Last month, a report from the Institute of Medicine correlated exercise with helping an aging brain stay sharp. Now, in recent (though not too surprising) news, a healthy diet is again being linked to keeping your brain in tip-top shape. Specifically, researchers found that fruits and veggies helped preserve the memory and thinking skills of 28,000 adults from 40 countries as they aged compared to those whose diets were high in meat and sugar. The study took into account other factors as well—such as the fact that those with healthier eating habits may be less likely to smoke and more likely to exercise. Even so, the findings still pointed to a healthy diet as the common denominator when it came to maintaining cognitive health. What brain-healthy foods should you be piling on your plate? Experts suggest following the MIND diet, which consists of veggies and fruits (especially leafy greens and berries), whole grains, nuts, olive oil, beans, poultry and fish, while eliminating red meat, cheese, butter, sweets and fried foods. Or, just follow one expert’s rule of thumb that 'what’s good for your heart is good for the brain.' What foods do you plan to eat more of to protect your brain?
