Darden North, MD, contributes to the "Fat Kat" blog about nutrition and also works in a little promo about his novel writing.

Although I have been happy to sign a book for one of my much appreciated ob/gyn patients, my policy has been to keep my medical practice and writing novels separate. While my novels are mysteries and medical thrillers, I do not render professional medical treatment or address personal medical concerns through my author's website or my Facebook listing. (I use Facebook as a combined fan and personal venue.) However, Melanie Calvert Benton recently asked me to contribute an article about nutrition to her blog Fat Kat. Since I was able to work in a little book promotion into the piece (cleverly, I hope), I decided to share it here as an example of taking the opportunity to slide in a bit of free book marketing.
