Background : The selection of food carbohydrate use the concept of glycemic index (GI) and glycemic load (GL) can help prevent a variety of degenerative diseases, diabetes, and useful for athletes, obese and healthy people. Purpose :This study aims to determine the GI and GL of purple sweet potato fried and steamed in healthy subjects and how the effects of processing on the GI and GL Method : Determination of GI using 10 subjects were asked to fast for 10-12 hours on the night before the study and then measure fasting blood glucose levels. Furthermore subjects were asked to consume food test (white bread, sweet potato fried and steamed purple) of 50 g available carbohydrate and blood samples be taken every 30 minutes subjects (30, 60, 90, da 120 minutes) 1-2 uLfinger prick blood cappilarry samples method. Determination of BG based on calculation of GI value multiplied by the number of available carbohydrate in 1 serving the food and divided by 100. Result : The grades GI of purple sweet potato fried (105.39 ± 13.41) and steamed purple sweet potato (123.55 ± 11.19) were classified as high glycemic index foods (> 70) did not show a statistically significant difference (independent t-test p> 0,05). grades GL of purple sweet potato fried 15.40 ± 1.96 were classified as moderate glycemic load (11-19) and steamed purple sweet potato was 21.61 ± 1.96 which is considered a high glycemic load (> 20). value of GL were statistically significantly different at different processing (independent t-test p <0,05). Conclusion : Purple sweet potato fried had a high glycemic index and moderat glycemic load, so it can be consumed by the portion (76 g). While the steamed purple sweet potato had a glycemic index and glycemic load was high, so that can be consumed no more than 65 grams.
