Omega-3 Fatty Acids
Omega-3 fatty acids are essential for normal brain functioning and development. Research shows a 10 percent reduction in cognitive decline in older adults who eat fish at least once a week, according to the Australian Nursing Journal. Choose cold water fatty fish such as salmon, sardines or mackerel, which are rich in the omega-3 fatty acid docosahexaenoic acid (DHA). If you can't eat that much fish, try flaxseed meal, walnuts or tofu, which are excellent sources of the omega-3 fatty acid alpha-linolenic acid (ALA). Supplements also can help you consume adequate amounts of this brain-boosting fuel.
