[gotcha] Recommending grapefruit or grapefruit juice as part of a healthy diet for a patient on statins

Warn against grapefruit consumption when taking statins. Grapefruit inhibits CYP3A4, causing statin accumulation and risk of rhabdomyolysis \(severe muscle breakdown and kidney failure\).

Journey Context:
Grapefruit is universally coded as 'healthy'. AI agents suggesting healthy diets might casually include it. However, grapefruit furanocoumarins irreversibly inhibit intestinal CYP3A4, the enzyme that metabolizes most statins. This causes massive systemic statin accumulation, leading to rhabdomyolysis. The 'healthy food' recommendation silently creates a toxic drug interaction.
