For many years, the dominant narrative insisted that saturated fats was lethal — despite the fact that the precise knowledge by no means proved it. As a consequence, the well being recommendation shifted towards seed oils and processed margarine, which quietly ushered in new well being issues, from metabolic illness to weight problems and inflammatory problems — all whereas the unique speculation remained unchallenged by mainstream drugs.
Now, for the primary time, high-ranking officers are overtly criticizing these outdated pointers. So, should you nonetheless imagine that butter, beef, and full-fat cheese clog your arteries and are damaging your well being, it’s time to relearn all the things about these fats sources.
New FDA Commissioner Aims to End the 70-Year War on Saturated Fat
On July 14, 2025, Dr. Marty Makary, the newly appointed U.S Food and Drug Administration (FDA) commissioner, together with Sec. Robert F. Kennedy, Jr. of the Department of Health and Human Services and Sec. Brooke Rollins of the Department of Agriculture, held a press convention addressing their plans to considerably overhaul the U.S. dietary pointers.1
• One of the first areas that they are going to work on is revising the rules on saturated fats — During the press convention, Makary highlighted how the adjustments to the meals pointers will probably be made based mostly on scientific findings. He mentions that the demonization of saturated fats started with a flawed examine — the Seven Countries Study by Ancel Keys.
• Why the Seven Countries Study was considerably flawed — The examine, which began in 1958 and continued till 1983, explored the guts well being of various populations in a number of distinguished Western nations. According to Keys’ speculation, there’s a important hyperlink between saturated fats and coronary heart illness. When he printed his knowledge, it confirmed good correlations between heart problems and the dietary consumption of fats.2
However, there was only one drawback with the analysis — Keys cherry-picked the information. He selectively selected the nations that match his speculation whereas ignoring knowledge from 16 different nations that went towards his suggestions.3 Had he chosen a distinct set of nations, the information would have been the other — that rising the % of energy from fats truly reduces the variety of deaths from coronary coronary heart illness.
• Despite the methodological flaws in his knowledge, the medical group accepted Keys’ examine — This led to the promulgation of “low-fat, low-cholesterol” meals as wholesome. Butter, coconut oil, crimson meat, dairy, and eggs have been all shunned, whereas polyunsaturated fat (PUFs) like margarine, vegetable oils, and shortening have been popularized.
• The medical institution “locked arms and walked off a cliff together” — This was how Makary described the shift from saturated fats to polyunsaturated fats — principally, the well being group again then took a glance and determined that Keys’s examine was gospel reality — regardless of many consultants contesting his speculation and plenty of research4,5 exhibiting the other.
“The medical establishment started with a robust debate in the New England Journal of Medicine among academics of the National Academy. But that debate ended in the 1970s because there was groupthink,” Makary mentioned.
“Well, that dogma still lives large and you see remnants of it in the food guidelines that we are now revising. So, we’re going to ensure that the new guidelines are based on science and not medical dogma.”6
To see the tide lastly turning and the federal government well being businesses taking the lead on these monumental adjustments is one thing I applaud. Over the previous couple of many years, I’ve printed numerous articles concerning the flaws in Keys’ examine — and why saturated fat are to not be feared, as they’re truly integral to your well being.
Documentary Exposed the Flaws and Received Fierce Backlash
Just like me, Maryanne Demasi, Ph.D., has been talking out concerning the faulty demonization of saturated fats for a very long time. Several years in the past, I wrote a couple of two-part documentary she produced known as “Heart of the Matter,” which aired on the Australian Broadcasting Corporation’s present (ABC) Catalyst in 2014. I used to be extraordinarily impressed by the movie, because it did a superb job of exposing the ldl cholesterol/saturated fats myths and its financially hyperlinks to cholesterol-lowering medication known as statins.
In her current Substack submit, Demasi detailed the extreme backlash she acquired after she launched the documentary, and her ideas on these current developments from the U.S. authorities businesses. “It was a stunning moment — not because the criticism was new, but because it was coming from someone in an official position to do something,” she mentioned.7
• “Heart of the Matter” centered on two major factors — The first half examined the demonization of saturated fats, whereas the second half dwelled on the widespread use of statins.
“The medical dogma was firmly entrenched: saturated fat raised cholesterol, and cholesterol caused heart disease. But the science behind it was shaky — built on cherry-picked data and upheld more by consensus than by critical evaluation,” she mentioned.
