Sucralose and cancer: is there a connection?

Many consumers have expressed concerns about the carcinogenic effects of artificial sweeteners on the human body. It was this factor that prompted scientists to study sucralose and its effect on humans.
Sucralose is a type of artificial sweetener widely used in the production of drinks, desserts, and confectionery. Sweetener has a number of advantages over real sugar:

  • Low calorie
  • Does not cause dental caries
  • Does not interact with other nutrients
  • Does not stimulate the production and release of insulin
  • Has good taste characteristics.
  • Many consumers question the safety of sucralose. Although most scientific evidence suggests that the sweetener does not pose a danger to the human body and does not cause cancer.

The essence of sucralose

This type of artificial sweetener is commonly used in low-calorie desserts and drinks, including coffee and tea. By the way, sucralose is the only artificial sweetener made from real sugar molecules. Scientists have discovered that if you replace one part of a sugar molecule with chlorine, you get a substance that is 600 times sweeter than classic sugar. In addition, it contains no calories and practically does not break down in the body.

Security Research

Concerns about a possible link between artificial sweeteners and cancer first arose when two other artificial sweeteners, cyclamate and saccharin, were found to cause bladder cancer in animals when used together. However, the US National Cancer Institute notes that there is no direct evidence that any artificial sweeteners cause cancer in humans.

Before the Food and Drug Administration (FDA, USA) approved sucralose for use, more than 100 safety studies were conducted. The research results are clear: sucralose does not pose any risk to human health and has no connection with the development of cancer.

Animal studies

Studies revealing a link between sweeteners and cancer have not been conducted in humans. But there is a 2013 laboratory experiment that revealed a possible link between sweetener and leukemia in mice. As a result of this study, the status of sucralose was changed from “safe” to “avoid”. At least until the results of the experiment are re-evaluated.

According to experts, sucralose is much safer than analogues such as saccharin, aspartame and acesulfame potassium. NYU Langone Medical Center notes that sucralose underwent more than 20 years of scrutiny by various regulatory agencies before it was approved for use. At this point, it is safe to say that there is no known connection between artificial sweetener and cancer in humans.
