Superfoods That Fight Disease

Superfoods That Fight Disease

Spinach


Why it's super: Powerful antioxidants in spinach have been found to combat a variety of cancers, including ovarian, breast, and colon cancers. And it's good for the noggin: Research indicates that spinach reduces the decline in brain function associated with aging and protects the heart from cardiovascular disease. Although it contains relatively high amounts of iron and calcium, oxalate compounds bind to these minerals and diminish their absorption.
How to enjoy it: Spinach has a mild flavor, so spice it up with garlic, olive oil, and onions.

Sweet potatoes


Why they're super: Need a beta-carotene fix? Just one medium sweet potato packs over four times the recommended daily amount. These tasty tubers are also rich in potassium, inflammation-fighting vitamin C, and vitamin B6, which may prevent clogged arteries.
How to enjoy them: Boiling sweet potatoes may cause some of the water-soluble vitamins to leach out, so try them baked, roasted, or cubed, and added to soups or stews. If you need a boost of fiber, make sure to leave the skins on.

Turkey




hy it's super: A 4-ounce portion of turkey breast meat contains almost 50% of your daily selenium, a trace mineral that plays essential roles in immune function and antioxidant defense. Despite the claim that turkey meat causes drowsiness during the holidays, it actually contains high amounts of niacin and vitamin B6, which are important for efficient energy production and blood-sugar regulation.
How to enjoy it: If you roast a whole bird, make sure to remove any skin, which is full of saturated fat; try substituting ground all-white-meat turkey breast for ground beef in your favorite hamburger recipe.

Walnuts

Why they're super: One-quarter cup of walnuts supplies 90% of the daily recommended amount of omega-3 fatty acids, which aid in everything from maintaining cognitive function, to improving cholesterol and blood pressure.
How to enjoy them: Toss a few toasted walnut halves on your oatmeal (another heart-healthy superfood) or try them on your favorite salad for a tasty crunch.

Watercress



Why it's super: Just 1 cup of watercress supplies nearly 100% of a woman's recommended daily amount of vitamin K, which has been shown to prevent hardening of the arteries and is essential for strong bones. It is also a good source of vitamin A, a potent antioxidant.
How to enjoy it: Try these peppery leaves in place of lettuce in salads or sandwiches, or toss them in a quick stir-fry or soup.

Yogurt


Why it's super: Yogurt contains probiotics, which are bacteria that live in the intestine, aid in digestion, boost the immune system, diminish bad breath, and are even associated with longer life spans. A 1-cup serving also supplies one-third of your daily calcium requirement, as well as 14 grams of satisfying protein.
How to enjoy it: Opt for low-fat or nonfat versions to minimize saturated fat, and try substituting plain yogurt for a healthier alternative to sour cream. Lactose intolerant? Look for soy or rice milk varieties.
