Can you eat brazil nuts while pregnant?
SafeYes, Brazil nuts are safe in pregnancy, and the NHS counts unsalted nuts as both a protein food and a good snack. A small handful a day is plenty, since Brazil nuts are unusually concentrated in selenium.
Why
Brazil nuts carry none of the risks that put other foods on the avoid list: there is no Listeria concern as with soft ripened cheese or deli meat, no mercury as with swordfish, and no raw egg or unpasteurized dairy involved. The NHS healthy pregnancy diet guidance puts nuts in the protein group alongside beans, pulses, fish and eggs, and suggests unsalted nuts as one of the better snacks when you are hungry between meals. ACOG likewise treats nuts as a normal source of protein and healthy fat in pregnancy. The one practical note is portion size rather than safety: Brazil nuts are far richer in selenium than any other nut, so a few a day is a sensible habit instead of eating through a whole bag in one sitting.
Safer alternatives
- Unsalted almonds
- Walnut halves
- Pumpkin seeds
- Roasted chickpeas
- Sunflower seed butter on toast

Frequently asked questions
How many Brazil nuts a day is reasonable in pregnancy?
There is no official pregnancy limit, but a few nuts rather than a large handful is the sensible approach because Brazil nuts are extremely selenium-dense. If you also take a prenatal vitamin containing selenium, keep the nuts as an occasional snack rather than an everyday habit.
Will eating nuts in pregnancy give my baby a nut allergy?
No. The NHS is clear that you can eat peanuts and other nuts during pregnancy as part of a healthy diet, unless you are allergic yourself or your own clinician has told you otherwise. Avoiding nuts has not been shown to protect the baby from allergy.
Are salted or chocolate-covered Brazil nuts still fine?
They are safe, they are just less useful. The NHS suggests unsalted nuts as the pregnancy-friendly version, and the chocolate-coated kind sits closer to a dessert, so treat it that way.
