Using ground-breaking work by medical researchers in the areas of natural and processed foods, bestselling author John McKenna analyses the diet of a typical child in the modern developed world, showing both the nutrient and the toxic content of their diet. He explains why diseases such as diabetes, obesity, heart disease and cancer are on the increase, and explains why food intolerances are increasing at a phenomenal rate.

He sets out the cornerstones for healthy eating, giving examples of nutrient-rich diets and explaining precisely how they make a difference. He also surveys the recent history of food processing and looks at the simple ways we can go about reducing our intake of harmful toxins.
