Introduction: Hormonal changes during menopause involve in the development of type 2 diabetes. Therefore, prevention of diabetes and its complications during menopause is of particular importance. The effects of barley (Hordeum vulgare L) in maintaining blood glucose and blood insulin have been previously reported. This study was designed to investigating the effect of roasted barley flour consumption on the blood sugar level of prediabetic postmenopausal women. Methods: This randomized controlled trial study will be conducted on 68 prediabetic postmenopausal women referring to community health centers in Gonabad, Iran. All participants will complete a demographic questionnaire and their fasting and two-hour postprandial blood glucose levels; and HbA1C will be recorded. The intervention group will receive 60 grams daily (20 grams before each meal) of roasted barley flour for four weeks, while the control group will receive no intervention. Fasting blood glucose and two-hours postprandial blood glucose will be checked by venous blood sampling at baseline, two and four weeks after intervention. All participants will complete the three-day food intake record and Beck's physical activity questionnaire during the study. Data analysis will be done using the statistical package for social sciences (SPSS) software (version 16) and p value less than 0.05 is considered significant. Conclusion: In case this study proves the effectiveness of roasted barley flour in reducing blood glucose, daily consumption of this compound can be recommended for prediabetic menopausal women.
