Effect of Protein and Retinol on Alcohol-induced FGF21

Not Applicable

Completed

• Conditions: Healthy
• Interventions: Other: Retinol; Other: Alcohol; Other: Alcohol+retinol; Other: Alcohol+protein

• Registration Number: NCT06105476
• Lead Sponsor: University of Copenhagen

Brief Summary

The aims of this study are two-fold. First to investigate the influence of protein on the FGF21 response induced by alcohol, and second to investigate the influence of retinol on FGF21 concentrations and the FGF21 response induced by alcohol. Exploratory, and in order to investigate mechanisms behind the potential influence on alcohol-induced FGF21 response from protein or retinol intake, plasma glucose, insulin, glucagon, ethanol, acetaldehyde, acetate, retinol, retinoic acid, as well as subjective rating of appetite, will be measured.
