the keto diet mediates the lack of intestinal pro-inflammatory Th17 induction by reducing colonization levels of B. adolescentis. The observed differences in the gut were also detected on Th17 cells in the visceral adipose tissue.

To sum up, this study shows that the keto diet induces changes in the gut microbiome characterized by marked suppression of bifidobacteria coupled with a decrease in intestinal Th17. Said reduction would be worth considering in the context of improving obesity and immune-related diseases with increased Th17 activation.

The results reported here regarding changes in beneficial bifidobacteria, together with gut-related side effects and the nutritional safety of the keto diet due to the exclusion of major food groups, warrants caution on the use of this diet for managing gut symptoms or gastrointestinal disease progression.

Vegan Keto Diet: List of plant-based foods you can eat on the weight loss plan  |  Photo Credit: iStock Images

New Delhi: The Keto diet or the Ketogenic diet is one of the most popular diet plans followed by people for quick weight loss. The diet comprises of low calorie, high-fat food, that help to put the body on the process of ketosis. This helps to burn fat, instead of carbohydrates, for the energy required by the body to perform every day activities, and hence helps in weight loss.

At the same time, a vegan diet has also been linked to many health benefits ranging from weight loss to a healthier heart. So can people who want to stay vegan follow a keto diet? Well, yes, they can. However, most foods that are high in healthy fats are non-vegetarian or animal-based. Here is a list of plant-based foods that people who wish to follow a vegan keto diet can include on their plate to get the best of both worlds.

Roach: Diet and exercise are first prescription to try for prediabetes – LubbockOnline.com

Posted: June 15, 2020 at 11:45 am

DEAR DR. ROACH: My husband is a 50-year-old prediabetic who has recently experienced burning feet. He refuses to think it's his high-carb diet (bread three times a day, chips, ice cream) and instead thinks he just needs some vitamins for foot pain. Could you please explain why and how what he eats affects everything he's experiencing? -- Anon.

ANSWER: Diabetic neuropathy is a condition found in people who have had diabetes for years. It causes different symptoms in different people, but pain (often burning in character) and numbness are most common. The underlying cause is uncertain, but seems to be a combination of factors leading to nerve damage.

Prediabetes, often along with the other components of metabolic syndrome -- including high blood pressure, excess abdominal fat and high cholesterol or triglycerides -- may also bring on a neuropathy with very similar symptoms. Other causes, especially vitamin B12 deficiency, are appropriate to evaluate before determining the condition is most likely due to diabetes or prediabetes.

There are no specific treatments for the neuropathy, although there are medications to ease symptoms. Treatment of the underlying metabolic syndrome is therefore of the utmost importance, and the two most important treatments are diet and exercise. Avoiding simple carbohydrates, such as found in bread and chips, or the sugars in ice cream, is paramount. Regular exercise has an independent effect that adds to the effectiveness of the dietary changes.

Your husband is at risk, and the fact that the symptoms are recent means he should look at this as a wake-up call. Changing his lifestyle dramatically now can lead not only to improvement in symptoms (or at least they won't get worse), but it will also reduce his risk of heart attack and stroke.

There are many places to get help: His doctor, a registered dietitian nutritionist and a diabetes nurse educator all are excellent potential sources of information, but he has to make the decision to start the lifestyle change. Vitamins do not help diabetic neuropathy. If he can start making the changes, I hope he will find, as most people have, that his quality of life and sense of well-being are so much better that he will not want to stop his healthier lifestyle. Medications may be helpful, but the primary treatment is diet and exercise.

DEAR DR. ROACH: My wife smoked for many years and finally quit with the help of nicotine gum that is 4 milligrams each. Since quitting almost 20 years ago, she continues to use about 12 pieces of nicotine gum per day. Does ingesting this much nicotine in this manner put her at risk for developing some type of cancer from the nicotine? -- T.D.

ANSWER: No, nicotine is not carcinogenic, that is to say cancer-causing. In large doses, it is dangerous, but the doses she is taking are not -- at least, for a person used to them. Early signs of nicotine toxicity are excess salivation, nausea and vomiting.

There are many toxic substances in tobacco, some of which are cancer-causing. The tobacco does not need to be burned; chewing tobacco and snuff increase the risk of oral cancer. About half of all people who smoke will die because of smoking-related illness. Even one cigarette a day has significant long-term health risks.

