Abstract
BACKGROUND & OBJECTIVES: Millets are rich source of dietary fibre and non-starchy polysaccharides with low glycaemic index (GI), hence can be used as a therapeutic diet. This study was conducted to estimate the effects of a millet-based dosa (foxtail dosa) compared to a rice dosa for breakfast on postprandial glucose levels in patients with type 2 diabetes mellitus (T2DM). METHODS: The GI of rice dosa and foxtail millet dosa was estimated. A total of 105 T2DM participants were randomly selected for the study. The participants were on oral hypoglycaemic agents (OHA) and not on insulin. In this study, each individual served as their own control and experimental group. The postprandial increase in blood glucose was compared after a breakfast of rice dosa and millet dosa. Single and paired t test was used to note the change in blood glucose levels and the level of the significance. RESULTS: The GI of foxtail millet dosa was 59.25 and rice dosa was 77.96. There was a significant reduction (P<0.001) in the postprandial glucose level of patients who consumed a millet-based dosa when compared to those who consumed a rice-based dosa. No significant reduction was observed in the fasting glucose levels. INTERPRETATION & CONCLUSIONS: The results suggested that replacing a rice-based breakfast item with a millet-based breakfast item lowers the postprandial blood glucose levels in T2DM patients. Thus, millets may have a protective role in the management of hyperglycaemia. Further studies need to be done in a systematic manner to confirm these findings.
