During pregnancy, protein needs significantly increase to support fetal development and maternal health. The recommended dietary allowance (RDA) for protein rises to about 71 grams per day for expectant mothers. Proteins play a crucial role in building tissues, producing enzymes and hormones, and supporting the pregnant individual's increased blood volume. Quality sources like lean meats, dairy, beans, and legumes are essential to meet these requirements. Ensuring adequate protein intake is vital for the health of both the mother and the developing baby, as it aids in proper growth and development.
