Core pregnancy nutrition goals

1. Take a prenatal vitamin
A prenatal vitamin is usually recommended because pregnancy increases the need for nutrients like folic acid, iron, calcium, vitamin D, choline, omega-3s, B vitamins, and vitamin C. ACOG says these nutrients support both the pregnant person and the fetus, and food should still be the main source.

2. Get enough folic acid
Folic acid helps reduce the risk of neural tube defects. The CDC recommends 400 mcg of folic acid daily, ideally starting at least 1 month before pregnancy and continuing during pregnancy.

3. Prioritize iron-rich foods
Pregnancy increases iron needs because blood volume rises and the baby and placenta need iron. Iron foods include lean meat, poultry, fish, eggs, beans, lentils, spinach, tofu, and fortified cereal. Pair plant iron with vitamin C foods like oranges, berries, tomatoes, or peppers.

4. Eat protein at each meal
Good choices include eggs, Greek yogurt, chicken, fish, beans, lentils, tofu, nuts, and lean meats. Protein helps fetal growth and keeps blood sugar more stable.

5. Choose smart carbohydrates
Focus on oatmeal, brown rice, potatoes, sweet potatoes, fruit, beans, and whole grains. These give energy and fiber, which can help with constipation.

6. Include healthy fats
Avocado, olive oil, nuts, seeds, eggs, and low-mercury fish support brain and nervous system development.

Fish: yes, but choose wisely

Pregnant or breastfeeding people are advised to eat 8–12 ounces per week of seafood from lower-mercury choices. Good options often include salmon, sardines, trout, anchovies, cod, tilapia, and shrimp. Avoid high-mercury fish such as shark, swordfish, king mackerel, and bigeye tuna.

Foods to avoid or handle carefully

Pregnancy raises the risk from certain foodborne germs, including Listeria. The CDC recommends avoiding or being cautious with foods such as undercooked meat or eggs, unpasteurized milk or cheese, and unwashed produce.

Also avoid:

Alcohol: The CDC says there is no safe time for alcohol use during pregnancy.
Raw or undercooked seafood, meat, and eggs
Unpasteurized dairy or juice
High-mercury fish
Excess caffeine — many clinicians suggest staying around 200 mg/day or less, but confirm with the OB.

Simple pregnancy plate

A strong meal could look like:

½ plate vegetables or fruit
¼ plate protein
¼ plate whole grain or starchy vegetable
Add healthy fat
Drink water

Example: salmon, sweet potato, spinach salad with olive oil, and berries.

When to ask the doctor

Consult the OB/midwife about prenatal vitamins, iron, vitamin D, nausea, constipation, gestational diabetes risk, high blood pressure, food cravings, or any supplement. Do not add high-dose vitamins, herbs, or iron unless the pregnancy provider approves it.

A simple rule: food first, prenatal vitamin daily, hydrate well, avoid alcohol, choose low-mercury fish, and be careful with food safety.
