Rockefeller Foundation spent heavily to determine a diet that would weaken the population. Many studies (private) were conducted to find and promote foods that reduce testosterone and promote obesity. They succeeded.
All hormones require cholesterol as building blocks. Drugs like the statin class block the mevalonate pathway to reduce cholesterol.
Cholesterol is vital and necessary.
150 years ago humans consumed almost entirely saturated and monounsaturated fats. Polyunsaturated fats (PUFA) were only about 1 to 2% of the diet. Seed oils (cotton, then corn and soybean) are very high in polyunsaturated fats.
These fats are fragile. Saturated fats contain no double bonds. They are a straight carbon chain all terminated with hydrogens. They do not oxidize or go rancid.
Polyunsaturated fats have multiple double bonds and easily oxidize and rancidify. When our bodies make structures with these fragile fatty acids the whole organism becomes fragile. Every cell has a lipid (fatty acid) membrane. Every mitochondria has a inner/outer membrane. When these vital membranes are made from fragile, easily oxidized fatty acids they are susceptible to disfunction (ie cardiolipin disfunction within mitochondria).
On a macro scale you can test the effect of limiting polyunsaturated fats (below 4% of total fats) on yourself. After several months you will not be vulnerable to sunburn for several hours. If your skin can improve its resiliency to sunburn how will other vital structures within your body react?
We are designed to consume saturated and monounsaturated fats, those that are found in natural human food. When we eat calories to excess we store them as saturated fats. We also have an enzyme(SCD1) to transform some saturated to monounsaturated fats. We have no ability to create polyunsaturated fat at all. Native humans only ate trace amounts but modern humans routinely have fat stores that are 30% or more PUFA.
If there is any single dietary change that will impact your health it is eliminating PUFA from your diet. Unfortunately, modern pork and chicken (because they are monogastric animals) have high PUFA because of their seed oil and grain diets.
Eat steak and ruminant organs and prosper.
Thanks for taking the time to write this. Interesting point about the pork/chicken versus ruminants. Any resources to look at about the Rockefeller Foundation researching diet influence?
