How Butter Could Fight Chronic Diseases in Americans
Something in US food supply is poisoning Americans - Robert F. Kennedy Jr.
The newly appointed US Secretary of Health and Human Sciences Robert F. Kennedy Jr. has touched off a firestorm in his pledge to Make America Healthy Again.
The 300 agriculture and food groups expressing their concerns with the Make America Healthy Again movement to RFDTV will no doubt put up a fight against any change as medical science butts heads with medical science.
Medical Science vs Medical Science
What is happening with RFK Jr’s appointment is that medical science is being pitted against medical science. Despite the ridicule and scorn thrown his way by some media, RFK Jr has enough independent support outside of his office towards his mission to improve the health of Americans..
He’s going to need it as challenging decades of “medical science” will not be easy for RFK Jr when federal institutions like the US Food and Drug Administration program which has survived multiple changes in government, is in need of an overhaul in RFK Jr's opinion.
The story of British scientist Professor John Yudkin should be an inspiration for the good that can come from challenging old thoughts on what constitutes healthy food.
Professor Yudkin sounded the alarm that sugar, not fat, posed the greatest harm to human health. To Professor John Yudkin’s credit, sugar has become dietary enemy number one.
Unfortunately for him, the attacks by prominent nutritionists combined with the food industry destroyed his reputation and career.
The new frontline in the battle for what constitutes healthy food continues to this day with experts like Dr. Nina Teicholz challenging the old medical establishments. It is no surprise them that her opinions suffers frequent attacks as she writes in “Regarding Controversies: Nina Teicholz”
The attacks against Dr. Teicholz’s work should come as no surprise. In an excellent article written by Ian Leslie for The Guardian, two quotes stand out.
“A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.”
“Today, nutritionists struggle to comprehend a health disaster they did not predict and may have precipitated.”
Dr.Teicholz is expected to gain prominence as an expert in what constitutes healthy food. The new focus for her work to improve the quality of food for Americans has put a bullseye in seedoils which she blames for much of what is making America sick. The solution is a return to traditional foods including meat, butter and cheese which form the foundations of iconic American meals like the burger.
Her opinions on trans fats in 2006 took over a decade for the FDA to take action. With RFK Jr in charge of public policies to make Americans healthy again, Dr Teicholz's findings against seed oils should find their way into public policy in less time but don't expect a cakewalk. The old medical schools are out with their knives to cut up Dr Teicholz's findings on seed oils and they have the support of media like the Associated Press which threw shade on RFK Jr's strong stance against the old establishments.
Are Seed Oils Healthy?
The old medical establishments includes the American Heart Association insist there’s no reason to avoid seed oils if strokes and heart disease are a concern:
Dr. Christopher Gardner, a professor of medicine at Stanford University School of Medicine in California and a nutrition scientist at the Stanford Prevention Research Center said:
"They are not to be feared.
First, while seed oils do contain high levels of omega-6 fatty acids, that's not a bad thing. Omega-6 is a polyunsaturated fat the body needs but cannot produce itself, so it must get it from foods. Polyunsaturated fats help the body reduce bad cholesterol, lowering the risk for heart disease and stroke. The American Heart Association supports the inclusion of omega-6 fatty acids as part of a healthy diet."
Dr. Gardner sounded almost apologetic in finding a reason to not fear seed oils. He uses sesame oil for a stir fry or lightly dressing a salad with sunflower oil to enjoy the health benefits of seed oils.
That is sad health advice from the American Heart Association as an old establishment for heart health. How many Americans can afford the price of sesame oil for stir frying as Dr. Gardner can or dresses salad with sunflower oil? What about deep frying a staple in the American diet, the French fries?
On the other hand, if omega 6 fatty acids are so important for health, why are “health experts” like Harvard University advocating the intake of omega 3 acids to offset the intake of omega 6? Most Americans eat more omega-6 fats than omega-3 fats, on average about 10 times more.
Think about this. If omega 6 fatty acids are indeed good for health, why should Americans consume more salmon and sardines because their intake of omega 6 fats from everyday foods threatens them with poor health?
Wouldn’t a simpler solution be to cut out omega 6 instead of having to eat more omega 3 rich foods to offset the detrimental health effects of omega 6 acids?
It is entirely possible that these “health experts” do not completely understand the causes of the health crisis in the US but are prepared nevertheless to defend what they have promoted in the past for fear of being charged with having precipitated the health disaster.
The problem then for RFK Jr should be to find solutions for healthy foods that does not require taking a pill or adding foods that are not common to the American diet. It's a nice fantasy to imagine all Americans living a Mediterranean lifestyle eating only “fruits, vegetables, beans, olive oil, some fish and chicken” while exercising regularly. Add some scavenging of common weeds in America as the Greeks do to drink as tea to beat down inflammation and the average American should live a long healthy life right?
