Vitamin B1 may decrease the chances of migraine headaches – Medical News Today

Posted: October 20, 2022 at 2:00 am

Migraine headaches can be painful and difficult to manage.

The specific symptoms and timing are different for each person affected.

Experts are still working to understand why migraine headaches happen and what preventative steps people can take.

A recent study published in Headache: The Journal of Head and Face Pain reports that dietary intake of the B vitamin thiamine may help prevent migraine in some people.

Experts say the information gained from this research indicates a protective factor that may help improve outcomes for people who experience migraine.

Migraine is a neurologic condition that causes severe headaches that are typically localized to one area of the head.

The pain can be intense and people sometimes can experience other symptoms such as nausea or vomiting. Migraine headaches can be related to specific triggers, such as stress or hormonal changes.

Diet is one area that can affect migraine headaches. However, the specifics are something that experts are still working to understand. Specific food triggers or preventative measures can be different for each person.

Dr. Clifford Segil, DO, a neurologist at Providence Saint Johns Health Center in California, noted a few examples of this to Medical News Today:

Dietary triggers are common for migraine. Wines, cheeses, and caffeine can trigger a migraine headache. I ask patients on their first visit with me to keep a headache journal to see if there are any medications that trigger headaches. Caffeine can both cause and help headaches, so it is hard to generalize if something like this causes or helps headaches.

People who experience migraine may work with their doctors and other specialists to identify headache triggers.

As more data emerges about the relationship between diet and migraine headaches, clinical recommendations for treatment may continue to change.

Researchers in the new particular study examined the association between two B vitamins, thiamine (vitamin B1) and riboflavin (vitamin B2), and the experience of severe headaches or migraine.

Researchers looked at data from participants in the National Health and Nutrition Examination Survey (NHANES) from 1999-2004 in their cross-sectional study.

Researchers included more than 13,000 participants in their analysis. Of these participants, 2,745 had experienced either a severe headache or migraine within the past three months. The researchers studied the 24-hour dietary intake of thiamine and riboflavin by looking at data collected from computer-assisted interviews of the participants.

They accounted for several factors, including participants ages, lifestyles, demographics, and comorbidities.

Researchers reported that higher amounts of thiamine in the diet were associated with lower chances of migraine. This was particularly true among female participants. However, the researchers did not find a significant decrease in risk related to riboflavin.

Dr. James Giordano, a professor of neurology and biochemistry at Georgetown University Medical Center in Washington, D.C., who was not involved in the study, noted the following to MNT:

This study provides important data to support that nutritional factors can be influential upon the induction of migraine headache. Of particular note is that this study demonstrated a statistically significant role of thiamine (vitamin B-1) in mitigating migraine. Thiamine has been shown to be particularly important in regulating brain levels of the neurotransmitter serotonin; abnormalities in serotonin function have been directly implicated in the pathophysiology of migraine.

The study did have some limitations.

First, the data relies on self-reporting from participants, which can be inaccurate. For example, when evaluating the incidence of migraine, there is some assumption that participants who reported a severe headache likely experienced a migraine. The 24-hour recall method also has the potential for errors in data collection.

In addition, the interviews did not include questions about all intestinal diseases and researchers did not look into dietary patterns.

Researchers also did not look at the intake of dietary supplements, which could have impacted the intake of thiamine and riboflavin.

Finally, there is the risk of errors based on the analysis techniques used and this type of study cannot prove that lack of thiamine causes migraine.

Overall, the study notes the impact thiamine may have on migraine headaches. It could open the door to further research in this area and later guide specific clinical recommendations.

Giordano noted the following:

Taken together, it may be that thiamine could provide a useful dietary supplement for migraine-suffering individuals who may be mild to moderately magnesium deficient or who have metabolic disturbances of calcium and magnesium metabolism.

He also noted the following areas for continued research:

While research is most certainly interesting and important, additional studies should be conducted to determine more specific roles for thiamine, as well as other vitamin co-factors that may be clinically useful in preventing or lessening migraine.

Were Neanderthals carnivores? A tooth offers new insight into their diets – Down To Earth Magazine

Posted: October 20, 2022 at 2:00 am

"); o.document.close(); setTimeout(function() { window.frames.printArticleFrame.focus(); window.frames.printArticleFrame.print(); document.body.removeChild(a); }, 1000); } jQuery(document).bind("keyup keydown", function(e) { if ((e.ctrlKey || e.metaKey) && (e.key == "p" || e.charCode == 16 || e.charCode == 112 || e.keyCode == 80)) { e.preventDefault(); printArticle(); } });

New research suggests that the closest extinct relatives of humans, the Neanderthals, may have been carnivores. The diets ofHomo neanderthalensishave been a topic of debate for a long time.

