Healthy nut butter: 3 things to check when you buy

Check three things: only nuts on the label, an oil layer on top is normal (stir it in), and pick light or dark by use. Sugar or palm fat means it isn't pure.

Whether a nut butter is a simple food or a sweet spread is usually revealed by a single glance at the label.

One spoonful makes porridge, yoghurt, dressings or sauces creamy. Nuts provide unsaturated fatty acids, plant protein, fibre and, depending on the type, magnesium or vitamin E. A plain nut butter is the simpler choice compared with sweet spreads and fits into recipes with no added sugar, high-protein recipes or vegan recipes.

1. The golden rule: look at the back

Pure nut butter has exactly one ingredient.

Ingredients: almonds. (Or peanuts, cashews and so on.)
That's it. If you see sugar, palm fat, other oils or flavourings, it's no longer pure nut butter.

Manufacturers stretch it with cheaper fat or sugar, and nut butter turns into a sweet spread. In the US, "peanut butter" may contain up to 10 % seasoning and stabilising ingredients besides peanuts, such as hydrogenated oils, and it often contains sugar and salt as well. A jar labelled "100% peanuts" is usually the pure product.

These additives don't belong in pure nut butter

2. A layer of oil on top is usually a good sign

If there's a layer of clear oil at the top of the jar, the product hasn't gone off.

3. Light or dark? Which is better?

Almond butter and tahini (sesame paste) come in both versions:

Which nut butters are interesting nutritionally

Nutrition: what does the table really tell you?

Nut butter is energy-dense – that's normal for a pure nut product. Read the ingredients list first, then the table: sugar should be very low in a plain nut butter.

ButterProtein per 100 gFibre per 100 gSpecial feature
Peanut butterfairly highmediumoften inexpensive
Dark almond buttermediumfairly highvitamin E, magnesium
Cashew buttermediumfairly lowvery creamy
Walnut butterfairly lowmediumdistinctive taste

The exact values vary by type and manufacturer.

Organic, raw or roasted: does it matter?

Not necessarily. Organic nut butter can also contain sugar or other fats. Roasted tastes stronger, raw milder – what really counts is still the ingredients list.

How to judge texture, colour and smell

Differences in colour and texture between batches and roasts are normal, and so is oil separation. If the nut butter smells rancid, tastes clearly bitter or you can see mould around the edge, don't use it any more.

How to store nut butter

In the fridge, nut butter gets firmer. In a warm kitchen it can still make sense; otherwise a dark cupboard is enough.

How much nut butter makes sense?

A portion of 15 to 30 grams – about 1 to 2 tbsp – is usually plenty. Nut butter isn't a problem, it's just very concentrated. It goes well with oats and blueberries, for example. If you have a nut or peanut allergy, avoid nut butter altogether, and check "may contain" warnings too.

Typical uses in the kitchen

Good things to pair with nut butter

The most common buying mistakes

  1. Reading the front instead of the ingredients list: "fitness", "protein" or "natural" tell you nothing about quality.
  2. Thinking the oil layer is a defect: in pure nut butter it's normal.
  3. Confusing a peanut spread with 100% peanut butter: the names sound similar, but the recipes often aren't.
  4. Underestimating the portion: one heaped spoonful can easily be 30 grams or more.

Price: why good nut butter often costs more

Pure nut butter is made only from nuts, so the price of the raw material feeds straight through. A high price isn't a mark of quality in itself, but a very low price for almond, hazelnut or pistachio butter is a reason to read the label carefully.

FAQ

What should I look for when buying nut butter?

The ingredients list: it should name only nuts. If it lists palm fat, sugar or salt, it's no longer pure nut butter.

What does the layer of oil on nut butter mean?

In pure nut butter it's normal and often points to a product without stabilisers. It doesn't replace a look at the ingredients list, though. Don't pour it off – stir it in well.

What's the difference between peanut butter and 100% peanut butter?

Standard peanut butter often contains peanuts plus sugar, salt and oil. 100% peanut butter is usually made only from ground peanuts and is the simpler choice.

Does nut butter need to go in the fridge?

Not necessarily. A cool, dark cupboard is usually enough; in a warm kitchen the fridge makes sense. The butter gets firmer there.

Is dark or light nut butter better?

It depends on how you use it. Dark butter has a little more fibre and a stronger taste; light butter is milder and more versatile in sauces or desserts.
