Pregnancy pathology encompasses: abortions, preterm births, premature release of the placenta, serological conflict, transferred pregnancies, as well as hypertension and diabetes. The pathological causes of pregnancies can be numerous: inappropriate lifestyle, diseases, age, obesity or addiction. Although some of these factors are uncontrollable, we can reduce the risk and complications through appropriate nutrition.
Foods that must be strictly avoided during pregnancy
Every expectant mother, regardless of pregnancy status, should adhere to principles of balanced nutrition. However, there is a category of foods that must be entirely avoided to ensure proper fetal development. These include: sweetened carbonated beverages, caffeinated drinks, confectionery, artificially sweetened products, peanuts, processed meats, smoked fish, processed foods, fast food, mold-ripened cheeses, alcohol, and all alcoholic beverages.
Pregnant women's diet for anemia
Anemia is one of the most prevalent conditions among pregnant women in Poland, often resulting from inadequate intake of iron, folic acid, and vitamin B12. To support proper fetal and placental development, which rely on iron reserves, a diet rich in lean beef, liver, turkey meat, fish, legumes, and fresh green vegetables is essential. Anemia may also stem from iron absorption disorders, inflammatory foci, chronic conditions, or severe bleeding during pregnancy. In such cases, conducting key tests, such as measuring ferritin levels, total iron-binding capacity, and iron absorption curves, is crucial. Another cause of anemia is a deficiency in vitamin B12 and folic acid. The recommended daily intake of folic acid is 40 mg, while vitamin B12 requires 0.24 mg. Excellent sources of these nutrients include green vegetables, tomatoes, and legumes. High amounts of folic acid are also found in liver, brewer's yeast, wheat, and eggs. If adequate intake of iron, folic acid, and vitamin B12 is unattainable, consulting a gynecologist or dietitian for potential supplementation is advisable. To prevent anemia, 30 mg of iron is recommended for the first 8 weeks of pregnancy, while diagnosed cases may require doses between 60 and 120 mg. Notably, folic acid supplementation should begin at least 6 months before conception, with a minimum of 6 weeks prior. Increased folic acid intake should be maintained until the end of the second trimester.
Nutrition for Pregnant Women with Cholestasis
Cholestasis is a condition characterized by impaired bile acid flow, occurring solely during pregnancy. The primary symptom is persistent itching, initially affecting the hands and feet but potentially spreading across the entire body as the condition progresses. While it does not directly endanger the mother's health, it can result in premature birth and, in 1-4% of cases, fetal demise. Pregnant women exhibiting cholestasis symptoms should be hospitalized, with treatment primarily involving the administration of ursodeoxycholic acid. A supportive dietary approach includes a high-protein, low-fat regimen. The diet should be enriched with vitamin B sources such as meat, organ meats, barley, buckwheat, whole-grain bread, nuts, eggs, cauliflower, cabbage, leafy greens, beans, and peas. Additionally, supplementation with vitamins E, K, and increased selenium intake is recommended.
Diabetes in Pregnancy: Essential Dietary Guidelines
Pregnant women may develop two types of diabetes: preeclampsia or gestational diabetes. The former affects women diagnosed with diabetes before conception, while the latter concerns future mothers who have not adjusted their nutrient intake. Symptoms can include severe dizziness, persistent fatigue, frequent urination, insatiable hunger, excessive thirst, and rapid weight gain. However, diabetes may also be asymptomatic, making regular screenings crucial. The condition impacts fetal development, increasing the risk of congenital defects, miscarriages, and birth complications such as fetal overgrowth. In cases of gestational diabetes, a tailored diet is vital to mitigate adverse effects. Meals should be consumed at least six times daily, with 40–50% of calories from carbohydrates, 30% from proteins, and 20–30% from fats. The diet should be varied, fiber-rich, and prepared with minimal processing. For pregnancy-related complications, a well-balanced diet can be pivotal for maternal and fetal health. Nutrient deficiencies can lead to severe consequences, underscoring the importance of mindful food choices.
