Based on the literature and discussions I've had with experts like Dr. Peter Attia, there is no dose of ethanol that is healthy. While there may be no measurable harm for most people consuming one drink per day, the risk starts to climb steeply after that. It's also important to note that alcohol consumption, even in moderate amounts, has been shown to reduce cortical thickness in the brain. This effect scales with the amount of alcohol consumed. Some more conservative views suggest limiting consumption to two drinks per week to avoid potential health risks. My personal view is that if you can avoid drinking alcohol at all, you're better off. However, if you do choose to drink, be aware of the potential negative health effects and consider ways to offset them.
