Walnuts are a nutrient-rich tree nut offering plant-based omega-3 fats, protein, and magnesium. Their satisfying crunch makes them an easy addition to snacks and meals throughout pregnancy.
Why it's good in pregnancy
Walnuts are one of the richest plant sources of omega-3 fatty acids, which support your baby's brain and eye development. Their protein and magnesium content help support tissue growth and muscle function, while fiber and zinc round out their nutritional value. Eating walnuts regularly, unless you have a nut allergy, can be a simple way to boost healthy fat intake.

Safety
Store walnuts in an airtight container in a cool, dry place, or refrigerate them to prevent the oils from turning rancid. Choose plain, unsalted varieties when possible to keep sodium intake in check. If you or a family member has a tree nut allergy, discuss walnut consumption with your healthcare provider first. Wash your hands and any shared surfaces after handling nuts if allergies are a concern in your household.
