Stars back Oliver's food campaign
Celebrity chef Jamie Oliver has teamed up with musicians including Ed Sheeran and Professor Green in his latest campaign.
The star published a video on his Facebook page showing him working on a song in support of his plan for a food revolution day which aims to put food education on the curriculum.
He said: "Ed just came in to do a little bit of filming for me, to support Food Revolution Day. I start telling him a few things, writing a few things down, and then he only went and wrote an anthem."
The video also shows him receiving backing from names including Professor Green, Hugh Jackman, Alesha Dixon and Sir Paul McCartney.
Oliver has also launched an online petition for supporters to back his campaign and wants one million signatures for it.
He said: "We're currently facing a global obesity epidemic, with 42 million children under the age of five either overweight or obese across the world.
"The bottom line is the next generation will live shorter lives than their parents if nothing is done to rectify these alarming stats.
"It's essential that we arm future generations with the life skills they urgently need in order to lead healthier, happier, more productive lives. I passionately believe this is every child's human right and I hope you agree."
As of this afternoon, the petition had gathered more than a million signatures.
