I have bought a number of "Guides for Dummies" on a wide variety of topics not to do with health, and this was up to the very high standard of all others.It is a very helpful and informative first book for those diagnosed with Raised Blood glucose levels; there is a section devoted to recipes which I have tried and my family have enjoyed, even those who do not have my condition. The only adverse comment is the size of the meals - for much larger numbers of people so they have to be scaled down. Some can be divided up and frozen in suitable sizes, but not all.
