RFK Jr is not just bringing back infectious diseases like measles. Our top health official is working hard to back diet-related diseases like obesity, diabetes, and heart attacks. During his first three months in office, RFK, Jr. has made three big pronouncements about what Americans should eat. The first is important but for the wrong reasons. The second builds on the fallacies of the first. And the third goes against 60 plus years of scientific evidence.
1. Ultra-processed foodsare poisoning us
Something is poisoning the American people. And we know that the primary culprit is our changing food supply to highly chemical and processed food.

RFK is not wrong if he is referring to ultra-processed foods. A recent study found that those who ate more UPFs were more likely to show early symptoms of Parkinson’s disease and a review study linked UPFs to higher risk of dying from heart disease, type 2 diabetes, obesity, and mental health outcomes including anxiety and sleeping difficulties.
UPFs are made from multiple ingredients including additives like colorants, flavor enhancers, and preservatives. They contain high amounts of sugars, salt, and fats, which makes them hyper-palatable, or simply tasty. And they are cheap, readily available, and handy to eat. Unfortunately for the consumer, a review of studies with a combined population of over 1 million, found that for each 10% increase in UPF consumption, your risk of mortality increases by 10%.
Why are UPFs unhealthy? Many people eschew the long list of “chemicals” on the ingredient labels of everything from Wheaties to Fritos. One type of ingredient--food dyes--can have negative health effects and are associated with hyperactivity in children. In fact, MAHA hopes to ban food dyes in UPFs like soft drinks and Fruit Loops. Yet I haven’t heard MAHA alerting us to the high levels of salt, sugar, and saturated fat in UPFs… all things that have been shown over and over to contribute to chronic diseases like high blood pressure, diabetes, and cancer.FI/FOOD Washington Post Studio DATE: 1/7/05 PHOTO: Julia Ewan/TWP Kellogg's Fruit Loops now have 1/3 ... More less sugar and 12 added vitamins and minerals.The Washington Post via Getty Images
Dr Kevin Hall, who worked as a nutrition researcher at NIH for 21 years, found that people on an ultra-processed diet consumed about 500 more calories per day, which could explain why UPFs are associated with type 2 diabetes and obesity. But what explains why UPF consumers gobble up more calories? Dr Hall thinks energy density might be the culprit. Simply put, a chocolate chip cookie packs a lot more calories into every bite than a banana. So eating that ultra processed chocolate chip cookie means eating more calories per bite compared to eating fruit and other less processed foods. Not to mention that the sugar, salt and fat taste good… making me want to eat 4 or 5 chocolate chip cookies instead of one banana.

The preliminary results of Dr Hall’s recent study, which he posted on X, show that the high energy density and the irresistible taste of salt, sugar, and fat explain why people on high UPF diets eat more calories. But don’t expect to see the final results of this important study published anytime soon. Turns out Dr Hall took early retirement at 54 yrs old from his research position at NIH. Why? Because the MAHA administration forced him to withdraw his name from a paper on UPFs that mentioned “health equity”--or the difficulties some groups have accessing healthy food. The administration also took away the money Dr Hall needed to continue his UPF research, censored his media access, and even incorrectly edited his response to a NY Times inquiry. Just as we were on the brink of understanding why UPFs are making us sick, one of the world’s leading UPF scientists is out. Hard to see how lack of scientific information is Making Americans Healthy Again.

@RobertKennedyJr
Did you know that McDonald’s used to use beef tallow to make their fries from 1940 until phasing it out in favor of seed oils in 1990? This switch was made because saturated animal fats were thought to be unhealthy, but we have since discovered that seed oils are one of the driving causes of the obesity epidemic.

To be sure, consuming a lot of seed oils raises health concerns, including that they contain few nutrients, are often highly processed, and some, like soybean oil, might contain unhealthy amounts of omega 6 acids. But, are seed oils worse than saturated animal fats? Seed oils, unlike animal fats, are mostly unsaturated.
According to Dr. Christopher Gardner, director of nutrition studies at the Stanford Prevention Research Center who has been studying the role of fat in our diet since 1995, "Every study for decades has shown that when you eat unsaturated fats instead of saturated fats, this lowers the level of LDL cholesterolin your blood. There are actually few associations in nutrition that have this much evidence behind them…To think that seed oils are anywhere near the top of the list of major nutrition concerns in our country is just nuts."
And in a 2025 study, participants with the highest intake of butter, which similar to beef tallow is largely saturated animal fat, had a 16% less likely to die. About ⅓ of the deaths were due to cancer, about a third to cardiovascular disease, and a third other causes. The authors conclude:
“Substituting butter with plant-based oils may confer substantial benefits for preventing premature deaths. These results support current dietary recommendations to replace animal fats like butter with non hydrogenated vegetable oils that are high in unsaturated fats, especially olive, soy, and canola oil.”Still life featuring a collection of olive oil bottles, 2011.Getty Images
In short, if you have to choose between seed oils and animal fat, you are probably better off with seed oils, or even better, extra virgin olive oil. But, you should avoid consuming too much of any sort of oil or fat, which brings us to the third RFK Jr pronouncement.RFK Jr and West Virginia Governor Morissey. Presidential Candidate Robert F.

