Nutrition during pregnancy significantly affects maternal fitness and the overall health of both mother and child. A well-balanced diet rich in vitamins, minerals, and essential nutrients is vital for supporting fetal development and maintaining maternal energy levels. Key nutrients include folic acid for neural development, iron for increased blood volume, and calcium for bone health. Proper nutrition helps prevent complications like gestational diabetes and promotes healthier weight gain. Ultimately, focusing on a nutritious diet during pregnancy supports ongoing maternal fitness and contributes to positive outcomes for both the mother and baby.
