100 Million Years Of Food by Stephen Le

What Our Ancestors Ate and Why It Matters Today

Blending evolutionary biology, anthropology, and travelogue, this book explores how human diets have been shaped over millions of years and why traditional eating patterns often align with our biology. Visiting communities across the globe, it examines regional staples—meat, dairy, grains, legumes, spices, and fermented foods—and the genetic adaptations that influence how we digest them. It critiques one-size-fits-all fad diets and argues for context: eating largely unprocessed, culturally familiar foods, in moderation, with attention to lifestyle factors like activity and communal meals. The result is a practical framework for navigating modern food choices by looking to ancestral patterns without romanticizing the past.
