Foods With More Omega-3s Than Fish

English walnuts are highlighted as a standout omega-3 source for non–fish eaters, delivering 2.57 grams of ALA per one ounce—more than what many people assume from seafood. The article argues that plant foods can outperform fish on ALA per serving, pointing to flaxseeds (2.35 grams ALA in one tablespoon; 7.26 grams in one tablespoon of flaxseed oil) and chia seeds (5.06 grams ALA in one ounce). It also notes walnuts’ omega-3 difference: English walnuts provide about three times the ALA of black walnuts. It suggests plant-based options for people avoiding fish or mercury exposure, and mentions fortified foods and leafy greens as additional routes.
