What to know

A note on peanut and tree nut allergies

Peanuts and tree nuts are legally distinct allergen categories under FDA rules, even though they are often grouped together casually. Both are on the FDA's list of nine major food allergens, but avoiding one does not mean you are automatically avoiding the other.

Cross-contact risk still applies. If you are nut-free for allergy reasons, check both the ingredient list and any facility statement even on a bar that does not list peanuts among its ingredients.

If nuts are a flavor preference rather than an allergy concern for you, peanut butter also adds a meaningful amount of fat and calories, worth checking if you are tracking those.

What to check before you buy

Peanuts and tree nuts are legally distinct allergens, so a "peanut-free" claim does not mean tree-nut-free, and vice versa.
Peanut butter adds real fat and calories to a bar, not just flavor, so check those numbers if you are tracking them.
If you or someone you are shopping for has a nut allergy, our nut-free rankings are a safer starting point than this category.

Frequently asked questions

How did you pick these bars?

Every bar was bought at retail and scored 1–10 on four pillars: macro profile, taste and flavor accuracy, texture and mouthfeel, and ingredients and digestibility. The overall score is the straight average. Scores and rankings are never for sale.

What do the score badges mean?

9.0 and above earns Top Pick. 7.5–8.9 is Recommended. 6.0–7.4 gets a Caution, usually a macro or ingredient trade-off worth knowing about. Below 6.0, we tell you to skip it.

Are peanuts considered a tree nut?

No. Peanuts and tree nuts are legally and botanically separate allergen categories, both included among the FDA's nine major food allergens.

Does peanut butter add much fat to a bar?

Yes, a meaningful amount. Peanut butter contributes real fat and calories, not just flavor.

Where should I look if I need to avoid nuts entirely?

Check our nut-free rankings instead, and read the label carefully even there.
