Putting bacteria back into our food, one pickle at a time

For millennia, all pickles were living things, home to an invisible mass of microbes. Now they often only live in sterile vinegar - but we need to put the bacteria back, for the sake of our health.

I was recently asked to speak at a friend’s birthday celebrations. Tim being a poet, most of the other guests did a turn in verse. I, however, was asked to riff on the subject of pickles. Party catering came in the form of vinegary vegetables.
 
Tim, you see, is a pickle lover; before I began the research for my talk I might even have labelled him an obsessive. Then I read about America’s small but passionate “fermento” movement. Fermentos believe that pickles are the key to many modern health problems – not just any old gherkins, mind you, but proper pickles: the old-fashioned, traditionally fermented kind. The sort of pickle that’s still alive when you bite into it.
 
For millennia, all pickles were living things, home to an invisible mass of microbes. These microbes were responsible for transforming fresh food into something that would keep for months, even years, through fermentation.
 
The pickles achieved this by converting the sugars in the fresh foods to acids, creating an environment so acidic that no bacteria which were potentially more dangerous could survive. The food was thus preserved almost indefinitely. Three hundred-year-old pickled breadfruit has been found in Fiji in an edible, if not particularly attractive state. As Michael Pollan concedes in his book Cooked: a Natural History of Transformation, “the idea that the safety of a food is guaranteed by the bacteria still alive in it is a hard one for us Pasteurians to stomach”. But every culture has its own fermented speciality, often an acquired taste, because the process often produces very distinctive flavours.
 
It can be hard for the uninitiated to stomach Japanese natto, or fermented soybeans; the same is true of the vinegary Ethiopian injera bread. And Captain Cook fairly had to force his crew to eat sauerkraut to ward off scurvy during a 27-month voyage.
 
As well as the tangy cabbage they could see, Cook’s sailors would have been ingesting all manner of what is called, in probiotic food advertisements, “friendly bacteria”. Yet in the past century what is now a selling point in pricey yoghurt drinks has become the enemy in our diet as a whole.
 
Live yoghurt is the last refuge of the living foodstuff – most “pickles” today are in fact just soaked in sterile vinegar. Even those that are still fermented in the old way, such as kimchi and sauerkraut, are now routinely pasteurised before sale.
 
Fermentos (or “post- Pasteurians”) believe this fear of the microbial world is making us ill – and, though it is unlikely that yoghurt or sourdough holds the key to universal health, there is growing evidence to suggest that, mad as they sound, the fermentos may have a point.
 
Consider that 90 per cent of the cells in our bodies belong to microbes, many of them resident in our digestive system and most of them, if evolutionary theory is to be believed, living there for a very good reason. Though we still know relatively little about the function of the vast majority, studies suggest a diet rich in beneficial bacteria can have surprising benefits, from shortening the duration of children’s colds to relieving the symptoms of asthma and irritable bowel syndrome.
 
It seems that human beings need those microbes as much as they need us, yet we are still doing everything we can to kill them off. The routine use of antibiotics, and our obsession with sterilising everything in sight, from chopping boards to cheese, makes us fail to replenish the microbial crowd within, and neglect to nourish its existing residents.
 
Naturally, only the most deluded fermento would deny that Pasteur’s discovery saves millions of lives worldwide, but in a far more hygienic age it is no longer a universal panacea. We need to put the bacteria back, and if that means fermenting sauerkraut in the shed, then so be it. Perhaps Peter Piper was ahead of his time.

Britain's diversity crisis starts with its writers. Here's why

What happens on the casting couch draws the headline, but the problem starts on the page, says James Graham. 

I’m a playwright and screenwriter, which – pertinent to the issues we’ll be discussing in this enquiry – still feels weird to say. I get embarrassed, still, saying that, in a taxi or hairdressers. I don’t know why I still carry that insecurity about saying I’m a writer, but I do, because it sounds like I’m lying, even in my own head.

Obviously I’m completely biased, and probably overstating the influence and importance of my own profession, but I think so many of the problems surrounding lack of representation in the performing arts start with writers.

If we aren’t encouraging and generating writers from certain communities, classes or backgrounds to tell their stories, to write those roles, then there’s not going to be a demand for actors from those communities to play them. For casting agents or drama schools to prioritise getting diverse actors on stage. We need to create those plays and TV dramas –like the ones that I grew up with. I didn’t have any access to much theatre until I was fifteen, but I did have Boys From the Black Stuff, and I did have Cracker, and I did have Band of Gold. I think the loss of those regional producing bodies – Central, Granada – now all completely centralised into London, means that we just tell less of those stories. I remember a TV show called Boon – anyone? – which was set in Nottingham, and I would see on the TV streets I’d walked down, and think, Oh my God, that actor is walking down a street I’ve walked down. That sounds like it’s insignificant. If you’re from a town that is deprived, that feels ignored, it isn’t.

