Diabetes Mellitus is a fast-growing disorder in the current scenario commonly affecting all age groups

especially elder groups. The high blood glucose can be kept in control with nutraceutical foods. The present

study is aimed to formulate a nutritionally rich cookie with Costus igneus leaf extract and to determine the

effect of cookie consumption on decreasing blood glucose levels in type 2 diabetic patients. Cookies made

with Costus igneus leaf powder etc. were analyzed for proximate analysis and phytochemical analysis with

standard procedures. A total of 30 Type-II diabetic patients were selected for the study whose demographic

variables and blood glucose levels were measured on the first day and after 15 days, 30 days of cookies

consumption. The proximate and physic-chemical analysis showed cookies contain high amount of secondary

metabolites including antioxidant compounds. Among the 30 study subjects, the mean levels of FBS and

PBS were decreased significantly in all the four groups from day 0 to day 30 which indicates that C.igneus

cookies consumption had good effect in reducing the blood glucose levels. However the HbA1C has been

decreased by one unit in all the four study groups. The cookies made with Costus igneus plant material have

good antimicrobial, antioxidant and antidiabetic activities and can be used as a therapeutic and functional

food source for the treatment of overweight, obesity and diabetes.
