Food Safety During Pregnancy

Knowing what to eat is important, but knowing how to eat it safely is crucial. Protect yourself and your baby with these guidelines.

High-Mercury Fish

Why: Can harm baby’s developing nervous system.

E.g., Shark, swordfish, king mackerel, tilefish.

Unpasteurized Dairy & Juices

Why: Risk of Listeria, a harmful bacteria.

E.g., Soft cheeses (Brie, Feta, Camembert) unless labeled "pasteurized".

Raw or Undercooked Meat & Eggs

Why: Risk of Salmonella, E. coli, and Toxoplasmosis.

E.g., Rare steaks, homemade Caesar dressing, raw cookie dough.

Deli Meats & Hot Dogs

Why: Risk of Listeria. Must be heated until steaming hot.

E.g., Cold cuts, paté, refrigerated smoked seafood.

Raw Sprouts

Why: Bacteria can be present inside the seeds.

E.g., Alfalfa, clover, radish, and mung bean sprouts.

Myth Busting

Fact: Moderate caffeine intake (under 200mg/day, about one 12-oz cup) is generally considered safe.

Myth: All sushi is off-limits.

First Trimester

First Trimester Nutrition Guide: Weeks 1 to 13

The first trimester is when most of the foundational development happens. The neural tube closes. The heart begins to beat. Major organ systems form. And most of this happens in the first eight weeks, often before a pregnancy is even confirmed. Nutritionally, the first trimester is less about eating more and more about eating right. Calorie needs don't increase significantly in the first trimester, according to ACOG. What increases is the importance of getting specific nutrients consistently, often at a point when nausea makes eating consistently harder than usual.
