Answer 1

• Minerals and vitamins are needed in very small quantities by our body but are an important part of the balanced diet because:

(i) Vitamins help in protecting our body against diseases. These are necessary for good eyesight (Vitamin A ), growth (Vitamin B), keeping teeth, gums and joints healthy (Vitamin C) and for normal growth of bones and teeth (Vitamin D). (1.5 marks)

(ii) Minerals are needed in our body for building bones and teeth (calcium and phosphorus), formation of blood (iron), coagulation of blood and functioning of muscles (calcium) and functioning of the thyroid gland (iodine). Thus, they assist in the proper functioning, normal growth and good health. (1.5 marks)
