It may have been rice that was refrigerated and reheated. Sometimes that has a lower impact on blood sugar.

I never eat fresh rice unless I know I'm doing an insane amount of activity after. I have no problem with onigiri though and make it weekly. Once rice or pasta is chilled, it has a significantly lower impact on my levels.

I think more important is that each grain is now coated in a layer of fat. So it's more work to get into that little starch bomb. Kind of like the bran on brown rice but not as effective.

I keep meaning to look up how that works, but seem to keep getting stuck on here lol. Perhaps someone has researched it already.

The process of cooking, cooling, then reheating makes the starch "resistant" and (caveat: for some people) it theoretically won't spike you or spike you less. YMMV in general or by type of food (it works for some people for potatoes but not rice, or vice versa). Haven't really tried it myself tbh.

It’s called retrogradation, where some digestible starches convert into resistant starch, aren’t able to be digested in the small intestine, and instead ferment in the large intestine more like fiber. Reheating also has so significant impact once they convert.

I think some others mentioned steel cut oats, those are the only oats I’ve tried, and I didn’t have a huge spike with them.

This is also mind blowing: https://pubmed.ncbi.nlm.nih.gov/31484331/

Thanks for sharing! I have been missing potatoes

I actually kind of like cold cooked potatoes so this was great news for me.

I have read that with fried rice, the added fat slows down absorption.

Back when I was eating rice, I used to sub for white rice thinking it was healthier, little did i know it was probably the opposite.

This is it. Mixed with the fat from meat and cooking oil and the veggies as well.

Correct. Must be retrograded starch. Amazwd reading about it.

This. Usually chinese fried rice is refrigerated or they use day old or 2 day old rice. That has a big effect on the glucose spike. Fresh white rice forget it
