tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality. Be sure to allow yourself from seven to nine hours each night.

　Finally, get plenty of exercise. Exercise firms the body, strengthens the muscle and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life span. Any kind of exercise is good.

Test your nutrition IQ

　All of us eat every day, but most of us don't understand nutrition. How much do you know about good nutrition? Are the following statements true or false?

　1. People who don't eat meat can stay healthy.

　True. As long as people eat enough milk, eggs and meat alternatives(取舍), they can get enough protein.

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

　False. The differences depend more on how vegetables are prepared than whether they are fresh or canned. Vegetables cooked in too much water can 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 types of food you eat, not when you eat them. Eating an egg or an orange between meals can contribute to a good diet.

　4. Food grown in poor soil is lower in vitamins that food grown in rich soil.

　False. The vitamins in our food are made by the plants themselves. They don't come from the soil. However, the minerals in a plant depend on the minerals in the soil.

If you have answered the above questions correctly, you can say you know much about food and nutrition by today's standards. But remember that nutrition is a growing science and that it may change as new information is obtained.
