There seem to be an awful lot of articles suggesting that people have a handful of walnuts or seeds to get their omega-3 fatty acids. While this isn’t wholly bad advice, it’s not exactly the most accurate. The problem is it assumes all omega-3s are interchangeable, when in fact they’re not. There are actually several different iterations of the fats, and unfortunately the ones that come from plants are not as healthy as the ones that come from fatty fish (and happily for vegetarians, algae).

The variety of omega-3s in plants is α‐linolenic acid (ALA). The omega-3s in fish are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Humans aren’t able to make EPA or DHA from scratch; we need either to eat them or to form them from shorter fatty acids (like ALA). The body is able to convert ALA into EPA and DHA through a chain of chemical reactions that generally take place in the liver. In this sequence of events, DHA is the final product, arriving a couple of steps after EPA. (For a detailed breakdown of all the reactions needed to take ALA to DHA, see this.)
