Health concerns linked to sugar substitutes

Health agencies have clarified that sugar substitutes do not cause serious health problems.

Sugar substitutes also are not linked to a higher risk of cancer in people. Studies dating back to the 1970s linked the artificial sweetener saccharin to bladder cancer in rats. Since then, research has shown that those findings don't apply to people.

Some research on long-term, daily use of artificial sweeteners suggests a link to a higher risk of stroke, heart disease and death overall. But other things people do, or healthy habits that people don't do, may be the cause of the higher risk.

Other research is looking at long-term use of sugar substitutes and the gut. Many focus on how the gut and brain communicate. Researchers are checking to see if sugar substitutes affect cravings for sweets, the way people feel hunger and how the body manages blood sugar.

Sugar alcohols, stevia and luo han guo can cause bloating, gas and diarrhea. The amount of sugar alcohol that causes these symptoms varies from person to person.

In general, it is safest to take in small amounts of sugar substitutes. And it's best to use sugar substitutes for a short time, or just every once in a while. So try to cut back if you use them a few times a day.
