Mom is taking telmisartan for high bp. can she eat banana, avo, salmon, spinach, etc. cause the drug causes hyperkalemia and hyponatremia, right?

Potassium: I haven't found that that class of antihypertensive medications(ARB's), cause hyponatremia and have not caused hyperkalemia unless the patient had kidney disease or was taking potassium supplements or taking other potassium retaining medications like aldactone (spironolactone) or ACE inhibitors. I don't think food intake in normal amounts should promote hyperkalemia but periodic blood work should be ordered anyway
