Eat your Christmas tree

The world's top chefs have suggested people eat their Christmas trees instead of throwing them away, as they provide vitamin C and other health and environmental benefits.

The chefs say you can eat "pretty much anything", as long as it is an organic tree.

René Redzepi of Copenhagen's three-Michelin-starred restaurant Noma explained that his restaurant has been using pine needles in food for 20 years.

He said: "Think of it like rosemary: it can be used in almost anything.

Spruce can be used to pickle eggs or vegetables, as well as in drinks and infusions."
