Commercially produced white bread may contain added sugar, ranging from 1-2 grams per slice. This can be bad because it's high in carbs and low in nutrients, and can increase blood sugar and hunger. Look for whole-grain bread instead, which is higher in fiber. You can check the amount of sugar in bread by looking at the nutrition label. Choose bread that has at least 3g of fiber per slice and less than 100 calories per slice. Avoid white bread and bread that doesn't list "whole" as the first ingredient. In general, try to avoid white bread as much as possible.
