The Analysis of Copper, Selenium, and Molybdenum Contents in Frequently Consumed Foods and an Estimation of Their Daily Intake in Korean Adults

Abstract

This study aimed to analyze the amounts of copper, selenium, and molybdenum among trace minerals in foods and to evaluate their daily intakes in Korean adults. Contents of copper, selenium, and molybdenum in 366 varieties of foods commonly consumed by Koreans were analyzed using inductively coupled plasma atomic emission spectrometry and inductively coupled plasma mass spectrometry, techniques with low detection limits as well as high reproducibility and precision. Next, we evaluated the status of trace mineral intake using the 24-h recall method after conducting anthropometric measurements on 249 male and 344 female adults aged 20 or older. The average daily energy intake for males was 7,452.8 kJ, significantly higher than the 6,118.3 kJ for females (p < 0.001). The average daily copper, selenium, and molybdenum intakes by males were 1,156.7, 135.5, and 12.2 microgg, respectively, compared to 1,028.5, 122.9, and 10.1 microg, respectively, by females. In males, the intake levels of copper and molybdenum were both significantly higher than in females. By continuously evaluating intake levels in this manner, it is anticipated that reference intakes of trace minerals will be established.

Molybdenum in Biological Samples and Clinical Significance of Serum Molybdenum

“…Accordingly, Mo intake in these countries is thought to be adequate. The Mo intake of Korean people was estimated to be only 11 mg/day [19]; however, this figure is doubtful because the analytical values adopted in this report were one order of magnitude lower than those of other reports. Since cereals and pulses contain Mo at a very high level, the Mo intake of vegetarians [17] and people who eat a large amount of soybeans [9] is higher than that of the general population.…”

Meat Quality and Physicochemical Trait Assessments of Berkshire and Commercial 3-way Crossbred Pigs

“…Meat products contain energetic minerals that are essential for various biochemical functions in organisms (Bilandzic et al ., 2012; Horita et al , 2011), and low dietary access to mineral elements leads to various human disorders (Melo et al , 2008). In particular, dietary Se, Mg, and K are required for physical functions and these minerals participate in oxidation reduction reactions (Choi et al , 2009). Muscles from two way cross breed of Yorkshire × Large white pigs (Y×LW) had higher Mg, Fe, and Zn contents than those from Large white , and Kanengoni et al (2014) reported that C and P levels were higher in Large white × Landrace pigs than in South African Windsnyer-type indigenous pigs.…”

Copper content of staple seeds and grains grown in Kanam local government area, Nigeria

“…We conducted this analysis using ICP-MS because it was suitable for the analysis of low concentrations without large interference (Choi et al 2009). The ICP-MS was operated at 1,400 W forward power with a coolant flow rate of 13.5 l/min, nebulizer gas flow rate of 1.15 l/min with concentric nebulizer.…”
