Even homemade whole-grain bread, while delicious and healthy in its way, has too many non-fiber carbs when you’re trying to minimize them. And my body is unfortunately very efficient at converting the starches to blood sugar. As for bakery whole-grain bread, (and of course the supermarket kind) the ingredients almost inevitably include “wheat flour” which is white flour, not necessarily bleached but minus the bran. This is because bread that is not only “made with 100% whole wheat” (which just means it contains SOME 100%-whole-wheat flour!) but is made with ONLY whole wheat flour (plus any other whole grains) doesn’t rise very well. I’ve struggled with it myself and made some bricks, despite being able to bake gorgeous loaves when allowed to include some unbleached bread flour in the mix. Go ahead, ask your baker. And then enjoy the bread, it’s still great for most people.
