Intake of fermented foods and aged cheeses needs to be avoided in individuals taking monoamine oxidase inhibitors (MAO inhibitors) because of:
  1. Decreased intestinal absorption of pyridoxine
  2. Disruption of the NADPH cytochrome pathway
  3. Potential interaction between epinephrine and pressor amines
  4. Increased urinary excretion of calcium
Explanation
Answer: C - Intake of fermented foods and aged cheeses needs to be avoided in individuals taking MAO inhibitors because of potential interaction between epinephrine and pressor amines. Fermented foods and aged cheeses are high in pressor amines such as tyramine. MAO inhibitors block the action of enzymes that deaminate tyramine, leading to interactions with epinephrine that may cause hypertension.
