Jeffrey Bland, PhD, describes Day 1 of a continuous glucose monitoring (CGM) study where participants consumed 100 grams of white bread on a fasted stomach to establish a baseline glycemic response. Blood glucose was recorded at time 0 and at 30, 60, 90, and 120 minutes; the postprandial spike rose and fell relatively rapidly and will serve as the baseline for the next 13 days of testing.
Okay, as promised, here I am, part of the glycemic test that we're doing with the continuous glucose monitoring. Got it in my arm today. So today was our white bread day. Now, can you imagine having to consume 100 grams, that's almost a quarter a pound of white bread flour this morning to get our baseline. But that's what we all did. We're a committed group of scientific investigators, citizen scientists. So this morning, we all took on a fasted stomach 100 grams of white bread. I took the crust off, so I keep homogeneous material. And then we measured our blood sugar. Time, zero. Then 30 minutes, 60 minutes, 90, and 120 minutes with our continuous glucose monitor. And in so doing, lo and behold, we got some very, very fascinating results that I will show you. It looks like this. You can see the Andes mountains there. That was the spike of the postprandial glucose, fortunately came down as rapidly as it went up. But now we use that as our base for the following subsequent numbers of days, the next 13 days that we're going to test other subjects. So hold on, we'll do more each day, thanks.
