Summary:Objective: To compare the glycemic index (GI) of three varieties of Chenopodium Quinoa Wildenow (CQW) from Peru. Materials and methods: - 26 participants apparently healthy volunteers living in Lima: a quasi-experimental study according to the ISO 26642 standard was conducted. Exposure variables were three varieties of quinoa: Blanca CQW Salcedo (CQW - B), CQW Black Collana (CQW - N) and CQW Red Pasankalla (CQW - R). Capillary blood samples were taken seven times over a period of two hours and analyzed by the glucose oxidase method. IG estimation was based on the areas under the curve obtained by the trapezoidal method. The comparison of GI values was performed by multiple analysis of variance for dependent samples (MANOVA). Results: The GI of CQW - B and CQW - N were classified as medium-GI, with values of 63.1 ± 22.3 and 62.3 ± 22.5 respectively, and CQW - R was classified as high-GI with a value of 74.8 ± 29.7. No statistically significant both crude level (p = 0.33) differences were found, as adjusted by age and sex (p = 0.27). Conclusion: IG quinoa varieties studied is not low and therefore should be incorporated in the diet therapy of patients requiring glycemic control through proper portion control advice from a dietitian nutritionist.
