Led by Allison Sylvetsky of Emory University in Atlanta, the researchers suggested several possible reasons for the increase in consumption of sugar-free soft drinks, including obesity prevention campaigns, increased negative health associations of excessive sugar consumption in recent years, or increased prevalence of type 2 diabetes. However they added that further research was necessary to determine the health effects of low-calorie sweetener consumption on young children, if any.
“Given recent discussions of taxing sugar-sweetened beverages and banning regular sodas in school systems and the growing popularity of differential pricing structures to promote healthier choices, it can be anticipated that LCS [low-calorie sweetener] consumption will increase further,” they wrote. “Most importantly, given the rapid increases in LCS consumption among children, their long-term effects, particularly when started in the early years, need to be studied.”
Calling for further research into artificial sweetener consumption and weight management, they cite previous research that has suggested a correlation between higher consumption of artificially sweetened soft drinks and increased prevalence of overweight and obesity. However, it is unclear whether artificial sweeteners actually cause weight gain, or whether overweight individuals are more likely to consume artificially sweetened drinks in an effort to control their weight.
While the study’s authors found increased consumption of sugar-free soft drinks, they found little change in consumption of foods containing low-calorie sweeteners between the two periods they examined.
