Women on Vegan Diets Have More Long-Chain Omega-3s, Compared with Fish-Eaters
Women following vegan diets have significantly more omega-3 “good fats” in their blood, compared with fish-eaters, meat-eaters, and ovo-lacto vegetarians, according to a new report from the European Prospective Investigation into Cancer and Nutrition (EPIC) Study. Levels in vegan men were not quite as high as in vegan women. Despite zero intake of long-chain omega-3s eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and substantially lower intake of their plant-derived precursor alpha-linolenic acid (ALA), vegan participants converted robust amounts of shorter-chain fatty acids into these long-chain fatty acids. The study included 14,422 men and women aged 39 to 78.
