Why are peanuts safe in pregnancy?
The NHS is clear: peanuts are safe in pregnancy unless you yourself are allergic. Older advice about avoiding peanuts to prevent allergies has been withdrawn — there's no evidence that eating peanuts while pregnant affects your baby's chances of a peanut allergy.
You can also check the calorie content of peanuts alongside their safety information. Also check medication safety during pregnancy if you're managing any conditions.
