True, but that doesn't eliminate the possibility that the author may still be an idiot. I doubt that any Glyphosate which may be deposited on the soybean PODS and wheat HUSKS in the last days before harvest is the cause of any significant health risks. Those are discarded in the harvesting process.
Since antibiotic use has been shown to be linked to development of celiac disease, I'd bet that the healthcare industry is a bigger factor in causing health problems than the agriculture industry is.
That said though, I still try to maximize my food intake from my own organic vegetable garden and fruit trees and bushes. I get a lot more nutrition per calorie that way.
If the roundup was not absorbed into the plant it would not stimulate growth. So its pretty clear that discarding the husk does not remove the glyphosate.
