Health benefits
Health benefits of apple consumption.[54][55][56][57]
The proverb "An apple a day keeps the doctor away.", addressing the health effects of the fruit, dates from the 19th century Wales.[58] Research suggests that apples may reduce the risk of colon cancer, prostate cancer and lung cancer.[54] Compared to many other fruits and vegetables, apples contain relatively low amounts of vitamin C, but are a rich source of other antioxidant compounds.[47] The fiber content, while less than in most other fruits, helps regulate bowel movements and may thus reduce the risk of colon cancer. They may also help with heart disease,[59] weight loss,[59] and controlling cholesterol,[59] as they do not have any cholesterol, have fiber, which reduces cholesterol by preventing reabsorption, and (like most fruits and vegetables) are bulky for their caloric content.[56][59]
There is evidence that in vitro apples possess phenolic compounds which may be cancer-protective and demonstrate antioxidant activity.[60] The predominant phenolic phytochemicals in apples are quercetin, epicatechin, and procyanidin B2.[61]
Apple juice concentrate has been found to increase the production of the neurotransmitter acetylcholine in mice, providing a potential mechanism for the "prevention of the decline in cognitive performance that accompanies dietary and genetic deficiencies and aging." Other studies have shown an "alleviat[ion of] oxidative damage and cognitive decline" in mice after the administration of apple juice.[57]
However, apple seeds are mildly poisonous, containing a small amount of amygdalin, a cyanogenic glycoside; it usually is not enough to be dangerous to humans, but can deter birds.[62]
