Thank you, dark chocolate, for making us feel good—not guilty—about dessert. Dark chocolate is filled with flavonoid antioxidants (more than 3 times the amount in milk chocolate) that keep blood platelets from sticking together and may even unclog your arteries.It may also help with weight loss by keeping you feeling full, according to a study from Denmark. Researchers gave 16 participants 100 g of either dark or milk chocolate and 2 hours later offered them pizza. Those who consumed the dark chocolate ate 15% fewer calories than those who had milk chocolate, and they were less interested in fatty, salty, and sugary foods.
Try a chocolate with 70% or more cocoa. Two tablespoons of dark chocolate chips with fresh berries as a midafternoon snack or after-dinner dessert should give you some of the heart-healthy benefits without busting your calorie budget.
One of the healthiest fruits you should be eating is one you probably already are: the apple. The Iowa Women’s Health Study, which has been investigating the health habits of 34,000 women for nearly 20 years, named apples as one of only three foods (along with pears and red wine) that are most effective at reducing the risk of death from heart disease among postmenopausal women. Other massive studies have found the fruit to lower risk of lung cancer and type 2 diabetes—and even help women lose weight.
In fact, one of the only things that could make an apple unhealthy is mixing it with sugar, flour, and butter and stuffing it into a mile-high pie. Instead, have one as an afternoon snack with a tablespoon of peanut butter, or add slices to sandwiches or salads.
A French study published in the Journal of Nutrition found that lychee has the second-highest level of heart-healthy polyphenols of all fruits tested—nearly 15% more than the amount found in grapes (cited by many as polyphenol powerhouses). The compounds may also play an important role in the prevention of degenerative diseases such as cancer.
Serve by peeling or breaking the outer covering just below the stem; use a knife to remove the black pit. Add to stir-fries or skewer onto chicken kebabs to add a sweet, grapelike flavor.
One large Asian pear has a whopping 10 g of cholesterol-lowering fiber, about 40% of your daily need. People who ate the most fiber had the lowest total and LDL cholesterol levels, according to a recent study of Baltimore adults. The same researchers found that people who ate the most fiber also weighed the least and had the lowest body mass index and waist circumference.
Serve by dicing it into a salad of Boston lettuce, crumbled goat cheese, walnuts, and mandarin oranges. Or make it a dessert: Add peeled and cored pears to a saucepan with 1 cup white wine, 1 teaspoon honey, 1 teaspoon grated fresh ginger, and enough water to cover the pears. Cover and simmer 40 minutes or until pears are soft.
Blueberries may very well be the most potent age-defying food—they’re jam-packed with antioxidants. When researchers at Cornell University tested 25 fruits for these potent compounds, they found that tangy-sweet wild blueberries (which are smaller than their cultivated cousins) packed the most absorbable antioxidants. Research shows a diet rich in blueberries can help with memory loss, prevent urinary tract infections, and relieve eyestrain.
Add up to 1/2 cup of blueberries to your diet a day for maximum health benefits, recommends Ronald Prior, PhD, adjunct professor of food science at the University of Arkansas in Fayetteville. This alone provides just about double the amount of antioxidants most Americans get in 1 day.
One of the best ways to get vitamin A—an essential nutrient that protects and maintains eyes, skin, and the linings of our respiratory, urinary, and intestinal tracts—is from foods containing beta-carotene, which your body converts into the vitamin. Beta carotene–rich foods include carrots, squash, kale, and cantaloupe, but sweet potatoes have among the most. A half-cup serving of these sweet spuds delivers only 130 calories but 80% of the DV of vitamin A. Replace tonight’s fries with one medium baked sweet potato (1,096 mcg) and you’re good to go—and then some.
Tomatoes are our most common source of lycopene, an antioxidant that may protect against heart disease and breast cancer. The only problem with tomatoes is that we generally eat them in the form of sugar-loaded jarred spaghetti sauce or as a thin slice in a sandwich. For a healthier side dish idea, quarter plum tomatoes and coat with olive oil, garlic powder, salt, and pepper. Roast in a 400°F oven for 20 minutes, and serve with chicken.
Spinach has serious health muscles. For one thing, it contains lots of lutein, the sunshine-yellow pigment found in egg yolks. Aside from guarding against age-related macular degeneration, a leading cause of blindness, lutein may prevent heart attacks by keeping artery walls clear of cholesterol.