Although it's not ideal that she continues to use nicotine gum (and it's not cheap), there is no doubt that the gum is much, much safer for her than continuing to smoke.

Nearly a billion pounds of beef move through the JBS processing plant in Grand Island, Neb., every year. Except this year: Over the last two months, the company has had to slow production as meatpacking plants around the country have been roiled by coronavirus outbreaks.1Ad Policy

In late March, Nebraska state health officials, fearing such outbreaks, urged Governor Pete Ricketts to temporarily close the plant.2

After Ricketts rebuffed them, stories of missing hand sanitizer and soap, no personal protective gear, and insufficient safety precautions began to leak out of the plant, which as of April had 260 confirmed Covid-19 cases that can be tied back to it. Its difficult to know how many more among its 3,000 workers have been infected since then, because Ricketts has refused to disclose official plant numbers. Across the country, rural areas that contain meatpacking plants with outbreaks of Covid-19 have rates five times those of other rural areas.3

In a daily briefing on April 23, Ricketts dismissed those who thought the largely immigrant meatpacking workers in his state deserved relief by warning, Think about how mad people were when they couldnt get paper products.4

President Donald Trump issued an executive order five days later recognizing meat as a scarce and critical material essential to the national defense, adding that he would ensure a continued supply of protein for Americans under the Defense Production Act of 1950. Rickettsundeterred by the outbreaks in his state and emboldened by the White Houseissued a press release declaring May as Beef Month in Nebraska.5Related Article

Politically, this shows that meat is indispensable, said University of Notre Dame professor Joshua Specht, whose 2019 book Red Meat Republic recounts the history of American beef production. Shortages of meat will personalize the pandemic for everyone, and that is a major political problem when youre trying to say the country is open for business.6

The Covid-19 pandemic has laid bare the fragility of American supply chains, and nothing demonstrates that more acutely than the price spikes, depleted meat aisles, and imposed rationing on a food that weve come to expect in limitless quantities. The brutality of effectively sacrificing human beings to keep those aisles well stocked might be the breaking point in what was already the liveliest debate inside food: the future of beef in the American diet.7Current Issue

Industrial beef is the most polluting, the most carbon-emitting, and the most resource-intensive form of protein. A 2018 study published in the journal Nature recommended that the average US citizen cut beef consumption by 75 percent if we want to keep the global temperature rise to less than 2degrees Celsius above preindustrial levels. In the context of Covid-19, University of Minnesota biologist Rob Wallace has made the connection between global industrial livestock farming and the proliferation of superviruses.8

If youre reading this, youve probably already heard that you should be cutting down on beef. But Trumps and Rickettss decisions show that with beef so embedded in American culture, its not going anywhere without a fight.9

JBS: This Nebraska meatpacking plant processes nearly a billion pounds of beef a yearand is a Covid-19 hot spot for its workers.

Rickettss warning of riots if big government comes for our beef echoes the claim by former Trump adviser Sebastian Gorka that the Green New Deal is a harbinger of authoritarian communism. They want to take away your hamburgers, he bellowed in a speech at the 2019 Conservative Political Action Conference. This is what Stalin dreamt about but never achieved. Gorka made it explicit: To threaten the primacy of meat in the American diet is to threaten a pillar of what it means to be a free American.10

Gorkas ravings about government-mandated burger confiscation sound like some nefarious plot by the same postmodern cultural Marxists decried by the Canadian psychologist Jordan Peterson. In 2018 he revealed on the wildly popular Joe Rogan Experience podcast that he was following an extreme form of the now trendy high-fat, high-protein paleolithic and ketogenic diets: just beef and water. Thanks to the carnivore diet, as he called it, Peterson said hed lost 50 pounds, cured his 30-year gum disease, and seen his lifelong depression cease. Meat, manIm telling you, meat, reads an endorsement of the diet beneath an Instagram photo of him solemnly cutting through a steak.11

Jordan Peterson: Claims he lost 50 pounds, and cured depression and gum disease thanks to a carnivore diet. (CC-BY-SA-2.0)

