               Vitamins:

                   •  Vitamins are needed by the body in very small amounts to keep us fit, healthy
                       and protect us from various diseases.
                   •  Green leafy vegetables and fruits are the major sources of vitamins and minerals.
                       They are also found in milk, meat, fish and eggs.
                   •  If our body doesn’t get sufficient amount of certain vitamins and minerals for a
                       prolonged duration of time, we might suffer from certain diseases called
                       deficiency diseases.
                   •  Since the vitamins and minerals protect the body from such diseases, they are
                       called protective food.
                   •  Vitamins B and C are water soluble vitamins.
                   •  Vitamins A, D, E and K are fat soluble.


               Minerals:
               Minerals too are required in very small amounts to keep our bodies fit and healthy.
