Things you can and cant eat when pregnant

11 Foods and Beverages to Avoid During Pregnancy

One of the first things people learn when they’re pregnant is what they can’t eat. It can be a real bummer if you’re a big sushi, coffee, or rare steak fan.

Thankfully, there’s more you can eat than what you can’t. You just have to learn how to navigate the waters (the low mercury waters, that is). You’ll want to pay close attention to what you eat and drink to stay healthy .

Certain foods should only be consumed rarely, while others should be avoided completely. Here are 11 foods and beverages to avoid or minimize while pregnant.

Mercury is a highly toxic element. It has no known safe level of exposure and is most commonly found in polluted water.

In higher amounts, it can be toxic to your nervous system, immune system, and kidneys. It may also cause serious developmental problems in children, with adverse effects even in lower amounts.

Since it’s found in polluted seas, large marine fish can accumulate high amounts of mercury. Therefore, it’s best to avoid high mercury fish while pregnant and breastfeeding.

High-mercury fish you want to avoid include:

• shark
• swordfish
• king mackerel
• tuna (especially bigeye tuna)
• marlin
• tilefish from the Gulf of Mexico
• orange roughy

However, it’s important to note that not all fish are high in mercury — just certain types.

Consuming low mercury fish during pregnancy is very healthy, and these fish can be eaten up to three times per week, according to the Food and Drug Administration (FDA).

Low mercury fish are plentiful and include:

• anchovies
• cod
• flounder
• haddock
• salmon
• tilapia
• trout (freshwater)

Fatty fish like salmon and anchovies are especially good options, as they are high in omega-3 fatty acids, which are important for your baby.

This one will be tough for you sushi fans, but it’s an important one. Raw fish, especially shellfish, can cause several infections. These can be viral, bacterial, or parasitic infections, such as norovirus, Vibrio, Salmonella, and Listeria.

Some of these infections may only affect you, causing dehydration and weakness. Other infections may be passed on to your baby with serious, or even fatal, consequences.

Pregnant women are especially susceptible to listeria infections. In fact, according to the Centers for Disease Control and Prevention (CDC), pregnant women are up to 10 times more likely to get infected by Listeria than the general population. Pregnant Hispanic women are 24 times more at risk.

This bacteria can be found in soil and contaminated water or plants. Raw fish can become infected during processing, including smoking or drying.

Listeria bacteria can be passed to your baby through the placenta, even if you’re not showing any signs of illness. This can lead to premature delivery, miscarriage, stillbirth, and other serious health problems, according to the CDC.

It’s definitely advised to avoid raw fish and shellfish, including many sushi dishes. But don’t worry, you’ll enjoy it that much more after baby is born and it’s safer to eat again.

Some of the same issues with raw fish affect undercooked meat, too. Eating undercooked or raw meat increases your risk of infection from several bacteria or parasites, including Toxoplasma, E. coli, Listeria, and Salmonella.

Bacteria may threaten the health of your little one, possibly leading to stillbirth or severe neurological illnesses, including intellectual disability, blindness, and epilepsy.

While most bacteria are found on the surface of whole pieces of meat, other bacteria may linger inside the muscle fibers.

Some whole cuts of meat — such as tenderloins, sirloins, or ribeye from beef, lamb and veal — may be safe to consume when not cooked all the way through. However, this only applies when the piece of meat is whole or uncut, and completely cooked on the outside.

Cut meat, including meat patties, burgers, minced meat, pork, and poultry, should never be consumed raw or undercooked. So keep those burgers on the grill well done for now.

Hot dogs, lunch meat, and deli meat are also of concern, which is sometimes surprising to pregnant people. These types of meat may become infected with various bacteria during processing or storage.

Pregnant women should not consume processed meat products unless they’ve been reheated until steaming hot.

Raw eggs can be contaminated with the Salmonella bacteria.

Symptoms of salmonella infections include fever, nausea, vomiting, stomach cramps, and diarrhea.

However, in rare cases, the infection may cause cramps in the uterus, leading to premature birth or stillbirth.

