25 Foods That Can Cause Miscarriage in Pregnancy


Pregnancy is a unique time in a woman’s life, characterized by the excitement of nurturing a new life and the concerns surrounding ensuring optimal health. The role of diet during this critical period cannot be overstated, as what a pregnant woman consumes directly impacts her well-being and that of her unborn child. However, some foods may pose risks, potentially increasing the chances of complications, including miscarriage.
