In the period of pregnancy a number of physiological modifications happen. Among the different changes, maternal metabolism is one of the important alteration. Nutritional prerequisite increases to meet this need. During the complete period of pregnancy, doctors say that it is quiet normal that a healthy mother’s weight increases by 16 to 20 pounds during the entire period of pregnancy. Within the last three months of pregnancy the baby puts on nearly ¾th of its total weight at birth.
Thus, throughout the time it gets from its mother about 75 percentage of its protein, 93 percentage of its fat, 65 percentages of its calcium and between 70 and 80 percentage of other minerals. This rough estimate shows how much of nutrition that the normal mother should intake. This healthy food also assists the mother’s need to build reserves to meet the stress of delivery and lactation.
