Histamine Well Podcast: Exploring Histamine, Methylation & Holistic Health

Could your gut help explain why you’re reacting to foods you once tolerated?
In this episode of The Histamine Well, Joanne explores the connection between gut health and histamine intolerance, explaining how the microbiome, intestinal lining, immune system, and nervous system interact.
A low histamine diet may help reduce symptoms, but what happens when the gut itself is contributing to your histamine burden? Joanne discusses SIBO, dysbiosis, histamine-producing bacteria, mast cells, and the DAO enzyme—and why understanding the underlying contributors matters.
What you’ll learn:
How the intestinal barrier and secretory IgA help protect your gut.
Why microbial diversity, butyrate and immune tolerance matter.
How SIBO, dysbiosis and intestinal inflammation may contribute to histamine symptoms.
How mast cells and certain gut bacteria produce histamine.
Why intestinal health matters for DAO, the enzyme that helps break down dietary histamine.
How stress, the nervous system, and gut motility can influence digestive symptoms.
Why gut support needs to be personalised to your symptoms and tolerance.
Whether you’re navigating histamine intolerance yourself or supporting patients in clinical practice, this episode offers a clearer understanding of the gut–immune connection.

A low FODMAP diet is often used to reduce bloating, so why might your symptoms get worse after starting one?
In this short Q&A episode, Joanne explores three possibilities: eating more sulfur-rich foods, replacing wheat with higher-oxalate ingredients, and changes in gut motility, including the migrating motor complex. She explains why it’s worth looking at what has changed in your diet instead of simply pushing through worsening bloating.
In this episode:
How food swaps on a low FODMAP diet may increase your sulfur or oxalate intake
Symptoms Joanne suggests watching for alongside bloating
Why the migrating motor complex may matter when bloating persists
Why a SIBO test can help clarify what may be going on

In this episode of The Histamine Well, Joanne is joined by clinical nutritionist Melanie Peers to explore circadian rhythm: the daily cycle that helps coordinate sleep, energy, hormones, digestion and immune activity. They also discuss why histamine symptoms may feel worse at certain times of the day or night.
Joanne and Melanie talk about the signals that can disrupt your body clock, from spending the day indoors to bright lights, screens and late meals at night. They share practical ways to support a more consistent rhythm, including morning daylight, time outdoors during the day and a darker evening routine.
In this episode, you’ll learn:
What circadian rhythm is and why it matters beyond sleep
How light and darkness influence cortisol and melatonin
Why meal timing may matter for digestion and gut motility
How histamine activity follows a daily pattern
Simple ways to support your body clock within your routine
If you’re navigating histamine intolerance, sleep difficulties, hormone concerns or persistent gut symptoms, this conversation offers another piece of the picture to discuss with your healthcare practitioner.

NAC can support glutathione production, respiratory health and biofilm disruption—but some people experience nausea, headaches, brain fog, fatigue or bloating after taking it.

In this Q&A episode, Joanne explains how reactions to NAC may be connected to sulfur intolerance, hydrogen sulfide production, gut dysbiosis, biofilm disruption and sensitivity to its mucolytic effects.

You’ll also learn why feeling worse doesn’t necessarily mean NAC is working—and why a lower dose, slower introduction or different approach may be needed.

Why do SIBO, Candida, and other gut infections sometimes return—even after treatment initially seems successful?
In this episode of The Histamine Well Podcast, Joanne explains how biofilms may contribute to persistent bacterial and fungal overgrowths. Biofilms are organised microbial communities surrounded by a protective matrix that can help microorganisms survive antimicrobial treatment and resist immune defences.
Joanne explores the role biofilms may play in recurring SIBO, Candida overgrowth, gut dysbiosis, chronic sinus infections and MARCoNS. She also explains how bacteria and fungi can communicate, share resources and coexist within mixed-species biofilms.
You’ll discover:
What biofilms are and why microorganisms create them
Why SIBO, Candida and gut infections may keep returning
How biofilms can protect bacteria and fungi
The connection between biofilms, chronic sinus infections and MARCoNS
How Candida and Aspergillus form fungal biofilms
The difference between mould, mycotoxins and biofilms
What the biofilm matrix is made from
How enzymes and N-acetylcysteine may support biofilm disruption
Why biofilm support should be introduced gradually during antimicrobial treatment
If you’re dealing with recurring digestive symptoms or want to better understand persistent microbial overgrowths, this episode offers a clear and practical introduction to biofilms and their potential role in gut and sinus health.
