Again, this is not just some blind data cherry-pick, "zucchini-eaters live longer". Robert Lustig has written and spoked extensively about his hypothesis for why fructose is toxic for the human liver and metabolism[1]. It's a controversial idea, but IMO he has made a compelling argument and is now gathering data which supports the hypothesis.

If you want to argue against the hypothesis, please do.
