                                According to USDA data, a 100g serving of raw beef liver contains approximately 5.5mg of iron, while a similar serving of raw calves' liver contains about 4.9mg. This data reveals that beef liver has slightly more iron than its younger counterpart, challenging the misconception that calves' liver is always nutritionally superior.
