Pregnancy Diet

Focus on These Essential Nutrients

A balanced pregnancy diet means paying special attention to certain nutrients that help both the parent and the growing baby stay healthy. The following sections explain which nutrients are most needed, how much is required, and where to find them in everyday foods.

Folate and Folic Acid

Folate, a type of B vitamin, supports a baby’s early brain and spinal cord growth. Getting enough folate or folic acid before and during pregnancy lowers the chances of neural tube defects and reduces the risk of early birth or low birth weight. Most experts recommend taking 400 micrograms daily before pregnancy and increasing to 600 to 1,000 micrograms during pregnancy.

Sources of Folate and Folic Acid

  • Fortified breakfast cereals
  • Dark leafy greens like spinach
  • Beans, lentils, and peas
  • Citrus fruits such as oranges
  • Asparagus and peanuts
Food SourceServing SizeFolate/Folic Acid (mcg)
Fortified cereal1 cup100–400
Boiled spinach1/2 cup131
Boiled great northern beans1/2 cup90
Boiled asparagus4 spears89
Small orange129
Dry roasted peanuts1 ounce27

People planning pregnancy should take a daily prenatal vitamin that includes folic acid at least a few months before getting pregnant. This fills any nutritional gaps and provides consistent levels needed for early development.

Calcium

Calcium helps build the baby’s bones and teeth and supports proper muscle, nerve, and blood vessel function. Pregnant adults need about 1,000 milligrams daily, while pregnant teens should aim for 1,300 milligrams.

Rich Sources of Calcium

  • Dairy products such as cheese, milk, and yogurt
  • Calcium-fortified juices
  • Leafy greens like broccoli and kale
  • Canned fish with bones, such as salmon
  • Fortified cereals
Food SourceServing SizeCalcium (mg)
Calcium-fortified orange juice1 cup349
Mozzarella cheese (part-skim)1.5 oz333
Skim milk1 cup300
Low-fat yogurt with fruit6 oz258
Canned pink salmon with bones3 oz181
Boiled spinach1/2 cup123

Most people absorb calcium best from dairy. For those who do not consume dairy, fortified juices and cereals, plus certain vegetables, also provide calcium. Spreading calcium-rich foods throughout the day helps with absorption.

Vitamin D

Vitamin D works with calcium to help build baby’s bones and teeth. It also helps the parent’s body absorb calcium. The recommended amount during pregnancy is 600 international units each day.

Main Sources of Vitamin D

  • Fatty fish like salmon
  • Fortified milk and orange juice
  • Eggs
Food SourceServing SizeVitamin D (IU)
Cooked sockeye salmon3 oz570
Skim milk (fortified)1 cup100
Fortified orange juice8 oz100
Hard-boiled egg143.5

It can be difficult to get enough vitamin D from food alone, so fortified foods or short, safe exposure to sunlight can help. Sometimes, a healthcare provider may suggest supplements to ensure adequate intake.

Protein

Protein supports every stage of a baby’s development, including the growth of organs, tissue, and the immune system. During pregnancy, the amount of protein needed increases to about 71 grams daily. Protein can be found in:

  • Lean meats like chicken and beef
  • Fish, such as salmon and tuna
  • Eggs
  • Beans and lentils
  • Nuts, seeds, and soy products
  • Dairy items like cottage cheese and milk
Food SourceServing SizeProtein (g)
Low-fat cottage cheese1 cup28
Grilled chicken breast3 oz26
Canned pink salmon3 oz17
Boiled lentils1/2 cup9
Skim milk1 cup8
Peanut butter2 tbsp7
Hard-boiled egg16

Including a range of protein-rich foods across meals and snacks makes it easier to meet daily needs. Plant-based sources (like beans, nuts, and tofu) are great options, especially for vegetarians.

Iron

The body uses iron to create hemoglobin, which carries oxygen in red blood cells. Iron needs double during pregnancy because of increased blood volume and the demands of the growing baby. The goal is to get 27 milligrams each day.

Iron-Rich Foods

  • Lean red meats, turkey, and chicken
  • Fish
  • Fortified cereals and grains
  • Beans, lentils, and spinach
Food SourceServing SizeIron (mg)
Iron-fortified oats1/2 cup20
Lean beef tenderloin3 oz3
Boiled spinach1/2 cup3
Boiled kidney beans1/2 cup2
Dark turkey meat3 oz1

The body absorbs iron from meat more easily than from plant sources. To boost absorption of iron from plant-based foods, eat them with foods high in vitamin C (like oranges, tomatoes, and strawberries). Calcium can lower the absorption of iron, so avoid taking iron supplements with calcium-rich products at the same time.

Not getting enough iron raises the risk of iron deficiency anemia, which can cause fatigue and, in severe cases, increase the chances of early birth, low birth weight, or postpartum depression.

Supplements

Even with careful meal planning, getting all the nutrients needed during pregnancy from food alone can be difficult. Most people take a daily prenatal vitamin to help cover any gaps, especially for nutrients like folic acid, iron, and sometimes vitamin D and calcium.

People with restricted diets—such as strict vegetarians or those with health problems—may need extra supplements. Some herbal or over-the-counter supplements may not be safe during pregnancy, so always talk to a healthcare provider before taking any supplements, especially herbal products.

Key Supplement Guidelines

  • Most prenatal vitamins include folic acid, iron, and iodine.
  • Extra vitamin D or calcium may be suggested if dietary intake is low.
  • Omega-3 fatty acids, such as DHA, can help with brain development in babies and may be included in some prenatal vitamins.
  • Over-the-counter or herbal supplements should only be taken with approval from a healthcare provider.
Supplement TypeCommon Reason for UseCaution
Prenatal vitaminGeneral support for key vitamins and mineralsSelect product recommended by healthcare provider
Iron supplementPrevent or treat anemiaTake separately from calcium
Calcium supplementBoost intake for those avoiding dairyDo not overload; excess can be harmful
Vitamin D supplementWhen sun exposure and diet are not enoughFollow provider dosing
Omega-3 (DHA)Supports brain and eye developmentCheck source and purity

When choosing any nutritional supplement, follow the advice of your healthcare team. Needs can change throughout pregnancy, so regular check-ins help keep nutrition on track for both parent and baby.
