We hear a lot about omega-3 fatty acids and most of what we hear is that we don’t get enough of them in our diets. In the audio clip above, Dr. Daniel Robinson, an associate professor of pediatrics at Northwestern University’s Feinberg School of Medicine, and an attending physician in the Division of Neonatology at Lurie Children’s Hospital, tells WGN’s Steve Alexander about a city-wide study of Chicago adults.

Not surprisingly, the study found that parental intake of omega-3 fatty acids falls below recommended levels, with women consuming even lower amounts of omega-3 fatty acids than men. He says this deficiency, especially of two particular types of omega-3s — EPA, and DHA — may have direct negative effects on children’s health, with those impacts beginning during pregnancy.

The fix is relatively easy: eat more seafood. Dr. Robinson says oily fish such as salmon, tuna, sardines, mackerel and trout, provides the “biggest bang for your buck.” There are omega-3 supplements in capsule form, and while they can help increase someone’s levels of DHA, Dr. Robinson said the best way to consume it is in the whole food, where you’ll also get other nutrients, such as protein, vitamins and micronutrients.
