Serving size, prep, and portion notes for black tea
Black tea looks gentle but carries three separate triggers: it is high in caffeine, high in salicylates and very high in oxalate. The oxalate is the one people miss, and it matters because black tea is one of the biggest dietary sources of oxalate linked to kidney stones. Cup for cup black tea has less caffeine than coffee, but the salicylate and oxalate load is where it can catch out sensitive people.
Watch for
Very high in oxalate, one of the leading dietary sources tied to calcium-oxalate kidney stones, so heavy drinkers are often told to cut back / High in caffeine, though roughly half that of the same volume of brewed coffee, enough to affect sleep or jitters / High in salicylates, a possible trigger if you react to aspirin or salicylate-rich foods / Moderate in nickel, a minor consideration on a low-nickel diet
