The workshop on host resistance was introduced by the review of epidemiologic studies by Michael S. Kramer from Canada. Kramer raised several questions about the validity of certain studies, but his review left little doubt that human milk feedings contribute to the protection of the infant against infections. With few exceptions, investigations of this protective capacity have focused upon the overall effect of breast feeding and thus do not allow assignment of specific protective function to individual factors in human milk. Kramer was less impressed with the studies reporting that breast-feeding protects against allergic disorders. The first two presentations of this workshop addressed the fate and function of human milk components of possible value in the infant’s host defense.
