Brussels sprouts are a rich source of iron and folate, making them a good choice for pregnant women. Brussels sprouts even reduce the chances of delivering a premature baby. Moreover, Brussels sprouts are also known to lower the risk of low birth weight in babies and prevent birth defects such as spina bifida. But, being a type of sprout, Brussels sprouts may have bacteria in them, and should therefore not be consumed raw. It is best to eat Brussels sprouts after they are thoroughly cooked.
