FAQs

Introduction To Immunohealth

I thought this kind of testing was only for allergists or specialized doctors. I’m not seeing an allergist—can I still use ImmunoHealth? Who will explain my results?

Absolutely—you do not need to be under the care of an allergist or endocrinologist to benefit from the ImmunoHealth program. When you purchase the test and enroll in the program, you are automatically paired with a certified ImmunoHealth consultant. Each consultant is trained and approved by ImmunoHealth and has the relevant clinical or nutritional background to interpret your results and guide you through the process with accuracy and care.
Your consultant is equipped to explain how your immune system is responding to specific foods—not just based on allergy, but based on delayed-type hypersensitivity, a distinct immunological pathway that’s often overlooked in conventional medicine. This type of reaction, involving immune complexes (antibody + antigen + complement protein), may contribute to a wide range of chronic symptoms—including skin issues, joint discomfort, digestive disturbances, and fatigue—without obvious links to digestion or classical food allergies.
These immune reactions can also contribute to broader systemic inflammation, which plays a role in issues like fluid retention, impaired metabolism, enzyme deficiencies, intestinal barrier dysfunction, dysbiosis, and even weight gain.
Your consultant’s role is not just to walk you through a report—it’s to help translate complex immune findings into clear, practical dietary guidance that aligns with your unique immune profile and health goals. You are not expected to interpret the science alone, though we strive to make it approachable.

Is it really necessary to do a consultation and opt for the program? The reports seem clear—can’t clients interpret them on their own?

While the ImmunoHealth software does automatically generate comprehensive and visually accessible result tables, a consultation is strongly recommended.
During a consultation, the trained consultant is able to:
Make informed adjustments based on the client’s symptom profile, medical history, lifestyle, dietary habits, and the consultant’s own expertise in immuno-nutrition;
Assess the client’s psychological readiness to modify eating behaviors and culinary habits;
Provide the motivational support necessary to foster compliance and long-term adherence;
Address any questions, reduce confusion, and ensure the client begins the program with clarity and confidence.
Decades of clinical practice abroad and client engagement have shown that the success of the ImmunoHealth approach significantly improves when clients are guided by a trained professional. Ongoing support allows clients to track their progress, share insights or concerns, and collaboratively celebrate milestones. This sustained relationship not only empowers the client but also enhances the efficacy and sustainability of the intervention.

How does the ImmunoHealth test differ from a standard allergy test? What is the difference between hypersensitivity and allergy?

It's easier to start by explaining what these tests have in common. Both tests utilize a laboratory method called enzyme-linked immunosorbent assay (ELISA) to detect specific immunoglobulins (antibodies) in the blood. However, they detect entirely different classes of antibodies, representing fundamentally different immune response types.
Traditional allergies are known as immediate-type hypersensitivity reactions. These reactions involve Immunoglobulin E (IgE) antibodies and lead to rapid, noticeable clinical symptoms such as hives, swelling, and even anaphylaxis. Thus, what we commonly refer to as "allergies" typically corresponds to these immediate-type reactions.
Conversely, the ImmunoHealth test focuses on delayed humoral hypersensitivity, involving Immunoglobulin G (IgG). This type of reaction does not cause immediate symptoms but instead manifests as chronic, systemic inflammation in various body tissues, often masquerading as long-term chronic conditions. These reactions occur due to immune complexes formed by circulating IgG antibodies binding to specific food antigens, triggering inflammation.
Therefore, while traditional allergy tests detect rapid allergic reactions, ImmunoHealth identifies slower, hidden reactions linked to chronic health issues, providing a more comprehensive and tailored dietary guidance.

How does ImmunoHealth differ from the IgG ELISA tests available at laboratories and other companies?

ImmunoHealth fundamentally differs in its analytical method and interpretation. The key distinction lies in the personalized determination of the threshold between normal and abnormal immune reactions, considering each client’s immune system activity levels. Our method was patented in the USA in 2007, and the proprietary software used to determine this individual threshold and generate detailed test result tables has been certified as a medical device abroad (RU № RZN 2020/9970). A novel patent is expected to be filed by the end of 2025 along with concurrent patents in other locales.

