> White bread is the "100" on the GI scale, and cola is 60 It depends on methodology how you calculate it. For example this article says that per some methodology cola GI can be 91: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1989668/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1989668/ Also, I think GI is weight normalized, so you compare 250g of cola with 40g of carbs to 250g of white bread with 120g of carbs.
