During pregnancy, it's crucial to steer clear of certain foods that may pose a risk of infection, particularly those that are undercooked or raw, such as meat or fish. Additionally, it’s wise to limit your consumption of caffeine and processed foods to ensure optimal health. Maintaining a nutritious diet during this vital time is essential for both your well-being and that of your unborn child. While you might have to forgo some of your beloved treats, including sushi, coffee, or rare steak, there are still numerous healthy options available to you.

With that in mind, let’s explore 15 foods and beverages that are best to avoid or minimize during pregnancy.

1. Fish with Elevated Mercury Levels

Mercury is a highly toxic element that can be found in contaminated waters, posing significant health risks. When present in elevated levels, it can adversely impact your nervous system, immune function, and renal health. Particularly concerning is its potential to cause serious developmental issues in children, with harmful effects occurring even at lower concentrations. Due to their size, larger marine fish often accumulate significant amounts of mercury, making it advisable for pregnant and breastfeeding individuals to steer clear of these high-mercury fish.

A list of fish to avoid includes:

• Shark
• Swordfish
• King mackerel
• Tuna (especially bigeye tuna)
• Marlin
• Tilefish from the Gulf of Mexico
• Orange roughy

2. Undercooked or Raw Fish

Consuming raw fish, particularly shellfish, poses a significant risk due to the potential presence of harmful bacteria or parasites, including norovirus, Vibrio, Salmonella, and Listeria. These pathogens can find their way into the fish during various stages such as handling, storage, and processing methods like smoking or drying.

Infection from these microorganisms can lead to severe dehydration and fatigue in expectant parents, and concerningly, some infections can be transmitted through the placenta to the unborn baby, even in the absence of obvious symptoms. This can heighten the risks of preterm birth, miscarriage, stillbirth, and other significant health complications. According to health authorities, pregnant individuals face a markedly increased risk of listeria infection, which can be up to three times greater compared to other times in life. This brings into question the safety of consuming raw fish during pregnancy.

3. Raw or Undercooked Meat

Consuming raw or insufficiently cooked meat significantly elevates your risk of contracting infections from various bacteria or parasites, including Toxoplasma, E. coli, Listeria, and Salmonella. These microorganisms not only pose a serious threat to your health but can also jeopardize the well-being of your little one. While most bacteria are typically found on the surface of whole meat cuts, some can reside within the muscle fibers themselves. For instance, whole cuts like tenderloins, sirloins, or ribeye from beef, lamb (mutton), and veal may be considered safe to consume if they are not fully cooked, provided that the exterior is adequately cooked. However, during pregnancy, it is prudent to completely avoid any form of undercooked meat to ensure safety.

On the other hand, processed or cut meats such as meat patties, burgers, minced meat, pork, and poultry should never be consumed raw or undercooked due to the heightened risk involved.

4. Processed and Deli Meats

Processed foods like hot dogs, lunch meats, pepperoni, and other types of deli meats may carry a risk of contamination with various harmful bacteria during their production or storage phases. Since cured meats are typically not cooked, they can harbor bacteria or even parasites, which pose health risks. Moreover, these processed meats are often laden with excessive amounts of sodium and unhealthy fats, which can adversely affect your health. To promote better health, it is advisable to steer clear of deli meats. When consuming processed meats like sausages, always ensure they are thoroughly cooked before eating.

5. Raw Eggs

Raw eggs have the potential to harbor Salmonella bacteria, a pathogen that can lead to severe health issues. The symptoms associated with a salmonella infection can range from fever and nausea to vomiting, abdominal cramps, and diarrhea. In pregnant women, this infection may even lead to additional complications such as uterine cramps, which could result in preterm birth or stillbirth.

Several culinary items that often include raw eggs are:

• Gently scrambled eggs
• Tiramisu
• Raw batter
• Hollandaise sauce
• Homemade mayonnaise
• Some salad dressings made from scratch
• Homemade egg nog
• Homemade ice cream
• Certain types of cake icings made at home
• Eggs Benedict

Fortunately, most commercial products that contain raw eggs utilize pasteurized eggs, making them safe for consumption. Nevertheless, it is essential to carefully check the label to confirm this. Always ensure that eggs are cooked thoroughly or opt for pasteurized eggs to minimize risk.

6. Organ Meat

Organ meats, also known as offal, are rich in a variety of essential nutrients including iron, vitamin B12, vitamin A, zinc, selenium, and copper, all of which are beneficial for both maternal and fetal health. These nutrients play a pivotal role in development and can significantly impact overall well-being.

However, it is crucial to be cautious with the intake of preformed vitamin A, particularly during the first trimester of pregnancy, as excessive consumption can lead to congenital anomalies and even pregnancy loss. While this concern is primarily associated with vitamin A supplements, it is advisable to limit the intake of organ meats such as liver (kaleji) and kidney (kidney) to just a few ounces each week.

7. Raw Sprouts

Raw sprouts, such as alfalfa (lucerne), clover, radish, and mung bean (moong) sprouts, are a delightful addition to salads, bringing both texture and nutritional value. However, the moist conditions required for sprouting seeds create an ideal breeding ground for harmful bacteria like Salmonella, which can be difficult to eliminate through washing alone. Therefore, it is advisable to steer clear of raw sprouts unless they are thoroughly cooked, ensuring they are safe for consumption. What should you understand about raw sprouts?

