This bit from the article is what caught my attention:
Fructose is not just another calorie. It acts as a metabolic signal that promotes fat production and storage in ways that differ fundamentally from glucose.” — Richard Johnson, MD, professor at the University of Colorado Anschutz and study lead author



Yep, that’s right. The conclusion that fruit is unhealthy because it contains fructose would be misleading, though.
