Understanding why the body breaks down — and what it needs to restore itself.

---

John Bagnulo works at the intersection of nutrition science and cellular biology to answer a question that conventional medicine rarely asks: why does the body break down — and what does it need to heal?

His work is rooted in the understanding that most chronic disease is not the result of genetic fate or inevitable aging, but of biological conditions that can be identified, understood, and corrected. Through decades of clinical research and teaching, John translates the complex machinery of inflammation, oxidative stress, and metabolic function into clear, actionable knowledge — giving people the tools to participate meaningfully in their own healing.

As a naturalist, John brings a dimension that sets him apart from other nutrition scientists: a lived, embodied understanding of food as ecology. His work traces the roots of health from the soil to the cell, from ancestral foodways to modern biochemistry — making him one of the most compelling and genuinely original voices in integrative nutrition.
