Introduction: Quinoa is a pseudocereal containing low glycemic index carbohydrates, dietary fiber, high biological value protein, phytosterols, and n-3 and n-6 fatty acids, which has generated interest in prediabetes nutritional interventions. This randomized (2:1), placebo-controlled, double-blind study evaluated the effects of processed quinoa on body mass index (BMI), glycated hemoglobin (HbA_1c), fasting plasma glucose (FPG) and the satiation and fullness (complete) degree in prediabetic patients. Material and method: Thirty patients were randomized (2:1) in two study arms: Kuska Active product (processed quinoa) and placebo (maltodextrin), with an intake period of 28 days. BMI, HbA_1c and FPG were determined before starting treatment and at 28-day intake. Satiety and fullness sensation were just assessed by visual analog scale (VAS) at the day 28. ANOVA was performed for repeated measures with two factors to study (within-subject factor: time; intersubject factor: product consumed) to demonstrate the effectiveness of processed quinoa on the study variables. Results: Twenty-nine patients (placebo, n = 10; quinoa, n = 19) completed the study, and the quinoa group shows a significant decrease in BMI (p < 0.05) and HbA_1c values (p < 0.001), and an increase in the satiation and fullness (complete) degree (p < 0.001). No significant differences were found in FPG levels from baseline to post-intake period. Conclusions: The results show that processed quinoa intake during 28 days decreases BMI and HbA_1c levels, maintains FPG levels, and increases the satiation and fullness (complete) degree in prediabetic patients.