Neanderthals showed high levels of carnivory, lending more weight to the theory suggesting thatour extinct relatives may have been primarily meat eaters, according to a new study.

Researchers in the new study examined a molar belonging to a Neanderthal individual found in Iberia using a less explored technique. The individual was found at the Gabasa site in Spain.

Analysis showed that the individual did not consume the blood of their prey, the study published in journalProceedings of the National Academy of Scienceshighlighted. However, the individual ate the bone marrow of their prey.

Some previous studies examining the dental tartar of remains from the Iberian Peninsula show that Neanderthals were majorly herbivores.

Other studies conducted outside the Iberian Peninsula, according to the researchers, indicate that our extinct relatives feasted on a meat-heavy diet.

Another study recorded evidence of cannibalism at two Iberian sites. But this may be due to nutritional stress.

"I wanted to see how different their diets were from those of modern humans and how to explain it," Klevia Jaouen, the lead author from the French National Centre for Scientific Research (CNRS), toldDown To Earth.

This is important because the disappearance of this species is frequently attributed to their subsistence strategy orhow they sourced food and other raw materials from their environment.

Previous techniques analysed nitrogen isotopes in the bone collagen. However, this method is suitable in temperate environments, the experts stated. They are less likely to work on samples over 50,000 years old as collagen degrades over time depending on the environmental conditions, the paper said.

But the Gabasa site in Spain could not meet the required conditions. So Jaouen and her colleagues decided to use zinc isotopes in the molar sample. Their analysis showed that this individual switched to an adult diet from the mothers milk before age two.

The Neandertal individual from Gabasa, according to the study, showed a zinc isotope signature of a top-level carnivore.

The researchers ruled out cannibalism due to the absence of cut marks on hominin (a group consisting of modern humans, extinct human species and all our immediate ancestors) and carnivore bones.

A low zinc value suggests that the species ate muscle and liver from deer and rabbits, leaving out their blood and bones.

Read more:Neanderthals died out 40,000 years ago, but there has never been more of their DNA on Earth

Other carnivores like red foxes, wolves and lynxes have been known to gnaw or partially digest bones. They also consume blood, said the study. These trends suggest that the Gabasa individual might have been on a diet distinct from other carnivores, the researchers wrote in the study.

Jaouen could not document any plant consumption based on the zinc-isotope analysis. But if they ate fruits from time to time, we could not detect it because fruits do not contain a lot of zinc, the expert explained.

Plant consumption was probably not a substantial part of their diets, she added. The researchers are also unsure whether Neanderthals showed regional differences in food consumption.

We would like to confirm these conclusions by analysing more specimens. We are working on it, she said.

We are a voice to you; you have been a support to us. Together we build journalism that is independent, credible and fearless. You can further help us by making a donation. This will mean a lot for our ability to bring you news, perspectives and analysis from the ground so that we can make change together.

Leroy Creasy, touter of red wine’s health benefits, dies at 84 | Cornell Chronicle – Cornell Chronicle

Posted: October 20, 2022 at 2:00 am

Leroy Creasy 60, M.S. 61, whose research on the health benefits of grapes and red wine has spurred decades of public interest and scientific inquiry, died June 15 in Aurora, New York. He was 84.

Creasy, a professor emeritus of pomology in what is now the Horticulture Section of the School of Integrative Plant Science in the College of Agriculture and Life Sciences, was best-known for his work on resveratrol, a natural compound found most abundantly in red and purple grapes. In the early 1990s, Creasy identified resveratrol in red wine and posited that this heart-healthy, cancer-fighting compound might explain the French paradox why Mediterranean populations that had relatively high smoking rates, high-fat diets and higher wine consumption also suffer fewer heart attacks and lived longer than populations with ostensibly healthier habits.

Resveratrol is a type of secondary metabolite a compound created by a plant to ward off insects or fight disease. More than 70 species of plants produce resveratrol, including peanuts, cocoa beans and blueberries, but it occurs in highest amounts in the skin of red and purple grapes. Grapes produce resveratrol in response to disease pressure, especially from mildew a common plague of grape growers in New York and Creasy found that New York-grown grapes were higher in this beneficial compound than grapes grown in sunnier climates. Later research showed that resveratrol production can also be triggered by UV radiation.

