26 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.
6 Older people need the same amount of vitamins as younger people.
True. Older people need the same amount of vitamins as younger people although they need fewer calories . Certain illnesses raise the requirements for some vitamins, but that is true for the young as well as the old.
7 Food grow in poor soil is lower in vitamins than food grown in rich soil.
False. The vitamins in our food are made by the plants themselves. They dont come from the soil. However, the minerals in a plant depend on the minerals in the soil.
If you have answered these questions correctly, You can say you know much about food and nutrition by todays standards. But remember that nutrition is growing science and that it may be changed as new information is obtained.
The main purpose of the passage is _____.
A to list todays standards of food and nutrition
B to introduce what should be eaten and what not
C to explain what is helpful to your health and what is not.
D to test our nutrition IQ by judging the problems listed