Peterson first emerged in the public consciousness after protesting a Canadian policy about observing gendered pronouns, which he claimed as evidence of creeping authoritarian rule. He subsequently rode that wave of free-speech martyrdom to a best-selling book, 12 Rules for Life, full of banal self-help infused with social Darwinism. Peterson addresses feelings of real alienation in his audience, but instead of locating the structural sources of their misery, he harks back to an imaginary past when men could be men, before Western civilization became preoccupied with social justice and feminism. In recent years hes become a kind of soothsayer for the mostly young white male demographic that is the subject of worried fascination in the current age of homegrown extremism.12

Its been 30 years since Carol J. Adamss landmark The Sexual Politics of Meat connected the subjugation of animals with the subjugation of women. Studies have shown that men are less likely to embrace eco-friendly practices because we perceive them as feminine; a recent survey of men in the United States found that they were less likely to wear a protective face mask during the pandemic because they viewed them as a sign of weakness.13

Petersons promotion of the carnivore diet was met with scornful incredulity and ridiculed as a self-defeating attempt to own the libs. But defenders of the diet pushed back, reminding us that humans are meant to eat meat and that it provides essential nourishment in the wasteland of the standard American dietdefined by high-fructose corn syrup, refined grains, and industrial seed oils.14

We shouldnt project our politics onto people who are half-dead, trying to get their lives back. Thats what his daughter, Mikhaila Peterson, 28, told me when I asked her about the politics of promoting an all-beef diet in the 21st century. She put her dad on the diet after it helped her with a crippling autoimmune disease and has since rebranded it as her very own Lion Diet.15

You have to reach a certain level of desperation to try it, she admitted. But because of how the media has been portraying Dad, the diet has been unfairly associated with the alt-right. Assigning people a conscious political identity based on their diet would be unwise; Adolf Hitler, famously, was a vegetarian.16

But it would be equally unwise to ignore the embrace of red meat by the far right. Diet books were among the best-selling literature of the 20th century. More than simply offering guidance on which foods to eat and which to avoid, they remain a way to construct grand narratives about who we are. Self-help gets trashed as being an opiate of the masses, said Adrienne Rose Bitar, the author of Diet and the Disease of Civilization. But very few dieters see themselves on an individual quest for bodily perfection. Rather they recognize societal problems like obesity or diabetes and think that theyre going to do their own small part, however impossibly, to create a better world.17

Rogan and alt-right icons like Mike Cernovich and Alex Jones are already established in the dude self-care space, selling skin serums and supplements that might otherwise be considered ladylike. In recent years soy boy has eclipsed cuck as a term to deride the tofu-loving, beta-male archetype. The same return to a past, forgotten glory of men that is central to the appeal of people like Peterson and the nostalgic project of making America great again can also be found among advocates of low-carb regimes like the paleo, keto, and carnivore diets, which stress a return to the natural and traditional foodways of a healthier past.18

Conservative radio host Dennis Pragers faux university PragerU released a video last year titled How the Government Made You Fat, in which the low-carb cardiologist Bret Scher critiques the US Department of Agricultures food pyramid. The antiBig Government message is clear: You are responsible for your own health. Dont rely on the government to take care of you. For the One America News Network correspondent and former Pizzagate enthusiast Jack Posobiec and the far-right commentator Stefan Molyneux, praising meat-heavy, low-carb nutrition is a way to draw a contrast with the crypto-vegetarian piles of birdseed at the public schools their children attend, and Molyneux speculated it could be a communist plot. For others, eating meat is a way to police the boundaries of masculinity. In 2017 the far-right Canadian commentator Faith Goldy asked whether our fridges were the reason men were all of a sudden signing up for womens studies classes. Alex Joness former sidekick Paul Joseph Watson wondered if soy was making Western men more likely to adopt left-wing beliefs. Anthony Johnson regularly hosts paleo nutritionists as part of his premier manosphere gathering, the 21 Convention.19

Even the onetime steak salesman Trump did some nutritional virtue-signaling when it was revealed that he regularly enjoyed two Big Macs at dinner. His former campaign manager Corey Lewandowski quickly clarified to CNN that Trump never ate the bread, which is the important part. The National Cattlemens Beef Associationwhich lobbied for meatpacking plants to remain open during the pandemicdispatched its former senior director of sustainable beef production research, Sara Place, to assure the conservative media host Glenn Beck that methane emissions from cow farts were fake news and that cattle are part of the climate change solution.20

