    Abstract:
    Through the Food and Drug Administration's Total Diet Study, the levels of 11 nutritional elements (sodium, potassium, calcium, phosphorus, magnesium, iron, zinc, copper, manganese, selenium, and iodine) in the diets of eight age-sex groups were determined for the 4 years between 1982 and 1986. The 234 Total Diet Study foods, which are representative of the U.S. food supply, were purchased, prepared for consumption, and analyzed for the elements four times each year. The results were combined with national food consumption data to estimate intakes for 6- to 11-month-old infants, 2-year-old children, 14- to 16-year-old boys and girls, 25- to 30-year-old men and women, and 60- to 65-year-old men and women. Six elements (calcium, magnesium, iron, zinc, copper, and manganese) were low (less than 80% of the Recommended Dietary Allowance or below the low end of the Estimated Safe and Adequate Daily Dietary Intake range) for three or more of the age-sex groups. Six elements were of concern for teenage girls and adult women, five for older women, three for 2-year-old children, two for teenage boys and older men, and only one for infants and adult men. Sodium levels (which did not include discretionary salt) were elevated for 2-year-old children and teenage boys, and iodine was elevated for all age-sex groups. A significant trend was noted only for iodine, the intake of which decreased during the 4-year period.(ABSTRACT TRUNCATED AT 250 WORDS)
