Centenarians – people who live to be at least 100 years old – have drawn the attention of researchers from around the world. Many centenarians live in regions now called blue areas, including Loma Linda, California; Nicoya, Costa Rica; Sardinia, Italy; Ikaria, Greece; And Okinawa, Japan.
The researchers studied the eating habits of residents of the blue zone because the diet plays an important role in aging. While different foods can support overall health and longevity, research often highlights 10 foods that centenarians eat. These foods rich in nutrients promote overall health and support healthy aging.

Beans and legumes are an important part of the blue zone diet. They are rich in protein, fiber, vitamins and minerals.

Beans can also support your heart and digestive health. They contain soluble fibers, which slows digestion and supports beneficial bacteria in your intestine. This helps your body absorb more nutrients. It is also linked to bile acids in your digestive tract and helps reduce blood cholesterol, by supporting heart health.
Beans are rich in antioxidants and help fight oxidative stress (an imbalance in free radicals without enough antioxidants to neutralize them), which can cause inflammation and various chronic (long -term) diseases.
