A Soda a Day Increases Risk of Type 2 Diabetes
New research published in Diabetologia (the journal of the European Association for the Study of Diabetes) suggests that drinking one-12 oz serving size of sugar-sweetened soft drink daily can increase the risk of developing type 2 diabetes by 22 percent. Most studies on these matters have been conducted in North America, but the authors, led by Dr Dora Romaguera, of the Imperial College London, UK, examined data from eight countries in Europe, participating in the European Prospective Investigation into Cancer and Nutrition (EPIC study, including UK, Denmark, Germany, Italy, Spain, France, Sweden, and the Netherlands).
The study included more than 12,000 cases of type 2 diabetes and a random group of more than 16,000 participants identified within EPIC. After adjusting for confounding factors, the researchers found that drinking one 12 oz serving size of sugar-sweetened soft drink a day increased the risk of type 2 diabetes by 22%, although this risk fell to 18% when total calorie intake and body-mass index (BMI) were considered. They think that this could indicate that the link between sugar-sweetened drinks and diabetes goes beyond its effect on body weight.
The investigators report that a significant increase in the incidence of type 2 diabetes was also related to regular drinking of artificially sweetened soft drink, although this association disappeared after taking into account the participants’ BMI. They think that this probably indicates that the link was not causal but affected by the weight of participants. Drinking of pure fruit juice and nectar was not significantly associated with the incidence of diabetes. However they could not use the data available to distinguish the effect of drinking 100% pure juices from those with added sugars.
