PlantPure Nation. Dir. Nelson Campbell, 2015. Three people try to start a pilot program to document the health benefits of a plant-based diet. “PlantPure Nation presents a compelling case and offers a simple solution to pervasive health conditions such as heart disease, diabetes, and obesity. This film is part of a grassroots movement that will hopefully inspire people to make healthier, scientifically based decisions about how they fuel their bodies” (Ira Israel, Huffpost).
