              Food which contains vitamins and
              minerals are called  protective

              food because they protect us from
              diseases.Vitamins and minerals keep

              needs vitamins and minerals in a very
              small quantity.


              Roughage And Water                                             Fruits and Vegetables

              Roughage means fibre. Raw fruits and vegetables; cereals have fibre in them.
              Roughage does not provide any nutrient but it helps in the proper functioning of

              the digestive system. It enhances the movement of food through the intestine and
              easy removal of waste. Water is a very important part of life. It maintains our body
              temperature  and helps in digestion. We lose water by means of urine, sweat and

              breath, so, we should drink plenty of water every day.
