Some savor alcohol during meals, while others opt for a digestif afterward to cap off a hearty feast. But does this tradition truly support digestion?
After a heavy meal, steer clear of fruit, tea, swimming, sports, cigarettes, or napping. Should digestifs join this list? Spirits like cognac, whisky, armagnac, aged rum, or calvados are often enjoyed post-meal to ease indulgences.
In truth, it's simply a misconception, as shown by studies including one from 2010 at University Hospital Zurich (Switzerland). Lead researcher Henriette Heinrich found that alcohol during the meal halved gastric digestion speed. Water drinkers digested in six hours versus nine hours for alcohol consumers. Note: this involved alcohol with the meal (a Savoyard fondue).
Experts agree: science has long debunked the notion that alcohol aids digestion by boosting gastrin secretion, an enzyme meant to enhance stomach motility. While alcohol causes vasodilation—distending the stomach for a fleeting sense of relief—it ultimately hinders the process.
Alcohol passes through the digestive tract unchanged, absorbing directly into the bloodstream via the stomach and intestines. This can trigger diarrhea. Beyond short-lived vasodilation—a falsely beneficial effect—no advantages exist for consuming it during or after meals. Historically, digestifs gained fame from added aromatics and spices that did aid digestion.
Proven alternatives include drinking water to break down food, chewing thoroughly, and taking a gentle post-meal walk. A short stroll lightly stimulates the body and digestive system.
