Different vitamins are found in different foods. Then which foods should be eaten to keep us healthy? Let's look at some important vitamins for the answer.
Vitamin A helps to protect skin from becoming dry. It is also helpful to the eyes. Without vitamin A, you cannot see well in darkness. Vitamin A is found in animal liver and yellow part of eggs. Sweet potatoes, carrots and other dark colored fruit and vegetables have something that the body can change into vitamin A. |
Vitamin B changes foods into energy and helps the heart and nervous system (神经系统) to work smoothly. Without it, we will be weak and will not grow. It is found in grains and other foods like beans, nuts, meat and fish. Vitamin B helps to produce red blood cells. It is found in foods like eggs, meat, fish, milk and green leafy vegetables. |
Vitamin C is needed for strong bones and teeth, and for healthy blood vessels (血管). It also helps wounds to heal (愈合) quickly. The body stores little vitamin C, so we must get it in foods like oranges, and cabbage. |
Vitamin D increases the levels of calcium (钙) in the blood. Calcium is needed for verve and muscle (肌肉) cells to work normally, as well as to build strong bones. Fish liver oil has vitamin D. In some countries, milk producers add vitamin D to milk so that it will be good for children. |
