Some 'brain foods' can lower your risk of Alzheimer's

Food is good for the body and for the mind.

A new study, published in the journal Alzheimer's and Dementia, suggests that eating certain "brain foods" decreases your chances of getting Alzheimer's disease. The neurological disorder is the sixth-leading cause of death in America, according to the Alzheimer's Association.

A "brain food" is a food that is believed to be beneficial to your brain, namely because it helps increase your intellectual power. A few brain power foods include: leafy greens, blueberries, seeds and nuts, fatty fish, olive oil, lentils, legumes and whole grains. These foods are part of a Mediterranean-style diet, according to the Alzheimer's Association, who also reported that this diet lowers the risk for Alzheimer's disease.

Foods that are good for the brain have other benefits, too. "Fortunately, foods that boost your memory also are foods that help to protect your heart," says Melodi Peters, a registered dietitian at Advocate Good Shepherd Hospital in Barrington, Ill.

"Deep colored fruits and vegetables are the best," Peters says. "The deeper the color, the better the source of memory boosting flavonoids. Broccoli, kale, blackberries, blueberries and dark cherries are literally super foods. You should also include whole grains, black or wild rice and whole oats in your diet."

While diet is important for mental health, other factors also contribute. "Maintaining a healthy weight, quality and duration of sleep and regular exercise also play a major role in brain health," says Peters.
