Women who prefer to drink water instead of sugary sodas or fruit juice are at lower risk of developing diabetes.
Drinking more water helps prevent metabolic disorders, according to a study by the Harvard School of Public Health.
But there is no point in drinking more water if we also consume sweet drinks, experts explain.
It is well established that sweetened beverages increase the risk of developing diabetes, says lead researcher Dr. Frank Hu.
A study tracks the drinking habits of 83,000 women for more than a decade.
In the study period, about 2700 of the participants developed diabetes.
It has been found that sweetened beverages and fruit juices are associated with a higher risk of diabetes - an increase of about 10% for each exam cup per day.
However, the research team estimates that if women replace a glass of soda or fruit juice with a glass of plain water, the risk of diabetes is reduced by 7 or 8%.
Unsweetened coffee or tea is also a good alternative to carbonated drinks. Researchers have found that replacing a glass of soda or fruit juice with a cup of coffee or tea can reduce the risk of developing diabetes by 12-17%.
The results are published in the American Journal of Clinical Nutrition .