Creasys discoveries drew tremendous public attention, including features on 60 Minutes and in the New York Times, said Marvin Pritts, professor in the School of Integrative Plant Science, Horticulture Section. They also drew controversy, as some public health officials and other researchers warned against the negative effects of increased alcohol consumption. Proving or disproving a connection between red wine and heart health will always be difficult, because such studies rely on correlational observations, Pritts said.

Resveratrol was getting loads of press; Les phone was ringing a lot, Pritts said. Resveratrol is definitely beneficial for health, but the jury is still out on whether wine is good for you.

Even so, Creasys findings boosted the fortunes of wineries across the country, especially in New York, as people sought out red wines, said Glen Creasy 88, Leroy Creasys son and a viticulturist and co-owner of Terre des 2 Sources, a vineyard and winery in the south of France.

His work created some controversy, but it also certainly generated a lot of other research into the healthful and not-so-healthful components of wine, said Glen Creasy, who worked for 19 years as a lecturer in viticulture in New Zealand before moving to France. He made a really significant impact, from both a scientific and a public perspective.

Leroy Creasy was a member and past president of the Phytochemical Society, the American Society for Horticultural Science and the Scientific Advisory Board of the California Table Grape Commission.

After his retirement from Cornell in 1998, Creasy and his wife, Min 60, bought a 160-acre farm in Aurora, where they grew table grapes (grapes meant to be eaten fresh, rather than processed into jam, juice or wine) and published together. Creasy continued experimenting in his vineyard and established procedures to increase resveratrol levels in his grapes, Glen Creasy said. Father and son also co-wrote two editions of the book, Grapes, a crop production handbook published by the Centre for Agriculture and Bioscience International.

Leroy Creasy was born Feb. 21, 1938, and grew up in the outskirts of New York City. He earned his Ph.D. from the University of California, Davis, then spent one year as a National Science Foundation fellow at the University of Cambridge, England. He joined the Cornell faculty in 1965. Creasy is survived by Min, his wife of 62 years; sons James 86 and Glen; and four grandchildren.

Krisy Gashler is a writer for the College of Agriculture and Life Sciences.

NMU-Funded Bear Study Results Published | Northern Today – Northern Today

Posted: October 20, 2022 at 2:00 am

Northern Michigan University researchers were involved in a recent collaborative study of the gut microbiome of Alaskan brown bears, which showsthat the microbial life in bears' guts allows them to achieve comparable size and fat stores while eating widely different diets.

Fecal samples were collected from 51 adult brown bears in three National Parks and Preserves: Katmai; Lake Clark; and Gates of the Arctic. Previous researchdemonstrated that theirdiets vary by location.

Bearsat Lake Clark generally eat a lot of berries, salmon and mammals, such as moose. Bears at Gates of the Arctic tend to eat seasonal vegetation and mammals, but have less access to fish. And bears on the coast of Katmai have the most diverse nutritional landscape, including a variety of vegetation, fish, and a wide range of marine species.

The fact that these populations have distinct diets is valuable, because it allows us to understand the role that the gut microbiome plays in helping bears extract nutrition from very different food sources, says Sarah Trujillo, corresponding author of the study and a former graduate student at NMU. We found that bears benefit from having diverse dietary niches, and the gut microbiome does play a role in extracting nutrition from those diets. Ultimately, that means that the bears in these parks were able to achieve very similar body conditions, despite eating very different things.

And because the parks are protected, well-conserved environments, this study can serve as a baseline for future research, says Diana Lafferty, co-author of the study and an assistant professor of biology at NMU. For example, researchers will be able to compare the gut microbiomes of bears in more disturbed systems such as areas where bears have more access to garbage and human foods to the data from this study.

Erin McKenney,co-author of the study and an assistant professor of applied ecology at North Carolina State University, said the workfunded by NMUsheds light on the role of the gut microbiome in supporting health in wild omnivores.

"We think of bears as having simple digestive tracts, so it's easy to slip into thinking that they therefore have simple gut microbiomes, McKenney added. "But this study shows there can be tremendous diversity in the gut microbiomes between individual bears, and that this variation can be very important to the physical condition of these animals.

For example, the amount of fat that bears are able to store is absolutely critical to the health of wild populations, says Grant Hilderbrand, co-author of the study and associate regional director for resources for the National Park Service in Alaska. If female bears are able to reach levels where 19-20% of their body mass in the autumn is fat, they'll reproduce. And knowing that they can take different dietary paths to reach those fat levels is a valuable insight.

"Knowing what bears are eating, and that diverse diets can all be used to reach similar body conditions, can help us detectemerging challenges for these animals. It can also help us understand how many bears these ecosystems are capable of supporting, even as those ecosystems change.

