Diet: The World Health Organization recommends at least 400 g (3-4 servings) of fruits and vegetables per day to prevent chronic diseases. Other diet strategies include:

• Calorie-reduced diets have shown to control weight, heart disease, stroke from obesity and also helps the brain.

• Omega-3 fatty acid has been shown to reduce the risk of dementia by 33%. The correlation between omega-3 fatty acids and reduction of Alzheimer's risk is still being studied. Omega-3 fatty acids can be found primarily in cold-water fish such as salmon, mackerel, herring and sardines. 650mg is the recommended daily intake of omega-3, an amount that is often difficult to get on a daily basis, therefore supplements are recommended. Additionally, when purchasing fish, those raised in the wild are recommended over farm-raised fish since the latter do not contain significant amounts of the acid.

• Dietary antioxidants from fruits and vegetables reduce the risk of developing Alzheimer's by approximately 20%. Good sources of antioxidants include prunes, raisins, broccoli, berries, spinach, beets and red grapes.

Mental exercise can reduce a person's risk of developing Alzheimer's Disease by approximately 33%. Activities that involve learning something new and then recalling it later are recommended since they activate the parts of the brain that are first affected by Alzheimer's Disease. Conversely, individuals who watch television two or more hours per day are twice as likely to develop Alzheimer's Disease.
