keeping healthy
1 diet and exersise
1.1 a) A healthy diet contains the right balance of the different foods you need and the right amount of energy. Carbohydrates, fats and proteins are used by the body to release energy and to build cells. Mineral ions and vitamins are needed in small amounts for healthy functioning of the body. A person is malnourished if their diet is not balanced. This may lead to a person being overweight or underweight. An unbalanced diet may also lead to deficiency diseases or conditions such as type 2 diabetes.
1.2 b) A person loses mass when the energy contentof the food taken in is less than the amount of energy expended by the body. Exersise increases the amount of energy expended by the body
