Nutrition labels for nut & seed butters
Nut butter is an allergen-forward product by definition — the main ingredient is the allergen — so the declaration is non-negotiable. Beyond that, the label turns on a 2 tablespoon serving, honest added-sugar handling, and the fat numbers that make or break a 'healthy fats' pitch.
key takeaways
- Nut butters use a 2 tbsp (~32 g) serving — calorie- and fat-dense, so ~180–210 cal is normal.
- The allergen is the main ingredient — name the specific nut in a Contains line; it's mandatory.
- Tahini and other seed butters declare sesame, a required allergen since 2023.
- A voluntary 'may contain' advisory is standard when multiple nuts share equipment.
- 'No added sugar' is a legitimate claim for unsweetened butters; protein claims usually qualify.

The short version
A jar of nut butter is one of the more straightforward things to label and one of the highest-stakes for allergens: the product IS peanuts or tree nuts, so the Contains line is mandatory and prominent. The rest of the panel is about the 2 tablespoon serving and being honest about added sugar and fat — the two numbers health-conscious buyers scan.
Serving size — the part people get wrong
Reference amount: 2 tbsp (about 32 g) for nut and seed butters. The reference amount for peanut butter, almond butter, tahini and similar spreads is 2 tablespoons (roughly 32 g). It's a calorie- and fat-dense serving, so your per-serving calories will look high (180–210 is normal) — that's correct for a concentrated nut product, not a red flag.
Allergens you have to declare
This is the whole point: the primary ingredient is a Big-9 allergen. Peanut butter declares peanuts; almond, cashew and other tree-nut butters declare the specific nut. Watch cross-contact if you run multiple nuts on shared equipment — a 'may contain' advisory is voluntary but common and expected. Seed butters (sunflower, tahini/sesame) matter too: sesame is now a required allergen, so tahini declares sesame.
The Nutrillius generator auto-detects the Big-9 allergens from your ingredient list and writes the Contains statement for you — useful even if you only need the ingredient list.
Claims you can (and can’t) make
Every nutrient-content claim on the package has a legal threshold the panel must back up. For nut & seed butters, the ones that come up most:
- Good source of protein — protein ≥ 5 g per serving — most nut butters qualify at 2 tbsp.
- No added sugar — requires no sweetener added; natural (unsweetened) nut butter qualifies.
- No palm oil / no stir — descriptive, must be literally true across the ingredient list.
- Good source of fiber — fiber ≥ 2.8 g per serving — some almond and seed butters reach it.
The builder shows which claims your recipe already qualifies for as you tweak it — see the rounding rules for how the declared numbers behind those thresholds are set.
A sample nut & seed butters label
Unsweetened Almond Butter
INGREDIENTS: Dry-roasted almonds, sea salt.
Contains: Almonds (tree nut).
Serving size 2 tbsp (32g)
Two ingredients, one unavoidable allergen. At 2 tbsp this posts ~190 calories and ~17 g fat — high, and completely normal for a nut butter. No added sugar, so it can carry that claim.
Where nut & seed butters makers slip up
The allergen is the product — declare the specific nut
'Contains: Tree Nuts' isn't specific enough — you must name the actual nut ('almonds,' 'cashews'). And if you process multiple nuts on shared equipment, a voluntary 'may contain peanuts/other tree nuts' advisory is standard; nut-allergic buyers rely on it. This is the label element with the most direct safety consequence.
High fat and calories are correct — don't fight the panel
At 2 tbsp, nut butter posts high calories and fat because it's concentrated nut. That's the honest serving. Don't shrink the serving to 1 tbsp to make the numbers look smaller — the RACC is 2 tbsp, and the 'healthy fats' story is better told with the mono/polyunsaturated breakdown than by hiding the total.

Frequently asked questions
What serving size does peanut butter use?
Two tablespoons (about 32 grams) — the FDA reference amount for nut and seed butters. It's a dense serving, so expect ~180–210 calories and 15–18 g of fat per serving. That's correct for a concentrated nut product, not a labeling error.
How do I declare allergens on nut butter?
Name the specific nut — 'Contains: Peanuts' or 'Contains: Almonds (tree nut)' — not just 'tree nuts.' If you process several nuts on shared equipment, add a voluntary 'may contain' advisory. For tahini and sesame-based butters, declare sesame, which became a required allergen in 2023.
Why is my nut butter so high in calories and fat?
Because it's concentrated nut, and the serving is 2 tablespoons. High calories and fat are expected and honest here. Rather than shrink the serving, tell the 'healthy fats' story with the unsaturated fat breakdown — the total is supposed to look like that.
Can I say my nut butter has 'no added sugar'?
Yes, if no sweetener is added. Unsweetened, just-nuts-and-salt butters carry the claim legitimately. Note that 'no added sugar' says nothing about the small amount of naturally occurring sugar in the nuts — Total Sugars still appears on the panel.
