Fish for teenage boys

Fish may indeed be brain food.The omega-3 fats found in fish -- particularly oily fish like salmon, mackerel and, to a lesser extent, albacore tuna -- are important to early brain development and to maintaining healthy brain function throughout life.
The late-teens are a critical period for the brain "plasticity" that underlies intelligence and emotional and social behavior. Plasticity refers to the brain's ability to reorganize the connections among cells in response to normal experience, like learning a new skill, or to injury.
