Are the symptoms attributed to lactose intolerance really caused by lactose?
Researchers from Barcelona set out to ascertain this in 353 patients, who underwent a hydrogen test. The results show that the symptoms that the patients said they experienced following the consumption of dairy products at home were significantly more severe than those reported during the test, in which the participants were required to ingest 50 g of lactose.
Moreover, the test reveals an ‘over-perception’ of lactose intolerance at home, among both women and men. This study therefore shows that many symptoms are mistakenly attributed to lactose maldigestion.
