In his new book, "Health Food Junkies," Dr. Steven Bratman says he sees evidence of unhealthy fanaticism about diets--from The Zone, to macrobiotic. He talks with Laura about how to recognize when your self-imposed food regimen is hurting your social life, and possibly your physical health. Steven Bratman, M.D. is the medical director of Prima Health, an alternative medicine publishing company, www.primahealth.com.
