The World Health Organization issued a startling new report urging people to cut artificial sweeteners and other sugar substitutes from their diets. But that doesn’t mean you should switch back to using real sugar, the agency said. WHO has already issued guidelines urging people to limit the amount of sugar they eat. Now the agency wants people to cut back on all sweeteners, period — whether they’re natural or artificial.

“Treat them as an element of the diet which we should discourage,” said Francesco Branca, the director of the Department of Nutrition for Health and Development at the WHO. “Sugar sweeteners do not belong to a healthy diet. That’s what we want to say.”

The guidance applies to individual sweetener packets that people may add to food and drinks as well as ultra-processed foods that contain the sweeteners. This list includes Acesulfame K, Aspartame, Advantame, Cyclamates, Neotame, Saccharin, Sucralose, and Stevia (and stevia derivatives).  Monk fruit extract isn’t on the list of sweeteners from WHO. It’s a relatively new addition to packaged foods. So, there’s less research available on its long-term effects. That said, “it is likely” that monk fruit extract may act the same as other sweeteners, Branca said.
