学文网Every one of us eats every day， but most don’t know everything about nutrition. And so we often make mistakes in talking about a good eating habit.
For example， many people think that foods， such as rice， bread and potatoes， will make one fat. In fact， those foods are very good to one’s health. They are good sources（来源） of many vitamins（维生素）.
Some people don’t like canned（罐装的） or frozen（冷冻的） vegetables， because they think fresh vegetables cooked at home are always better. This is wrong again. In fact， whether the vegetables are good or not depends more on how they are prepared. Over-cooking， for example， destroys（破坏） many good qualities（质量） of vegetables. Vegetables cooked in too much water will lose a large number of vitamins.
It is widely believed that more vitamins offer（提供） 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 soil（土壤） 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.
In short， there are many wrong ideas about nutrition. We need to correct them.
