Ever wonder why a glass of wine, aged cheese or even a healthy avocado can trigger a migraine?
[00:06]
The answer may lie in histamine sensitivity,
[00:09]
and understanding it could change the way you look at your migraines forever.
[00:15]
Welcome to Migraine Heroes, a podcast for people living with chronic migraines with years of pain,
[00:22]
misunderstanding and lack of answers. I'm Diane Ducarme. I've helped more
[00:27]
than a thousand people reduce the burden of migraines and feel more in control.
[00:32]
My mission in life? To help a million people. Each episode brings you grounded insight
[00:38]
into what your body might be asking for and what can truly help.
[00:43]
Just to keep you fully supported, this podcast is educational. For diagnosis
[00:49]
or medication, always work with your doctor. Now, take a breath and let's dive in.
[00:56]
In this episode, you will learn why histamine can become a hidden migraine trigger even when
[01:01]
you are eating healthy foods, the five most common reasons why migraines sufferers struggle
[01:06]
with histamine sensitivity and the mechanisms by which they affect you, and simple actions you can
[01:12]
start today to reduce your histamine burden and gain more control over your migraine patterns.
[01:18]
Stay with me till the end, because at the end of this episode, you will discover one
[01:22]
simple action you can implement today that may significantly reduce your overall histamine load.
[01:27]
If you live with migraines, you may know the frustration of feeling like your triggers
[01:31]
make no sense. One day you tolerate a food perfectly well, and the next day the same
[01:37]
food seems to trigger a migraine attack. And you may have been told to avoid wine,
[01:42]
chocolate, fermented foods, tomatoes or aged cheese, but nobody completely explains why.
[01:47]
It can feel exhausting trying to connect the dots. If it sounds familiar, you are not alone.
[01:53]
Many migraine sufferers discover that histamine may be one of the missing pieces of their puzzle.
[01:58]
So, what is histamine? Histamine is a naturally occurring chemical messenger in the body.
[02:04]
It plays an important role in immune function, digestion, neurotransmission and blood vessel
[02:09]
regulation. And under normal circumstances, histamine helps your body respond appropriately
[02:16]
to allergens, to infections and even daily physiological processes. And problems arise
[02:22]
when histamine accumulates faster than the body can break down. Histamine is found naturally in
[02:29]
many foods, especially in fermented foods, in aged cheeses, in wine and alcohol, in smoked meats,
[02:36]
in vinegar-containing foods, in certain fish products. In addition, your immune cells can
[02:42]
release histamine during stress, allergic reactions, infections and inflammation.
[02:46]
So, why does histamine matter for migraines? Research has shown that histamine can influence
[02:53]
migraine mechanisms through multiple pathways. Histamine can dilate your blood vessels,
[03:00]
activate pain pathways, increase your inflammation, influence your neurotransmitters
[03:07]
and affect the trigeminal nerve system involved in migraine attacks.
[03:11]
And there was a landmark review published in the American Journal of Clinical Nutrition that
[03:15]
described histamine intolerance as a condition resulting from an imbalance between accumulated
[03:20]
histamine and the body's ability to degrade it. And additionally, there was research done by
[03:26]
Wanker et al. that found a higher prevalence of reduced histamine degrading capacity
[03:31]
among migraine sufferers. So, why are migraine sufferers particularly vulnerable?
[03:36]
Let's explore five key reasons. The reason number one is the low
[03:41]
diamine oxidase activity. So, diamine oxidase is one of the main enzymes which is responsible for
[03:47]
breaking down histamine from food. So, if diamine oxidase activity is low, histamine can build up
[03:55]
after meals. And several studies have reported reduced diamine oxidase activity in individuals
[04:00]
with migraines. A study in nutrients found a significant proportion of migraine patients
[04:04]
demonstrated diamine oxidase deficiency. And when histamine accumulates, it can contribute
[04:09]
to symptoms such as headaches, flushing, digestive issues, nasal congestion, dizziness.
