Salmon earns rockstar status in matters of the mind. That’s because fatty fish are rich in omega-3 fatty acids, a structural component of the human brain that enables neurons to conduct signals and communicate with other cells. In fact, studies confirm that frequent fish eaters experience slower rates of cognitive decline as they age. Lesson learned: Keep your brain razor-sharp by eating fatty fish like salmon at least twice each week. It’s delicious simply broiled with lemon, but for a more elaborate entrée, try my pesto salmon with artichokes.
