Certain nutrients, chemicals and vitamins, such as omega-3 fatty acid, vitamin E, glucose and caffeine, can be particularly good for brain health. A few healthy foods that fit the bill include blueberries, avocados, dark chocolate, wild salmon, nuts, seeds, beans, tea and whole grains. Healthy foods can be incorporated into the diet at any stage of life for brain health and may be particularly crucial for aging adults who need to preserve brain function as they get older.
Some doctors believe that blueberries are particularly beneficial for brain health. Those who want to incorporate these berries into their diet do not have to do so just at peak season; freeze-dried or frozen blueberries are said to be just as beneficial as fresh berries. The healthy omega-3 fatty acids found in avocados may also be helpful for maintaining brain health and functionality. According to WebMD, modest amounts of caffeine may also be good for helping to stimulate brain function, with doctors recommending 2 or 3 cups of freshly brewed tea per day. Those who prefer to be a bit more indulgent in their caffeine intake can supplement with small amounts of dark chocolate.
