Sugar: The Bitter Truth

In his lecture, available on YouTube, Robert H. Lustig, MD, UCSF Professor of Pediatrics in the Division of Endocrinology, explores the damage caused by sugary foods. He argues that fructose (too much) and fiber (not enough) appear to be cornerstones of the obesity epidemic through their effects on insulin. 
"Dr. Lustig is a nationally-recognized authority in the field of neuroendocrinology, with a specific emphasis on the regulation of energy balance by the central nervous system. He is currently investigating the contribution of biochemical, neural, hormonal, and genetic influences in the expression of the current obesity epidemic both in children and adults. "
