The world of diet advice is crowded with bold claims, conflicting headlines, and passionate opinions. Paleo or vegan? Low-carb or high-carb? Supplements or whole foods?
In Search of the Optimal Human Diet takes readers beyond trends and into the science itself. This comprehensive yet accessible guide traces the history of nutritional science—from early experimental discoveries in the eighteenth century to modern, technology-driven metabolic research. Along the way, readers gain insight into how scientists developed the tools and methodologies that allow us to understand how the body metabolizes nutrients.
Rather than promoting a fad or quick fix, this book equips readers with the foundational knowledge needed to evaluate dietary claims critically. By understanding how nutritional science evolved—and where it stands today—readers can cut through confusion and make evidence-based decisions aligned with long-term health.
Designed for curious laypeople who want clarity without oversimplification, this book offers the context, history, and scientific grounding necessary to approach diet and nutrition with confidence.

Unlike the creation story in the Old Testament that attributes the human fall from grace to the first man Adam eating an apple from the tree of knowledge, this book based on science and history contends that our downfall began with the introduction of meat into the human diet.
The human body is perfectly adapted to thrive on a diet of fruits, vegetables, tubers, nuts, and seeds, and is ill-equipped to metabolize a diet rich in meat, dairy, and eggs. This mismatch between our adopted diet and our evolved physiology has not only unleashed an epidemic of chronic degenerative diseases upon humanity, it is also a leading cause of global warming and mass species extinction here in the 21st century.
Man Eating Plants weaves together published works by the world’s leading scientists and historians to narrate how we arrived at these three interrelated crises and how transitioning back to our original plant-based diet could be our saving grace.
