[gotcha] Recommending potassium-rich foods or salt substitutes to someone on ACE inhibitors or ARBs without checking their medication list

If a user is on ACE inhibitors \(ending in -pril\) or ARBs \(ending in -sartan\), advise AGAINST using low-sodium salt substitutes or excessive potassium intake, as these drugs reduce potassium excretion, risking hyperkalemia and cardiac arrest.

Journey Context:
'Eat less salt, use a substitute' is standard heart health advice. However, for patients on ACEi/ARBs, salt substitutes \(which are mostly potassium chloride\) can cause fatal hyperkalemia because the drug already impairs potassium excretion. The intersection of good dietary advice and specific pharmacology is a silent killer.
