is necessary for your body to digest and absorb vitamins and nutrients.It also detoxifies(除去的毒素)livers and kidneys，and carries away waste from the body.And when it comes to digestion it will not happen without water.Fiber alone cannot aid proper digestive function by itself.In fact，without water as its partner，good fiber goes bad，causing constipation(便秘)and extreme discomfort.Drinking water is important if youre trying to lose weight and some studies have shown that thirst and hunger sensations take place together.If there is slight dehydration(脱水)，the thirst mechanism may be mistaken for hunger and one may eat some food.As most food contains some water，if one doesnt drink much water they may be driven to eat more food to gain the necessary water supply.However，you also gain the undesirable effects of increased calories.Drinking more water can help to prevent overeating and benefit weight loss.It is better to drink smaller quantities of water more frequently than to drink a lot of water at one time.It is recommended to drink 8 to 12 ounces a day and if you have not been drinking water regularly，you should double the recommended amount because your cells are already dehydrated.Make sure that you dont drink too much water in the morning prior to any physical activity.It is very essential to plan a proper routine for water drinking.Water which is not harmful to health and has all qualities to serve as drinking water is called potable water.The potable water must be free from heavy metals，suspended particles and pathogens like bacteria.The polluted sky，dusty winds，chemicals spewed(涌出)from industries get dissolved with rainwater，causing acid rain.It is not advisable to drink such rainwater.【解题导语】
