The Study
Low-calorie sweeteners in the human diet: scientific evidence, recommendations, challenges and future needs. A symposium report from the FENS 2019 conference
This report is like a teacher summarizing what several scientists said at a big meeting — it doesn’t do any experiments itself. So it can tell you what people think or what other studies found, but it can’t prove anything new.
Analysis score

Where the score came from
Sugar-free drinks with artificial sweeteners don't make you gain weight or spike your blood sugar like sugary drinks do. People use them to feel full and cut calories without guilt.

When people eat or drink things with low-calorie sweeteners like they normally do, studies show it doesn’t hurt their health.
Experts say that sugar substitutes like those in diet sodas are safe for everyone — even kids and pregnant women — as long as you don’t eat way more than normal amounts.
If you use sugar-free sweeteners instead of regular sugar, they won’t spike your blood sugar or insulin right away—and if you swap sugar for them in meals, they might even help keep your blood sugar lower after eating.
