I've recently been reading about the health benefits of blackstrap molasses and am pretty intrigued. Not only is it a great source of iron and calcium, but it's also a source of potassium, magnesium, copper, and manganese. Many people claim to have reversed their gray hair with it. I bet this is at least partly due to the copper content, as copper deficiency can lead to prematurely gray hair.
Copper, an essential component of many enzymes, plays a role in a wide range of physiological processes including iron utilization, elimination of free radicals, development of bone and connective tissue, and the production of the skin and hair pigment called melanin ... Using two teaspoons of blackstrap molasses to sweeten your morning cereal and the coffee or tea you drink during the day will supply you with 14.0% of the daily recommended value for copper. whfoods.com
I'm going to buy some today and will report back. I'm not sure how I'm going to eat it - it looks like mixing it in water is the most popular method. Does anyone who's tried it have any suggestions?
2013 update: Since writing this article seven years ago, I've been using Plantation Organic Blackstrap Molasses with great results.
