Histamine intolerance: causes and treatment. Histamine intolerance is a fairy common but under recognised and not fully understood problem linked with food sensitivities as well as gut and metabolic imbalances. When a person has problems metabolising and breaking down histamine, its levels build up and lead to worrying symptoms such as hives, rashes and itching, among others (see more symptoms below). This disorder could be difficult to diagnose as it’s often confused with a number of other conditions that have similar symptoms, especially associated with food allergies. In my practice I see this condition periodically especially in clients with gut disorders, skin problems, headaches or migraines. Let’s look at histamine intolerance more closely. About histamine. Histamine is an amine (an organic nitrogen compound) produced by the immune system cells (mast cells, basophils and eosinophils) involved in the inflammatory immune response to an injury or foreign compounds. The normal inflammatory response is a healing mechanism that increases the permeability of capillaries (small blood vessels) to white blood cells so they can combat the pathogens or toxins present. Histamine is also a neurotransmitter in the central nervous system (i. So we very much need histamine for the body to function well on many levels. The highest concentrations of histamine in the body are found in the tissues most exposed to the outside world such as the skin, mouth, sinuses, digestive tract and the lungs.

The Hydrochloric Acid Supplement is one of the most common and effective methods. Coconut oil for acne was at the top of my list of posts to write about getting clear skin. Here’s why: While I don’t agree with outright food worship, I have to. When I first heard of the test I was anxious to try it. I had struggled so much with illness and infection. It was very frustrating because I had made so many diet. We’re continuing with a series on people who have reported something going wrong when they tested some variation of the Perfect Health Diet. Histamine is also released in the body as part of an allergic reaction, causing the typical . Enzyme diamine oxidase (DAO) breaks down histamine and maintains a histamine balance in the body. However, some people have a low level of this enzyme, and when they eat too many histamine- rich foods, they may suffer . Microbial fermentation in the food converts the amino acid histidine present in high- protein foods to histamine. As such, histamine content of food increases over time as the food ages. Histidine is also produced by some of the species of bacteria found in the gut. If they proliferate too much due to the gut flora imbalances (also known as gut dysbiosis or SIBO – small intestine bacterial overgrowth) they produce too much histamine and the symptoms appear. This is one of the reasons why histamine intolerance is on the rise as an effect of alterations to our microbiota (gut flora) over the past 2. Causes of histamine intolerance. Overall, there are two main reasons for the symptoms to manifest: 1. Overproduction of histamine caused by: Gut dysbiosis/ SIBO – certain types of bacteria in the gut produce histamine and other types of bacteria degrade it maintaining balance. However, if there more than required of the histamine producing bacteria, histamine excess will occur. Histamine- producing bacteria include: Lactobacillus casei, Lactobacillus delbrueckii, Lactobacillus bulgaricus, Lactobacillus reuteri, and Lactococcus lactis, Enterococcus faecalis, and various types of E. Research on probiotics continues so our knowledge is expending but it’s incomplete for now. Read more on this here. Over activation of mast cells, which are the cells that largely produce histamine. We don’t fully understand what causes this at present. Inability to break histamine down properly caused by: Impaired methylation – histamine N- methyltransferase enzyme (involved in histamine breakdown) requires methylation to function properly for it to work efficiently. Therefore compromised methylation will cause a decrease in the breakdown of histamine. Not enough histamine- degrading bacteria – which is related to gut dysbiosis (as stated above). Genetics – genetic defects involving two enzymes: diamine oxidase (DAO) or histamine N- methyltransferase which bind and breakdown histamine preventing excess. Some people don’t make enough of these enzymes because of faulty genes. Also, some medications can facilitate histamine release, others can reduce the effectiveness of the DAO enzyme. As a result, the level of histamine rises and may cause symptoms, even in a person who has shown no signs of histamine intolerance in the past. Common pain killers such as aspirin, non- steroidal anti- inflammatory drugs (NSAIDs), some diuretics, antibiotics and antidepressants are among the medications that can affect the functioning of DAO (2). Moreover people with adrenal fatigue who have cortisol production imbalances such as high cortisol, low cortisol or faulty production of cortisol throughout the day, are more likely to produce excess histamine due to increased inflammation which triggers the release of histamine as a defence mechanism. Therefore dealing with adrenal