Black stool usually: Means melena, which means bleeding from upper GI tract. I suppose black food can make your stools black if you eat enough of it, but don't take that chance. Get your stool tested for occult blood. If you are bleeding from your GI tract, it is something serious. Get to emergency dept now.
