Iron and Blood Glucose Levels

Dr Mercola has an interesting article out on the importance of proper iron levels in one’s blood. I think this is the one essential mineral that almost everyone knows about from school. According to the article, high-levels of iron are linked to heart disease, aging, mitochondrial disfunction and poor glycaemic control.

This made reminded me of Bill Sardi’s articles from years ago which was along similar lines. Sardi also made the case that one of the best ways to control iron levels is through phlebotomy (i.e., blood-letting). The easiest way to do that is through blood donation. Sardi’s article heavily cites various studies as does Dr Mercola’s. More clicking led me to another Mercola article, “Donate Blood: You May Be Saving Your Own Life.”


It took me a while to act on Sardi’s advice (I don’t forget about these articles, but it sometimes takes me ages to act on them). I finally got off my duff and donated a few months ago. If you have never donated blood, you may not know that you are given an iron test before you donate. You can’t donate if your iron levels are too low. I half-expected, given my love of steak and burgers, that I would have high blood. Very surprisingly, I had just enough iron in my blood to donate. In fact, they tested me twice just to be safe.

Did blood donation have any effect on my blood glucose levels? I don’t know. There certainly wasn’t a miracle drop in my blood sugar the next day. However, this was all before I launched this website. I was still drinking red wine and my diet was not as strict as today (too much dark chocolate, too many nuts, too much protein). Any marginal drop in my blood glucose levels would likely have been cancelled out by my less than optimal lifestyle. Since my water fast and tweaks to my diet, my blood levels have been much better. Could the donation I made a few months ago be a contributing factor? Maybe. There’s no way for me to isolate that as a factor.

Nevertheless, even if it isn’t helping my sugar levels, blood letting can’t hurt my overall health. If anything, the research suggests it can help significantly. Perhaps more importantly, I can help my fellow man who needs blood.

I’ll keep donating.