Contemporary right-wing politics survives on a diet of grievance, persecution, and misdirection. In the right-wing mind, feminists and social justice warriors have been joined by the CEOs of Impossible Foods and Beyond Meat, creator of the Beyond Burger (the demand for alternative meat has skyrocketed but has not surpassed the demand for beef during the pandemic), Bill Gates, animal rights activists, Greta Thunberg, and the United Nations Intergovernmental Panel on Climate Change to carry water for the vegan agenda. Modern society has created the least masculine men in history, reads one tweet by the Internets mysterious self-described meat philosopher Carnivore Aurelius. Another proclaims, The Carnivore Diet is the red pill that wakes you up to reality. In these circles, the war on meat is a war on men. Red meat is the red pill.21

Even before the current once-in-a-century public health crisis, it was an anxious time to try to eat healthy. Chronic afflictions like obesity, cancer, heart disease, and diabetescommonly referred to as diseases of civilizationpersist at rates bordering epidemic levels. As populations around the world modernize and adopt something closer to the standard American diet, health outcomes worsen. Our understanding of nutrition hasnt helped.22

The Australian historian Gyorgy Scrinis coined the term nutritionism for a paradigm that allows food corporations to rebrand and remarket ultraprocessed food as health food. In 2007 he identified a nutritional loss of legitimacy that had opened the door to the construction of new nutritional worldviews.23

The paleo diet (the defining diet of the era, according to Bitar) is one example. Drawing on evolutionary biology and the caveman mystique, paleo mimics what was supposedly available to preagricultural humans, with a meat-heavy, grain-free, minimally processed diet. Its what we ate before everyones health went to shit, to quote John Durant, the author of The Paleo Manifesto. The framing is instructive. All diet plans are an attempt to mediate the transition from an agricultural, pastoral lifestyle to an urban, industrialized oneand the distance thats put between us and our food. Existential anxiety over what that change has done to our food and thus ourselves is what unites all diet literature.24

Diet books replicate the 19th century religious form of the jeremiad, Bitar said. They say we are fat, we are ugly, we are sinnersbut together we can lose the weight and regain our understanding of what nature and God can bring. In an essay for the food studies journal Gastronomica, historian Michael Kideckel noted that this understanding of food invariably launders a reactionary view of history.25

In this philosophy of the past, Americans must rediscover a primitive instinct from a time when women did more work within the home, immigrants and indigenous people were even more marginalized, and fewer people saw culture and tradition as the product of specific human decisions, Kideckel wrote. For Durant, our collective health went to shit when women left the kitchen, outsourcing the cooking to corporations. Their traditional role was always an important one and shouldnt be trivialized, he said in a 2017 interview.26

Dieting has been considered a feminine pursuit for so long that when Weight Watchers first marketed to men in 2007, said Tulsa University professor Emily Contois, the tagline was Real men dont diet. But the first diet plans emerged during the mid- to late 19th century, when the ideal man came to be embodied in muscular selves, nations, empires and races, wrote the essayist Pankaj Mishra, who drew parallels between the 19th centurys ideas of manliness and those that contaminate politics and culture across the world in the 21st century.27

Lord Salisbury: Inventor of the eponymous steak. Civilization is harmful to your health. (History Dept. Cornell University)

The earliest diet to go by that name was a meat-heavy, proto-low-carb plan credited to a wealthy Londoner named William Banting, who in 1863 published the pamphlet Letter on Corpulence. It was such a best seller that Bant became a synonym for diet. Dr. James Salisbury, the inventor of the steaks, was another diet pioneer. He experimented with periods of eating only a single food like bread, oatmeal, baked beans, or asparagus before landing onwhat else?beef. It was the food that is most easily digested and that we can subsist on exclusively the longest, wrote Elma Stuart, a follower of Salisburys, in her book What Must I Do to Get Well?28

Diet theorist Mose Velsor: better known as Walt Whitman, inveighed against confections, sweets, salads, things fried in grease.

