Which foods should be eaten to keep us healthy?Let us look at some important vitamins for these answers.
Vitamin A helps prevent skin and other tissues from becoming dry.People who do not get enough vitamin A cannot see well in darkness.Vitamin A is found in fish liver oil.It also is in the yellow part of eggs.Sweet potatoes,carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A.
Vitamin B-one changes starchy（含淀粉的）foods into energy. It also helps the heart and nervous system work smoothly.Without it,we would be weak and would not grow.Vitamin B-one 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.
Vitamin B-twelve is needed so folic acid（叶酸）can do its work. Together, they help produce red blood cells.Vitamin B-twelve is found naturally in foods such as eggs,meat,fish and milk products.Folic acid has been shown to prevent physical problems in babies when taken by their mothers during pregnancy.Vitamin B-twelve is found in green leafy vegetables and other foods,like legumes and citrus fruits.In some countries,it is added to products like bread.
Vitamin C is needed for strong bones and teeth,and for healthy blood passages.It also helps wounds heal quickly.The body stores little vitamin C.So we must get it every day in foods such as citrus（柑橘类）fruits,tomatoes and uncooked cabbage.
Vitamin D increases levels of the element calcium in the blood.Calcium is needed for nerve and muscle cells to work normally.It also is needed to build strong bones.Ultraviolet light from the sun changes a substance in the skin into vitamin D.Fish liver oil also contains vitamin D.
