Our body needs vitamins in tiny amounts. Some people buy pills or tablets that contain vitamins. But this isnZt really necessary, because most of us eat vitamins and salts in (with) food. Vitamins help all parts of the body to work properly and to stay healthy and some vitamins help keep our eyes ,skin healthy and make our blood vessels strong. In fresh fruit and green vegetables you can find Vitamin C. This vitamin keeps our skin and gums healthy. Fish, milk, butter ,cheese, margarine contain Vitamin D. This is only a vitamin we can make for ourselves when the skin get enough sunshine.
Vitamin D helps your bones to grow stong and hard.Our body need water as well as solid foods. People have survived for a month or more without food. But we cannot stay alive without water. A large part of your body is made up of water. About two-thirds (66 %) as your body is water. We lose water when we go on the toilett, breath or sweat.Then you feel thirsty. If you want to stay healthy, you must drink as much water as your body loses. We find water in food that we eat and in milk that we drink.
All other drinks are mostly water but many drinks that we buy in bottles or cans are just water with a little sugar and flavouring. Most food have some mineral salts in them. Some of these minerals are used, together with proteins, to build our bones and other are used to help build our muscles and nerves or other mineral salts are used for teeth and blood. All parts of our body are in need of mineral salts.Some of the most important mineral salts are calcium salts that we can find in milk, butter, cheese, yoghurt, bread, cabbage and many other foods. Calcium salts are used by your body to make healthy bones and teeth. « mai multe referate din Diverse
