Reason 1: they don’t contain calories. Believe it or not Artificial sweeteners are compounds that offer the sweetness of sugar without the same calories. The catch? None! Each gram of table sugar contains 4 calories. Many sugar substitutes have zero calories per gram. This was all found in a 2017 study.
Reason 2: they don’t cause cancer According to the National Cancer Institute, there's no scientific evidence that any of the artificial sweeteners approved for use in the U.S. cause cancer. "The cancer risks are not something that an individual person should worry about," says Michael F. Jacobson, PhD, founder and chief scientist in Washington D. C. Why are we told they do? “It's more a risk for the government as the potential problems occur when millions of people consume the sweeteners for years.”
