These data make it very clear that the best way to reduce your intake of excessive omega-6 oils lies in restricting intake of chicken and eliminating most tree nuts and vegetable oils from your diet. If you do this, you can easily attain a healthy total diet ratio of omega-6 to omega-3 even if you eat only grain-finished beef, lamb, pork, and bison, by including some fatty fish like salmon, sardines, or sea bass in your diet.
As we saw above, a pound of pork has 1.7 g omega-6 and a pound of fatty beef has 1.0 g. Assuming that you limit all other significant sources of omega-6 in your diet, if you consume 6 pounds of beef in a week, you will get 6 g of omega-6. To get an ideal 1:1 ratio of omega-6: omega-3 in your overall diet, you will need to eat something that will provide 5 g of omega-3s with almost no omega-6, such as salmon or sardines. Take a look at the amounts of omega-3s in these canned fish:
* Salmon, pink, canned, solids with bone and liquid, 100 g, 1.7 g
* Sardine, Pacific, canned in tomato sauce, drained solids with bone, 100 g, 1.7 g
Thus, 350 g (12 ounces) of either salmon or sardines in the week will give you enough omega-3 to balance out 6 pounds of beef. So I could eat a pound of beef each day 6 days each week, then have three-quarters of a pound of salmon on the 7th day, to get the desired ratio. Alternatively, I could eat my pound of beef daily with a few sardines to achieve the same result.
