Apples are one of the most widely cultivated tree fruits. They grow on small, deciduous trees. The proverb "An apple a day keeps the doctor away", addressing the health effects of the fruit, dates from 19th century Wales. According to researchers, apples may reduce the risk of colon cancer, prostate cancer and lung cancer.
Apples should be crisp and firm. Refrigerate or store in a cool, dark place. You can keep for several weeks. Apples release a gas that makes other fruits ripen more quickly, so if you don’t want your fruit to ripen too fast, keep it away from the apples.