I was very lucky that at my school (which was, at the time, the largest comprehensive school in the country), from the headmaster down to the drama teachers, everyone just believed that working class kids should do plays. Be in plays, read plays, perform plays to the community. Both inside the curriculum of the school day, and outside it – drama teachers dedicating their time to staying behind. Our head of drama identified a group of us who clearly had a passion for it. We weren’t likely thesps. One lad’s entire family were made unemployed when the pit closed. Many lived on the big council estate. My parents and step-parents worked respectively in warehouses, the local council, or as the local window cleaner (incidentally, my first real job. Which I was terrible at).

Our drama teacher was encouraged and determined enough to launch the first ever Drama A-Level in our school. Based on that, about 10 or 12 of us got the confidence – or arrogance – to take our own show to the Edinburgh Festival. We were 16 or 17, and the first people in our community to ever go to visit the festival. We did a play up there, and after that, a psychological unlocking happened, where I thought: maybe I could do a degree in drama (it was the first time I had ever thought to do so) at university (the first in my family to go. Well, joint-first. My twin sister went on the same day, but I walked into my digs first).

I enrolled in drama at Hull University. A high proportion of my peers were middle class. A higher proportion from London or the South East. They talked often about institutions I had never heard of. They were talking about the National Theatre: I didn’t know we had a national theatre that my parents had been paying tax for that I had never been to. Many had performed with the (again, apparently) ‘National’ Youth Theatre, also in London. Paul Roseby, also on this panel, has made such leaps forward in getting the NYT producing in regional venues, and making auditions possible for people across the UK, but unfortunately, at the time, that wasn’t the case for me – and I was the ideal candidate to be in the National Youth Theatre.

I started writing because I had the confidence after I read texts by people like Jim Cartwright, Alan Bennett, John Godber, Alan Ayckbourn: Northern writers, working class writers that made me think it wasn’t just something that other people do.

After returning home, and working at local theatres, I moved down to London. I had to. The major new writing producers are there. All the TV companies are there. The agents are there. I was lucky to find support in a pub fringe theatre – though the economics meant there was no money to commission, so I wrote plays for free for about four years, that would get produced, and reviewed in the national press, while I worked various jobs in the day and slept for a time on a mate's floor. The first person to ever pay to commission me to write a play was Paul Roseby of the National Youth Theatre. I’m now very lucky to be earning a living doing something I love. In a way, compared to actors, or directors, it’s easier for writers who don’t come from a background that can sustain them, financially, in those early years. Your hours can be more flexible. Yes, it was annoying to miss rehearsals because I had a shift in a call centre, but it was still possible to do it. If you’re an actor or director, you’re fully committed. And if you’re doing that for nothing, there starts to be cut-off point for those from backgrounds who can’t.

I’m sure that local and regional theatres are the key to drawing in talent from less privileged backgrounds. But the range of national arts journalism that cover work outside London has been so significantly reduced. In our little echo chamber a few weeks ago, we theatre types talked about Lyn Gardner at the Guardian. Her coverage has been cut, which is very directly going to affect her ability to cover theatre shows outside of London – and so the self-fulfilling cycle of artists leaving their communities to work exclusively in London takes another, inevitable, turn.

I am culpable in this cycle. I have never done a play at the Nottingham Playhouse, my local producing house growing up – why? Because I’ve never submitted one, because I know that it will get less national press attention. So I just open it in London instead. That’s terrible of me. And I should just bite the bullet and say it doesn’t matter about the attention it gets, I should just go and do a story for my community. And if I, and others, started doing that more, maybe they will come.

I also want to blame myself for not contributing back to the state schools that I come from. I really really enjoy going to do writing workshops with kids in schools, but I would say 90 per cent of those that I get invited to are private schools, or boarding schools, or in the South of England. Either because they’re the ones that ask me, because they’re the ones who come and see my shows in London and see me afterwards backstage, or because they have the confidence to email my agent, or they have the budget to pay for my train ticket. Either way, I should do more. It would have helped the younger me so much to meet a real person, from my background, doing what I wanted to do.

I don’t know how to facilitate that. I take inspiration from Act for Change, creating a grassroots organisation. I know that there is a wealth of industry professionals like me who would, if there was a joined-up structure in place that got us out there into less privileged communities, we would on a regular basis go to schools who don’t get to meet industry professionals and don’t unlock that cultural and psychological block that working class kids have that says, that is not for me, that is something that other people do, I would dedicate so much of my time to it. That’s just one idea of hopefully better ones from other people that might come out of this enquiry.
