Eat the fats humans have been eating for the longest.
How long have we been eating each fat??
Animal Fats (2.5 million years)
Butter (6000 yrs)
Coconut Oil (1000's of yrs)
Olive Oil (1000's of yrs)
Avocado Oil (1000's of yrs)

AVOID
Soybean oil: ~100 years
Corn oil: ~130 years
Canola oil: ~50 years
Peanut oil: ~200 years
Sunflower oil: ~200 years
Cottonseed oil: ~140 years
NO meaningful evolution of human physiology has occurred in the last 200 years, we are not adapted to seed oils. They are an evolutionary mismatch.
