Overview
Peanuts are a nutritious legume often enjoyed as a snack or ingredient in meals. For pregnant women in the US, they provide plant-based protein, healthy fats, and essential nutrients like folate and vitamin E. Recent research indicates that moderate consumption is not only safe but may offer protective benefits against childhood peanut allergies when the mother has no personal allergy history.
Safety Details
According to peer-reviewed studies, including a 2014 analysis in JAMA Pediatrics, maternal peanut intake during pregnancy does not increase allergy risk in offspring and may reduce it by up to 30% with regular consumption. There are no significant risks of listeria, mercury, or toxoplasmosis associated with peanuts. The FDA classifies peanuts as safe for pregnant women without allergies. Risks are minimal unless you have a known peanut allergy, in which case complete avoidance is advised. Portion control is recommended at 1-2 ounces (about 28-56 grams) per serving to manage calorie intake and prevent excessive weight gain.

Second Trimester: Ideal for increased intake as energy needs rise; up to 2 ounces helps meet 71g daily protein goals per ACOG guidelines.
Third Trimester: Continue moderate consumption; peanuts provide sustained energy without spiking blood sugar. Avoid salted varieties to manage sodium levels under 2,300mg daily.
Alternatives/Tips
If concerned about allergies, opt for peanut butter on whole-grain toast or unsalted roasted peanuts. Safe preparation includes choosing pasteurized products and storing in cool, dry places. Alternatives include almonds or sunflower seeds for similar nutrients. Always check labels for cross-contamination if you have sensitivities.
When to Consult Your Doctor
Discuss peanut consumption at your prenatal visits if you have a family history of allergies. Your OB-GYN can provide personalized advice based on blood tests or prior reactions. Immediate medical attention is needed for any signs of allergic reaction such as hives or swelling.
