Artificial Sweeteners Linked to Obesity, Heart Disease and Diabetes

Posted August 16th, 2017 in Uncategorized by Luke

Artificial sweeteners may be associated with long-term weight gain and increased risk of obesity, diabetes, high blood pressure and heart disease, according to a new study published in CMAJ (Canadian Medical Association Journal)

Consumption of artificial sweeteners, such as aspartame and sucralose , is widespread and increasing. Emerging data indicate that artificial, or nonnutritive sweeteners may have negative effects on metabolism, gut bacteria and appetite.

To better understand whether consuming artificial sweeteners is associated with negative long-term effects on weight and heart disease, researchers from the University of Manitoba’s George & Fay Yee Centre for Healthcare Innovation conducted a systematic review of 37 studies that followed over 400,000 people for an average of 10 years.

 The longer observational studies showed a link between consumption of artificial sweeteners and relatively higher risks of weight gain and obesity, high blood pressure, diabetes, heart disease and other health issues.

The trials did not show a consistent effect of artificial sweeteners on weight loss.

“Despite the fact that millions of individuals routinely consume artificial sweeteners, relatively few patients have been included in clinical trials of these products,” said author Dr. Ryan Zarychanski, Assistant Professor, Rady Faculty of Health Sciences, University of Manitoba.

“We found that data from clinical trials do not clearly support the intended benefits of artificial sweeteners for weight management.”

“Caution is warranted until the long-term health effects of artificial sweeteners are fully characterized,” said lead author Dr. Meghan Azad, Assistant Professor, Rady Faculty of Health Sciences, University of Manitoba.

“Given the widespread and increasing use of artificial sweeteners, and the current epidemic of obesity and related diseases, more research is needed to determine the long-term risks and benefits of these products,” said Azad.