The study, Correlating gut microbial membership to brown bear health metrics, is published in the open-access journalScientific Reports. The paper was co-authored by Kyle Joly and Buck Mangipane of the National Park Service; Lindsey Mangipane, David Gustine and Joy Erlenbach of the U.S. Fish and Wildlife Service; and Matthew Rogers of the National Marine Fisheries Service.

To address iron deficiency in Africa, researcher develops fortified version of popular hibiscus drink – University of Toronto

Posted: October 20, 2022 at 2:00 am

Folake Oyewoles doctoral thesis project was inspired, in part, by the potential health benefits of arefreshing drink: Zobo, a hibiscus-based beverage that is popular in Oyewoles home country of Nigeria.

People consume Zobo as a cold beverage in Nigeriabecause its refreshing and claimed to provide many health benefits, says Oyewole, a chemical engineering PhD candidate in the University of Torontos Faculty of Applied Science & Engineering.

I wanted to ascertain whether these drinks actually add micronutrients to the body, and if they didnt, whether we could make it so that they did in a way that could be absorbed and used by the body.

Supported by theSchlumberger FoundationsFaculty for the Future Fellowship,Oyewole says she has alwaysbeen interested in value-added processing of food and beverages, particularly ones with ingredients sourced from Nigeria. Her passion led her to join the lab ofLevente Diosady, a professor emeritus in the department of chemical engineering and applied chemistry, who specializes in food engineering.

Diosadys lab group is developing a new way to fortify beverages like Zobo with iron a mineral that manyacross Sub-Saharan Africa, particularly women, are lacking in sufficient quantities. The new iron-fortified beverage will make use of hibiscus sourced from Nigeria.

Iron deficiency is the leading cause of anemia world-wide.Forwomen of reproductive age, iron-deficiency anemia can lead to poor health outcomes and pregnancy complications such as preeclampsia, postpartum infection and low infant birth weight. In Nigeria alone, theWorld Health Organization estimatesthat 55 per cent of women of reproductive age have anemia.

Thats why fortifying foods with iron has been a key focus ofDiosadys Food Engineering Laboratory for years. Past projects have included adouble-fortified salt,which in trials of60 million consumersin India was found to significantly improve the iron status of women.

Folakes work continues our goal of improving the iron status of women and infants by providing a natural fortification of a locally produced beverage, says Diosady. If properly marketed, this fortified beverage could improve the iron status of women of reproductive age, without medical infrastructure or any change in dietary habits.

Creating an iron-fortified beverage isnt as simple as adding some mineral salts into the recipe. Oyewoles new product needs to account for the unique challenges associated with the dietary habits of the population she is working with.

The human body absorbs iron from well-rounded diets that include meats, eggs and leafy greens, as well as foods fortified with iron. But in Sub-Saharan Africa, many households are limited to eating mostly plant-based diets with very little varietydue to the prohibitive cost of iron-rich meat.

On top of this, many plants have an abundance of polyphenols. This family of naturally occurring molecules which includes flavonoids, phenolic acids and resveratrol has many disease-fighting properties,including inhibiting cancerous tumor generation and growth. But polyphenols also bind to iron in a way that prevents the latter from being absorbed by the body.

Oyewoles fortified hibiscus beverage needs to address both the inadequate dietary iron intake, as well as the reduced iron uptake that results from a diet rich in polyphenols.

The most at-risk groups who are dependent on plant-based diets often dont realize that they cant absorb iron efficiently, says Oyewole.

This is why when addressing micronutrient deficiencies at the population level through food fortification,its really important to choose the right food vehicle. We want to reach this population with something they are familiar with, something they already produce and consume widely so we can predict the consumption pattern of the population.

Its also important to choose a foodthat can be centrally processed so that the iron dosage can be controlled, adds Oyewole. And the fortification process shouldnt be so expensive that it significantly raisesthe cost of the food.

Oyewole began her research by analyzing the iron content of the hibiscus calyces the part of the plant that protects the bud and supports blooming petals used to make Zobo. While Oyewole found it to be relatively rich in iron, 70 per centis lost during the extraction process since most of the iron is bound to the residue that is not transferred into the beverage. She also found that the calyces contain 25 times more polyphenols than they do iron.

Oyewole then fortified the beverage by adding ferrous sulphate heptahydrate, an iron salt, to top up the iron already present. Her goal was to provide a total of six milligrams of iron per 250 milligrams 30 per cent of the target recommended daily allowance for women of childbearing age.

