Corn Syrup or High Fructose Corn Sugar (HFCS) has a lot of uses. Just look for it in about all of the prepared foods you buy from cakes to ketchup. Yes it is used in homebrewing for carbonation ( and personal exprience tells me it works well) and it can be used for about anything cane sugar can.
There is a line of thinking, and I believe it has some merit, that HFCS is the cause of childhood obesity in many American children as it is found in so many ready to eat prepared foods and in soda pop, even diet. Those couple of carbon atoms cause it to be metabolized in the liver and as such can lead to cirhossis and juvenile diabetes in adults. It has a long shelf life and is a favorite of corn growers everywhere. While I am not a doctor I would urge caution in its use. Anybody else have any other opinions? I would like to hear them.
