Sweetened beverages associated with a higher risk of diabetes

According to a recent study, fruits and other foods containing fructose do not seem to have a detrimental effect on blood sugar levels, while sweetened beverages and foods that add excess energy to diets can have negative effects.

The study appeared in BMJ magazine. The role of sugars in the development of diabetes and heart disease attracts widespread debates, and rising data suggest that fructose can be particularly harmful to health.

"These findings can help make recommendations for important dietary sources of fructose in the prevention and treatment of diabetes," said the author of the study and Dr. John Sievenpiper.

Fructose is naturally found in a range of foods including whole fruits and vegetables, natural fruit juices and honey. It is also added to foods such as soft drinks, cereals, baked goods, sweets and desserts as "free sugars". The current diet guidelines recommend reducing free sugars, especially fructose from sweetened beverages, but it is not clear whether this applies to all food sources of these sugars.

Researchers based in San Francisco and the University of Toronto, Canada, analyze the results of 155 studies evaluating the effect of various food sources on fructose sugars on blood sugar levels in people with and without diabetes observed for up to 12 weeks.

The results are based on four projects: substitution (comparison of sugars with other carbohydrates), addition (energy from sugars added to the diet), subtraction (energy from sugars removed from the diet) or adilibitum (energy-substituted sugar).

The results were glycated hemoglobin or HbA1c (amount of red blood cell glucose), fasting glucose and fasting insulin (blood glucose and insulin levels after a fasting period).

The results show that most foods containing fructose sugars have no harmful effects on blood sugar levels when these foods do not provide unnecessary calories. However, some studies have seen a detrimental effect on fasting insulin.

Analysis of certain foods suggests that fruit and fruit juice, when these foods do not provide extra calories, can have a beneficial effect on blood glucose and insulin control, especially in people with diabetes, while several foods that add excess "especially sweetened beverages and fruit juice, seem to have harmful effects.

The low glycemic index (GI) of fructose compared to other carbohydrates and higher fiber content in fruit can help explain improvements in blood sugar levels by slowing down the release of sugars, according to researchers. (ANI)