What antigens does the ImmunoHealth test identify, and how does it differ from similar tests?

The ImmunoHealth test does not identify the antigens themselves directly. Instead, it measures quantitative characteristics of humoral immunity related to the production and circulation of specific antibodies to each tested food antigen. The level of immune reaction is determined by the concentration of these specific antibodies accumulated in the blood. Detailed antigen compositions for our test panels are available on our website.
Our offerings include:
A Standard dietary panel consisting of 90 antigens, favored by nutritionists and medical professionals from various specialties (Standard Test).
A Premium panel of 180 antigens, including delicacies and more exotic foods.

Comparisons To Other Diets & Tests

How does ImmunoHealth differ from the Autoimmune Protocol (AIP)?

ImmunoHealth is a personalized nutritional approach that refines and tailors the general principles of AIP to suit your unique body's needs. Unlike the AIP, which applies broad dietary restrictions universally, the ImmunoHealth method precisely identifies the specific foods triggering an immune reaction in your body. There's no need to exclude foods that are safe for you—we only target those genuinely causing harm. Additionally, ImmunoHealth is dynamic; as your body heals, restrictions are gradually relaxed, transitioning into a comfortable, sustainable dietary lifestyle.

Can the Paleo diet be considered equivalent to the ImmunoHealth diet based on test results?

No, these approaches are fundamentally different. The Paleo diet is a standardized nutritional system based on statistically common allergens and inflammation-triggering foods. This general approach often provides rapid symptom relief, contributing to its popularity. However, maintaining such strict, generalized dietary restrictions over the long term can be challenging, and the Paleo diet isn't designed for permanent adherence. In contrast, ImmunoHealth doesn’t rely on averaged statistics. Instead, it identifies foods that specifically trigger reactions in your body, making the approach not only more effective but also more manageable and sustainable long-term, supporting your journey toward a healthier lifestyle rather than offering merely a short-term solution.

If certain inflammatory foods like dairy proteins, gluten, and yeast are commonly problematic, wouldn’t it be easier to just eliminate them from the diet without doing an expensive test?

That approach does exist—most notably in the Autoimmune Protocol (AIP) diet. It often yields a relatively high percentage of positive outcomes, especially in individuals with clear inflammatory or autoimmune conditions.
However, this method doesn’t work universally. Each client presents with a unique immune profile, and individual sensitivities can vary widely. Inflammation may be driven by subtle and highly personal factors that general protocols do not address. Ignoring those nuances can limit both the effectiveness and sustainability of the dietary intervention.
That’s why ImmunoHealth’s culinary resources and recipe guides are designed around the most commonly problematic ingredients—while still emphasizing personalization. Of course, individuals may choose to begin their journey without testing, experimenting through elimination on their own. But for those seeking precision, efficiency, and long-term results tailored to their immune system, the ImmunoHealth test offers a powerful and evidence-based advantage.

If I eat the same foods all the time, won’t they inevitably end up in the “red” zone? And if I stop eating them, won’t they shift to the “green” zone? In that case, why not just use a basic elimination-rotation diet instead of testing?

That’s a valid observation—particularly in relatively healthy individuals. Seasonal overload or excessive consumption of certain foods can lead to transient increases in intestinal permeability, and mild immune deviations may occur as a result. However, these typically present as minor fluctuations within the individual’s normal range of immune response distribution and are not sufficient to explain deeper systemic issues.
Some foods may appear in the “red” zone due to seasonal overexposure, but this is fundamentally different from the immune reactivity seen in cases of chronic inflammation or immune dysregulation.
The ImmunoHealth test is specifically designed for individuals experiencing persistent, unexplained symptoms or pathological conditions. In such cases, the standard elimination-rotation diet may fall short without precise identification of immunological triggers. The test offers clarity where guesswork may lead to unnecessary restrictions or missed culprits—making it an essential tool when clinical accuracy is required.

Is there a reason to conduct an ImmunoHealth test if I already have genetic testing results?

