Ah, Magic Health Superfoods (TM)! They come and they go, and the poor suckers who think there's a shortcut to weight loss and optimal well-being are out a lot of money and, sometimes, physical discomfort, as well.
I'm not saying that paleo food is all you need, as some of the innocent young primalists do -- it's well-documented that some people do not absorb nutrients well enough to get what they need, and MORE who don't convert them, in their bodies, in textbook fashion! It may be imperative to take specially-formulated vitamin, mineral, enzyme or other supplements, and take them in combination (or not) at the right times, to get the right molecules to go to the right places.
But instead of taking your potato starch (at least a couple of tablespoons per day!) plus whatever else kind of cooked starch and this fiber, and that fiber ... is there any reason that eating, say ...VEGETABLES might not provide the benefits of all of them, in one convenient package?
It has become glaringly apparent to me that different people tolerate different oligo- and polysaccharides in widely different forms and quantities. Here's a novel idea: each of us chooses the vegetables and/or fruits which we know we can tolerate, and EAT THOSE! Not too much ... plants if you like 'em. Unless i've been grossly misled, they all contain fiber and starch in varying amounts.
