Can You Eat Nuts During Pregnancy?
Nutritional powerhouses with healthy fats, protein, and folic acid — how much is right for you.
Nuts are an excellent pregnancy food, rich in healthy fats, protein, fiber, folate, and minerals. ACOG and NHS recommend including nuts in the pregnancy diet. A daily portion of about 30 g (a small handful) provides optimal benefits. There is no evidence that eating nuts during pregnancy increases the child's allergy risk — in fact, recent research suggests the opposite.
🥜 Why Nuts Are Great During Pregnancy
Nuts are among the most nutrient-dense foods you can eat during pregnancy. A daily handful provides:
- Healthy fats (omega-3 and omega-6): Essential for fetal brain development. Walnuts are particularly rich in ALA omega-3.
- Folate: Almonds and peanuts are good sources of folate, critical for preventing neural tube defects.
- Protein: 5–7 g per 30 g serving — important for tissue growth.
- Iron: Cashews and pistachios provide non-heme iron, helping prevent anemia.
- Magnesium: Helps reduce leg cramps, supports muscle relaxation and sleep.
- Fiber: Aids digestion and helps prevent pregnancy constipation.

🔬 Nuts and Allergy: Latest Research
In the past, pregnant women were sometimes advised to avoid peanuts and tree nuts to prevent allergies in their children. This advice has been reversed.
- A 2014 study in JAMA Pediatrics found that mothers who ate nuts during pregnancy had children with lower rates of nut allergies.
- The American Academy of Pediatrics (AAP) no longer recommends avoiding allergenic foods during pregnancy.
- Current NHS guidance states that there is no reason to avoid nuts during pregnancy unless you yourself are allergic.
Exception: If you have a diagnosed nut allergy, obviously continue to avoid that specific nut and consult your allergist.
📋 Tips for Including Nuts in Your Pregnancy Diet
- Choose raw or dry-roasted nuts without added salt, sugar, or oils.
- Add chopped nuts to yogurt, oatmeal, salads, or smoothies.
- Keep a small bag of mixed nuts as a convenient, portable snack.
- Nut butters (almond, peanut, cashew) are equally nutritious — choose varieties without added sugar.
- Be mindful of portions — nuts are calorie-dense. Stick to about 30 g/day.
- Brazil nuts: Limit to 1–3 per day due to very high selenium content (excess can be harmful).
