Glycemic index of frozen and toasted bread

Yes there is similar data on bread like rice that the GI index is lower as compared to fresh bread but studies in human are small with 15-30 people and BG drop is modest : the BG rise decreases from 132-120 so not a huge change. Also there is confusion whether it happens in store bought bread where there are more chemicals . Home made bread has more chances . So in summary there is a small decrease but I would recommend eating healthier version of fresh bread like seeded bread. , 647 bread which has more fiber and less carb. Hope that helps.
