Why Food Triggers Histamine Symptoms
What is it about the foods we eat that cause histamine symptoms?
You’ve seen a list. Maybe you’ve seen many different lists…
Lists that tell you which foods you should be avoiding because of the histamine flare ups you're getting, in the hope of preventing symptoms like itchy eyes, skin rashes, and a whole host of other unexplained and irritating symptoms.
Yes, it’s easy to think about simply avoiding these foods as a way to reduce your histamine load, but there’s also significant merit in understanding why food can be a trigger.
This understanding will not only help you to make better decisions about the foods that you choose to eat (and decipher those confusing, and sometimes conflicting food lists), but it will also help you to understand the underlying cause of your histamine intolerance, a huge first step towards managing it!
Let me explain…
Getting to know histamine
By now you’re likely aware that histamine is part of a group of chemical compounds in the body called biogenic amines. There are a number of different types of amines, the type of which characterizes the way in which that particular amine group functions in the body.
Histamine is categorized as a monoamine, a simple amine with the primary role of acting as a neurotransmitter, or chemical, that has a mediating response on the brain and spinal cord. When activated, this histamine neurotransmitter causes arousal and a state of heightened attention(1).
Furthermore, histamines are stored in and released from mast cells and basophils, which are two important cells responsible for immunity. These cells release histamine during an allergic reaction, or when tissue damage is present(2).
When it comes to the endogenous, or internal formation, of these biogenic amines, it's a process that occurs through chemical reactions, which alter the state of your body’s amino acid profile. As a quick reminder, amino acids are the building blocks of protein, of which there are 20 that the body needs to function (9) of them can only be obtained through the diet while the other 11 can be made within the body itself(3).
What’s interesting about the creation of these biogenic amines, is that they can be created by metabolic processes that take place within a plant or animal, and what might not be so obvious, is that micro-organisms can synthesize them too(4)!
Do you see where we're going with this?
The problem with food and histamine intolerance
So what's an important link to consider here?... The microbiome, of course! Your gut is home to trillions of these little critters that are able to transform the l-histidine amino acid (found in the food that you consume) into the biogenic amine, histamine(5).
The foods in your diet also contain varying concentrations and strains of bacteria which produce these biogenic amines. When foods begin to spoil, the number of biogenic amines produced by the bacteria increase, which creates an undesirable effect that the food industry works hard to combat!
This is why so many preservatives and other compounds are used in packaged foods, many of which liberate histamine in the body even further... counter-intuitive, don't you think(6)?
What this means, is that your histamine levels can increase not only because of your individual makeup of gut bacteria, but because of the type and age of the foods that are going into your body.
...Don't forget drinks and histamine intolerance
Food isn't the only thing we can put in our mouths that can cause a histamine response. Many of us enjoy the occasional drink to unwind. Unfortunately, when it comes to histamine intolerance, alcohol can do more harm than good.
When you drink alcohol, it not only acts as a histamine liberator because it's fermented(7), and contains histamine-releasing microbes, but it also increases histamine absorption through the intestines and inhibits the effects of DAO(8).
You would be spot on to say that alcohol has three strikes when it comes to histamine intolerance, which is why it’s often recommended to abstain from alcohol completely when you’re trying to reduce your histamine load, even if it’s just for the first few weeks of your intervention. If you do have to drink, try finding a low histamine wine.
Now, these problems don’t only arise in people that are sensitive to histamines; even healthy individuals can develop symptoms of excessive histamine accumulation should they have a particularly high load after consuming histamine-containing foods. When you have histamine intolerance however, even smaller amounts of histamine-containing foods can cause a variety of severe and often debilitating symptoms.
...which is why a low-histamine diet should be the first step towards managing of histamine intolerance, an effective way to improve your quality of life.
The low histamine diet: an easy approach
Hey, remember those lists we spoke about earlier?
It is difficult to decipher which one is “right” for you; but because you’re a unique individual, your reaction to some foods may be worse than it is for others with histamine intolerance.
I’ve created a post that details all of the dos and don’ts to follow when starting the diet. Remember, if you see a symptom reduction within the first two weeks, that is highly indicative of a histamine intolerance. However, this doesn’t mean you should stop the diet after these two weeks! This is just the beginning of a new journey to improving your gut health, and healing your histamine intolerance.
I've put all of this information into a free Guide to Histamine Intolerance that also explains additional ways to identify your food sensitivities, utilize helpful supplements and reduce your symptoms. Click below for the free Guide to Histamine Intolerance!
Don’t worry - the low histamine diet is all-natural, and the options provide more than enough nutrients to keep your body healthy and strong. It even points out healthful foods that actually begin healing your body from the inside out(9).
This is an elimination-style diet to reduce histamine load, which is typically followed for 4-8 weeks with the guidance of your doctor. Once your symptoms dissipate, it’s important to follow a re-introductory phase, that will further increase the variety of foods and nutrient profiles you’re able to give to your body.
Food isn’t supposed to cause you harm, or leave you feeling less than great every single day. When it does, it’s crucial for your overall health and wellbeing to take steps to track down and remove the offenders from your diet. Once you're armed with this information, you will have the power to bring back balance to your system and maintain it long term.
I hope this can be the big first step in your journey to becoming histamine-symptom free!
Life's too short to let symptoms control you.
