npr:To age well, we must eat well. There has been a lot of evidence that heart-healthy diets help protect the brain.The latest good news: A study recently published in Neurology finds that healthy seniors who had daily helpings of leafy green vegetables — such as spinach, kale and collard greens — had a slower rate of cognitive decline, compared to those who tended to eat little or no greens.“The association is quite strong,” says study author Martha Clare Morris, a professor of nutrition science at Rush Medical College in Chicago. She also directs the Rush Institute for Healthy Aging.Eating Leafy Greens Each Day Tied to Sharper Memory, Slower DeclineIllustration: Meredith Miotke for NPR“To analyze the relationship between leafy greens and age-related cognitive changes, the researchers assigned each participant to one of five groups, according to the amount of greens eaten. Those who tended to eat the most greens comprised the top quintile, consuming, on average, about 1.3 servings per day. Those in the bottom quintile said they consume little or no greens.After about five years of follow-up/observation, “the rate of decline for [those] in the top quintile was about half the decline rate of those in the lowest quintile,” Morris says.So, what’s the most convenient way to get these greens into your diet?“My goal every day is to have a big salad,” says Candace Bishop, one of the study participants. “I get those bags of dark, leafy salad mixes.”A serving size is defined as a half-cup of cooked greens, or a cup of raw greens.” -- source link