To prevent the iron-polyphenol interaction, she introduced disodium EDTAinto the beverage. Previous results in the lab suggest that this substance can release iron from the iron-polyphenol complex and make it available to be absorbed by the body.

Oyewole is also working on ensuring that her iron fortification method will preserve the organoleptic properties of the original beverage that is, the flavour, texture and colour.

Iron has a very distinct, metallic taste, so another layer of my work is to make sure that the sensory properties of the fortified beverage the taste, mouthfeel, aftertaste and colour matches the original, she says. Otherwise, we risk formulating a fortified beverage that will be rejected by the consumer.

Once this is achieved, the next step will be to form partnerships with stakeholders, including government agencies in Sub-Saharan Africa, to make the fortified beverage accessible for the target population.

Working in the Food Engineering Laboratory has been a great privilege, Oyewole says. From an outside perspective, it may seem like we just add micronutrients to food and thats it. But there are a lot of complexities with the materials we are dealing with, including preventing unwanted interactions between the food vehicle and the added micronutrients.

Our research outcome has the potential for significant impact globally. Invariably it challenges poverty, increases productivity and promotes health it is all intertwined.

To combat food insecurity and build nutrition equity iHeartMedia and Anthem Blue Cross partner with Common Threads to launch Food as Medicine classes…

Posted: October 20, 2022 at 2:00 am

LOS ANGELES--(BUSINESS WIRE)--On the heels of the White House Conference on Hunger Nutrition, and Health, iHeartIMPACT and Anthem Blue Cross are continuing their multi-year national partnership to combat food insecurity and improve health in marginalized communities by partnering with non-profit Common Threads to provide hands-on culinary programming focused on food as medicine in under-resourced schools in Los Angeles.

To support their ongoing commitment to the Los Angeles community, iHeartMedia, Anthem Blue Cross, and Common Threads will launch culturally responsive hands-on food as medicine programs in three LAUSD schools including Manual Arts High School, Baldwin Hills Elementary, and Coliseum Street Elementary to ensure students and families not only have access to nutritious food but also build the skills to prepare healthy meals that can help combat obesity and food-related chronic conditions or diseases. To mark the occasion, the partners hosted a produce distribution event with Chicas Verdes and Food Forward providing 250 families with bags of groceries of fresh produce. Joined by Los Angeles Sparks, students were able to participate in a live cooking demonstration from Common Thread instructors and Anthem Blue Cross volunteers on how to create a healthy meal from the food provided.

Last year, iHeartMedia and Anthem Blue Cross helped fully renovate and expand the student-run garden program at Manual Arts High School, providing students with an opportunity to learn how to grow fresh produce. Now, we are doubling down on our ongoing commitment to combat food insecurity in our communities across Los Angeles by adding nutrition education, focused on food as medicine, to our program, said Kevin LeGrett, President of iHeartMedia Sports. Its not enough to just distribute nutritious food, we want to make sure students and their families are equipped with the skills to make healthy meals and empowered to make informed food decisions that ultimately can improve their physical and mental health outcomes.

One of every five deaths across the globe is attributable to a suboptimal diet. Chronic diseases and conditions such as obesity, heart disease, hypertension, high blood pressure, and diabetes are key drivers of total U.S. healthcare costs. However, people with diets rich in vegetables and fruit have a significantly lower risk of obesity, heart disease, stroke, diabetes, and certain types of cancer. Research also suggests that deficiencies in certain nutrients may contribute to or exacerbate conditions such as depression, bipolar disorder, schizophrenia, and obsessive-compulsive disorder (OCD). Addressing the growing prevalence of diet-related diseases in the United States depends on preventative efforts at the individual, community, and public health levels.

"We are thrilled to continue working with our community partners to address health-related social needs and promote health equity through access to nutritious foods here in Los Angeles, said Dr. David Pryor, Regional Vice President and Medical Director at Anthem Blue Cross. We know that lowering barriers and making it easier for individuals to access everyday items, like nutritious food, are some of the best ways to help people live healthier. We are doing that here today by helping build hands-on nutrition knowledge for students and families, which will help open paths towards health equity for future generations."

Students with a healthy balanced diet are more likely to have stronger immune systems, lower risk of diabetes and heart disease, and live longer. A healthy diet is crucial for optimal learning because it can boost brain function and improve mood. The new partnership with Common Threads includes year-round hands-on nutrition education curriculum for students and their families that rolls out in late October. Elements of the curriculum include focusing on affordable and healthy ingredients, embedding culturally relevant content and teaching practices, increasing vegetable and fruit intake, emphasizing whole grains and lean protein, and reducing sugar intake and ultimately increasing knowledge and skill for cooking at home to utilize healthy foods that have been demonstrated to improve physical and mental health outcomes.

