What is actually in it
Peanut butter is the clearest case of a food that is vegan by default and non-vegan only by addition. The base is roasted, ground peanuts, which are legumes, giving roughly 25 g protein per 100 g and a fatty-acid profile dominated by oleic acid. Three additives change the verdict. Honey appears in honey-roast and 'sweet and salty' jars, sometimes far down the list. Fish-derived omega-3 (EPA/DHA) is added to a small number of fortified spreads marketed for heart health, which is easy to miss because the front of the pack says 'omega-3' without naming the source; algal DHA versions exist and are vegan. Vitamin D3 in fortified spreads is usually lanolin-derived from sheep wool unless it states D3 (lichen) or D2. Chocolate, cheesecake and dessert-flavour jars often carry milk solids or whey. Everything else you will see — palm oil, mono- and diglycerides, icing sugar, molasses — is plant-derived in practice, though mono- and diglycerides can theoretically come from animal fat, which is why some brands add a 'from vegetable sources' note.

- Usually plant, occasionally animal fat
- D3 (cholecalciferol) — Vitamin D3
- Lanolin unless lichen-sourced

- Animal (bee)
Questions people ask
Is palm oil in peanut butter vegan?
Technically yes — it is a plant fat used to stop separation — though many people avoid it for deforestation reasons.
Does natural peanut butter go rancid faster?
Natural peanut butter separates normally, but its oils can also become rancid. Stir it, follow the storage instructions and refrigerate after opening if recommended.
Is powdered peanut butter vegan?
Yes in the plain versions — it is defatted peanut flour with a little salt and sugar. Chocolate powdered versions can contain milk.
Which peanut butter has the best protein?
The 100%-peanut jars, because nothing dilutes the peanut content. Two tablespoons give about 7-8 g of protein.
Is peanut butter healthy on a plant-based diet?
It is a useful source of protein, monounsaturated fat, vitamin E and magnesium. Choose unsweetened jars and treat it as a calorie-dense food rather than a free extra.
