摘要：The aim of the study was to assess the role of fruit drinks in daily diet of Osijek inhabitants. A special questionnaire was administered to 199 patients visiting a family physician’s office during December 2003. The concentration of vitamin C (L-ascorbic acid) was determined in 42 commercially available fruit drinks. Only 11% (22/199) of study subjects did not take fruit drinks. The mean concentration of vitamin C in all samples was 150.10166.83 mg/L. The questionnaire revealed that 89% (177/199) of study subjects using fruit drinks were taking a mean of 0.4 L of fruit drink per day, yielding a mean of 60.04 mg of vitamin C, i.e. 100% of the recommended daily allowance of 60 mg. Study results indicated fruit drinks to be a significant source of vitamin C in daily diet, however, great variation in vitamin C intake according to socioeconomic status of study subjects and type of fruit drink should be noted.
