You may want to think twice about consuming artificial sweeteners again, according to a new study that connects them to long-term weight gain, increased obesity risk, and potential health dangers beyond one's waistline.
It says more people are eating and drinking artificial sweeteners like aspartame, sucralose, and stevia.
The findings showed that artificial sweeteners or non-nutritive sweeteners may have negative effects on metabolism, gut bacteria and appetite.
Assistant Professor Dr Ryan Zarychanski said: "We found that data from clinical trials do not clearly support the intended benefits of artificial sweeteners for weight management".
To test the correlation between artificial sweeteners with the health issues, the researchers had done a systematic analysis of 37 studies which followed more than 400 000 people for an average of 10 years.
"Caution is warranted until the long-term health effects of artificial sweeteners are fully characterized", said lead author Dr. Meghan Azad, whose team at the Children's Hospital Research Institute of Manitoba is also now looking into how consuming artificial sweeteners while pregnant may influence weight gain, metabolism and gut bacteria in children. Another study published earlier this year found that a quarter of US children and 41 percent of adults reported consuming them, majority once per day. But they did not find concrete proof of causation.
USA consumption of artificial sweeteners has increased dramatically over the past 15 years.
New Canadian research has found a link between artificial sweeteners and a range of health problems, including long-term weight gain and increased risk of obesity, diabetes, high blood pressure and heart disease.
Finally, your gut microbiome - a collection of hundreds of types of bacteria - is altered by artificial sweeteners.
To determine whether regular consumption of nonnutritive sweeteners is associated with long-term adverse cardiometabolic effects, Azad and colleagues searched several databases for randomized controlled trials (RCTs) that assessed interventions for nonnutritive sweeteners and cohort studies that evaluated the consumption of such sweeteners among adults and adolescents.

Artificial additives contain hazardous substances, which few people realize.
A recent study analyzed artificial sweeteners and discovered they might not be a sensible choice to replace sugar.
NIH pediatric endocrinologist Dr. Kristina Rother, who wasn't involved in the study, said it is a strong piece of work that highlights the need for more and better-designed studies on low-calorie sweeteners.
Other hypotheses suggest they promote a preference for sweetness, leading to further consumption of sweet foods and beverages, or may lead people to indulge in other ways. Artificial sweeteners were the product of the need to provide a sweet experience to the ones who were supposed to steer clear of natural sugar.
