For posting that link to the GMO/glyphosate piece .
I spend lengthy periods of time in Colombia . In the USA , I tend to have edema . Within a couple of days in Colombia and eating local foods , my edema disappears . On my return to USA , the edema reappears . Salt is NOT the culprit . I use the same brand of sea salt in the same quantities in both countries .
I suspect glyphosate residue in my food in the USA .
