This book explores the alarming rise of ultra-processed foods in our modern diets and their detrimental impact on physical and mental health. We delve into the differences between processed and ultra-processed foods, examine the dangers of refined carbohydrates, and uncover the link between insulin resistance, diabetes and cognitive decline, including Alzheimer's disease, and mental health conditions like depression and anxiety - now common in children and teenagers. By understanding the science behind these dietary choices, we can empower ourselves to make informed decisions for a healthier future for ourselves and our families.
