Despite a proportion of people not reacting well to resistant starch, its proponents keep insisting that we ALL need to persist in trying it. Getting our fiber from sources that make us feel good, they say, is not enough! They demand that we join them in their flatulent bliss.
No thank you. My bowels are happy with the quantity and quality of my usual choices.
In my case, i haven't had a course of antibiotics since the early '90s when i had major surgery. I use raw milk and create whey for pickling favorite vegetables as often as i can, as well as enjoying home-made kefir and yogurt (well-fermented, so as to convert as much of the sugars to acids as is consistent with tastiness). I know that if i get a case of loose bowels from a virus or restaurant food, a hefty dose of probiotic is helpful, and i keep a bottle of some good stuff on hand for just-in-case. I'm not afraid of dirt on my hands, and i don't freak at it being under my fingernails. AND i don't believe in using hand-sanitizers. I have pretty good faith that my gut-bugs are in decent condition.
If it were a case of taking a teaspoon of potato starch per day, i might try it and measure glucose responses, just out of curiosity (i have my share of THAT quality) -- however, a dose of 20-30 grams is needed to show benefit and that's THREE TABLESPOONS, more or less -- damned if i'm interested in working my way up to that, just to see if it benefits ME.
But the biggest brake on my curiosity is ... "fear" of outrageous gas and bloat! :-) I have enough trouble if i overdo lettuce or fruit! A number of vegetable sources seem to set off FODMAP-type problems with me, and it's just NO TEMPTATION to test myself some more! To admit to a little vanity, i'm very pleased with the flatness of my stomach compared with other women my age -- i honestly don't want to screw THAT up, either.
So, no -- despite the positive reviews at MDA, i think i'll pass when it comes to trying out RS.