Foods that commonly contain raw eggs include:

• lightly scrambled eggs
• poached eggs
• hollandaise sauce
• homemade mayonnaise
• some homemade salad dressings
• homemade ice cream
• homemade cake icings

Most commercial products that contain raw eggs are made with pasteurized eggs and are safe to consume. However, you should always read the label to make sure.

To be on the safe side, make sure to always cook eggs thoroughly or use pasteurized eggs. Save those super runny yolks and homemade mayo until after baby makes their debut.

Organ meat is a great source of a variety of nutrients.

These include iron, vitamin B12, vitamin A, zinc, selenium, and copper — all of which are good for you and baby. However, eating too much animal-based vitamin A (preformed vitamin A) is not recommended during pregnancy.

Consuming too much preformed vitamin A, especially in the first trimester of pregnancy, can lead to congenital malformations and miscarriage.

Although this is mostly associated with vitamin A supplements, it’s best to keep your consumption of organ meats like liver to just a few ounces once per week.

You may be one of the millions of folks who love their daily cups of coffee, tea, soft drinks, or cocoa. You’re definitely not alone when it comes to our love of caffeine.

Pregnant people are generally advised to limit their caffeine intake to less than 200 milligrams (mg) per day, according to the American College of Obstetricians and Gynecologists (ACOG).

Caffeine is absorbed very quickly and passes easily into the placenta. Because babies and their placentas don’t have the main enzyme needed to metabolize caffeine, high levels can build up.

High caffeine intake during pregnancy has been shown to restrict fetal growth and increase the risk of low birth weight at delivery.

Low birth weight — defined as less than 5 lbs., 8 oz. (or 2.5 kg) — is associated with an increased risk of infant death and a higher risk of chronic diseases in adulthood.

So keep an eye on your daily cup of joe or soda to make sure baby doesn’t have exposure to too much caffeine.

Your healthy salad choice may not be free from rogue ingredients, either. Raw sprouts, including alfalfa, clover, radish, and mung bean sprouts, may be contaminated with Salmonella.

The humid environment required by seeds to start sprouting is ideal for these kinds of bacteria, and they’re almost impossible to wash off.

For this reason, you’re advised to avoid raw sprouts altogether. However, sprouts are safe to consume after they have been cooked, according to the FDA.

The surface of unwashed or unpeeled fruits and vegetables may be contaminated with several bacteria and parasites.

These include Toxoplasma, E. coli, Salmonella, and Listeria, which can be acquired from the soil or through handling.

Contamination can occur at any time during production, harvest, processing, storage, transportation, or retail. One dangerous parasite that may linger on fruits and vegetables is called Toxoplasma.

The majority of people who get toxoplasmosis have no symptoms, while others may feel like they have the flu for a month or more.

Most infants who are infected with the Toxoplasma bacteria while still in the womb have no symptoms at birth. However, symptoms such as blindness or intellectual disabilities may develop later in life.

What’s more, a small percentage of infected newborns have serious eye or brain damage at birth.

While you’re pregnant, it’s very important to minimize the risk of infection by thoroughly washing with water, peeling, or cooking fruits and vegetables. Keep it up as a good habit after baby arrives, too.

Raw milk, unpasteurized cheese, and soft-ripened cheeses can contain an array of harmful bacteria, including Listeria, Salmonella, E. coli, and Campylobacter. (These are probably sounding familiar by now.)

The same goes for unpasteurized juice, which is also prone to bacterial contamination. These infections can all have life-threatening consequences for an unborn baby.

The bacteria can be naturally occurring or caused by contamination during collection or storage. Pasteurization is the most effective way to kill any harmful bacteria, without changing the nutritional value of the products.

To minimize the risk of infections, eat only pasteurized milk, cheese, and fruit juice.

It’s advised to completely avoid drinking alcohol when pregnant, as it increases the risk of miscarriage and stillbirth. Even a small amount can negatively impact your baby’s brain development.

Drinking alcohol during pregnancy can also cause fetal alcohol syndrome, which involves facial deformities, heart defects and intellectual disability.

Since no level of alcohol has been proven to be safe during pregnancy, it’s recommended to avoid it altogether.

