HEART HEALTHY FOODS 9-15
9. Apples
Apples were associated with a lower risk of death from both coronary heart disease and cardiovascular disease in the Iowa Women’s Health Study, which has been tracking 34,000-plus women for nearly 20 years. Finnish researchers studying dietary data collected over 28 years from 9,208 men and women found that frequent apple eaters had the lowest risk of suffering strokes compared with nonapple eaters. What explains the hearty benefits? Researchers suggest that the strong antioxidant flavonoid compounds found in apples—quercetin, epicatechin, epigallocatechin, kaempferol and other polysyllabic wonders—play a key role by preventing “bad” LDL cholesterol from oxidizing and triggering a series of events that result in the buildup of plaque in arteries, as well as inhibiting inflammation. Apples are also rich in pectin, a form of soluble fiber known to help lower cholesterol, and they provide a decent amount of vitamin C, another antioxidant.
10. Berries
Eating just under a cup of mixed berries daily for eight weeks was associated with increased levels of “good” HDL cholesterol and lowered blood pressure, two positives when it comes to heart health, according to a study of 72 middle-age people published recently in the American Journal of Clinical Nutrition. Included in the mix were strawberries, red raspberries and bilberries—similar to blueberries—as well as other berries more common in Finland (where the research was conducted): black currants, lingonberries and chokeberries. The diverse range of polyphenols—a broad class of health-promoting plant compounds that includes anthocyanins and ellagic acid—provided by the mix of berries is likely responsible for the observed benefits. Polyphenols may increase levels of nitric oxide, a molecule that produces a number of heart-healthy effects. One is helping to relax blood vessels, which subsequently results in lowered blood pressure.
11. Pomegranates
Studies have shown that the fruit may help to reduce the buildup of plaque in arteries and lower blood pressure. Experts believe that pomegranate’s benefits come from its powerful punch of polyphenols—including anthocyanins (found in blue, purple and deep-red foods) and tannins (also found in wine and tea). In a 2008 study, researchers found that compared with other antioxidant-rich beverages including blueberry juice, cranberry juice and red wine, “pomegranate [juice] naturally has the highest antioxidant capacity,” reports David Heber, M.D. Ph.D., study collaborator and director of the UCLA Center for Human Nutrition.
12. Bananas
One banana has 422 mg—about 12 percent of your recommended daily dose—of potassium. The potassium in bananas helps maintain normal heart function and the balance of sodium and water in the body. Potassium helps the kidneys excrete excess sodium, thereby contributing to healthy blood pressure. This mineral is especially important for people taking diuretics for heart disease, which combat sodium and water retention but also strip potassium from the body in the process. Other good sources include sweet potatoes (694 mg for one medium), nonfat yogurt (579 mg for 1 cup) and spinach (419 mg for 1/2 cup, cooked).
13. Popcorn
Popcorn delivers polyphenols—antioxidants linked to improving heart health. Gram for gram, popcorn boasts three times more polyphenols than kidney beans (the highest vegetable polyphenol source) and four times more than cranberries (the best fruit source), according to recent research out of the University of Scranton.
What’s more, popcorn is a whole grain—and people who eat plenty of whole grains tend to be leaner and have a lower risk of heart disease than those who don’t.
14. Green Tea
Some of the strongest evidence of tea’s health benefits comes from studies of heart disease. Scientists have found that those who drink 12 ounces or more of tea a day are about half as likely to have a heart attack as nontea drinkers.
Scientists also reported in 2009 that Japanese men who drank a daily cup of green tea significantly lowered their risk of developing gum disease—the more tea, the lower the risk. The researchers believe antioxidants called catechins in green tea are the key. Catechins hamper the body’s inflammatory response to the bacteria that cause gum disease. People with gum disease are twice as likely to suffer from heart problems.
15. Wine/Alcohol
Scientific literature indicates that people who drink moderately are less likely to have heart disease than those who abstain. Drinking in moderation may protect the heart by raising “good” HDL cholesterol, decreasing inflammation and “thinning the blood” (preventing clots that can cause heart attack and stroke). Moderate drinking also increases estrogen, which protects the heart—a benefit particularly helpful to postmenopausal women whose reduced estrogen levels increase their risk of heart disease. Remember, 1 drink equals 12 ounces of beer, 5 ounces of wine or 1.5 ounces of liquor.
