Is Moderate Drinking Okay?
2 days ago
- Moderate drinking's health effects are confusing due to conflicting studies, with recent reports linking alcohol to cancer risk and others suggesting longer life.
- The 'J curve' theory, suggesting moderate drinking reduces mortality, is flawed due to biased comparisons between moderate drinkers and unhealthy nondrinkers.
- Many studies on alcohol and health suffer from poor data, confounding variables, and overconfident conclusions, making it hard to draw clear answers.
- Alcohol's cancer risk is often overstated in relative terms; absolute risks (e.g., mouth cancer increases by 0.3 percentage points) are low for moderate drinkers.
- Life expectancy reduction from moderate drinking (about 5 minutes per drink) can be offset by exercise, but social benefits of alcohol should also be considered.
- Declining alcohol consumption among Americans, especially youth, may reduce addiction risks but also reduce face-to-face socializing, which is valuable for well-being.
