A new study published in Journal of Allergy and Clinical Immunology found that Infants who were first fed cow's milk at the age of 15 days or more had 19 times the risk of developing cow's milk allergy relative to those exposed earlier — during the first two weeks of life.
According to a recent report by Reuters Health, the finding that giving cow's milk very early in life might boost tolerance came as a surprise to lead researcher Yitzhak Katz of Tel Aviv University in Israel. He and his colleagues simply set out to improve on current estimates of the number of children with the allergy, and to determine how often it is accompanied by an allergy to soy. "We weren't even looking for a risk factor,” he says.
The researchers say the findings do not suggest that mothers should not breastfeed their babies, but rather, are an indication that cow’s milk can be used to supplement infant diets.
