America’s Most Popular Cooking Oil Linked to Obesity in New StudyDec 01, 2025 at 10:18 AM EST By Jasmine Laws, US News Reporter A new study has found that soybean oil contributed to obesity in mice, prompting concern that the United States' most popular cooking oil could be playing a role in the country's obesity problem. The University of California, Riverside study, published in the Journal of Lipid Research in October, investigated how mice metabolized linoleic acid, an omega-6 fatty acid widely present in soybean oil, by feeding them a high-fat diet based on the common cooking oil. While the study was conducted on mice, Frances Sladek, a UCR professor of cell biology and author of the study, told Newsweek that the findings "were translatable to humans as the pathways we found involved in soybean oil-induced obesity are highly conserved between mouse and human." Why It MattersSoybean oil is by far the most widely used cooking oil in the country, with rapeseed oil second and palm oil third, according to data from Statista. Soybean oil is also made up of more than 50 percent linoleic acid, Sladek said. The finding raises notable concern, not only because of the oil's popularity, but also because of America's high obesity rates—one in five children and two in five adults are obese in the U.S., meaning they have a Body Mass Index (BMI) higher than 30. Obesity is known to be associated with higher risks of health problems, including diabetes, heart disease and strokes. The American diet has also been called into question by studies previously, as last year a study found that the majority of Americans ate a diet that promoted inflammation, increasing the risk of diseases such as heart disease, obesity, diabetes, depression and certain cancers.

These molecules are what linoleic acid is broken down into in the body, and so the higher the consumption of the acid, the higher the amount of these molecules will be in the body. While other fatty acids also break down into oxylipins, the oxylipins derived from linoleic acid were the ones the authors found contributed to obesity in mice. The finding is not new; the researchers noted this result in a previous study. What they did differently in this study was test the impact of a diet high in soybean oil in a group of male mice genetically engineered to express a different version of a liver regulatory gene, P2-HNF4α. This meant they had different metabolic pathways from the control group, as the genetic change reduced the activity of enzymes that convert linoleic acid into oxylipins. The researchers found that the modified mice had healthier livers and gained less weight than the control group on the same diet, further supporting the idea that oxylipins contribute to obesity. “This may be the first step toward understanding why some people gain weight more easily than others on a diet high in soybean oil,” said Sonia Deol, a UCR biomedical scientist and another author of the study. Although the researchers also note that the genetically modified mice had elevated oxylipins on a low-fat diet without becoming obese, suggesting that other metabolic factors are at play. Sladek said that they found that "it is the levels of the oxylipins present in the liver, not circulating in the blood, that correlate with obesity." However, he said that they aren't yet certain about "exactly how the oxylipins drive obesity." How Much Soybean Oil Do Americans Actually Consume?Consuming a small amount of linoleic acid is actually required for human health and is part of a healthy diet; however, the researchers noted that America has had a "remarkable increase" in its consumption of the oil over the past 50 years. The required amount of linoleic acid for health is around 1 to 2 percent of a person's calorific intake, the study authors noted, as small amounts play an important role in maintaining good health. Most Americans broadly have a much higher intake of linoleic acid at around 15 to 25 percent of their calorific intake, the study authors said. Sladek said that consuming small amounts of soybean oil is "perfectly safe and provides a good source of the essential fatty acid linoleic acid." He said that the problem is that "processed foods are becoming an ever larger part of our diet and many of those foods have soybean oil in them, or they have corn oil, safflower seed oil, sunflower seed oil — all these seed oils are made up of large amounts of linoleic acid, just like soybean oil." "So in general, we are taking in much more of these seed oils, all of which have high levels of linoleic acid, than our body needs," he added. What Does Soybean Oil Do to Your Body?It is not clear from the study how these findings would translate to the human body, and further research is needed to determine the impact of soybean oil on human health. However, the study authors note that the findings suggest the possible link warrants further investigation. Sladek said: "It took 100 years from the first observed link between chewing tobacco and cancer to get warning labels on cigarettes. We hope it won’t take that long for society to recognize the link between excessive soybean oil consumption and negative health effects." He also told Newsweek that in previous research, the team found that the soybean oil could impact the intestines, the microbiome and the hypothalamus. He said that while there is a growing body of evidence indicating that dietary linoleic acid is beneficial for the heart, "we have not looked at the impact of a soybean oil diet on the heart." "Different organs will respond differently to dietary linoleic acid and more research in general needs to be done," Sladek added. Other experts are not convinced of the findings, though. Dr. Dariush Mozaffarian, the director of the Food is Medicine Institute at Tufts University, told Newsweek: "Much of the original research suggesting harms of omega-6 [polyunsaturated fatty acids], like this study, was done in mice or rats." "We’ve since clearly learned that humans are not mice, and that these effects don’t translate to what’s seen in humans," Mozaffarian said. "In mice, for example, high fat diets (from any source) cause obesity, whereas in humans, carbs are the problem." He said that in controlled trials in humans, soybean oil and omega-6 polyunsaturated fatty acids were found to "improve blood cholesterol levels, improve glucose control, and lower risk of heart attacks," while in "observational studies," these oils are "linked to less weight gain and obesity risk." Mozaffarian said that soybean oil is a "healthy oil for cooking," and pointed to studies finding that a tablespoon and a half daily of soybean oil could reduce the risk of coronary heart disease, that the oil does not have pro-inflammatory effects, and that those who consumed 5 grams a day had a lower risk of "all-cause mortality."

