"In 1962 a South African doctor named A. Gerald Shaper set out into the African bush to study the heart health of the Samburu tribe of Northern Kenya. Depending on the season Dr. Shaper found that young Samburu males consumed between 2-7 liters of milk every day which could contain as much as a pound of butterfat or more. At times they would add 2-4 pounds of meat to their daily consumption which drove consumed cholesterol sky high. Which of course doctors will tell you will cause heart attacks.
A few years later Doctor and Professor George V. Mann traveled to Africa to study the Masai men who he had heard ate nothing but meat, blood & milk and disdained vegetables as womanly food. Of course Dr. Mann’s colleagues back in the States had decided that animal fats cause heart disease. So Dr. Mann and his team from Vanderbilt University brought along a portable lab to investigate the health and diet of the Masai tribesman.
Professor Mann found the Masai tribesman also consumed between 3-5 liters of milk per day. In the dry season when milk ran low they would mix in cows blood. They also enjoyed lots of meat including beef, lamb, and goat and on party days or market days they might eat as much as 4-10 pounds of meat.
In both cases fat was 60 percent of calories, being critter based that means it was mostly saturated fats. The young men again in both cases disdained vegetables scorning them as womanly food.
And what they found was the blood pressure and weight of these meat eating dudes was about half of the average American at that time. These numbers also didn’t rise with age. Dr. Shaper said these findings hit him hard, he realized that worsening health was not automatic as you age which is what everyone assumed then and now.
A review of 26 studies of small ethnically homogeneous hunter gatherer groups who were living in primitive conditions and eating an ancestral diet (e.g. they are eating what their people were eating hundreds of years ago) an increase of blood pressure was not a normal part of aging and just to keep driving this point home all of the metabolic syndrome diseases are of a piece so the lack of high blood pressure is really an indication that they weren’t suffering the metabolic diseases."
@Escoffier Ancel Keys is one of the greatest quacks in US history, and is directly responsible for the atrocity that is the current American diet. I was going to do an effortpoast but it turns out someone already beat me to it, with all the graphs and papers linked. Read this, you will like it (ignore the author's self-shilling, his data checks out)
@TrevorGoodchild Any thoughts or commentary as someone who has infinitely more knowledge on the medical side? I'm just a dumb old chef who likes to read.
@TrevorGoodchild@Escoffier >Hydrogenation created “trans-fats” which studies indicate doubled the risk of heart disease for every 2% consumed . Meanwhile, American’s were consuming upwards of 10kg a day. This should be >Hydrogenation created “trans-fats” which studies indicate doubled the risk of heart disease for every 2% increase in trans fat consumed. Meanwhile, American diet increased trans fat consumption by 10% over the indicated period.
A few other phrasings made it hard to read for me since I got dyslexia
@epictittus@Escoffier It's not very polished but he did an excellent job of getting all the critical papers, graphs, and bullet points in one short-form piece. His debunking of Ancel Keys' 'Seven Countries' study in particular is very short, sweet and layman-accessible
@TrevorGoodchild@epictittus@Escoffier Keys shows a common issue: guy with absolute certanity appears, says that if you make mild change that something you fear and seems unfixable will be gone. Classic silver bullet. So Keys should be called a fake werewolf hunter.
@Escoffier@TrevorGoodchild I have no evidence for this, but my intuition is that the process of making trans fats from oil is random by nature, and produces toxic byproducts. As to why those byproducts are bad.... trans fat specifically is way more rigid, stable and difficult to digest, while at the same time causing problems wherever it deposits. For example if it deposits in a cell membrane, it makes the membrane more rigid (like a heat shock protein) and less permeable. If this is the membrane of an arterial cell which has to be permeable in a specific way as well as contract/expand... it can cause a cell to break apart, which causes platelets to accumulate there, which leads to plaque.
@epictittus@TrevorGoodchild I was working in kitchens when they transitioned from lovely wonderful tallow to the various awful seed oils and then the steps they had to take to make them palatable. Bit of a nightmare.
