Essential fatty acids
A group of acids now known to be of significant nutritional importance, the lack of which is believed to contribute to a very wide range of common Western ills, including arthritis, skin diseases, menstrual and menopausal problems, and heart disease. This group includes gamma-linolenic acid (GLA) and eicosapentanoeic acid (EPA) found in fish oils. A number of EFAs can be metabolized in the body from cis-linoleic acid found in cold-pressed seed oils and leafy vegetables. Gamma-linolenic acid is found in evening primrose oil, borage oil, and blackcurrant oil. Alpha-linoleic acid is found in significant amounts in linseed, hemp seed, and pumpkin seed oils; lesser amounts are found in walnut and soy bean oils.
