Alcohol in Blue Zones

Alcohol is part of life in some Blue Zones, but in a special way. It is not about drinking a lot. Instead, drinking is moderate and social.
For example, in Sardinia, people drink a little red wine with meals and friends. This helps social bonds and may offer health benefits from antioxidants.
In Ikaria, people also drink wine in small amounts during family meals. This is part of their relaxed lifestyle.
However, in Loma Linda, many people do not drink alcohol at all. Their faith encourages abstaining from alcohol.
So, alcohol in Blue Zones is about moderation and sharing, not heavy drinking.
