Dogs provide a much better model for studying human aging. They are unique in sharing our environment. Pet dogs live in our homes with us, breathe the same air we do, and often share our exercise routines, to some degree. Theyre eating our food, theyre walking on our lawns with pesticide, theyre drinking whatever is in our water, says Elaine Ostrander, who leads a team studying human and dog genetics at the National Human Genome Research Institute of the National Institutes of Health in Bethesda, Maryland.

They also develop many of the same age-related diseases that we do. Technically, most pet dogs die as a result of euthanasia. But in most of these cases, the animals have cancer, says Kaeberlein. Dogs can also develop heart disease in later life, just like humans. There are some differencesdog brains arent the same as human ones, although the animals do seem to develop a form of dementia. And dogs dont tend to develop vascular diseases as humans do.

But there are plenty of similarities. Both dogs and people experience aging of the immune system and an increased risk of kidney disease as they get older, says Kaeberlein. It seems like at the level of individual age-related diseases, its very, very similar, he says.

One main difference is that aging is a much quicker process in dogsit happens around seven times faster than in humans, though small dogs generally live longer than larger ones. (Its not quite the case that one year of dog life is equivalent to seven human years, however. Dogs seem to age more rapidly than humans do in their first years of life, and the pace slows as they get older.)

While this can be devastating for devoted owners, it is useful for researchers, who are able to study the effects of potential anti-aging drugs over the entire life spansomething that is much more difficult to achieve in people.

Another unique feature of dogs is their incredible diversity. Only in dogs do we see such extreme differences in size and appearance within a single species. A Great Dane is around 20 times heavier than a Chihuahua, for example. A Pomeranian looks nothing like a Staffordshire bull terrier.

This variation makes the animals particularly fascinating to geneticists like Ostrander. Dogs were only domesticated around 30,000 years ago, and most breeds have only been around since the Victorian times, she says. It was around the mid-1800s that modern dog breeding took off, and owners bred dogs for aspects of their appearance, such as a curly coat or a flat face. Breeders essentially selected dogs with genes for these features.

Because many such modifications only occurred in the last hundred or so years, genetic differences between todays dog breeds are likely to have a significant impact on these traitsand on the risks of certain diseases that vary between breeds.

Chewable Flintstones vitamins have been around for generations, outliving the popular cartoon TV show for which they were named. But a video shared on social media claims the childhood supplement is potentially deadly.

"The Toxic Ingredient in Your Kids Vitamins," read the words across the top of the July 28 Facebook video that shared a clip from a podcast. In it, guest Gary Brecka warns against the vitamin B12, which he says is an ingredient in Flintstones and other supplements.

"The most common form of B12 in the world is entirely synthetic. We make it from hydrogen cyanide," said Brecka, who describes himself in his LinkedIn profile as founder of a Florida-based health business. "Its called cyanocobalamin. Its a cyanide-based B12. I mean its hard to believe that were allowed to make vitamins out of hydrogen cyanide in this country, but we are. Flintstones vitamins have cyanocobalamin."

The post was flagged as part of Facebooks efforts to combat false news and misinformation on its News Feed. (Read more about our partnership with Facebook.)

Is it true that childrens vitamins have synthetic cyanide? We reached out to Brecka to ask for more information to support his statements, but did not receive a response in time for publication.

Flintstones vitamins do contain cyanocobalamin, which is man-made B12. But the videos claim that the ingredient is toxic is wrong.

The Mayo Clinic describes B12 as a vitamin that "plays an essential role in red blood cell formation, cell metabolism, nerve function and the production of DNA, the molecules inside cells that carry genetic information."

According to the National Institutes of Health, B12 is naturally present in some foods, notably animal products, and dissolves in water. Its also added to foods or given as a supplement, the agency wrote. In The synthetic form, cyanocobalamin, is usually given to people who have low levels of B12.

NIHs fact sheet for health professionals says B12 has a "low potential for toxicity." The agency notes that cyanocobalamin is also safe no overdosage occurs.

"Even at large doses, vitamin B12 is generally considered to be safe because the body does not store excess amounts," read the fact sheet.

