【简答题】
Your body, which has close relations with the food you eat, is the most important thing you own, so it needs proper treatment and proper nourishment. 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 vitamin C. Many people take extra vitamins in pill form, believing that these will make them healthy. But a good diet is made up of nourishing food and this gives all the vitamins you need. The body doesn't need or use extra vitamins, so why waste money on them? In the modern western world, many people are too busy to bother about eating properly. They throw anything into their stomachs, eating hurriedly and carelessly. The list of illnesses caused or made worse by bad eating habits is frightening.
