Determination of glycemic index blood glucose response among young healthy adults after consuming white sweet potatoes (Ipomoea batatas) and cempedak seeds (Artocarpus interger)

Abstract

This randomize cross-over study was carried out to determine the blood glucose responses among 11 healthy young adults age 21-13 years old, after consuming different test meals which are cempedak seeds and white sweet potatoes in different occasions. Simple randomized sampling has been done among student from Universiti Malaysia Terengganu (UMT). After 8-10 hours fasting, subjects were asked to eat each test fruit and reference carbohydrate (glucose), at different time within 15 minutes. Finger prick capillary blood sample were taken at 0, 15, 30, 45, 90 and 120 minutes after eating the meals. The blood glucose response was obtained by calculating area under the curve (AUC) This study shows that peak value of blood glucose response of all fruits which are cempedak seeds and white sweet potatoes, and reference food was at 30 minutes. Thus, between male and female after consuming white sweet potatoes and cempedak seeds also have the high peak value at time 30 minutes. Cempedak seeds have the lowest (1.74±().59 mmol/L) as compared to white sweet potatoes (1.90±0.76 mmol/L).The Glycemic index was determine according to the standardized methodology. This study showed that both test meals, could be categorized as having medium GI. The GI of white sweet potatoes (01=67) and cempedak seeds (GI=58), were lower than glucose (reference food) that have GI= 100 In conclution, the results of the study shows the suitable fruits to be taken by diabetic patient.
