I've been reading a lot about a recent study that highlights the presence of mercury in high fructose corn syrup (HFCS). The Institute for Agriculture and Trade Policy issued a report called "Not So Sweet: Missing Mercury and High Fructose Corn Syrup." The report finds that some HFCS is made with mercury-grade caustic soda. It's an outdated technology, yet HFCS manufacturers still appear to be using it, and the mercury is making its way into a variety of food products on store shelves — nearly one in three of the 55 HFCS-containing food products that the study tested. These were things like snack bars, barbecue sauce, sloppy joe mix, yogurt and chocolate syrup. Many of these food products are marketed to children and have HFCS as the first or second ingredient on the label.
I think there are a lot of reasons to avoid HFCS (if you haven't already, watch the movie King Corn), and this is just yet another reason to read labels carefully.
