Whole grain intake and insulin sensitivity: evidence from observational studies.

Frequent consumption of whole grains may help enhance insulin sensitivity in individuals.

​Insulin resistance is the hallmark of type 2 diabetes. This meta-analysis assessed the effect of high intake of whole grains on insulin sensitivity. Researchers pooled data extracted from eligible studies. 

Researchers observed that habitual consumers of whole grains experienced significant improvement in their body's sensitivity to insulin. The data from this study support the hypothesis that a high whole grain diet may have a positive effect on insulin sensitivity.
