Nutrition is one of the most important factors that impact health in all areas of the lifecycle. Pregnant women need adequate food and health care to deliver a healthy baby who has a good birth weight and a fighting chance for survival. In many regions of the world, the infant mortality rate is very high, meaning that many infants will not live to see their first birthday. Breastfeeding is the ideal method of feeding and nurturing infants, because breast milk contains many immunologic agents that protect the infant against bacteria, viruses, and parasites. Yet, less than 40 percent of infants world-wide are exclusively breastfed (no other food or drink, not even water) for the first four months of life. Children need adequate nutrition to develop and grow to their full potential.
