"As a culture, we tend to ignore the advice to eat more fish. On average, Americans eat about 3.5 ounces of seafood per week. (Think a can of tuna or sardines)."

"But evidence shows that consumption of 8 or more ounces of seafood per week can reduce the risk of death from cardiovascular disease, and some studies have linked a regular fish habit over a lifetime to a lower risk of cognitive decline as well."

"What's more, some research suggests that regular fish consumption among mothers can boost cognitive development in their children."

"'Omega-3s [found in fish] are important, we think, because they reduce inflammation and help neurons function well,' says researcher Jospeph Hibbeln of the National Institutes of Health."
