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.

Paul Auster's 4 3 2 1 is by turns rewarding and maddening – just like life

Auster’s epic new novel of immigration, politics and consciousness is rich but imperfect.

It’s a cliché, or a joke: the immigrant who arrives in the New World from the Old Country, to be greeted by an official who promptly renames him, mishearing the strange tongue that the arrival speaks. Paul Auster’s new novel begins: “According to family legend, Ferguson’s grandfather departed on foot from his native city of Minsk with one hundred rubles sewn into the lining of his jacket, travelled west to Hamburg through Warsaw and Berlin, and then booked passage on a ship called the Empress of China, which crossed the Atlantic in rough winter storms and sailed into New York Harbor on the first day of the twentieth century.”

Ferguson’s grandfather is called Isaac Reznikoff. Another Russian Jew advises him that it will be wiser to give his name as “Rockefeller” to the official. “You can’t go wrong with that.” But when it is his turn, “the weary immigrant blurted out in Yiddish, Ikh hob fargessen (I’ve forgotten)! And so it was that Isaac Reznikoff began his new life in America as Ichabod Ferguson.”

A joke or a fable: the way that so many stories begin in America, the stories of those who sailed past the Statue of Liberty and the words inscribed on its base, words to welcome the tired, the poor, those masses yearning to breathe free. And so Auster, in his first novel in seven years, presents the reader with an Everyman, Ferguson-who-is-not-Ferguson, not the man who stepped off the Empress of China but his grandson, Archibald Isaac Ferguson, the cranky protagonist and hero of this tale.

Ichabod begat Stanley and Stanley begat Archie, who was born, like his creator, in Newark, New Jersey, in 1947. This nearly 900-page epic is a Bildungsroman, though it would be more accurate to call it a Bildungs-Bildungs-Bildungs-Bildungsroman, because Archie’s story is told not once but four times. There are that many versions of the protagonist: in each version, his life takes a different turn, and so everything that follows is altered.

Auster is something of a prophet in exile in his own land. His brand of existentialist postmodernism – in which characters with the author’s name might appear, in which texts loop back on themselves to question the act of writing, in which the music of chance can be heard loud and clear – has sometimes found greater favour in Europe than it has in his native United States. For example, City of Glass, the 1985 meta-detective novel that forms part of The New York Trilogy, will be adapted for the stage here this year.

But City of Glass, like all of Auster’s previous books, is a slender novel. The New York Trilogy as a whole comes in at just over 300 pages. Where much of Auster’s work is elliptical, 4 3 2 1 can be overwhelming, but that is precisely the point. The author creates a vast portrait of the turbulent mid-20th century by giving his protagonist this series of lives. The book is divided into sections that clearly mark which Ferguson we are getting: 1.1, 1.2, 1.3 or 1.4.

Yet there is nothing supernatural about this journey lived and relived, as there was in Kate Atkinson’s Life After Life. The only magic involved is the magic of the novelist’s imagination, which allows both writer and reader to juggle realities as if they were balls in the air.

However, it is not as if one Ferguson is midshipman and another a circus performer, or one a loudmouth and another shy and retiring. The strength of this novel is that Ferguson remains himself while events shift around him, changing the course of his life. Ferguson’s father dies, or Ferguson’s father lives but divorces his mother, Rose. What happens then? Rose is a talented photographer; does she continue her work when Stanley prospers and they move to the suburbs, or does she take up golf and bridge? Ferguson is a good student, always a writer: does he go to Princeton or Columbia? What’s the difference between translating poetry in a Paris attic and working as a journalist for the Rochester Times-Union?

At its best, 4 3 2 1 is a full immersion in Ferguson’s consciousness, which, perhaps, is a consciousness not too far removed from Auster’s. His protagonist’s youth is wonderfully, vividly conveyed. Even if you don’t care about baseball, you’ll come to care about it because Ferguson does. The details of the young Ferguson’s life are carefully and lovingly created: the powder-blue Pontiac that his mother drives, the pot roast and cheese blintzes served at the Claremont Diner in Montclair, New Jersey – and  the floorboards in an old house that creak when two young lovers make their way between their separate rooms in the middle of the night. Auster builds a world of heartfelt, lived-in detail.

But this is a novel of politics, too. Ferguson is a young man during the tumult of the late 1960s, when dozens were killed and hundreds injured during riots in Newark in 1967; when students at Columbia occupied the campus in protest over the war in Vietnam; when young men such as Ferguson could be drafted to fight in that war.

It is in this last third of the novel that the book flags a little, as lists of events tumble on to the page: one paragraph contains the My Lai massacre, the killing of the Black Panther Fred Hampton and the Rolling Stones concert at Altamont. At times, history lessons threaten to overwhelm the narrative, and Ferguson’s story/stories lose the texture and particularity that have made them so compelling. And its ending is abrupt, a tying-up of loose ends that fragments on the final page.

But then lives – real lives – have strange, abrupt endings, too. This is a rich, imperfect book, often rewarding, occasionally maddening. Again, like life, or at least if we’re lucky.

4 3 2 1 by Paul Auster is published by Faber & Faber (880pp, £20)
