I think this book should be a must read for... everyone! This book will really make you stop and think about what foods you choose you put into your body. The basic idea of the book is that real, natural foods are best for us- and, yes, she backs up her claims with historical and nutritional facts. Real foods (even ones we have been brainwashed to believe are bad for us like real butter, real cheeses, and traditionally grass-fed beef) are what we should be eating because that is the way nature intended. The chemicals and pesticides are foods are now grown and produced to include are what is making us unhealthy and overweight. I know it sounds cheesy, but this book has really changed my family's life and the way we choose what food we eat. I love knowing I am feeding my family healthy foods that are not filled with chemicals- read this book!
