精选英语四级考试阅读主旨题解题技巧

All of us eat every day, but most of us dont understand nutrition. How much do you know about good nutrition? Are the following statements true or false?

1. People who dont eat meat can stay healthy.

True. As long as people eat enough milk, eggs and meat alternated, they can get enough protein.

2. Fresh vegetables cooked at home are always more nutritious than canned vegetables.

False. The difference depends on how vegetables are prepared than whether they are fresh or canned. Vegetables cooked in too much water lose a great amount of vitamins.

3 Food eaten between meals can be just as good for health as food eaten at regular meals.

True. Nutritional value depends on what type of food you eat, not when you eat them. Eating an egg or an orange between meals can contribute to a good diet.

4. Taking extra vitamins beyond the recommended daily allowances wont give you more energy.

True. Its widely believed that extra vitamins provide more energy. But taking more than the body needs doesnt make it function better, not more than overfilling your gas tank makes your car run better.

5. Natural vitamins are better supplements for the diet than synthetic vitamins.

False. There is no difference. A vitamin has the same properties and specific chemical structure whether made in a laboratory or taken from plant or animal parts.
