Research argues that heart health guidelines on saturated fat are outdated
Medical Xpress / Ateneo de Manila University / Nutrients ^ | Oct. 22, 2024 | Mary T. Newport et al

Warnings against saturated fat on heart health need to be revisited as flaws were revealed in the seminal 1950s studies on which these warnings were based, according to research.

In 1953, spurred by an apparent surge in heart disease in the US, physiologist Ancel Keys published a study that introduced the "lipid-heart hypothesis." He claimed without evidence that high saturated fat and cholesterol in the diet raise cholesterol levels in the blood and contribute to heart disease.

Newport and Dayrit pointed out that Keys erroneously conflated the saturated fats found in meat and dairy with the harmful industrial trans-fats commonly used in margarine and shortening. Keys also included coconut oil in the warning.

They argue that this misunderstanding has led to flawed dietary recommendations, including a disproportionate focus on heart disease at the expense of research into the role of trans-fats in cancer, obesity, and other metabolic disorders. These conditions have been steadily on the rise in the decades since Keys published his findings.

"Numerous observational, epidemiological, interventional, and autopsy studies have failed to validate the Keys equation and the lipid-heart hypothesis. Nevertheless, these have been the cornerstone of national and international dietary guidelines," the researchers said.

The study highlights that trans-fats, commonly found in processed foods, are strongly linked to heart disease. These industrial fats were widely consumed during the twentieth century but ignored in dietary guidelines that were based on Keys' claims.

It also critiques the unregulated promotion of polyunsaturated fats—specifically linoleic acid, commonly found in soybean oil and other vegetable oils—which can lead to an imbalance in omega-6 and omega-3 fatty acids and increase the risk of chronic inflammation and other health issues.

“My mom, too. She had a crock on the back of the stove for bacon grease. Never refrigerated.”

Same here, I grew up on a family ranch. Great Grandma and Grandma did the same.

While it was a little past time for Great Grandma, Grandma was still climbing in the saddle and riding horseback to move stock or go hunting deer from horseback when she was 78 years old...

I keep a jar of bacon grease to this day. I use it sometimes, more to flavor an item when I don’t have bacon on hand. I use it especially for fried green tomatoes along with a little butter.

Hitler, Mao, Stalin and Putin are responsible for 30 million, 60 million, 50 million and about half a million. There aren’t that many deaths from all causes of heart disease, including cigarettes.

Side question: I’m so disgusted at all the neo-Soviet Putin fans around Free Republic, but you’re not of the bizarrely warped opinion that Putin ranks up there or even beyond Hitler, Mao and Stalin, are you?

To give credit where credit is due... I was quoting Freee-dame from her first comment about the bacon grease. I appreciate her bringing this up! Because we never fell for the hype and still do this as a family.

I’ve read where people rave at about how wonderful popcorn is with the bacon grease for flavoring. Have never tried that. Will stick with butter and Parmesan cheese.

Re cholesterol, read Wheat Belly by Wm Davis, MD. He demonstrates that wheat is the actual thing loading your arteries with cholesterol.
~~~~~

Dr. Alessio Fasano discovered zonulin, the human gut enzyme which combines the actions of both wheat and fructose-grown gut bacteria to make the small intestine lining porous. Wheat AND fructose are the culprits, so add the work of Dr. Robert Lustig and his book “Fat Chance: The Bitter Truth About Sugar” (2012) for a complete diet guide to avoiding heart disease.

The only difference between saturated fats and unsaturated fats is the temperature at which solid fat melts. Chemically the body makes no distinction between the two.

“This is something to be aware of considering the prevalence of many high-protein diets.” Eating over 35% protein would be VERY rare. Most people left on their own won’t eat over 20%. It would take real work to overeat protein - unless one is using protein supplements in a dumb attempt to build huge muscles.

“Carbohydrate intake: 45 to 65 percent of total calories” is just DUMB! I don’t care WHO recommends it. It is just DUMB! All digestible carbohydrate turns into glucose. That is what our body converts it to.

So what kind of stupidity leads to a recommendation to eat up to 65% of our calories as SUGAR?

Well...this IS interesting..

“Newport and Dayrit pointed out that Keys erroneously conflated the saturated fats found in meat and dairy with the harmful industrial trans-fats commonly used in margarine and shortening. Keys also included coconut oil in the warning.”

The deaths from cardiovascular disease in America run around 900K/year. Multiply that by 60 years and you get over 50 million - although, of course, everyone is going to die from something.

I find 700K/yr. Of course, with a rapidly growing elderly population, that’s far higher than would have been average over the past 60 years. So 500K/yr. Times 60 years, that’s 30 million people. So that *is* as I’ve said less than Hitler and about half of Mao.

And, of course, the main point is that it’s absolute stupidity to blame every heart-related death on the one guy. Maybe, MAYBE, you could reduce heart-related deaths by about 20% if everyone adopted a healthier diet.

Oh yeah, and you’ve completely misinterpreted the main point, which is not that this guy’s bad advice caused so many deaths, but that his bad advice simply called for unnecessary reductions in pleasurable food. Reconsidering the facts, there was no need to abstain from bacon, but no-one ever said that eating more bacon would prevent heart disease.

“Eating over 35% protein would be VERY rare. Most people left on their own won’t eat over 20%. It would take real work to overeat protein.”

It is a ratio of balance. If you eat less fat calories it raises the percentage of protein in the ratio. In other words, if you cut out all meat fat calories you are then going to be far too high in protein levels for the amount of food consumed.

Like the Rabbit issue. In a survival situation eating lean rabbit without also cooking the organs and consuming them and the broth also will poison you to death. The organs have the needed balance of meat fat calories to offset this ratio issue.

“If you eat less fat calories it raises the percentage of protein in the ratio.”

No. In almost every case, people who reduce fat increase CARBS. If you cut fat, you increase sugar (carbs). People who are not intentionally trying to eat as much protein as possible won’t go much over 20% protein. Sometimes hit 25%, but our bodies know they don’t need that much protein and tell us to stop.

The variables - unless one is a bodybuilder - are carbs and fat.

“In a survival situation eating lean rabbit without also cooking the organs and consuming them...” In a survival situation, you do what you have to do. No one is planning on doing that for more than a few days. Maybe weeks if lost in the wilderness. Totally irrelevant to any normal human.

I eat a near carnivore diet. Not quite because I prefer to add around 40-50 grams of carbs. So I eat a “high fat diet”.

And consider 85% hamburger: 1 pound of raw hamburger has 84 grams of protein. Out of 454 grams total - 18%. 18% and that is lean hamburger. A 100g serving of NY Strip steak has 23 grams of protein - 23%.

The garbage Dietary Guidelines for Americans recommends your CALORIE ratio should be 45–65% carbs, 20–35% fat, and 10–35% protein. But a gram of fat has twice the calories of protein or carbs. 85% lean hamburger, cooked, provides 117 calories from fat and 96 from protein - more fat than protein. You pretty much CANNOT “cut out all meat fat calories”. It doesn’t happen.

Yes it does... If you have 10 ounces of meat, 50% fat and 50% protein that is a 50/50 ratio. If you have ten ounces of meat and only 5% of that is fat, then the protein ratio is 95% in that “same amount of meat”.

This negates the idea that it is rare to be ingesting too much protein. Right there is your offset that puts you in the danger zone for the same amount of meat consumed. If you continue to eat this ratio over time without additional fat added you are in trouble.

Point is this info is honest, the health industry recommendations of no meat, or low fat diets is harmful and is “keeping” folks sick.