Food is an essential part of our lives and the nutrition we need to thrive comes from good food choices. Providing hands-on training as part of the class curriculum is one of the most powerful and effective ways to make an impact early in life which can translate to improved physical and mental health outcomes, said Common Threads Executive Director Linda Novick OKeefe. Often one minor adjustment to a traditional recipe can take a meal high in fat with empty calories to a deliciously nutritious meal that will fuel and nourish your body. Our mission is to teach children and their families easy and affordable ways to shop for and prepare their favorite meals, encouraging behavioral changes that last a lifetime.

About iHeartIMPACT & Anthem Blue Cross Partnership

iHeartIMPACT is a division of iHeartMedia that focuses on aligning brands with nonprofit organizations. Anthem Blue Cross and its affiliated companies are working with iHeartIMPACT to support a series of nutrition education programs in a total of six schools across Los Angeles, New York, Atlanta and Indianapolis. This partnership with national health and wellness organization, Common Threads, is an extension of the companies' multi-year commitment to addressing food insecurity and whole-health for communities across the country.

About Common Threads

Common Threads is a national nonprofit that provides children and families with cooking and nutrition education, striving to equip communities with the necessary information to make affordable, nutritious, and appealing food choices wherever they live, work, learn, and play. By December 31, 2029 they committed to distributing 1,447,000 nutritious meals and snacks, and 1,228,500 hours of nutrition education. They aim to tackle the critical issues of limited access to healthy foods and nutrition-related health disparities in communities by reaching over 260,000 participants in low-income households across the United States, to offer culturally relevant nutrition education and hands-on cooking skills at community centers including schools, community organizations, and healthcare providers.

How does the memory of bumblebees work? – Earth.com

Posted: October 20, 2022 at 2:00 am

A new study led by the Queen Mary University of London (QMUL) has found that bumblebees do not seem able to keep memories for how sweet a particular flower was, but instead only remember if it was sweeter than other flowers.

The researchers first trained bumblebees on two flowers, making them learn that one flower was sweeter than the other. Later on, they also learned that a third flower was sweeter than a fourth one. Then, the insects were given the choice between two of the flowers they had not seen together before, such as the first and the third, or the second and the third.

During the experiments, the bumblebees preferences indicated that they could only retain very basic ranking memories for the flowers for an extended period of time. While they could remember that a flower had been better or worse during the training phase, they did not seem capable of remembering for more than a few minutes how sweet or rewarding the flowers were on their own, or even how much sweeter they were compared to other flowers.

While humans and other animals, such as starlings, are able to keep memories for both absolute information (e.g. how sweet something is) and comparisons (if something is sweeter than something else), bumblebees seem unable to memorize absolute information.

Our results reveal an intriguing divergent mechanism for how bumblebees retain and use information about options, compared to humans and birds, said study co-lead author Yonghe Zhou, a doctoral student in Biological and Behavioral Sciences at QMUL.

It may be that the different strategies used by bumblebees and humans may have evolved because of their different diets, added study senior author Fei Peng, a psychologist at Southern Medical University in China. Maybe because bumblebees evolved to mostly only eat flower nectar, they never needed to remember the details and could survive and thrive simply using simple comparisons.

Despite what may seem to be a poor memory strategy, bumblebees do very well in finding the most profitable flowers. Its fascinating to consider how different animals, in their own ecological niche, can be similarly successful using such different strategies, Yonghe concluded.

The study is published in the journal eLife.

Crash dieting for a prolonged period is unhealthy and should not be done without professional guidance. This brings us to the next topic should teenagers crash diet? Since the crash diet gives quick results, many teenagers want to follow it. But should they? Find out below.

No, teenagers should not crash diet. The ages of 13 to 19 are part of the growing phase. Going on crash diets might stunt your growth and affect your mental health. If you do need to lose weight, seek the help of a professional.

Talk to a registered dietitian and get a customized diet chart. You must also be physically active and aim to be fit and strong. Also, remember, you dont have to fit into any size to feel beautiful and worthy. Be healthy and happy, and pursue your dreams.

Heres the takeaway message.

Crash diets are unsustainable and unhealthy. The weight that you lose is mostly water weight. Moreover, most people tend to misuse these diets, which causes health issues. We do not recommend going on an unsupervised crash diet. You must consult your doctor before trying out our sample 7-day crash diet plan.

