Researchers from The Pennsylvania State University (USA) conducted a systematic review and meta-analysis of randomized controlled trials to examine the effect of tree nuts and peanuts on markers of glycemic (blood sugar) control in adults.
A total of 40 articles (clinical trials) were included in this review. Fasting glucose, fasting insulin, glycated hemoglobin (HbA1c), and homeostasis model assessment of insulin resistance (HOMA-IR) were determined for nut consumption groups and also the control groups. All of them are biomarkers that may help on the diagnose of diabetes mellitus.
The study concluded that peanuts and tree nuts significantly decreased HOMA-IR and fasting insulin. Findings suggest that nut consumption may play a role in improving insulin sensitivity and thus delay the development and progression of type 2 diabetes.
