Abstract

Cilj rada bio je procijeniti unos esencijalnog elementa kalcija u žena hranom i vodama. Mineralni elementi analizirani su u 43 raznih uzoraka pitkih voda, vodovodnih voda te domaćih i uvoznih mineralnih voda. Izmjerene vrijednosti koncentracije kalcija u vodama upotrijebljene su u procjeni unosa kalcija vodom. U procjeni prehrambenog unosa kalcija rabljen je anketni upitnik za utvrđivanje prosječnog prehrambenog unosa kalcija, tzv. kvantitativni FFQ (od engl. food frequency questionnaire) upitnik. Istraživanjem je obuhvaćeno 186 ispitanica u dobi od 20 do 80 godina, podijeljenih u dvije skupine: mlađe (<30) i starije ispitanice (30 godina). Rezultati kemijskih analiza mineralnih elemenata u vodama uspoređeni su s deklariranim vrijednostima i nađeno je da se većina izmjerenih vrijednosti ne razlikuje više od 20%. Prosječan dnevni unos kalcija hranom i vodom u obje dobne skupine je iznad preporučenih dnevnih vrijednosti unošenja kalcija prema RDA (recommended dietary allowance). Unos kalcija viši od 100% preporučenih dnevnih vrijednosti u mlađoj dobnoj skupini ima 74% ispitanica, a u starijoj dobnoj skupini 54% ispitanica. Prosječan dnevni unos kalcija prema prehrambenom referentnom unosu (DRI) viši je od preporučenih vrijednosti u mlađoj, nego u starijoj dobnoj skupini ispitanica. Vode čine oko 15% prosječnog dnevnog unosa kalcija i u mlađih i u starijih ispitanica. Najveće količine kalcija unose se mlijekom i mliječnim proizvodima.

Abstract (english)

The aim of the study was to assess intake of calcium by food and water. Mineral elements were analysed in 43 samples of common drinking waters, tap waters and domestic and imported mineral waters. Determined values of calcium concentrations were used for evaluation of daily calcium intake from water. Quantitative food frequency questionnaire (FFQ) for estimation of average dietary calcium intake was used to assess dietary intake of calcium. Investigation involved 186 women aged 20 to 80 years, divided into two groups: younger (<30) and older participants (30 years). Analysed values of mineral elements with those declared on original labels were compared. Most analysed values did not differ from declared values, and differences were up to 20%. Average daily intake of calcium from food and water, measured by quantitative FFQ was above recommended dietary allowance (RDA) irrespective of age. Calcium intake over 100% RDA was found in 74% of younger and 54% of older women. According to dietary reference intake (DRI), average daily calcium intake is higher than recommended in younger than in older participants. Average daily intake of calcium through waters was about 15% in both younger and older participants. Dairy products were major source of calcium in daily diet.
