I also find that the capsaicin diabetes blood glucose lowering benefits extend beyond the next day fasting blood glucose lowering (which fasting blood glucose lower effects I see the next day after I have had my final dinner meal with habanero peppers as a cooked dinner meal according to my diabetes recipes pages).
In this case, my tests were to have the same diabetes dragonfruit salad meal which I normally have but I had either meals with chile pepper or without chili peppers on the day prior to the dragonfruit salad meals.
