Cherries
Cheddar cheese
Chicken
Fresh fish
The Correct Answer is B
A. Cherries do not contain tyramine, which is the compound of concern for clients on MAOIs, so they can be included in the diet.
B. Cheddar cheese is high in tyramine, which can lead to hypertensive crises when consumed by clients taking MAOIs. Therefore, it should be eliminated from the diet.
C. Chicken is generally safe for clients on MAOIs as it does not contain significant amounts of tyramine.
D. Fresh fish is also safe to consume while on MAOIs as long as it is fresh and not aged, fermented, or spoiled, which could contain higher tyramine levels.
