In order for proper growth to occur, the mother has to have an adequate food intake to supply energy to support the pregnancy and the growing needs of the fetus. For an uncomplicated pregnancy in a mother of normal weight, a 25-35 pound weight gain in nine months is recommended. This may be accomplished by adding an extra 300 calories per day to her diet.
Proper nutrition is only one of many components affecting a healthy pregnancy and baby.
If maintaining a nutritional food plan is difficult for the mother, consultation with a registered dietician knowledgeable in pregnancy needs may be necessary and beneficial.
