Interesting! I was just commenting on this in a couple of other threads.

My issue isn't as much depression as it is anxiety, but they are related. And I can tell you that when I am low carbing I feel a significant reduction in my anxiety and I don't feel the doom and gloom kind of depression that I do when I am eating sugary,starchy foods. Also, I started taking extra magnesium and D3 about three weeks ago and the difference has been noticeable as far as my ability to handle things that are stressful or would typically launch me into an anxious or depressive reaction.

The potatoes not prozac thing is very interesting to me. I had not heard of it before! Thanks for pointing it out pmezak.
