Can I Eat Nuts and Seeds in Pregnancy? Complete Guide
Yes, nuts and seeds are not just safe in pregnancy — they're one of the easiest ways to get extra protein, fibre and healthy fats into your diet without much effort. If you've been avoiding them because of old allergy advice you remember from years ago, it's worth knowing that guidance has changed.
The allergy advice has changed
For a long time, pregnant women (and new parents) were told to avoid peanuts and other nuts to reduce the risk of their child developing a nut allergy. That advice has since been withdrawn. Current UK guidance is that there's no need to avoid nuts in pregnancy unless you're allergic yourself — eating them doesn't increase your baby's risk of a nut allergy. In fact, some research has pointed the other way, suggesting early and regular exposure may support tolerance later on. If you have a nut allergy, obviously keep avoiding the nuts that affect you, and speak to your GP or midwife if you have any personal or family history of severe allergies that worries you.
Good nuts and seeds to choose
Nuts and seeds pack a lot of nutritional value into a small handful, which is useful when nausea or a small appetite make bigger meals harder to face.
- Almonds — a useful source of calcium, helpful alongside dairy for bone health.
- Walnuts — contain plant-based omega-3 fatty acids, useful for general wellbeing.
- Brazil nuts — very high in selenium; two or three a day is plenty, as too many can mean too much selenium.
- Chia and flaxseeds — good sources of fibre and omega-3, useful if constipation is an issue.
- Pumpkin seeds — contain iron and zinc, both in higher demand during pregnancy.
- Sunflower seeds — a source of vitamin E and healthy fats.
Things to watch for
- Salt content — many shop-bought roasted or flavoured nuts are high in salt. Choose plain, unsalted varieties where you can.
- Added sugar or chocolate coatings — fine occasionally, but they add empty calories if eaten daily.
- Choking or allergy history — if you or your baby's other biological parent have a strong allergy history, mention it to your midwife, though this doesn't usually change advice about your own diet.
- Peanuts specifically — peanuts are legumes, not tree nuts, but the same reassurance applies: they're fine to eat in pregnancy unless you're allergic.
Frequently Asked Questions
Can I eat peanuts and peanut butter when pregnant?
Yes. Peanuts and peanut butter are safe in pregnancy unless you have a peanut allergy yourself. The old advice to avoid peanuts to protect your baby from developing an allergy has been withdrawn by UK health authorities. Choose plain peanut butter without high added sugar or salt where possible.
Do I need to avoid nuts to prevent my baby getting an allergy?
No. There's no evidence that avoiding nuts in pregnancy reduces your baby's chance of developing a nut allergy, and current guidance doesn't recommend avoidance for this reason. The only reason to avoid a particular nut is if you are personally allergic to it.
How many brazil nuts is too many in pregnancy?
Brazil nuts are extremely high in selenium, so it's sensible to limit yourself to two or three a day rather than eating them by the handful. Getting too much selenium from food isn't usually dangerous, but moderation is the simplest approach. Other nuts and seeds don't carry this same limit.
