The blue zone diet: Foods and habits for a longer life

The blue zone diet is a lifestyle-based eating pattern inspired by the lifestyles of the world's longest-lived populations. It's not just a diet but a holistic approach to health that focuses on the combination of diet, physical activity, social engagement and stress management.

The concept of the blue zone diet stems from the work of National Geographic Fellow and bestselling author Dan Buettner, who identified five regions in the world where people live significantly longer and healthier lives.

Ikaria, Greece: Located in the Aegean Sea, Ikaria is known for its low rates of chronic diseases and high life expectancy. The Ikarian diet is rich in vegetables, whole grains, legumes and olive oil, with moderate consumption of dairy products and alcohol.

Okinawa, Japan: The residents of Okinawa have the world's highest percentage of centenarians. Their diet consists of nutrient-dense foods like sweet potatoes, vegetables, tofu and seafood, along with limited meat consumption.

Sardinia, Italy: Sardinia boasts one of the highest concentrations of male centenarians. The traditional Sardinian diet includes whole-grain bread, beans, garden vegetables, fruits and moderate wine consumption.

Nicoya Peninsula, Costa Rica: The Central American region has a lower risk of heart disease and a longer life expectancy. The Nicoyan diet primarily features beans, corn, squash and tropical fruits.

Loma Linda, California, USA: Loma Linda is a unique Blue Zone within a predominantly Blue Zone-unfriendly environment. The residents here live longer than the average American, thanks to their largely plant-based diets, rich in nuts, fruits and vegetables.

While the blue zone diet emphasizes whole, plant-based foods, there are certain foods inhabitants of blue zones tend to avoid:

Processed foods: Blue Zone populations stay away from processed foods, which are typically high in unhealthy fats, added sugars and artificial ingredients.

Sugary beverages: Soda, energy drinks and other sugary beverages are rarely consumed in blue zones. Instead, water and herbal teas are the preferred choices.

Red and processed meat: Blue Zone inhabitants generally eat meat in moderation and usually prefer lean, unprocessed options when they do consume it.

Excessive dairy: While some blue zone diets include moderate amounts of dairy, it's not a primary food source. High-fat dairy products are generally limited.

Refined grains: Blue zone populations prioritize whole grains like brown rice, quinoa and whole wheat, while refined grains like white rice and white bread are avoided.
