Breast milk
Each year in the U.S. roughly 27% of infants and children are affected by disease. Breastfeeding can lower the risk of respiratory, gastrointestinal, and other potentially life-threatening diseases. It offers protection against obesity and diabetes later in life, too. Breast milk is proven to be chemically different for each mother and infant pair. For example, a premature infant's mother will have different milk than a mature infant's mother. Breast milk can also change if an infection is detected in the infant. This natural prevention is tailored toward each infant.
