T. Colin Campbell, Ph.D., bestselling author of The China Study, and his son, Nelson Campbell, are conducting a nationwide bus tour to preview the opening of the feature-length documentary PlantPure Nation. Beginning in April, they are visiting 23 cities, and will be in Tampa-St. Petersburg on Sunday, April 12 to screen and discuss the film, which examines the political and economic factors that suppress information about the benefits of plant-based nutrition, including its positive impacts on medicine, farming and food deserts.

Events will include book signings of The PlantPure Nation Cookbook by Kim Campbell, Nelson’s wife; filmed meet-and-greet rallies and fan interactions that may appear in the final release; community engagement to celebrate the benefits of a plant-based diet; and recruitment of ambassadors in each city to help build local interest in viewing the official release of the film, which is planned for the week of July 4 in the tour cities, with subsequent rollout throughout the country.

PlantPure Nation—directed by Nelson with producer John Corry and writer/director Lee Fulkerson, who also teamed up on the acclaimed documentary Forks Over Knives, features the perspectives of Colin and other world-renowned experts, doctors and authors.
