Questions
Are fruit and nut bars healthier than granola bars?
They usually have fewer, less processed ingredients and no added sugar, but their total sugar and calories can be similar or higher because of dates.
Fruit & Nut Bars
Fruit and nut bars are the parent decision: start with Larabar for a whole-food, no-added-sugar option, or choose RXBAR if you also want protein.
Whole Grain Bars
Whole grain bars follow the granola-bar logic under this parent: make sure a whole grain is the first ingredient and compare added sugar per bar.
