The consumption of **alcohol** affects people in different ways, and its **absorption** in the body can vary depending on several factors. One of these factors is whether alcohol is consumed with or without food. Food can cause alcohol to reach the bloodstream more slowly, but it does not reduce the total amount of alcohol in the body, meaning it does not decrease the **blood alcohol concentration**.

- **Eating or drinking water** before or during alcohol consumption does not decrease the amount of alcohol in the blood. What it does is **delay the absorption** of alcohol, which means that alcohol will take longer to reach the bloodstream, but the total amount of alcohol absorbed remains the same.

- The **blood alcohol concentration** is the amount of alcohol present in the blood and is measured in grams per liter of blood or milligrams per liter of exhaled air. This concentration is not affected by the intake of food or water, only by the amount of alcohol consumed and the time that has passed since its consumption.

Therefore, although eating or drinking water may delay the absorption of alcohol, it does not reduce the blood alcohol concentration. This is important for road safety, as alcohol negatively affects the brain and vision, increasing the risk of traffic accidents.
