Answer to Question 1

B
Feedback:
Various factors complicate the study of trace minerals. They include high variability of trace mineral content, food composition data are not available for all trace minerals, bioavailability varies within the context of the total diet, and reliable and valid indicators of trace elements status are not available.

Answer to Question 2

1, 2, 4
Rationale: Caffeine is the most widely used central nervous stimulant in the world and can adversely affect blood pressure. Foods with a high sodium content such as ham, potato chips, and bacon also cause an elevated blood pressure by decreasing the amount of water eliminated in urine. Ice cream and bananas would not affect blood pressure.
