Eating for the baby's brain in pregnancy

How many eggs can I eat a day while pregnant?

Quick answer

For most healthy pregnant women, eggs are an everyday food, and two a day is a practical target. Each large egg has about 147 mg of choline, roughly a third of the 450 mg you need daily, plus some iodine and vitamin D. Cook them until the yolk and white are firm. You don't need six a day.

Two a day is the sweet spot

One large hard-boiled egg has about 147 mg of choline. That's roughly a third of the 450 mg pregnancy target. Two eggs a day gets you about two-thirds of the way. Add a serving of meat, fish or beans and a glass of milk, and you're there.

Some days three eggs makes sense, if you don't eat much meat or fish. Three large eggs give about 441 mg of choline. What you don't need is the "six eggs a day" plan that sometimes circulates in pregnancy forums. Other foods close the gap without turning breakfast into a chore.

If you have a health condition or a diet plan from your doctor, such as for high cholesterol or diabetes, ask how eggs fit into it. Your own care team knows your numbers.

Why eggs matter for the baby's brain

Choline is one of the brain's building materials. Your baby uses it to build the membranes of new brain cells, to make a chemical messenger involved in memory, and to help switch genes on and off at the right time. It also helps carry DHA, the omega-3 brain fat, to your baby.

Most women don't get enough. In US survey data, only about 8.5% of pregnant women reached the 450 mg target, and most prenatal vitamins have little or no choline. In a 2025 lab test of 47 US prenatals, only 12 even listed it. That's why eggs are such a handy fix: they are cheap, quick and full of the nutrient labels skip. Our page on choline in pregnancy covers the research, including what it does and doesn't show.

An egg brings a few extras too:

NutrientIn 1 large eggDaily pregnancy target
CholineAbout 147 mg450 mg (US)
IodineAbout 31 mcg220 mcg (US); WHO says 250 mcg
Vitamin D (in the yolk)About 44 IU600 IU

The vitamin D sits in the yolk, so eat the whole egg rather than whites alone. And while 31 mcg of iodine helps, it's a small slice of the 220 to 250 mcg target. Keep iodized salt and dairy in your week too; our iodine guide explains why.

A note on expectations. Eggs help you reach a target that most women miss. They aren't a brain-boosting trick. In the small Cornell trials, babies of mothers eating about double the choline target did better on some lab tests, but a 2025 review called the overall evidence "insufficient" to say extra choline improves development. Reaching 450 mg is the sensible, safe goal.

Cook them firm

Raw and runny eggs can carry Salmonella, and pregnancy changes your immune system so some food germs hit harder. The rule is simple: cook eggs until both the yolk and the white are firm.

  • Hard-boiled, scrambled until dry, or baked into a frittata are all good.
  • Skip soft-boiled, sunny-side-up and poached eggs with runny yolks until after the birth.
  • Watch for hidden raw egg: raw cookie dough, homemade eggnog and homemade Caesar dressing. Use pasteurized eggs for any recipe that leaves eggs raw.

Easy ways to eat two a day

The trick is to make eggs the lazy option.

  • Boil six at once. Keep them in the fridge, peeled or not. Grab two on the way out the door.
  • Cold eggs on sick days. A chilled hard-boiled egg has no cooking smell, which helps when nausea makes hot food unbearable. See what to eat with morning sickness.
  • Egg on toast. Use bread made with iodized salt for a small iodine bonus.
  • Shrimp fried rice. Leftover rice, frozen shrimp, frozen peas, two eggs, soy sauce, one pan. Eggs and fish in one dinner.
  • Salmon cakes. Canned salmon, an egg and breadcrumbs, pan-fried until cooked through.
  • Egg salad wrap. Chopped hard-boiled eggs with a little mayo and greens.

Pair eggs with fish nights and you cover a lot of ground: choline from the eggs, DHA from the fish, and some iodine from both. Fish, beans and dairy round out the list.

If you can't eat eggs

Allergic, vegan or just can't stand them? You can still reach the target, it just takes more planning. Good choline sources include beef top round (117 mg per 3 ounces), roasted soybeans (107 mg per half cup), chicken breast (72 mg per 3 ounces), cod (71 mg per 3 ounces), a large baked red potato (57 mg) and a cup of milk (43 mg). A fully plant-based day often lands short of 450 mg, so many vegans may need a supplement. Talk it over with your doctor and bring your prenatal bottle.

And skip liver as a shortcut. It's the richest choline food, but it's very high in vitamin A, and the NHS advises avoiding liver and liver products such as pâté in pregnancy.