Crash diets are the quickest way to lose some pounds quickly, but they can turn out to be extremely dangerous if misused. They have to be treated as short-term weight loss options. Following these diets, which involve taking less than 800 calories a day, for more than a week is not advisable. Your body may get deficient on the nutrient front and lead to adverse effects like weak immunity, nausea, muscle loss, etc. Consult a doctor if you are a new mother, obese, old, or on antidepressants. These diets are a strict no-no for teenagers as they may impact their physical and mental growth. If you have a larger time window (like a month) for a special occasion, opting for the Mediterranean diet is advisable.

Losing 20 pounds in a week is not possible unless you go for weight loss surgery. In a week, you can lose 1-2 pounds if you follow a low-calorie diet and workout. If you follow a 7-day crash diet, you may lose up to 10 pounds in a week.

What should I stop eating to lose weight?

Stop eating sugary foods (soda, sugar-free foods, candy, cake, pastry, doughnut, cookies, macaroon, and sweets), foods loaded with trans fats (like cookies, biscuits, chips, fries, fried chicken, and frozen pizza), high sodium foods (like soda, fries, bottled sauces, ketchup, ready-to-eat foods, frozen foods, and pickles), refined flour, white rice, and alcohol.

Whats wrong with crash dieting (or controlled anorexia)?

Anorexia is an eating disorder. A crash diet will not go wrong until you do not follow the dietitians or doctors instructions. Many of us crash diet by starving ourselves to lose more weight in a short span of time. Thats not the way to go about it. Consume small portions of all kinds of healthy food.

How does a crash diet affect health and metabolism?

Crash dieting for a prolonged period will affect your bodys normal activities. As it is a low-calorie diet, your body will be deprived of the nutrition that is required for it to function properly. You will start feeling weak and end up weakening your bodys immune system. As you starve for longer hours, the body starts accumulating whatever food it gets. This reduces the metabolic rate and leads to a host of eating disorders. Also, this can lead to weight gain instead of weight loss.

Counting calories: Get back to weight-loss basics – Mayo Clinic

Counting calories: Get back to weight-loss basics

Weight control really boils down to one thing calories. See what steps you can take to win the calorie battle.

Even with all the diet plans out there, weight management still comes down to the calories you take in versus those you burn off during activity.

Popular fad diets may promise you that not eating carbohydrates (carbs) or eating a pile of grapefruit is the secret to weight loss. But it really comes down to eating fewer calories than your body is using if you want to lose weight.

Calories are the energy in food. Your body has a constant demand for energy and uses the calories from food to keep working. Energy from calories fuels your every action, from fidgeting to marathon running.

Carbohydrates, fats and proteins are the types of nutrients that have calories and are the main energy sources for your body. No matter where they come from, the calories you eat are either converted to physical energy or stored within your body as fat.

These stored calories will stay in your body as fat unless you use them up. You can do this by cutting how many calories you take in so that your body must draw on reserves for energy. Or you can add more physical activity so that you burn more calories.

Your weight is a balancing act, but the equation is simple. If you eat more calories than you burn, you gain weight. And if you eat fewer calories and burn more calories through physical activity, you lose weight.

In the past, research found about 3,500 calories of energy equaled about 1 pound (0.45 kilogram) of fat. So researchers thought burning or cutting 500 calories a day led to losing 1 pound a week. But this isn't true for everyone.

In general, if you cut about 500 calories a day from your usual diet, you may lose about to 1 pound a week. But this can vary depending on your body, how much weight you want to lose, your gender and activity level.

It sounds simple. But it's more difficult because when you lose weight, you usually lose a mix of fat, lean tissue and water. Also, because of changes that occur in the body as a cause of weight loss, you may need to decrease calories more to keep losing weight.

Cutting calories needs to include change, but it doesn't have to be hard. These changes can have a big impact on the number of calories you take in:

Skipping one or two high-calorie items is a good place to start when cutting calories. For example, you could skip your morning latte, soda at lunch or that evening bowl of ice cream.

Think about what you eat and drink each day and find items you could cut out. If you think that skipping your treat will leave you with a craving, swap it with a low-calorie choice.

Simple swaps can make a big difference when it comes to cutting calories. For example, you can save 60 calories a glass by drinking fat-free milk instead of whole milk. Instead of having a second slice of pizza, reach for some fresh fruit. Or snack on air-popped popcorn instead of chips. Eat more fruits and vegetables, which have many nutrients and are high in fiber. And they'll fill you up more than high-fat choices.

The sizes of your portions affect how many calories you're getting. Twice the amount of food can sometimes mean twice the number of calories. But some foods with fewer calories, such as many fruits and vegetables, can be eaten in larger portions.

