Abstract

The lactose malabsorption was studied with hydrogen breath test among healthy adults.The results showed that 92% of them had lactose malabsorption,the percentages of the older subjects(30￣50y) drinking milk and with symptoms were significantly higher than those of the youth(18￣22y).All index examined are lower after consuming 12g lactose than those after consuming 25g lactose.Symptom of intolerance was related to the dose of consuming lactose.About 74% of healthy adults can tolerate 12g lactose.It suggests that the people with lactase deficiency can still drink milk,but its amounts should not exceed 250ml(equal to 12g lactose) every time.
