Sweetened soy milk is bad for diabetics … right? Wrong! Probably!

Ok, a little caveat is needed here. I’ve only done this experiment with ONE type of soy milk, and it’s a brand of soy milk that’s probably only sold in Korea.

So will you get the same results with something like Silk? I have no idea! All I can tell you is what I got here.

Blood sugar reading before drinking: 103

This was late at night, so probably on an empty stomach.

Blood sugar reading after drinking: 130

I was pleasantly surprised by this. I drank basically an entire pint (1.7 cups) of the sweetened soy milk, and my blood sugar only moved a pretty small amount.

I should probably do this experiment again. I like soy milk, especially the sweetened kind, and I’ve started drinking it pretty regularly since I did this test.

I’ll update this later when I do this test again.

Update (Feb. 22, 2020): I did the test again!

Blood sugar reading before eating: 98

This reading of 98 was late at night, so I hadn’t eaten anything in several hours.

Blood sugar reading after eating: 161

This reading was about an hour after I finished the soy milk.

98 → 161 is a pretty big jump, but to be fair, I drank a lot of soy milk. This was over two cups of sweetened soy milk.

And a while back, I also drank about two cups of UNsweetened soy milk.

Blood sugar reading before eating: 128

This reading of 128 was late at night, so I hadn’t eaten anything in several hours.

Blood sugar reading after eating: 142

This reading was about an hour after I finished the soy milk.

So roughly the same amounts of sweetened vs. unsweetened soy milk makes it pretty clear that unsweetened milk results in less of a blood sugar hit. That’s to be expected, but unsweetened soy milk also kind of sucks. I mean, I’ll drink it but … meh.
