What Foods Can You Not Eat When Pregnant? A Comprehensive Guide

Are you pregnant and wondering, What Foods Can You Not Eat When Pregnant? FOODS.EDU.VN is here to guide you through the essential dietary restrictions during pregnancy for the health of both you and your baby. By understanding what to avoid, including high-mercury seafood, unpasteurized products, and undercooked meats, you can navigate your pregnancy with confidence and ensure a healthy outcome.

1. Why Is It Important to Know What Foods to Avoid During Pregnancy?

Knowing what foods to avoid during pregnancy is crucial because certain foods can pose risks to both the mother and the developing fetus. These risks range from foodborne illnesses to developmental issues caused by toxins like mercury and alcohol. Avoiding these foods helps ensure a healthier pregnancy and reduces the likelihood of complications.

According to the U.S. Food and Drug Administration (FDA), pregnant women are more susceptible to foodborne illnesses, which can have severe consequences for the baby. The FDA emphasizes the importance of avoiding high-mercury fish and unpasteurized products to protect the baby’s developing nervous system.

2. What Types of Seafood Should Be Avoided During Pregnancy?

During pregnancy, certain types of seafood should be avoided due to their high mercury content, which can harm the baby’s developing nervous system. It’s best to steer clear of fish like bigeye tuna, king mackerel, marlin, orange roughy, swordfish, shark, and tilefish. These fish tend to accumulate more mercury due to their size and lifespan.

2.1 Safe Seafood Options During Pregnancy

The Dietary Guidelines for Americans recommends that pregnant women eat 8 to 12 ounces (224 to 336 grams) of seafood a week, choosing options low in mercury. Safe choices include:

Fish Type	Mercury Level
Anchovies	Low
Black Sea Bass	Low
Catfish	Low
Cod	Low
Freshwater Trout	Low
Herring	Low
Light Canned Tuna	Low
Oysters	Low
Pollock	Low
Salmon	Low
Sardines	Low
Shad	Low
Shrimp	Low
Sole	Low
Tilapia	Low
Whitefish	Low

According to a study by the Environmental Protection Agency (EPA), these fish are generally safe to consume in moderation during pregnancy, providing essential nutrients without posing a significant mercury risk.

3. Why Is Raw or Undercooked Seafood Risky During Pregnancy?

Raw or undercooked seafood can harbor harmful bacteria and viruses that cause foodborne illnesses. Pregnant women are more susceptible to these infections, which can lead to serious complications, including miscarriage or premature labor.

3.1 Types of Seafood to Avoid Raw

Avoid the following raw or undercooked seafood:

Sushi
Sashimi
Ceviche
Raw oysters, scallops, and clams
Refrigerated uncooked seafood labeled nova style, lox, kippered, or smoked

3.2 Safe Preparation of Seafood

To safely consume seafood during pregnancy:

Cook fish to an internal temperature of 145 F (63 C).
Ensure the fish flakes easily with a fork and looks milky white throughout.
Cook shrimp, lobster, and scallops until they are milky white.
Cook clams, mussels, and oysters until their shells open. Discard any that do not open.

Sushi

Properly cooking seafood eliminates harmful pathogens, making it safe for consumption during pregnancy.

4. Is Undercooked Meat, Poultry, or Eggs Safe During Pregnancy?

Undercooked meat, poultry, and eggs can carry bacteria like Salmonella and Listeria, which can cause foodborne illnesses. During pregnancy, the risk of contracting these illnesses is higher, and the consequences can be more severe.

4.1 Guidelines for Cooking Meat and Poultry

Cook all meats and poultry thoroughly, using a meat thermometer to ensure proper internal temperatures.
Heat hot dogs and lunch meats until they are steaming hot to kill potential Listeria bacteria.
Avoid refrigerated pates and meat spreads. Canned and shelf-stable versions are safer.

4.2 Guidelines for Cooking Eggs

Cook eggs until the yolks and whites are firm.
Avoid foods that may contain raw or partly cooked eggs, such as homemade eggnog, raw batter, tiramisu, and homemade Caesar salad dressing.

According to the Centers for Disease Control and Prevention (CDC), cooking meat, poultry, and eggs to the recommended temperatures kills harmful bacteria, reducing the risk of foodborne illnesses during pregnancy.

5. Why Are Unpasteurized Foods a Concern During Pregnancy?

Unpasteurized foods, particularly dairy products and juices, can harbor harmful bacteria like Listeria and E. coli, which can cause severe infections. Pasteurization is a process that kills these bacteria, making the products safe for consumption.

5.1 Dairy Products to Avoid

Avoid soft cheeses like brie, feta, and blue cheese unless the label clearly states they are pasteurized or made with pasteurized milk.

5.2 Juices and Ciders to Avoid

Do not drink juice or cider that has not been pasteurized. Look for products labeled as pasteurized to ensure safety.

5.3 Safe Dairy and Juice Options

Many low-fat dairy products, such as skim milk, mozzarella cheese, and cottage cheese, are safe to consume if pasteurized. Pasteurized juices and ciders are also safe.

Ensuring that dairy and juice products are pasteurized significantly reduces the risk of foodborne illnesses during pregnancy.

6. How Important Is Washing Fruits and Vegetables During Pregnancy?

Washing fruits and vegetables thoroughly is essential to remove harmful bacteria, pesticides, and dirt that can cause illness. This is particularly important during pregnancy, as the immune system is somewhat suppressed, making pregnant women more susceptible to infections.

