10. Watercress to reduce DNA damage
A recent study published in the British Journal of Nutrition found that watercress, a peppery green from the mustard family, effectively countered the “wear and tear” effects of exercise. Healthy young men were given about 3 ounces of watercress daily for eight weeks, and asked to participate in treadmill workouts that included short bursts of intense exercise. Another exercise group did the workouts without watercress as a control. The men who missed out on watercress experienced more exercise-induced DNA damage, and the benefits were seen after just one dose. In other words, those who ate the green for the first time just two hours before hitting the treadmill experienced the same benefits as those who had munched on it daily for two months. Watercress makes a wonderful salad base and, like spinach and kale, it can be whipped into a smoothie.