A separate NIH fact sheet, written for consumers, also states that B12 supplements are safe, even at doses higher than recommended and for the same reason: "the body absorbs only a small percentage of it," it says.

Dr. Herman B. Gray, chair of Wayne State Universitys Department of Pediatrics, told PolitiFact that for most people, eating a balanced, healthy diet provides enough B12, and taking a supplement is usually unnecessary. But, he said, "it is safe to take in prescribed dosages, including for children."

Cyanocobalamin is not the same as the poison cyanide, Gray said. Cyanocobalamin has only a molecule of cyanide, which is not enough to cause poisoning.

In an article on B12 supplements, the science and technology news site Gizmodo explained it this way: "Dont panic. The body can deal with small amounts of cyanide, usually by using sodium thiosulfate, converting the cyanide ions to thiocyanate, which you then excrete. Cyanocobalamin is safe, and found in food additives, health supplements and the injections that doctors give patients with anemia."

Gray concurred, noting that B12 has been used safely for decades. "Vitamin B-12 or cyanocobalamin is not toxic," he said.

Our ruling

A video on a Facebook post claims that the synthetic form of B12 found in childrens vitamins is toxic.

Cyanocobalamin is man-made B12, but health organizations and pediatricians say its safe to consume.

We rate this claim False.

Signs you may be drinking too much water

It's quite common to hear of people are not drinking enough water, but is it possible to drink too much water?

Buzz60, Buzz60

In hot weather, dehydration can sneak up on a person but it can be prevented, along with the health problems it can create.

Dehydration results from the loss of too muchfluid from the body, depriving the body of adequate fluids to function properly.

High temperatures plus inadequate fluid can lead to dehydration which can increase risk for heatstroke, a life-threatening condition resulting from the body'sinability to control its core temperature.

Drink more fluids regardless of activity levels.

If your doctor limits the amount you drink or has you on water pills, ask how much you should drink while the weather is hot.

Replace salt and mineralsHeavy sweating removes salt and minerals from the body that need to be replaced. A sports drink can replace the salt and minerals you lose in sweat.

Talk to your doctor If you are on a low-salt diet, have diabetes, high blood pressure, or other chronic conditions, talk with your doctor before drinking a sports beverage or taking salt tablets.

Keep pets hydrated Provide plenty of fresh water for your pets, and leave the water in a shady area.

Waiting until you feel thirsty Good hydration means preventing issues before they start.

Energy drinksSome energy drinks contain much more caffeine than standard servings of coffee, tea, or soft drinks, and contain more sugar than soft drinks and add more calories. Drinking several energy drinks per day can raisecaffeine levels and affect the heart.

Alcohol Alcohol can cause dehydration. Drinking alcohol within 24 hours of working in the heat can increase the risk of heat illness.

For work safety, the Centers for Disease Control and Prevention recommends:

"Right off the bat, I'd say the average person needs about 3.7 liters of water, just shy of a gallon each day. That is before you take into account how active someone is," said Gordon Levine, exercise specialist at the Somerville-based Boston Sports Medicine.

Problems can occur when people don't recognize the risk, saidDr. Mary Lynn Joe, medical director ofCircle Health's urgent care services, located in Westford, Dracut, Tewksbury and Billerica.

"We get people who aren't prepared, especially people who work outside, especially laborers," Joe said. "But it could be homeowners, trying to attend to their landscaping. Due to the drought, they are not prepared."

Joe said, "It's important to wear light colors, and drink plenty of water to stay hydrated. We still see people with symptoms nausea, dizziness, dehydration. Some have altered mental status."

Hydration can play a role injury prevention and healing, said Gordon Levine, exercise specialist at the Somerville-based Boston Sports Medicine.

Boston Sports Medicine offers physical therapy and related services at locations inBrookline, Swampscott, Watertown, and Wilmington.

"If someone is chronically dehydrated, that can effect their ability to heal from an injury, or conditions such as arthritis. Someone with arthritis might feel more pain."

Levine said, "Muscles might be stiff. It can both slow down the healing process, as well as exacerbate painful symptoms."