Salisbury saw his book The Relation of Alimentation and Disease as a way to address the character and capabilities of Western men. Civilization, he wrote, was damaging their physical and moral health, making them more likely to sin and shirk responsibility. He may have been influenced by Mose Velsor, a columnist for the New York Atlas, who in the 1850s worried that city life was producing a generation of soy boys. When Velsors columns were rediscovered and republished in 2016 as Guide to Manly Health and Training, they bore the authors real name: Walt Whitman. Healthy manly virility, he wrote, was being depleted. To foster a more pure-blooded race, Whitman recommended an end to confections, sweets, salads, things fried in grease. Instead he advocated eating fresh meat with as few outside condiments as possible.29

The connection between eating meat and the superiority of Western men was drawn out further in an 1869 essay The Diet of Brain Workers by the neurologist George Miller Beard. What have the natives of South America, the savages of Africa, the stupid Greenlander, the peasantry of Europe, all combined, done for civilization, in comparison with any single beef-eating class of Europe? he wondered. Beard is better known for his theory that the Euro-American brain was so powerful that it could overwork itself into a condition called neurastheniastress or exhaustion. In his 1881 book American Nervousness, he wrote that the affliction that came to be known as Americanitis was caused by the technological advancements of modern civilization. One such advancement was the mental activity of women.30

To cure Americanitis, Beard prescribed that men harden themselves by working on cattle ranches, of course. Theodore Roosevelt would epitomize this transformation in American masculinity. He gained a reputation in the New York Assembly as an effeminate jane-dandy but returned from his time on the frontier with the stoic, aggressive cowboy bravado that would define and plague American masculinity for at least 100 more years.31

As president, Roosevelt popularized the term race suicide to describe the fear that excessively fertile immigrants would outbreed their racial betters. Calling it an unpardonable crime, in a 1914 article, Twisted Eugenics, he castigated women who chose to attend college or use contraception instead of focusing on repopulating the white race. Its not unlike the present-day fears of white genocide or the great replacement that youll find in the tweets of Iowa Representative Steve King or in the white nationalist literature uncovered on Trump senior policy adviser Stephen Millers e-mail server.32

Toughening up on the frontier also meant interaction with Indigenous tribes. Even Salisburys beef remedy was inspired by his observations of Native Americans. There is no reason why we of civilized communities should not live to an even greater age than man does in the wild state, he wrote. But its unlikely that Salisbury ever witnessed the healthy wild state of beef eaters, because cattle are not indigenous to North America.33

Beefs journey to the top of the American diet began with the near extinction of bison and the genocide and forced removal of Indigenous tribes who subsisted on hunting that animal. Cattle ranching becomes central to the dispossession of Native lands and the takeover of western ecosystems, Notre Dames Specht pointed out. Cattle are a tool of, and a justification for, taking that land.34

At the same time that American manhood was redefined as the strong, silent type roaming the western frontier, beef became hypercommodified, readily available and relatively inexpensive for the first time in history. The idea that beef is something you eat all the time is the product of industrial agriculture, its a product of cities, and its a product of the expansion of commodity markets, Specht continued.35

To have a seemingly limitless supply of beef was such a global novelty that it became a badge of Americanness. Immigrants would write home and say, Life in America is hard, but at least I get red meat all the time, Specht said. We can but wonder how the largely immigrant workforce at the JBS plant in Grand Island felt about receiving 10pounds of free ground beef as a coronavirus bonus.36

W here do you go these days to mingle with some of the thought leaders advocating for beef to remain a central part of the American diet? Out west. Last August, over 150 people came together for three days at the University of San Diego student center for the eighth annual Ancestral Health Symposium, a big-tent conference that encompasses paleo, keto, and carnivore people along with anyone else who wants to examine current health challenges through the context of our ancestral heritage, according to the Ancestral Health Societys website. Its a heterogeneous community with plenty of internal debate, but its members share an intense skepticism of the medical, nutritional, and scientific establishment and a celebration of real, natural, traditional food.37

This is the Wild West, man. This is the fringe that the mainstream poaches from, a sturdily built, sandy-haired chiropractor from Los Angeles told me as we looked out at a room of lean, mostly white attendees outfitted for functionalitywicking athletic shirts, yoga pants, five-toed shoes, Xero sandals, blue-light-blocking shades, and slick metal water bottles. He wasnt wrong. The ancestral health community has been on the front lines of reclaiming healthy fat from unfair criticism; despite critiques of the community as overly patriarchal, some feminists have praised ancestral diets as a respite from a culture that equates beauty with thinness, to quote Bitar. If you know about collagen peptides, circadian rhythms, gut microbes, or the dangers of inflammation, these people may have had something to do with it.38

