　　　 All of us eat every day, but most of us don’t understand nutrition. We often make mistakes in talking about good diet.

　　　 For example, many people think that foods such as rice, bread and potatoes will make one grow fat. In fact, these foods are very good to one’s health. They are good sources of many vitamins. And in comparison with steak and beef, they contain less amount of calories.

　　　 Some people don’t like canned(罐装的) or frozen vegetables, because they think fresh vegetables cooked at home are always better. This is again wrong. In fact, whether the vegetables are good or not depends more on how they are prepared. Overcooking, for example, destroys good qualities of vegetables. Vegetables cooked in too much water can use a large amount of vitamins.

　　　 It is widely believed extra vitamins provide more energy. But taking more than the body needs doesn’t make it function better.

　　　 It is also wrong to say that vegetables grown in poor, worn-out soil are lower in vitamins than vegetables grown in rich soil. The vitamins in our foods are in the plants themselves. They don’t come from the soil. However, the minerals(矿物质) in a plant depend on the minerals in the soil.

　　　 In short, there are many false ideas about nutrition. We need to correct them.
