Purpose of the Study
The study determined the effects of sweet potato green leaves (lpomea Batatas) on the glycemic responses of diabetics through quasi experimental trial among twenty­three subjects with diabetes mellitus type 2.

METHODOLOGY | Back

Protocol of the study was reviewed and approved by the Ethics Review Board of San Pedro Hospital Incorporated, Davao City. Demographic and dietary profiles were determined through interview and 7-day food record. Subjects were asked not to take their medications and supplements and fast for 8-10 hours the night before the blood extraction. Blood glucose response at 0,30, 60, 90 and 120 minutes after consumption of 50 grams available carbohydrates from the test meals: (Tl- white bread, T2- white bread and sweet potato greer. leaves,T3 - white rice and T4 - white rice and sweet potato green leaves) were obtained through venipuncture. Seven days wash-out period was done after ea.ch test meal. Data were analyzed using descriptive statistics, and independent t-test to check the differences of glycemlc responses.

RESULTS | Back

Mean fasting blood sugar level of the respondents was 7.68 mmol/L, but peak rise of blood glucose happened 60 minutes after consumption of all 4 Test meals. Test meal 1 and 2 exhibited glycemic response shortly after 30 minutes, however the mean glycemic response in test meal 1 was higher (228.76 mg/dL) compared to test meal 2 (192.20 mg/dL) with a mean difference of 34.49 (t=3.93), hence highly significant (p<.01). There was an increase in blood glucose 30 minutes after ingestion of test meal 3 and test meal 4 but, the peak rise happened after 60 minutes is highly significant (p<.05). Glycemic indices of white bread and white rice with sweet potato green leaves both containing SO grams available carbohydrates were 74.47 and 71.68, respectively.

CONCLUSION: | Back

The GI of white bread and white rice alone were significantly higher {p<.05) compared to white bread and potato leaves (Gl=74.47) and white rice with potato leaves (Gl=71.68).
