12 Healthy Reasons to Eat an Apple a Day
Alzheimer's Reading Room
A University of Massachusetts-Lowell clinical trial showed that drinking apple juice significantly improved mood and behavior among a group of patients diagnosed with moderate-to-severe Alzheimer's disease. Drinking Apple Juice Improves Mood in Alzheimer's Patients (Video)
Cornell University research also suggests that quercetin may be the compound in apples that protects brain cells against oxidative stress associated with Alzheimer's.

1. Brain Health
Researchers from Cornell University found that apple nutrients protected brain neurons against oxidative damage. Such damage can contribute to neurodegenerative diseases, such as Alzheimer's and Parkinson's. The study highlighted the antioxidant quercetin as a principle compound responsible for the protective effect (Journal of Food Science, 2004, 69: S357-S360).
2. Symptoms of Alzheimer's Disease
A University of Massachusetts-Lowell clinical trial showed that drinking apple juice significantly improved mood and behavior among a group of patients diagnosed with moderate-to-severe Alzheimer's disease. Cornell University research also suggests that quercetin may be the compound in apples that protects brain cells against oxidative stress associated with Alzheimer's.
3. Heart Health
Researchers at the University of California-Davis report that daily consumption of apples and apple juice may help reduce the damage caused by the LDL, the "bad" type of cholesterol, and protect against heart disease (Journal of Medicinal Food, 2000, 3: 159-165).
4. Respiratory System
A National Institutes of Health study reports that foods rich in fiber and flavonoids, found abundantly in apples, may reduce chronic productive cough and other respiratory symptoms (Am. J. Respir. Crit. Care Med, 2004, 170: 279-287).
Research from the United Kingdom reports children of mothers who eat apples during pregnancy are much less likely to exhibit symptoms of asthma at age five. Apples were the only food found to have a positive association with a reduced risk of asthma among a variety of foods consumed and recorded (Thorax, 2007, 62:745-746).
6. Digestive Health
University of Denmark researchers discovered apples and apple products could boost intestinal health by increasing the numbers of good gut bacteria. The friendly bacteria in the intestines feed on apple pectin, a fiber found abundantly in apples (BMC Microbiology 2010, 10:13).
7. Bone Health
A study published in the November 2010 online edition of the American Journal of Clinical Nutrition suggests that older women who eat plenty of fruits, including apples and apple products, along with vegetables and whole grains, may have a lower chance of bone fractures than those not getting their fill.
8. Muscle Strength
A natural compound found in the apple's skin, called ursolic acid, may help prevent muscle wasting that can result from aging and illness (Cell Metabolism, 2011, 13 (6): 627-638).
9. Weight Management or Weight Loss
State University of Rio de Janeiro researchers studying the impact of fruit intake on weight loss found that overweight women who ate the equivalent of three apples a day lost more weight on a low-calorie diet than women who didn't eat the fiber-rich fruit (Nutrition, 2003, 19: 253-256).
10. Metabolic Syndrome
Adults who consume apples, apple juice and apple sauce are likely to have lower blood pressure and trimmer waistlines, resulting in a reduced risk of metabolic syndrome, a cluster of health problems related to diabetes and heart disease (Experimental Biology 2008 Poster (unpublished)).
11. Immune System
Soluble fiber, like apple pectin, may reduce the inflammation associated with obesity-related diseases and strengthen the immune system, according to a University of Illinois study (Brain, Behavior, and Immunity, 2010, in press/available online).
12. Certain types of Cancer, like Breast, Pancreatic, Colon or Liver, Prostate, and Colorectal
Apples are rich in antioxidants, especially quercetin, which have been identified to help inhibit cancer onset and cell proliferation. In one study, the more apples per day individuals ate, the less likely they were to develop colorectal cancer. The anti-cancer effect was seen even when an individual had a low total consumption of fruits and vegetables but consumed at least an apple a day (European Journal of Cancer Prevention, 2010, 19(1):42-47).
"Apples are a delicious way to add a dose of disease prevention to your daily diet," says Allison Parker MS, RD, director of consumer health and education at the U.S. Apple Association. "It is no wonder numerous health organizations, including the Surgeon General, the American Cancer Society and the American Dietetic Association, encourage greater consumption of fruits and vegetables—like apples and apple products."
