Much of our good health depends on the cooperation（协同作用） between substances（物质）. When they work together ,chemical reactions（反应） take place smoothly. Body systems are kept in balance. Some of the most important helpers in the job of good health are the substances we call vitamins.
Vitamin A is needed to produce a light –sensitive substance in the eyes. People who do not get enough vitamin A can’t see well in the dark. The best source(来源) of vitamin A is fish liver oil. It is also found in the yellow part of eggs. What’s more, squash, sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A.
Vitamin B-1 is also called thiamine. It changes starchy foods into energy. It also helps the heart and nervous system work smoothly. Without it, we would be weak and would not grow. Thiamine is found not just in whole grains like brown rice, but also in other foods. These include beans and peas, nuts and meat and fish.
VitaminB-12 is needed so folic acid can do its work. Together , they help produce red blood cells. Without them, a person suffers from anemia(贫血)。VitaminB-12 is found naturally in foods such as eggs, meat, fish and milk products.
Vitamin C is necessary for strong bones and teeth, and for healthy blood vessels. It also helps wounds heal quickly. The body stores very little Vitamin C. so we must get it very day in foods such as citrus, tomatoes and uncooked cabbage.
