Lustig is unfortunately a scientific crackpot. His lecture has many untruthful statements (like those about Japanese) and puts blame mostly on fructose.

As much as fructose does cause some interesting metabolic problems, unlike glucose, it still cannot be characterized as unhealthy (because the very Japanese he praises eat a lot of fructose and the studies are done on fructose extracts which can't even be reproduced with equivalent fruits in fructose amounts).

He makes equivalent claims to those made by Campbell in his China study that casein from milk causes cancer - of course it does if it's 20 freaking percent of your caloric intake (which is practically impossible to consume long-term).
