How women can decrease the risk of diabetes

Women who choose plain water over sweet fizzy drinks or fruit juice have a lower risk of developing diabetes, a new study has revealed. According to researchers at the Harvard School of Public Health, replacing sweet drinks with water could help stave off the metabolic disorder, but
adding water to the sugary beverages a person consumes throughout the day won't make a difference.

WomanThe results are based on the drinking habits of 83,000 women followed for more than a decade.

Lead researcher Frank Hu said it is well established that sugary beverages are bad for diabetes risk.

People have recommended drinking plain water instead of sugar-sweetened beverages, he said, "and the question is whether this kind of substitution has any impact on diabetes".

Hu and his team collected data from the massive Nurses Health Study, which tracked the health and lifestyle of tens of thousands of women across the U.S.

The study included 82,902 women who answered questions about their diet and health over a 12-year span.

Over time, about 2,700 of them developed diabetes.

The amount of water women drank did not seem to influence their diabetes risk - those who drank more than six cups a day had the same risk as women who drank less than one cup a day.

However, sugar-sweetened drinks and fruit juice were tied to a higher risk of diabetes - about 10 percent higher for each cup consumed each day.

The research team estimated that if women replaced one cup of fizzy drink or fruit juice with one cup of plain water, their diabetes risk would fall by 7 or 8 percent.

While it is not a huge reduction in the risk, "because diabetes is so prevalent in our society, even 7 or 8 percent reduction in diabetes risk is quite substantial in terms of the population," Hu said.

About 10 per cent of women, or 12.6million, have diabetes in the U.S.

A 7 percent reduction would mean that instead of ten out of every 100 women having diabetes, the number would be closer to nine out of every 100.

The study also found that unsweetened coffee or tea might be a good alternative to sugary beverages.

The researchers estimated that replacing one cup of a carbonated drink or fruit juice with one cup of coffee or tea could reduce the risk of developing diabetes by 12 to 17 percent.

Hu said the study is important in pointing out that fruit juice is not an optimal substitute for soda or other sugar-sweetened drinks.

"The reality is those juices contain the same amount of calories and sugar as soft drinks," the Daily Mail quoted him as saying.

The bottom line, he said, is that plain water is one of the best calorie-free choices for drinks, and "if the water is too plain, you can add a squeeze of lemon or lime".

The study has been published in the American Journal of Clinical Nutrition.
