RODERO, Ademir B et al. Effects of Sucralose Ingestion on Fetal and Placental Weights and Umbilical-Cord Length: Experimental Study. Int. J. Morphol. [online]. 2010, vol.28, n.3, pp.823-827. ISSN 0717-9502.

Sucralose is a sweetener of general use in over three thousand products (beverages, foods and medical diets), with utilization currently permitted for the general population in more than 80 countries, including for women of reproductive age. There is little information on the safe use of sucralose, and experimental studies have suggested that the administration of some sweeteners, by diverse routes, retards not only fetal and placental development but also umbilical cord size. The present study aimed to estimate the fetal and placental weights and umbilical-cord length in fetuses from rat dams, after ingestion and non-ingestion of sucralose. In the treated group (5 dams), sucralose was administered (via gavage) at the dose of 30 mg/kg/day, from the 10th to 14th day of pregnancy. In the control group (5 dams), saline solution was administered, at the same dose and by the same route. On the 20th gestation day, both groups were sacrificed for weighing of the fetuses and placentas and measurement of umbilical-cord length. Mean values of fetal weight and umbilical-cord length of the treated group were significantly lower than controls (Mann-Whitney Test, p<0.001). Placental weight did not differ statistically between treated and control groups. It can be concluded from the present work that sucralose ingestion at 30 mg/kg/day, from days 10 to 14 of pregnancy, diminished fetal weight and umbilical-cord length, which suggests passage of sucralose through the placental membrane.
