Excessive caffeine intake during pregnancy has been linked to an increased risk of miscarriage, preterm birth, and low birth weight. Caffeine crosses the placenta and is metabolized much more slowly by the developing fetus, which can impact fetal heart rate and development. While coffee is a well-known source of caffeine, sodas, energy drinks, and even some teas and chocolates also contribute to daily intake. For example, a typical 8-ounce cup of coffee contains about 95 mg of caffeine, while a 12-ounce can of cola has 30-40 mg.

The American College of Obstetricians and Gynecologists (ACOG) recommends that pregnant women limit caffeine consumption to less than 200 mg per day. This equates to roughly one 12-ounce cup of coffee or two cans of cola. Reading beverage labels and being mindful of serving sizes is essential for staying within safe limits. If you wish to further reduce caffeine intake, try decaffeinated coffee, herbal teas (avoiding those not recommended in pregnancy), or naturally caffeine-free drinks like water and fruit juices. Following these guidelines helps support optimal fetal growth and reduces potential pregnancy complications.

11. Alcohol

Organ meats, such as liver, kidney, and heart, are rich sources of essential nutrients including iron, zinc, and vitamin B12. However, liver and other organ meats contain exceptionally high levels of preformed vitamin A (retinol). Consuming large amounts of preformed vitamin A during pregnancy can lead to toxicity, which has been linked to birth defects and liver damage in the developing fetus. Unlike muscle meats, which provide protein and moderate amounts of micronutrients, organ meats can deliver many times the daily recommended allowance of vitamin A in just a single serving.

The National Institutes of Health (NIH) and other health authorities recommend that pregnant women avoid excessive consumption of organ meats, particularly liver. It is generally considered safe to consume organ meats only occasionally and in small quantities, limiting intake to no more than once a week and ensuring the total daily vitamin A intake does not exceed 3,000 micrograms (mcg) of retinol activity equivalents (RAE). For those seeking iron or other nutrients found in organ meats, lean muscle meats, eggs, and plant-based sources are safer alternatives during pregnancy. Always consult with a healthcare provider about dietary choices involving organ meats to ensure a healthy pregnancy.

Leftover takeout foods, such as pizza, fried rice, or pasta dishes, can become breeding grounds for harmful bacteria if not stored or reheated properly. Bacteria like Bacillus cereus, Salmonella, and Staphylococcus aureus can multiply rapidly when food is left at room temperature for more than two hours, increasing the risk of foodborne illness. Pizza, for example, is often left out after meals and then consumed cold, but the cheese and toppings can harbor bacteria if not refrigerated promptly. The Centers for Disease Control and Prevention (CDC) recommends refrigerating leftovers within two hours and consuming them within three to four days for safety.

When reheating leftovers, ensure the food reaches an internal temperature of at least 165°F (74°C) to kill any potential bacteria. Use a food thermometer for accuracy, and reheat sauces, soups, and gravies until they reach a rolling boil. Avoid reheating leftovers more than once and discard any takeout that smells off or has changed in texture or color. By following these reheating and storage guidelines, pregnant women can safely enjoy leftover takeout while minimizing the risk of foodborne illness for themselves and their developing babies.

Raw cookie dough is a tempting treat, but it poses significant risks for pregnant women due to the presence of both raw eggs and uncooked flour. Raw eggs can harbor Salmonella, which can cause serious gastrointestinal illness and complications during pregnancy. Less commonly known, uncooked flour can also be contaminated with harmful bacteria such as E. coli. Outbreaks traced to raw flour have led to product recalls and warnings from the Centers for Disease Control and Prevention (CDC), which emphasizes that no one, especially pregnant women, should eat raw dough or batter.

In contrast, baked cookies are safe because the heat from baking kills bacteria in both the eggs and flour. If you crave the taste of cookie dough, look for commercial “edible cookie dough” that is made with pasteurized eggs or egg substitutes and heat-treated flour, or try recipes specifically designed to be eaten raw. Always read labels for safety information. By waiting until cookies are fully baked or choosing specially formulated alternatives, pregnant women can enjoy sweet snacks without risking exposure to harmful pathogens.

31. Energy Drinks

31. Energy Drinks
Energy drinks pose heightened risks in pregnancy due to unregulated caffeine and stimulant content.

Energy drinks are popular for their ability to boost alertness, but they often contain extremely high levels of caffeine and other stimulants, such as guarana and taurine. During pregnancy, excessive caffeine intake can increase the risk of miscarriage, preterm birth, and low birth weight. Unlike moderate coffee consumption—where the amount of caffeine can be monitored and limited to under 200 mg per day as recommended by the American College of Obstetricians and Gynecologists (ACOG)—energy drinks can easily exceed this threshold in just one serving.