Spinach is also rich in iron, which helps deliver oxygen to your cells for energy, and folate, a B vitamin that prevents birth defects. Cook frozen spinach leaves (they provide more iron when cooked than raw) and serve as a side dish with dinner a few times a week.
Pick any life-threatening disease—cancer, heart disease, you name it—and eating more broccoli and its cruciferous cousins may help you beat it, Johns Hopkins research suggests. Averaging just four weekly servings of veggies like broccoli, cabbage, and cauliflower slashed the risk of dying from any disease by 26% among 6,100 people studied for 28 years.
For maximum disease-fighting benefits, whip out your old veggie steamer. It turns out that steaming broccoli lightly releases the maximum amount of sulforaphane.
These smooth, buttery fruits are a great source of not only MUFAs but other key nutrients as well. One Ohio State University study found that when avocado was added to salads and salsa, it helped increase the absorption of specific carotenoids, plant compounds linked to lower risk of heart disease and macular degeneration, a leading cause of blindness. “Avocados are packed with heart-protective compounds, such as soluble fiber, vitamin E, folate, and potassium,” says Elizabeth Somer, RD, author of 10 Habits That Mess Up a Woman's Diet.
But they are a bit high in calories. To avoid weight gain, use avocado in place of another high-fat food or condiment, such as cheese or mayo.
Edamame and Tofu
Soy’s days as a cure-all may be over—some claims, such as help for hot flashes, don’t seem to be panning out—but edamame still has an important place on your plate. Foods such as tofu, soy milk, and edamame help fight heart disease when they replace fatty meats and cheeses, slashing saturated fat intake. Soy also contains heart-healthy polyunsaturated fats, a good amount of fiber, and some important vitamins.
Soy’s isoflavones, or plant estrogens, may also help prevent breast cancer. Some researchers believe these bind with estrogen receptors, reducing your exposure to the more powerful effects of your own estrogen, says Prevention advisor Andrew Weil, MD. But stick with whole soy foods rather than processed foods, like patties or chips, made with soy powder. Don’t take soy supplements, which contain high and possibly dangerous amounts of isoflavones.
Lean beef is one of the best-absorbed sources of iron there is. (Too-little iron can cause anemia.) Adding as little as 1 ounce of beef per day can make a big difference in the body’s ability to absorb iron from other sources, says Mary J. Kretsch, PhD, a researcher at the USDA-ARS Western Human Nutrition Research Center in Davis, CA. Beef also packs plenty of zinc (even minor deficiencies may impair memory) and B vitamins, which help your body turn food into energy.
If you can, splurge on grass-fed. Compared with grain-fed beef, it has twice the concentration of vitamin E, a powerful brain-boosting antioxidant. It’s also high in omega-3 fatty acids. Because this type of beef tends to be lower in overall fat, it can be tough—so marinate it, and use a meat thermometer to avoid overcooking.
Yes, it does a body good: Studies show that calcium isn’t just a bone booster but a fat fighter too. Recent research from the University of Tennessee found that obese people who went on a low-calorie, calcium-rich diet lost 70% more weight than those who ate the least. Vitamin D not only allows your body to absorb calcium, it’s also a super nutrient in its own right. Recent research found that adequate D levels can reduce heart disease risk, ward off certain types of cancer, relieve back pain, and even help prevent depression, but most of us don’t get nearly enough of the 1,000+ IU daily that most experts recommend.
A splash of milk in your morning coffee isn’t enough to provide the calcium and vitamin D you need. Use milk instead of water to make your oatmeal, have a glass with breakfast, or stir some chocolate syrup into it for an after-dinner treat.
Egg yolks are home to tons of essential but hard-to-get nutrients, including choline, which is linked to lower rates of breast cancer (one yolk supplies 25% of your daily need) and antioxidants that may help prevent macular degeneration and cataracts. Though many of us have shunned whole eggs because of their link to heart disease risk, there’s actually substantial evidence that for most of us, eggs are not harmful but healthy.
People with heart disease should limit egg yolks to two a week, but the rest of us can have one whole egg daily; research shows it won’t raise your risk of heart attack or stroke. Make omelets with one whole egg and two whites, and watch cholesterol at other meals.
