Along with regular checkups and moderate exercise, a well-balanced diet can help provide strength and energy, potentially supporting a smoother natural birth. Here are key dietary tips and recommended foods for the final stage of pregnancy.

f Key diet principles in late pregnancy

• Balanced nutrition: Maintain a healthy ratio of carbohydrates, protein, and fats.
• High-fiber intake: Helps prevent constipation and ease common late-pregnancy discomforts.
• Weight control: Avoid excessive weight gain to reduce the risk of macrosomia and C-section.
• Energy support: Provide steady energy for labor.
• Small, frequent meals: Reduce pressure on the stomach and aid digestion.

Foods that may support natural birth

• Dark green vegetables: Spinach, broccoli—rich in magnesium and calcium to relax muscles and nerves.
• High-fiber fruits: Apples, pears, kiwis—promote digestion and gut health.
• Quality protein: Fish, chicken, eggs, tofu—builds strength and supports muscle endurance.
• Whole grains: Brown rice, oats, quinoa—provide long-lasting energy.
• Nuts and seeds: Almonds, walnuts, sesame—supply healthy fats and essential minerals.
• Probiotic foods: Yogurt, kefir—help regulate gut flora and improve digestion.
• Adequate hydration: 1500–2000 ml of water daily to support circulation and metabolism.

 Foods and habits to limit

• Avoid fried and sugary foods to lower risks of gestational diabetes and excessive weight gain.
• Limit caffeine and spicy, irritating foods.
• Reduce high-salt intake to help prevent swelling and high blood pressure.

‍ Doctor’s note

Diet is only one factor. The chances of natural birth also depend on fetal position, pelvic condition, and contractions. Maintain healthy eating habits along with doctor-recommended exercises and checkups for the best preparation.