3. Become a Carni-Bro
At a public event to promote MAHA in West Virginia, RFK Jr body shamed Governor Patrick Morrisey for his weight.
I’m going to put him on a really rigorous regime. We’re going to put him on a carnivore diet … Raise your hand if you want Governor Morrissey to do a public weigh-in once a month. And then when he’s lost 30 lbs I’m going to come back to this state and we’re going to do a celebration and a public weigh in with him.
RFK, Jr.
MAHA seems to be at the forefront of the next culture war: dump plant-based foods and become a “carni-bro.” Yet a comprehensive review of studies on foods and obesity concluded:
High intakes of whole grains, legumes, nuts, and fruits are associated with a reduced risk of overweight and obesity, while red meat and sugar-sweetened beverages are associated with an increased risk of overweight and obesity.

How do UPFs compare to red meat? The only study I found comparing the two found people eating UPFs had an approximately 14% greater chance of dying whereas those who ate red meat had an approximately 8% chance of death over the same time period.But this study was conducted with Seventh Day Adventists, whose meat consumption was way lower than the average American. People in West Virginia, whose governor is in fact rotund, are by far and away the biggest consumer of hotdogs in the US, at 481 hot dogs per person per year.
In a recent UK study with a more typical population, every added 70 g of red meat and processed meatper day was associated with a 15% higher risk of coronary heart disease and a 30% higher risk of diabetes. Because red and processed meat consumption is also associated with higher rates of cancer, the World Cancer Research Fund recommends limiting red meat to no more than three portions per week and avoiding processed meat altogether.TOPSHOT - An overweight woman walks at the 61st Montgomery County Agricultural Fair on August 19, ...

Heart Disease: Still the leading killer
According to the CDC, heart disease is the leading cause of death in the US, accounting for one in five deaths, or one death every 33 seconds. Heart disease cost the US about billion from 2019 to 2020. And if you look at a map of where heart disease is more common, it looks uncannily like a map of MAHA supporters.
.Heart Disease Death Rates, 2018–2020 for Adults, Ages 35+, by CountyCDC
The first items in a list of CDC recommendations for preventing heart disease are all about food: Choose healthy meals and snacks high in fiber and limit saturated and trans fats, salt, and sugar. This sounds like a recipe for avoiding UPFs. But it could also be a recipe for substituting whole grains and fruit and vegetables for red and processed meats, which punch the double whammy of being meat and UPFs.
Is RFK, Jr. Making America Healthy Again?
Let’s celebrate Kennedy’s move away from UPFs, an important step toward improving Americans’ health. But why does our top health official publicly tout beef tallow, French fries, and double cheeseburgers, when we know that Americans’ consumption of saturated fat and meat lead to obesity, diabetes, cancer, and heart disease? Or has he weighed in on ultra-processed meats, like Slim Jim’s, which with sales at billion last year is America’s fastest growing snack?NEW ORLEANS - OCTOBER 01: Amanda Barrett, 18-years-old, watches her mother Eve Barrett peel a ...

It’s hard to understand what is going on in RFK’s brain. He gloms on to a limited number of studies suggesting health risks of eating seed oils, while ignoring saturated fats and even encouraging Americans to eat fast foods. He wants to rout out corruption in the food and pharmaceutical industry, yet uses his position to sell Make America Tallow Again hats and T-shirts. He says he believes climate change poses an existential threat, yet on his second day in office eliminated funding for research on heat waves, indoor mold after flooding, and other NIH climate change and health programs. And in his big May report on children’s health, he ignores the largest causes of death for those under 19--gun violence and accidents. Raise your hand if you want Secretary Kennedy to conduct a public truth-telling once a month.
