"Your Guide to Lowering Your Blood Pressure with Dash Eating Plan" was one of the required readings for University of Pittsburgh's "Nutrition and Physical Activity for Health" coursera course. I highly recommend that it be read alongside the short book "Dietary guidelines for Americans 2010", which offers some statistics and fills in numerous gaps in. Incidentally, it is a newer version of the book mentioned in the book I am currently reviewing, which was the 2005 version.
"Your Guide to Lowering Your Blood Pressure with Dash Eating Plan" offers a guide to amending one's habits for a sustainable change to overall health. Though it offers some guide to understanding labels on groceries and a few recipes towards the back, it does tend to repeat the same information over and over again. It is this same repetition that has led me to lower my rating from a 4 to a 3.
