I don't doubt that it is a chemical thing and is probably true. Resistant starch is something my doctor told me about years ago. I had years of eating small portions of cold sweet potatoes, cold potato salad and cold rice when dieting and I never lost weight.

So I don't eat cold potatoes or cold rice. I don't think it really helps a person lose any weight.
So I agree with Holly. I do not eat those foods anymore.

Here is an interesting article. Of interest to me, and I'll look more carefully later is the bar chart of resistant starch per 100 grams of food, exactly the way I like to look at things:

www.precisionnutrition.com/all-about
-r
esistant-starch


Potatoes look to be just under 2% resistant starch, and brown rice about the same.Boiled potatoes are 20% carbs when cooked, and the curious thing is we can't eat raw potatoes, and boil them to make the carbs digestible, letting them cool would seem to make a small portion of the carbs go back to being resistant to digestion.

Rice looks similar, unless this chart hasn't yet let the foods cool, but that would be strange because the article specifically mentions potatoes and rice and letting them cool.

JWCOLBY, what reference do you have that 50% of the carbs turn resistant for potatoes and rice?

Resistant starches are starch molecules that resist digestion, functioning kind of like fiber.

Now fibre has two types, soluble (which turns gelatinous in water) and insoluble, or roughage. So resistant starch is more like soluble fibre. Also in theory there is bacteria further down in your digestion, in the small intestine which eat the resistant starch, and provide us with health benefits as a side effect of their existence.

Those "pro-biotic" drinks are supposed to replenish these bacteria, and indeed if you have taken anti-biotics to kill harmful bacteria, you may indirectly also kill these helpful ones.

But what about resistant starch itself? It is interesting that cold potatoes have less starch digestible to humans than warm ones. The starch changes structure in just cooling down.

I've posted the fraction of carbs of various foods here:

Potatoes are 20% carbs, and if half of that is resistant to digestion when cooled, that is 10%, still too high to make my 6% guideline, so just a taste of this.

Rice is 27.8% carbs, and when cooled half of that would be 13.6%, definitely much too high for me to consider it.

Better cooled, but still ...

In another discussion JWCOLBY posted:
--------------
Has anyone been reading about resistant starch? White potatoes cooked, then allowed to cool? Rice, cooked then allowed to cool? The cooling apparently converts about 50% of the starch to "resistant starch" which passes all the way to the colon before being digested by the biome into short chain fatty acids, i.e. Butyrate, which, I am reading, is mostly used by the colon lining as it's own energy source.

Hmmmm...

So I've kicked of that discussion here.
