1. 39 2. M 3. Diabetes II, diagnosed approx. 21 yrs. ago and has on the most part never been under control., readings hovering around 400 mg/dL. Are seeing medical problems now: ED, my penis inflates only to about 1/4 the size and the area just below the "head", seems "closed" off, "spongy" inflator damage???, gum disease and most recently, lots of vision problems with mainly right eye: diagnosed with uveitus. interestingly enough, r eye's pupil is dialated 50% bigger than left. l. eye is blurred and objects on l. eye seem to be drastically distorted. I know one of the harmful effects of diabetes is that it damages nerves, blood vessels, etc. I know I don't have my diabetes under control right now, but to help my blood vessels from further damage or to help regenerate?, could eating dark chocolates help? I searched the net and there's info. that dark chocolate has flavonoid that helps regarding blood vessels and flow. Is there truth in it? But there could be a price to pay since chocolate has sugar, a no no for diabetics, the good that could be extracted from chocolate can be nullified by the sugar, and saturated fat. OK, to eat dark chocolate?