Medical Media pushing poor medical science
What the Ikarians eat or drink has little relevance to the average American where eggs,bacon and butter are popular breakfast foods. In these days of easy access to information through the internet, it is true that influencers with no qualifications to speak on healthy foods have an undesirable influence on what healthy foods are.
The same could be said of online media which jumps on the most popular wagon to sell news stories.
Remember how eggs were reported as bad for health?
Among US adults, higher consumption of dietary cholesterol or eggs was significantly associated with higher risk of incident CVD and all-cause mortality in a dose-response manner. These results should be considered in the development of dietary guidelines and updates. JAMA Network
That faulty science has now been dismissed with new studies that eggs are good for you. The American Egg Board covered the findings with a more inclusive report on eggs and health.
But what about bacon, the staple in American breakfasts?
Having lost the arguments against cholesterol, the American Heart Association found a new victim in saturated fats for their campaigns.
A 2019 American Heart Association meta-analysis of more than 50 studies did not find a significant association between dietary cholesterol and cardiovascular risk. Where cholesterol intake did seem to increase risk, people were eating as much as three times the average amount.
Of greater concern is what usually gets served up alongside cholesterol: saturated fat. Eating lots of foods high in saturated fat increases the body’s production of low-density lipoproteins, or LDL (“bad”) cholesterol, which can build up inside the arteries, restricting blood flow to the heart and brain, heightening the chance of heart attack or stroke.
Saturated fat is a bigger culprit for raising blood cholesterol in general than dietary cholesterol,” Devries said.
Does that mean bacon with its high content of saturated fats is killing Americans with heart disease?
Yes, bacon really is killing us but don't blame the saturated fats in bacon.
According to Bee Wilson, a food journalist and author of several books, it's not the saturated fat in bacon that is causing cancers and heart attack but food additives in mass produced bacon that is the problem.
Yet here we are in 2025 and JAMA Network has published a report blaming butter and saturated fats for what ails Americans, not seedoils..
This was hurriedly republished up by the American Heart Association on their website as well as Harvard University and numerous other websites on health.
What should concern RFK Jr is how mainstream media like the Associated Press skews medical reports to ridicule his mission to make America healthy.
The AP report written by JoNel Aleccia is biased towards seedoils as analysed by Julie Mastrine for Allsides.
"The Associated Press showed strong bias in a recent piece covering the debate over seed oils. AP showed types of bias including slant, bias by viewpoint, word choice bias, spin, and bias by omission. Instead of helping readers to get a full understanding of the debate over vegetable oils, AP manipulated them into thinking seed oil critics are unfounded."
In an email response to CSPO Watch, Corey Nelson, the co-founder of Seed Oil Free Alliance suggested that reporters like JoNel Aleccia who writes for a global media powerhouse in the Associated Press should have allowed inclusivity.
“It appears a larger issue is at play, which is that journalists are unable or unwilling to consider credible opposing opinions that contradict industry-linked "experts" defending seed oils.
We often hear from seed oil advocates that there is no evidence that seed oils are harmful but there are volumes of peer-reviewed research on the topic that point to legitimate health concerns.”
AP subscribers and American consumers would benefit from more balanced coverage of the seed oil controversy, including important nuances like Corey Nelson's concerns on the smoke points of cooking oils and arachidonic acid as an inflammatory marker.
According to Zero Acres:
"But smoke points have several limitations when it comes to choosing the right oil for cooking. One significant issue is that some oils, especially those high in omega-6 polyunsaturated fats, are highly unstable and begin to break down well before they start smoking visibly. That means that some cooking oils can have relatively high smoke points but still aren't suitable for high-heat cooking.
Also, kitchens are uncontrolled environments, unlike laboratories. The smoke point of an oil is very much dependent on how you store your oil, and if the oil is subjected to heat, light, moisture, and many other environmental variables [*]. Therefore, compared to accurate smoke points measured by scientists, the results you experience in your kitchen can vary."
The smoke point of high omega 6 oils is a problem Harvard should have addressed in assuring its readers that there is no need to avoid omega 6 high seed oils by saying A salad dressing made with one tablespoon of safflower oil gives you 9 grams of omega-6 fats.
What’s up with this promotion of seed oils as a salad dressing? Can you cook at home with seed oils without worry about chronic diseases?
Public health policy which RFK Jr is in charge of must look at what the average American prefers in their food, what they can afford and what is being fed to them by the big food companies.
Old Medical Science vs New Medical Science vs What We Know Now
Academics like Chris Gardner or Professor Sarah Berry from King’s College London continue to skirt the issue with dismissive "expert opinions."
