Don't waste your time on this book. It's basically support for business as usual and the current standard approach in cardiology, that at best slows progression of heart disease, but does little to stop its onward march -- let alone reverse it.

For example, when the author discusses artificial sweeteners - including aspartame, on the surface, she appears to be, "evidence based" in her discussion and gives the impression that this substance is probably ok for those who don't have PKU, since most studies suggest it does not cause harm. Had she looked a bit deeper, however, she might have considered that when you separate research on aspartame into two groups -- that sponsored by industry, and that sponsored by others -- the safe/not safe conclusions, pretty nearly split along the same lines! Caveat Emptor.

Similar, uncritical thinking and lack of awareness peppers almost everything in this book. If you really want sound science, rather than re-spouting of the widespread dogma that eventually leads its followers to drugs and surgery, these are much better books:

Just for fun -- here are links to a few studies that do suggest Aspartame is NOT so safe. I can't help but wonder if the author was unable to locate any of these studies when she wrote her book, or else had some reason to disregard them. But I had wondered that over and over as I read much of this book:
