Dietary Taurine Intake and Its Food Sources in Korean Young Adults Using 2015 Korea National Health and Nutrition Examination Survey Data.

Abstract

This study aimed to estimate the dietary taurine intake and its food sources in Korean's aged between 19 and 29years. The study included 619 participants (292 males and 327 females) who had provided data via a 24-h recall method to the 2015 Korea National Health and Nutrition Examination Survey (KNHANES). Dietary taurine intake and the sources of dietary taurine were estimated by using CAN-Pro 4.0 software. Statistical analysis was performed by using SPSS 20.0. Average height and weight of the subjects was 174 cm and 73.5 kg in males and 161 cm and 56.4 kg in females, respectively. The prevalence of obesity in males was significantly higher compared to females (p<0.001). Overall, the nutrient intakes of subjects were higher than the dietary reference intakes for Korean's (KDRIs). In particular, phosphorus and sodium intakes of males and females were higher, whereas, potassium and calcium intakes of males and females were lower than the KDRIs. The average intake of taurine 327.3 mg by males was significantly higher compared to 245.1 mg by females (p<0.05). With regard to dietary taurine intake from the main food groups, meat (p<0.001), vegetable (p<0.001), beverages and alcohol (p<0.05), and cereal (p<0.001), in males was significantly higher compared to females. This study showed that 19-29years old Korean young adults had a high intake of taurine due to high intake of protein. However, since high intake of meat can lead to chronic disease, it is necessary to provide nutrition education to increase the intake of fishes and shellfishes as a taurine source food.
