Lustig's position is tenuous at best, and at times he either carelessly misleads people or outright fabricates points to support his little crusade. Here's (http://sweetenerstudies.com/sites/default/files/resources/fi...) a take-down of a number of issues, logical and factual, in his recent book, and here (http://www.alanaragonblog.com/2010/01/29/the-bitter-truth-ab...) is a critique of his underlying argument about the unique threat posed by fructose (plus some follow-up based on comments and Lustig's own response to that piece http://www.alanaragonblog.com/2010/02/19/a-retrospective-of-...). Basically, even where Lustig is correct his points don't reflect any real-world situations.
