The aims of this study were to estimate daily intake of macrominerals from beverages, liquid teas, and liquid coffees and to evaluate their potential health risks for Korean children and adolescents (1-to 19 years old). Assessment of dietary intake was conducted using the actual level of sodium, calcium, phosphorus, potassium, and magnesium in non-alcoholic beverages and (207 beverages, 19 liquid teas, and 24 liquid coffees) the food consumption amount drawn from “The Fourth Korea National Health and Nutrition Examination Survey (2007-2009)”. To estimate the dietary intake of nonalcoholic beverages, 6,082 children and adolescents (Scenario I) were compared with 1,704 non-alcoholic beverage consumption subjects among them (Scenario II). Calculation of the estimated daily intake of macrominerals was based on point estimates and probabilistic estimates. The values of probabilistic macromineral intake, which is a Monte-Carlo approach considering probabilistic density functions of variables, were presented using the probabilistic model. The level of safety for macrominerals was evaluated by comparison with population nutrient intake goal (Goal, 2.0 g/day) for sodium, tolerable upper intake level (UL) for calcium (2,500 mg/day) and phosphorus (3,000-3,500 mg/day) set by the Korean Nutrition Society (Dietary Reference Intakes for Koreans, KDRI). For total children and adolescents (Scenario I), mean daily intake of sodium, calcium, phosphorus, potassium, and magnesium estimated by probabilistic estimates using Monte Carlo simulation was, respectively, 7.93, 10.92, 6.73, 23.41, and 1.11, and 95th percentile daily intake of those was, respectively, 28.02, 44.86, 27.43, 98.14, and 3.87 mg/day. For consumers-only (Scenario II), mean daily intake of sodium, calcium, phosphorus, potassium, and magnesium estimated by probabilistic estimates using Monte Carlo simulation was, respectively, 19.10, 25.77, 15.83, 56.56, and 2.86 mg/day, and 95th percentile daily intake of those was, respectively, 62.67, 101.95, 62.09, 227.92, and 8.67 mg/day. For Scenarios I·II, sodium, calcium, and phosphorus did not have a mean an 95th percentile intake that met or exceeded the 5% of Goal and UL. (Korean J Nutr 2013; 46(1): 50 ~ 60)

The aims of this study were to investigate some macrominerals (Na, Ca, P, K, Mg) in 207 beverages, 19 liquid teas, and 24 liquid coffees. The samples were digested by microwave and determinations of macrominerals were carried out by an Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES). The elements, listed in order of mean value of macromineral content, were potassium 208.4±298.2 mg/L (72.2±169.8 mg/container)> calcium 89.0±161.0 mg/L (26.0±57.7 mg/container)> sodium 71.2±75.0 mg/L (20.9±27.9 mg/container)> phosphorus 55.6±91.9 mg/L (17.9±33.8 mg/container)> magnesium 6.1±18.4 mg/L (2.4±10.1 mg/container). All 250 samples contained sodium and potassium, and the detection rate of calcium, phosphorus and magnesium was 88.4%, 93.2%, and 20.4%. The mean ratio of phosphorus to calcium in beverages, liquid teas, and liquid coffees was 4.2±16.0 (ND~164.4), and sports drinks showed the highest mean ratio (48.5±75.6) significantly (p<0.05). In case of sodium, detected content exceeding labeling regulations (less then 120%) was observed in 12 samples (5.5%).
