Question: I was wondering why it is a widely believed that saturated fats are bad for you, when humans have evolved to eat animal fats, and they provide a large number of uses in the body?
Answer: Early humans evolved on diets very low in saturated fats. They didnt eat fatty domesticated animals like cows, lambs, and pigs. They ate wild game, which is extremely lean and the ratio of saturated fats to omega-3s is the opposite of domesticated animals. Saturated fats are not essential nutrients. In fact, if humans never ate another gram of saturated fats it wouldnt affect health at all.
However, the omega-3s, especially the omega-3s in fatty fish, are critical to blood vessel, nerve, and occular tissue function and structure; omega-3s are not made by the body, so they must be obtained from diet.
Numerous health conditions, including dementia, depression, and possibly even Alzheimer's and heart disease, are now being attributed to low omega-3 intake.
