Know what else has HFCS that you would never even guess? Maple syrup! Yes, most of the popular brands of maple syrup such as Aunt Jamima is not actually real maple syrup. I imagine if you look hard enough you'll find the real stuff, but most people just buy what's in front of them and what they've known and grew up with, and assume the product actually is what it says. WRONG! Check the ingredients. Check the ingredients on peanut butter too. It's not just peanuts. If, there even is peanuts.
Lot of companies use very sneaky tactics to mislead the consumer, without actually lying, and still follow all the regulations such as listing the ingredients. The food industry is not about feeding us, it's about making money, without getting sued, so they still have to put some effort towards making food actually safe, but not more than that. If it taste good, we keep buying it, does not really matter what's in it.