A larger person, or person doing increased activity, is going to need more, Levine said.

Water is important, but so is the movement of electrolytes minerals in the blood and other body fluids that carry an electric charge.

"They help joints and muscles communicate," Levine said. "If you are just replacing the water in your body, you may be hydrated, but you are still at risk of non-optimal function."

Sports drinks such as Gatorade can help, but Levine urged avoiding sports drinks that are high in sugar. Well-planned snacks and meals can also keep electrolytes at a good level, Levine said.

Gregory Wellenius, professor of environmental health at Boston University School of Public Health,said, "The body has mechanisms to retain or dissipate heat."

When things get too hot, Wellenius said, "A lot of it is through sweating, and diverting more flood flow to the skin. This has consequences for the cardiovascular system, and consequences for other areas of the body."

Wellenius said, "You start to see the symptoms consistent with dehydration heat exhaustion and heat stroke, which can be deadly if you don't get medical attention on time."

Wellenius added,"People don't realize how much water they are losing through sweating or evaporations...we have this image of elderly individuals being at high risk, and I think that's true, but I think that is too narrow a view," Wellenius said.

Heat and dehydration can also affect the central nervous system, including brain function and stress response.

Wellenius co-authored a study, published in February in the Journal of the American Medical Association, which suggests that during extreme heat, more people go to the emergency room seeking mental health care.

Heat may impair the brain's ability to perform tasks such as mental arithmetic, the ability to drive a vehicle safely, and overall judgement.

Wellenius said heat can also add to the stresses of every day life. "It affects markers of brain health, such as anxiety and depression."

Wellenius said here in Massachusetts, much of our architecture hasn't been planned for life in hot weather, but instead for standing up to the traditionally unforgiving New England winter.

More: State law: When are you protected from utility shutoff?

State law prohibits utility shutoff from Nov. 15-Marh 15 if utility service is needed for heat. However, Wellenius noted there is no similar provision during hot summer months.

For places without air condition, or other protections from heat, such as parks and shade trees, Welleniu said the temperature doesn't have to trigger a heat advisory to create a problem. "It's also the days that are not as extreme."

Costly confusion

The United States Department of Agriculture reports that in 2020 the average American household spent 12 percent of its income on food. But a lot of food is simply thrown away, despite being perfectly safe to eat. The USDA Economic Research Center reports that nearly 31 percent of all available food is never consumed. Historically high food prices make the problem of waste seem all the more alarming.

The current food labelling system may be to blame for much of the waste. The FDA reports consumer confusion around product dating labels is likely responsible for around 20 percent of the food wasted in the home, costing an estimated US$161 billion per year.

It's logical to believe that date labels are there for safety reasons, since the federal government enforces rules for including nutrition and ingredient information on food labels. Passed in 1938 and continuously modified since, the Food, Drug, and Cosmetics Act requires food labels to inform consumers of nutrition and ingredients in packaged foods, including the amount of salt, sugar and fat it contains.

The dates on those food packages, however, are not regulated by the Food and Drug Administration. Rather, they come from food producers. And they may not be based on food safety science.

For example, a food producer may survey consumers in a focus group to pick a "use by" date that is six months after the product was produced because 60 percent of the focus group no longer liked the taste. Smaller manufacturers of a similar food might play copycat and put the same date on their product.

One industry group, the Food Marketing Institute and Grocery Manufacturers Association, suggests that its members mark food "best if used by" to indicate how long the food is safe to eat, and "use by" to indicate when food becomes unsafe. But using these more nuanced marks is voluntary. And although the recommendation is motivated by a desire to cut down on food waste, it is not yet clear if this recommended change has had any impact.

A joint study by the Harvard Food Law and Policy Clinic and the National Resources Defense Council recommends the elimination of dates aimed at consumers, citing potential confusion and waste. Instead, the research suggests manufacturers and distributors use "production" or "pack" dates, along with "sell-by" dates, aimed at supermarkets and other retailers. The dates would indicate to retailers the amount of time a product will remain at high quality.

