In English it is said that an apple a day keeps the doctor away, a saying that could be translated into Spanish, keeping the rhyme, as “an apple a day from the doctor would free you.” It is not an exaggeration and the key is in each apple is a complex health formula. What makes the apple a true medicine food are the phytochemicals it contains, such as pectin, organic acids, tannins, flavonoids or boron, a mineral in which it is a champion.
