Is peanut butter gluten-free? Yes, keep the jar crumb-free

Yes. Plain peanut butter is gluten-free: peanuts, sometimes oil, salt and sugar.

What to check

• Flavoured versions: spreads with cookie, biscuit or cereal pieces contain wheat. Read the label.
• The jar at home: a knife that has touched ordinary toast carries crumbs into the jar. Give the coeliac in the house their own jar, or use a squeeze bottle.
• Peanut butter snacks and bars may add wafers or oats; check the ingredients.
