Foods to Avoid During Pregnancy: What Should You Not Eat?

Pregnancy is an important time to pay closer attention to what you eat and drink. Most foods are perfectly safe during pregnancy, but some foods can increase the risk of food poisoning, infections, or exposure to substances that may affect your developing baby. Knowing which foods to avoid and which foods simply need to be limited can make pregnancy nutrition much easier.

The goal is not to follow an extremely restrictive diet. Instead, focus on eating a variety of nutritious foods while taking a few important precautions with meat, fish, dairy products, eggs, drinks, and food preparation.

Raw and Undercooked Meat

Raw or undercooked meat should be avoided during pregnancy. Meat that has not been cooked thoroughly can contain harmful bacteria or parasites that may cause food poisoning or infections.

This includes raw beef, chicken, turkey, lamb, and other meats, as well as dishes made with undercooked meat. Burgers, sausages, minced meat, and poultry should be cooked thoroughly rather than left pink or partially raw.

Cold cured meats such as salami, pepperoni, chorizo, and prosciutto also require extra care. Depending on the product and local guidance, they may need to be cooked thoroughly before eating.

Good food hygiene is equally important. Keep raw meat away from foods that are ready to eat, wash your hands after handling raw meat, and clean knives, cutting boards, and other kitchen surfaces properly.

Unpasteurized Milk and Some Soft Cheeses

Pregnant women should avoid unpasteurized milk and foods made from unpasteurized milk. These products can contain harmful bacteria, including Listeria, which can cause a serious infection during pregnancy.

When buying milk, yogurt, cheese, cream, or similar products, check the label to see whether the product has been pasteurized.

Some soft, mold-ripened, or blue-veined cheeses also require extra care. Certain cheeses may be safe when thoroughly cooked until steaming hot, while others are suitable when made with pasteurized ingredients according to local food-safety guidance.

Hard cheeses and many common pasteurized dairy products can generally be part of a healthy pregnancy diet.

Raw Fish and Raw Shellfish

Raw fish and raw shellfish should generally be avoided during pregnancy because they can contain harmful bacteria, viruses, or parasites.

This includes raw sushi, sashimi, raw oysters, and other dishes containing uncooked seafood. If you enjoy sushi, choose options containing properly cooked fish or cooked seafood instead.

Shellfish should also be cooked thoroughly before eating. Proper cooking reduces the risk of food poisoning.

Smoked or cured fish can also require additional precautions. Some products should be cooked thoroughly before being eaten during pregnancy, particularly when they are eaten cold.

Fish With High Mercury Levels

Fish can actually be an excellent food during pregnancy because it provides protein and important nutrients. However, some large fish can contain higher levels of mercury, which can be harmful to a developing baby's nervous system when exposure is excessive.

Certain fish should therefore be avoided during pregnancy, including shark, swordfish, and marlin.

Other types of fish may need to be limited rather than completely avoided. Tuna, for example, should be eaten according to recommended pregnancy limits.

Oily fish such as salmon, sardines, trout, mackerel, and herring can provide useful nutrients, but they should also be consumed within recommended limits.

The important point is that you do not need to avoid all fish during pregnancy. Choosing appropriate varieties and preparing them safely can allow fish to remain part of a balanced diet.

Raw or Partially Cooked Eggs

Eggs can be an excellent source of protein during pregnancy, but the way they are prepared matters.

Raw or partially cooked eggs may carry a risk of Salmonella depending on how the eggs were produced and local food-safety standards. If you are unsure whether eggs are suitable for eating partially cooked, it is safer to cook them thoroughly until both the white and yolk are firm.

Be particularly careful with foods made using raw eggs, such as homemade mayonnaise, certain desserts, mousses, and some sauces.

Commercial products may use pasteurized eggs, which can make them safer, but checking the label is still a good habit.

Liver and Liver Products

Liver and foods made with liver should be avoided during pregnancy because they can contain high levels of vitamin A.

Although vitamin A is an important nutrient, excessive amounts of certain forms of vitamin A can be harmful to a developing baby.

This is also why pregnancy supplements should be chosen carefully. Do not take vitamin A supplements or supplements containing retinol unless your healthcare professional has specifically recommended them.

Fish liver oil supplements can also contain high amounts of vitamin A and should not be taken during pregnancy unless advised by a healthcare professional.

Alcohol During Pregnancy

Alcohol is best avoided completely during pregnancy.

Alcohol crosses the placenta and can affect the developing baby. Because there is no established safe level of alcohol consumption during pregnancy, avoiding alcoholic drinks is the safest approach.

This includes beer, wine, spirits, cocktails, and other alcoholic beverages.

If you accidentally consume alcohol before realizing you were pregnant, do not panic. Speak with your doctor or midwife if you are concerned about what you consumed or how much you drank.

Limit Caffeine

Caffeine does not necessarily need to be completely eliminated during pregnancy, but it should be limited.

A commonly recommended limit is no more than 200 mg of caffeine per day. Caffeine can come from more than just coffee. Tea, cola, energy drinks, chocolate, and some supplements can also contain caffeine.

The amount can vary considerably between products. A large coffee from a café may contain much more caffeine than a small cup of instant coffee.

If you drink several caffeinated beverages throughout the day, consider the total amount rather than looking at each drink separately.

Wash Fruits and Vegetables Carefully

Most fruits and vegetables are safe and are an important part of a healthy pregnancy diet. However, they should be washed thoroughly before eating.

Fresh produce can carry soil, bacteria, or other contaminants. Wash fruits, vegetables, and salad ingredients carefully, particularly when they will be eaten raw.

Pre-cut fruit and ready-to-eat salads should also be stored correctly and consumed before their use-by dates.

Good kitchen hygiene is especially important during pregnancy. Wash your hands before preparing food, keep raw foods separate from ready-to-eat foods, and refrigerate foods appropriately.

What Can You Eat During Pregnancy?

There are still plenty of foods you can safely enjoy during pregnancy. Properly cooked meat and poultry, pasteurized dairy products, thoroughly cooked eggs, washed fruits and vegetables, beans, grains, nuts, and many types of fish can all form part of a balanced diet.

Pregnancy does not mean that you need to eat for two or completely change your normal diet. Instead, focus on variety, nutritious foods, adequate hydration, and safe food preparation.

If you are unsure about a particular food, check its ingredients and preparation method or ask your healthcare professional.

Final Thoughts

Knowing what foods to avoid during pregnancy does not mean you have to follow a complicated diet. The main precautions are straightforward: avoid alcohol, raw or undercooked meat and seafood, unpasteurized dairy products, high-mercury fish, and liver products. Limit caffeine and pay close attention to food preparation, washing, storage, and hygiene.

A balanced pregnancy diet can still include plenty of delicious and nutritious foods. If you have a medical condition, food allergy, nutritional deficiency, or specific dietary requirements, your healthcare professional can provide advice suited to your individual pregnancy.
