Q: In The Origin Diet, you recommend eating fatty fish for the healthy oils. Luckily, I love fish, but could you tell me what other fish besides salmon are in this category? How about catfish, one of my favorites?

A: Excellent sources of omega-3 fats (2 to 4 grams/3.5 ounce serving) include salmon, mackerel, lake trout, herring, bluefin tuna, sturgeon, sardines.
“OK” sources (0.4 to 0.9 grams/3.5 ounce serving) include halibut, striped bass, pollock, catfish, rainbow trout, carp, shrimp, crab, and lobster).
“Fair to Poor” sources (< 0.3 grams/3.5 ounce serving) include sole, flounder, perch, cod, grouper, haddock, red snapper, and clams). – Elizabeth Somer

Q: I have just started The Origin Diet and feel great! You don’t mention sardines, which happen to be my favorite fish. Are they OK?

A: Yes! Sardines, as well as mackerel and salmon, are some of the best dietary sources of the omega-3 fatty acids that I discuss in The Origin Diet help boost mental function, improve mood, and lower risk for numerous diseases from heart disease to possibly arthritis. Enjoy your sardines! – Elizabeth Somer
