In Disease-Proof Your Child Dr. Fuhrman makes it clear that breast milk is the human fuel that babies need to grow and develop:
The antibodies derived from mother’s milk are necessary for maximizing immune system function, maximizing intelligence, and protecting against immune system disorders, allergies, and even cancer. The child’s immune system is still underdeveloped until age of two, the same age when the digestive tract seals the leaks (spaces between cells) designed to allow the mother’s antibodies access to the bloodstream. So picking the age of two as the length of recommended breast-feeding is not just a haphazard guess, it matches the age at which the child is no longer absorbing the mother’s immunoglobulins to supplement their own immune system. Nature designed it that way.And it seems their might be something to the whole idea of “maximizing intelligence.” New research shows that people who were breastfed as children are more likely to move up the social ladder. Robert Preidt of HealthDay News reports:
Researchers at the University of Bristol analyzed data on more than 1,400 people from 16 rural and urban areas in England and Scotland who were born from 1937 to 1939. Among these people, the likelihood of being breast-fed was not dependent on household income, spending on food, birth order, number of siblings, or social class in childhood.
The study found that individuals who were breast-fed as babies were 41 percent more likely to advance up the social ladder than those who'd been bottle-fed. The longer a person was breast-fed, the more likely they were to be upwardly mobile.
