Fatty acids are the basic building blocks of which fats and oils are composed. Contrary to popular belief, the body does need fat, but it must be the right kind. The fatty acids that are necessary for health and that cannot be made by the body are called essential fatty acids (EFAs). EFAs, which play a critical role in many aspects of health, from the condition of your skin to your hormones, can only be obtained from the diet.
The hormone modulating effects of prostaglandins, hormone-like substances, derived from essential fatty acids makes them particularly important if optimal hormonal health is to be achieved.