Yet there remains the fact that humans must change our relationship to meat, especially beef, if we are to avoid ecological catastrophe, let alone improve the lives of meatpacking workers or help the animals themselves. But if meat is of essential value to human health, we seem to be in an existential bind, trapped between our perceived nutritional needs and the capacity of our ecosystem and labor force to meet them. In Can Seven Billion Humans Go Paleo? the writer Erica Etelson wondered, If theres not enough animal protein to go around without cooking the planet, who should be first in line? Thats the mostly unasked question at the heart of the meat debate: one of power and ethics, not fat and protein. Thats also the dilemma that many people grapple with (this soycialist writer included) as they eat the occasional burger, steak, or oxtail.39

Ive been called right wing for saying meat is healthy, said Diana Rodgers, a farmer and dietitian. Its very political, but it shouldnt be. Youre either a less-meat environmentalist or you eat a lot of meat and dont care about the environment. Rodgers was in the midst of debunking the EAT-Lancet Commissions planetary health diet, which aims to accommodate the growing global population and planetary limits. The guidelines allow for only one serving of red meat per weeka death sentence to the people in this small auditorium. Rodgers disclosed that the General Mills meat snack company Epic Provisions had paid her way to the conference to help promote her upcoming book and documentary Sacred Cow (the nutritional, environmental and ethical case for better beat, according to her website), which was cowritten by Robb Wolf, the author of the best-selling The Paleo Solution.40

Rodgers argues that beef is the ideal food for the health of the planet because of the potential for holistic range managementan approach to cattle rearing popularized by Zimbabwean rancher Allan Savory and his namesake institute. To oversimplify, cattle are strategically moved around a plot of land in a way that mimics the millions of bison that grazed for thousands of years in North America. This grazing technique restores grasslands and revitalizes soil in a way that allows for substantialmaybe even earth-savinglevels of carbon sequestration. While holistic range management (and the prospect of carbon-neutral burgers) makes intuitive sense and has serious momentum, its also highly polarizing.41

There are credible scientists on either side of the Savory debate, including David Briske and Richard Teague, two professors in the same department at Texas A&M University. Savorys past as an officer in the Rhodesian Army hasnt done him any favors among his critics, who portray him as a delusional iconoclast with no respect for scientific rigor. But to his proponents, which include a growing list of farmers around the world, Savory is a misunderstood sage. The complexity and dynamism of his methods cannot be fully appreciated in summary form.42

If there is a middle ground between the dystopian reality of the beef industry and the unsettling vision of a world without animal agriculture posited by Impossible Foods CEO Pat Brown, holistic range management could be just that. It doesnt seem right that the Norwegian billionaire couple behind EAT-Lancet, Gunhild and Petter Stordalen, are allowed to prescribe diets for the rest of the world while they fly around in a private jet with their own carbon footprint unregulated. I was open to the possibility that the Shake Shack burger I ate the night before was not a personal moral failing but actually a righteous rebellion against the 1 percent. That would make life easier. Then an audience member asked Rodgers if there would be enough land to support a large population on the beef-heavy diet she recommends. She assured him there would be.43

And it could sustain the same population or more as an agrarian-based economy?44

Rodgers was visibly flustered. What I can tell you is that theres too many of us, she replied. Do we want lots of people fed like crap, or do we want healthy people? Our current system is completely failing and producing sick people and killing our environment. So regenerative agriculture is actually the only solution we have moving forward. And, you know, theres too many people.45

Perhaps Rodgers should have chosen an other title for her lecture than Feeding the World a Healthy and Sustainable Dietand other opponents than EAT-Lancet and Impossible Foods. At least their visions attempt to account for the worlds population as it exists. Only 3percent of the beef produced in the United States is designated as grass-fed; even less is raised by Savorys method. Any hypothetical solution in which factory farms transform into holistically managed ranges will ultimately have to confront the multinational agribusiness industry that has been consolidating power for decades. Eating beef is political, whether we want it to be or not. But what was most troubling about Rodgerss answer was her too many people declaration: In those thought experiments, its always the less powerful who count as extra. Its not necessarily right wing to say that meat is healthy, but to quickly revert to claims of overpopulation calls up the darkest strains of both the conservation movement and ancestral health diet literature.46

In 1975 a doctor named Walter Voegtlin self-published his foundational text, The Stone Age Diet, which told a story similar to Rodgerss about the lack of sufficient animal protein to feed a surplus population. Voegtlins solution included limit[ing] reproduction to superior types of individuals and practicing euthanasia of imperfect newborns. Rodgers and others who advise people to eat more meat surely dont endorse that approach, but its worth highlighting how similar their framing is: For some to thrive, others must disappear.47

The Blonde Buttermaker: This former vegetarian liberal has become an animal-fat-obsessed white nationalist.

