Ms. E attended a community health fair where she entered her recalled intake for the previous 24 hours into a computer for analysis. On the basis of the printout she was given, she now thinks she should begin taking vitamin and mineral supplements. A friend who is a nurse correctly bases her advice on the following:
A) A 1-day diet recall offers inadequate data on which to base supplementation.
B) A hand recalculation should be done to verify the accuracy of the computer printout.
C) The RDAs on which computer programs are based are intended for only the 50% of the population who are obsessed with health.
D) Undoubtedly, the operators of the computer at the fair had a product to sell: "Let the buyer beware."
