Gluten and dairy are two of the most commonly blamed foods in eczema…

But for most people, they are not the root problem.

Here is what is actually happening 👇

1️⃣ Your immune system is overreacting

Eczema is linked to an overactive immune response.

Your gut bacteria play a central role in regulating how your immune system reacts to foods.

2️⃣ Low Bifidobacterium levels can increase reactivity

These bacteria help train your immune system to tolerate harmless triggers.

When levels are low, your response to foods with dairy can become more reactive.

3️⃣ Gut barrier function is compromised

Your gut lining controls what passes into your bloodstream.

When this barrier is disrupted, food components are more likely to trigger immune activation.

4️⃣ Removing foods does not fix the cause

Avoiding gluten and dairy can reduce symptoms in the short term.

But it does not address why your immune system is reacting in the first place.

This is why food lists keep getting longer.

You are managing reactions, not fixing what is driving them.

I’m explaining exactly how this works in my live session on May 6:

Eczema is not just happening on your skin…

It is strongly linked to what is happening in your gut.

Here is what the research shows 👇

1️⃣ Low levels of

Bifidobacterium

This group of bacteria plays a key role in training your immune system.

Lower levels are consistently associated with higher rates of eczema and allergies.

2️⃣ Gut imbalances that can influence the skin

Certain bacteria in the gut can become elevated or out of balance, which may impact how the immune system responds.

For example, higher levels of bacteria like *Klebsiella* have been linked to increased inflammation, which can show up in the skin, especially in eczema-prone or sensitive skin.

3️⃣ Reduced microbial diversity

Children and adults with eczema tend to have less diverse gut microbiomes.

Less diversity means less stability in how the immune system responds.

4️⃣ The gut-skin axis

Your gut bacteria produce compounds that directly influence inflammation in the skin.

If that system is disrupted, your skin becomes more reactive.

This is why creams and topical treatments often give temporary relief.
⠀
They do not address what is driving the immune response underneath.

I’m breaking this down step by step in my live session on May 6:

Mucus is not random.

It is your body responding to something it thinks is a threat.

The problem is not the mucus itself.

It is why your immune system keeps triggering it.

Here is what is actually going on 👇

1️⃣ Your immune system is overreacting

Mucus production increases when your body detects irritation or perceived threats.

This response is regulated in part by your gut bacteria.

2️⃣ Low beneficial bacteria increases sensitivity

Bacteria like *Bifidobacterium* help regulate immune tolerance.

When levels are low, your body becomes more reactive to things like food, pollen, or environmental triggers.

3️⃣ Gut-immune connection drives airway symptoms

Your gut and respiratory system are closely linked through immune pathways.

Imbalances in the gut can show up as symptoms far away from digestion.

4️⃣ You are managing symptoms instead of the cause

Clearing mucus does not change why it keeps being produced.

Without addressing the immune response, it continues.

This is why it keeps coming back.

Your body has not changed how it is reacting.

Seasonal allergies are not just about pollen exposure…

They are about how your immune system reacts to it.

And that reaction is heavily influenced by your gut bacteria.

Here is what is actually happening 👇

1️⃣ Your immune system is overreacting to harmless triggers
Pollen is not dangerous.
But in people with allergies, the immune system treats it like a threat.

2️⃣ Low Bifidobacterium is linked to allergies
These bacteria help regulate immune tolerance.
Lower levels are consistently associated with higher rates of allergic disease.

3️⃣ Gut bacteria control immune balance
Your microbiome produces compounds that help keep your immune response in check.
When this system is disrupted, reactions become exaggerated.

4️⃣ Exposure is not the root issue
You cannot control pollen.
But you can influence how your body responds to it.

This is why symptoms keep getting worse over time.

Your immune system is not being properly regulated.

Pinch-me moment! In the past 3 days .co hosted a summit on the child gut health for over 1500 healthcare practitioners 💥
co brought some of the most-cited scientists and paediatricians in this space with over 1600 publications combined 🔬

It was a dream for me to host Day 1 and interview scientists from Harvard Medical School, Cambridge University, Oxford University, the World Health Organization and Johnson & Johnson - who are all part of our team 🏆

Our scientists spoke about new discoveries on allergy, eczema, constipation and colic - how they are linked to gut health and how they can be reduced or prevented.

One key highlight: in 2025, a study found that 76% of children today are at higher risk of allergy, eczema, asthma and immune conditions ⚠️

We talked about why that is, symptoms to watch out for and how to reduce that risk.

In the past 3 years, .co has not only supported thousands of families - it has also made new discoveries in gut health with the world’s most cited scientists.

More will be shared soon 👀

Most healthcare practitioners are not educated in gut microbiome and nutrition and it’s been an absolute dream to contribute to bridging this gap.

If you’re a practitioner in infant and maternal health, DM me to join our mission.

If you want to learn everything about gut health and how it can be linked to allergies, eczema, constipation and more - comment GUT and I will send you a link to our next webinar.

