The quality and accessibility of food has been a hot button issue throughout the ages. Lack of secure food has been the source of revolutions and toppled governments. In "Food Fight," we look at the tug of war over America's diet. From questions plaguing genetically-modified ingredients to wheat-free/gluten-free concerns to the rapid decline of bees, we explore pressures on the safety and security of our food supply. Rich Food, Poor Food authors, Jayson and Mira Calton, guide us through a grocery store and reveal how to make smart choices and avoid unwanted ingredients. Cardiologist Dr. William Davis, author of Wheat Belly, tells us his surprising results after removing wheat from his patients' diets. Filmmaker and concerned father Jeremy Siefert tells his journey trying to understand the impact of genetically-modified food on his children's health. Bee experts sound the alarm about the decline of our most valuable pollinators and what we can do to make sure they continue supplying us with fresh fruits and vegetables.
