Kate Middleton recently shared her favorite food, which surprised many people.

The British Royal family is known for having strict rules about food.

Offal, including kidneys, is a less popular food choice these days.

Middleton surprised people by saying she loves kidneys, which is considered a humble meal in history.

Offal dishes were created to utilize cuts of meat that were usually discarded by butchers.

Classic British fare includes dishes like steak and kidney pie and devilled kidneys.

Middleton's love for offal is keeping the legacy of classical English cooking alive.

Middleton bonded with a 109-year-old woman over their shared love for brussels sprouts and kidneys.

Middleton's surprising admission challenges the perception of what royals typically eat.
