orange juice

oranges + ace inhibitors

Oranges and orange juice are rich in potassium, and ACE inhibitors reduce the kidneys' excretion of potassium by suppressing aldosterone. Drinking large daily volumes of orange juice while taking an ACE inhibitor can nudge serum potassium upward. The risk is real but modest for most people; it matters most in those with reduced kidney function, diabetes, or heart failure, or those also taking other potassium-raising medicines or supplements.
