Yes, noodles—including rice noodles—are generally safe to eat during pregnancy. They are a good source of complex carbohydrates, which can fight constipation, proteins which aid in fetal tissue and brain growth, and healthy fats which provide satiety and boost absorption of fat-soluble vitamins.
Women with gestational diabetes should consider the carbohydrate content of the noodle bowls and factor the specific grams of carbohydrates into their daily allowances. Note that some bowls contain allergens such as nuts and seeds. Always read nutrition labels to ensure that all ingredients comply with your individual dietary needs.
