Goal: 2 to 3 servings every week
What it does: The healthy factor in fish is omega-3 fatty acids, and specifically two types known as DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid).
“Fatty fish not only plays a vital role in the health of the membrane of every cell in our body, it also helps protect us from a number of key health threats,” says Laurie Tansman, MS, RD, CDN, a nutritionist at Mount Sinai Medical Center in New York.

While many foods -- such as walnuts, flaxseed oil, and some mayonnaise brands -- claim the benefits of omega-3 fatty acids, Somer cautions that only the DHA or EPA forms of omega-3 can be directly used by the body.
“What you get in foods like walnuts and flaxseed oil is an omega-3 acid known as ALA -- alpha-linoleic acid,” says Somer. “And while it’s certainly good for you, it requires a process in the body to convert it to DHA. And that conversion process can be influenced by a variety of individual factors.”
