Foods to Fight Cancer provides important information, but I advise you not to buy it. Far better, and definitely worth you money, is Anticancer--A New Way of Life.
FtFC is evidently a well-meaning but unsophisticated effort by laboratory researchers to write a book for popular consumption.
A book of fewer than 200 pages, FtFC has nearly 30 full-page color illustrations presenting virtually no useful information. For example, page 168 shows an attractive Asian child eating an orange, with a small caption recommending whole foods as superior to supplements. Almost ten more such pages include only a little information. For example, page 155 presents an "artistic" photo of a glass of wine along with four superimposed sentences.
Much space in the central eleven chapters recommending specific foods is taken up with historical and literary irrelevancies. For example, the discussion of green tea includes, among other things, a brief discussion of the Boston Tea Party, and a longer account of supposed historical reasons why Americans presently prefer black tea to green tea. At the other extreme, a fair amount of technical information is presented that is of no obvious use. For example, page 112 uses most of a page to present the chemical names and structural formulas for the principal polyphenols in green tea.
End-of-chapter summaries are a good idea, but in FtFC they are constrained by a Procrustean hexagon background so that all summaries are of about the same dimension no matter how much information might usefully have been included in a particular summary.
With irrelevancies removed and some careful editing, my guess is that the useful content of FtFC could be presented in a pamphlet of less than thirty pages.
The specific foods discussed are:
* Cabbage, and cruciferous vegetables generally
* Garlic, onions, and allium family vegetables generally
* Soybeans and certain soy foods (but not soy supplements)
* Turmeric, a spice, always with a small amount of black pepper
* Green tea
* Berries (strawberries, blueberries, blackberries, etc)
* Omega-3 fats (fatty fish like sardines, salmon, mackerel; flaxseed)
* Tomatoes
* Citrus fruit
* Red wine
* Dark chocolate
I found some useful pointers in the haystack, enough to cover the back and front of an ordinary postal envelope, and a couple tables of useful standard information (pages 73 and 123). There is also occasionally some MISinformation, as when, on page 97, the authors recommend eating raw soybeans, something you definitely do not want to do.
The authors of FtFC did humanity a great service by uncovering much precious information about foods that fight cancer. It took considerable professional courage even to undertake the pioneering effort. They also deserve praise for seeking to convey their findings past the stolid inertia of the medical world directly to the public. But they are better researchers than they are popular authors. The book you want is Anticancer--A New Way of Life; it provides a great deal more useful information. Be aware, though, that although Anticancer was first published only in 2007, there is already an updated 2009 edition.
