The Claim

Acesulfame-K, advantame, aspartame, cyclamate, neotame, steviol glycosides, and sucralose do not exhibit genotoxic or carcinogenic potential, and there is no reproducible evidence of tumor formation or DNA damage at doses exceeding human exposure levels.

Description
1 study reviewed
In plain English

Seven artificial and natural sweeteners—acesulfame-K, advantame, aspartame, cyclamate, neotame, steviol glycosides, and sucralose—do not cause DNA damage or tumors, even at doses much higher than what people typically consume.

See the scientific wording

The weight of evidence from animal and mechanistic studies supports the conclusion that acesulfame-K, advantame, aspartame, cyclamate, neotame, steviol glycosides, and sucralose lack genotoxic and carcinogenic potential, with no reproducible evidence of tumor formation or DNA damage at doses far exceeding human exposure levels.

Why this might work

These sweeteners are broken down or passed through the body unchanged, never interacting with DNA or triggering cell damage that could lead to cancer. The body removes them quickly through urine or feces without creating harmful byproducts.

  1. Study: Lack of Genotoxic and Carcinogenic Potential for Nonsugar Sweeteners: A Review of Animal and Mechanistic Evidence

    Scientists looked at decades of animal studies on these artificial sweeteners and found no reliable proof they cause cancer or damage DNA—even when given in huge doses. So, there's no good reason to think they're harmful in the amounts people normally eat or drink.
