In Dr. Steven Gundry's breakout bestseller listeners learned the surprising truth about foods that have long been regarded as healthy. Lectins, a type of protein found in fruits, vegetables, legumes, dairy, and grains, wreak havoc on the gut, creating systemic inflammation and laying the groundwork for disease and weight gain. Avoiding lectins offers incredible health benefits but requires a significant lifestyle change, one that, for many people, can feel overwhelming. Dr. Gundry makes it simpler than ever to go lectin free. His 30-day challenge offers incentives, support, and results along with a toolkit for success.
