Something changed in the American diet back in the 1970’s and early 80’s. I think it was the introduction of High Fructose Corn Syrup (HFCS). We now have an obesity epidemic and most likely a type II diabetes epidemic as well. The link with HFCS probably cannot be shown directly but I suspect it is a major factor. Although the hazards of smoking tobacco were well known and documented for decades the tobacco companies fought for decades with fear, uncertainty, and doubt. I’m sure that ADM and Cargill will be at the forefront of denying that corn may be a factor if not the culprit.
