Descrizione dettagliata
Non-nutritive sweeteners (NNS) are widely used as sugar substitutes in reduced-calorie foods and beverages. Among these, acesulfame potassium (Ace-K) is extensively incorporated into commercially available soft drinks because of its high sweetening potency, thermal stability, and minimal caloric contribution. Following oral ingestion, Ace-K is rapidly absorbed and excreted predominantly unchanged in urine, making it a promising biomarker of NNS consumption and dietary exposure. However, limited information is available regarding the urinary pharmacokinetics of Ace-K following consumption of commercially formulated beverages under free-living conditions.
Proton nuclear magnetic resonance (¹H NMR) spectroscopy enables simultaneous quantitative analysis of exogenous compounds and endogenous metabolites in complex biological samples. By applying the same analytical platform to both the intervention beverage and sequential urine samples, this study investigates the relationship between the ingested dose of Ace-K and its urinary excretion profile while simultaneously evaluating short-term metabolic responses following Coca-Cola Zero Sugar consumption.
This non-randomized, within-subject controlled study compares the urinary metabolomic response after consumption of Coca-Cola Zero Sugar with that observed following consumption of still water. The study aims to characterize the urinary appearance and elimination kinetics of Ace-K, quantify pharmacokinetic parameters including time to peak concentration and urinary elimination half-life, and explore acute changes in urinary metabolite profiles associated with Coca-Cola Zero Sugar consumption using quantitative ¹H NMR metabolomics.

Sperimentale: Coca-Cola Zero Sugar
Participants consumed 500 mL of Coca-Cola Zero Sugar with breakfast.
Spot urine samples were collected before beverage consumption and repeatedly over the subsequent 24-hour period for metabolomic and pharmacokinetic analyses using proton nuclear magnetic resonance (¹H NMR) spectroscopy.

Participants consumed a single oral dose of 500 mL Coca-Cola Zero Sugar with breakfast.
The intervention beverage was consumed within approximately 10-20 minutes.
Spot urine samples were collected before consumption and repeatedly over the subsequent 24-hour period for metabolomic and pharmacokinetic analyses using proton nuclear magnetic resonance (¹H NMR) spectroscopy.
