John Bagnulo, MPH, PhD, is a nutritional scientist, associate professor, naturalist, and farmer whose work is rooted in a simple but radical premise: that the answers to our most pressing health questions are not found in a pharmacy, but in our relationship with food, land, and the living world around us.
For more than two decades, John has worked at the intersection of nutritional biochemistry and human ecology — teaching at universities, leading programs at wellness centers across the country, and helping hundreds of patients reverse chronic disease through the power of whole foods. He has served as an associate professor and faculty member at multiple institutions and non-profit organizations, teaching courses on Human Metabolism, Brain, Heart, and Gut Health, Reversing Chronic disease, and the art and science of cooking.
John holds a Masters of Public Health from the University of North Carolina and a Doctorate from the University of Maine. But his education extends well beyond the academy. As a farmer and forager, he has spent years in direct relationship with the land — an experience that shapes his understanding of nutrition not as a set of isolated nutrients, but as a conversation between the human body and its ecological context.
His lectures are known for their remarkable range and depth. John moves fluidly between cellular biology and food culture, between ancestral eating patterns and cutting-edge research on inflammation, oxidative stress, and mitochondrial health. He places food at the center of a web that stretches from the soil to the cell, from our ancestors’ kitchens to our own — illuminating how what we eat either sustains or disrupts the body’s extraordinary capacity to heal.
One of the foremost experts on food and health in the United States, John brings rigorous science, deep ecological literacy, and genuine warmth to every room he enters. His talks consistently enlighten and engage even the most well-read audiences — offering not just information, but a genuinely new way of seeing the relationship between human health and the natural world.
