'Artificial sweeteners may up obesity, heart disease risk'

Artificial Sweetener linked to obesity

Among the cohort studies, consumption of nonnutritive sweeteners was associated with increases in weight and waist circumference, as well as higher incidence of obesity, hypertension, metabolic syndrome, type 2 diabetes and cardiovascular events.

Scientists have compared and reviewed two types of scientific studies and have come to a unanimous conclusion that there is actually no solid evidence that artificial sweeteners help with weight loss or management.

MONDAY, July 17, 2017 (HealthDay News) - Artificial sweeteners may be less helpful than many believe in helping people lose weight and avoid health problems associated with extra pounds, a new evidence review suggests.

"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", she concluded.

In response to the April study, the Calorie Control Council said the research was not preliminary and doses were not "physiologically relevant", and noted that the study contradicts previous research that shows sucralose does not accumulate in the body.

In order to attribute the observation of higher obesity rates in frequent low calorie sweeteners' consumers to the use of low calorie sweeteners per se, rather than to some other unmeasured confounding factors, meaning to prove causation, a trial of randomised controlled design is required.




At her lab, Azad is now studying what happens when people are given artificially sweetened beverages for several weeks.

"I think the takeaway for Canadians at this point is to maybe think twice about whether you really want to be consuming these artificial sweeteners, particularly on an everyday basis", Azad said, "because really we don't have evidence to say for sure whether these are truly harmless alternatives to sugar".

They found no link between the use of artificial sweeteners and changes in body mass index (BMI), which is a measure of weight in relation to height, among the 1,003 people in the randomized controlled trials. Some turn to aspartame, sucralose or other artificial sweeteners to satiate their sweet tooth while losing weight.

Which is healthier: Artificial sweeteners or sugar? However, other experts say there's not enough evidence to recommend abstaining from these sugar substitutes, noting they're approved by Health Canada.

Do artificial sweeteners help us lose weight? Sales of diet soda drinks have dropped by almost 20% since 2009, according to market research group Euromonitor. Researchers wanted to look more broadly at what's going on by doing a large-scale analysis of dozens of studies on low-calorie sweeteners. The metabolism and fauna, and gut may also be affected by these sweet products that do not contain calories.

"It's possible that different sweeteners have different effects, but we were not able to examine that because of the studies available", she said.