The FDA considers some products "potentially hazardous foods" if they have characteristics that allow microbes to flourish, like moisture and an abundance of nutrients that feed microbes. These foods include chicken, milk and sliced tomatoes, all of which have been linked to serious foodborne outbreaks. But there is currently no difference between the date labelling used on these foods and that used on more stable food items.

Infant formula is the only food product with a "use by" date that is both government regulated and scientifically determined. It is routinely lab tested for contamination. But infant formula also undergoes nutrition tests to determine how long it takes the nutrients - particularly protein to break down. To prevent malnutrition in babies, the "use by" date on baby formula indicates when it's no longer nutritious.

Nutrients in foods are relatively easy to measure. The FDA already does this regularly. The agency issues warnings to food producers when the nutrient contents listed on their labels don't match what FDA's lab finds.

Microbial studies, like the ones we food safety researchers work on, are also a scientific approach to meaningful date labeling on foods. In our lab, a microbial study might involve leaving a perishable food out to spoil and measuring how much bacteria grows in it over time. Scientists also do another kind of microbial study by watching how long it takes microbes like listeria to grow to dangerous levels after intentionally adding the microbes to food to watch what they do, noting such details as growth in the amount of bacteria over time and when there's enough to cause illness.

Determining the shelf life of food with scientific data on both its nutrition and its safety could drastically decrease waste and save money as food gets more expensive.

But in the absence of a uniform food dating system, consumers could rely on their eyes and noses, deciding to discard the fuzzy bread, green cheese or off-smelling bag of salad. People also might pay close attention to the dates for more perishable foods, like cold cuts, in which microbes grow easily. They can also find guidance at FoodSafety.gov.

Food expiration dates don't have much science behind them: food safety researcher explains another way to know what's too old to eat - Newshub

The watermelon diet may be 2022s version of the 1970s trendy grapefruit diet. A lot of fad diets can thank a celebrity connection for their popularity for the grapefruit diet, that was reportedly Brooke Shields. And for the watermelon diet, its Gabi Butler, who explained to her mom on an episode of the hit Netflix series Cheerthat she and a teammate were going on the watermelon diet as a cleanse for a few days.

Asked about the diet by Katie Krause on Extra in January, Butler said, It's basically a watermelon fast. You're not actually fasting, because you're getting something in your stomach. She added, I will do it every once in a while when I feel like I've just been eating really bad, not only for my physical appearance but for my mental state, too Its not something that is unhealthy. It actually is very good for you at removing all that toxic stuff. What watermelon does is it basically clears everything because it is mostly water.

But do dietitians agree with Butler? Here's an in-depth look at the diet, along with what they had to say.

Different versions of the watermelon diet have been making their way around the internet. At its core, the diet involves eating nothing but watermelon for a set time period. Common variations run from three to seven days, and after that, you add in some or all of the foods you normally eat, with or without watermelon. Since watermelon is a low-calorie food one cup of diced watermelon has about 46 calories, according to the U.S. Department of Agriculture (USDA) this diet is very low in calories. Its considered a cleanse or detox diet.

YouTubers who try it brag about losing lots of weight 13 pounds in seven days, for example, and say they stop craving junk food, clear their skin, have more mental clarity and energy, and feel lighter and less bloated.

But the dietitians we spoke with aren't fans. [Gabi Butlers] advice about the watermelon diet is more toxic than the toxins that she's trying to get rid of with this cleanse, says Bonnie Taub-Dix, RDN, the creator of BetterThanDieting.com and the author ofRead It Before You Eat It: Taking You From Label to Table. Its a shame that she doesnt understand her importance as a role model. Unfortunately, people like Butler who are in the public eye can influence fans to try fad diets like this one.

Im a huge fan of watermelon and fruit in general, but this diet is not helpful, says Samantha Cassetty, RD, the New York Citybased coauthor of Sugar Shock. Watermelon happens to be a very healthy food, but there's no evidence that eating it exclusively is a healthy thing to do. In fact, it's the opposite.

Both Cassetty and Taub-Dix are skeptical of cleanses in general. Theres no scientific validity to doing a cleanse, Cassetty says. The idea that you could eliminate toxins by just eating watermelon is totally untrue.

