I have zero confidence in dietary advice at this point. Bread has been a dietary staple for millennia. There are new studies that show no differences in outcomes in diets that contain bread, contain butter, contain most anything. Dietitians simply parrot whatever is current. We can all find our own way.
And there are outright deceptions. Anyone who has traveled in the Mediterranean area has encountered the centrality of breads to these cultures. I have a number of older cookbooks from these areas, and every single one has a chapter that begins "Bread is the FOUNDATION of the __________ diet" and giving multiple recipes for breads of various sorts, mostly since the 18th century from white wheat flour. Most Med cultures have breads for breakfast, lunch, and dinner, and mostly commercially baked white bread. When I see "Mediterranean Diet" advice that omits bread, I have to laugh.
