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]
