Plasma concentrations of sucralose in children and adults.

ABSTRACT: Sucralose is partially absorbed after oral ingestion, with the majority excreted in the feces. We aimed to measure plasma sucralose concentrations following ingestion of doses reflecting a range of consumption (from one can of diet soda up to multiple sodas over the course of a day) and to compare concentrations in children and adults. Eleven adults (7 females, 4 males) consumed 355 mL water containing 0 mg sucralose (control) or 68, 170, or 250 mg sucralose (equivalent to 1-4 diet sodas). A second group of adults (n=11, 6 females and 5 males) consumed 355 mL Diet Rite Cola™ (68 mg sucralose and 41 mg acesulfame-potassium (ace-K)) or 68 mg sucralose and 41 mg ace-K in seltzer. Beverages were provided at separate visits in randomized order, prior to an oral glucose tolerance test. Eleven children (7 females and 4 males) consumed 0 or 68 mg sucralose in 240 mL water, in an identical study design. Blood was collected before beverage ingestion and serially for 120 min. Sucralose doses (corrected for weight) resulted in similar plasma concentrations in children and adults. Children reached peak concentrations of 145-400 ng/mL after 68 mg (mean 262.3 ± 24.6 ng/mL). Most adults reached similar peak concentrations (200-400 ng/mL after 250 mg (365.6 ± 69.9 ng/mL)) with the exception of two adults (1520 ng/mL and 1557 ng/mL, respectively). Concentrations were comparable whether sucralose was administered in water, combined with ace-K, or in diet soda. Due to their lower body weight and blood volume, children have markedly higher plasma sucralose concentrations after consumption of a typical diet soda, emphasizing the need to determine the clinical implications of sucralose use in children.

Project description:Background: Low-calorie sweeteners (LCSs) are found in many foods and beverages, but consumers may not realize their presence, and their role in appetite, weight, and health is controversial. Although consumption limits based on toxicologic safety are well established, the threshold required to exert clinically relevant metabolic effects is unknown.Objectives: This study aimed to determine whether individuals who do not report consumption of LCSs can be correctly characterized as "unexposed" and to investigate whether instructions to avoid LCSs are effective in minimizing exposure.Design: Eighteen healthy 18- to 35-y-old "nonconsumers" (<1 food or beverage with LCSs/mo) enrolled in a 2-wk trial designed to evaluate the effects of LCSs on the gut microbiota. The trial consisted of 3 visits. At baseline, participants were counseled extensively about avoiding LCSs. After the run-in, participants were randomly assigned to consume diet soda containing sucralose or carbonated water (control) 3 times/d for 1 wk. Food diaries were maintained throughout the study, and a spot urine sample was collected at each visit.Results: At baseline, 8 participants had sucralose in their urine (29.9-239.0 ng/mL; mean ± SD: 111.4 ± 91.5 ng/mL). After the run-in, sucralose was found in 8 individuals (2 of whom did not have detectable sucralose at baseline) and ranged from 25.0 to 1062.0 ng/mL (mean ± SD: 191.7 ± 354.2 ng/mL). Only 1 participant reported consumption of an LCS-containing food before her visit. After the intervention, sucralose was detected in 3 individuals randomly assigned to receive carbonated water (26-121 ng/mL; mean ± SD: 60.7 ± 52.4 ng/mL).Conclusions: Despite the selection of healthy volunteers with minimal reported LCS consumption, more than one-third were exposed to sucralose at baseline and/or before randomization, and nearly half were exposed after assignment to the control. This shows that instructions to avoid LCSs are not effective and that nondietary sources (e.g., personal care products) may be important contributors to overall exposure. This trial was registered at clinicaltrials.gov as NCT02877186.
