Query: Health or grammar?

If we want to read a book in perfect grammar and punctuation, we could read countless English and grammar books. Mrs. Cox's book is easily followed, easy to remember when shopping for my family, and just plain common sense nutrition. Since most of us have heard the rhetoric time and time again and still don't follow what "science" tells us to do anyway, it is refreshing to have a one on one coversation with her in this book. The entire time I was reading, I felt as if she was just having a simple, encouraging converation with me. Her book works! (oops another exclamation point). I have put these suggestions to task, and have lost over 30 pounds, without going on a "fad diet" which no one can survive on forever. Success wins in my book!
