Got a reminder today how my blood glucose reacts to carbs.
After fasting last night from dinner on and this morning (with a level of 5.4), I went for lunch at a South Indian biryani place with daughter & son-in-law -he's south Indian). I did not have any biryani, rice or naan. or dosa. I had lollipop chicken & gongura (sorrel) chicken curry & masala chai (unsweetened). I added a bit of Stevia to the chai (my own, no dextrose in it unlike the packets of artificial sweetener they gave me.) The lollipop chicken was a mistake, it was breaded with either chickpea flour or wheat flour ( I thought it would be like tandoori chicken, no breaded but it was. I ate it since I forgot to ask). Checked 2 hours after, I got a spike of 7.6!
I assume it was because of the breading. As well, Indians don't usually use flour to thicken their sauces (sugar or jaggery isn't usually added either even with sour ingredients but may use nuts. I wonder if there were ground cashews in the gongura chicken curry? I don't think gongura (sorrel) causes spikes, does anyone know? As well, the milk in the masala chai probably didn't help. I'll have to try it again with a low carb meal. Eating to add: apparently they sometimes use rice flour for the breading for fried items.

It's the most likely culprit.
3 hours later I'm reading 5.9. Dinner tonight is a low carb chicken stir fry that has minimal effect on my blood sugar.
