do that many people really use veganism as a health diet? i’m sure some do, but it seems weird to be on the list, unless i’ve just missed something. i’m a vegan, and i know a lot of people who are, and none of us do it for health reasons.

As a long term Type II diabetic, I can tell you Atkins was/is right!

The Blue Zone idea has been around a long time--it just didn't have a snappy buzzword. Because of my past time spent in Mediterranean countries, I've been doing / eating / living all the same ideas for over half my life. I'm glad that Natl Geo did the Blue Zones project because it helps many other people catch on to the idea. I'm old as dirt, and I'm healthier than most people 10 to 15 years my junior.

The trouble with all these diets is they are often a short time thing used to lose weight. Afterward the person goes right back to the same old bad habits. Health means adopting a lifestyle that promotes health and sticking to it.
