A Dutch study found that people who consume diets rich in omega-3 fatty acids, a type of fat found in cold-water fish such as salmon and mackerel, were less likely to suffer from depression than people whose diets were low in this important fat. Another study, this one conducted in England, found that pregnant women who didn’t eat fish had twice the rate of depression as women who ate 10 ounces of fish a day. In fact, one reason researchers think the rate of depression has skyrocketed in this country is that we get so few omega-3 fatty acids in our diets. Another good idea for getting your omega-3s: Keep a container of ground flaxseed in the fridge. Flaxseeds, walnuts, soybeans, kidney beans, and black beans are all excellent sources
