can I eat peanuts?
Peanuts are safe to eat during pregnancy unless you yourself are allergic to them. The old advice to avoid peanuts in pregnancy was withdrawn years ago — eating them does not increase your baby's chance of a peanut allergy.
why it matters
Earlier guidance suggested avoiding peanuts might prevent allergies in children; research showed the opposite may be true, and the advice was formally reversed (UK in 2009). Current evidence suggests normal peanut consumption in pregnancy is fine and possibly protective.
how to have it safely
Enjoy peanuts, peanut butter and peanut-containing dishes as normal. They're a solid source of protein, folate and healthy fats — genuinely useful in pregnancy.
worth knowing
- The only reason to avoid peanuts is your own allergy — pregnancy doesn't create a new one.
- NHS and US guidance agree: no need to avoid peanuts (or other nuts) while pregnant or breastfeeding.
- Some studies suggest eating peanuts in pregnancy may lower the child's allergy risk, though evidence isn't definitive.
- Choose peanut butters without excessive added sugar and salt if it's a daily habit.
common questions
Will eating peanuts while pregnant give my baby a peanut allergy?
No — this old belief has been overturned. Studies found avoidance didn't prevent allergies, and normal consumption may even be mildly protective. The advice to avoid was officially dropped.
Is peanut butter safe during pregnancy?
Yes — it's pasteurised in effect by roasting and processing, and nutritionally useful: protein, folate, niacin and healthy fats. Whole-nut versions with minimal added sugar are the best everyday pick.