• The findings have been supported by a few of the high consultants within the area of cardiovascular well being — Among the interviewees featured have been Dr. Michael Eades, an early advocate for low-carb, high-fat diets, cardiologists Dr. Stephen Sinatra and Dr. Ernest Curtis, nutritionist Dr. Jonny Bowden, and science journalist Gary Taubes. All of those consultants voiced their considerations concerning the warnings towards saturated fats. Demasi mentioned:
“Eades, as an example, highlighted the absurdity of the prevailing narrative: ‘You very seldom see the words ‘saturated fat’ within the public press once they’re not related to artery clogging. So it’s prefer it’s all one time period — ‘artery clogging saturated fats.’’
And Taubes, creator of Good Calories Bad Calories, identified for his meticulous dismantling of food plan dogma, minimize to the core: ‘There’s no compelling proof that saturated fats is concerned in coronary heart illness.’”
To current either side equally, the documentary additionally featured consultants who vigorously defended the warnings towards saturated fats. Robert Grenfell, the director of the National Heart Foundation, and Professor David Sullivan, a heart specialist, shared their ideas within the movie.
• Still, the backlash was overwhelming — Demasi describes it as “immediate, vicious, and unrelenting.” The media not solely turned towards her, however in addition they went towards the consultants who challenged the saturated fats dogma. And despite the fact that no factual inaccuracies have been discovered, ABC nonetheless pulled each episodes from its web site.
Numerous Experts Have Sounded the Alarm on Keys’ Flawed Research
The incontrovertible fact that Ancel Keys’ speculation was purely observational and couldn’t set up causation has lengthy been raised by many well being consultants — even through the first years when the Seven Countries examine got here out. According to Demasi, John Yudkin, a British physiologist and nutritionist warned that sugar, not fats, was the true reason behind coronary heart illness. However, he was mocked and marginalized by Keys, who thought of Yudkin his fiercest opponent.8
Yudkin was the primary, however he wasn’t the one one — quite a few researchers like Uffe Ravnskov and Malcolm Kendrick, additionally publicly challenged Keys’ speculation, co-authoring publications that uncovered the issues of this examine. Many others quickly adopted, which Demasi outlined in her weblog submit.
• “Saturated fat is not the major issue” — In 2013, heart specialist Dr. Aseem Malhotra printed a commentary on the BMJ, saying that the flawed recommendation from Keys brought about folks to aggressively decrease ldl cholesterol — which can have led to larger charges of coronary heart illness.
“The mantra that saturated fat must be removed to reduce the risk of cardiovascular disease has dominated dietary advice and guidelines for almost four decades. Yet scientific evidence shows that this advice has, paradoxically, increased our cardiovascular risks,” Malhotra wrote.9
• “The Big Fat Surprise” — Nina Teicholz wrote her best-selling exposè in 2014,10 which helped carry the problem to public consideration. Her deeply researched guide challenged the standard knowledge on dietary fat, particularly saturated fats. “Teicholz documented how weak science, political pressure, and food industry lobbying created a false consensus that demonised fat and distorted public health policy,” Demasi remarked.11
• “Re-evaluation of the traditional diet-heart hypothesis” — In 2016, a gaggle of researchers printed a landmark re-analysis of the Minnesota Coronary Experiment within the BMJ, to judge the accuracy of Keys speculation. They discovered that when saturated fats was changed with linoleic acid (LA) from vegetable oils, levels of cholesterol have been lowered — however paradoxically led to a rise in deaths, notably from heart problems.
“Findings from the Minnesota Coronary Experiment add to growing evidence that incomplete publication has contributed to overestimation of the benefits of replacing saturated fat with vegetable oils rich in linoleic acid,” the researchers concluded.12
The Cholesterol Hypothesis Is a ‘Professional Litmus Test’
The plans to overtake the U.S. dietary pointers give hope to many researchers like Demasi, who’ve lengthy raised their considerations about this flawed science — however have been ostracized because of this.
“For the primary time, actual change could also be coming — not from the margins, however from the very high of the U.S. well being institution…
It’s taken many years. The ldl cholesterol speculation wasn’t only a scientific declare — it turned knowledgeable litmus take a look at. To problem it was to threat your funding, your profession, your credibility. Many of us paid that value. Even now, entrenched pursuits stay,” she wrote.
• But why was the parable allowed to persist within the first place? Apparently, it’s all due to the meals and drug {industry}. In a video podcast, Dr. Paul Saladino and Teicholz mentioned how the low-fat, low-cholesterol fantasy quickly led to dramatic adjustments within the meals and drug industries — adjustments which have confirmed to be extremely profitable, financially talking.13
• Acknowledging that saturated fats is wholesome means to relinquish huge {industry} income — The Big Food {industry} is raking in tens of millions of {dollars} from the low-fat and low-cholesterol (but extremely processed) meals, together with industrial vegetable oils. To admit that these “healthier options” are literally decimating public well being would result in nice monetary losses. The wholesome different is actual meals — nonetheless, there is no huge {industry} income to be constituted of that.
