Formulation and assessment of chickpea pulao using fenugreek seeds and Indian rennet to improve blood glycemic levels

Abstract

AbstractDiabetes is becoming a significant health concern in Asia, where the prevalence has reached alarming levels. An important contributing factor is the consumption of high‐carbohydrate foods, including rice, bread, etc. These high‐carbohydrate foods pose a major risk to public health due to their impact on postprandial hyperglycemia. This research aimed to formulate a chickpea pulao (cooked Indian–Pakistani rice dish) and to evaluate its effects on postprandial blood glucose levels in type 2 diabetic individuals. Antioxidant potential and total phenolic contents of herbs at different concentrations (1, 3, 5, 7, and 9%) were measured through DPPH and Folin Ciocalteu assays. The antidiabetic potential was tested by α‐amylase and α‐glucosidase inhibition assays. After sensory evaluation, the best‐chosen concentration was used to formulate the chickpea pulao. The study trial was advertised under “DP trial,” and 12 participants were recruited. A single‐blind randomized cross‐over trial was conducted for 3 weeks with a one‐week wash‐over time in between. Participants' preprandial and postprandial blood glucose levels were recorded for control and intervention recipes. Results indicated that both fenugreek seeds (FS) and Indian rennet (IR) showed good antioxidant and hypoglycemic activity (p = .000) in raw and boiled extracts. For DPPH, the IC50 values of unboiled and boiled combined (FS + IR) extracts were calculated as 7.4% and 8.02%, respectively. Similarly, for α‐amylase, the IC50 values of combined IR and FS unboiled and boiled extracts were 6.58% and 6.83%, and for α‐glucosidase inhibition assay, the values were measured as 14.98% and 16.24%. The single‐blind randomized cross‐over trial showed that consuming the intervention recipe significantly reduced postprandial hyperglycemia (p = .000) in type 2 diabetic participants. The intervention recipe decreased hyperglycemia by approximately 15% daily compared to the control recipe. Incorporation of hypoglycemic herbs into dietary patterns can work as an adjunct therapy for diabetes management, especially in populations with a high prevalence of this disease.
