The 25 Healthiest Foods

The following is a "healthy food hot list" consisting of the 29 food that will give you the biggest nutritional bang for you caloric buck, as well as decrease your risk for deadly illnesses like cancer, diabetes and heart disease. Along with each description is a suggestion as to how to incorporate these power-foods into your diet.

Fruits

01. Apricots

The Power: Beta-carotene, which helps prevent free-radical damage and protect the eyes. The body also turns beta-carotene into vitamin A, which may help ward off some cancers, especially of the skin. One apricot has 17 calories, 0 fat, 1 gram of fiber. Snacks on them dried, or if you prefer fresh, buy when still firm; once they soften, they lose nutrients.

02. Avocados

The Power: Oleic acid, an unsaturated fat that helps lower overall cholesterol and raise levels of HDL, plus a good dose of fiber. One slice has 81 calories, 8 grams of fat and 3 grams of fiber. Try a few slices instead of mayonnaise to dress up your next burger.

03. Raspberries

The Power: Ellagic acid, which helps stall cancer-cell growth. These berries are also packed with vitamin C and are high in fiber, which helps prevent high cholesterol and heart disease. A cup has only 60 calories, 1 gram of fat and 8 grams of fiber. Top plain low-fat yogurt or oatmeal (another high fiber food) with fresh berries.

05. Cantaloupe

The Power: Vitamin C (117mg in half a melon, almost twice the recommended daily dose) and beta-carotene - both powerful antioxidants that help protect cells from free-radical damage. Plus, half a melon has 853mg of potassium - almost twice as much as a banana, which helps lower blood pressure. Half a melon has 97 calories, 1 gram of fat and 2 grams of fiber. Cut into cubes and freeze, then blend into an icy smoothie.

06. Cranberry Juice

The Power: Helps fight bladder infections by preventing harmful bacteria from growing. A cup has 144 calories, 0 grams of fat and 0 fiber. Buy 100 percent juice concentrate and use it to spice up your daily H20 without adding sugar.

07. Tomato

The Power: Lycopene, one of the strongest carotenoids, acts as an antioxidant. Research shows that tomatoes may cut the risk of bladder, stomach and colon cancers in half if eaten daily. A tomato has 26 calories, 0 fat and 1 gram of fiber. Drizzle fresh slices with olive oil, because lycopene is best absorbed when eaten with a little fat.

08. Raisins

The Power: These little gems are a great source of iron, which helps the blood transport oxygen and which many women are short on. A half-cup has 218 calories, 0 fat and 3 grams of fiber. Sprinkle raisins on your morning oatmeal or bran cereal - women, consider this especially during your period.

09. Figs

The Power: A good source of potassium and fiber, figs also contain vitamin B6, which is responsible for producing mood-boosting serotonin, lowering cholesterol and preventing water retention. The Pill depletes B6, so if you use this method of birth control, make sure to get extra B6 in your diet. One fig has 37 to 48 calories, 0 fat and 2 grams of fiber. (Cookie lovers - fig bars have around 56 calories, 1 gram of fat and 1 gram of fiber per cookie). Fresh figs are delicious simmered alongside a pork tenderloin and the dried variety make a great portable gym snack.

10. Lemons/Limes

The Power: Limonene, furocoumarins and vitamin C, all of which help prevent cancer. A wedge has 2 calories, 0 fat and 0 fiber. Buy a few of each and squeeze over salads, fish, beans and vegetables for fat free flavor. See also: Beneficial Bytes: Lemons and Limes.

Vegetables

11. Onions

The Power: Quercetin is one of the most powerful flavonoids (natural plant antioxidants). Studies show it helps protect against cancer. A cup (chopped) has 61 calories, 0 fat and 3 grams of fiber. Chop onions for the maximum phytonutrient boost, or if you hate to cry, roast them with a little olive oil and serve with rice or other vegetables.

12. Artichokes

The Power: These odd-looking vegetables contain silymarin, an antioxidant that helps prevent skin cancer, plus fiber to help control cholesterol. One medium artichoke has 60 calories, 0 fat and 7 grams of fiber. Steam over boiling water for 30 to 40 minutes. Squeeze lemon juice on top, then pluck the leaves off with your fingers and use your teeth to scrape off the rich-tasting skin. When you get to the heart, you have found the best part!

