I've stopped supplementing fish oil based on concerns over oxidation and shelf life, since I eat quite a bit of wild-caught fish and shellfish already. While our brains may have evolved on a diet that included fish, there is certainly room for discussion over dietary needs for ω-3 of healthy adults today. Perhaps the issue in "getting more ω-3s into the diet" is less about ω-3s per se and more about ω-6s: the SAD is so reliant on nasty industrial oils that whatever range of healthful ω-6:ω-3 we may have consumed in our recent past is jacked to hell. So the simple presription would be: cut down on industrial oils and processed fats (ω-6), eat wild fish and shellfish when possible (ω-3), make your meat selections grass-fed ruminants when possible (ω-3), and if you feel the need to supplement fish oil be sure it is of the highest quality.
