                                 A balanced diet




              The human body needs to be in good health. Good health
              conditions are supported by eating well balanced diets. In this
              chapter, you will learn how to identify groups of food which
              make a balanced diet.  Also, you will plan a balanced diet and

              identify its importance in the human body. A balanced diet is
              a meal that contains all food groups.



              Groups of food

              We eat food based on the nutrients required in the body.
              These nutrients are required in the right proportion depending
              on the needs of the body. The right quantities and proportions
              of nutrients needed make a balanced diet. A balanced diet

              includes carbohydrates, proteins, fats and oils, vitamins,
              minerals and water.