13. Ginger

The Power: Gingerols may help reduce queasiness; other compounds may help ward off migraines and arthritis pain by blocking inflammation-causing prostaglandins. A teaspoon of fresh gingerroot has only 1 calorie, 0 fat and 0 fiber. Peel the tough brown skin and slice or grate into a stir-fry.

14. Broccoli

The Power: Indole-3-carbinol and sulforaphane, which help protect against breast cancer. Broccoli also has lots of vitamin C and beta-carotene. One cup (chopped) has 25 calories, 0 fat and 3 grams of fiber. Don't overcook broccoli - instead, microwave or steam lightly to preserve phytonutrients. Squeeze fresh lemon on top for a zesty and taste, added nutrients and some vitamin C.

15. Spinach

The Power: Lutein and zeaxanthin, carotenoids that help fend off macular degeneration, a major cause of blindness in older people. Plus, studies show this green fountain of youth may help reverse some signs of aging. One cup has 7 calories, 0 fat and 1 gram of fiber. Add raw leaves to a salad or sauté with a little olive oil and garlic.

16. Bok Choy (Chinese cabbage)

The Power: Brassinin, which some research suggests may help prevent breast tumors, plus indoles and isothiocyanates, which lower levels of estrogen, make this vegetable a double-barreled weapon against breast cancer. A cup will also give you 158mg of calcium (16 percent of your daily recommended requirement) to help beat osteoporosis. A cup (cooked) has 20 calories, 0 fat and 3 grams of fiber. Find it in your grocer's produce section or an Asian market. Slice the greens and juicy white stalks, then saute like spinach or toss into a stir-fry just before serving.

17. Squash (Butternut, Pumpkin, Acorn)

The Power: Winter squash has huge amounts of vitamin C and beta-carotene, which may help protect against endometrial cancer. One cup (cooked) has 80 calories, 1 gram of fat and 6 grams of fiber. Cut on in half, scoop out the seeds and bake or microwave until soft, then dust with cinnamon.

18. Watercress and Arugula

The Power: Phenethyl isothiocyanate, which, along with beta-carotene and vitamins C and E, may help keep cancer cells at bay. One cup has around 4 calories, 0 fat and 1 gram of fiber. Do not cook these leafy greens; instead, use them to garnish a sandwich or add a pungent, peppery taste to salad.

19. Garlic

The Power: The sulfur compounds that give garlic its pungent flavor can also lower LDL ("bad") cholesterol, lower blood pressure and even reduce your risk of stomach and colon cancer. A clove has 4 calories, 0 fat and 0 fiber. Bake a whole head for 15 to 20 minutes, until soft and sweet and spread on bread instead of butter.

Grains, Beans and Nuts

20. Quinoa

The Power: A half cup of cooked quinoa has 5 grams of protein, more than any other grain, plus iron, riboflavin and magnesium. A half-cup has 318 calories, 5 grams of fat and 5 grams of fiber. Add to soup for a protein boost. Rinse first, or it will taste bitter.

21. Wheat Germ

The Power: A tablespoon gives you about 7 percent of your daily magnesium, which helps prevent muscle cramps; it is also a good source of vitamin E. One tablespoon has 27 calories, 1 gram of fat and 1 gram of fiber. Sprinkle some over yogurt, fruit or cereal.

22. Lentils

The Power: Isoflavones, which may inhibit estrogen-promoted breast cancers, plus fiber for heart health and an impressive 9 grams of protein per half cup. A half-cup (cooked) has 115 calories, 0 fat and 8 grams of fiber. Isoflavones hold up through processing, so buy lentils canned, dried or already in soup. Take them to work, and you will have a protein packed lunch.

23. Peanuts

The Power: Studies show that peanuts or other nuts (which contain mostly unsaturated "good" fat) can lower your heart-disease risk by over 20 percent. One ounce has 166 calories, 14 grams of fat and 2 grams of fiber. Keep a packet in your briefcase, gym bag or purse for a protein-packed post-workout nosh or an afternoon pick me up that will satisfy you until supper, or chop a few into a stir-fry for a Thai accent.

