Gut irritation from day old sweet potatoes?

Commented on April 30, 2014

I'm not sure yet, but I seem to be noticing a pattern of gut irritation and indigestion when I eat baked and/or microwaved orange sweet potatoes a couple days after cooking. Anyone else noticed this? Any reason I might be experiencing this? Or maybe it's something else. Still trying to pinpoint it but it does seem to point back at the couple-day-old refrigerated sweet potatoes...

I usually eat them without the skin FWIW.

Yep eating still hot, or at least warm after cooling for a bit. I do like cold okinawan purples but not so much the orange flesh standard yams...

"...even increased if you again let the potatoes cool", True (i think its called RS3), but you need to let them cool (go cold) for the starch to turn back to RS. i thought Metho was talking about them still being hot. pubmed , wikiRS3

Assuming you're okay eating cold potatoes that makes it strange, as uncooked potatoes should have significantly more RS.

On a paranoid note: Maybe the microwave is making your potatoes radioactive and slowly killing you as you consume them?!?!

Yes (at least that is what i have read)

Not what I've read, check out the resistant starch thread at MDA, they seem to suggest that the RS formed while the potatoes are cooling is maintained through the next heating and even increased if you again let the potatoes cool. ( not as dramatic an increase as the first cooling, also cool to below 10 degrees for ideal results )

"If I microwave the potato (until steaming hot) doesn't that revert the RS back to digestible starch?"...Yes (at least that is what i have read)

I usually eat it hot. If I microwave the potato (until steaming hot) doesn't that revert the RS back to digestible starch? Also, I have been okay eating cold okinawan purples and even cold white potatoes.

When you cook then cool potatoes you increase the resistant starch content, usually people do it intentionally. I imagine this could cause digestive issues in compramised individuals??

Could easily be a reaction to the resistant starch in cooled sweet potatoes. Digestible starch of a fresh-baked sweet potato (or potato, rice, etc) turns to resistant starch in the cooling process, which our digestive enzymes can't break down. It tends to keep its bulk and then get broken down by the various populations in the colon. For some people resistant starch is great, helping with regularity, mood, and weight loss. For others, not so much.
