His introduction is devoted to explaining the different types of scientific studies. This is helpful and made me appreciate the many hours he must have spent sorting through reams of research of variable quality to come up with conclusions that are supportable. Each chapter examines the research surrounding a particular food type. He covers, butter/animal fats, meat, eggs, salt, gluten, GMO's, alcohol, caffeine, diet soda, MSG, and organic foods. Unfortunately, sugar is left out, except by inference in comparison to artificial sweeteners. Well written, well explained, with practical advice.
I have and will cite and quote this book! It dispels many food 'myths' and clarifies good eating habits without fads and confusing advice. Eat! Eat right! Be mindful and balanced and don't overdo anything.