I kept Rodgers and Voegtlin in mind toward the end of an interview with Tristan Haggard, the proprietor of the popular keto-carnivore YouTube channel Primal Edge Health, which is also the name of his diet brand. A gregarious former vegan, he had spent much of our two-hour Skype call building his case that the plant-based-food movement evolved out of the eugenics movement and is behind a conspiracy to depopulate the world by feminizing men through industrialized vegan kibble. His mantra, Eat meat, make families, is a response to what he sees as the growing cultural degeneracy of modern city life. Instead of being concerned with how you can feed your family or protect your community, men are taught about how cool they might look in a dress, Haggard said. Thats why he fled California to raise his family on a farm in the Andes Mountains in Ecuador. Now he lives like a 21st century primal maneating grass-fed steak, drinking raw milk, and creating content for his subscribers and clients about the dangers of modern soycial engineering.48

I told Haggard I had just heard Rodgers recite the same Malthusian talking points he attributes to vegans. Im glad you brought that up. Its important to read with nuance, he said. While he recognized that overpopulation arguments are usually directed at his neighbors in the Global South, hes appeared on the white nationalist publishing company Arktoss channel to talk up the carnivore diet as part of the fight against globalist hegemony, and hes also rushed to the defense of the Nazis kicked out of the farmers market in Bloomington, Ind. It seems that for Haggard, regardless of your political leanings, if youre on the side of more meat, youre part of the resistance.49

Haggard touts small-scale, local agriculture as a weapon against the globalists, yet he calls climate change a word game and factory farming a straw man argument. His fun-house mirror of inconsistent, repellent, and altogether weird beliefs is not uncommon among prominent followers of Weston Price, the godfather of the ancestral health movement. In 1939, Price published a flawed but compelling ethnography, Nutrition and Physical Degeneration, describing traditional preindustrial diets from the Alps to the Andes. He found several constants, the most important of which are the vitality of animal fat and the degeneration of peoples health after exposure to the Western industrial diet. Today his followers have translated his work into contemporary diet guidelines. Rather than eschew any specific food group, they focus on minimally processed food and old-world farming and food-preservation techniques.50

In the vendor room at the Ancestral Health Symposium, I spoke with a disarmingly friendly volunteer from the Weston A. Price Foundation about the pleasures of bone marrow and roasting vegetables in duck fat and another who was in the midst of shooting a documentary about grass-fed beef. The foundation is best known for Nourishing Traditions, the best-selling cookbook by its founder, Sally Fallon Morell, which popularized Prices work. While the pandemic has shown the importance of local, organic farms, which Prices followers have supported for years, theyre still easily dismissed as cranks because of their opposition to the scientific and medical establishment, as demonstrated by their commitment to unpasteurized dairy.51

Unfortunately, thats not the most controversial claim the foundations leaders have made. In 2018, Morrell wrote on her blog that the Earth stopped warming in the late 1990s and now is in a cooling trend, so we dont have to feel guilty for driving an SUV or eating bacon. The foundation doesnt have an official position on climate change, and when some of her followers protested in the comment section, she replied that the discourse around global warming reminded her of the relentless propaganda against animal fats. Like Haggard, she seems willing to embrace anyone sympathetic to her cause.52

In 2015, Morrell appeared on Red Ice Radio, a Swedish media platform that the Southern Poverty Law Center called one of the most effective white nationalist outlets on the Internet. Before it was banned from YouTube, Red Ice unveiled a cooking and lifestyle show hosted by a neo-Nazi domestic goddess named the Blonde Buttermaker. In an interview on the white nationalist channel NoWhiteGuilt, she spoke of how influential Prices work had been on her journey from former liberal vegetarian to animal-fat-obsessed white nationalist. In the wrong hands, emphasizing ancestral wisdom can be reinterpreted as a permission to embrace ethnonationalism.53

