“…Copper intake by subjects of this study exceeded not only 0.6 mg, the EAR of copper required by male and female adults aged 20 or higher, but also the RI of 0.8 mg. The result was similar to daily copper intake levels reported in other studies, such as 0.9 [11] and 1.2 mg [12] in Korea, 1.2 mg [13] in the US and 1.2 mg [14] in Spain, but it was lower than the 1.7∼3.7 mg [9,15,16] in Korea, 1.6 mg [17] in Bangkok and 1.9 mg [18] reported in Canada. The selenium intake by subjects of this study was 128.2 μg, higher than the RI of 50 μg for male and female adults aged 20 or higher.…”

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.

“…However, the lack of relation between vitamin E intakes and plasma concentrations observed in this study could also be related to an inaccurate measurement of vitamin E intakes. The seasonal changes in Cu intakes contrast with the results obtained in the United States, where intakes remained similar all year long (Patterson et al, 1984). Furthermore, no correlation between dietary intakes and serum concentrations of Cu or Zn were found in the United States (Patterson et al, 1984) in contrast with the correlation between copper intakes and serum concentrations found in January and February 1996.…”

Furthermore, no correlation between dietary intakes and serum concentrations of Cu or Zn were found in the United States (Patterson et al, 1984) in contrast with the correlation between copper intakes and serum concentrations found in January and February 1996. The relation between zinc intakes and serum concentrations depended on season and adjustment, suggesting the determining role of factors, ie smoking, energy, protein and alcohol intakes on serum zinc concentrations (Kant et al, 1989;Hashim et al, 1996).…”

Objective: To determine the antioxidant imbalance in healthy Cuban men 2 y after the end of the epidemic neuropathy (50 862 cases from 1991 to 1993) and to evaluate its change over 1 y. Design: Prospective study. Setting: La Lisa health centres (Havana, Cuba). Subjects: One-hundred and ninety-nine healthy middle-aged men were selected and 106 completed the study. Subjects were studied at 3 month intervals over 1 year. Interventions: No invervention. Main outcome measures: An assessment of dietary intake and the determination of blood lipid peroxides (TBARS), glutathione, diglutathione, glutathione peroxidase, superoxide dismutase, vitamin E, carotenoids, copper, zinc and selenium were performed at each period. Results: While dietary zinc, vitamins C and E, carotenoids and fat dietary intakes and blood concentrations were low for adult men compared to international reference ranges, serum TBARS concentrations were high at every period. Some signi®cant seasonal variations were observed. The lowest carotenoids (P`0.002) and vitamin C(P 0.0001) intakes, serum b-carotene (P 0.0001) and luteinazeaxanthin (P`0.05) concentrations, and the highest blood TBARS (P 0.0001) and diglutathione (P`0.001) concentrations were observed at the end of the rainy season (October). This period seemed to pose the greatest risk of antioxidant imbalance. Conclusions: Cuban men still represent a vulnerable population in terms of antioxidant imbalance. A national program of vegetable growing and increase in fruit and vegetable consumption is now evaluated in Cuba.

“…The Panel notes that subjects' usual diet was modified during the collection period in the study by Patterson et al (1984) and that the time was likely to have been too short for a new equilibrium to have been reached, given the half-life of manganese (13-37 days; see Section 2.3.6).…”

Following a request from the European Commission, the Panel on Dietetic Products, Nutrition and Allergies (NDA) derived Dietary Reference Values (DRVs) for manganese. Manganese is an essential dietary mineral which is a component of a number of metalloenzymes involved in amino acid, lipid and carbohydrate metabolism. A specific manganese deficiency syndrome has not been described in humans. The body is able to adapt to a wide range of manganese intakes by regulating both efficiency of absorption in the intestine and the quantity excreted via bile. There are no reliable and validated biomarkers of manganese intake or status and data on manganese intakes versus health outcomes are not available for DRVs for manganese. As there is insufficient evidence available to derive an average requirement or a population reference intake, an Adequate Intake (AI) is proposed. Mean intakes of manganese in adults in the EU are around 3 mg/day. In addition, null or positive balances have consistently been observed with intakes of manganese above 2.5 mg/day. An AI of 3 mg/day is proposed for adults, including pregnant and lactating women. For infants aged from 7 to 11 months, an AI of 0.02-0.5 mg/day is proposed, which reflects the wide range of manganese intakes that appear to be adequate for this age group. The AI for children and adolescents is based on extrapolation from the adult AI using isometric scaling and reference body weights of the respective age groups. Manganese is an essential dietary element for mammals. It is a component of metalloenzymes such as superoxide dismutase, arginase and pyruvate carboxylase, and is involved in amino acid, lipid and carbohydrate metabolism. A specific manganese deficiency syndrome has not been described in humans.Absorption of manganese in the intestine is low (< 10 %). Regulation at the level of absorption appears to be one of the adaptive responses to dietary manganese intake and such regulation allows manganese homeostasis to be maintained over a wide range of intakes. A reduction in the biological half-life of manganese has been observed with increased dietary manganese intakes indicating the role of whole-body turnover rate in manganese homeostasis. Elimination of manganese is primarily via the faeces.The assessment of manganese intake or status using biological markers is difficult owing to the rapid excretion of manganese into bile, to homeostatic mechanisms and to the lack of sensitivity of biomarkers over the normal range of intakes. Therefore, there are no reliable and validated biomarkers of manganese intake or status.Nuts, chocolate, cereal-based products, crustaceans and molluscs, pulses, and fruits and fruit products are rich sources of manganese. The main contributors to the manganese intake of adults are cerealbased products, vegetables, fruits and fruit products and beverages. In the EU, estimated mean manganese intakes of adults range from 2 to 6 mg/day, with a majority of values around 3 mg/day. Estimated mean manganese intakes range from 1.5 to 3.5 mg/day in ...
