A look into the contents of these drinks show that all of them offer a variety of vitamins and minerals. As such, you should consume whichever drink you like best because they're all high in iron! The difference, however, is how much content one would need to drink for it to be "high" in iron. For example, 100 ounces (cups) of tea could provide up to 61% DV (Daily Value) for Iron. On the other hand: 140 ounces (cups) of orange juice also provides up to 61% DV for Iron. So as long as the individual likes either tea or oranges then those specific drinks can be considered high-iron foods!
