I've tried to read this book twice now, and bar the only chapter which seemed to have any evidence, or indeed anything remotely interesting to say (Dr. Malcolm Kendrick's views on cholesterol) the rest of the book conflicts with 'psuedoscience' and strict interpretation of epidemiology; then uses the very same to make its point.
After around 100 pages of reading, as another buyer has suggested, 'thinly veiled right-wing rants', and several instances of "we're medical doctors... so trust us, WE alone know what is good for you," I gave up, on both occasions.
I certainly wouldn't purchase any more titles by the authors.