Yikes! Yeah, I would freak out also. I'm assuming these symptoms eventually resolved, right? How long did it take? I'm a Google graduate also, lol

I stayed zero carb as well. But both my side of the family and my wife's side of the family no longer holds any get-togethers, so it's just another day for us. My son's girlfriend and her father came over and we binge-watched the first volume of Stranger Things season 5. She made a lasagna type dish with rogatoni's in it, which I of course didn't have. But her and her father also made some sausage links in a crock pot with some peppers and a tomato sauce. The father had his on a hoagie bun, and I had mine on some Egg Life Wraps.

In the past it was painful to view forums on a mobile device, so Tapatalk was the solution. It's not so important for us today though. The software than runs Carnivore Talk has a pretty good mobile display using a regular browser.

I take 10,000 IU's a day, which I do NOT recommend that other people do. I spill the protein that binds to vitamin D (because of my kidney disease) so even though I take such large amounts, I can't get my Vitamin D-25 any higher than 50-55. Toxicity potentially becomes an issue above 100-120. Most people will do well with a single 500 to 2000 IU capsule daily if you aren't in the sun often.

Hello everyone, There will be no livestream tonight. Today is an 'anniversary' of a tragic moment in years gone by, and my wife wants to get out of the house and do something fun to keep her mind busy. So naturally I am going to be a good husband and oblige. Hope you all understand. - Bob

When I was a kid my dad was a hunter. He often brought back deer and tried to convince me it was Rudolph or Bambi, lol. He would process it himself in the garage and kitchen, and send the heads away to a taxidermist (??) which then sent them back and they are still on his wall to this day.

Those of us who make up the carnivore community need to focus on building up and encouraging one another, and not laying down an bunch of rules and then telling others that they aren't a "true carnivore" because they might not be as strict as can be. A carnivore-centric diet can of course be strict for some, but it doesn't have to be for everyone. A hypercarnivore, by definition, consumes 70% or more of their diet from animal products.

