Quinoa Improves Glycolipid Metabolism and Glucose Fluctuation Based on β-Cell Function in Early-stage Type 2 Diabetes (QIGMAGFBOβFIET)

December 28, 2025 updated by: kuanxiao Tang, Qilu Hospital of Shandong University

The goal of this clinical trial is to explore whether quinoa diet can improve glycolipid metabolism and glucose fluctuations in patients with early-stage type 2 diabetes mellitus (T2DM) and observe its impact on islet β-cell function and insulin resistance in patients with early-stage T2DM (diagnosed according to the 1999 WHO criteria, disease duration <5 years, HbA1c 6.5%-10%, no history of insulin therapy, aged 20-70 years).

The main question it aims to answer is:

Can quinoa diet reduce blood glucose (fasting blood glucose, postprandial blood glucose, glycosylated hemoglobin), improve lipid metabolism (cholesterol, triglycerides), and stabilize glucose fluctuations (time in range, time above range) in patients with early-stage T2DM? Does quinoa diet improve islet β-cell function (HOMA-β) and insulin resistance (HOMA-IR), and reduce the need for oral hypoglycemic medications? Comparison group: Researchers will compare the quinoa diet (QD) group (replacing traditional starchy foods with quinoa products) vs. the regular diet (RD) group (conventional diet) to see if quinoa diet demonstrates better metabolic improvement and medication reduction effects.

Participants will:

Be randomly assigned to the QD group or RD group. Undergo oral glucose tolerance tests (OGTTs) and continuous glucose monitoring (cGMS) at baseline and after the intervention.

The QD group will consume quinoa-based foods (noodles, blended powder, cookies) as substitutes for staple foods, beverages, and snacks for 14 weeks, documenting daily intake in a record book.

Both groups will receive standardized dietary and exercise education, with monthly follow-ups for food distribution and data collection.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: the quinoa diet (QD) group
The QD group replaced part of their staple foods with quinoa noodles, mixed flour, and biscuits. The intervention lasted for 14 weeks. Regular monitoring of indicators such as blood sugar, blood lipids, insulin resistance (HOMA-IR), and β-cell function (HOMA-β) was conducted, and the use of medications was recorded.
Dietary supplement: Quinoa-based foods
Quinoa-based foods included three varieties: quinoa noodles (80 g per bag; the ingredients included quinoa powder, red bean powder, black wheat powder, black mung bean powder, and edible salt, with quinoa powder comprising 15% of the total produced by Shandong Tangren Duoyi Biotechnology Company), blended powder (15 g per bag; the ingredients included quinoa, rye wheat, black mung beans, adzuki beans, black sesame seeds, chickpeas, konjac flour, and mogroside, with quinoa flour comprising 20% of the total produced by Shandong Tangren Duoyi Biotechnology Company), and cookies (24 g per bag; quinoa, rye, adzuki beans, black sesame seeds, vegetable oil, and salt, with quinoa comprising 20% of the total produced by Shandong Tangren Duoyi Biotechnology Company). These products serve as substitutes for the common starchy staples, soups, porridge, and snacks typically consumed by T2DM patients. This substitution did not alter patients' daily eating habits; rather, it simply replaced tradition
No Intervention: the regular diet (RD) group
