According to new research published in the Journal of the American Medical Association, exercise and a Mediterranean-style diet full of fruits and vegetables could help to reduce the chance of mental health decline as one ages. To measure these findings, researchers tracked the exercise and eating habits of more than 1,800 adults between 1992 and 2006, noting how strictly each participant stuck to a regular exercise routine and a diet rich in fruits, vegetables, lean fish, and olive oil. People who closely followed the diet reduced their risk of developing Alzheimer’s disease by 40 percent, and those who exercised most reduced their risk by 33 percent, compared to adults who didn’t follow the diet or who did not exercise, the Wall Street Journal writes. As a result of these findings, more and more doctors and nutritionists are recommending that people with higher risks of cognitive degeneration focus on developing a regular exercise plan, as well as encouraging a diet that’s rich with specific foods like fish, olive oil, olives, polenta, whole grain pasta, grapes, spinach, tomatoes, nuts, yogurt, beans, garlic, and broccoli.