Taub-Dix points out that you dont need a restrictive diet to cleanse your body your liver and kidneys do that for you.

Long-term consumption of a high-fat diet can harm your brain and cause obesity.

According to recent research, eating fatty meals may not only increase your waistline but also damage your cognitive function.

A clear relationship has been shown between mice given a high-fat diet for 30 weeks, causing diabetes, and a subsequent decline in their cognitive abilities, including the onset of anxiety, depression, and worsening Alzheimers disease. The international study wasconducted by neuroscientists Professor Xin-Fu Zhou and Associate Professor Larisa Bobrovskaya of the University of South Australia.

Due to poor metabolism brought on by brain alterations, mice with reduced cognitive function were also more prone to put on excessive weight.

Researchers from Australia and China recently reported their results in the journal Metabolic Brain Disease.

Associate Professor Larisa Bobrovskaya, a neurologist and biochemist at the University of South Australia, says the study adds to the increasing body of data connecting diabetes and obesity with Alzheimers disease, which is expected to affect 100 million people worldwide by 2050.

Obesity and diabetes impair the central nervous system, exacerbating psychiatric disorders and cognitive decline. We demonstrated this in our study with mice, Assoc Prof Bobrovskaya says.

In the study, mice were randomly allocated to a standard diet or a high-fat diet for 30 weeks, starting at eight weeks of age. Food intake, body weight, and glucose levels were monitored at different intervals, along with glucose and insulin tolerance tests and cognitive dysfunction.

The mice on the high-fat diet gained a lot of weight, developed insulin resistance, and started behaving abnormally compared to those fed a standard diet.

Genetically modified Alzheimers disease mice showed a significant deterioration of cognition and pathological changes in the brain while fed the high-fat diet.

Obese individuals have about a 55% increased risk of developing depression, and diabetes will double that risk, Associate Prof Bobrovskaya says.

Our findings underline the importance of addressing the global obesity epidemic. A combination of obesity, age, and diabetes is very likely to lead to a decline in cognitive abilities, Alzheimers disease, and other mental health disorders.

Scientists Discover That This Type of Diet Can Shrink Brains - SciTechDaily

Veganism is a growing practice with the number of people following a vegan diet or lifestyle in the United States increasing from around 1% in 2014 to roughly 10% in 2022.

However, in addition to its health benefits, research has also indicated a link between the vegan diet and a higher susceptibility to fractures and low bone mineral density.

Studies show that resistance training can stimulate bone formation, whereas other common sports such as cycling or swimming do not affect bone mineral density.

Knowing how different forms of physical activity affect bone mineral density among vegans could help inform public health recommendations.

Recently, researchers assessed the bone microarchitecture of vegans and matched omnivores.

They found that vegans who engaged in resistance training had a higher bone mineral density than vegans who engaged in aerobic exercise or no exercise at all.

They also found that vegans and omnivores who engaged in resistance training had similar bone structures.

Veganism is a global trend with strongly increasing numbers of people worldwide adhering to a purely plant-based diet, said Dr. Christian Muschitz, of St. Vincent Hospital Vienna and the Medical University of Vienna in Vienna, Austria, one of the studys authors.

Our study showed resistance training offsets diminished bone structure in vegan people when compared to omnivores. People who adhere to a vegan lifestyle should perform resistance training on a regular basis to preserve bone strength. Dr. Christian Muschitz

The study was published in The Journal of Clinical Endocrinology and Metabolism.

For the study, the researchers recruited 43 healthy, non-obese men and women who had been on a plant-based diet for at least five years. They also recruited 45 non-obese men and women who had been on an omnivore diet for at least five years.

They assessed each participants bone mineral density via a noninvasive imaging technique known as high-resolution peripheral quantitative computed tomography (HR-pQCT).

They also took fasting blood samples from participants and asked them to complete questionnaires detailing their diet and physical activity levels.

Nine women and 11 men in the vegan group reported progressive resistance training on a regular basis alongside 8 women and 17 men from the omnivore group.

