我过去长期主粮黑面馒头，但现在觉得它的GI不低啊，

Is whole wheat bread high GI?

 

 

Whole wheat bread and products labeled “whole grain” are not good choices because they usually are made with pulverized grains (flour) rather than whole or cracked grains. For that reason, most whole wheat bread has the same high GI ranking as white bread – about 70.
