In this issue...September 2014

Dear Readers,

Welcome to the September 2014 True North Tune-Up. We continue to emphasize "up stream" strategies for health in the areas of nutrition, mind-body, and lifestyle. Studies are from peer-reviewed scientific journals. (There are now 300 or so predatory journals among the many good free journals on line, where low quality studies are published in return for money payments!) Archived prior issues of the Tune-Up may be found here.

To your health,
B. Joseph Semmes, MD
Director of Research, True North
Diplomate, American Boards of Internal Medicine and Emergency Medicine, Hospice and Palliative Medicine