A genetic test reflects your genotype, which is your unique combination of genes. Each gene is associated with the synthesis of specific proteins and can indicate risks of functional disruptions or variations if genetic polymorphisms (inherited changes) are present. Genes relevant to nutrition typically include those responsible for enzymes, hormones, neuropeptides, cytokines, and receptors related to insulin, serotonin, cholesterol, vitamins, and more. Genetic information helps explain why certain foods might remain problematic even after an elimination diet. Importantly, genetics reveal risks for developing various diseases, including gastrointestinal issues and immune system reactivity, such as allergies or autoimmune conditions. However, many genetically inherited risks may never materialize, depending instead on epigenetic factors—nutrition being one of the most critical.
In contrast, the ImmunoHealth test reveals phenotypic characteristics—the actual, real-time state of your body, reflecting recent dietary patterns (approximately the past three months). While genetic testing offers strategic insights and risk assessments for potential future health issues, the ImmunoHealth test provides tactical, actionable guidance based on your current state of immune system and homeostasis.
Therefore, genetic testing and ImmunoHealth testing complement each other, together offering a comprehensive view to help develop both immediate dietary interventions and long-term personalized health strategies.

What if my ImmunoHealth results don’t match my genetic test?

When both tests are interpreted by a qualified professional, such a discrepancy should not be seen as a contradiction. Rather, it reflects the different nature and timing of what these tests measure. Genetic testing analyzes your inherited traits—your genotype—and identifies risks linked to protein function, metabolism, immune activity, and disease predispositions. However, many of these risks may never manifest, as their activation depends on external factors like lifestyle and environment.
ImmunoHealth, on the other hand, assesses your phenotype—how your body is actually responding in the here and now, especially in terms of immune sensitivity to foods. These results are shaped by recent diet, lifestyle, medication use, and underlying health conditions. In other words, ImmunoHealth reveals how inherited predispositions are currently being expressed, if at all.
A mismatch between tests may occur, for example, if a client is genetically predisposed to an intolerance (like lactose) but has not consumed the trigger food recently, or if epigenetic influences such as inflammation or gut dysbiosis have overridden the expected genetic response. Food maladaptation—what the ImmunoHealth test captures—is a composite result of both genetic potential and real-time immune and digestive function. That’s why the two tests are not contradictory but deeply complementary: one offers a blueprint of risk, the other a snapshot of reality.
AM I STUCK WITH MY RESULTS FOREVER?

Who The Test Is For & When To Test

At what age can the ImmunoHealth test be performed?

The test can be conducted as soon as the child’s diet is sufficiently varied that it becomes difficult to identify trigger foods using a food diary alone. In theory, testing is generally recommended after the age of two, as this coincides with greater maturity of the immune system and its ability to produce measurable antibody responses.
However, in cases where a child presents with pronounced clinical symptoms and IgE-mediated (immediate-type) allergies to food antigens have been ruled out, testing may be considered as early as 12 months of age. Clinical judgment is essential, and the decision should be made in consultation with a qualified healthcare provider.

I’m pregnant. Can I take the test?

Yes—and in fact, it’s recommended. Testing during pregnancy can help reduce the antigenic burden on the mother’s immune system, which benefits both the mother and the developing child. IgG antibodies freely cross the placenta and are also transferred through breast milk via the gastrointestinal tract, influencing the infant’s early immune environment.
That said, certain precautions apply. During pregnancy, the anti-Candida protocol is not prescribed, and special attention is given to ensuring the nutritional adequacy of the elimination diet. Any dietary adjustments must be carefully supervised to support both maternal health and fetal development.

I take hormones regularly. Will the test still be accurate?

It depends on the type of hormone. If you are taking thyroid hormones, the test will remain fully accurate and reliable.
However, oral corticosteroids suppress immune system activity and can significantly alter test results. Their use is considered a relative contraindication for the ImmunoHealth test. Ideally, testing should be postponed for two months after discontinuing corticosteroids. If that’s not possible, your physician should be made aware and should order additional laboratory assessments—including total protein, inflammatory markers, and serum immunoglobulins (IgG, IgM, IgA)—to interpret the data correctly. Without these adjustments, the test results may not be suitable for building a valid nutritional protocol.As an exception, the test may be performed in clients on low-dose corticosteroids (≤10 mg/day). In such cases, we proceed with caution and interpret the results knowing that immune reactivity may appear blunted due to medication effects. Kindly advise your consultant if this applies to you.

