Does eating slow down the absorption of alcohol in blood stream?

Yes, it does.

When alcohol is consumed on an empty stomach, it is absorbed more rapidly compared to when consumed with food. Food, especially food high in fat and protein, can slow down the absorption of alcohol into the bloodstream. This is because food causes the stomach to take longer to empty its contents into the small intestine. The slower the stomach empties, the slower the alcohol is absorbed.

In addition, food can also help to reduce the peak blood alcohol concentration (BAC). This is the highest level of alcohol in the blood that is reached after drinking. A lower BAC can help to reduce the risk of alcohol-related problems, such as impaired judgment, accidents, and injuries.

For these reasons, it is recommended to eat before or while drinking alcohol. Eating a meal that is high in fat and protein can help to slow down the absorption of alcohol and reduce the risk of alcohol-related problems.
