Definition:
ALA, or alpha-linolenic acid, is a type of omega-3, a polyunsaturated fat found in supplements and in some foods -- mainly walnuts, flaxseed, and certain vegetable oils. ALA obtained through diet can be converted to other omega-3 fatty acids, such as DHA and EPA. However, this is a very small conversion.
Unlike positive studies showing promotion of heart health with EPA and DHA, studies involving ALA have been conflicting. Some studies have shown that ALA can slightly lower lipids and heart disease risk in individuals already diagnosed with hyperlipidemia and coronary heart disease, respectively, whereas others studies have not been able to establish this relationship.
