Summary

This study looked at whether drinking calvados (a strong apple brandy) during a high-calorie festive meal helps digestion, as some people believe. Eight healthy volunteers ate a standardized 1850-calorie meal and either drank calvados with sorbet or water with sorbet. Researchers measured how fast the stomach emptied using ultrasound and asked about discomfort and appetite. The goal was to see if the alcohol actually speeds up or slows down digestion.
