Dan Buettner has spent decades studying the diets of the world’s longest-lived people in blue zones and he shares the one food that is a cornerstone of these healthy diets
A longevity expert has identified the superfood that is a ‘cornerstone of every blue zones diet. ‘ Dan Buettner, a National Geographic Fellow, has dedicated decades to studying ‘blue zones’, regions with the highest proportions of centenarians worldwide. He is also a New York Times bestselling author.
As part of his work, Buettner frequently responds to queries about his own diet and the lifestyle modifications he has adopted based on his research. Speaking to Meat Free Mondays, a non-profit campaign started by Paul, Mary, and Stella McCartney, the author shared why he opts for a meat-free diet.
He stated: “I’ve spent over 20 years studying the diets of the world’s longest-lived people in the blue zones. What I’ve seen consistently is that people who live the longest and healthiest lives eat mostly whole, plant-based foods with very little or no meat.”
Buettner also recommended a superfood that he consumes regularly. When asked to list the items perpetually present in his fridge, the author responded: “You’ll almost always find beans – black beans, lentils, or chickpeas – because they’re the cornerstone of every blue zones diet.”
He continued: “I keep a variety of fresh vegetables, leafy greens and herbs so I can throw together quick meals. There’s usually sourdough bread, some nuts and seeds, and a good bottle of olive oil too.”
Beans have long been a staple in the diets of those seeking a nutritious meal that keeps them satiated for longer periods. As per NHS guidance, beans are an excellent source of fibre and protein, reports the Mirror.
Packed with a variety of vitamins, nutrients, and minerals, beans can contribute to your recommended target of fruits and vegetables. If you choose green beans, such as runner beans or broad beans, which are classified as vegetables, they could count as an additional portion of your five a day.
The Cleveland Clinic, a non-profit, multi-speciality academic medical centre, even labels beans as ‘nutritional powerhouses’ and a ‘superfood’. The medical centre explains: “Eating beans can help lower cholesterol, maintain healthy blood sugar levels, fight cancer, promote digestive health and even help manage weight.”
Those who wish to increase their bean intake could do so by adding beans to salads, soups, stews, and chilis, or blending them into dips. They can also serve as a meat substitute in tacos or replace flour in baked goods. It’s advised to start with small portions and gradually increase them to minimise gas.
The NHS underscores that a healthy diet is a balanced one. It’s crucial to consume a variety of foods in the correct proportions. According to the Eatwell Guide, individuals should aim to:
