The Blue Zones Diet refers to the eating habits followed by populations living in Blue Zones, which are regions known for having a higher prevalence of centenarians and longer life expectancy. The Blue Zones include Okinawa in Japan, Ikaria in Greece, Sardinia in Italy, Nicoya in Costa Rica, and a region in the United States.

In this article, we will dive into the details of the Blue Zones Diet, exploring its benefits and providing you with a sample meal plan to get you started on your journey to well-being.
