Animal experiment:

Sucralose is pulverized in a standard pelleted diet at concentrations 0, 500, 2,000, 8,000, and 16,000 ppm and is administered to five groups of male (n=117, 114, 90, 66, and 70, respectively) and five groups female (n=102, 105, 60, 65, and 64, respectively) Swiss mice from the 12th day of fetal life until death[1].

Sucralose is an intense organochlorine artificial sweetener.

The results show that Sucralose induces significant increased incidence of all hematopoietic neoplasias in male mice exposed to 2,000 (p≤0.01), and 16,000 ppm (p≤0.01), with a significant dose-related relationship (p≤0.01). Microscopically, most of the neoplasias among male mice treated with Sucralose at 2,000 to 16,000 ppm are leukemias involving lungs, liver, spleen, lymph nodes, and bone marrow with diffuse permeation of vessels and extensive infiltration of adjacent tissues[1].
