What is it?

Advantages over sucrose

Sweeter

Cheaper

Easier to handle

55% Fructose 42% Glucose

More fructose than typical sucrose

How is fructose different?

Yields more ATP

Metabolizes in the liver

Some other substances

Controversy

Extreme prevalence in our diet makes it hard to get rid of

Correlation to obesity, heart disease, cancer

Frequently blamed for obesity

Included in almost all food products

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

Obesity

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

Different metabolization/enzymes used?

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
