The old saying “an apple a day keeps the doctor away.” is not as silly as some people think. The body needs fruit and vegetables because they contain vitamins. Many people take extra vitamins in pill form(丸剂), believing that these will make them healthy. But a good diet is made up of nutritive food and this gives all the vitamins you need. The body doesn't need or use extra vitamins, so why they waste money on them?
