ABSTRACT
Twenty three diabetic subjects from the institute of diabetes [6 F and 6 M] NIDD, [1 F and 10 MIDDM] and 11 normal subjects [6 F and 5 M] as control. All subjects ingested 5 test diets similar in P.F. CHO, and calories. Each contains one source of CHO [Sucrose, rice, potatoes, balady bread and brod bean] and 2 exchanges of whole milk. A standard O.G.T.T, made for all subjects. Blood samples were taken at fasting, 1[st] and 2[nd] hour of ingestion all diets and glucose. GI was estimated for each source of CHO in the 3 groups. Statistical analysis showed that glucose had the highest PG response and bean had the lowest in control group. In NIDD there was no significant difference between all test diets and glucose. In IDDM potatoes had the highest response in PG and bread had the lowest while sucrose, bean and rice had similar responses which is lower than potatoes and higher than bread and glucose. GI estimation agreed well with the statistical analysis of PG values in the 3 groups