I haven’t eaten meat or bread in several years. Will the test results for these foods still be accurate?

For meat, the test may show negative or very low IgG reactivity, but this could be a false-negative result due to prolonged absence of exposure. Without contact with the antigen, the corresponding antibodies gradually break down and are cleared from the bloodstream—typically within six months. If there is no re-exposure, no new antibodies are produced, and immune memory fades from the test’s perspective.
Bread, on the other hand, contains multiple ingredients—most notably wheat. If you have excluded only bread but still consume wheat in other forms (such as pasta, pastries, or sauces with thickeners), the test will still be valid for assessing wheat-related immune responses. Accuracy depends on whether the full source antigen (e.g., wheat, not just bread) has been eliminated.

I’ve tried many treatments, but my symptoms keep coming back. Could hidden food sensitivities be the reason?

Yes—many chronic conditions that are resistant to treatment or recur shortly after standard care may be linked to hidden, delayed immune responses to certain foods. These reactions often don’t show up on traditional allergy tests, but they can contribute to systemic inflammation and immune imbalance over time.
Conditions commonly associated with food hypersensitivities include:

  • Irritable bowel syndrome (IBS), ulcerative colitis, or other digestive issues
  • Persistent weight gain or difficulty losing weight
  • Type 2 diabetes or insulin resistance
  • Chronic fatigue or low energy
  • Hormonal imbalances (thyroid, adrenal, reproductive)
  • Skin conditions such as eczema, acne, or psoriasis
  • Joint pain, arthritis, fibromyalgia, or unexplained muscle aches
  • Migraines and frequent headaches
  • Anxiety, low mood, or depression

ImmunoHealth testing helps uncover these hidden immune reactions. By tailoring your diet based on real immune data—and supporting gut microbiota and enzyme function—many clients experience significant symptom relief, and in some cases, full resolution of chronic complaints. If conventional approaches haven’t provided lasting results, this may be the missing piece.

Science & Technical Foundations

How can a “dried blood spot” provide reliable information?

In the same way that dried protein structures are used in fields such as genetics, forensic science, and paleontology. Unlike cellular tests, immunological assays focus on protein-based structures—specifically immunoglobulins (antibodies). These antibodies bind selectively to food antigens immobilized on the test panel surface, enabling detection through antigen-antibody interactions.
Drying is simply a preservation technique that maintains the biological material in a stable form. Proteins, like gelatin, crystallize in a dried state but can regain their native conformation when reconstituted in a salt solution that mimics the concentration of human serum. This advanced preservation method retains the analytical integrity of the sample: dried blood spots can remain viable at room temperature for months, and for years when refrigerated.
While the underlying technology is complex, it is well-established in medical practice. For example, the same type of collection cards (e.g., Whatman cards) and micro-lancets are routinely used in neonatal screening to detect congenital metabolic disorders—where blood is collected from a newborn’s heel.

How is it possible to measure immune responses to 90 or even 180 different foods using just a few drops of dried blood?

The method relies on five properly collected and dried blood spots, each containing approximately 30–50 µL of blood, deposited onto a specialized absorbent filtration material. This technique—known as the Dried Blood Spot (DBS) method—was developed by American scientists and has long been used in immunological testing. For example, it forms the basis of mandatory neonatal screening for congenital enzyme disorders in the US and many other countries.
From the dried blood spots, serum is extracted using a physiologic solution from the reverse side of the collection card. This eluate is then homogenized and dispensed via multichannel pipette into a transparent test panel containing immobilized food antigens in separate wells. After a period of incubation, the panel is washed to remove unbound antibodies. The bound antibodies are then quantified using spectrophotometry, which measures changes in optical density in each well. This yields precise digital data on the concentration of specific IgG antibodies that reacted to each food antigen—allowing for comprehensive profiling from a minimal blood volume.

Do I need to prepare before blood collection—such as fasting or pausing food intake?

