Daily intakes of manganese, copper, zinc and cadmium by New Zealand women

Abstract

1. A total of 179 duplicate diets were collected by twenty-three women consuming their habitual diet. Twelve of the subjects were living in a residential hall for students, the others were living in their own homes or in flats. Collection periods varied from 3 to 21 d. 2. Average daily intakes were: manganese 2-7 mg; copper 1-5 mg for diets not containing liver, 7-6 mg for fifteen diets containing liver; zinc 10-0 mg; cadmium 21 microgram for diets not containing liver, 27 microgram for fifteen diets containing liver. 3. The intakes were compared with values for adults from other countries and with current recommended dietary allowances or estimated minimum requirements. Mn intakes were typical for non-vegeratian Western diets. Cu and Zn intakes may have been marginally low. The intakes of Cd were low. 4. Daily intakes of protein (71 g), fat (83 g), fat (83 g), carbohydrate (224 g) and energy (8-1 MJ) from 129 of the diets were similar to recent values obtained for New Zealand women. 5. Subjects living in the residential hall had higher intakes of all nutrients than subjects living in their own homes or flats.

Arsenic and heavy metal concentrations in surface soils and vegetables of Feni district in Bangladesh

“…i.e; equivalent to the average weekly estimated intake of ∼87 mg which is higher than the values in Samata, Bangladesh: 25 mg (Islam et al 2000), in New Zealand: 81.2 mg (Guthrie and Robinson 1977), in Denmark: 81.9 mg (Bro et al 1990); but lower than that in Belgium: 92.4 mg (Buchet et al 1983), in France: 98.0 mg (Biego et al 1998).and in India: 33.6 mg (Tripathi et al 1997). Our determined value is also higher from the reference intake of 66.5 mg for men and 50 mg for women (Chowdhury et al 1993) and the recommendation of dietary allowances (RDA) The mean concentration of Cr in vegetables in order of their levels are: Dagon Bhuyia (33.84 mg/kg −1 ), Feni Sadar (27.37 mg/kg −1 ), Sonagazi (25.89 mg/kg −1 ), Pulgazi (25.28 mg/kg −1 ) and Parsuram (23.31 mg/k −1 ).…”

A Historical Review of Progress in the Assessment of Dietary Zinc Intake as an Indicator of Population Zinc Status

“…The first reports on the Zn content of diets were in the 1960s and 1970s and were based on the analysis of Zn in individual foods (14)(15)(16) or composite diets from a variety of settings (17)(18)(19)(20)(21)(22)(23). Foods of animal origin, especially oysters, meat (beef, pork, veal, lamb) and some seafood, nuts, seeds, dried legumes, and whole-grain cereals were good sources of dietary Zn; vegetables, fruits, and starchy roots and tubers had a lower Zn content, as shown in Table 1.…”

The Risk To Health of Chemicals in Sewage Sludge Applied To Land

“…The major part of the dietary intake appears to come from vegetables, including potatoes and cereals (Friberg et al 1974;Ryan et al 1982;CEC 1978). Dairy products and meat are minor sources, except for liver and kidneys (Guthrie & Robinson 1977), whereas shellfish may contain relatively high concentrations of cadmium (Sharma et al 1983).…”
