Woman who guzzle sugar-sweetened fruit juices or soft drinks run a greater risk of putting on weight and developing diabetes than women who keep the syrupy drinks to a minimum, according to a U.S. study.
The study in the current issue of the Journal of the American Medical Association
The research was part of a study of 91,000 female nurses participating in the second phase of the Nurses' Health Study, based at Brigham and Women's Hospital
A total of 741 women developed type II diabetes, also known as adult-onset diabetes, during the 1991-1999 study period.
The researchers found that women who drank sugared fruit punch at least once a day were twice as likely as those who drank it less than once a month to develop type II diabetes.
And women who drank one or more sugary soft drinks a day had an 80% increased risk of developing compared with women who drank less than one sugary drink a month.
Women who drank large amounts of soft drink also piled on the kilos. Women who went from drinking one or fewer soft drinks a week to one or more soft drinks a day put on an average of four to five kilograms over four years.
"Soft drinks are the leading source of added sugar in the American diet. They provide a large amount of excess calories and no nutritional value," said Dr Matthias Schulze, the lead study author.
"Our results show that increasing one's consumption of sugary soft drinks significantly increases the risk for weight gain and type II diabetes," said Schulze, who was a research fellow in the nutrition department at Harvard School of Public Health
