During pregnancy, certain foods pose higher risks than others due to potential contaminants such as harmful bacteria and high levels of mercury. It's essential for expectant mothers to be informed about these risks to ensure the health and safety of themselves and their developing babies.
Seafood and Mercury Exposure
Seafood can be an excellent source of omega-3 fatty acids, proteins, and other nutrients beneficial during pregnancy. However, it can also contain mercury, a toxic element that can interfere with the neurological development of a fetus. Pregnant individuals should avoid high-mercury fish like shark, swordfish, king mackerel, marlin, orange roughy, and bigeye tuna. Choosing lower-mercury fish such as skipjack tuna, shrimp, salmon, pollock, and cod is advised, aiming for up to 12 ounces a week.
Dairy and Pasteurization
Dairy products provide essential nutrients like calcium and vitamin D, but the key is to ensure they are pasteurized to avoid exposure to bacteria. Pregnant individuals should avoid unpasteurized milk and products made from it. Soft cheeses like brie, feta, camembert, queso blanco, and queso fresco can harbor listeria unless they are clearly labeled as made from pasteurized milk.
Meat, Poultry and Eggs
Protein sources such as meat, poultry, and eggs are vital for the growth and development of the fetus but they must be properly cooked. Pregnant individuals should avoid raw or undercooked meat, raw eggs, as well as unpasteurized meat spreads, and deli meats unless reheated to steaming hot temperatures. All poultry should be cooked to an internal temperature of 165°F and other meats to at least 160°F. Utilizing a meat thermometer ensures both safety and optimal cooking.
Foods to Specifically Avoid While Pregnant
When pregnant, certain items must be avoided to ensure the health and safety of both the mother and baby. These items range from certain beverages to raw produce that may contain harmful bacteria or chemicals.
Alcohol and Pregnancy
Alcohol is one of the most significant substances to avoid during pregnancy as it can lead to fetal alcohol syndrome, which may cause brain damage, vision issues, intellectual disabilities, and low birth weight. There is no known safe amount of alcohol during pregnancy, and all forms—beer, wine, and spirits—should be avoided entirely to prevent potential harm to the developing fetus.
Caffeinated Beverages and Pregnancy
Expectant mothers are advised to limit their caffeine intake. High caffeine consumption can be associated with risks such as low birth weight and preterm birth. Coffee and tea, the most common sources of caffeine, should be consumed in moderation; it is recommended to limit caffeine to less than 200 milligrams a day — roughly equivalent to one 8-ounce cup of brewed coffee.
Unwashed Vegetables and Sprouts
Eating unwashed fruits and vegetables can introduce harmful bacteria like E. coli or cause infections that may affect the placenta. Special caution is needed with sprouts, including alfalfa, radish, and clover, due to their high risk of contamination. These should be thoroughly cleaned or cooked to eliminate potential bacteria.
Additional High-Risk Items
Raw or undercooked eggs: Should be avoided to reduce the risk of Salmonella.
Unpasteurized dairy products and juices: These can contain Listeria or other bacteria leading to food poisoning and complications in pregnancy.
Soft cheeses: Like Brie and Camembert, often contain Listeria if unpasteurized.
Deli meats and pre-made meat salads: Should be avoided unless thoroughly heated to prevent Listeria infection.