No special preparation is required prior to blood collection. The test can be performed at any time of day, regardless of recent food intake. This is because the analysis targets IgG immunoglobulins, which circulate in the bloodstream for extended periods and are unaffected by short-term dietary intake.

How quickly must the sample card be sent to the laboratory to ensure accurate results?

Blood collection for the ImmunoHealth test is performed using specialized Whatman absorbent cards. Research confirms that, when properly dried, these cards preserve sample integrity for up to 30 days at room temperature. This window allows for safe and effective transportation over long distances without compromising analytical accuracy.
With our convenient and fast prepaid return envelope, we are confident that you will be able to meet the recommended delivery timeframe with ease.

Are there any rules I should follow before taking the test? Can I eat, drink, or take medications beforehand?

No special preparation is required before collecting the blood sample. The test can be performed at any time of day, regardless of food or fluid intake, since it measures IgG antibodies that circulate in the bloodstream over extended periods.
As for medications, it depends on the type:
Antihistamines do not affect the test results, as they do not interfere with Type III hypersensitivity reactions—the mechanism assessed in this test.
Systemic corticosteroids, however, may suppress immune activity and can compromise the accuracy of the results. If a client is taking oral steroids, the test should ideally be postponed for at least two months following discontinuation. Alternatively, if your prescribing physician takes this into account and orders additional lab tests (such as total protein, inflammatory markers, and serum immunoglobulins including IgG, IgM, and IgA) interpret the results may be interpreted correctly. Without this context, the data may be unsuitable for developing a personalized nutritional protocol.
Importantly, acute episodes of Type I allergy (immediate hypersensitivity) are not a contraindication for testing. On the contrary, during such periods it is especially beneficial to reduce the immune system’s burden by identifying and removing contributing food antigens.

I’ve read in respected physiology and nutrition textbooks that food is broken down into its most basic molecular components in the GI tract, making it unrecognizable to the immune system. But your test examines immune responses to food antigens—how is that possible?

Unfortunately, many of those textbooks reflect scientific understanding from 30 or more years ago. Today, the mechanisms by which macromolecules, microparticles, and even entire microorganisms can enter the bloodstream through an intact intestinal barrier are well-documented. Two such mechanisms include bacterial translocation and transcytosis. Examples of this phenomenon are numerous and clinically accepted: oral administration of high-molecular-weight pharmaceuticals (such as thyroid hormones), maternal antibodies and hormones transmitted via breast milk, and protein-based immunotherapies all demonstrate that complex molecules can indeed pass through the gut barrier and retain biological activity.
Moreover, inflammation in the intestinal wall—often triggered by imbalances in gut microbiota—can lead to a condition commonly referred to as “leaky gut syndrome.” In this state, the permeability of the intestinal lining is compromised, allowing food-derived antigens to cross into the bloodstream where they may provoke an immune response.
Thus, the presence of food antigens in circulation is not only plausible—it is a well-established aspect of modern immunological science.

Understanding Results & Immune Responses

Why did the ImmunoHealth test not detect my confirmed allergic reaction to cod?

Your confirmed allergy to cod was likely identified through an IgE test, which detects immediate-type allergic reactions. ImmunoHealth measures IgG antibodies, which are involved in delayed-type hypersensitivity reactions. IgE and IgG responses rarely coincide, particularly when the allergenic food, in this case cod, has been fully excluded from your diet for an extended period. After about three months of eliminating an allergenic food, IgG antibodies typically diminish and may not be detectable, leading to a potentially false-negative result in IgG-based testing.

A product showed up in the “red” list, but I don’t feel any symptoms when I eat it. Does that mean I can keep eating it?

Not necessarily. The ImmunoHealth method is specifically designed to detect delayed hypersensitivity reactions—subtle immune responses that are often difficult to connect with specific foods. When such foods are eaten regularly, their effects may not be immediately noticeable. Symptoms may surface only 2 to 4 days after consumption, or present as chronic, persistent conditions with no clear pattern. In these cases, it becomes nearly impossible to identify the cause without testing.
What often happens is that clients begin to experience clarity only after removing the trigger foods. During the elimination phase, many report that longstanding symptoms begin to fade. This retrospective realization confirms the connection between immune activity and the food, even in the absence of obvious symptoms at the outset.

