This wintertime super food does double duty as a health booster: Its flesh is loaded with immune-boosting beta carotene, while its seeds are packed with zinc, which helps the body resist infection. To really bolster your immune system, cut a small pumpkin in half, remove and roast seeds to have as a snack later. Bake pumpkin halves in the oven and stuff with wild rice, dried cherries and walnuts.
