Ask most six-year-olds what their favourite snack is they would probably tell you sweets or chocolate.

But not Princess Charlotte - as it appears her favourite snack is much more unusual.

According to her mum the Duchess of Cambridge, the youngster loves olives.

Kate revealed her daughter's favourite foods on a visit to Lavender Primary School in north London in 2019.

Just a year earlier, Kate revealed a parallel between the young royal and herself, as she previously shared her love of olives in 2018

During the visit to the school, she also revealed that she was teaching George as well as Charlotte to cook.

She said that her children love to “make salads and stuff” as well as their signature dish, cheesy pasta.

Kate often speaks of her love of home cooking, including making pizzas with her children which they reportedly "can't get enough of."

When it comes to Prince George, his favourite food is reportedly spaghetti carbonara.

While Prince Louis also likes an unusual food - beetroot.

When filming with Mary Berry for a TV Christmas special in 2019, Kate divulged: "We've got carrots, beans, beetroot – a massive favourite – Louis absolutely loves beetroot."

However, there is one royal who never tells anybody what her favourite food is, and that's the Queen.

And there's a rather good reason why what she likes best is kept so secret.

A royal insider has explained how the Queen doesn't divulge her favourite food before travelling so that she isn't served the same thing everywhere she goes.

As reported by The Express, Gordon Rayner, former royal correspondent for The Telegraph who has covered more than 20 royal tours, said he'd discovered this fact from a royal staff member.

He said: "As one of her staff told me, ‘If she said she had a favourite meal she would never get served anything else.’"