Why do some foods with relatively low IgG numbers (titers) appear in the red list?

This is a frequent question that arises when a client gains access to the technical component of their report, which is primarily intended for specialist interpretation. According to ImmunoHealth methodology, foods are not placed on the red list solely based on exceeding a fixed antibody threshold. Instead, red list classification incorporates a broader immunological context, where certain foods are recognized as markers of disrupted immune tolerance—even when their quantitative antibody levels are below the individual threshold of abnormality.
These foods are often implicated in immunological cross-reactivity due to shared molecular epitopes or phylogenetic relatedness with more reactive antigens. For instance, cross-reactive clusters such as wheat-rye-barley or nightshades (e.g., potato, eggplant, tomato, bell pepper) may contain structurally similar antigenic determinants capable of triggering or sustaining systemic inflammatory processes. Thus, even if individual titers are modest, their immunological relevance may be elevated due to this pattern-based analysis.Consequently, the exclusion rationale in ImmunoHealth extends beyond numerical IgG values, incorporating qualitative insights into antigenic clustering, cross-reactivity, and the broader immunopathophysiological role of implicated food groups. This allows for more accurate identification of dietary triggers and a more meaningful modulation of the client’s antigenic load.

How is the “yellow” list different from the “red” list, and how often can foods from the yellow list be consumed?

The “yellow” list represents a set of temporary dietary restrictions implemented during the initial phase of the program—specifically aimed at rebalancing the gut microbiota. Foods in this category should not be consumed during the first few weeks, particularly when following an anti-fermentation or anti-Candida protocol.
Typically, after approximately four weeks, the consultant may begin reintroducing yellow list items gradually, while monitoring the client’s response. The rationale for this temporary exclusion is to halt fermentative processes in the gut, reduce the biomass of fermentative or opportunistic microbes, and promote the growth of beneficial symbiotic bacteria.
Unlike “red” list foods, which reflect sustained immune intolerance and often require long-term exclusion, “yellow” list foods may be reintegrated on a case-by-case basis, depending on the client’s progress and immune response dynamics.

Can I eat green list foods freely, avoid red forever, and have yellow once a week?

Not quite. While green list foods—those showing a normal immune response—form the core of your diet and can be consumed regularly, we still recommend rotating them to avoid overexposure. Portion size should be guided by hunger, satiety, and healthy meal intervals.Red list foods should be strictly eliminated for a minimum of 3 months, especially if antibody levels are high. In many cases, only a repeat test can determine whether it's safe to reintroduce them. Some red list foods may never be tolerated and must be excluded long-term.
Yellow list foods are more nuanced. If high Candida or yeast-related antibodies are detected, a 4-week anti-yeast protocol is advised. During this period, even foods from the green list that contain bioavailable carbohydrates may be temporarily moved to yellow and eliminated. This adjustment can also apply even if Candida markers are not elevated, but symptoms or history suggest fungal overgrowth.
Following this protocol, reintroduction of yellow list foods should be gradual and supervised, one at a time. The program also flags products with known cross-reactivity for strict temporary exclusion.
Ultimately, the color coding is a useful tool, not a permanent label. Foods can move between categories depending on immune dynamics, symptom history, and test timing.

How is it possible to react to a food you’ve never eaten?

This is most commonly explained by cross-reactivity. For example, peanuts and all varieties of beans belong to the same botanical family. Individuals who are highly sensitive to peanuts—sometimes even to their smell—often exhibit an immune response to beans as well, even if they haven’t knowingly consumed peanuts.
Similar cross-reactive patterns are frequently observed among shellfish, mushrooms, citrus fruits, and members of the nightshade family (such as tomatoes, eggplants, and peppers). Another possibility is hidden exposure—many food antigens may be present in processed products or biologically active supplements (such as nutraceuticals), even if the client hasn’t consumed the food in its raw or whole form.
These immunological connections highlight the importance of a comprehensive and individualized interpretation of test results under professional supervision.

