Query: Excellent book for anyone who wants the truth about the food industry

My sister has been diagnosed with severe osteoporosis, and in the first chapter I found this to be one of the results of her years of living on meat. It opened up my eyes, and I am SO glad I bought this book. Recommended to anyone who wants to learn the truth about the foods we eat every day and start eating for a healthier life.
