Question

Quizplus · Accepted Answer

The criterion of adequacy used to determine the EAR and RDA for selenium is the amount of selenium that maximizes the activity of glutathione peroxidase, which is a selenium-containing enzyme that protects cells from oxidative damage. Keshan disease and hair loss are both associated with selenium deficiency, but they are not used as the criterion for determining the EAR and RDA. Consumption by a healthy population is used to determine the Estimated Average Requirement (EAR), but it is not used alone to determine the Recommended Dietary Allowance (RDA).
