Columbia has a one year MS in Human Nutrition, where physicians, those planning on going into medical school, and those considering a phd in Nutrition study the clinical and molecular aspects of nutrition with respect to disease and health.
It is ok (I'm doing it). I thought it would be a lot more clinically oriented, considering it is in P&S, but most of the courses focus on molecular aspects and nutritional research. I probably wouldn't do it if I had to do it over again, but I guess a MS from Columbia can't hurt the resume. Actually, if you are interested in the pathophysiology of obesity, syndrome X, etc it is a very informative program. The weakness lies in its organization and the wide range lecturers (some are great, some suck).
You can find the program by going to <a href="http://www.columbia.edu." target="_blank">www.columbia.edu.</a> then click on Departments, scroll down to P&S and click on the Institute of Human Nutrition.
