1. Smoked & Refrigerated Seafood

Smoked and refrigerated seafood labeled lox, jerky, nova style, and kippered are best avoided during pregnancy. They contain a bacteria called Listeria monocytogenes that causes listeriosis, a condition responsible for symptoms such as vomiting and diarrhea. It could cause illnesses in newborns, or even induce a miscarriage or stillbirth.

What’s more is that processed seafood contains large amounts of salt, which might lead to an increase in blood pressure or swelling of the body parts in pregnant women.
