Non-nutritive sweeteners are ineffective for weight management, and routine consumption may in fact lead to several risks.
That’s according to a sweeping study by a team of medical researchers, who have compared the results of seven trials and 30 cohort studies.
The study was initiated because of the uncertainty surrounding the long-term health impact of sweeteners like aspartame, sucralose and stevioside.
Researchers considered body mass index (BMI) and several cardiometabolic factors in their assessment.
In the seven trials, BMI was not significantly effected by the consumption of sweeteners. Interestingly, however, the cohort trials suggested that “consumption of nonnutritive sweeteners was associated with a modest increase in BMI”.
The cohort studies also suggest that there are other risks involved with the intake of non-nutritive sweeteners.
“In the cohort studies, consumption of nonnutritive sweeteners was associated with increases in weight and waist circumference,” researchers say, “and higher incidence of obesity, hypertension, metabolic syndrome, type 2 diabetes and cardiovascular events.”
The study concludes that there is no evidence for the intended benefits of such sweeteners. Quite the contrary - they may be more harm to you than good.
Researches admit that more research is needed, but the study does at least encourage consumers to proceed with caution.
