As for my "confounded analysis", the Eastern American Indians raised corn (with a higher protein content than today's verities), squash, beans, and harvested natural tubers (cat tail roots, arrow root), high protein cat tail pollen, and other plant based wild edibles including grains. They ate very lean red meat and consumed fish, acorns and other wild nuts. Their diet was low in fat, sugars. In other words, their diet was, more or less, the recommend "food pyramid". Nevertheless, they did not live into to their 90's and 100's. Therefore, the article being mostly bunk, its author, and its supporters are suspect as to their motives. If you were against Universal Health Care, why not just say so.
