No, I haven't watched the video, but I've read several of his articles like the one that started this thread (I tend to prefer to read content than watch a video of someone speaking it; quicker to read, less disruptive of people around me, easier to quote, easier to refer back to later to make sure I got his point right, etc; if you have reference to a written description of the same content I'd take a look). Calling fructose a "poison" or "toxin" is excessive. It twists the conventional meaning of those words.

I definitely agree that people are eating too much fructose, and too much sugar in general, and that it has been driven by several government interventions (fat-free diet advice, corn subsidies, etc). I just object to calling it a "toxin" or "poison", and find his single minded obsession with fructose to be a bit of a poor way to attack the problem in the same way that single minded obsessions with "fat free" or "no carb" were. Human diet is a complex topic, with a lot of interacting factors, and over-simplifying advice can be quite harmful.
