His company - "Blue Zones" - specializes in educating people about health and well-being based on global science, social science and psychological research.
He claims diet has a huge impact on the longevity on someone's life.
"We found five parts of the world where people are reaching age 100 at higher rates than anywhere else [and] they eat a plant-based diet, but that doesn't mean you can't eat meat. They eat meat about five times per month," Buettner said.
They also eat a lot of beans and nuts. People who eat a handful of nuts at least four times a week live two to three years longer than people who don't eat nuts.
Boettner also talked about how short naps can have a positive effect on your life.
"We know that just sleeping a half hour just five times a month is associated with about a third less heart disease, which of course [leads to] more longevity," Buettner said.
He has a new book scheduled to release in early November.
The name of the book is "Blue Zones: 9 Power Lessons for Living Longer from the People Who've Lived the Longest."
Buettner will also be discussing lessons and tips during a Northwestern Mutual-Denver sponsored event on Thursday from 5:30 to 7:30 p.m.
