Yeah, brand name Round Up is way too expensive. Today's commercial farmers use non-branded versions of Glyphosate.
It's applied to grain crops days before harvest as an incentive for the plants to put their last bit of energy into increasing the size of the grains - especially soybean and wheat crops. And it's been standard practice for quite a number of years now.
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.