[04:14]
And for some migraine sufferers, low diamine oxidase may be a major contributor to attacks.
[04:21]
Now, reason number two, the gut barrier dysfunction. Your gut acts as a gatekeeper.
[04:27]
And when the intestinal barrier becomes compromised, often referred to as increased
[04:33]
intestinal permeability, more inflammatory compounds can enter circulation. Research
[04:38]
increasingly links migraine with gastrointestinal dysfunction. A disrupted gut may contribute to
[04:44]
increased histamine production, reduced enzyme function, immune activation, and systemic
[04:50]
inflammation. And so, this is going to create an environment where histamine sensitivity can
[04:54]
completely flourish. Reason number three is a mast cell activation. So, mast cells are immune
[05:00]
cells that store large amounts of histamine. And so, when activated, they release histamine
[05:06]
into surrounding tissues. Stress infections, allergens, hormonal fluctuations, and environmental
[05:11]
exposure can all stimulate mast cells. So, research by Thierry Herides and colleagues
[05:17]
has explored the role of mast cell activation in neuroinflammation and migraine development.
[05:21]
Activated mast cells near nerves and blood vessels may contribute directly to migraine pathways.
[05:26]
And so, for some people, histamine problems are not just coming from food. The body itself
[05:31]
may be producing and releasing excess histamine. Reason number four is hormonal fluctuations. So,
[05:38]
many women notice migraine worsening during menstruation, ovulation, or actually in perimenopause.
[05:44]
And there may be a biochemical explanation for this. Estrogen can stimulate histamine release,
[05:50]
while histamine can promote estrogen production. And this creates a feedback loop. And during times
[05:56]
of hormonal fluctuation, histamine levels may become difficult, more difficult to regulate.
[06:01]
This may explain why histamine-rich foods suddenly become problematic during certain phases
[06:07]
of the menstrual cycle. Now, this is super level two to know this. It requires a very
[06:12]
sort of expert eye. But, you know, if you track your migraines, you might be able to spot those
[06:17]
nuances. Reason five are chronic stress and nervous system overload. So, stress is not just in your
[06:23]
head. Chronic stress is going to activate the sympathetic nervous system and increase inflammatory
[06:29]
signaling throughout the body. Studies show that stress can stimulate mast cells and histamine
[06:34]
release. When your nervous system remains in a prolonged state of vigilance, your histamine
[06:38]
bucket may gradually fill. And then seemingly harmless triggers, like food, poor nights of sleep,
[06:45]
a strong smell, they become the final drug that overflows the bucket and triggers a migraine
[06:50]
attack. And so, this concept is often called the histamine load theory. It's not always one
[06:55]
trigger. It is the accumulation of many small factors over time. Now, traditional Chinese
[07:01]
medicine does not have a concept called histamine per se. Instead, it asks a bit of a different
[07:07]
question. Why does one person eat a tomato, drink a glass of red wine, walk through a field of
[07:13]
flowers, and feel perfectly fine, while another develops a migraine, flushing, itching, brain fog,
[07:20]
or fatigue? And so, the focus is less on the substance itself and more on the body's ability
[07:26]
to accommodate it. Imagine two glasses. One is large and mostly empty, and the other one is already
[07:32]
filled close to the brim. So, pour the same amount of water into both, and only one is going to
[07:37]
overflow. And so, from an Eastern perspective, histamine sensitivity may sometimes resemble this
[07:42]
idea. The food, pollen, wine, or smells is not necessarily the entire problem. It may simply be
[07:48]
the final drop added to a system that was already carrying a significant load. So, a practitioner of
[07:54]
traditional Chinese medicine might therefore spend less time asking, what was the trigger? And more
[08:00]
time asking, why was your system so vulnerable to that trigger today? And many classical Chinese
[08:07]
texts describe health as a state of adaptability, right? A healthy river bends around rocks. A healthy tree
[08:14]
sways in the wind. A healthy body responds to change in weather, food, stress, and environment
[08:19]
without becoming overwhelmed. And when migraines become more frequent, the question often becomes
[08:24]
whether that ability has been reduced. Perhaps sleep has been poor. Perhaps stress has been high.
