never heard of it?
but on filling you up cheap, whole grain and 'brown' stuff stays wit you longer than white...supposedly red potatoes work better than white, I like the idaho though. (and so does my 'full sensor' ok so I am never full really but I am not starving minutes after idaho with bacon and cheese (but I am with white potaotes and cheese..), wait you said healthy? nevermind.
seriously, complex fills you up longer than simple.
