📖 Overview
Steven R. Gundry is a cardiothoracic surgeon turned nutrition researcher and author who developed theories about lectins and their impact on human health. He founded the International Heart and Lung Institute and later shifted his focus to preventive medicine through dietary interventions.
Gundry gained attention for his claims that lectins—proteins found in many plants including grains, legumes, and nightshade vegetables—cause inflammation and contribute to autoimmune diseases, weight gain, and other health problems. His approach centers on eliminating lectin-containing foods from the diet.
He has written several books promoting his lectin-avoidance protocol, starting with "The Plant Paradox" in 2017. His subsequent works include cookbooks and expanded theories about energy metabolism and gut health.
Gundry operates medical practices in California and sells nutritional supplements. His theories have generated controversy within the medical and nutrition communities, with critics questioning the scientific basis for his broad claims about lectins and plant foods.
