Dan Buettner quotes:

While working in the “Blue Zones” areas, I found that having a strong sense of purpose, a circle of healthy friends and living in walkable neighborhoods are all as important as a good diet. But I also realized that food is the entrance ramp for better living. So, I started this book by distilling all of the diets of longest-lived people into one über diet of sorts.

…But I can tell you that the longest-lived are getting 95% of their calories from plants and only 5% from animal products.

No matter where you go, the snack of choice is nuts.  People who eat nuts live 2-3 years longer than non-nut eaters.  But remember, they are moving all the time, not sitting at desks, in cars or watching TV.
