The positive influence of healthy eating on prisoners’ after-jail lives is something Vincent often cites when explaining her campaign to naysayers.

“The more you learn about the prison system, the more you learn that the sole aim [should be for prisoners] to be rehabilitated, leave prison and not commit the same crime again,” she says. “Health and wellbeing is a really big part of rehabilitation, and therefore what people are eating is a really big part of rehabilitation.

“If we want these people to come out and not offend again, we’ve got to acknowledge the importance of their health and emotional and mental wellbeing – and that means eating decent food.”

Vincent is the first to admit that she isn’t the kind of person you’d expect to find working in prison reform: she’s creative, she’s young, she’s female. “In my personal life, my friends would not describe me as a serious person,” she says. “I like to party, I like to go out and have a laugh and – unfortunately – there is a well-worn stereotype that if you’re an activist then you can’t be a fun, light-hearted woman either.”

But, she says, she’s learnt to push back against that stereotype.

“Why can’t I spend my days talking about a serious subject and standing up for men locked in cells before spending my evenings dressing up, dancing and drinking margaritas?” she asks. “As a woman in 2018 you don’t have to be one or the other. You can be both, be completely yourself and embrace the variety that this inevitably brings to your life as well.”
