Cadmium burden of men and women who report regular consumption of confectionery sunflower kernels containing a natural abundance of cadmium.

摘要: Because of inherent genetic and physiological characteristics, the natural concentration cadmium in kernels sunflowers grown uncontaminated soils northern Great Plains region United States is higher than most other grains. We tested hypothesis that a habitual consumption sunflower will increase body burden health effects humans. Sixty-six men women who reported consuming various amounts were recruited divided by sex kernel consumption: those consumed less or equal to 1 ounce(oz)/week more oz/week. Cadmium intake was assessed calculation from 7-day food diaries, whole blood cadmium, red cell (RBC) urine concentrations, urinary excretion N-acetyl-beta-D-glucosaminidase (NAG) activity beta2-microglobulin (beta2MG). The results showed high intakes (>1 oz/day) significantly increased (p 0.05). normal ranges for these protein markers have not been established, it possible determine if elevated values meaningful. However, given knowledge with concentrations products average dietary potential exists an cadmium. Controlled feeding studies humans should be pursued order does indeed and, so, cause concern.
