The ideal ratio of omega 3 to omega 6 is considered to be 2:1. This was what our traditional diet would normally deliver in the past. Twice as much omega 3 as the omega 6 essential fatty acids. This proportion changed over the last 40-50 years as a consequence of diet that predominantly includes fats extracted from plants such as corn, cotton, peanut, soy, and safflower, and not enough fish, whole grains, beans, raw nuts and seeds, and oils such as the flax oil. In the USA the proportion is about 1:10-30 now. This means that Americans consume about ten-thirty times as much omega 6 as the omega 3. This distorted proportion is responsible for a drastic rise in cardiovascular disease and obesity, among others.
