|概要||GI (glycemic index) is used to show the potency of foods to increase blood glucose. No research has been carried out about gender and age differences of GI of foods of distinct structures such as glucose and sucrose. We wanted to know if there is a big difference in GI depending upon sex and age to take foods.
We gave 50 gm of either glucose or sucrose in a cross over study to three groups of healthy old (n=44, mean age: 62.4 ± 9.6), young men (n=36, mean age: 20.6 ± 1.6) and women (n= 35, mean age: 21.2 ± 0.7).
when GI of young men who took, glucose was set 100, GI of old men was 156. GI of young females who took sucrose was 55 When blood insulin levels of young men were set 100, insulin levels of old men who took sucrose were 30.
GI of glucose of old men were 156% compared to GI of young men. GI of young females who took sucrose was 55% of GI of young men who took glucose. These results indicate that GIs were different between old and young men and young females even if they took the same foods with distinct structure such as glucose and sucrose.
