Plasma concentrations of sucralose in children and adults.

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.
