Breast-Feeding

Science has proved that breast-fed babies have a healthier start in life. Human milk contains a balance of nutrients that closely matches infant requirements for brain development, growth and a healthy immune system. Human milk also contains immunologic agents and other compounds that act against viruses, bacteria, and parasites. Since an infant's immune system is not fully developed until age 2, human milk provides a distinct advantage over formula.
Because breast milk provides protection against germs that a baby or mother may carry, studies in infant feeding have found lower rates of several chronic childhood diseases, including respiratory infections and ear infections, as well as symptoms such as diarrhea, among children who were breast-fed.
Research also suggests that breast-fed infants gain less weight and tend to be leaner at 1 year of age than formula-fed infants. This early indicator may influence later growth patterns, resulting in fewer overweight and obese children.
But infants aren't the only ones who benefit from breast-feeding. Mothers, too, are the recipients of many positive hormonal and physical effects. Breast-feeding releases a hormone in a woman's body that causes her uterus to return to its normal size and shape more quickly and reduces blood loss after delivery. In addition, according to the Blueprint, studies have shown that breast-feeding for longer periods of time (up to 2 years) and among younger mothers may reduce the risk of premenopausal and possibly postmenopausal breast cancer. Also, the risk of ovarian cancer may be lower among women who have breast-fed their children
