Alcohol Absorption and Metabolism

There are a lot of conflicting reports and myths about how we absorb, break down and metabolise alcohol, the different effects one type will have over another type and how we can prevent ourselves from getting too drunk. 

"Will drinking beer get you less drunk than drinking spirits?" 

"Eating a good meal before drinking will absorb most of the alcohol." 

Both of these "myths" have good merit on their surface. It makes sense to most people that the Alcohol concentration of beer is less per mL than vodka; therefore, won't get us as drunk. However; the average person is unlikely to consume a Pint of straight Vodka in one sitting. The more likely scenario is the consumption of Vodka mixed with a non alcoholic liquid. One of these mixed drinks, on average, will have the same alcohol concentration per mL as one Beer. 

"What about shots?" 

Research shows that the maximum absorption rate, on an empty stomach, is achieved at an alcohol concentration of ~25% and a concentration of 40% actually acts similarly to having a stomach full of food. This slows the emptying of our stomach into the small intestines (where 80% of alcohol ingested is absorbed into the bloodstream) which, in turn, slows the absorption of alcohol. 

The simple fact behind food and alcohol absorption is that there is a strong case behind foods absorbing liquid. However, when we break down the enzymes that are extracted from food and the ethanol, propanol or butanol compounds found in alcoholic drinks, these do not mix, cancel each other out or absorb each other. The number one thing food does is slow the process of absorption by slowing the emptying of the stomach in to the small intestines. 

"So what should I do when I go out?"

Drinking one 280mL Beer or one 30mL Vodka will both reach the same peak BAC (Blood Alcohol Concentration) this peak will still be reached whether we have a full stomach or not. 

Always enjoy alcohol in moderation to prevent excessive drunkenness.
