Query: A Disappointment

What a disappointment! Boosting Immunity is a collection of chapters by different authors that is poorly focused and lacks continuity. There is nothing new in this book. It is mostly a rehash of commonly available information and some of the chapters, like chapter two, read like they were copied out of an enclyclopedia. The most attractive thing about this book is the title. Save your money.