[08:30]
Perhaps digestion is struggling. Perhaps the body has been running too hard, too dry, too depleted,
[08:36]
or too tense for too long. And the exact same pattern may differ from person to person. But the
[08:40]
common theme is that resilience has narrowed. The system has less room to absorb large fluctuations.
[08:47]
And so, this is one of the reasons why Chinese medicine often places so much emphasis on
[08:51]
seemingly unrelated things such as sleep, emotional regulation, digestion, breathing, daily rhythm, and energy
[08:56]
recovery. The goal is not simply to avoid every possible trigger. The goal is to widen the
[09:02]
river. To increase the body's capacity to tolerate heat, stress, food variations, weather changes,
[09:07]
strong smells, hormonal shifts, and the countless other inputs that life throws at you. Because a
[09:14]
life spent avoiding everything is often a very small life. Since 2019, I was meeting people,
[09:20]
you know, hundreds of people, one at a time, for 90 minutes. And they would say, you know,
[09:24]
I stop doing this, I don't do that, I don't do that, I never eat this, I never eat that,
[09:29]
yet I still have migraines. And it's really, you're making your life smaller. And that's why
[09:34]
we decided, okay, let's just add food. Let's add food and repair the system instead of removing
[09:39]
food. It's a bit, for me, imagine you have an employee and your employee doesn't work really
[09:44]
well. You can either say, I'm going to give you a smaller load of work, or you can give it a bit more
[09:50]
budget and a bit of training, and then it can handle more. And it's the same idea that we have
[09:56]
at Migraine Heroes. Because a resilient system allows you to participate just more fully in the
[10:01]
world. Now, I'm conscious that this can feel a little difficult to fully grasp or to put in
[10:06]
practice. Now, I want to acknowledge an important exception. If you have a true allergy, especially
[10:11]
a severe allergy such as anaphylaxis to peanuts, eggs, or another food, none of this philosophy
[10:17]
applies. This is a medical situation, not a question of resilience or threshold. What we're
[10:22]
discussing today is something different. It's sensitivities, tolerances, and the body's varying
[10:26]
ability to cope with the many inputs of daily life. Interestingly, when we look back at ancient
[10:31]
medical texts, whether from China, India, or even Europe, we find surprisingly few descriptions of
[10:37]
the widespread food and environmental allergies we see today. They may have existed, but they
[10:41]
appear to have been far less common, or at least far less frequently documented. And so the question
[10:48]
for us is not whether allergies are real. They absolutely are. The question is why so many modern
[10:53]
bodies seem to react so strongly to things that previous generations appeared to tolerate a lot
[10:58]
more easily. And that is where the conversation about resilience becomes interesting. So today,
[11:03]
instead of asking what foods should I avoid, try asking what might help my body become more
[11:09]
resilient. Histamine is often the final drop in the bucket that may have already been full from
[11:16]
stress, sleep dehydration, heat over work, or emotional strain. This week, I want you to pay
[11:22]
attention not only to what you eat, but to the days when your bucket feels fuller. Experiment
[11:28]
with one small act of restoration, an earlier bedtime, a nourishing meal, a walk in nature,
[11:33]
a few minutes of quiet, simple slowing down. The goal is not to fear every trigger. The goal is to
[11:39]
make your bucket bigger. And I know this is hard, and we're not going to solve the whole histamine
[11:45]
issue in a single podcast, but I hope it gives you understanding of what's happening inside of
[11:52]
your body linked to migraine and a more philosophical understanding of how can my
[11:58]
body tolerate a bit more. And remember, every small step you take moves you closer to freedom.
[12:05]
You are powerful, you're resilient, and you're not alone. Keep rising, Migraine Hero.
