Common questions
What should I look for in a kids' granola bar?
Low added sugar (≤3g), at least 2g protein or 3g fiber, recognizable ingredients, and no artificial dyes. Avoid bars where sugar (or a sugar synonym) is in the first three ingredients.
Are granola bars with honey okay?
Honey counts as added sugar. A bar with 3g added sugar from honey is still Tier C - it depends on the total, not the source.
What about nut butter bars?
Nut butter adds protein and healthy fat - great for after school. Just check the sugar: some nut-butter bars have added chocolate or honey that pushes them to Tier D/E.
Are these safe for nut-free schools?
Some are, some aren't. Filter by "Nut-Free" on the category page, or check the allergen section on each product page.
How do I read the ingredient list?
Ingredients are listed by weight, highest first. If sugar (or brown rice syrup, cane juice, etc.) is in the top 3, the bar is likely Tier D or E even if the label says "natural."
