Lots of people dont seem to like the title.
As someone with access to several medical journals I found it amusing. All the time I read papers that show the tested intervention prevented some specific outcome to a specific degree and also prevented just death in general to some specific degree. They'll be like 'this herb cured belly button fungus in 67% of patients, oh and it reduced death in general by 13%'.
I always found those bits inexplicably amusing so I got a laugh out of 'How not to die'.
I just finished reading the book. For those who cant afford it, just watch every video on nutritionfacts. They cover most of the more sciencey information in the book, the book just puts it into a much clearer order and format and includes useful tips and some practical food tips.
