The fundamental principles of healthy eating remain unchanged during pregnancy: aim to consume plenty of fruits, vegetables, whole grains, lean proteins, and healthy fats. However, certain nutrients play a particularly vital role during this time. Here’s a closer look at the key nutrients to prioritize for a healthy diet in pregnancy: iron, calcium, and folate.

Folate and Folic Acid: Prevent Brain and Spinal Cord Birth Problems

Folate, a type of B vitamin, helps prevent severe neural tube defects in the developing brain and spinal cord. The synthetic form of folate, known as folic acid, is commonly found in supplements and fortified foods. Research has shown that taking folic acid can reduce the risk of premature birth and low birth weight.

Daily Requirement:
- Before conception: 400 micrograms (mcg)
- During pregnancy: 600–1,000 mcg
Good Sources of vitamins and minerals include a variety of healthy foods.
Folic acid is abundant in fortified cereals, while naturally occurring folate can be found in dark leafy greens, citrus fruits, beans, peas, and lentils.

Examples of Folate-Rich Foods:

Fortified cereal is a great option for breakfast, as it often contains added iron and other nutrients needed during pregnancy. 3/4 cup (15–60 g) = 100–700 mcg
Spinach (boiled): 1/2 cup (95 g) = 131 mcg
Great Northern beans (boiled): 1/2 cup (89 g) = 90 mcg
Asparagus (boiled): 4 spears (60 g) = 89 mcg
Orange (small): 1 (96 g) = 29 mcg
Peanuts (dry roasted): 1 ounce (28 g) = 27 mcg

Taking a prenatal vitamin daily is highly recommended—ideally starting at least three months before conception—to ensure you’re getting enough folic acid. Women who might become pregnant should include this essential nutrient in their daily regimen.

Calcium: Strengthen Bones

Calcium is essential for building strong bones and teeth for both you and your baby. It also plays a critical role in the proper functioning of the circulatory, muscular, and nervous systems.

Daily Requirement:
- Pregnant adults: 1,000 milligrams (mg)
- Pregnant teenagers: 1,300 mg
Good Sources of iron-rich foods that are high in nutrients essential for a healthy diet in pregnancy include leafy greens and legumes.
Dairy products are among the best sources of calcium, but non-dairy options like broccoli and kale are also beneficial. Additionally, many fruit juices and breakfast cereals are fortified with calcium.

Examples of Calcium-Rich Foods:

Fortified cereal: 1 cup (20–60 g) = 100–1,000 mg of vitamins and minerals that are crucial for your baby.
Fortified orange juice is a healthy food option that can help your baby during pregnancy. 1 cup (237 mL) = 349 mg of healthy food options that support your pregnancy.
Mozzarella cheese (part-skim): 1.5 oz. (43 g) = 333 mg
Skim milk: 1 cup (237 mL) = 299 mg of calcium, which is important for a healthy diet in pregnancy.
Low-fat yogurt (fruit-flavored, sweetened): 6 oz. (170 g) = 258 mg
Canned pink salmon (with bones): 3 oz. (85 g) = 181 mg
Spinach (boiled): 1/2 cup (95 g) = 123 mg

Vitamin D: Promote Bone Strength

Vitamin D works alongside calcium to help build strong bones and teeth for your baby.

Daily Requirement: 600 international units (IU)
Good Sources:
Fatty fish such as salmon is an excellent source of vitamin D, which is a vital part of a healthy diet. Other sources include fortified milk and orange juice.

Examples of Vitamin D-Rich Foods include options that you should eat during pregnancy for optimal health.

Sockeye salmon (cooked): 3 oz. (85 g) = 570 IU, contributing to the vitamins and minerals needed for a healthy diet.
Fortified skim milk: 1 cup (237 mL) = 115 IU
Fortified orange juice: 8 oz. (237 mL) = 100 IU
Hard-boiled egg: 1 large (50 g) = 44 IU

Protein: Promote Growth

Protein is essential for your baby’s growth and development throughout pregnancy, particularly in the first trimester. It plays a crucial role in building tissues and ensuring proper function for both mother and baby.

Daily Requirement: 71 grams (g) of dairy foods can provide essential nutrients during pregnancy.
Good Sources:
Lean meats, poultry, seafood, and eggs are excellent sources of protein that should be included in foods to eat during pregnancy. Vegetarian options include beans, peas, nuts, seeds, and soy products.

Examples of Protein-Rich Foods:

Cottage cheese (low-fat, 1% milk): 1 cup (226 g) = 28 g
Chicken breast (grilled, boneless, skinless): 3 oz. (86 g) = 26 g of nutrients that are important to make sure you get during pregnancy.
Canned pink salmon (with bones): 3 oz. (85 g) = 17 g
Lentils (boiled): 1/2 cup (99 g) = 9 g
Skim milk: 1 cup (237 mL) = 8 g of healthy food that can contribute to a balanced diet.
Peanut butter: 2 tbsp (32 g) = 7 g
Hard-boiled egg: 1 large (50 g) = 6 g

Iron: Prevent Iron Deficiency Anemia

Iron is crucial during pregnancy as your body requires double the amount compared to when you’re not pregnant. This mineral is used to make hemoglobin, a protein in red blood cells that transports oxygen to your tissues and your baby, ensuring a healthy food group intake.

Insufficient iron intake can lead to iron deficiency anemia, which may cause fatigue, headaches, and other complications. Severe anemia increases the risk of premature birth, low birth weight, and postpartum depression.

Daily Requirement: 27 milligrams (mg)
Good Sources:
Lean red meat, poultry, and fish are excellent sources of iron. Plant-based options include iron-fortified cereals, beans, and vegetables, which are important foods to avoid deficiencies in vitamins and minerals.

Examples of Iron-Rich Foods:

Fortified quick oats: 1/2 cup (40 g) = 20 mg
Lean beef tenderloin (roasted): 3 oz. (85 g) = 3 mg
Spinach (boiled): 1/2 cup (90 g) = 3 mg
Kidney beans (boiled): 1/2 cup (88.5 g) = 2 mg
Dark turkey meat (roasted): 3 oz. (85 g) = 1 mg of iron, a vital mineral to help your baby grow.

Prenatal vitamins typically include iron, but your healthcare provider might suggest an additional supplement if needed. Iron from animal products is the most easily absorbed by the body. To enhance iron absorption from plant-based sources or supplements, pair them with foods or drinks high in vitamin C, such as orange juice, tomato juice, or strawberries.

Important Tip:
Avoid calcium-fortified orange juice or calcium-rich foods when taking iron supplements, as calcium can inhibit iron absorption.

Supplements: Ask Your Health Care Provider

Even with a well-balanced diet, it can be challenging to get all the nutrients you and your baby need. A daily prenatal vitamin can help fill nutritional gaps, and ideally, it should be taken at least three months before conception.

Your healthcare provider might recommend specific supplements if you:

Follow a strict vegetarian or vegan diet
Have a chronic health condition
Are at risk of certain deficiencies

Important Consideration:
Before taking any herbal supplements during pregnancy, consult your healthcare provider. Some herbal products can pose risks to you or your baby and should be avoided.
