Blue Zones Diet: Overview, Benefits, and Meal Plan

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.

The assumption is that diet alone plays a significant role in the longevity observed in these regions, according to a 2022 study by Giovanni Mario Pes from the University of Sassari. The concept of blue zones originated from demographic work by Gianni Pes and Michel Poulain in 2004. 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.
