摘要
本文用氢呼气试验对健康成人的乳糖吸收不良症进行了研究,结果发现:健康成人的乳糖吸收不良率(摄入25g乳糖)高达92%,中年人(30~50岁)的饮奶率和症状发生率均显著高于青年人(18~22岁)(P<0.05)。摄入12g乳糖与摄入25g乳糖相比,其乳糖吸收不良率,症状发生率,乳糖不耐受率均显著降低(P<0.05)。多数健康成人(74%)能够耐受12g乳糖,揭示乳糖酶缺乏者仍然可以一次摄入250ml牛奶(相当于12g乳糖)。
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.
