Can you eat tuna and safe fish intake during pregnancy

Can you eat tuna and safe fish intake during pregnancy

Why fish is recommended in pregnancy Fish is one of the few foods that can deliver lean protein, long-chain omega-3 fatty acids, iodine, vitamin D, vitamin B12, and trace minerals in a compact form. During pregnancy, these nutrients contribute to maternal tissue expansion, placental function, fetal growth, and neurodevelopment. DHA, in particular, is a major […]

Can you eat sushi and raw fish during pregnancy

Can you eat sushi and raw fish during pregnancy

The short answer: avoid raw fish, but not all sushi In many pregnancy food-safety guidelines, raw fish and raw shellfish are treated as higher-risk foods. That includes sashimi, nigiri with raw fish, ceviche, poke made with raw fish, raw oysters, raw clams, and raw scallops. The concern is not that every piece of raw fish […]

Mercury in fish and food poisoning risks in pregnancy

Mercury in fish and food poisoning risks in pregnancy

Why fish is both valuable and confusing in pregnancy Fish can be a nutrient-dense food in pregnancy. It supplies high-quality protein and, depending on the species, omega-3 fatty acids, iodine, selenium, vitamin D, and other micronutrients. DHA, an omega-3 fatty acid concentrated in oily fish, is relevant to fetal neurodevelopment and retinal development. For people […]

Food safety rules and listeria risk foods during pregnancy

Food safety rules and listeria risk foods during pregnancy

Why Listeria matters in pregnancy Listeria monocytogenes is a bacterium found in soil, water, animals, and food-processing environments. Unlike many foodborne pathogens, it can survive and grow at refrigerator temperatures. This makes it especially relevant to refrigerated ready-to-eat foods that are stored for days, handled after cooking, or eaten without further heating. Pregnancy involves complex […]

Foods to avoid and high-risk foods during pregnancy

Foods to avoid and high-risk foods during pregnancy

Why some foods are higher risk in pregnancy Pregnancy involves immunologic and physiologic adaptations that help support the fetus but may also increase susceptibility to some infections or make their consequences more serious. Foodborne illness can cause dehydration, fever, sepsis, miscarriage, preterm birth, stillbirth, or neonatal infection in severe cases. The absolute risk for any […]

Choline importance and prenatal vitamins: what to look for

Choline importance and prenatal vitamins: what to look for

What choline does in pregnancy Choline is an essential nutrient, often grouped with B vitamins because of its role in one-carbon metabolism, although it is not technically a vitamin. In pregnancy, demand rises because choline is needed for rapidly dividing fetal and placental tissues. It contributes to phosphatidylcholine and sphingomyelin, important structural components of cell […]

Omega-3 fatty acids and DHA supplements during pregnancy

Omega-3 fatty acids and DHA supplements during pregnancy

What omega-3 fatty acids are Omega-3 fatty acids are polyunsaturated fats that the body uses in cell membranes, immune signaling, vascular biology, and neurologic tissues. The three omega-3s most often discussed in nutrition are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). ALA is considered essential because humans cannot synthesize it and must […]

Calcium and vitamin D intake for pregnancy health

Calcium and vitamin D intake for pregnancy health

Why calcium and vitamin D matter in pregnancy Calcium is the most abundant mineral in the body and is essential for bone structure, muscle contraction, nerve conduction, blood clotting, and intracellular signaling. During pregnancy, calcium transfer to the fetus increases, particularly in the third trimester when fetal skeletal mineralization is most active. Maternal physiology adapts […]

Folic acid and iron requirements during pregnancy

Folic acid and iron requirements during pregnancy

Why folic acid matters before and during pregnancy Folate is a B vitamin needed for DNA synthesis, cell division, and red blood cell production. In pregnancy, these functions become especially important because the embryo, placenta, uterus, and maternal blood volume are all growing rapidly. Folic acid is the synthetic form used in most supplements and […]

Protein intake during pregnancy: how much is needed

Protein intake during pregnancy: how much is needed

Why protein matters in pregnancy Protein provides amino acids, which are required for maternal tissue expansion and fetal growth. During pregnancy, the body uses amino acids to build and remodel tissues, support enzymes and hormones, maintain immune function, and contribute to the placenta, uterus, breasts, and increased circulating blood proteins. Fetal growth depends on a […]
