Milk and lactose-hydrolyzed milk

D Payne-Bose, JD Welsh, HL Gearhart and RD Morrison

Seven females 18 to 26 years old (mean 23 years) who were lactose malabsorbers as determined by a lactose tolerance test were given two different test meals: 5 ml/kg body weight reconstituted nonfat dry milk and 5 ml/kg body weight reconsituted nonfat dry milk in which 92% of the lactose had been hydrolyzed to glucose and galactose. Lactose malabsorption was determined by the breath H2 test. Tests were done in duplicate for a total of 28 tests. Whether a 3-hr test period of a 5-hr test period was used, the average breath H2 response after the lactose- hydrolyzed nonfat dry milk test meals was significantly lower (P less than 0.002) than the average breath H2 response after the nonfat dry milk test meals. There were significant differences among individual responses (P lless than 0.06 for the 3-hr test period and P less than 0.09 for the 5-hr test period), and no significant differences between duplicate test days.
