Polyunsaturated fatty acids Omega-6 and Omega-3 primary concerns are with hearth health. It's not that Omega-6 fats are bad, we need them and we need Omega-3's. But the typical American diet provides an Omega-6/Omega-3 ratio of about 15:1, whereas our Paleolithic ancestors are thought have had ratios closer to 2:1 or even 1:1.
Since Omega-6's are mostly pro-inflammatory and Omega-3's are anti-inflammatory, a balance of the two acids is essential.
You can find more information in Loren Cordain's research at:
Oops. I can only post one link, but if you look for his paper 'Fatty acid analysis of wild ruminant tissues ...' and another: 'Realigning Our 21st Century Diet ...'
Instead of trying to calculate the percentages of it in your diet, just eat grass-fed ruminant flesh primarily and it should take care of itself. Additionally, if you're going to eat nuts, make them macadamias. Cooking with ruminant fat, butter or tropical oils would be better than pig's lard, I suspect.
