Explorer and educator Dan Buettner regularly shares tips and tricks to help people live longer.

The author and National Geographic fellow has become well known for his research into the world's 'blue' zones - the areas of our planet where people regularly live into their old age.

Buettner, 64, studies everything about these areas from factors like relationship dynamics and exercise to climate and diet.

One of these regions - the Nicoya Peninsula - has the "lowest rate of middle-age mortality in the world", according to the New York Times bestselling author.

Nicoyans are likely to live well past middle age which Buettner largely attributes to "the best diet human beings have ever invented."

"Their diet is composed of three foods that I would argue are the best diet human beings have ever invented," Buettner commented.

The explorer continued: "Because of these foods, the people living on the Nicoya Peninsula of Costa Rica are two and half times more likely to reach the age of 92 than people living in the United States or Europe."

Here are the three foods that form a staple to the Nicoya Peninsula diet and why you should consider implementing them into your own.

Nicoya Peninsula inhabitants make 'delicious whole grain tortillas' out of corn, according to Buettner.

The National Geographic Fellow also talked about the Nicoya inhabitants' traditional process of soaking corn kernels in wood ash in his Netflix docuseries Live to 100.

This process reportedly "boosts the nutritional value", Buettner claims.

Rich in fibre, you can still enjoy all the nutritional benefits of the corn without making it into a tortilla.


Rich in vitamins A, B, and C, as well as magnesium and potassium, squash is reportedly crucial for our bones, blood, and heart health, according to the Cleveland Clinic.

Squash is a straightforward vegetable that we can easily roast or add to a healthy and hearty stew or soup.


Finally, Dan notes that Nicoya inhabitants regularly add beans to their meals and apparently they enjoy up to five different varieties.

For instance, black beans are a prominent ingredient in a popular dish called gallo pinto.

The author also highlights that beans feature in many other Blue Zones like Ikaria in Greece and Sardinia in Italy.
