Weanling mice fed chow or chow plus water supplemented with 3.5 mg of nucleotides per 100 ml of water for 6 weeks exhibited increased natural killer cell (NK) activity and lower macrophage activation compared to mice fed chow plus nonsupplemented water. In a dose‐response study, NK activity, macrophage activation and spleen weight (as a percentage of body weight) were higher in mice fed up to 0.035% w/w nucleotides, however macrophage activation was decreased by feeding over 0.35% w/w compared to those receiving basal purified diet (BPD). Nucleotides in human milk may affect the immune response in breast‐fed infants.