But Prices research does have value if read critically. In Diet and the Disease of Civilization, Bitar analyzes his work using the anthropologist Renato Rosaldos concept of imperialist nostalgia, in which agents of colonialism long for the very forms of life they intentionally altered or destroyed.54

Nowhere was such nostalgia more evident than during the symposium presentation by Paul Saladino, a young, charismatic, and totally shredded carnivore MD. Saladino described the uphill battle in consciousness to convince the world that plant fiber is unnecessary for human consumption. Repeating the ancestral health movements dictum that Indigenous cultures prized fat as a symbol of health and fertility, Saladino encouraged the audience members to swap their kale salads for rib eye and organ meats. He closed by invoking an Andean tribal saying, Wiracocha, which he translated as I wish you a sea of fat.55

Wiracocha was also used to describe Spanish conquistadors, whose white skin was foamy like fat. Its a coincidence that reveals the historical revisionism pervasive in this community. Throughout the weekend there were photographs of healthy, happy, well-fed preindustrial Indigenous groups. But there was no acknowledgment that the rise of cattle ranching depended on eliminating the means of subsistence for Indigenous tribesor that the destruction of foodways has been a deliberate strategy of colonial powers. The slideshows simply showed beautiful people victimized by the forces of nature, whose wisdom was now bestowed on us. A young woman asked Saladino what he would say to someone curious about the carnivore diet. Welcome to the tribe, he replied.56

A sympathetic look at this confused yearning for tribal belonging would take into account what Bitar discovered as the main recurring theme in paleo diet books. Surprisingly, it has little to do with food or nutrition. Our ancestors enjoyed a balanced life of working, playing, relaxing, and worshipping. They felt closeness to one another and everyone had purpose, Bitar said, quoting from Living Paleo for Dummies. Its a human need as basic as food: meaning and connection, especially in a country defined by loneliness and living through a second gilded age of economic inequality.57

This was made even clearer during the last presentation I attended, by a naturopath named Nasha Winters. She informed us that in the past three years, American life expectancy rates declined. The diseases of civilization now have companyopiate addiction, alcoholism, and suicide, the diseases of despair.58

Nowhere is the degeneration of the quality of life in the United States more acute than in the communities surrounding the meatpacking plants that dot rural areas. Americans do need better diets, but we also need to realize that while consumer politics might be transformative for individuals, as public policy, it amounts to window dressing. As University of CaliforniaSanta Cruz professor Julie Guthman noted in her book Weighing In: Obesity, Food Justice, and the Limits of Capitalism, the artificially low price of food has long functioned as a replacement for a living wage and a social safety net, and it comes with serious environmental and public health consequences.59

Over the past 100 years, from Upton Sinclair to Michael Pollan, many Americans have been curious about how the sausage is made. But what most of them really want to know is whether they can keep eating it. The public became concerned with the conditions inside meatpacking plants not out of a concern for workers health but out of worry for what meat shortages might do to their own. Sinclairs famous regret was that he aimed for the publics heart with The Jungle but hit them in the stomach instead. He hoped that exposing the horrifying conditions in meatpacking plants could spark a socialist uprising, but all he got was the Meat Safety Act of 1906.60

The logic that consumer prices are the highest good in terms of social policy, thatcomes from beef, said Joshua Specht. Any movement to reduce meat consumption must address the role that cheap beef has played in providing meaning and nourishment to the masses, or else that ground will be ceded to the Sebastian Gorkas and Donald Trumps of the world.61

The coronavirus pandemic and the looming global ecological crisis are collective problems that individual solutions wont be able to solve. But as Bitar writes, the best way to approach the question of diet is not to call out ignorance but rather to understand myths. When we examine these myths, we can see them truly as the stories we tell ourselves about ourselves, and, perhaps, a story for which we can write a better plot. As difficult as it is to forecast what America will look like after the pandemic, it could be enough of a ground-shifting historical event to spawn new storiesabout why we eat, what we eat, and what we must change to survive.62

Food is so much about who we are and who weve been. To just change that overnight is not really that easy, actually, said Specht. But food isnt just a building block for who we are, its a building block for the kind of society we want to live in. If we can ground our food system in a more rigorous understanding of history, perhaps then we can remake it as a reflection of the society we want to live in. That would be the real red pill, waking us to a new reality.63
