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 personalised prevention and treatment strategies for prediabetes and diabetes.