There’s no better time than pregnancy to start eating nutrient-dense foods to help both you and your growing little one. You’ll need increased amounts of many essential nutrients, including protein, folate, choline, and iron.

It’s also a myth that you’re “eating for two.” You can eat as you normally do during the first semester, then increase by about 350 calories per day in your second trimester, and about 450 calories per day in your third trimester.

An optimal pregnancy eating plan should mainly consist of whole foods, with plenty of nutrients to fulfill yours and baby’s needs. Processed junk food is generally low in nutrients and high in calories, sugar, and added fats.

While some weight gain is necessary during pregnancy, excess weight gain has been linked to many complications and diseases. These include an increased risk of gestational diabetes, as well as pregnancy or birth complications.

Stick to meals and snacks that focus on protein, vegetables and fruits, healthy fats, and fiber-rich carbohydrates like whole grains, beans, and starchy vegetables. Don’t worry, there are lots of ways to sneak veggies into your meals without sacrificing taste.

When you’re pregnant, it’s essential to avoid foods and beverages that may put you and your baby at risk.

Although most foods and beverages are perfectly safe to enjoy, some, like raw fish, unpasteurized dairy, alcohol, and high mercury fish, should be avoided.

Plus, some foods and beverages like coffee and foods high in added sugar, should be limited in order to promote a healthy pregnancy.

Foods to avoid when pregnant

6-minute read

Listen

There are some foods you should not eat when you're pregnant because they might make you ill or harm your baby. Make sure you know the important facts about which foods you should avoid or take extra care with when you're pregnant. The best foods to eat are freshly cooked or freshly prepared food.

Some types of cheese

Don't eat mould-ripened soft cheese, such as brie, camembert and chevre (a type of goat's cheese) and others with a similar rind. You should also avoid soft blue-veined cheeses such as Danish blue or gorgonzola. These are made with mould and they can contain listeria, a type of bacteria that can harm your unborn baby.

Although infection with listeria (listeriosis) is rare, it is important to take special precautions in pregnancy because even a mild form of the illness in a pregnant woman can lead to miscarriage, stillbirth or severe illness in a newborn baby.

You can eat hard cheeses such as cheddar, parmesan and stilton, even if they're made with unpasteurised milk. Hard cheeses don't contain as much water as soft cheeses so bacteria are less likely to grow in them. Many other types of cheese are okay to eat, but make sure they're made from pasteurised milk. They include cottage cheese, mozzarella, cream cheese, paneer, haloumi, goat's cheese and processed cheeses such as cheese spreads.

Pâté

Avoid all types of pâté, including vegetable pâtés, as they can contain listeria.

Raw or partially cooked eggs

Make sure that eggs are thoroughly cooked until the whites and yolks are solid. This prevents the risk of salmonella food poisoning. Don’t eat foods that contain raw and undercooked eggs, such as homemade mayonnaise. If you wish to have dishes that contain raw or partially cooked eggs, consider using pasteurised liquid egg. Don’t use cracked or dirty eggs.

Raw or undercooked meat

Cook all meat and poultry thoroughly so it is steaming hot and there is no trace of pink or blood. Take particular care with poultry, pork, sausages and minced meat, including burgers.

Don't eat rare meat. Toxoplasmosis is an infection caused by a parasite that can be found in meat, soil, cat faeces and untreated water. If you are pregnant the infection can damage your baby, but it's important to remember that toxoplasmosis in pregnancy is very rare.

If you feel you may have been at risk, discuss it with your doctor, midwife or obstetrician. If you are infected while you're pregnant, treatment for toxoplasmosis is available.

Wash all surfaces and utensils thoroughly after preparing raw meat. It's also important to remember to wash and dry your hands after touching or handling raw meat. This will help to avoid the spread of harmful bugs such as salmonella, campylobacter and E. coli that can cause food poisoning.

Liver products

Don't eat liver or liver products such as liver pâté or liver sausage, as they may contain a lot of vitamin A. Too much vitamin A can harm your baby.

Supplements containing vitamin A

Don't take high-dose multivitamin supplements, fish liver oil supplements or any supplements containing vitamin A.