Additionally, energy drinks often feature a mix of herbal additives and artificial ingredients, many of which have not been studied for safety in pregnancy. The Centers for Disease Control and Prevention (CDC) cautions that these unknown additives and excessive stimulants may have unpredictable effects on both the mother and developing baby. Pregnant women should avoid energy drinks entirely, opting instead for safer alternatives such as water, herbal teas (that are pregnancy-safe), or decaffeinated beverages. By steering clear of energy drinks, expectant mothers can better control their caffeine intake and avoid the risks associated with unregulated additives and stimulants.

32. Herbal Teas

Herbal teas are often marketed as natural remedies, but their ingredients are largely unregulated and may pose risks during pregnancy. Some herbal teas contain compounds that can stimulate the uterus, affect hormone levels, or interact with medications. For example, licorice root tea has been associated with increased risk of preterm birth and adverse effects on fetal brain development, as noted by the National Institutes of Health (NIH). Other herbs, such as sage, pennyroyal, and certain detox blends, may also be unsafe for pregnant women.

To choose safe teas, look for products labeled as suitable for pregnancy and consult your healthcare provider before trying new blends. Avoid herbal teas with ingredients you do not recognize or that have not been proven safe in pregnancy. Stick to moderate amounts of traditional teas, such as ginger or peppermint, which are generally regarded as safe for nausea or digestive discomfort but should still be consumed in moderation. Read packaging carefully and avoid teas that make bold, unsubstantiated health claims. By exercising caution and seeking professional guidance, pregnant women can enjoy the soothing benefits of tea while minimizing exposure to potentially harmful herbs and additives.

33. Excess Vitamin A Supplements

Vitamin A is essential for fetal growth and development, but excessive intake—particularly in the form of preformed vitamin A (retinol or retinyl esters)—can have teratogenic effects, meaning it can cause birth defects. High doses of preformed vitamin A have been linked to malformations of the heart, lungs, skull, and central nervous system. The National Institutes of Health (NIH) recommends that pregnant women avoid exceeding 3,000 micrograms (mcg) of preformed vitamin A per day from supplements and animal sources combined.

Not all forms of vitamin A are equally risky. Beta-carotene, the plant-based precursor found in fruits and vegetables, is generally considered safe because the body converts it to vitamin A only as needed. In contrast, preformed vitamin A from animal sources (such as liver) and many multivitamin or standalone supplements can easily lead to excessive intake. Pregnant women should always check supplement labels for the source and amount of vitamin A and choose prenatal vitamins formulated specifically for pregnancy, which contain safe levels. Consulting a healthcare provider before starting any new supplement ensures proper dosage and minimizes the risk of vitamin A toxicity, supporting healthy fetal development.

34. Blue Cheese

Blue cheeses, such as Roquefort, Gorgonzola, and Stilton, are known for their distinct flavor and veined appearance, but they pose particular risks during pregnancy if made from unpasteurized milk. Unpasteurized blue cheese can harbor Listeria monocytogenes, a bacterium that can survive and multiply even at refrigerator temperatures, leading to listeriosis—a potentially life-threatening infection for both mother and baby. The Centers for Disease Control and Prevention (CDC) warns that soft and semi-soft cheeses made from raw milk, including many blue cheeses, should be avoided during pregnancy.

Pasteurized blue cheeses are much safer options, as the heat treatment process eliminates harmful bacteria. Always check cheese packaging labels for the word “pasteurized” before purchasing or consuming blue cheese. Imported or artisanal blue cheeses are more likely to be unpasteurized, so when in doubt, ask the seller or choose a different cheese. When dining out, inquire about the type and origin of the cheese used in dishes or dressings. By opting for pasteurized blue cheese or skipping it entirely, pregnant women can enjoy a variety of flavors while protecting themselves and their babies from the dangers of listeria.

35. Raw Honey (for infants)

Raw honey is a natural sweetener that can sometimes contain spores of Clostridium botulinum, the bacteria responsible for infant botulism. While the digestive systems of healthy adults and pregnant women can handle these spores without harm, infants under 12 months old are at serious risk because their gut flora is not developed enough to prevent the spores from growing and producing botulinum toxin. According to the Centers for Disease Control and Prevention (CDC), infant botulism is a rare but potentially fatal illness that can cause muscle weakness, poor feeding, and breathing difficulties in babies.

