It has been claimed that among hunter-gatherer populations, omega-6 fats and omega-3 fats are typically consumed in roughly a 1:1 ratio. [3] [4] [better source needed] At one extreme of the spectrum of hunter-gatherer diets, the Greenland Inuit, prior to the late Twentieth Century, consumed a diet in which omega-6s and omega-3s were consumed in a 1:2 ratio, thanks to a diet rich in cold-water ...
Why you need both omega-3 and omega-6 fats. ... a higher omega-6 to omega-3 ratio was tied to ... Omega-6 fats are also found in nuts (like walnuts, almonds and cashews), peanut butter, eggs, tofu ...
The omega−6:omega−3 ratio of grass-fed beef is about 2:1, making it a more useful source of omega−3 than grain-fed beef, which usually has a ratio of 4:1. [ 103 ] In a 2009 joint study by the USDA and researchers at Clemson University in South Carolina, grass-fed beef was compared with grain-finished beef.

Omega-3 fatty acids have a double bond three carbons away from the methyl carbon, whereas omega-6 fatty acids have a double bond six carbons away from the methyl carbon. The illustration below shows the omega-6 fatty acid, linoleic acid. Polyunsaturated fatty acids can be classified in various groups by their chemical structure:
The evening primrose flower (O. biennis) produces an oil containing a high content of γ-linolenic acid, a type of omega−6 fatty acid.Omega−6 fatty acids (also referred to as ω−6 fatty acids or n−6 fatty acids) are a family of polyunsaturated fatty acids (PUFA) that share a final carbon-carbon double bond in the n−6 position, that is, the sixth bond, counting from the methyl end.
Mammals are unable to synthesize omega−3 fatty acids, but can obtain the shorter-chain omega−3 fatty acid ALA (18 carbons and 3 double bonds) through diet and use it to form the more important long-chain omega−3 fatty acids, EPA (20 carbons and 5 double bonds) and then from EPA, the most crucial, DHA (22 carbons and 6 double bonds).