Will food reactions in parents and children be the same?

Similarities are common, but not guaranteed—and certainly never identical. While genetic predispositions can influence immune reactivity and digestive enzyme profiles, each individual's immune system develops uniquely in response to their own exposures, environment, and microbiota composition. Therefore, food sensitivities and intolerances may partially overlap within families, but every case requires personalized assessment and testing.

How can a child have a reaction to shellfish or avocado if they’ve never eaten them?

This is a classic example of cross-reactivity. The immune system may recognize and react to molecular structures in shellfish or avocado that are similar to those in other foods or environmental antigens the child has been exposed to. These structural similarities can trigger an immune response even without direct consumption of the food in question. Cross-reactive responses are well-documented in immunology and are particularly relevant in early-life immune development.

Our ancestors ate milk, bread, and tomatoes their entire lives. Why are we being told to avoid them now?

Of course these foods can be consumed—but the real question is: should everyone be consuming them? This is a nuanced issue rooted in the biological concept of adaptation to dietary environment.
Wheat entered the human diet approximately 10,000 years ago. Tomatoes arrived in Europe during the Columbian exchange about 500 years ago—relatively recently in evolutionary terms. While the tomato has remained largely unchanged at the molecular level, both milk and modern wheat products have undergone significant transformations in their antigenic (and thus allergenic) properties.
The principle is simple: “What no longer spoils, no longer digests properly.” In nature, fiber and most carbohydrates are meant to be processed by our gut microbiota—not just by the digestive enzymes we produce. But the diversity and composition of the human microbiome has dramatically deteriorated in the era of antibiotics, preservatives, and industrial food processing. We are not biologically equivalent to the ancestors you reference.
In fact, comparative studies of the gut microbiota between modern urban dwellers and traditional rural populations reveal major differences that do not favor the immune resilience of contemporary humans. We face a vastly different immunological landscape today—altered foods, compromised digestion, and impaired intestinal barrier function all contribute to the growing burden on our immune systems.
If in doubt, just take a look at the rising incidence of allergic and autoimmune diseases in developed nations. The data speaks for itself.

Why are dairy products often in the “red” list? Can I still have fermented dairy? Why are goat and sheep milk sometimes allowed, but cow’s milk is not? And what about children—can they have dairy?

Dairy products are frequently found in the “red” list because cow’s milk—being a foreign biological substance, especially for adults—is not easily tolerated by the immune system. While young children (typically under 2–3 years old) produce specialized enzymes to help digest milk, this capacity often declines with age. Moreover, each animal species produces milk with a unique set of proteins, which is why reactions to dairy from cows, goats, and sheep must be assessed separately.
Historically, the majority of the world’s population descends from nomadic herding cultures. Goat and sheep milk were far more accessible in such settings than cow’s milk, due to the practical limitations of moving large cattle. Consequently, many individuals have developed a higher tolerance to goat and sheep milk proteins, while still reacting to bovine milk.
Immunological reactions to dairy are primarily triggered by milk proteins—especially casein—not by lactose. Therefore, neither fermenting, boiling, nor switching to lactose-free milk resolves the underlying issue if the body produces antibodies against casein or other milk proteins. These proteins are structurally resilient and remain immunologically active despite processing.
This is particularly relevant for children. Many chronic pediatric conditions—eczema, recurrent upper respiratory infections, pseudocroup, asthma, obesity, and attention deficits—have been increasingly associated with undiagnosed sensitivity to milk proteins. Today, pediatricians are better equipped to identify these issues and recommend hypoallergenic, dairy-free formulas and milk substitutes.
In such cases, avoiding all forms of dairy—even fermented or lactose-free—may be necessary to reduce inflammatory immune responses and restore health.

Retesting & Long-term Strategy

When should I repeat the ImmunoHealth test after the initial results?

We recommend repeating the ImmunoHealth test no sooner than three months after the first one. IgG antibodies, which the test measures, have a biological half-life of approximately 1.5 to 3 months, depending on the initial level and immune system activity. While clinical symptoms may change quickly, blood antibody levels take longer to adjust. Around the 5- to 6-month mark, the value of repeating the test starts to diminish. However, after 3 to 4 months of consistent elimination, you may observe a near-total disappearance of antibodies not only related to seasonal or cross-reactive overloads but also to food antigens driving hypersensitivity. Timing your retest within this window ensures the most meaningful and accurate results.

