Why Fermented Foods Matter

Winter_Wellness_Darts_Farm_Devon_1200x1200 Fermentation has been part of human culinary culture for millennia, but it’s only with modern science and research that we are beginning to understand more about how these foods actually work and just how complex our relationships with microbial communities really are.

Our ancestors fermented out of necessity - before fridges - transforming cabbages into sauerkraut or milk into yoghurt meant harvest gluts could be stored safely through winter. Today, fermentation offers something just as valuable: a way to step away from ultra-processed foods and back towards slow, seasonal, nutrient-dense eating.

So what do we mean when we talk about fermentation? Microbes such as bacteria and yeasts feed on natural sugars in vegetables, grains or tea, creating acids and bubbles that preserve food and add complex flavour. This process also produces living cultures (probiotics) and beneficial compounds that can support a healthy gut microbiome and reduce low-grade, body-wide inflammation that underlies many chronic diseases, such as heart disease, some cancers, kidney disease, Alzheimer’s and IBS.

There is increasing evidence that regularly eating fermented foods can increase the diversity of gut microbes, which is linked with better digestion, immune function, reduced anxiety and overall resilience. It’s no wonder foods like kefir, kimchi and kombucha are being heralded as “superfoods”.

There’s a lot to know - and even more that we still don’t know - about the human mysteries of fermentation and the microbiota that are an integral part of human health and our food system.

“The more diverse and patient the ferment, the richer the nutrient profile and the deeper the flavour.”

Your Second Brain

The gut is often called the “second brain” because it is lined with nerve cells and communicates constantly with the brain via the microbiota–gut–brain axis. A complex two-way communication network involving your nervous system and your immune system, it plays an important role not only in your digestive health but also in your mental health.

Fermentation Unlocks Nutrition, Which Develops Flavour

Fermentation is nature’s way of unlocking hidden goodness in food. Friendly microbes gently break down ingredients, making vitamins and minerals easier for your body to absorb, while reducing toxicity.

It also creates those delicious tangy, fizzy flavours we love. Nutrition and flavour are inextricably linked in this process, as they arise from the very same microbial activity.

Take a multi-grain sourdough loaf made from a diverse starter. It has greater flavour complexity than a commercial white loaf and is inextricably tied to its nutritional value. Both nutrition and flavour are an expression of the ingredients that made them in the first place, which is why both are more prevalent in food that comes from healthy and diverse farming practices - and that’s true for non-fermented foods too.

Everyday ways to enjoy…

Easy fermented foods to weave into everyday meals include live yoghurt, kefir, raw sauerkraut, kimchi, miso and traditionally brewed kombucha. Give a couple of our favourites a go:

Boo Chi Kombucha Locally brewed, naturally fermented, 100% real and alive. Each bottle is packed with health-boosting benefits and infused with natural herbs and spices for functionality and goodness without the sugar highs.

Bath Culture House Kimchi and Kraut Handcrafted in small batches using fresh, seasonal ingredients. Always raw and unpasteurised. Delicious in a cheese and sourdough toastie!