fatigue is an important treatment step as well. Symptoms of histamine intolerance include: Hives (urticaria)Itching (pruritis) – especially of the skin, eyes, ears, and nose. Tissue swelling (angioedema) especially of facial and oral tissues and sometimes the throat, the latter causing the feeling of “throat tightening”Low blood pressure and fainting. Getting dizzy when standing up quickly. Rapid heartbeat / heart racing or tachycardia. Symptoms resembling anxiety or panic attack. Chest pain. Nasal congestion, runny nose, seasonal allergies. Conjunctivitis – irritated, watery, reddened eyes. Headaches and migraines. Fatigue, irritability, insomnia. Flushing and rosacea. Blacking out / loss of consciousness for a few seconds unexplained by other causes. Digestive tract issues especially heartburn, indigestion as well as constipation and diarrhoea. Please note that not all of the above symptoms occur in any single individual and the severity of symptoms varies, but the pattern seems to be consistent for each person. Importantly, if someone has multiple allergic responses that are not associated with any particular trigger food(s) or allergy test results are negative, it could be an issue with histamine intolerance. Foods high in histamine (an overview)PROTEINSDairy products – milk and most cultured dairy such as cheeses, kefir, yoghurt, sour cream, buttermilk, cottage cheese, ricotta. Leftover meat – after meat is cooked, the histamine levels increase due to microbial action as the meat is stored even in the fridge. Fish – unless very fresh, the longer it waits for consumption the more histamine it has; canned tuna and canned other fish Shellfish – particularly smoked or canned seafood and tuna Processed, cured, smoked and fermented meats – bacon, sausages, salami, pepperoni. Long cooked bone broth – chicken soup cooked for a few hours may be OK Nuts – especially peanuts, also walnuts and cashews. Eggs – especially egg whites. Beans and legumes (plant proteins) – chickpeas, soy beans, peanuts. VEGETABLES All tomato products – red tomatoes are higher histamine than yellow/orange Olives in vinegar or brine FRUITSDried fruits – prunes, cranberries, dates, figs, raisins, currants Citrus fruits – lemons, limes, oranges, grapefruits (increase histamine release) Most berries – including strawberries and raspberries DRINKSTea – black, green, & mate (stimulate histamine production) Alcohol of all types – especially wine and beer. Coffee beans (that are fermented)Cola and energy drinks SPICESCinnamon, cloves, chili powder, anise. Nutmeg, curry powder, cayenne, cloves, anise. Vinegar products – all vinegars including apple cider vinegar, pickles, ketchup, mustard FERMENTED FOODSSauerkraut, pickles, kombucha Yeast containing foods e. Check labels or talk to your doctor. Especially benzoates and sulphites also nitrates, glutamate (MSG), tartrazine. All products containing cocoa and raw cacao including chocolate of any kind. Please note the above list of foods is incomplete and other foods may also cause / contribute to the symptoms. This needs to be assessed on an individual basis. You can find a more comprehensive list of foods high and/or low in histamine here. Another excellent paper on histamine intolerance was published in August 2. Research Centers of Nutrition and Health (Grupo CINUSA) in Spain. The researchers conducted selective literature search for relevant publications in Pub. Med and other scientific data bases, combined with further data from the World Wide Web on histamine and other amines content in foods. The paper includes comprehensive cross- checked tables of foods that are low, moderate and high in histamine. The researchers concluded that further studies are necessary to establish safety limits for bioactive amines in food, and the intolerance they may cause. A must read for all who have histamine intolerance symptoms. Natural medicinetreatment options. Healing the gut is the top priority – most people with histamine intolerance have damaged guts resulting in a lack of capacity to produce the enzymes that metabolise histamine. In addition, an overgrowth of certain types of bacteria that make histamine from undigested food, leads to a build- up of histamine in the gut overwhelming the body’s ability to break down the excess histamine. This causes a heightened sensitivity to histamine- containing foods and an increase in symptoms that are commonly associated with allergies. Thus in most cases the underlying cause of histamine intolerance is likely due to existing gut dysbiosis. Therefore rebalancing the microflora to heal the leaky gut and/or SIBO is the key first step (3). Addressing methylation problems with testing, supplementation and diet. Low histamine diet – a very important part of the treatment. Adhering to a low- histamine diet for a period of time (or forever for some people) brings fast symptom relief in majority of cases. Sometimes when we start the treatment some particularly sensitive people are not able to tolerate any animal products and need to follow a plant- based diet to heal the gut and decrease the sensitivity. Fortunately, overtime these individuals will most likely be able to include some animal products in the diet.
