Isn't a certain kind of fiber also supposed to be good for lowering cholesterol? I don't remember if it's soluble or insoluble, but I think it's whatever you get from oatmeal (and Cheerios).

But yeah, I would say to take a few deep breaths, schedule the re-test and then do your best to forget about it until you have the second set of results. The freakishly high HDL result could indicate that this last test was skewed for some reason.

Good luck!!
