Early exposure to milk protein from cows increases allergy resistance later in life, study finds

ScienceDaily (2010-07-14) -- A researcher in Israel has found that babies who are fed cow milk protein early, in the form of infant formula, seem to be protected from developing an allergy to the same protein later in life.

Many doctors suggest that whole cow's milk be avoided in the early months of an infant's feeding. Lactation specialists go even further, counseling "mother's milk only" until baby starts eating solid food. But new research from Tel Aviv University says that mothers who feed their babies cow's milk in the first 15 days of life may be protecting their children from dangerous allergies later on.

說法頗極端。前者以晚點餵(能吃固態食物時)，或者根本只承認母奶，但是忒拉維夫的研究者卻認為出生15日內餵食牛奶可避免日後的過敏問題。