• Moreover, statin gross sales and different Big Pharma revenue areas would undergo — The entire level of prescribing statins was to decrease ldl cholesterol, but when the notion that ldl cholesterol is dangerous can be overturned, then what can be the purpose of taking these medication?
Personally, I imagine that statins are among the many most overprescribed — and pointless — drugs in the marketplace right this moment. Not solely do the harms far outweigh the advantages, however they’re additionally ineffective. In reality, in “Heart of the Matter,” the consultants repeatedly say that statins solely lengthen a life by just a few days and, regardless of their hype and recognition, are shockingly ineffective for all however just a few folks. Learn extra about these medication in my article, “Statins Do More Harm Than Good.”
Vegetable Oils Undermine Your Health
Perhaps the worst impact of the demonization of saturated fat — together with butter, tallow, lard, and coconut oil — is that it paved the way in which for vegetable oils like soybean, canola, and corn oil, that are loaded with linoleic acid, a polyunsaturated fats (PUF), to change into a regular a part of the fashionable food plan.
Today, Americans eat LA at ranges that may have been unimaginable a century in the past. In the 1860s, we solely consumed 2 grams of LA per day; that quantity has now elevated to shut to 30 grams per day for most individuals. It now makes up 15% to 25% of a typical American’s caloric consumption. And the price of this overload? Your cells change into extra susceptible to oxidative stress.
• Excessive LA causes your mitochondria to interrupt down — The mitochondria, that are the powerhouse of your cells, accountable for creating power, are considerably broken due to this fats. LA transforms into oxidized linoleic acid metabolites (OXLAMs), harmful byproducts that harm DNA, disrupt power manufacturing, and drive continual irritation all through your physique.
OXLAMs have been linked to not simply coronary heart illness, however almost each continual illness now plaguing the developed world, akin to weight problems, Type 2 diabetes, and even neurodegeneration.
• LA stays in your physique for years — You don’t merely remove it; as a substitute, it LA embeds in your physique fats, the place it continues to inflict harm even after you clear up your food plan. I like to recommend studying my paper printed in Nutrients to know how this occurs — and how one can reverse it. My paper additionally expounds on the long-term organic results of this metabolic disruptor.
• Unfortunately, LA is rampant within the meals provide — Even should you cease utilizing seed oils, or don’t eat fried meals and quick meals, you could possibly nonetheless find yourself consuming massive quantities of LA primarily as a result of it is cleverly hidden in so many packaged merchandise the place you’d least count on it.
Lowering your consumption of business seed oils begins with figuring out the place they conceal. I like to recommend downloading my Health Coach app, which will probably be out quickly. It has a singular characteristic known as Seed Oil Sleuth™, which is able to assist determine each hidden supply of seed oils in your meals. It additionally calculates your day by day LA consumption to the closest tenth of a gram. Just scan the QR code beneath to affix the early-access listing to the app.
Saturated Fat Is Not the Enemy — Misinformation Is
So how do you undo the harm of 70 years of misguided well being coverage? The excellent news is there are methods to assist revert the harm, and it begins by specializing in the foundation trigger — eradicating industrial seed oils loaded with linoleic acid (LA). Carefully learn labels, even in so-called “healthy” snacks; bear in mind, these dangerous fat are lurking in all places.
Once you’ve cleaned up all of the unhealthy fat in your food plan, begin rebuilding your well being with saturated fat from clear animal sources, that are secure and nourishing. Choose wholesome choices like grass fed butter, ghee, beef tallow, and coconut oil, which help your mitochondria, don’t oxidize simply, and supply regular power. For extra wholesome way of life methods to remove LA out of your food plan, I like to recommend studying “Linoleic Acid, Mitochondria, Gut Microbiome, and Metabolic Health — A Mechanistic Review.”
These new developments within the U.S. meals provide are actually a breath of contemporary air, and if Makary and others who’re a part of the “Make America Healthy Again” (MAHA) marketing campaign comply with by means of, we might lastly get dietary pointers that replicate organic reality, not {industry} agendas. As Demasi concludes:
“[W]e may finally be seeing the collapse of one of the most destructive public health myths in modern history … For those of us who’ve waited decades, it’s not vindication we want (although that would be nice) — it’s change.”14
