PG - 1392-1401 LID - S0271-5317(16)30673-X [pii] LID - 10.1016/j.nutres.2016.11.007 [doi] AB - Tartary buckwheat (TB) is rich in protein, dietary fiber, and flavonoids and has been reported to affect type 2 diabetes mellitus (T2DM) in animal experiments, but limited information on the benefit of TB as a whole food in T2DM patients is available. Thus, we tested the hypothesis that a daily replacement of a portion of the staple food with TB will improve risk factors of T2DM, including fasting glucose, insulin resistance, and lipid profile. In a parallel, randomized, open-label, controlled trial, 165 T2DM patients were randomly assigned to a control diet group (DC group; systematic diet plans and intensive nutritional education) or a TB intervention group (TB group; daily replacement of a portion of staple food with TB food). Blood samples and diet information were collected at baseline and after 4 weeks of intervention. The TB group decreased fasting insulin (2.46-2.39 Ln mU/L), total cholesterol (5.08-4.79 mmol/L), and low-density lipoprotein cholesterol (3.00-2.80 mmol/L) compared with the DC group at 4 weeks (P<.05). No significant differences in blood glucose or glycated hemoglobin levels were noted between the TB and DC groups. In addition, subgroup analyses based on daily TB intake dose showed a reduction in insulin, total cholesterol, and low-density lipoprotein cholesterol, but also insulin resistance was observed when TB intake dose was greater than 110 g/d. These results support the hypothesis that TB may improve insulin resistance and lipid profile in T2DM patients. CI - Copyright (c) 2016 Elsevier Inc. All rights reserved.
