Tindall AM, et al. - Researchers analyzed 40 randomized controlled trials (n=2,832 unique participants) that reported on the impact of tree nuts and peanuts on markers of glycemic control in adults. Of 1,063 potentially eligible articles screened in duplicate, 40 met eligibility for inclusion, and data from these articles were obtained in duplicate. The investigators used the DerSimonian and Laird random-effects method to determine the weighted mean difference (WMD) between the nut intervention and control arms for fasting glucose, fasting insulin, glycated hemoglobin (HbA1c), and homeostasis model assessment of insulin resistance (HOMA-IR). According to findings, significantly decreased HOMA-IR and fasting insulin was associated with the consumption of peanuts or tree nuts. Overall, they did not note any impact of nut consumption on HbA1c or fasting glucose. They concluded that nut consumption may improve insulin sensitivity.
