Glycaemic index of different coconut (Cocos nucifera)-flour products in normal and diabetic subjects

The glycaemic index (GI) of commonly consumed bakery products supplemented with increasing levels of coconut (Cocos nucifera) flour was determined in ten normal and ten diabetic subjects.

description The glycaemic index (GI) of commonly consumed bakery products supplemented with increasing levels of coconut (Cocos nucifera) flour was determined in ten normal and ten diabetic subjects. Using a randomized crossover design, the control and test foods were fed in random order on separate occasions after an overnight fast. Blood samples were collected through finger prick before and after feeding and were analysed for glucose levels using a clinical chemistry analyser. The significantly low-GI (< 60) foods investigated were: macaroons (GI 45·7 (sem 3·0)) and carrot cake (GI 51·8 (sem 3·3)), with 200–250 g coconut flour/kg (P

The test foods with 150 g coconut flour/kg had GI ranging from 61·3 to 71·4.
