Functional foods in the diet of people with lactose intolerance

Intolerancija na laktozu javlja kod osoba koje ne mogu probaviti laktozu (mliječni šećer). Postoji više različitih vrsta intolerancije na laktozu: kongenitalna laktoza intolerancija, sekundarna hipolaktazija i primarna intolerancija laktoze. Kod sva tri tipa problematično je konzumiranje mlijeka i mliječnih proizvoda, zbog visokog udjela laktoze. Od funkcionalne hrane koja se koristi u prehrani osoba s intolerancijom na laktozu najzastupljenija su fermentirana mlijeka i proizvodi od fermentiranog mlijeka. Razlog tomu je taj što je u njima dio laktoze preveden u mliječnu kiselinu, pomoću mikroorganizama (probiotika), koji su dodani tijekom njihove proizvodnje. Tako je u fermentiranim mliječnim proizvodima udio laktoze smanjen, a povećan udio mliječne kiseline, čime je olakšana njihova probavljivost.Lactose intolerance occurs in people who can not digest lactose (milk sugar). There are several different types of lactose intolerance: congenital lactose intolerance, secondary lactose intolerance and primary lactose intolerance. In all three types is milk and dairy products consumption presents a problem because of the high lactose representation. Most functional food which is used in the diet of people with intolerance to lactose are fermented milk and products made from fermented milk. The reason for this is that in them is part of lactose converted to lactic acid by microorganisms (probiotics), which were added during their manufacture. Thus, in fermented milk products part of lactose is reduced, but part of lactic acid is increased, what facilitates their digestibility
