Hypoglycaemic and hypolipidaemic effects of low GI and medium GL Indian diets in type 2 diabetics for a period of 4 weeks: A prospective study

Abstract

This prospective study reports significant hypoglycaemic and hypolipidaemic effects in type 2 diabetic subjects who were provided the complete diet plan to be on low glycaemic index (GI) and low-medium glycaemic load (GL) Indian vegetarian snacks and mixed meals for 4 continuous weeks. Five millilitres of fasting blood sample drawn at weekly intervals for 4 weeks were analysed for blood glucose, HbA1c and lipid profile. Four weeks later mean blood glucose level of 173.6 mg% decreased to 137.8 mg%, HbA1c of 8% also decreased to 7.1% which reflected the blood glucose level during the study period and hence correlated well with the fall in blood glucose level. Triglyceride level of 244.5 mg% decreased to 164.7 mg% (p < 0.0001) and total cholesterol of 173.5 mg% decreased to 134.6 mg% (p < 0.0001). High-density lipoprotein cholesterol of 33 mg% increased to 39.8 mg% (p < 0.003), very low density lipoprotein (VLDL) cholesterol of 48.9 mg% decreased to 32.9 mg% (p < 0.0001) and low-density lipoprotein cholesterol of 90.1 mg% decreased to 64.3 (p < 0.009). This significant outcome can be improved further if compliance to low GI and low-to-medium GL diet is continued. This may achieve desired glycaemic control and that's limit oxidative stress.
