What Highly Processed Foods Are Really Doing to Your Gut

Have you ever picked up a packet in the supermarket, turned it over and struggled to recognise half of the ingredients?

You’re certainly not alone.

Over the last few decades, our diets have changed dramatically. Convenience has become king. Ready meals, meal replacement bars, flavoured drinks and snacks have become part of everyday life, often replacing the simple, home-cooked meals many of us grew up with.

But somewhere along the way, we’ve stopped asking one very important question:

Is this actually food?

I don’t believe we need to fear every packaged product or strive for perfection. Life is busy, and convenience has its place. But I do believe our bodies recognise real food, and our gut health reflects the choices we make day after day.

What are highly processed foods?

Not all processing is bad. Freezing vegetables, making yoghurt or drying herbs are all forms of food processing that help preserve nutritious foods.

Highly processed (often called ultra-processed) foods are different.

These products are usually made using ingredients you wouldn’t typically find in a home kitchen. They often contain refined starches, added sugars, industrial oils, flavour enhancers, emulsifiers, colourings, preservatives and stabilisers. Their purpose is to make food cheaper to produce, last longer on supermarket shelves and encourage us to keep eating.

Some examples include:

• Sugary breakfast cereals
• Fizzy drinks
• Flavoured protein bars
• Instant noodles
• Many ready meals
• Packaged cakes and biscuits
• Processed meats with long ingredient lists
• Some flavoured yoghurts and desserts

The issue isn’t simply that these foods are processed, it’s that they often replace the nutrient-rich, traditional foods our bodies have relied on for generations.

Why your gut matters

Inside your digestive system live trillions of bacteria, fungi and other microorganisms, collectively known as the gut microbiome.

Although scientists are still learning exactly how this remarkable ecosystem works, we know it plays an important role in digestion, immune function, metabolism and many other aspects of health.

Like any living community, these microbes depend on what we feed them.

A diet rich in a variety of whole foods generally provides the fibre and nutrients that support a diverse microbiome. By contrast, diets dominated by highly processed foods have been associated with lower microbial diversity and poorer overall health outcomes.

No single meal determines your health. It’s the pattern of eating over weeks, months and years that matters most.

Have we forgotten how to eat?

Sometimes I wonder whether we’ve made eating far more complicated than it needs to be.

Our grandparents didn’t count protein grams on an app or search social media for the latest “superfood.” They simply cooked.

Stocks simmered on the stove.

Soup was made from leftovers.

Vegetables came from the garden or the local greengrocer.

Meals were shared around the table.

Food wasn’t perfect, but it was real.

We’ve become incredibly good at manufacturing food that looks appealing and tastes exciting. Yet many people have never felt more tired, more bloated or more confused about what they should eat.

Of course, many factors influence our health, and we can’t blame everything on processed food. But perhaps we’ve drifted further away from the simple principles that nourished generations before us.

Simple ways to support your gut

Improving your gut health doesn’t have to mean following a strict diet or buying expensive supplements.

Often, it’s about returning to the basics.

Try to:

• Cook from scratch whenever you can.
• Eat a wide variety of vegetables and fruits.
• Include naturally fermented foods such as kefir or live yoghurt if they suit you.
• Choose quality sources of protein.
• Drink enough water.
• Swap highly processed snacks for simple, whole-food alternatives.
• Slow down and enjoy your meals rather than eating on the go.

Small changes made consistently are usually far more powerful than dramatic changes that only last a week.

Where bone broth fits in

Bone broth has been enjoyed across cultures for centuries.

Long before it became fashionable, people simmered bones simply because they didn’t waste food. It produced a nourishing stock that became the foundation for soups, stews, sauces and countless family recipes.

At British Broth Company, we’ve simply brought that tradition into modern life.

We slowly simmer British bones before gently dehydrating the finished broth, making it easy to enjoy whenever you need it. We don’t hydrolyse collagen, and we don’t add fillers, flavourings or unnecessary ingredients.

Bone broth isn’t a magic cure, and we would never claim it is.

But it is one more way to replace highly processed convenience foods with something made from real ingredients using traditional methods.

Sometimes, supporting your gut can be as simple as stirring a spoonful into your morning drink, adding it to a homemade soup or enriching your evening meal.

Small swaps can make a big difference

Rather than focusing on what to remove from your diet, think about what you can add.

Instead of:

• Instant soup → Homemade soup with real bone broth
• Sugary fizzy drinks → Water kefir or sparkling water
• Processed snacks → Cheese, boiled eggs or a handful of nuts
• Artificial stock cubes → Natural bone broth
• Takeaways several nights a week → One extra home-cooked meal

Progress doesn’t have to be perfect.

Every real meal is a step in the right direction.

A return to real food

I don’t think the answer to better health lies in another fad diet or another product promising instant results.

I think it lies in remembering what we’ve forgotten.

Real food.

Simple ingredients.

Traditional cooking.

Sharing meals.

Eating more slowly.

Supporting our bodies instead of constantly fighting against them.

Our gut has looked after us since the day we were born. Perhaps it’s time we started looking after it in return.

At British Broth Company, that’s what we’re passionate about—not chasing the latest health trend, but helping people rediscover the nourishing foods that have stood the test of time.

Because sometimes, the best way forward is to take a step back.
