A new study of sweetened beverages shows that cane sugar and high fructose corn syrup have similar effects on hunger, fullness, and food consumption at lunch. According to the study, which appears in the July issue of the American Journal of Clinical Nutrition, this may be because sucrose (table sugar) in beverages splits into glucose and fructose molecules, such as are present in high-fructose corn syrup. The results suggest that while appetite and food intake are influenced by the number of calories consumed earlier, the types of sugars consumed in those calories seem to make little or no difference.
Some companies have made a sincere effort to put sucrose back in soda, said Dr. Adam Drewnowski, director of the Nutritional Sciences Program at the University of Washington and the senior author of the study. But there is no direct link between the type of sweetener and obesity. As far as appetite is concerned, cane and corn sugars in beverages are much the same."
The study is authored by Dr. Pablo Monsivais, research fellow in the UW Nutritional Sciences Program, and co-authored by Drewnowski and UW graduate student Martine Perrigue.
The Seattle investigators provided subjects with a beverage mid-morning, then tracked hunger, appetite and thirst for two hours, and then gave the study participants lunch. Cola beverages sweetened with sucrose or with two different types of high-fructose corn syrup were compared to an aspartame-sweetened diet cola, milk (1 percent fat), and to a no-beverage control group. Lunch consisted of a wide variety of savory and sweet foods, accompanied only by plain water. Each participant went through separate tests for each type of beverage over the span of several weeks.
Study participants who drank a non-caloric diet cola ate about the same amount at lunch as when they had no beverage at all. Participants ate somewhat less at lunch after drinking any of the caloric beverages, but only partially compensated for the c
