We can find different vitamins in different foods. Then which food should we eat to keep us healthy? Let’s look at some important vitamins for the answer.

Vitamin A helps to protect skin(皮膚) 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(肝臟) and the yellow part of eggs. Sweet potatoes, carrots and other dark-coloured fruit and vegetables have something that body can change into vitamin A.

Vitamin B changes food into energy and helps the heart and nerve system(神經(jīng)系統(tǒng)) to work well. Without it, we will be weak and will not grow. Scientists find it in corns and other foods like beans, nuts, meat and fish. Vitamin B helps to make red blood cells(紅血球). You can find in food like eggs, meat, fish, milk and green vegetables.

Vitamin C is good for strong bone and teeth, and for healthy blood vessels(血管). It also helps wounds(傷口) to get better quickly. The body stores little vitamin C, so we must get it everyday in foods like oranges, tomatoes and cabbage.

Vitamin D increases the level of calcium(鈣) in the blood. Calcium is needed for nerve and muscle cells to work well, as well to build strong bones. Fish liver oil has vitamin D. In some countries, milk producers put vitamin into milk so that it will be good for children.
