People have strong opinions about whether bread crusts are worth eating. I was surprised to learn that people have been questioning the value of bread crusts for a long time. Here’s a question and response that I found in a hundred-year-old magazine:
Is the Crust of Bread Less Digestible than the Inside?
No! The crust is satisfactorily digested when properly chewed. Part of the protein of the crust is present in a more soluble form and some of the starch has been partly digested to dextrin through the action of the heat in baking. The crust is fully as nutritious as the crumb or the inside of the loaf.
