Strange. I'm right on the borderline of being a supertaster, but I don't find fatty foods distasteful at all. I find spicy foods or really strong flavors distasteful, because they completely overwhelm my taste buds. But things like cream and butter have a pretty mild taste and I think they're wonderful. Of course, so do bread, chicken fingers, and french fries. I'm definitely not leaner than the general population (but I'm working on it).
Maybe they mean people who are sensitive to texture or "mouth-feel"? I know plenty of people who won't drink cream because they hate the heavy, coats-your-mouth feeling of it. But that has nothing to do with the flavor at all. I think Yahoo is confused.