Some types of fish

Fish contains protein and essential omega-3 fatty acids, so it is recommended in pregnancy.

However, some types of fish have higher levels of mercury, which can affect the baby’s developing nervous system. It’s important to limit your intake of fish with higher levels of mercury. Shark (flake), broadbill, marlin and swordfish should be eaten no more than once a fortnight and don’t eat any other fish during that fortnight. Orange roughy and catfish should be eaten no more than once a week, and no other fish should be eaten during that week.

For more information about mercury in fish, visit Food Standards Australia.

Raw shellfish

Eat cooked rather than raw shellfish as it can contain harmful bacteria and viruses that can cause food poisoning and have a higher risk of listeria contamination.

Pre-packaged salads

Pre-prepared or pre-packaged fruit or vegetable salads, including those from buffets and salad bars have a higher risk of listeria contamination.

Certain fruit and vegetables

Don’t eat rockmelon, due to a risk of listeria, or bean sprouts, due to salmonella.

Sushi

Don’t eat chilled seafood such as raw oysters, sashimi and sushi, smoked ready-to-eat seafood and cooked ready-to-eat prawns, which have a higher risk of listeria contamination.

The safest way to enjoy sushi is to choose the fully cooked or vegetarian varieties, such as those that include:

• cooked seafood, for example fully cooked eel (unagi) or shrimp (ebi)
• vegetables, for example cucumber (kappa) maki
• avocado — for example California roll
• fully cooked egg

Cold cured meats

Cold cured meats include salami, parma ham, chorizo and pepperoni. In Australia, pregnant women are advised to avoid eating cold cured meats or smoked fish as there is a small risk of these foods harbouring listeria, or the toxoplasma parasite that causes toxoplasmosis. These include:

• cold meats from delicatessen counters and sandwich bars, and packaged, sliced ready-to-eat meats
• cold cooked ready-to-eat chicken (whole, portions, or diced)

Unpasteurised milk

If you have milk, drink only pasteurised or UHT (ultra-heat treated) milk (also called long-life milk). If only raw (unpasteurised) milk is available, boil it first. Don’t drink unpasteurised goat’s or sheep’s milk or eat food that is made out of them, such as soft goat’s cheese.

Don't eat soft-serve ice-creams while you're pregnant as they have a higher risk of listeria contamination.

Alcohol

There is no safe level of alcohol that you can have during your pregnancy. Whether you are planning a pregnancy, already pregnant or breastfeeding, not drinking is the safest option as alcohol can harm your unborn baby.

Caffeine

High levels of caffeine can increase the risk of miscarriage, low birth weight and experiencing a difficult birth. Caffeine is naturally found in lots of foods, such as coffee, tea and chocolate, and is added to some soft drinks and energy drinks. Some cold and flu remedies also contain caffeine. Talk to your midwife, doctor or pharmacist before taking these remedies.

You don’t need to cut out caffeine completely, but don’t have more than 200mg a day. The approximate amounts of caffeine found in food and drinks are:

• 1 cup of instant coffee: 60mg
• 1 shot of espresso coffee: 100mg
• 1 cup of plunger coffee: 80mg
• 1 cup of tea: 30mg
• 375ml can of cola: 49mg
• 250ml can of energy drink: 80mg
• 100g bar of milk chocolate: 20mg

Don’t worry if you occasionally have more than 200mg, the risks are quite small. To cut down on caffeine, try decaffeinated tea and coffee, fruit juice or mineral water instead of regular tea, coffee and cola.

Energy drinks

Energy drinks are not recommended during pregnancy as they may contain high levels of caffeine, and other ingredients not recommended for pregnant women.

Foods with soil on them

Wash fruit, vegetables and salads to remove all traces of soil and visible dirt. Learn more about safe food preparation.

Peanuts and allergies

If you would like to eat peanuts or food containing peanuts (such as peanut butter) during pregnancy, you can choose to do so as part of a healthy balanced diet, unless you are allergic to them or your health professional advises you not to. Exclusion of any particular foods (including foods considered to be highly allergenic) from the maternal diet during pregnancy or breastfeeding is not recommended, as this has not been shown to prevent allergies in your baby.