6.1 How to Properly Wash Produce

Wash all raw fruits and vegetables under running water before eating, cutting, or cooking.
Use a clean produce brush to scrub firm fruits and vegetables like melons and potatoes.
Dry the produce with a clean cloth or paper towel.

6.2 Sprouts and Pregnancy

Avoid eating raw sprouts, including alfalfa, clover, radish, and mung bean sprouts, as they can harbor harmful bacteria. Ensure sprouts are fully cooked before consumption.

The Food and Drug Administration (FDA) provides detailed guidelines on safely washing produce to minimize the risk of contamination during pregnancy.

7. How Does Caffeine Intake Affect Pregnancy?

Caffeine can cross the placenta and affect the baby. While the exact effects are not entirely clear, high caffeine intake has been linked to an increased risk of miscarriage and low birth weight.

7.1 Recommended Caffeine Limits

Most healthcare professionals recommend limiting caffeine intake to less than 200 milligrams (mg) per day during pregnancy.

7.2 Caffeine Content in Common Beverages

8-ounce (240-mL) cup of brewed coffee: Approximately 95 mg of caffeine
8-ounce (240-mL) cup of brewed tea: Approximately 47 mg of caffeine
12-ounce (360-mL) cola with caffeine: Approximately 33 mg of caffeine

By monitoring caffeine intake and choosing lower-caffeine options, pregnant women can minimize potential risks to the baby.

8. Are Herbal Teas Safe During Pregnancy?

The safety of herbal teas during pregnancy is not well-established, as the effects of many herbs on fetuses are unknown. It’s best to exercise caution and consult with a healthcare professional before consuming herbal teas.

8.1 Herbal Teas to Avoid

Avoid drinking herbal teas unless your healthcare professional has confirmed they are safe for pregnancy. This includes teas marketed specifically for pregnancy, as their safety is not always guaranteed.

8.2 Safer Beverage Alternatives

Consider safer beverage alternatives like:

Water
Pasteurized fruit juices
Decaffeinated teas

Consulting with a healthcare provider ensures informed decisions about herbal tea consumption during pregnancy.

9. Why Is Alcohol Prohibited During Pregnancy?

No amount of alcohol has been proven safe during pregnancy. Alcohol consumption can lead to miscarriage, stillbirth, and fetal alcohol syndrome, which can cause facial deformities and intellectual disabilities.

9.1 Risks of Alcohol Consumption

Drinking alcohol during pregnancy poses significant risks to the developing fetus, including:

Miscarriage
Stillbirth
Fetal alcohol syndrome (FAS)

9.2 Seeking Help for Alcohol Concerns

If you are concerned about alcohol consumption before knowing you were pregnant or need help to stop drinking, consult a healthcare professional.

Organizations like the National Institute on Alcohol Abuse and Alcoholism (NIAAA) offer resources and support for pregnant women struggling with alcohol use.

10. What Are Some Lesser-Known Foods and Drinks to Avoid During Pregnancy?

Besides the commonly known foods, some lesser-known items should also be avoided or consumed with caution during pregnancy. These include certain types of spices, herbs, and processed foods that may contain harmful additives.

10.1 Specific Foods and Drinks to Be Cautious About

Licorice: Contains glycyrrhizin, which can potentially lead to premature labor.
Raw Milk Cheeses: Some artisan cheeses made from raw milk may not be pasteurized, increasing the risk of Listeria.

Artificial Sweeteners: While generally considered safe in moderation, some experts recommend limiting intake of artificial sweeteners during pregnancy.
Processed Foods High in Additives: These may contain artificial colors, flavors, and preservatives that could be harmful.

10.2 Why These Foods Are Problematic

These foods can pose risks due to various factors:

Licorice: Glycyrrhizin can affect hormone levels, potentially leading to complications.

Artificial Sweeteners: Concerns exist about their long-term effects on the baby’s health.
Processed Foods: Additives may trigger allergic reactions or have unknown impacts.

10.3 Safer Alternatives and Considerations

Licorice: Opt for licorice-flavored teas or candies in very small quantities.
Raw Milk Cheeses: Choose pasteurized cheeses clearly labeled.
Vitamin A: Obtain Vitamin A from natural sources like carrots and sweet potatoes.
Artificial Sweeteners: Use natural sweeteners like honey or maple syrup sparingly.
Processed Foods: Prioritize fresh, whole foods over processed options.

11. What About Deli Meats? Are They Safe During Pregnancy?

Deli meats can be a source of Listeria, a type of bacteria that can cause serious infections, especially in pregnant women. Listeria can cross the placenta and infect the baby, leading to miscarriage, premature delivery, or severe illness in the newborn.

11.1 Risks of Deli Meats

Listeria Contamination: Deli meats can be contaminated during processing or storage.
Higher Susceptibility in Pregnancy: Pregnant women are more susceptible to Listeria infections.

11.2 Safe Practices for Consuming Deli Meats

Check Expiration Dates: Ensure the deli meats are fresh and within their expiration dates.
Proper Storage: Store deli meats properly in the refrigerator to prevent bacterial growth.

11.3 Safer Alternatives

Cooked Meats: Opt for freshly cooked meats over deli meats.
Canned Meats: Canned meats are typically processed to kill bacteria and can be a safer alternative.
Vegetarian Options: Consider vegetarian options like hummus or avocado as fillings for sandwiches.

According to the American College of Obstetricians and Gynecologists (ACOG), heating deli meats until steaming hot significantly reduces the risk of Listeria infection during pregnancy.
