Precedence
“Candy, all white sugar and its products, and white flour, including its products such as macaroni, spaghetti, crackers, etc., should be absolutely barred from the diet of the child. All these are energy-producing foods that contain no building materials for the body. The consequences of their toleration are susceptibility to infections, enlarged tonsils, carious teeth, unruly dispositions, stunted growth, rickets, maldevelopment, and very often permanent damage to many organs of the body (especially the endocrine glands) that depend on the vitamin supply for their normal function and development.”
-Dr. Royal Lee (1938)

carbs are also addictive, it's no accident the first thing they put in to a newborns mouth is sugar water.
