Watercress
You’re more likely to find this member of the cabbage family as a garnish instead of the star it is, at least nutritionally speaking. It’s packed with phytonutrients and antioxidants, both of which help prevent disease and slow aging.
One of these is beta-carotene, a type of carotenoid. These compounds help prevent eye diseases and some cancers. Your body converts beta-carotene into vitamin A.
Watercress also has fiber and vitamin K. Just 2 cups of it give you about a third of the vitamin C adults need each day. And cruciferous vegetables have sulfur-based compounds known as glucosinolates that help your body fight off infection and cancer.
Like all cruciferous veggies, watercress helps detox, Moss says. It’s especially good for cleansing the liver.
