Did you know that there are deliberate campaigns designed to confuse us about the risks of tobacco, the ozone hole, pesticides, GMOs and climate change? Join Food Sleuth Radio host and Registered Dietitian, Melinda Hemmelgarn, for her interview with Naomi Oreskes, Ph.D., co-author, of Merchants of Doubt: How a Handful of Scientists Obscured the Truth about Tobacco Smoke to Global Warming, the book that inspired the film of the same name. Food Sleuth Radio helps listeners "think beyond their plates," connect the dots between food, health and agriculture, and find food truth.
