Titled Football Going Vegan, the documentary airs on BBC One on October 20 at 23.15 - and is already available to watch on iPlayer.
A 'controversial subject'
"With so many sportsmen and women adopting a plant-based diet, we go on a journey with Jermaine Jenas as he delves deeper into the somewhat controversial subject," the documentary's description reads.
"He speaks to celebrity nutritionist Rhiannon Lambert, cooks a couple of dishes with Instagram chef Miguel Barclay, whilst also spending the day at the first-ever vegan football club, Forest Green Rover."
The benefits of veganism
Jenas also attempts to incorporate a 'vegan lifestyle' into his family life - and 'goes head to head' with prolific animal-rights activist Ed Winters (Earthling ED).
On Twitter, Jenas said the documentary also features footballer Chris Smalling, and explores why he 'switched to veganism and the benefits he has experienced'.
