Question 5

A 65 year old was buying an iron supplement for her "weak blood." She asked the pharmacist about the highest amount she should take daily.What dietary intake standards could the pharmacist use to provide the best recommendation?

Accepted Answer

The pharmacist should use the Tolerable Upper Intake Levels (ULs) to provide the best recommendation, as this will give them the maximum safe amount of iron intake that the patient can consume without negative health effects. The Recommended Dietary Allowances (RDAs) give minimum amounts of nutrients necessary for health, Adequate Intakes (AIs) are similar to RDAs but are based on insufficient evidence, and Estimated Average Requirements (EARs) give the average requirement for nutrients for individuals based on age, sex, and other factors. None of these would provide the maximum safe amount for the patient.

However, if the calorie deficit continues for an extended period of time or is too severe, the body may also start breaking down muscle protein as a source of energy. Therefore, options A and B are the correct choices, while option C is incorrect. Option D includes all three sources, but not all three are utilized in every situation of low calorie intake.
