Canadian Healthy Infant Longitudinal Development (CHILD)
Using data from more than 2,100 Canadian children, researchers found that infants who avoided cow’s milk products in their first year were nearly four times as likely to be sensitized to cow’s milk compared to infants who consumed cow’s milk products before 12 months of age. Similarly, infants who avoided egg or peanut in their first year were nearly twice as likely to be sensitized to those foods compared to infants who consumed them before 12 months of age.
