The British Medical Journal (BMA) did a review of published studies and found that there is no compelling evidence for health benefits of non-sugar sweeteners, and potential harms cannot be ruled out.
While society continues to grapple with the advice du jour of avoiding fats, sugars, carbs, gluten, dairy, meats, GMO foods, or anything with corn (or is it soy?) people have hedged their bets by opting for sugar-free sugar substitutes.
The researchers point out that this is the most comprehensive review on this topic to date and will inform a World Health Organization guideline for health 3experts and policymakers.
They concluded that "no good evidence of any effect of non-sugar sweeteners was found for overweight or obese adults or children actively trying to lose weight." The one bright side seems to be that non-sugar sweeteners may be an effective strategy to reduce chances of having diabetes, heart disease or stroke among heavy consumers of sugar-sweetened drinks, with the ultimate goal of switching to water or other health drinks."
