What do we know about other sweeteners?
There is an array of artificial sweeteners on the market, with varying chemical structures. Data on their long-term health effects is lacking.
There’s no clear “winner” that is the best for you, said Joanne Slavin, a professor of food science and nutrition at the University of Minnesota-Twin Cities.
In the spring, the W.H.O. said that artificial sweeteners like aspartame, stevia, sucralose and saccharin may not help people lose body fat and that consuming them might be associated with a greater risk of cardiovascular disease, diabetes and overall mortality. Erythritol, a zero-calorie sugar substitute, has recently come under scrutiny for its potential links to cardiovascular issues, although that evidence is inconclusive.
Some health experts recommend phasing out artificial sweeteners from your diet altogether, as challenging as that may be. “If they don’t do any good, and they’re not required in the diet, and there’s no real advantage — why bother with them?” said Marion Nestle, a professor of nutrition, food studies and public health at New York University.
But sugar comes with concerns, too. Anything that consistently spikes your blood sugar can be a problem, especially if you have diabetes or another metabolic disorder. The Centers for Disease Control and Prevention has linked the frequent consumption of sugar-sweetened beverages, like regular sodas, with Type 2 diabetes, cardiovascular disease, kidney diseases, obesity and other health concerns.
“There’s always risk,” Dr. Slavin said. “In the end, if you can stand the calories, maybe a little bit of sugar in lemonade is better than an alternative sweetener. That’s your call, depending on your health status and what you want to do.”
