Diabetes affects at least 285 million people globally, and this number continues to increase. Clinical complications include impaired glucose metabolism, hyperglycemia, dyslipidemia, atherosclerosis non-alcoholic fatty liver disease. Evidence has shown that natural phenolics play a protective effect on both the development management of type 2 diabetes. This study evaluated effects extract from peanut skins containing polyphenols induced- hyperglycemia using in vivo vitro methods. A human...

Sweet potatoes are rich in dietary fiber, minerals, vitamins and bioactive compounds such as β‐carotene, phenolics anthocyanins that provide distinctive skin flesh colors. Although high carbohydrate, sweet usually have moderate (56–69) glycemic index (GI). This study aimed to 1) investigate GI of different commercial cultivars potatoes; 2) determine how the is impacted by specific plant components. Eight potato with white, yellow, orange, or purple were analyzed for moisture, ash, fat,...

The objective was to compare the glycemic response among Beauregard orange sweet potato (SP), Pakistan White Star SP, commercial Caiapo (a dietary supplement from Japanese SP), and skin. Cultivars had similar proximate analyses. Skin higher in protein, fiber, ash lower NFE than whole SP. Healthy diabetic volunteers (20 each) were fed 50 g of carbohydrate Glucose, Star, Skin, Beauregard, on alternate mornings. Rise blood glucose (BG) 0–1 h significantly greater for SP all subjects.
