Imagine sitting down to an ordinary meal: a piece of aged cheese, pickled fish, food with hot spices, or even a plate of fava beans. After a few minutes, your face begins to redden, you feel heat rising to your head, perhaps a throbbing headache, or nasal congestion, or heart palpitations, or skin itching. You wonder: what happened? Why is my body treating this meal as if it were a danger? In the Tayyibat System, Dr. Diaa Al-Awadi, may Allah have mercy on him, provides a clear explanation for this common phenomenon: some foods may stimulate the release of histamine in the body, or contain ready-made histamine, causing blood vessel dilation, redness, congestion, and allergy-like symptoms, but not always allergy in the traditional sense. This “boiling” is a rapid inflammatory response, varying in intensity from person to person depending on the body’s sensitivity and the state of the digestive and immune systems.

Why Do People Respond Differently to Food?
Two people may sit at the same table, eat the same food, and one experiences redness, palpitations, and headache while the other feels nothing. This difference is not random. Dr. Diaa Al-Awadi, may Allah have mercy on him, explains that the body’s response to food depends on multiple factors. First: the state of the digestive system (whether it is healthy or inflamed). A bloated colon or leaky gut allows larger particles to pass into the blood, increasing the chance of a response. Second: the efficiency of the liver in breaking down histamine and other substances. Some people have low activity of histamine-degrading enzymes (such as DAO). Third: the sensitivity of the immune system and background inflammation. If the body is already in a state of chronic inflammation, any addition may cause faster “ignition.” Fourth: the type of food itself and how it is prepared. Differences in response are not a judgment that a food is “harmful to everyone,” but rather a variation in individual susceptibility.
What Does Dr. Diaa Mean by the Body “Boiling”?
The expression “boiling” is not just folk speech; it is an accurate description of what happens inside blood vessels. Dr. Diaa Al-Awadi, may Allah have mercy on him, explains that some foods stimulate the release of histamine, or contain it ready-made. Histamine dilates small blood vessels (capillaries) and increases their permeability. The result: more blood flows to the face, neck, and chest, causing redness and a feeling of heat. This process may be accompanied by other symptoms: rapid heartbeat (because dilated vessels require higher pressure to circulate blood), headache (due to blood vessel dilation in the brain), nasal congestion (dilation of nasal mucosal vessels), and itching or rash. This “boiling” is a rapid vascular inflammatory response, different from classic allergy (which involves IgE antibodies) and may be called “histamine intolerance” or “allergy-like reaction.”
What Is Histamine in Simple Terms?
Histamine is a chemical substance produced by body cells (especially mast cells and basophils) and also found in some foods. In the body, histamine has multiple functions: regulating stomach acid secretion, dilating blood vessels, and playing a key role in allergic responses (against true allergens). The problem occurs when there is an excess of histamine, or when the body is less able to break it down, or when foods rich in histamine or that stimulate its release are ingested. Foods rich in histamine include: aged and ripened cheese, pickled and canned fish, processed meats (sausage, salami), pickles, and some yeasts and fermented drinks (wine, beer, some fermented beverages). Some foods do not contain histamine but stimulate cells to release it (such as eggs, strawberries, and citrus fruits). Histamine itself is not “harmful” in an absolute sense, but elevated blood levels or hypersensitivity to it cause unpleasant symptoms.
Why Do Some Foods Cause a Rapid Response?
Some foods lead to symptoms within minutes of consumption. There are multiple reasons. First: they contain ready-made histamine that is rapidly absorbed from the intestine (especially if the intestine is inflamed or leaky). Second: they stimulate the release of histamine from body cells directly (such as egg whites, strawberries, chocolate, some nuts). Third: they inhibit histamine breakdown, prolonging its effect. Some foods contain substances that inhibit the DAO enzyme responsible for histamine breakdown (such as alcohol). Fourth: they cause a comprehensive inflammatory response through other mechanisms (such as refined sugars and hydrogenated oils). Individual variation here is very large: one person may react strongly to a small piece of cheese, while another eats the same amount without symptoms. The difference lies in the efficiency of breakdown mechanisms, the integrity of the intestinal wall, and the sensitivity of histamine receptor cells.
How Do Symptoms Appear Inside the Body?
Symptoms depend on which tissues are affected by histamine. Vascular system: vasodilation causes redness, feeling of heat, and possible drop in blood pressure (and may cause palpitations as compensation). Respiratory system: nasal congestion, runny nose, sneezing, and may lead to shortness of breath in severe sensitivity. Digestive system: nausea, cramps, diarrhea. Skin: itching, hives (raised red rash). Nervous system: headache, dizziness, and may lead to anxiety or insomnia in some people. These symptoms may come together or individually, and their severity may vary from one time to another depending on what you ate, the amount of accumulated histamine, and the state of your digestive system. These symptoms are not “imagination” and are not always “true allergy” requiring epinephrine injections, but they are annoying and can disrupt daily life.
