Food Is Medicine

A world-renowned cardiologist and expert in nutrition offers a blueprint for a nutrition revolution to mend our health, economy and planet

Food should nourish us, but instead it’s making us sick: from obesity and diabetes to heart disease, cancer, and poor mental health. As cardiologist and public health expert Dariush Mozaffarian shows, the problem isn’t how much we eat – it’s what we eat too little of: the foods that heal, protect and restore the body and mind.

Cutting through widespread confusion and misinformation, he reveals astonishing new discoveries about how food truly affects our health, our biology, and even our longevity. Harnessing the power of the right foods, he shows, can do more than prevent illness; it can treat disease, extend life, and reduce the staggering human and economic costs of ill health. Food Is Medicine maps the path forward, from transforming our own diets to reshaping what grows on our farms and reaches our stores and our plates.

Uniquely positioned on the frontlines of nutrition, medicine and public policy, Dariush Mozaffarian draws on cutting-edge research to turn complex science into a clear, actionable plan for reversing today’s health crisis. He reveals the medicinal power of ideal nutrition, breaks down widely accepted myths and false narratives driving modern choices, and introduces the innovators who are pioneering breakthrough solutions – in doctors’ offices, supermarkets, communities, and the halls of power.

Braiding storytelling, science, and practical wisdom with clarity and optimism, Food Is Medicine offers a bold new vision for a food system that can help each of us to live a longer, healthier life.
