Interestingly, I just had this land in my FB feed:
Granted, it was posted by Occupy Monsanto, but what interests me is the possibility that "glyphosate enhances the damaging effects of …food borne chemical residues and environmental toxins. Negative impact on the body is insidious and manifests slowly over time as inflammation damages cellular systems throughout the body. Here, we show how interference with CYP enzymes acts synergistically with disruption of the biosynthesis of aromatic amino acids by gut bacteria, as well as impairment in serum sulfate transport. Consequences are most of the diseases and conditions associated with a Western diet, which include gastrointestinal disorders, obesity, diabetes, heart disease, depression, autism, infertility, cancer and Alzheimer’s disease.”
I've done lots of market research for manufacturers of obesity drugs, and I've always been suspicious that the explosion of obesity in this country (see this astounding CDC obesity trend deck) is something "under cover": not just people eating more McDonalds, but something much more insidious, like HFCS or some endocrine disrupter.
