If you’re curious about your blood sugar fluctuations, you can buy continuous glucose monitors over the counter in Canada (Costco, Shoppers). You wear the sensor for two weeks and scan before and after meals to see how different foods affect you. (In the USA, I think they’re still prescription only.)

Sometimes the results are unintuitive. For example, I saw higher blood sugar fluctuations from beans than cake. You can also moderate the blood sugar spikes of pancakes by upping protein or fat in the meal.
