8) Spinach
It may be green and leafy, but spinach is no nutritional wallflower. This noted muscle builder is a rich source of plant-based omega-3s and folate, which help reduce the risk of heart disease, stroke, and osteoporosis. Bonus: Folate also increases blood flow to the nether regions, helping to protect you against age-related sexual issues. And spinach is packed with lutein, a compound that fights macular degeneration. Aim for 1 cup fresh spinach or 1/2 cup cooked per day.
Substitutes: Kale, bok choy, romaine lettuce
FIT IT IN: Make your salads with spinach; add spinach to scrambled eggs; drape it over pizza; mix it with marinara sauce and then microwave for an instant dip.
PINCH HITTER: Sesame Stir-Braised Kale > Heat 4 cloves minced garlic, 1 Tbsp. minced fresh ginger, and 1 tsp. sesame oil in a skillet. Add 2 Tbsp. water and 1 bunch kale (stemmed and chopped). Cover and cook for 3 minutes. Drain. Add 1 tsp. soy sauce and 1 Tbsp. sesame seeds.
7) Yogurt
Various cultures claim yogurt as their own creation, but the 2,000-year-old food's health benefits are not disputed: Fermentation spawns hundreds of millions of probiotic organisms that serve as reinforcements to the battalions of beneficial bacteria in your body. That helps boost your immune system and provides protection against cancer. Not all yogurts are probiotic, though, so make sure the label says "live and active cultures." Aim for 1 cup of the calcium and protein-rich goop a day.
SUBSTITUTES: Kefir, soy yogurt.
FIT IT IN: Yogurt topped with blueberries, walnuts, flaxseed, and honey is the ultimate breakfast--or dessert. Plain low-fat yogurt is also a perfect base for creamy salad dressings and dips.
HOME RUN: Power Smoothie > Blend 1 cup low-fat yogurt, 1 cup fresh or frozen blueberries, 1 cup carrot juice, and 1 cup fresh baby spinach for a nutrient-rich blast.
6) Tomatoes
There are two things you need to know about tomatoes: Red are the best, because they're packed with more of the antioxidant lycopene, and processed tomatoes are just as potent as fresh ones, because it's easier for the body to absorb the lycopene. Studies show that a diet rich in lycopene can decrease your risk of bladder, lung, prostate, skin, and stomach cancers, as well as reduce the risk of coronary artery disease. Aim for 22 mg of lycopene a day, which is about eight red cherry tomatoes or a glass of tomato juice.
SUBSTITUTES: Red watermelon, pink grapefruit, Japanese persimmon, papaya, guava
FIT IT IN: Pile on the ketchup and Ragú; guzzle low-sodium V8 and gazpacho; double the amount of tomato paste called for in a recipe.
PINCH HITTER: Red and Pink Fruit Bowl > Chop 1 small watermelon, 2 grapefruits, and 1 papaya. Garnish with mint.
5) Carrots
Most red, yellow, or orange vege- tables and fruits are spiked with carotenoids--fat-soluble compounds that are associated with a reduction in a wide range of cancers, as well as reduced risk and severity of inflammatory conditions such as asthma and rheumatoid arthritis--but none are as easy to prepare, or have as low a caloric density, as carrots. Aim for 1/2 cup a day.
SUBSTITUTES: Sweet potato, pumpkin, butternut squash, yellow bell pepper, mango.
FIT IT IN: Raw baby carrots, sliced raw yellow pepper, butternut squash soup, baked sweet potato, pumpkin pie, mango sorbet, carrot cake.
PINCH HITTER: Baked Sweet Potato Fries > Scrub and dry 2 sweet potatoes. Cut each into 8 slices, and then toss with olive oil and paprika. Spread on a baking sheet and bake for 15 minutes at 350°F. Turn and bake for 10 minutes more.
