OUR INTEREST in dietary sodium was greatly stimulated by the surprising observation that an infant we were studying was ingesting 50-60 mEq of sodium daily from a diet of homogenized milk and commercial baby food. The patient, aged 15 months, was in chronic cardiac failure due to coarctation of the aorta.
