Bloating: What Does the Latest Research Actually Tell Us?

Q: Bloating is normal, right?

Wrong. For years, we've been told that bloating is simply "normal", something to put up with, or that the answer is to eliminate more and more foods. Fortunately, the latest research paints a very different picture.

Q: Should You Cut Out Gluten or Dairy?

One of the clearest messages from recent guidelines is: don't remove foods unless there's a good reason. Unless you have coeliac disease, a diagnosed allergy or a clear intolerance, unnecessarily avoiding entire food groups may actually reduce the diversity of your gut microbiome over time.

Why Am I Bloated? Natural Solutions.

'I've tried cutting out gluten, dairy, taking probiotics, drinking peppermint tea… so why am I still bloated?'

If this sounds familiar, you're certainly not alone. Bloating is one of the most common reasons people seek my support, and yet it's also one of the most misunderstood digestive symptoms.

Bloating is normal, right?

Wrong.

For years, we've been told that bloating is simply "normal", something to put up with, or that the answer is to eliminate more and more foods. Fortunately, the latest research paints a very different picture.

Rather than searching for one miracle food or supplement, scientists are increasingly recognising that bloating is highly individual. The key isn't finding a quick fix—it's understanding why your body is bloating in the first place.

Let's take a look at what the latest research from the past two years tells us.

Bloating is a Symptom, Not a Diagnosis

One of the biggest shifts in digestive health research is the recognition that bloating is rarely the problem itself.

Instead, it is often a sign that something else needs attention, such as:

An imbalance in the gut microbiome
Poor digestion of certain carbohydrates
Constipation or sluggish bowel movements
Irritable Bowel Syndrome (IBS)
Food intolerances
Hormonal changes
Stress affecting the gut-brain connection

This is exactly why I don't believe in one-size-fits-all nutrition plans. Two people can experience identical bloating for completely different reasons, which means their solutions are often different too.

Is the Low-FODMAP Diet Still the Gold Standard?

In short—yes, but with an important caveat.

The low-FODMAP diet continues to have the strongest evidence for reducing bloating in people with IBS. However, researchers now stress that it should never become a lifelong restrictive diet. And this is exactly the approach I take in my nutrition clinic.

FODMAPs are naturally occurring carbohydrates found in many healthy foods. For some people experiencing digestive distressor with IBS, certain FODMAPs can be poorly absorbed and contribute to symptoms such as bloating, wind, abdominal pain and changes in bowel habits.

If this is you, the goal is not to remove every FODMAP food forever, but to identify which foods your body struggles with while keeping your diet as varied and nourishing as possible

Instead, it's designed to be a short-term investigation.

There are approximately 100–200 commonly identified FODMAP-containing foods, and when different varieties and preparations are included, this number can easily exceed 300. This highlights the importance of identifying your individual triggers, as FODMAP sensitivity is highly personal. Attempting to avoid all FODMAP-containing foods would be unnecessarily restrictive, nutritionally challenging, and unlikely to reflect your specific tolerance levels.

The process involves:

Tracking your symptoms for a period ofd weeks to help identify problematic foods.
Removing these problematic and sometimes higher-FODMAP foods for a few weeks.
Allowing symptoms to settle
Gradually reintroducing foods to identify your individual triggers and most importantly tolerance levels.

The aim isn't to avoid healthy foods forever. It's to build the most varied diet your body comfortably tolerates.

More Fibre Isn't Always Better

For years we've heard the advice to simply 'eat more fibre'.

The latest evidence shows it's not quite that simple.

Different fibres behave very differently inside the gut.

For many people experiencing bloating, soluble fibre such as psyllium can support regular bowel movements without creating excessive gas.

In contrast, increasing large amounts of wheat bran or other insoluble fibres too quickly may actually worsen bloating in some individuals.

This is another reminder that nutrition isn't just about how much—it's about choosing the right type for your body. In my handbook, IBS Unlocked, I look at how to apporach fibre for different types of digestive issues and give you suggestions on how to include it in your diet.

Probiotics: More Isn't Necessarily Better

Walk into any health shop and you'll find shelves full of probiotic supplements claiming to support digestion. As a nutritonal therapist, I find it a dizzying prospect to wade through them all!

The latest research suggests the picture is far more nuanced.

Scientists now believe that probiotics should be selected based on the specific bacterial strains they contain, rather than simply choosing the product with the highest number of billions of bacteria.

Some strains of Bifidobacterium and Lactobacillus appear helpful for certain people with IBS, but there is still no universal probiotic that works for everyone.

If you've tried several probiotics without success, it doesn't necessarily mean probiotics don't work—it may simply mean they weren't the right strains for your gut.

Your Gut Microbiome Could Explain Why Different Diets Work for Different People

Perhaps the most exciting area of current research is personalised nutrition.

Researchers are discovering that each person's gut microbiome processes food differently. This helps explain why one person can comfortably eat onions, garlic and beans while someone else experiences significant bloating after just a small portion.

In the future, dietary advice is likely to become increasingly personalised rather than relying on generic elimination diets.

It's an exciting development and aligns perfectly with the functional nutrition approach of treating the individual rather than the symptom.

Should You Cut Out Gluten or Dairy?

One of the clearest messages from recent guidelines is: don't remove foods unless there's a good reason.

Unless you have coeliac disease, a diagnosed allergy or a clear intolerance, unnecessarily avoiding entire food groups may actually reduce the diversity of your gut microbiome over time.

Instead of guessing, it's far more effective to identify your own triggers through a structured approach.

So, What Should You Do If You're Constantly Bloated?

If bloating has become part of your everyday life, it's worth asking why rather than simply trying another supplement.

The latest research supports a personalised approach that may include:

Identifying your individual food triggers rather than eliminating foods unnecessarily.
Supporting healthy bowel habits.
Choosing the right type of fibre.
Addressing stress and the gut-brain connection.
Looking at gut health as a whole rather than focusing on one symptom.

Most importantly, persistent bloating shouldn't simply be accepted as 'normal'.

Your body is trying to tell you something, and understanding the root cause is often the first step towards lasting relief.

Final Thoughts

The science is moving away from restrictive diets and towards personalised nutrition, and that's something I fully welcome.

There is no single 'anti-bloating diet' that works for everyone.

Instead, the evidence continues to support identifying your triggers, supporting your gut microbiome, and creating a sustainable way of eating that works with your body—not against it.

If bloating is affecting your confidence, comfort or quality of life, remember that you don't have to navigate it alone. With the right investigation and a personalised approach, lasting improvements are possible.
