A large portion of the world’s population undergoes a genetically programmed decrease in lactase synthesis and may experience symptoms of lactose intolerance (LI) after dairy consumption. Aim: The aim of the present study was to assess the effect of the same dose of lactose consumed by LI subjects in the form of different dairy products. Material and methods: Fifteen healthy young adults with LI were enrolled in the study. All subjects were symptomatic homozygotes –13910 C/C in the lactase promoter gene. The hydrogen-methane breath test was performed in each subject after a load of 400 ml of milk, kefir and yogurt. Clinical symptoms were assessed within the 12 h after each product consumption. Results: The excretion of gases was lower after ingestion of kefir and yogurt in comparison to milk. All examined subjects reported symptoms. After milk consumption, abdominal pain and intestinal rumbling were perceived as more severe. The number of stools was higher and their consistency was more liquid. Conclusions: Young adults with LI are not able to tolerate the typical dose of different dairy products as assessed by subjective and objective measures. The tolerance of kefir and yogurt is significantly better than that of milk. Streszczenie Wstep: U znacznej cześci ludności świata produkcja laktazy podlega genetycznie zaprogramowanej redukcji, co moze prowadzic do wystepowania objawow klinicznych nietolerancji laktozy (NL) po spozyciu produktow mlecznych. Cel: Ocena wplywu spozycia takiej samej dawki laktozy przez osoby z NL, podawanej w postaci roznych produktow mlecznych. Material i metody: Badaniem objeto 15 mlodych doroslych z objawową NL. Wszyscy badani byli homozygotami –13910 C/C w zakresie genu promotorowego dla laktazy. U kazdej osoby wykonano wodorowo-metanowy test oddechowy po obciązeniu 400 ml mleka, kefiru i jogurtu. Objawy kliniczne oceniano przez 12 godz. po spozyciu kazdego produktu. Wyniki: Wydalanie gazow bylo mniejsze po spozyciu kefiru i jogurtu niz mleka. Wszyscy badani zglaszali objawy kliniczne. Po spozyciu mleka bole brzucha i przelewania byly bardziej nasilone, stwierdzono wiekszą liczbe stolcow, a ich konsystencja byla bardziej plynna. Wnioski: Mlodzi dorośli z NL nie tolerują typowych porcji produktow mlecznych, co potwierdzono w ocenie subiektywnej i obiektywnej. Tolerancja kefiru i jogurtu jest znacząco lepsza niz mleka.
