We've all heard that fish is "brain food," and there's good reason for it. Fatty fish like budget-friendly sardines contain omega-3 fatty acids, which are thought to be instrumental in maintaining brain function from early development throughout life. DHA, an omega-3, is present right in the brain, so having those good-for-you omega-3s in your diet is thought to boost brain function.
In addition, components of fatty acids in fish go straight to the synapses of nerve cells, so they play an important role in how neurons communicate with one another, which may have a positive affect throughout life on learning and memory.
