A new University of Manitoba study says artificial sweeteners are linked to the risk of long-term weight gain, heart disease and other health issues.

The study was published in the Canadian Medical Association Journal.

It says more people are eating and drinking artificial sweeteners like aspartame, sucralose, and stevia.

The university found that new data indicates artificial sweeteners may have a negative effects on metabolism, gut bacteria and appetite.

"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 in a news release.

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

The research reviewed 37 studies that followed over 400-thousand people for an average of 10 years.

Until the long-term effects of artificial sweeteners are proven, the study recommends people be cautious about how much they are eating and drinking.
