Inside The Diets Of World's Healthiest People—And What I Was Doing Wrong

When I first discovered the concept of Blue Zones, I was left surprised. I couldn’t help but wonder—what were these people doing right that I wasn't? As I delved deeper into their lifestyles, one major difference stood out-their diet and food choices, While I often skipped sweet potatoes, they embraced them. And while processed foods made up a large part of my routine, Blue Zone residents avoided them altogether.

Blue Zones are geographical regions with a longer life expectancy and lower rates of chronic diseases. Identified by American explorer Dan Buettner, these "longevity centres" house people who follow specific diet and lifestyle practices that help them live past 100 years.

The five Blue Zones are:

• Okinawa, Japan
• Sardinia, Italy
• Nicoya Peninsula, Costa Rica
• Ikaria, Greece
• Loma Linda, California, USA

So What's Special In The Diets Of People From Blue Zones

1. Okinawa, Japan

The Okinawan diet is rich in vegetables, tofu, and sweet potatoes. They practice "Hara Hachi Bu," eating until they’re 80% full, which helps prevent overeating. The diet is low in calories and high in nutrients, with an emphasis on plant-based foods like bitter melon, goya, and seaweed.

2. Sardinia, Italy

In Sardinia, the diet is rooted in whole grains, beans, vegetables, and fruits, with moderate consumption of wine. They consume plenty of fava beans, chickpeas, and barley, which are packed with fibre and protein. Meat is eaten sparingly, often as a side dish rather than the main course.

3. Nicoya Peninsula, Costa Rica

Nicoyans enjoy a diet rich in beans, corn, and squash, known as the “three sisters.” Their meals are simple but nutrient-dense, with a strong reliance on plant-based foods. They also consume a lot of tropical fruits, providing antioxidants and vitamins that support longevity.

4. Ikaria, Greece

The Ikarian diet is a variation of the Mediterranean diet, focusing on vegetables, whole grains, and olive oil. Ikarians consume plenty of wild greens, herbs, and legumes. Their diet is also low in processed foods and sugars, which helps in maintaining heart health and reducing inflammation.

5. Loma Linda, California, USA

Loma Linda is home to a community of Seventh-day Adventists who follow a plant-based diet. Their diet emphasizes whole grains, nuts, fruits, and vegetables while avoiding meat and processed foods. This diet, combined with a strong sense of community and faith, contributes to their longevity.

Each Blue Zone diet is unique but shares common themes: a plant-based focus, moderate food intake, and the consumption of natural, whole foods. These dietary practices, along with an active lifestyle and strong social connections, are key to the remarkable longevity observed in these regions.
