Re: Pupils keep brains oiled. It is true that Omega-3 is an essential fatty acid.

However, fish only accumulate it from eating their vegetables (well, algae). It is also obtainable from leafy green vegetables, walnuts, pumpkin seeds and in flax oil and dietary supplements made from it.

So vegetarians and fish-haters need not despair!
