Among all developed countries, Americans are the fattest people in the world. The World Health Organization found over 60% of the American population is obese or overweight. Even more disturbing, the U.S. is the only country in the developed world to label obesity a national security health risk. Top Pentagon officials have warned Americans are becoming so fat, most of those volunteering for the Army are disqualified because of their size. Child obesity is also on the rise in the U.S. The Centers for Disease Control estimates 1 in every 3 American kids are either obese or overweight. Jeffrey Smith, the author of Seeds of Deception, points to the mass production and consumption of genetically modified foods in the U.S. as a possible source of the problem.
