Final answer:
Eating legumes, nuts, and seeds does not trigger pheochromocytoma; the condition is caused by tumors in the adrenal medulla and can be triggered by physical exertion, changes in body position, and labor and delivery.
Step-by-step explanation:
All of the following can trigger pheochromocytoma except d. Eating legumes, nuts, and seeds. Pheochromocytoma is a condition where tumors of the adrenal medulla cause an excessive production of catecholamines, resulting in hypertension. Known triggers for pheochromocytoma attacks include physical exertion, changes in body position, labor and delivery, stress, and certain medications or stimulants (such as nicotine and caffeine). However, there is no evidence to suggest that eating legumes, nuts, and seeds would trigger such an attack.