This supplement dramatically cuts heart attack risk, scientists sayStory by Vishwam Sankaran A pharmacist removes boxes of "Uvesterol D" vitamin medication from a shelf© AFP via Getty Images Scientists have found tailoring the intake of vitamin D in patients diagnosed with heart disease can dramatically cut the risk of heart attacks. The finding suggests individualising vitamin D doses for patients based on their blood levels rather than administering uniform “one-size-fits-all” doses as has been done commonly until now. Vitamin D is a hormone mainly synthesised in the skin via sunlight exposure, and is known for its positive effects on inflammation and heart health. Widespread vitamin D insufficiency and the growing burden of heart disease globally emphasise the need for simple, cost-effective interventions to reduce death risk. While low vitamin D concentration is linked to adverse heart disease outcomes, intervention studies until now have yielded inconsistent results, researchers say. Now, scientists call for tailoring vitamin D intake for each patient to achieve optimal circulating levels as a key strategy to mitigate heart disease risk. “Our results suggest that targeting vitamin D supplementation based on blood levels can significantly diminish the risk of subsequent heart attacks,” said epidemiologist Heidi T May from Intermountain Health. “This approach demands a personalised, vigilant clinical protocol that diverges from the traditional fixed-dose model,” said Dr May, an author of the study presented at the American Heart Association’s Scientific Sessions 2025. Researchers recommend a rigorous monitoring protocol which adjusts vitamin D supplementation every three months. The latest clinical trial assessed 630 adult participants diagnosed with acute heart disease at Intermountain Medical Center in Utah for a six-year period, with an average follow-up of just over four years. Nearly half had a history of prior heart attack. Over 85 per cent of participants initially had suboptimal vitamin D levels below 40 nanograms per millilitre (ng/mL) of blood, underscoring widespread insufficiency of the hormone in this population. Researchers grouped the participants randomly into two groups – one, which received standard care without vitamin D level management, and another treatment arm, which underwent serial blood testing and personalised dosing of the hormone to surpass the 40 ng/mL threshold safely. Scientists found that the treatment group experienced a 52 per cent reduction in the risk of recurrent heart attacks compared to controls. This finding marks one of the most significant effect sizes reported in recent vitamin D cardiovascular research, researchers noted. However, researchers urge doctors to be cautious of the findings as it remains to be corroborated by larger, peer-reviewed trials. Nonetheless, they say the data could pave the way for new heart attack prevention strategies centered on nutrient optimisation.

Sorry for the delay. I've had a crazy few weeks in real life due to a large construction project were on. And there's like zero cell signals there so all day long my phone is useless. Hydrocortisone cream my provide some relief. Keto rash is a common topic and there's a plethora of information out there, along with various ideas as to what causes it and how to prevent it. https://www.bing.com/search?q=ketp+rash

If we tag her like this ---> @Asmaa or quote her words, she should get an email letting her know we're talking about her :) So what were the results?

So let's start by describing your symptoms. Where is the rash? Is it all over or concentrated on certain parts of your body? Does it itch? I can understand why you might not be sure which it is, a keto rash or a histamine intolerance, since symptoms of the two can be similar. I wouldn't do this. Like @Geezy said, fat is your energy. I would still aim for 70% of your calories coming from fat and 30% coming from protein (this is acheived by basically eat 1g of fat for every 1g of protein). According to Dr. Boz, on variant of a Keto rash in an inflammation caused by little "critters" living in your skin that love glucose. If you are not eating enough fat, then your body will be working overtime to convert protein into glucose through a process called gluconeogenesis. It's as if you are eating carbs. They were initially starved when you started keto, but when you decided to lower the fat, your glucose production may have went up, and these little guys got excited and started multiplying. I'm not sure if I buy that, but she makes it make sense. If you are actively losing weight and burning your body fat, these could actually have toxins or histamines stored in them, which are being released into your blood stream. Again, where is the rash? Centrally located? Or all over? Some thoughts on how to test this yourself include adding back in 50-100 carbs a day for the next 2 weeks by adding fruit. This is called an "animal-based" carnivore diet (for whatever reason, lol). But STILL EAT the eggs, steak, and whatever else you have been eating. If it's keto rash, symptoms should alleviate and you can then try again with cutting the plants out. If it's histamines I wouldn't expect any changes. For keto rash, topical steroids will help for itching and oral antibiotics with help with inflammation. To test for histamines, aim for the freshest meat possible, straight from the butcher. Grocery store meat will have been hung and aged for weeks before packaging. Avoid jerky, canned meats, etc. For histamines, an antihistamine will help alleviate the itch. So if antihistamines help, your problem leans towards histamine intolerance. If hydrocortisone cream and an antibiotic help, then it's more likely keto rash.

