TIL The ancient Romans created an artificial sweetener called "Sugar of Lead" by corroding lead in vinegar. It has a mildly sweet taste and also causes brain damage
I can assert that artificial sweeteners do not, in fact, affect insulin at all (at least for this n=1). After a Coke Zero, Diet Coke, or Ghost Energy, my blood sugar remains unaffected for hours (if no other calories are introduced).
Corn, however, in any form, fucks my shit up, blood glucose-wise. Way more than any other starch. No idea why.
Per this article, artificial sweeteners can create an insulin response in the body and can ultimately lead to some degree of insulin resistance. Though, they do state that more studies need to be performed.
Not artificial sweeteners in general... specifically sucralose was tested. Numerous studies have shown it produces an insulin response.
Also, there are a variety of natural alternative sweeteners available now that don't produce an insulin response and have low or no calories, such as stevia, monk fruit extract and allulose. Erithritol as well, though it may have a few drawbacks.
What I mean is, a portion of corn or corn products causes a WAY HIGHER glucose spike with me, than does an equivalently sized portion (by weight or volume) of white rice, beans, milk, or even chocolate cake cake. I don’t know why.
Corn sugar is made up of a pretty large amount of glucose, so eating corn is like eating one of the shock tabs. Which is also a good way to confirm that it's glucose; rice, beans, and chocolate cake all contain pretty small amounts of just glucose, the other sugars need time to break down.
