Query: the best advice!

I've ordered this book before--I lend it out and replace it again and again. My friends always keep their copies because they have the same experience I have (and they want to keep the recipes on hand). Using its advice, I've successfully lowered my cholesterol dramatically without the dangerous drugs that are prescribed everywhere today. It's realistic, easy-to-read, and helpful.
