If there were an elixir of life it would probably contain one of the polyunsaturated fatty acids (PUFA). Specifically, omega-3 has exhibited the ability to prevent heart disease, lower blood pressure, protect post-menopausal women against cancer, fend off depression and improve love life. Although the benefits of omega-6 fatty acids are less touted, studies do show the ratio of omega-3 to omega-6 is important to disease prevention.
Research is also continuing to delve into the health advantages of other nutritional lipids such as conjugated linoleic acid (CLA), which may play a role in diets for those concerned with weight loss or diabetes. As companies strive to attract consumers, decisions on how to formulate and market nutritionally enhanced products will continue to be critical.
