Oral glucose tolerance tests (OGTTs) and dynamic blood glucose monitoring were performed before and after the intervention.Results: Ninety-seven percent of patients adhered to the dietary intervention plan involving quinoa. In addition to postprandial blood glucose and cholesterol, fasting blood glucose, glycosylated haemoglobin, triglycerides, and insulin resistance decreased in the QD group. The reductions in postprandial blood glucose (4.57 ± 2.7 mmol/L vs 2.2 ± 2.8 mmol/L, P < 0.001) and glycosylated haemoglobin (0.86 ± 0.24 vs 0.28 ± 0.23, P =0.042) as well as the increase in the time in range (94.52 ± 4.88% vs 87.83 ± 9.9%, P < 0.05) were more pronounced in the QD group. The QD group achieved a higher rate of medication reduction or withdrawal (28.6% vs 7.1%, P =0.036). Multivariate analysis indicated that HOMA-β and quinoa consumption were the primary risk factors.Conclusion: β-cell function is the key factor influencing quinoa’s ability to improve metabolism and achieve diabetes remission in patients with early-stage T2DM.Keywords: type 2 diabetes mellitus, quinoa dietary intervention, glycolipid metabolism, glycaemic fluctuations
