Nutritional value
Although the nutrient levels are lower than in some other fruits, the range of nutrients in apples is wide, and having 'an apple a day' is still thought to be a good idea. Apples have useful, if not large, amounts of vitamin C, but they are an excellent source of antioxidants and phytochemicals, including flavonoids and phenols. The high content of the phytochemical quercetin is thought to help prevent various illnesses, including diabetes. Along with another flavonoid, catechin, it has been found to lower cholesterol levels and improve lung function. Some research shows that regular consumption of apples (and tomatoes) can improve lung capacity and reduce wheezing in asthmatics.
