Acesulfame-K

An artificial sweetener, acesulfame-K is produced with methylene chloride, which has carcinogenic effects on the thyroid and liver and causes nausea, mood problems, and impaired eyesight. Acesulfame-K is the least studied artificial sweetener, so more potentially hazardous effects may not have been discovered yet. For this reason, it’s best to avoid this sweetener until we know more.

As with all artificial sweeteners, acesulfame-k can’t be broken down by the body, which negatively affects metabolism. Avoid sugar-free foods like chewing gums and diet sodas.
