Blood sugar response to carbs may signal prediabetes risk

Blood sugar responses after food, especially carbohydrates, may indicate metabolic health status as well as signal the risk of prediabetes, according to a study.

Researchers from Stanford University in the US explained that the differences in blood sugar response patterns among individuals were associated with specific metabolic conditions such as insulin resistance or beta cell dysfunction — both can lead to diabetes.

The findings, published in Nature Medicine, suggest that this variability in blood sugar response could lead to personalized prevention and treatment strategies for prediabetes and diabetes. "This study suggests that not only are there subtypes within prediabetes, but also that your subtype could determine the foods you should and should not eat," said Michael Snyder, Professor in Genetics at Stanford Medicine.
