I love adding pine nuts to my salad for that extra crunch. Can I continue having them during pregnancy? Yes. According to a post published in the Centre for Health, Human Rights and Development (CEHURD), pine nuts are a good source of Omega-3 fatty acid, and other healthy fats that help with brain development. These flavorful nuts are a good addition to your pregnancy diet. And, you can have them directly or add them to a dessert, condiment or salad.
