A table of context gives the page numbers for each entry. However, it is hard to find items by flipping though the pages as the publisher did not put identifying markers at the top of each page, like the item or letter covered on the page. So one has to keep turning pages to where the next entry begins to find out where in the alphabet you are. And flipping back and forth to the table of contents is tedious. But these format problems aside, the information presented is rather good.
Cooper provides sound recommendations on each of the items.
And the scientific research given enables the reader to decide for yourself if Cooper's recommendations are correct. In fact, this research is so helpful that I cite some of it in my book Creationist Diet . I also have referred back to Cooper's book many times for personal information. For instance, I have multiple allergies. But I am glad I read Cooper's entry on licorice before trying it.
