approach

Julia’s approach to journalism is rigorous, analytical, and deeply evidence-driven. Her work resists hype, foregrounds uncertainty, and situates health issues within the broader social, political, and structural forces that shape them. 

Nutrition isn’t rocket science; it’s harder.

Food Intelligence

In Food Intelligence, Julia Belluz and leading metabolism scientist Kevin Hall dismantle diet myths and bring clarity to one of the most confusing topics of our time: what to eat, and why.

Drawing on decades of research, the book explains how protein, fat, carbohydrates, vitamins, and metabolism actually work — and why many popular narratives about food collapse under scrutiny. It also examines how modern food systems turned eating—something humans have done forever—into a cognitively and emotionally demanding task.

The book’s central insight is both sobering and liberating: our struggle with food is not a personal failure of willpower, but the predictable result of a distorted food environment.

    The essential guide for understanding what you’re eating, and the forces that are driving you to eat it.

    **AN ECONOMIST BOOK OF THE YEAR**


    Nutrition isn’t rocket science; it’s harder.

    There are new diet fads, bold claims about superfoods and articles promising the secrets to lasting weight-loss and longevity. The more ‘expert’ advice we hear about diet, the less clarity we have about what to eat.

    In Food Intelligence, award-winning health journalist, Julia Belluz, and internationally renowned nutrition and metabolism scientist, Kevin Hall, cut through the myths about nutrition to deliver a comprehensive book on food, diet, metabolism and healthy eating.

    Breaking food down into its constituent parts, Food Intelligence reveals:

    • The real science behind how protein, fat, carbs and vitamins impact our bodies

    • The wonders of metabolism

    • The latest ‘theories’ about blood sugar trackers and ultra-processed foods

    • How our food environment shapes our eating behaviors and the food choices we make every day

    • How diseases like obesity and type 2 diabetes are not a result of a failure of will power; they are consequences of food systems working as designed

    Humane and deeply reported, this journey into the science of food will equip you with the food intelligence you need to better understand what’s on your dinner plate, how it got there, and why you eat it.

Praise for Food Intelligence
