I wonder how well Eskimos would do on a meat free diet?
Who here has a background in physical anthropology and biochemistry and can actually understand the implications of these diets beyond a surface/word of mouth level?
Almost everything we consider food can have negative consequences if consumed in excess. Genetics play a big part of what a health diet is for each individual.
I cant/no one can say what is an optimum human diet, and not only because it varies for individuals, i can say that the documentary is not based on strong science.
They cite poorly conducted, non-repeated experiments many times such as with the study done on rats fed casein protein, the low protein rats died prematurely, perhaps not allowing cancer to manifest and in part to their low protein diets. There were other problems with this one as well.
They cited the study on monkeys without even understanding the results;
“Monkeys on low protein diet surviving for 90 weeks or more show foci of preneoplastic lesions, whereas those on high protein diet reveal no such alterations at the corresponding time interval…It appears that in the simian model used by us, the liver injury caused by [aflatoxin] is accentuated by simultaneous restriction of dietary protein and in animals on such combined regimen preneoplastic lesions appear around 90 weeks of experiment. These observations suggest a synergism between protein calorie malnutrition and aflatoxin induced hepatocarcinogenesis and may explain the higher incidence of hepatocellular carcinoma in certain areas of the world where contamination of foods with aflatoxin and malnutrition are prevalent.”
The doc is bullshit but some of what they are saying may not be, hard to separate when they purposely mislead the audience to suite their agenda. (either that or none of them can understand scientific publications)
I could go on. You can be healthy on a wide variety of diets. The way we raise most of our meat is not environmentally ethical, that in my eyes is a much greater concern than the health consequences of reasonably consuming it based on my understanding of biology.
We dont fucking know what to eat, probably because we want to believe there is one optimum diet for all of us.
