The Blue Zones Diet is a plant-predominant eating pattern characterized by high intake of whole grains, legumes, fruits, and vegetables, with minimal processed foods, added sugars, and animal products. This dietary approach is associated with longevity and reduced chronic inflammation, improved metabolic health, a healthy gut microbiome, and provides a rich array of micronutrients and polyphenols. It is associated with lower rates of cardiovascular disease, cancer, and neurodegenerative conditions, all of which contribute to a longer healthspan.
Verdict
