See note to Omega 6 FAs about inadequate conversion of linoleic to linolenic acid by the body. The essential fatty acids from which the healthy body working at optimum efficiency should produce Omega 3 FAs. The conversion of linoleic acid to linolenic acid in the body is likely to be inhibited by diabetes, viral infections, alcohol, cholestrol, saturated fats and highly processed vegetable oil, such as is found in margarine. It is probable that most individuals' production of EPA and DHA is less than adequate. For this reason, ensuring an adequate supply of Omega 6 FAs is not sufficient - there is a definite need to ensure Omega 3 FAs are supplied in the diet.
