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.
