A questionnaire survey was conducted on the milk intake by 77 breast-fed infants born during the two years from January 2002 to December 2003.
Individual information on each infant and mother (weight, health condition, etc.), the amount of milk breastfed each day, and the amount of liquids other than breast milk taken each day were recorded.
The intake data were recorded from the age of one month old to 5 months old. The intake of milk in a day varied from case to case. Although a relationship emerged between the intake of breast milk and the increase in body weight during the early months, this relationship was not maintained as the infants grew.
The mean intake of breast milk per day was 777.8ml, this being higher than the figure of 750ml recommended before weaning in the 6-th Revised Edition of the Japanese Nutrition Intake.
