Basic Nutrition
Packing in quite a bit of soluble fiber (4 grams per medium apple) for a modest amount of calories (95) makes apples a filling, sweet snack. Plus, a medium apple counts as 1 cup of fruit, so after eating one you’re well on your way to meeting your daily fruit quota (around 2 cups for adults on a 2,000-calorie diet). They also are a good source of immune-boosting vitamin C (providing 14% of the Daily Value).Weight Loss
Apples satisfy hunger for few calories so it’s not surprising that they can be part of a healthy diet that promotes weight loss. And in a recent study, dried apples also helped participants lose some weight. Women who ate a cup of dried apples daily for a year lost some weight and lowered their cholesterol and heart disease markers. Florida State University researchers think apples’ antioxidants and pectin (a type of fiber) are responsible for the benefits—and think that fresh apples would be even more effective.Heart Health
The Florida State study is not the only one to link apple consumption to heart health. Last year, the Iowa Women’s Health Study reported that, among the 34,000-plus women it’s been tracking for nearly 20 years, apples were associated with a lower risk of death from both coronary heart disease and cardiovascular disease. Some years earlier, 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. Experts attribute the heart-healthy benefits to antioxidant compounds found in apples, which help prevent LDL cholesterol from oxidizing and inhibit inflammation. Plus, the soluble fiber in apples has also been shown to lower cholesterol levels.Metabolic Syndrome Protection
People who eat apples may be less likely to suffer from metabolic syndrome, a cluster of symptoms linked to an increased risk of heart disease and diabetes. A National Health and Nutrition Examination Study (NHANES) found that people who had eaten apples in any form over the past day were 27 percent less likely to have symptoms of metabolic syndrome than those who didn’t. The apple eaters also had lower levels of C-reactive protein, a marker of inflammation whose presence in the blood suggests an increased risk for heart disease and diabetes.Exercise Extender
Eating an apple before you work out may boost your exercise endurance. Apples deliver an antioxidant called ‘quercetin’, which aids endurance by making oxygen more available to the lungs. One study showed that quercetin—when taken in supplement form—helped people bike longer.Bone Protection
French researchers found that a flavanoid called phloridzin that is found only in apples may protect post-menopausal women from osteoporosis and may also increase bone density. Boron, another ingredient in apples, also strengthens bones.
Asthma Inhibitor
One recent study shows that children with asthma who drank apple juice on a daily basis suffered from less wheezing than children who drank apple juice only once per month. Another study showed that children born to women who eat a lot of apples during pregnancy have lower rates of asthma than children whose mothers ate few apples.
Alzheimer's Prevention
A study on mice at Cornell University found that the quercetin in apples may protect brain cells from the kind of free radical damage that may lead to Alzheimer's disease.
Lower Cholesterol
The pectin in apples lowers LDL ("bad") cholesterol. People who eat two apples per day may lower their cholesterol by as much as 16 percent.
Lung Cancer Prevention
According to a study of 10,000 people, those who ate the most apples had a 50 percent lower risk of developing lung cancer. Researchers believe this is due to the high levels of the flavonoids quercetin and naringin in apples.
A Cornell University study found that rats who ate one apple per day reduced their risk of breast cancer by 17 percent. Rats fed three apples per day reduced their risk by 39 percent and those fed six apples per day reduced their risk by 44 percent.
Colon Cancer Prevention
One study found that rats fed an extract from apple skins had a 43 percent lower risk of colon cancer. Other research shows that the pectin in apples reduces the risk of colon cancer and helps maintain a healthy digestive tract.
Liver Cancer Prevention
Research found that rats fed an extract from apple skins had a 57 percent lower risk of liver cancer.
Diabetes Management
The pectin in apples supplies galacturonic acid to the body which lowers the body's need for insulin and may help in the management of diabetes.
So, when you hear that old adage, remember: Adages become adages because they are based in fact! Have you had your apple today?
