When do you ever eat a piece of bread without something that contains fat?
That fat will suppress any sorta of
'OMGosh white bread!' insulin response.
In regards to my comment, I didnt mean to offend, its just that is how myths start, word of mouth, incorrect statements. I can sense you already knew they were speaking rubbish but I thought I would bold that statement
The word you used about Brown/Wholemeal (marketed) that clearly sums up why people believe it to be healthier, and thus that is why so much BS. Difference in White/Brown would be your Minerals/Vitamins. Insulin/GI index well, if you want to go there, here a good article for the GI
GI gives us clues to the behavior of certain foods, but that's exactly the main point of this article. Clues; mere hints are all we get from our current knowledge of GI. Successful application of GI is most consistent when we use higher GI sources to enhance the speed of postworkout glycogenesis, and that's about it. Carb foods are better judged on the basis of degree processing, refinement, or alteration/removal of micronutrition -- NOT on the basis of GI, or even GL. This is as good a time as any to crush the folly of what I call "food discrimination". A prime example of this is cutting out potatoes on the basis of GI. This happens all the time, & the dieter takes pride in thinking he/she is being prudent. Well, the critical thing to realize here is that all food species in nature have unique nutrient profiles. Therefore, unique nutritional benefit can be derived from each species. The natural matrix of plant &/or animal tissue cannot be duplicated in the lab, & hence there are many unidentified beneficial agents in, say, the humble potato. As a matter of trivia, it surpasses bananas in potassium & vitamin C concentration. Not to mention, it provides default hydration, and of course is a great whole-food source of starch. The list goes on & on.
Satiety, micronutrient density, insulin response, & surrounding factors altering glucose kinetics are all much like a roll of the dice in terms of bottom-line certainty & reliability of GI. Like all things in science - especially the deep bubbly cauldron that is applied nutritional science - it ain't all that simple. All avenues in this area are winding & complex.

If you can't explain it simply, then you don't understand it well enough.