Dr. Sarah Berry made light of pro-butter campaigners by dismissing them as “butter bros” in a comment published by the Science Media Center.
There’s no doubt she was pleased by the new study which seemed to support her small study of nineteen healthy male subjects on the problem of re-using oils from deep frying.
Corey Nelson found exceptions to the study which the doctor must have missed.
“I noticed that the highest butter intake group were tobacco smokers at more than twice the rate of the lowest group (also noted in the Science Media Centre article linked). Also that margarine blend was included in the butter category.”
On top of participants in the Butter and plant-based oils study that smoked tobacco, Corey found an issue with the absence of Cooking Oil Fumes (COF) as a factor in cancer and cardiovascular diseases.
"Cooking oil fumes are certainly a concern, and there is some evidence that polyunsaturated fats produce higher levels of polycyclic aromatic hydrocarbons (PAHs), both in fumes and in food, compared to other fatty acids. I think it's somewhat tangential to the health effects of ingesting said oils, though, because the fumes can be mediated at least in part by proper ventilation systems. I have advocated for tobacco-style warning labels in the US for restaurants that cook with high-polyunsaturated (seed oils) at high heats and/or reuse the cooking oil."
Corey’s concern about COFs is not new science.
A meta-analysis conducted to evaluate the relationship between cooking oil fume exposure and lung cancer among Chinese nonsmoking women found that long-term cooking oil fume exposure significantly increases the risk of lung cancer among Chinese nonsmoking women.
But how would the average American know which cooking oil throws out more carcinogenic fumes?
Chemical engineer Qua Kiat Seng from Monash University in Malaysia has a simple test. Bake your foods with seedoils in a clean oven and check for an oily smell in the house plus oil coating in the oven. Then bake with butter under the same conditions..
The fumes from seed oils are guaranteed to permeate the house while coating the oven with a layer of grease. That is cooking oil fumes.
US restaurants can protect their kitchen staffers and the air quality around their locations with proper ventilation systems as Corey Nelson suggested but what of the seed oils ingested?
The French paradox which Ancel Keys could not explain has seen many apologists looking for answers in “oh maybe its because the French drink red wine to offset their saturated fat intake” to the absurd accusation that French authorities underreported mortalities due to saturated fat intakes.
What is not absurd is the findings of SL Malhotra on the diets and lifestyles of over a million railway workers in India which concluded that:
A survey of the incidence of acute myocardial infarction and the dietary behaviour in railway populations in India showed that the disease was 7 times more common among South Indians as compared with the Punjabis in the North, even though the fat intake of Punjabis was 8-19 times more than that of South Indians, and was chiefly of animal origin.
SL Malhotra’s findings were supported in this 2016 meta analysis on butter and cardiovascular diseases
Butter consumption and incident CVD (total CVD, CHD, or stroke) was investigated in 5 studies from 4 cohorts, including 175,612 participants and 9,783 cases of any CVD. When pooled, butter intake was not significantly associated with CVD
Thank you for having read this commentary up to this point. It's a complex issue that is best understood if you listen to your body to find out if a return to traditional foods works better for you.
For a better understanding of seed oils and why some folks like Dr. Sarah Berry promote seed oils, do enjoy this article by Zoe Harcombe on the misinformation on seed oils.
In the meantime, the monstrous task of making Americans healthy again has landed on the shoulders of Dr. Marty Makary, a surgical oncologist and health policy researcher from John Hopkins University who was confirmed this week as the next commissioner of the U.S. Food and Drug Administration (FDA) in a bipartisan vote.

Omega-6 Fatty Acid Promotes the Growth of an Aggressive Type of Breast Cancer
Linoleic acid, an omega-6 fatty acid found in seed oils such as soybean and safflower oil, and animal products including pork and eggs, specifically enhances the growth of the hard-to-treat “triple negative” breast cancer subtype, according to a preclinical study led by Weill Cornell Medicine investigators. The discovery could lead to new dietary and pharmaceutical strategies against breast and other cancers.
In the study, published March 14 in Science, the researchers found that linoleic acid can activate a major growth pathway in tumor cells by binding to a protein called FABP5. Comparing breast cancer subtypes, the team observed that this growth pathway activation occurs in triple-negative tumor cells, where FABP5 is particularly abundant, but not in other hormone-sensitive subtypes. In a mouse model of triple-negative breast cancer, a diet high in linoleic acid enhanced tumor growth.
“This discovery helps clarify the relationship between dietary fats and cancer, and sheds light on how to define which patients might benefit the most from specific nutritional recommendations in a personalized manner,” said study senior author Dr. John Blenis, the Anna-Maria and Stephen Kellen Professor of Cancer Research in the Department of Pharmacology and a member of the Sandra and Edward Meyer Cancer Center at Weill Cornell Medicine.
