As with all sugars, all starches, including all grain products, will spike your blood sugar level. It doesn’t matter if bread is white, whole grain, sprouted, etc. Bread is bread, unless it’s keto bread made out of almond flour, coconut flour, or some other low-carb ingredient.
Ezekiel bread, for example, might be healthier in other ways such as nutrient profile, although the nutrient-density is rather meager compared to many other plant foods and animal foods. For certain, it is not healthy if you’re diabetic, pre-diabetic, or insulin resistant (the majority of Americans fall into one of these categories).
I used to eat Ezekiel bread thinking it was healthier. And this was during the time I was gaining weight and probably developing pre-diabetes or at least worsening insulin resistance. Claims of lower glycemic index is mostly bunk, as the following video shows — and the same would apply to glycemic load as well. The net carbs, excluding fiber, are identical in Ezekiel bread and white bread.
