目的寻找膳食改善牛奶不耐受的措施。方法采用氢呼气试验从38名受试者中筛选出8名有水样状腹泻的乳糖不耐受者,参加用正交实验设计的不同食物与25 g 奶粉搭配的饮奶试验;采用随机整群抽样方法选取健康大学生100名参加以不同方式摄入25 g 奶粉的饮奶试验,观察饮奶试验后出现的不耐受症状。结果受试者饮牛奶,同时摄入鸡蛋、馒头、锅魁、面包后氢呼气浓度比单独饮用牛奶均有降低(均小于1.786 mg/m~3);正交直观分析、方差分析均表明:鸡货与牛奶混食者粪便乳糖和症状评分比馒头与牛奶混食者低,差异有统计学意义。全麦面包与牛奶混食者症状评分最高;不同饮奶方式引起不耐受症状的发生率不同,早餐空腹饮牛奶者不耐受发生率27.6%(27/98),午餐或晚餐饮牛奶者13.7%(13/98),两者的差异有统计学意义。结论食物种类和不同饮奶方式对牛奶不耐受症状有明显影响,建议不要空腹饮奶,而在正餐饮牛奶,并注意与高蛋白膳食、固体食物搭配,不要与含膳食纤维高的食品(如全麦面包)一起食用。
Objectives To find a diet to improve milk intolerance measures. Methods Hydrogen breath test was used to screen 8 lactose intolerant individuals with watery diarrhea from 38 subjects and to participate in the milk drinking test with different foods designed by orthogonal experiment and 25 g milk powder. Cluster sampling method Select 100 healthy college students to participate in different ways of 25 g milk powder in milk test to observe the symptoms of intolerance after drinking milk test. Results The subjects’ ability to drink milk and intake of eggs, steamed bread, pot kui and bread after the expiration were lower than those of drinking milk alone (both less than 1.786 mg / m ~ 3). Orthogonal analysis and ANOVA showed that : Chicken stock and milk mixed with stool lactose and symptom score than the bread and milk mixed with low, the difference was statistically significant. Whole wheat bread and milk mixed with the highest symptom score; different ways of drinking milk caused by the incidence of intolerance symptoms are different, breakfast fasting drink milk were intolerant rate of 27.6% (27/98), lunch or dinner drinking milk who 13.7% (13/98), the difference between the two was statistically significant. Conclusions Food types and different ways of drinking milk have obvious effects on milk intolerance symptoms. It is not advisable to drink milk on an empty stomach. When you are drinking milk and paying attention to high-protein diet and solid food, do not mix with foods containing high dietary fiber Such as whole wheat bread).
