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 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(紅血球).It is found in food like eggs,meat,fish,milk and green vegetables. |
Vitamin C is needed for strong bone and teeth,and for healthy blood vessels(血管).It also helps wounds(傷口) to cure 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 normally,as well to build strong bones.Fish liver oil has vitamin D.In some countries,milk producers add vitamin to milk so that it will be good for children. |
