[gotcha] Recommending grapefruit juice as a healthy dietary addition for users on certain medications

When a user mentions taking statins \(e.g., simvastatin, atorvastatin\) or certain blood pressure meds, explicitly warn against consuming grapefruit or grapefruit juice due to CYP3A4 inhibition.

Journey Context:
Grapefruit is universally considered a healthy breakfast item. However, it contains furanocoumarins that irreversibly inhibit CYP3A4 enzymes in the gut. This can cause massive, unpredictable spikes in the blood levels of certain statins, leading to rhabdomyolysis \(muscle breakdown and kidney failure\). The trap is that a healthy food becomes toxic when combined with common prescriptions.
