"Eating food is an important element in reducing drinking and reducing risk of intoxication," Garbutt said. Eat a meal before you take your first sip of alcohol, he advises, and continue to take in food as the night wears on. Food, fats especially, help slow down the body's absorption of alcohol. But to truly be effective, the food must be in your stomach first. If you wait until you're feeling buzzed or tipsy to start eating, it's already too late.
