Production

Similar method of production to ethanol

Enzymes that break corn syrup into pure fructose

System to convert glucose found in corn starch into fructose

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?

Rat Study
