In this book, Chris van Tulleken marshals the latest evidence to show how governments, scientists, and doctors have allowed transnational food companies to create a pandemic of diet-related disease. He undertakes a self-experiment, eating a diet of 80 percent ultra-processed food for a month, under the supervision of colleagues at University College London. The book explores the origins, science, and economics of ultra-processed foods, revealing their catastrophic impact on our bodies and the planet. Van Tulleken proposes real solutions for doctors, policymakers, and consumers, emphasizing the need for global action to address the issue.

In 'In Defense of Food', Michael Pollan argues that the Western diet, characterized by highly processed foods and a focus on individual nutrients, has led to increased rates of chronic diseases such as obesity, diabetes, and heart disease. He proposes a simple yet profound alternative: 'Eat food. Not too much. Mostly plants. ' This approach emphasizes the importance of whole, unprocessed foods, moderate portions, and a diet rich in plant-based foods. Pollan critiques the food industry and nutritional science for creating confusion about what constitutes healthy eating and advocates for a return to traditional, culturally informed ways of eating.

This book delves into the purpose and power of sleep, explaining how it affects every aspect of our physical and mental well-being.

He also explores the consequences of sleep deprivation and provides actionable steps to improve sleep quality, including ways to prevent cancer, Alzheimer’s, and diabetes, slow the effects of aging, and increase longevity.
