They’re not the same thing. Not even close.
We hear it a lot: people use “fermented” and “pickled” interchangeably. And we get it -both involve jars, both involve vegetables, and both result in something tangy and delicious.
But under the lid? They’re doing very different things.
Let’s start with pickling
Pickling is fast. That’s the appeal.
You take your vegetables, submerge them in an acidic liquid, usually vinegar, and that acid does the heavy lifting. It drops the pH quickly, preserving the food and giving it that sharp, punchy flavour.
Job done. Shelf-stable. Ready quickly.
The catch? That acid comes from outside the food. Nothing alive is happening in the jar. No bacteria are developing, no cultures are growing. It’s preservation by chemistry, not biology.
Which is fine, pickled things are delicious. But they’re not doing much for your gut beyond tasting good.
Now, fermentation
Fermentation is slower. And that slowness is exactly the point.
Instead of adding acid from outside, fermentation creates it from within. You salt the vegetables, and that salt draws out their natural juices. Those juices become a brine and in that brine, naturally occurring bacteria (lactic acid bacteria, to be precise) get to work.
They consume the sugars in the vegetables and produce lactic acid as a byproduct.
That lactic acid is what preserves the food. That lactic acid is what gives fermented foods their characteristic tang.
But here’s the key difference: the bacteria don’t disappear once the job is done. They stay in the jar. They stay alive. And when you eat the food, you eat them too.
That’s what makes fermented food a living food.
Why living matters
Your gut is home to trillions of bacteria - a whole ecosystem that influences everything from digestion to immunity to how you feel day to day.
Fermented foods feed that ecosystem. Every forkful of kimchi or sauerkraut delivers live, active bacteria directly to your gut - bacteria that have been doing their thing for thousands of years in human diets.
Pickled foods, for all their crunch and flavour, can’t do that. The vinegar that preserves them also ensures there’s nothing alive left to deliver.
It’s the difference between eating a probiotic and eating something that just tastes like one.
Why we ferment at Loving Foods
We didn’t stumble into fermentation by accident. We chose it because we believe in what it does.
Every jar we make is unpasteurised and alive. We don’t heat-treat our products (which would kill the bacteria), and we don’t add vinegar to speed things up. We let the fermentation process run its course, the way it has for centuries.
What you get is a food that’s genuinely doing something.
Our kimchi, for example, contains live lactic acid bacteria including Leuconostoc mesenteroides, a strain now being studied for how it interacts with microplastics in the gut. We didn’t add it. We couldn’t add it. It develops naturally through fermentation, because that’s what real fermentation produces. Read more about it here.
No shortcuts. No speed runs. Just vegetables, salt, time, and the remarkable things that happen when you let nature get on with it.
So, in simple terms
Pickling preserves food using acid added from outside. It’s quick, it’s tasty, and it’s done.
Fermentation creates its own acid from within and leaves behind a community of live, friendly bacteria that your gut actually benefits from.
One is a method of preservation. The other is something much more interesting.
An easy place to start
You don’t need a complicated routine to start getting the benefits of fermented food.
A small spoonful of kimchi or sauerkraut alongside your meals is enough to begin feeding your gut live, friendly bacteria on a regular basis. Simple, tasty, and good for you.
That’s always been the idea.
