Some other substances
Controversy

Production
Similar method of production to ethanol
Enzymes that break corn syrup into pure fructose

Obesity
What causes different monosaccharides and disaccharides to be better or worse for us?

Excess glucose in our bodies is converted into fat, which is why HFCS gets blamed for obesity
Is everyone getting fatter in general, or is it because of HFCS?
