Methods for evaluating risk of mother's milk or food inducing an onset of atopic dermatitis, and mother's milk or food with reduced risk of inducing an onset of atopic dermatitis

A method for preparing mother's milk with a reduced risk of inducing an onset of atopic dermatitis in an infant, the method comprising:

• providing a mother's milk obtained from a mother whose infant is at risk for atopic dermatitis, wherein the mother's milk comprises coenzyme A at a concentration of 0.5 nM or higher;
• and
• removing coenzyme A from the mother's milk to a control coenzyme A concentration at least two-fold less than 0.5 nM, wherein the control coenzyme A concentration is determined from a mother's milk whose infant does not develop atopic dermatitis, and wherein the removing step comprises:
• (i) contacting a liquid phase of the milk with a substance that binds to coenzyme A and (ii) separating coenzyme A from the liquid phase.
