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.
