“If you’re eating something that came wrapped in plastic and contains even one ingredient that wouldn’t be found in most household kitchens, it is most likely ultra-processed food,” writes today’s guest, Dr. Chris van Tulleken (pictured above). His latest book, an international bestseller, is Ultra-Processed People. He says that North Americans get 50-60% of their calories from ultra-processed food. So how is ultra-processed food affecting our bodies and our brains? How is it really bad for us, and how can you optimize your wellness in an ultra-processed world? Medcan director of food and nutrition Leslie Beck, RD, answers these questions and more in her conversation with Dr. Chris van Tulleken.
