Well produced documentary which backs up other research such as active healthy life style, social belonging and community along with the importance of keeping stress levels low.
However nutritionally it's false- the guy pushes his own Vegan and vegetarian agenda, massively over emphasising that diet, claiming all the blue zones are primarily vegan/vegetarian!! The only one this is true for is the evangelical church community in America- ALL the others have meat and dairy in healthy portions as part of a well balanced diet. They do consume a lot of good healthy foods but overall less calories!
Meat and diary are not evil and not eating them will not guarantee you live longer.
Otherwise a good and interesting documentary- basically shaming the modern western world we live in that is stressful, lazy and lonely - it's those things that are killing us early.
