I'm not sure why he would say the unhealthiest population on earth ─ meaning Americans, when you have places like Swaziland, with a life expectancy of 32 years (vs. 78, according to the CIA).

Which of those countries would you say has a bigger health crisis?

The reason for a low life expectancy in Swaziland isn't that people eat unhealthy food, it's because they have no food to eat at all - 60% of the population get by on less than $1.25 a day. On top of that 38.8% of the population is HIV positive.

Americans have the choice of healthy living, Swaziz don't.

The underlying reasons for the gap in life expectancy are quite different, but my main gripe is with the author using the sensationalist, marketing claim that Americans are the unhealthiest people on earth, which seems to be a popular meme.

I don't disagree for a second that Americans as a population could be healthier, but that is a different, less you need to buy my book now kind of statement.
