Some people do feel that having a body that is generally high in acid is a bad thing. This is why alkaline water is thought to be so beneficial. People feel that having an acidic body can lead to a number of problems, although it is believed that the body is capable of maintaining a good PH balance as long as it is getting the right foods and is kept clear of toxins.

Bone Loss : The Problems With Having An Acidic Body
There has been research to show that too much acid in the body can lead to bone loss. This is because bones store calcium which regulates the PH of the body. If blood gets acidic then calcium is drawn from the bones to neutralise the blood and this can lead to problems with the bones. The causes of acid in the blood are thought to be a diet too high in refined sugar, flour, dairy and meat, although this opinion does seem to differ. By avoiding these items or having more alkaline products in the diet such as vegetables and fruit and the alkaline water, it is felt the bones will be healthier. However, there has been very little research done in order to find out whether the water alone can have a big effect or whether dietary changes will be better.
Cancer
There are some people that feel that it is a combination of sugars and acid that cause cancer and therefore feel that the drinking of alkaline water will prevent this. They feel the alkaline properties of the water will neutralise the acid in the body and stop the cancer from spreading. No research has been carried out on people just drinking this water with no other cancer medication to see whether it works alone as a cure as so this is not recommended. Also, no longitudinal studies have been carried out to test the long term effects of the water.
Tooth Decay
It is plaque acid that causes bad breath and rots teeth. This means that anything that can reduce the acid in the mouth will help to prevent both of these. The alkaline water is therefore a way that this can be done. However, avoiding sweet drinks and ones with acid will also help to protect the teeth and tap water has a neutral PH and so although it will not neutralise the acid, it will not cause as much damage as fruit juice or soda.
Diabetes
There have been some experiments carried out on rats to see whether alkaline water can help to reduced the incidence of diabetes. The results looked quite promising but the rats were given an alkaline water supplemented with magnesium, which has been found to help diabetes as well. This means that it is difficult to know whether it was the magnesium or the water that helped. In humans replacing sugary sodas and fruit juices with any sort of water will help to reduce the chance of contracting diabetes as the amount of sugar taken in will be very much reduced.
