Question

Milk or a fatty snack taken prior to the ingestion of alcohol decreases the rate of intoxication. What is the mechanism of this effect?

Answer 1

Milk or a fatty snack taken prior to the ingestion of alcohol decreases the rate of intoxication mainly because fats and proteins in these foods delay the absorption of alcohol from the stomach into the bloodstream. Specifically, these foods:

• Slow down gastric emptying rate, so the alcohol remains longer in the stomach.
• In the stomach, alcohol is partially metabolized by the enzyme alcohol dehydrogenase before absorption, so delaying its passage to the intestine reduces and slows its absorption.
• Fatty foods form a coating or lining on the stomach mucosa, thereby reducing the direct contact and absorption of alcohol.
• This results in a slower rise in blood alcohol concentration, diminishing the immediate intoxicating effects.

Therefore, consuming milk or fatty snacks before drinking alcohol acts as a protective measure by reducing the rapid entry of alcohol into the circulatory system and the brain, thereby decreasing the intensity and rate of intoxication.
