The nutritional choices made during pregnancy significantly affect the baby’s growth and development and the overall health of the mother. While focusing on the adequacy of both micro and macro nutrients, it’s equally important to know which foods and drinks to avoid to help reduce the risk of pregnancy complications. This article provides the list of foods, beverages, and contaminants to avoid to protect the mother and her developing child.
Raw Proteins
Raw or undercooked animal protein may contain harmful bacteria that can cause serious infections during pregnancy. These infections may increase the risk of complications of miscarriage, preterm labour, and poor foetal growth. The following is a list of foods to avoid for a healthy pregnancy.
- Raw or undercooked meat
- Ready to eat processed meats
- Raw or uncooked fish like sushi, ceviche, oysters
- Raw or soft-boiled egg or egg products like homemade mayonnaise, hollandaise sauce, tiramisu, or raw cookie dough
Organ Meats
Chicken liver is a rich source of preformed vitamin A (Retinol). Regular addition of such items in the pregnancy diet might pose the risk of Hepatic Hypervitaminosis A or Vitamin A toxicity. The developing foetus may develop severe congenital birth defects, cleft palate, and congenital heart disease due to malformations of the outflow tracts of the heart, and malformations of the central nervous system.
High Mercury Seafood
Methylmercury contamination in food has the potential to result in severe consequences for the cognitive and motor development of the neonate. Infants with microcephaly, considerable cognitive delays, and even cerebral palsy. Some have significant delays in learning to speak.
The following fish is considered risky to consume during pregnancy because they carry this neurotoxicant:
- Swordfish
- King Mackerel
- Tilefish
- Bigeye Tuna
Unpasteurised Milk
Unpasteurised milk and milk products like cheese, especially Brie, Camembert, Feta, Roquefort, and Queso Fresco, are common sources of Listeria. Such items naturally make it to the list of unhealthy foods during pregnancy.
Unwashed Fruits and Vegetables
Fresh fruits and vegetables support healthy foetal development; however, unwashed fruits and vegetables are among the foods not to eat while pregnant, as they may carry Toxoplasma or E.coli. Wash all fruits and vegetables thoroughly before peeling. Scrub the outer skin of vegetables and fruits to remove surface pathogens. Soak and rinse lettuce, spinach, and other leafy greens thoroughly, remove the stems, and remove the bruises from fresh fruits before consuming to protect yourself from potential diseases.
Avoid raw sprouts because they may contain harmful bacteria that cannot be washed away.:
- Alfalfa sprouts
- Clover sprouts
- Radish sprouts
- Mung bean sprouts
Raw sprouts should be cooked well before consuming.
Alcohol
There is no established safe lower limit for alcohol or ethanol consumption during pregnancy
Alcohol passes directly to your baby, whose body cannot process it. Drinking alcohol during pregnancy can increase the risk of miscarriage, poor growth, premature birth, and lifelong developmental problems, including Fetal Alcohol Spectrum Disorders (FASD).
The safest choice is to avoid alcohol completely throughout pregnancy.
Caffeine
The pregnancy diet restrictions on frequent coffee breaks are not unmerited. Caffeine can easily pass through the placenta from mother to baby. Too much caffeine may increase the risk of miscarriage, low birth weight, and restricted foetal growth. Try to limit your caffeine intake to no more than 200 mg per day, which is about one regular cup of coffee.
Processed Foods
Ultra-processed foods, refined sugars, and trans fatty acids are exactly the foods pregnant women should avoid. They are directly related to an increased risk of excessive gestational weight gain, pre-eclampsia, and gestational diabetes mellitus (GDM). Diabetes may lead to foetal macrosomia, where the baby is larger than average. Foetal macromelia often increases the risk for birth injury and shoulder dystocia during labour and delivery. In addition, ultra-processed foods and trans fatty acid-rich diets lack essential micronutrients (e.g., folate, iron, and calcium) that are needed to provide a healthy maternal and fetal physiology.
Conclusion
When planning a pregnancy diet, it is important to identify any biological, chemical, or nutritional risks associated with the foods. Expectant parents must consult their healthcare provider or dietitian to develop a personalised pregnancy nutrition plan. Only well-balanced meals fulfil the specific needs of pregnant women, ensuring a healthy pregnancy.