24. Pinto Beans

The Power: A half cup has more than 25 percent of your daily requirement of folate, which helps protect against heart disease and reduces the risk of birth defects. A half-cup (canned) has 103 calories, 1 gram of fat and 6 grams of fiber. Drain a can, rinse and toss into a pot of vegetarian chili.

25. The Power: Bacteria in active-culture yogurt helps prevent yeast infections; calcium strengthens bones. A cup has 155 calories, 4 grams of fat, 0 grams of fiber. Get the plain kind and mix in your own fruit to keep calories and sugar down. If you are lactose intolerant, never fear -- yogurt should not bother your tummy.

Health Benefits an Apples

According to the latest research, the old saying, "An apple a day keeps the doctor away," is fact, not just folklore. The nutritional stars in apples-fiber, flavonoids, and fructose-translate into apples' ability to keep us healthy.

Cardio-Protective Fiber

Apples contain both insoluble and soluble fiber. One medium (5 ounces) unpeeled apple provides over 3 grams of fiber, more than 10% of the daily fiber intake recommended by experts. Even without its peel, a medium apple provides 2.7 grams of fiber.

Apple's two types of fiber pack a double punch that can knock down cholesterol levels, reducing your risk of hardening of the arteries, heart attack, and stroke.

Apple's insoluble fiber works like bran, latching on to LDL cholesterol in the digestive tract and removing it from the body, while apple's soluble fiber pectin reduces the amount of LDL cholesterol produced in the liver. Adding just one large apple (about 2/3 of a pound) to the daily diet has been shown to decrease serum cholesterol 8-11%. Eating 2 large apples a day has lowered cholesterol levels by up to 16%!

A study published in the Archives of Internal Medicine confirms that eating high fiber foods, such as apples, helps prevent heart disease. Almost 10,000 American adults participated in this study and were followed for 19 years. People eating the most fiber, 21 grams per day, had 12% less CHD and 11% less CVD compared to those eating the least, 5 grams daily. Those eating the most water-soluble dietary fiber fared even better with a 15% reduction in risk of CHD and a 10% risk reduction in CVD.

LDL cholesterol isn't the only harmful compound on apple's removal list. Pectin grabs toxins like the heavy metals lead and mercury, and ushers them out of the body. Both the soluble and insoluble fibers in apples have cancer-protective activity since they relieve constipation and send potentially toxic substances out with the stools.

When it comes to bowel regularity, apple's two types of fiber tackle the job-no matter what it is. Both the insoluble fiber in apples and their soluble fiber pectin help relieve constipation (thus helping to prevent diverticulosis and colon cancer). The insoluble fiber works like roughage, while the pectin, which is found primarily in the skin, acts as a stool softener by drawing water into the stool and increasing stool bulk. On the other hand, because pectin firms up an excessively loose stool, it's also used to treat diarrhea.

Cardio-Protective Flavonoids

A type of pigment in apples that helps provide their color, flavonoids have been extensively researched and found to help prevent heart disease. Researchers in Finland followed over 5,000 Finish men and women for over 20 years. Those who ate the most apples and other flavonoid-rich foods (such as onions and tea), were found to have a 20% lower risk of heart disease than those who ate the least of these foods.

Apples have been singled out as one of the small number of fruits and vegetables that contributed to the significant reduction in heart disease risk seen in a recent meta-analysis of seven prospective studies. Of the more than 100,000 individuals who participated in these studies, those who diets most frequently included apples, tea, onions, and broccoli-the richest sources of flavonoids-gained a 20% reduction in their risk of heart disease.

Apple skin and onions are the two major food sources of a potent flavonoid called quercitin. If, in addition to eating an apple a day, you add 2 tablespoons of onion and 4 cups of green tea (also rich in flavonoids) to your menu, you, like the men who consumed these foods in another study, may have a 32% lower risk of heart attack than people who consume less of these foods.

Quercitin's benefits derive from its antioxidant activity, especially when it teams up with another antioxidant, vitamin C, also found in apples, to bolster the body's immune defenses. This dynamic antioxidant duo provides another way (in addition to fiber) through which apples protect against cancer and also helps prevent the free radical damage to LDL cholesterol that promotes heart disease.
