Polyphenol extract from peanut skins has been demonstrated to inhibit α-amylase activity in vitro. Hence, the aim of this study was to evaluate the regulatory effects of the peanut skin extract (PSE) on blood glucose and body fat by a double-blind, placebo-controlled, clinical study. Subjects with simple obesity (body mass index [BMI] ≥27 or body fat ≥30%) ingested 4 PSE (n = 16) capsules or placebo (n = 14) a day for a total of 6 weeks. Anthropometric measurements (body weight, body fat, blood pressure) and blood biochemical markers including fasting blood glucose (FBG), albumin, total cholesterol (TC), triglyceride (TG), HDL-C, LDL-C, creatinine (Cr), blood urea nitrogen (BUN), AST, ALT were examined every three weeks. Also, 5 subjects were randomly selected for MRI scans to examine the distribution and thickness of abdominal fat layers before and after the trial. The results revealed that after 6-week PSE intake, body weight and body fat decreased 0.33 kg and 2%, respectively. In addition, for the subjects who have abnormal FBG (≥100 mg/dL), their FBG had a significant improvement by 7.4% without changing the levels of other blood biochemical markers after the 6-week PSE supplementation. Therefore, the results demonstrated that PSE has positive effects on blood glucose and body fat regulations.6enEvaluation effects of peanut skin extract on blood glucose regulation and body fat reductionjournal article
