http://www.nutritionj.com/content/9/1/55 Basically the information is that a doctor noted that a patient felt better after eating dark chocolate and did a study of ten patients in his practice. THey ate 15 grams of DARK chocolate three times a day. After eight weeks they reported improvement, enough improvement where two of them went back to work. Some articles state that the reason MIGHT be because it increases serotonin. I can't begin to believe that because that would just mean they emotionally felt better, which is not enough to go back to work. This article does not claim that. I am venturing to guess another possible reason for the improvement. See my other thread on biofilm-forming protozoa. The protozoa (it's biofilm) keeps nutrients from entering the body. Perhaps the chocolate is toxic to this protozoa. (Chocolate is toxic to dogs and cats). It's just a guess, but it's a possibility. I do believe that when I got sick it was viral. It is possible that the virus opens the body to other infections such as the biofilm producing protozoa. It creates it's film, keeping nutrients from entering the body, creating a starvation of nutrients which reduces are energy to nil. This is guesswork. I'm trying to figure this out from my experience with this illness. I don't have a whole lot more to go on. I have been trying eating dark (85%) chocolate for 6 weeks now and my energy level is up. Not enough to work, but I'm seeing improvement. Is it the chocolate? I don't know for sure. I'm always trying so many things to get well. Yes I know I'm supposed to try them one at a time so I know what's working, but sometimes I do get impatient with doing that. My life is only so long here. It's supposed to take the full six weeks, with little or no improvement to start. The people in the study did not gain any weight. I'm finding the fat in the chocolate is cutting my appetite, so that may account, and anyway, someone figured out I was only adding 300 calories to my diet, daily. I started out giving this a try as a joke. I've tried so many horrible awful things to try to get well. It would really be a joke if just eating chocolate would do it. I had to try it just to say I tried something easy to do. If this ended up curing me it would be a big joke indeed!!! I'd love it if others wanted to give this a try and report back on if it did anything for them. The nice thing about it is you don't need a prescription, and there aren't any side-effects (unless you get the good chocolate and eat too much of it like I did one week, and then I gained some weight, but as long as I've stuck to the 15 grams 3 times a day I have not gained any weight). If nothing else, it's a good excuse to eat chocolate.
