You'd be much better off getting your Omega 3s from fish or grass-fed beef or lamb. Animals and plants may have Omega 3 or 6 fats in them, but they are not the same fats chemically. The ones in seeds usually are not able to be transformed fully into the constituent parts that your body needs and so even though on paper there may a good ratio of O3:O6, what happens inside your body isn't the same. You're not getting the DHA and ALA that you need, for instance. You're better off getting your fats from animals.