What Is the Relationship Between Inflammation and the Immune System?
Histamine is one of the inflammatory mediators. When secreted in the context of chronic low-grade inflammation, it may cause mild, recurrent symptoms without reaching anaphylactic shock. A body already suffering from chronic inflammation (due to poor nutrition, irritated colon, chronic stress, lack of sleep) has a high “inflammatory background,” making it more sensitive to any additional trigger (histamine-containing foods, foods that ferment in the colon, hot spices). The immune system in this state is in constant alarm, amplifying its response to triggers that might pass without symptoms in another person. This is why improving gut health and reducing general inflammation (by removing stimulating foods) may significantly reduce the symptoms of “boiling” in response to certain foods, even if the person still consumes them occasionally.
Why Do Not Everyone React in the Same Way?
Individual variation in response to histamine and histamine-triggering foods is due to multiple reasons. First: genetic differences in histamine-degrading enzymes (DAO and HNMT). Some people produce smaller amounts of these enzymes or less efficient enzymes. Second: the health and permeability of the intestinal wall. If the gut is “leaky,” histamine and large particles pass into the blood more easily. Third: the state of chronic inflammation in the body. Fourth: taking medications that inhibit histamine breakdown (some antidepressants, blood pressure medications, painkillers). Fifth: presence of coexisting diseases (true allergies, obesity, hormonal disorders). This variation explains why one person may need to avoid certain foods while another consumes them freely. A healthy system is not a one-size-fits-all template. Listening to your body and cautiously experimenting with food is key.
How Does This Understanding Change Our View of Food and Symptoms?
The biggest change is moving from thinking “this food is absolutely harmful or healthy” to thinking “how does my body respond to this food?” The question is no longer “is cheese harmful?” but “does this cheese cause me symptoms? and what amount triggers symptoms?” This understanding frees a person from following a harsh diet based on general fear and encourages self-observation and conscious experimentation. It also clarifies that symptoms such as facial redness or post-meal headaches are not “imagination”; they are real physiological responses that may be caused by histamine, inflammation, or individual sensitivity. This understanding directs the person toward addressing the causes: improving gut health, reducing general inflammation, and perhaps temporarily avoiding some high-histamine foods until the body calms down, rather than permanent deprivation and chronic anxiety.
Conclusion
Histamine and inflammation are the keys to understanding the phenomenon of the body “boiling” after certain foods. Some foods contain ready-made histamine, or stimulate its release in the body, or inhibit its breakdown. Histamine dilates blood vessels and increases their permeability, causing redness, heat, headache, congestion, palpitations, and other symptoms. Individual variation in response is due to genetic factors, gut health, and breakdown efficiency. These symptoms are not always “allergy” in the traditional sense, but they are real and annoying. Understanding histamine changes how we view food: do not only ask “is this food generally healthy?” but “how does my body specifically respond to it?” Improving gut health (by removing inflammation-causing foods: white flour, dairy, eggs, legumes) may reduce symptom severity. This understanding gives the person tools to deal with their symptoms, rather than living in confusion and fear of food.

It describes a rapid vascular response: redness, heat, palpitations, headache, congestion. It occurs due to blood vessel dilation and increased permeability from histamine release.
Aged and ripened cheese, pickled and canned fish, processed meats (sausage, salami), pickles, some yeasts and fermented drinks, and sometimes eggs, strawberries, and citrus fruits.
Not necessarily. Classic food allergy involves the immune system and IgE antibodies. This may be “histamine intolerance” or an allergy-like reaction, less severe but still annoying.
A chemical substance produced by body cells and found in some foods. It causes blood vessel dilation and increased permeability, playing roles in stomach acid regulation and allergic responses.
Due to genetic differences in histamine-degrading enzymes, intestinal wall health and permeability, chronic inflammation state, and medications that may inhibit breakdown.
By temporarily avoiding high-histamine foods, improving gut health (by removing inflammation-causing foods: white flour, dairy, eggs, legumes), supporting liver function, and reducing general inflammation and stress.
No, histamine is part of normal body functions (stomach regulation, immune response). The problem occurs when there is excess, poor breakdown, or hypersensitivity.
If symptoms are severe (difficulty breathing, facial or throat swelling, sharp blood pressure drop), it may be a true, dangerous allergy. Mild to moderate recurrent symptoms should be discussed with your doctor to understand the cause.
