In order to patent a natural plant, Coca Cola and Cargill would have to modify the plant, most likely genetically to produce something "new". Interestingly, the FDA would not allow producers of stevia to call it a sweetener, because of the food industry lobby who did not want competition from a sugar "substitute" that was all natural in origin. Those companies selling stevia were forced to market it as a dietary supplement. I did notice recently that SweetLeaf (Wisdom in Gilbert, AZ, see
www.sweetleaf.com) had changed their packaging to show a packet of stevia being poured into a cup of coffee or tea, hinting at what it is actually used for. Since Coca Cola is not a food, but rather a concoction of chemicals and sugars that started out as a medical remedy that contained cocaine, then was regulated by the newly-found FDA because of its addictive properties, anything new they do to it will not redeem it. Unfortunately, our government agency founded to protect us from foods and medicines that were bad for us, is owned lock, stock and barrel by the Corporations and will continue to approve unhealthy and dangerous products based on bogus research funded by those same corporations. My only hope is that Cargill will not try to force out natural stevia once they have their modified form of it.
