Mercury in HFCS (High Fructose Corn Syrup)
"Two recent studies that found mercury in HFCS and in foods containing HFCS suggest that the sweetener could be more of a threat to health than previously believed. HFCS is used in almost all soft drinks and a great many processed foods, ranging from salad dressings and ketchup, to jams, jellies, ice cream, and many others - even bread. HFCS contains a high percentage of fructose, much more than regular corn syrup. I've long been concerned that it has disruptive effects on metabolism, because the body doesn't utilize fructose well, and humans have never before consumed it in such quantity. I believe it is a major culprit in the obesity epidemic, especially in kids.
"You can lower your mercury levels over time by simply not eating fish likely to contain it; opt for wild Alaskan salmon, sardines, herring and black cod instead. It may take months for blood levels to drop. I've long recommended avoiding foods containing HFCS for other reasons. The mercury issue makes the case against this sweetener more compelling."