Is the ImmunoHealth diet forever, or should the test be repeated periodically?

The ImmunoHealth test helps identify both persistent food intolerances and temporary seasonal overloads. In most cases, two tests spaced 3 to 4.5 months apart are sufficient to get a complete picture of your food immune responses. During that time, antibody levels related to frequent seasonal exposure typically decline, and cross-reactions resolve.
However, elevated levels to truly antagonistic foods—those that provoke abnormal immune responses—tend to drop slowly, often no more than a third after three months of full elimination.
This distinction helps determine which foods should be avoided entirely (with very rare reintroductions, no more than once every two months) and which can be rotated or rested seasonally. With accurate determination of your immune system’s reaction threshold, the vast majority of foods will remain on your "green list"—those to which your body shows tolerance and can be consumed in any season.
If over time your symptoms return or your overall well-being declines, you can always retest to identify what may now be disrupting your balance.

When can previously restricted foods be reintroduced?

Some foods should never be reintroduced, as the immune system is unlikely to ever build tolerance to them. For others—especially those that showed abnormally high IgG levels—they may be reconsidered for reintroduction after a follow-up test confirms a drop in antibody levels.
In cases where foods were eliminated specifically as part of an anti-Candida protocol, reintroduction can typically begin after about 4 weeks. These foods should be added back one at a time, every other day, while closely observing for any reactions. This gradual process helps distinguish between foods that now support recovery and those that may still provoke symptoms.

Practical Decision-making

How can I tell if I’m intolerant to foods that aren’t included in the test panel?

You have a few options. First, you can request the premium ImmunoHealth panel, which analyzes immune responses to 180 food antigens. This panel was developed in collaboration with clinical laboratory specialists abroad in response to frequent patient and practitioner requests for broader coverage.
Alternatively, after a period of strict dietary elimination—when the immune system becomes more responsive and your body begins to “communicate” more clearly—you can gradually reintroduce individual foods while observing your body’s response. This approach follows the classic “elimination–provocation” method, a long-standing clinical tool used to detect food sensitivities.
Key indicators to watch for include:
Immediate changes in how you feel after eating (as immunological oxidative responses consume a large amount of oxygen);
Next-day weight fluctuations (immune-mediated inflammation can lead to fluid retention following a significant antibody response).
Both methods offer valuable insights into your body’s tolerance beyond what is captured in the original test panel.

So, if I just eat carrots and cabbage, avoid grains and legumes, and have white meat once a week, I’ll be perfectly healthy? In other words, is diet always the determining factor in disease progression—or are intolerances not always the main obstacle?

Conceptually, the core of the therapeutic approach lies in significantly reducing the overall antigenic burden on the immune system—not limited to dietary antigens alone. Approximately 80% of immune cells reside in the gastrointestinal tract, in constant interaction with the gut microbiota. Without restoring the balance and structural integrity of this microbial biofilm, it is unrealistic to expect recovery of normal intestinal permeability—a key factor in systemic antigen exposure.
A properly selected diet and adherence to the anti-Candida protocol, including targeted food exclusions, are essential components of immune modulation. Without them, the immune system remains overloaded, perpetuating a cascade of inflammatory and metabolic disturbances. This chronic immune strain can contribute to the development of autoimmune and endocrine disorders, compromise anti-tumor immunity, and exacerbate the side effects of standard hormonal therapies often used in treating such conditions.
That said, not all diseases can be reversed by diet alone. Genetically determined or acquired deficiencies may require ongoing medical or replacement therapy. Additionally, not all chronic conditions stem from immune dysfunction.
However, the proportion of patients experiencing marked clinical improvement—or even resolution of symptoms previously deemed untreatable—through a personalized immunomodulatory diet is unmatched by conventional medical statistics. Importantly, this approach also integrates well with traditional treatment modalities when needed, making it a powerful complement to standard care.