It's common to guess that you eat less than you actually do, such as if you're dining out. Paying attention to your portions is a good way to control calories.

Try these tips to control portion sizes and cut calories:

Replacing high-calorie foods with lower calorie choices and cutting your portion sizes can help you cut calories and improve weight control. For a successful and lasting weight management plan, you also need to increase your physical activity. Combining regular activity and healthy eating will best help you get to and maintain a healthy weight.

5 Best Vegetables for Weight Loss, Say Dietitians – Eat This Not That

Posted: October 20, 2022 at 1:59 am

You can't go wrong with eating veggies. In fact, according to the Harvard School of Public Health, a diet that contains plenty of vegetables on a regular basis can help you prevent heart disease, manage blood pressure, improve your digestive health, and help you manage your blood sugar levels.

Along with these health benefits, vegetables can help you meet your weight loss goals as well. One study published in the European Journal of Clinical Nutrition found that increasing your consumption of veggies could contribute to increased weight loss.

To learn more, we asked a couple of expert dietitians to weigh in on the best vegetables to eat for weight loss. And for more healthy weight loss tips, check out 5 Best Breakfast Habits for Belly Fat Loss.

Broccoli is a versatile vegetable that people love eating raw, steamed, or sauted. And along with its versatility, it's also a great addition to your eating plan when you're trying to shed a few pounds.

"Broccoli contains antioxidants, which are known to lower the inflammation in the body, among other things. These nutrients in broccoli are unique in how they work," says Trista Best, MPH, RD, LD at Balance One Supplements.

"This vegetable also provides the body with sulforaphane, an antioxidant plant compound that gives this vegetable most of its anti-inflammatory benefits. Sulforaphane works by lowering cytokines and NF-kB, the substances that drive the inflammation process. When these are abundant in the body and allowed to persist dangerous levels of inflammation can be reached." As research shows that chronic inflammation can cause weight gain, being able to reduce it can help you lose weight.

Bell peppers are a delicious vegetable with a mild flavor, so they're great for adding to different types of dishes.

"Bell peppers are ideal vegetables to add to a weight loss diet. They are low in calories and high in nutrients while also helping to create a sense of fullness after meals. This combination can help to prevent overeating throughout the rest of the day," says Best.

In addition to supporting weight loss, "bell peppers are also packed full of nutrients that benefit the body in significant ways, yet most of the general public is unaware of how healthy they actually are. Red bell peppers are higher in vitamin C than oranges, which is an important nutrient for immune support benefits but also improves the absorption of iron.

Things like onions, garlic, scallion, shallot, leek, and chives are considered alliums. These veggies are flavor-packed and great for a healthy meal plan, and because they're so high in flavor, they can make up for higher-calorie flavor additives you may add to food.

"These low-calorie, high-flavor vegetables can be used in so many ways from soups to sauces, seasonings and salads, and more. One of the easiest ways to reduce total calories is to go for a whole-foods flavor and swap out ultra-processed dressings and sauces, soups, and other packaged foods that while may provide you with familiar flavors, they come with very little nutrients and lots of extra empty calories," says Jonathan Isbill MS, RD, LD, Master's in Nutrition and Dietetics, Registered Dietitian, Holistic Health Coach, and Educator.

As a bonus, Isbill notes that onions "are also a great source of whole food prebiotics to support a healthy microbiome balance and happy digestion."

If you're someone who can handle a little bit of spice in the kitchen, you may want to try adding some hot peppers to your next meal to support weight loss!

"I love adding hot peppers and chili peppers to someone's meal plan to boost flavor and heat to their dishes. The interesting thing about veggies that come from the capsicum genus of plants is that they contain Capsaicin, which has been known to boost mood and metabolism and reduce inflammation while also promoting an endorphin release and giving some people an extra calorie burn. Capsaicin can heat up the body's temperature and cause you to burn off a few extra calories thanks to this thermic effect of these foods," says Isbill.

Some people love beets, others hate them. But if you're a beet-lover, you'll be happy to know that they are packed with plenty of helpful nutrients to aid in weight loss.6254a4d1642c605c54bf1cab17d50f1e

"Being rich in nitrates, beets have been long appreciated by athletes and high performers as a way to increase nitric oxide in the body. This extra boost of NO can help fuel workouts, support blood flow, maximize recovery, and may even boost performance for some," says Isbill. And when you get more out of your fat-burning workouts, you can support your weight loss goals.

"Many people enjoy beetroot juice, and you can also saut their greens in stir-fry, add them to a salad, or blend them in a smoothie," he adds.
