A healthy diet is made upof water and a great many different kinds of foods. We know that healthy foods like fruit,vegetables and fish,are important as they provide us with energy and fibre, without giving us too much fat and sugar. But why is water important?
The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems start as a result of dehydration--a lack of water in the body.Most people are dehydrated at least some of the time, although they probably don't know it .It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.
These doctors think that health problems such as headaches, high blood pressure and asthma bould be helped if people drank more water .They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight.If we drink water, we will probably drink less sugary soft drinks such as Coca-Cola .Doctors also believe that drinking more water may stop people from overeating.They say that many people think that they are hungry when they are, in fact, thirsty .Doctors suggest ,therefore, that we eat less food and drink more water.
There are still many health problems that cannot be solved by drinking water ,so we should not stop going to see the doctor completely.However ,if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.
