**Alcohol** affects people in different ways, and several factors influence the **blood alcohol concentration**, which is the amount of alcohol in the blood. One of these factors is whether one has eaten before drinking.

- **Eating before drinking** causes alcohol to be absorbed more slowly into the body. This means that, although the stomach is full, alcohol takes longer to reach the blood, temporarily reducing the blood alcohol concentration.

- However, even though alcohol is absorbed more slowly, **it does not eliminate the risk of an accident**. Alcohol still affects the brain and vision, which can lead to traffic accidents.

Therefore, having a full stomach influences the blood alcohol concentration by slowing down the absorption of alcohol, but it does not eliminate the dangers associated with alcohol consumption when driving.
