FFC ClipBoard: Do you sniffle and sneeze a lot? Are you interested in histamines? I was, so I did a little research.
HISTAMINES AND ANTI-HISTAMINES
“Well, there are an increasing number of vulnerable people who are literally trawling around the internet looking for a “proper” food list, for the “ultimate” food list, for the “best” food list. They are desperate for information and looking for a solution to their health problems. Very understandably, the more desperate they get, the more they will go for desperate measures. I hate seeing them abused!
So what is the “ultimate” food list? Is there such a thing as a “failsafe” food list? No there isn’t!
Here’s the problem with many food lists on the internet and examples of why some of them are just plain wrong. They include:”
“Low-histamine diets can be extremely restrictive and can lead to malnutrition.
Histamine intolerance is poorly understood and difficult to diagnose. There’s no evidence that a low-histamine diet will improve quality of life in the long term if you don’t have a true diagnosis.
The primary benefit of a low-histamine diet is that it can serve as a diagnostic tool.
By eliminating histamine-rich foods from your diet for several weeks (under the supervision of a doctor) and then slowly adding them back in, you can learn more about your individual tolerance to foods containing histamine.
Histamine tolerance varies significantly from one person to the next. When you add histamine back into your diet, you can carefully evaluate which foods trigger uncomfortable symptoms, if any.”
“What Is A Histamine Intolerance?
A histamine intolerance occurs when “accumulated histamine and the capacity for histamine degradation” becomes imbalanced. According to ENT and Allergy, histamine “is ingested via food and stored in nearly all tissues of the body.” It plays an important role, to “keep your organs functioning and body working healthily.”
How common is a histamine intolerance? No one knows for sure, but we do know that “almost 20% of the Westernized world’s population suffers from some type of food intolerance.” The current estimate is that 1-3% of people have a histamine intolerance, but this number may increase as the condition becomes better understood and diagnostic tools become available to medical professionals.”
“Your allergies are an immune response to an otherwise harmless substance. This substance — whether it’s pollen, animal dander, or dust — comes into contact with cells in the mucus membranes of your nose, mouth, throat, lungs, stomach, and intestines. In a person with allergies, this ends up triggering the release of the chemical histamine.
Histamine is a part of the immune system that causes all the symptoms you associate with allergies — the sneezing, itching, and cold-like symptoms you dislike. Antihistamines block histamine activity, seeking to stop the allergic reaction.
Many allergy medications on the shelves of your local drugstore work as antihistamines. But there are also certain foods and plant extracts that may similarly block the effects of histamine.”
“DAO acts on histamine both inside and outside the body. Within the body, DAO is found principally in the kidneys, thymus, and the placenta in pregnant women. When histamine levels inside the body become excessive, DAO, and another enzyme called histamine N-methyl transferase (HNMT) break down the excess. Excess histamine can rise inside the body (called endogenous histamine) as it is released from mast cells in a number of conditions including allergy, mast cell activation disorders, chronic inflammation, infection, and trauma, among others.
The digestive canal is essentially an area outside the body as materials enter at one end and exit at the other. Only the digested products enter the body through the epithelium and pass into circulation. DAO is found in the ileum and jejunum of the small intestine. It mixes with food, beverages and other ingested materials as they pass through the digestive tract. As the DAO encounters histamine in these substances, it breaks it down, thus preventing this external source of histamine (called exogenous histamine) from entering the body. When DAO is adequate and functioning efficiently, almost 99% of exogenous histamine is broken down within the digestive tract lumen and removed before it can enter the body. It is estimated that only about 1% of histamine from this source actually enters circulation. When DAO is deficient, far more histamine enters and builds up within the body.”
“Our body is a machine for living. It is organised for that, it is its nature. Let life go on in it unhindered and let it defend itself, it will do more for you than if you paralyse it by encumbering it with rememdies.” – Leo Tolstoy.
“Says Dr Janice Joneja:
“I have a number of patients who cannot take these (DAO) supplements because they are allergic to pork, or cannot consume them for religious or cultural reasons. The commercial sources of DAO are derived from pig kidney and those allergic to pork tend to develop quite severe allergic reactions to the products.
In my research, I have identified a plant source of DAO: pea seedlings.”