Resistance training is not limited to lifting weights, Dr. Sabrina Corbetta, associate professor at the Department of Biomedical, Surgical and Dental Sciences at the University of Milan, who was not involved in the study, told Medical News Today.

Resistance training is a form of exercise intended to increase muscular strength and endurance. It involves exercising muscles using some form of resistance. This resistance could be weights, bands, or even your own body weight working against gravity, she added.

After analyzing the data, the researchers found that vegans who did not engage in resistance training had significantly diminished bone microarchitecture compared to non-resistance training omnivores.

However, they also noted that vegans who engaged in resistance training at least once per week had a similar bone structure to omnivores who also engaged in resistance training.

They further noted that vegans performing exclusively aerobic activities had similar bone microarchitecture to vegans who performed no sports at all.

The researchers also found that serum markers of bone turnover were within healthy values for both groups; however, the omnivore group had significantly higher calcium levels.

To explain their findings, the researchers noted that lower calcium levels in the vegan group might be explained by a lower calcium intake.

They also wrote that vegans who engaged in weight training likely had higher bone mineral density as progressive resistance training causes mechanical strain that increases bone modeling.

Dr. Corbetta added that the benefits of resistance training on bone metabolism extend beyond stimulating bone turnover. She noted that they also include modulation of the metabolism of various minerals, including calcium, phosphate, and parathyroid hormone (PTH).

The researchers concluded that in addition to a well-planned diet, regular progressive resistance training should be a part of the vegan lifestyle.

Dr. Corbetta noted that a significant proportion of vegan subjects included in the study consumed supplements.

Adequate intake of vitamin D and B12 can be achieved in vegans only by consuming supplements or fortified foods. Vegans should pay particular attention, mainly in postmenopausal age, to maintaining an adequate intake of all micronutrients recognized as important for bone health. Dr. Sabrina Corbetta

When asked about the studys limitations, Dr. Corbetta said: The study has an observational design, and [so a cause-effect relationship cannot] be drawn. An interventional study should be conceived and performed to demonstrate that resistance training may prevent vegan diet-related derangement of bone microarchitecture.

Dr. Muschitz also told MNT that the study sample was too small to draw conclusions about a possible elevated fragility fracture risk among vegans.

Why weight training is important if you have a vegan diet - Medical News Today

Fed Up is a podcast about a trendy diet plan gone wrong, the creator Tanya Zuckerbrots story, and a whistleblower who exposed F-Factor on social media. The podcast chronicles Emily Gellis whistleblowing quest after she heard widespread rumors about peoples F-Factor-related health issues. Emily learned that F-Factors users experienced terrible side effects after following Tanyas fiber-rich diet plan complete with bars and powders. This series deep-dives into diet culture, wellness, wealth, and modern influence.

Emily, a fashion and beauty influencer, used her social media platform of over 100,000 Instagram followers to bring attention to F-Factors fiber empire that triggered a feud, attracted media attention, legal action, and plenty of Internet trolls.

Narrated by Casey Wilson, this Wondery podcast will release new, weekly episodes through August. Subscribers have early access to all 6 episodes, running less than 30 minutes on average.

The podcast examines whats marketed as healthy, allegations against F-Factors side effects, and a national media circus that spiraled as more people came forward. The controversy started in 2020 as people shared their horrifying F-Factor experiences with Emily and the media. The alleged health issues ranged from bloating, gas, cramps, and rashes to having part of their colon removed. Some claimed that F-Factor caused its followers to struggle with eating disorders.

Over the years, Tanya built a solid fanbase, devoted to following her companys fiber-filled protocol. And as allegations stacked up against Tanyas company, Tanya and her loyalists hit the ceiling. Tanya wound up filing a $500,000 defamation lawsuit against Emily, and she has countersued.

Tanya, known for her nutrition counseling and lifestyle content posts, continued to tout the safety of F-Factors products. Tanya claims that all products are thoroughly tested and efficient as part of her program. The lawsuit claimed that Emily made false statements about F-Factors criminal behavior as well as Emilys supposed lies that Tanya threatened to kill her family.

Hear the full story and resulting investigation in Fed Up, with new episodes released over the next few weeks.