Keep the eggs going after birth

The choline target rises to 550 mg a day while breastfeeding, because your baby's brain keeps growing fast after birth. One large egg still gives about 147 mg toward it. A new parent who can boil eggs at 2 a.m. can do anything. And when your baby starts solids, well-cooked egg can be one of the early foods; our page on introducing eggs explains when.

Do this

  • Buy a carton of eggs this week and hard-boil six at a time.
  • Eat two eggs most days, whole, with the yolk cooked firm.
  • Check recipes and homemade sauces for raw egg, and use pasteurized eggs if a recipe leaves them raw.
  • Add one other choline food a day: chicken, beef, cod, soybeans, beans or milk.
  • Ask your doctor how eggs fit if you have a condition or diet plan of your own.

When to ask your doctor

Check with your doctor or midwife first if…

  • You have an egg allergy.
  • Your doctor has given you a specific diet, for example for high cholesterol or diabetes.
  • You're vegan or don't eat eggs and are thinking about a choline supplement.

Call your doctor now if…

  • You have vomiting with a fever or belly pain after eating, or can't keep fluids down for 24 hours.
  • You see blood in your vomit or feel faint when you stand.
  • You have vaginal bleeding, fluid leaking or severe belly pain (call your doctor or 911 now).

People also ask

Is it okay to eat eggs every day while pregnant?

For most healthy pregnant women, yes. Eggs are one of the easiest ways to get choline, which most women fall short on. Cook them until the yolk and white are firm. If you have a health condition or a diet plan from your doctor, ask how eggs fit.

Can I eat runny eggs while pregnant?

It's safest not to. Runny or raw eggs can carry Salmonella. Cook eggs until both the yolk and white are firm, and use pasteurized eggs for any recipe that leaves eggs raw, like homemade eggnog, cookie dough or Caesar dressing.

Do I need six eggs a day for choline?

No. Two large eggs give about 294 mg of choline, roughly two-thirds of the 450 mg target. A serving of chicken, beef, fish or beans plus a glass of milk usually covers the rest. Six a day isn't needed to reach the goal.

Can eggs help when I have morning sickness?

They can be one of the easier foods. A chilled hard-boiled egg has no cooking smell, and cold food tends to smell less. It still brings about 147 mg of choline and some iodine. Boil a batch on a good day so they're ready when you feel rough.

How much choline do you need during pregnancy?The US target for choline in pregnancy is 450 mg a day, rising to 550 mg while breastfeeding (Europe's EFSA says 480 mg in pregnancy). Fewer than 1 in 10 US pregnant women reach it, and most prenatals contain little or none. One large egg has about 147 mg, so two eggs plus a few other foods usually gets you there.What can I eat for my baby's development when I have morning sickness?Eat whatever plain, starchy food you can keep down, and tuck in a few cold brain foods when you can: a chilled hard-boiled egg (choline and iodine), plain Greek yogurt, cold milk or cold roast chicken. Keep taking your prenatal. Ordinary morning sickness doesn't raise the risk to your baby (NHS). Ask your doctor about vitamin B6 if nausea is bad.What should I eat during pregnancy for my baby's brain development?Focus on a handful of brain nutrients: choline from eggs, DHA from 8 to 12 ounces a week of low-mercury fish like salmon and sardines, iodine from dairy and iodized salt, iron from meat, beans and fortified cereal, and folate from greens plus your prenatal's folic acid. You don't need to eat for two. Better food matters more than more food.How can vegetarians get enough choline and DHA during pregnancy?If you eat eggs and dairy, choline is easy: two eggs give about 294 mg of the 450 mg daily target. Vegans can get close with soybeans, beans, quinoa and potatoes but often fall short. For DHA, plant omega-3 converts poorly, so algal oil is the practical source. Ask your provider about both supplements, plus B12, iron and iodine.How much iodine do you need during pregnancy?The World Health Organization recommends 250 mcg of iodine a day in pregnancy and while breastfeeding. The US target is 220 mcg in pregnancy and 290 mcg while breastfeeding. The American Thyroid Association advises a daily supplement with 150 mcg of iodine (as potassium iodide), plus iodized salt at home. Many prenatals contain no iodine, so check your label.When should I introduce eggs and peanuts to my baby?For most babies, around 6 months, as part of their first solid foods. Waiting longer does not protect them. Babies with severe eczema or an egg allergy may start peanut foods as early as 4 to 6 months, but only after your doctor checks them first. Serve egg well cooked and peanut thinned, never whole.