Yes, through gluconeogenesis, the body synthesizes glucose from proteins to maintain blood sugar levels and prevent hypoglycemia, as certain cells in your body are dependent on glucose. While it's demand-driven, it's not a fast process. It can be triggered by fasting, but it doesn't really contribute meaningfully until after about 6 hours of fasting. Maybe a little sooner with intense exercise. So that intense exercise for most people (carb eaters) is fueled by glucagon that's already in your cells. Glucose in your blood can be quickly ushered into the cells with insulin. But if there is no glucose freely flowing in your veins and you are not fully fat adapted you will likely feel fatigued and weaker because your running low on energy. If you are fat adapted and the body is expecting these regular intense exercise sessions then it will have plenty of fat/ketones on hand.

I must say that I am once again a fan of the power bowl. Lately I have been mixing ground beef, scrambled eggs, breakfast sausage, and bacon all together. It's so tasty that cheese isn't even required, lol.

Excellent. I love hearing about carnivore successes, even the seemingly small ones that actually really really matter as they continue to add up. Keep doing what you are doing!

Thanks for sharing. I'll save this to listen to later. I listened to just a little random portion of it and it sounds like it might be a very good 2+ hour interview.

As expected. Carbs provide a lot of instantly available energy. Fat/ketones provide a steady stream of sustained energy. Consuming carbs is like throwing crumpled up newpaper into a fire. It instantly burns releasing energy. Eating fat is like throwing a log on that fire. The fire is going to keep burning for hours and is guaranteed not to go out. What I have heard is that yes, you will see a performance hit in the gym. But over time, as you become more and more fat adapted, you will eventually get back to those performance markers you were hitting previously. But it won't happen overnight, and it might even take a year.

This "quitting carnivore" or "adding back carbs" themes circle back around every couple years. It's mostly click bait, as mentioned above. Even my first video I made on my channel (2 years ago) I put the words "I almost quit carnivore" because it was trending back then. Although in my case, it was a true part of my story that I almost scared myself into quitting when I got blood work that I didn't expect, I admittedly put those words in there to attract interest, lol. In hindsight I kinda hate it and alway intend to make a new thumbnail for that video.

Protein Powders and Shakes Contain High Levels of LeadProtein supplements are wildly popular, but CR’s tests of 23 products found that more than two-thirds of them contain more lead in a single serving than our experts say is safe to have in a day By Paris Martineau Investigative Reporter Published October 14, 2025·Updated October 15, 2025 It's been 15 years since CR last tested for lead in protein powders and shakes. This time, the average level of lead was higher, and fewer products contained undetectable amounts of it. (Photo: Scott Meadows/Consumer Reports) Much has changed since Consumer Reports first tested protein powders and shakes. Over the past 15 years, Americans’ obsession with protein has transformed what had been a niche product into the centerpiece of a multibillion-dollar wellness craze, driving booming supplement sales and spawning a new crop of protein-fortified foods that now saturate supermarket shelves and social media feeds. Yet for all the industry’s growth and rebranding, one thing hasn’t changed: Protein powders still carry troubling levels of toxic heavy metals, according to a new Consumer Reports investigation. Our latest tests of 23 protein powders and ready-to-drink shakes from popular brands found that heavy metal contamination has become even more common among protein products, raising concerns that the risks are growing right alongside the industry itself. For more than two-thirds of the products we analyzed, a single serving contained more lead than CR’s food safety experts say is safe to consume in a day—some by more than 10 times.
