Onions

You’ll get the most out of this veggie’s cancer-fighting antioxidants by eating it raw; cooking onions at a high heat reduces the benefits of phytochemicals that protect against lung and prostate cancer. Try combining chopped raw onions with tomatoes, avocado and jalapeño peppers for a blood sugar–friendly pico de gallo-like dip. Finish with a splash of lime juice. Before you get chopping, learn the answer to your big question: Why do onions make you cry?

Broccoli

Broccoli is full of cancer-fighting antioxidants.

Spinach

Spinach is packed with carotenoids—antioxidants that promote healthy eyes and help prevent macular degeneration, the leading cause of blindness in older adults. Cooking these green vegetables helps make lutein (a carotenoid) more absorbable by your body. These 21 spinach side dishes are perfect for when you’re not in the mood for a salad.

Alfalfa sprouts

This tiny powerhouse is rich in beta-carotene, an antioxidant that protects against lung cancer and helps maintain healthy skin, hair, nails, gums, glands, bones and teeth. It’s also a good source of vitamin E, which may help prevent heart attacks and strokes, and lower the risk of death from bladder cancer. By the way, these are the fruits and veggies you should, and shouldn’t, peel before eating.

The antioxidants in these green vegetables can help detoxify cancer-causing free radicals, and with 80 percent of your daily vitamin C in just 1/2 cup, also help fight heart disease and ward off cataracts. Try sautéing your brussels sprouts with a little bacon or olive oil and mustard for a smoky kick. It can’t hurt to work some of these most nutritious foods in the world into your diet as well.
