Celebrity chef Jamie Oliver has promoted Veganuary to his 7 million followers on Twitter.
The famous foodie took to social media to share plant-based recipes with those taking part in the annual event.
Veganuary, which encourages people to try veganism throughout January, has a record number of sign-ups this year – with more than 135,000 people so far taking part.
The chef tweeted: “Giving #Veganuary a go this January or just cutting back a bit on meat and dairy after the festive period?
“We’ve got masses of tasty vegan recipes packed full of the good stuff!”
In a separate tweet, Oliver wrote: “Are you vegan or going vegan for #Veganuary?
“Here’s three great meat-free sources of protein you should include in your diet [nuts , seeds, and beans].”
His tweets provoked a mixed response, with one user asking: “So have you signed up to Veganuary yet Mr. Jamie Oliver?”
While the chef has previously spoken about reducing his meat intake, he is not believed to be vegetarian or vegan.