It is safe for pregnant women to consume honey, including raw honey, as their mature digestive systems destroy any botulism spores before they can cause harm. However, it is crucial to ensure that honey is never given to infants under one year of age, whether directly or as an ingredient in foods prepared for them. All household members and caregivers should be aware of this guideline to protect infants from risk. By following these recommendations, families can safely incorporate honey into their diets while preventing the dangers of infant botulism.

36. Excess Salt

Consuming too much salt during pregnancy can contribute to high blood pressure (hypertension), swelling, and an increased risk of complications such as preeclampsia. Many processed and fast foods contain large amounts of sodium as a preservative and flavor enhancer, making it easy to exceed recommended limits. According to the Centers for Disease Control and Prevention (CDC), most people—including pregnant women—should aim to consume less than 2,300 milligrams of sodium per day.

Processed foods like canned soups, frozen meals, chips, and takeout are major contributors to excess salt intake, whereas home-cooked meals allow for better control over sodium levels. Cooking from scratch with fresh ingredients lets you season dishes to taste while using herbs and spices as alternatives to salt. To moderate intake, read nutrition labels carefully, choose “low sodium” or “no added salt” products, and limit the use of salty condiments like soy sauce or salad dressings. Taste food before adding extra salt at the table. By prioritizing fresh, whole foods and mindful seasoning, pregnant women can help regulate their blood pressure and support a healthier pregnancy for themselves and their babies.

37. Spicy Foods

Spicy foods are enjoyed worldwide, but during pregnancy, they can sometimes cause gastrointestinal discomfort, including heartburn, indigestion, and acid reflux. These symptoms are already common in pregnancy due to hormonal changes and the growing uterus pressing on the stomach. The capsaicin in hot peppers and spicy seasonings can further irritate the digestive tract, exacerbating these issues. According to the American College of Obstetricians and Gynecologists (ACOG), spicy foods are not inherently dangerous for the baby, but they may increase maternal discomfort.

Milder peppers, such as bell peppers, tend to be less likely to trigger symptoms compared to hot varieties like jalapeños, habaneros, or chili powder-heavy dishes. If you enjoy spicy food, consider reducing the quantity of hot spices, opting for milder versions, or mixing spicy ingredients with dairy (such as yogurt or sour cream) to help neutralize capsaicin and soothe the stomach. Eating smaller, more frequent meals and staying upright after eating can further minimize discomfort. By making these adjustments, pregnant women can still enjoy flavorful dishes while reducing the likelihood of heartburn or digestive upset.

38. Excess Vitamin E Supplements

Vitamin E is an important antioxidant that supports immune function and cell health, but excessive intake during pregnancy can be harmful. High doses of vitamin E supplements have been linked to an increased risk of abdominal pain, nausea, bleeding, and in some studies, a higher risk of premature rupture of membranes and other pregnancy complications. The National Institutes of Health (NIH) recommends that pregnant women do not exceed 30 mg (about 45 IU) of vitamin E per day from all sources unless prescribed by a healthcare provider.

Vitamin E from food sources—such as nuts, seeds, spinach, and vegetable oils—is generally safe and unlikely to reach harmful levels. The concern arises mainly from overuse of dietary supplements, which can deliver amounts far above the recommended daily allowance. Pregnant women should check supplement labels and avoid taking vitamin E pills or prenatal vitamins that exceed the recommended dosage. Whenever possible, meet vitamin E needs through a balanced diet rich in whole foods. If supplementation is necessary, consult a healthcare professional to ensure it is both safe and appropriate for your individual pregnancy needs.

Frozen uncooked foods, such as frozen pizza, breaded chicken, or pre-formed burger patties, may seem safe due to their storage at low temperatures, but they can still harbor harmful bacteria like Salmonella and Listeria monocytogenes. Freezing does not kill these pathogens; it only halts their activity until the food is thawed or cooked. Consuming these products without thorough cooking can lead to foodborne illness, which is especially dangerous during pregnancy. For example, outbreaks linked to frozen, uncooked breaded chicken products have been reported by the Centers for Disease Control and Prevention (CDC).

Unlike freshly baked or fully cooked foods, frozen uncooked items require meticulous preparation. Always follow package instructions exactly, ensuring that foods are cooked to the recommended internal temperature—usually 165°F (74°C) for poultry and casseroles. Use a food thermometer to verify doneness, as appearance alone is not a reliable indicator. Avoid partial cooking or microwaving if the directions specify oven baking, as uneven heating can leave bacteria alive. By properly cooking frozen uncooked foods, pregnant women can safely enjoy their convenience while minimizing the risk of illness for themselves and their babies.

42. Unwashed Herbs
