Fructose. Finally, we come to the Voldemort of the dietary hitlist: the sweet molecule in sugar. If it’s sweet, and it’s caloric, it’s fructose. Period. This is the one foodstuff whose consumption has increased worldwide, and with reckless abandon. And it is the one that children eat with no holds barred. We have animal and human data. We also have the golden ticket: correlation *and* causation. Every age group, including infants, has increased its consumption of fructose in the last thirty years. As far as I am concerned, this is where the action is.
