Hi Duane, There is no doubt that wheat as a carbohydrate (rice as well) as principal staples in much of the world’s diet, contribute to obesity. GM foods are closely studied throughout their development and it takes years for them to become commercially available. And the same rules apply for the procedure of cross breeding wheat and other crops using embryonic seeding. Is there a correlation between heightened metabolic diseases and the use of transgenic crops? Nothing in the scientific literature to date. And the only study that linked GM foods to tumors in mice was badly botched by those who conducted it, to the point that its validity has been seriously questioned by even the anti-GM scientists.