Most women in perimenopause spend years adjusting their diet, their sleep routine, their skincare...

Getting told this is just what ageing looks like ❤️‍🩹
⠀
But there is a collection of bacteria in your gut specifically responsible for regulating how estrogen circulates in your body.

When those bacteria are depleted, your body loses its ability to manage estrogen properly. Not because your ovaries have failed. Because your gut has lost the tools to do its job.
⠀
Weight that does not shift, skin that changes, and sleep that falls apart… these are not just hormonal, they’re bacterial.

We are covering all of this on May 6 in my FREE gut-first protocol webinar!

You have been told these symptoms are hormonal…

And while some of them are, the gut is driving more of it than most people realise.
⠀
1️⃣ Unexplained weight gain that does not respond to diet or exercise
Your gut bacteria regulate how your body metabolises oestrogen. When that process breaks down, fat distribution changes and metabolism slows in ways that calorie restriction alone cannot fix.
⠀
2️⃣ Sleep that gets worse every year
The gut produces a significant portion of the body's serotonin, which is a precursor to melatonin. When gut bacteria are out of balance, that production is disrupted. Poor sleep in perimenopause is not always hormonal. Sometimes it is bacterial.
⠀
3️⃣ Skin changes and new breakouts in your 40s
Oestrogen supports skin barrier function. But gut dysbiosis drives systemic inflammation independently of hormone levels. Women who address the gut often see skin changes that HRT alone did not produce.
⠀
4️⃣ Bloating that appears or gets dramatically worse in perimenopause
As oestrogen drops, the gut becomes more sensitive and gut bacteria shift. This is not a new food intolerance. It is a microbiome responding to hormonal change, and it is addressable.
⠀
If you are managing these symptoms and not getting answers, the gut is where to start…

"Remedies" that are working against you 👇

- Taking antihistamines every day for months

Antihistamines suppress the immune response at the surface. They do not touch the gut bacteria responsible for regulating that response in the first place. Long-term use addresses nothing and leaves the root cause completely intact.
⠀
- Taking antibiotics at the first sign of a sinus infection

Every course of antibiotics depletes Bifidobacterium, the bacteria that train your immune system to stay calm around harmless triggers like pollen. Each course makes your immune system more reactive, not less.
⠀
- Buying a generic probiotic to "support immunity."

Not all probiotics target immune regulation. Taking the wrong strain does not fix a specific bacterial imbalance. In some cases, it crowds out the bacteria your gut actually needs to produce immune-calming compounds.

- Avoiding the outdoors entirely during pollen season

This does nothing for the gut dysbiosis, making your immune system hyperreactive. Avoidance manages the trigger. It does not address why your body cannot tolerate it.
⠀
Pollen is not the problem...

A gut that cannot regulate your immune response is. We are covering exactly this on April 22. FREE live webinar… the Probiotics Masterclass 🔥

I had severe eczema for years...

I tried everything the wellness industry told me to try. Some of it made things worse. One thing in particular…

A generic probiotic off a supermarket shelf.
⠀
As a molecular biologist who has spent years studying the gut microbiome, this is the one thing you’ll never find in my kitchen.
⠀
Here is what I know that most labels will never tell you 👇
⠀
→ The strain matters. Different bacteria do completely different jobs in the body
→ The dose matters. Most off-the-shelf products do not contain enough to do anything measurable
→ Taking the wrong one is not neutral. It can crowd out the bacteria your gut actually needs
→ Generic does not mean safe. It means untargeted
⠀
Most of what is being sold is not matched to how science actually works. That gap is exactly what we are covering on April 22….

You have tried cutting out gluten, then dairy, then FODMAPs but the bloating keeps coming back…
⠀
That pattern is not bad luck. It is a sign you are addressing the symptom and not what is driving it.
⠀
4 signs your microbiome is the problem 👇
⠀
1️⃣ You bloat regardless of what you eat
If eliminating specific foods never fully works, the issue is not the food. It is the bacterial environment processing it. Research shows that chronic bloating sufferers have significantly lower microbial diversity and distinctly different gut bacteria compared to people without it.
⠀
2️⃣ Your bloating gets worse under stress
Your gut bacteria respond directly to stress hormones. When cortisol rises, microbial diversity drops. That shift changes how your gut ferments food and produces gas.
⠀
3️⃣ You also have irregular bowel habits
Constipation, diarrhea, or unpredictability alongside bloating points to a wider bacterial imbalance, not a single food trigger.
⠀
4️⃣ Your symptoms started or got significantly worse after antibiotics
Antibiotics reduce microbial diversity. Less diversity means less stability in how your gut processes food. This is one of the most common patterns and one of the least discussed.
⠀
Restriction without understanding your microbiome is guesswork...

That is exactly what we are covering on April 22 in my FREE live webinar: The Probiotics Masterclass 🧠
