Wonder bread white has 140 calories, 1.5g of fat, 5g of protein, and 29g of carbs for two slices. 5g of claimed added sugar.
In comparison, a recipe I’ve used to make very good white bread (the zojirushi recipe for their bread maker, for reference) has, for an equivalent weight of bread: 137 calories, 2.2g of fat, 3.9g of protein, and 24.8g of carbs. The recipe has roughly 2.5g of “added sugar” per that bread weight.
I wouldn’t consider 4g more of carbs per equivalent weight, or 2.5g more sugar, to be a “lot” more sugar.
