Human diets likely evolved to contain about 2% polyunsaturated fatty acids, compared to current intakes of 10-20% or more.

“traditionally if you look at the hunter-gatherer diet and you look at what humans would have eaten evolutionarily the amount of polyunsaturated fat in wild animals is very low it's estimated that treat that evolutionarily in our predecessors we probably had two percent polyunsaturated fatty acid in our diet and that right now we're estimating 10 and 20 for some people of their fat is polyunsaturated”

“in general I would say all humans should have Pua as less than 3% of energy talked about that in the past that's consistent what we see in Hunter gather populations the hza the UNG Etc less than 3% of their energy comes from puas”

“Historically, ancestrally polyunsaturated fatty acids were in short supply. We don't have seed oils before a 100 years ago. And nuts are very, very rare, seasonal, and very hard to obtain. And so consumption of polyunsaturated fatty acids by indigenous cultures is 1 to 2% max of their calories. Mhm. >> Today we're upwards of 10 to 15%.”
