Does a healthy person need to look at the glycemic index of foods?

Apparently, it is advisable to monitor the GI of products not only for diabetics, but also for those who do not want to get type 2 diabetes. A large study found that people who eat a lot of high-GI foods have a 37% higher risk of this disease than those who follow a low-GI diet.

In another study, researchers gave half of the participants acarbose, a substance that slows down the breakdown of starch into glucose. That is, it mimics the effect of a low GI diet. People who received this substance developed diabetes mellitus 36% less often than those who received a placebo. This study included people at high risk of developing diabetes.

Scientists speculate that this association is due to the fact that high GI contributes to a sharp increase in insulin levels in the blood. This, in turn, has a negative effect on insulin receptors in tissues. Their low insulin sensitivity is characteristic of prediabetes and diabetes. Several studies have shown that a low GI diet improves tissue insulin sensitivity.
