Evaluation of glycemic response of ten local meals commonly consumed from Chad

Diabetes mellitus is a metabolic disorder characterized by the presence of chronic hyperglycaemia accompanied by greater or lesser impairment in the metabolism of carbohydrates, lipids and proteins, including defects in either insulin secretion or response. The function of pancreatic cells gradually declines before the onset of clinical hyperglycemia. Its prevalence is increasing everywhere, especially in the developing countries due to the consumption of unknown glycemic index (GI) foods. Thus, the present study aimed to determine the GI of some local meals from Chad. In this purpose, ten meals were investigated and 60 non-diabetic volunteers were recruited in the present study. The proximate composition and the GI of these meals were determined. Results showed that 5 main ingredients (Hibiscus esculentus, Ipomea batata, Hibiscus sabdariffa, Corchorus oletorius and seeds of Parkia biglobosa) differentiate the meals. Soluble sugars and total carbohydrates levels showed a significant (p