8. Unwashed Fruits and Vegetables

The outer layer of unwashed or unpeeled fruits and vegetables can harbor harmful bacteria and parasites, including Toxoplasma, E. coli, Salmonella, and Listeria. These contaminants can originate from the soil, improper handling, or various stages of the food supply chain. Contamination can take place at numerous points, including during production, harvesting, processing, storage, transportation, or even at retail locations.

Toxoplasma is a persistent parasite that can survive on plant-based foods. While many individuals remain asymptomatic, the parasite poses significant risks during pregnancy, as it can cross the placenta and lead to serious complications such as vision impairment and cognitive challenges later in life. In some instances, this could result in severe eye or brain damage present at birth. To effectively reduce the risk of infection, it is essential to thoroughly cleanse all fruits and vegetables with potable water, and consider peeling or cooking them before consumption.

9. Unpasteurized Dairy Products

Raw milk and various unpasteurized dairy products may harbor harmful bacteria, including Listeria, Salmonella, E. coli, and Campylobacter. These pathogens can lead to a spectrum of infections commonly referred to as food poisoning. These infections can pose serious, life-threatening risks, particularly for an unborn baby. The presence of these bacteria can either be natural or arise from contamination during the collection or storage processes. Fortunately, pasteurization effectively eliminates any harmful bacteria while preserving the nutritional value of the products. To minimize the risk of infections, it is advisable to consume only pasteurized dairy products.

10. Soft Cheeses

When it comes to soft cheeses, it's essential to be cautious as they may harbor listeria, a bacteria that poses significant health risks, especially during pregnancy, potentially leading to severe illness or even pregnancy loss. It's advisable to avoid cheeses such as queso fresco, queso blanco, queso blando, queso panela, and queso ranchero unless they are pasteurized. To ensure safety during pregnancy, always choose soft cheeses that clearly indicate they are pasteurized on their packaging. This label guarantees that the cheese has been treated to eliminate harmful bacteria, making it safer for consumption. So, what are the cheeses that can be safely enjoyed during pregnancy? Opt for varieties like mozzarella, cream cheese, and ricotta, which are typically made from pasteurized milk.

11. Processed Foods

Foods that are heavily processed usually lack essential nutrients while being packed with calories, added sugars, and unhealthy fats, which can contribute to an increased risk of weight gain. This is particularly concerning during pregnancy when a balanced intake of vital nutrients such as protein, folate, choline, and iron is crucial for both mother and baby. While gaining some weight is a natural part of pregnancy, excessive weight gain can lead to complications during delivery and may increase the likelihood of childhood obesity.

It's important to focus on meals and snacks that prioritize sources of protein, along with a variety of vegetables and fruits, healthy fats, and fiber-rich carbohydrates such as whole grains, legumes (dal), and starchy vegetables. Additionally, consider innovative ways to incorporate more vegetables into your meals without compromising on flavor.

12. A Variety of Fruit Juices and Smoothies

During pregnancy, fruit juices can offer numerous benefits, but it is essential to choose those that are pasteurized and free from any added sugars to ensure safety and nutrition. While enjoying fresh juices, be cautious of raw options, particularly those squeezed at market stalls, as they may harbor harmful bacteria. Similarly, when indulging in smoothies, which can sometimes contain unpasteurized juice, it is wise to inquire about the ingredients if dining out at a restaurant. This ensures that you are making informed choices for your health and the baby’s development.

13. Alcohol

When it comes to pregnancy, alcohol consumption poses serious risks, including increased chances of pregnancy loss, stillbirth, and the development of fetal alcohol syndrome (FAS). This syndrome can significantly impact various developmental aspects, particularly affecting the heart and brain of the fetus. As there is currently no established safe level of alcohol intake during pregnancy, the most prudent choice is to refrain from consuming any alcoholic beverages entirely.

To gain further insights, explore additional information about pregnancy, alcohol, and drug use.

14. Caffeine

Caffeine is present in a variety of beverages such as coffee, tea, soft drinks, and cocoa. These popular drinks are enjoyed worldwide, but it's essential to understand their implications, especially during pregnancy. Research indicates that consuming high amounts of caffeine can lead to several adverse pregnancy outcomes, including the risk of pregnancy loss, stillbirth, low birth weight, and various developmental challenges.

This stimulant is absorbed rapidly into the bloodstream and can easily cross the placenta. Since fetuses and their placentas lack the enzyme required to metabolize caffeine effectively, elevated levels of caffeine can accumulate, posing potential risks. In light of these findings, the American College of Obstetricians and Gynecologists (ACOG) advises that pregnant individuals limit their caffeine consumption to less than 200 milligrams (mg) per day to ensure safety for both mother and baby.

15. Contaminated Drinking Water

Staying hydrated is crucial during pregnancy, as it helps prevent dehydration and supports overall health. In many countries, including India and Australia, the majority of tap water is generally safe for consumption; however, it’s important to be cautious. Contaminants found in unclean or polluted drinking water can pose significant risks to both you and your developing baby. This is especially true for those relying on private wells, as these sources often lack the oversight of local health authorities, such as the Environmental Protection Agency in the United States. If you have any doubts regarding the safety of your drinking water, it is advisable to reach out to your local health authority or environmental agency for guidance and testing options.
