Polyphenols
Tannins and other polyphenols bind plant iron in the gut.
Hurrell RF, Reddy M, Cook JD (1999), Br J Nutr. Black tea cut plant-iron absorption from a meal by 79–94%, peppermint tea by 84%, cocoa by 71%, linden by 52% and chamomile by 47%. Adding milk did not change that.

Iron is from food tables, for the food as eaten, and real foods vary with the cut, the brand and the recipe. Your body takes in a share of it, and a larger share when your stores are low.
