Go figure eh? Considering my thing for dark chocolate and milk, read the last lines of this post, and then take a gander at the last paragraph below.
"A recent study shows that people who regularly consume 70% dark chocolate (about 20 g per day) show a marked improvement in blood flow, while no improvement is observed in those who eat “processed” chocolate, which contains very little cocoa paste. It seems that the positive effect of dark chocolate is linked to a property in its polyphenols that releases a chemical messenger, nitric oxide, which increases arterial dilatation, at the same time improving blood flow and reducing platelet aggregation.
However, it is important to note that previous studies have shown that milk prevents the absorption of dark chocolate’s polyphenols, thereby neutralizing its beneficial effects. Milk contains large amounts of casein, a protein that interacts with polyphenols and prevents them from being efficiently absorbed by the intestine. It is therefore always preferable to consume dark chocolate unaccompanied by milk. "

Furthermore, being that I love milk... there is a distinct possibility that I am perhaps in denial about being slightly lactose intolerant.
