Are Lipids (fats) bad for human health?
No, some fats are harmful to human health, such as saturated FA, trans-fat (mainly from dehydrogenated) etc.; but some fats are necessary to human health, such as omega-3 (ALA, DHA, EPA) and omega-6 (GLA, ARA). A deficiency in either progressively results in poor health. Like other essential nutrients, the human body cannot function without these EFAs in the diet. EFAs function as building blocks for membranes of every cell in the body. They also produce “prostaglandin families,” which are hormone-like substances necessary for energy metabolism and cardiovascular and immune health. Brain and nerve tissue consist of over 50% EFAs! See the Benefits of Omega-3 and 6 for more information.
