Dont think i've ever eaten potato bread, i might just look at the ingredients to be sure there arent weird ingredients in it.

There's a few preservatives and corn syrup. But less than 2% of a bunch of other stuff, including soybean oil. It's mostly unbleached flour, milk and water. Those are all first in the list.
I dont eat lots of bread, but try to eat homemade sourdough when i do. Or i've found that homemade corn tortillas are a great sub for when i crave "bread". King Arthur Flour makes a great organic masa for making them.
When the kids are a little older, I'll get into making our own bread. I have a bread maker on my wish list 😉
You should try it. It's delicious.
