A royal chef has revealed what ingredient the royal family refuse to eat

One of Diana's former chefs has revealed the one ingredient that they couldn't use while cooking for the royal family.

And it isn't what you'd expect either, there aren't any rules around sizzlers or KFC - who could live without those!

Carolyn Robb spoke about how they weren't allowed to use garlic at all for her 11 years in the palace from 1989 to 2000.

She said that it may have changed since, but because of the reasoning, she highly doubts it.

Apparently the family couldn't have garlic because of how busy their social schedule is.

No one would want to meet the royal family, and be greeted with horrific garlic breathe, so they simply don't eat it.

Makes sense!
