Understand Your Food Responses to Support Long-Term Personalized Nutrition and Health Planning
At VitalLife Scientific Wellness Center, we believe that longevity is not simply about living longer. It is about maintaining good health, quality of life, and the ability to live well for as long as possible. This begins with gaining a comprehensive understanding of each individual’s body and health.
Food is one of the most fundamental factors we are exposed to every day. However, each person may respond differently to different foods. Some people experience noticeable symptoms soon after eating, while others may have chronic, intermittent, or non-specific symptoms that are difficult to link to a particular food.
Food-Related Immune Responses Can Occur Through Different Mechanisms
In general, immune responses associated with food may involve several mechanisms, including IgE, IgG/IgM, Complement, and T-cell responses.
In what is commonly referred to as Food Sensitivity, symptoms are often non-specific and may be difficult to associate with a particular food. These may include bloating, abdominal discomfort, changes in bowel habits, headaches, fatigue, or certain skin-related symptoms. Because these symptoms can have many possible causes, the results should be interpreted together with other relevant health information.
About Food Sensitivity Total IgG
Food Sensitivity Total IgG VitalLife’s Food Sensitivity Total IgG program measures food-specific Total IgG across 232 food items using Immunoblot technology from EUROIMMUN, Germany.
Results are classified into five levels (Class 0–4), from No Reaction to Very Strong Reaction, together with detailed information on the concentration of the response to each individual food item. This helps show individual food-response patterns and provides supporting information for personalized nutrition planning together with clinical assessment.

The key benefit is therefore not simply that the test covers more foods. Rather, it provides physicians with more structured information that can be reviewed together with symptoms, medical history, and individual dietary patterns.
The goal is not to eliminate as many foods as possible but to better understand the body and make more informed, reasonable dietary adjustments.
Benefits from a Longevity Perspective
At VitalLife, Food Sensitivity results are not viewed simply as laboratory numbers. They are considered as one part of a broader health picture that may be evaluated alongside Nutrition, Lifestyle, Metabolic Health, and individual Longevity goals.
This information may help physicians and the healthcare team develop a more structured Personalized Nutrition plan by identifying which foods may warrant further observation, portion adjustment, or evaluation in relation to symptoms, rather than relying on guesswork or unnecessarily eliminating multiple foods without supporting information.
This approach is aligned with the VitalLife Longevity Approach, which emphasizes integrating multiple sources of health information to create individualized, sustainable strategies for long-term health and well-being.
This Test May Be Suitable for Individuals Who
- Experience chronic or intermittent symptoms that may be related to food but have difficulty identifying specific triggers
- Have non-specific symptoms such as bloating, abdominal discomfort, or periodic changes in bowel habits
- Consume a wide variety of foods and would like additional information to support further evaluation
- Want to develop a Personalized Nutrition & Longevity plan
- Want to adjust eating habits in a more structured way under medical guidance
- Prefer not to begin by eliminating multiple foods without supporting information
Preparation Before the Test
- Fasting is not required before the blood test You should not intentionally eliminate foods or make significant dietary restrictions solely in preparation for the test unless otherwise advised by your physician.
- If you are taking regular medications particularly medications that affect the immune system, corticosteroids, or immunosuppressive medications, do not stop taking them on your own. Please inform your physician of all medications you are currently taking and consult with your physician before testing so that the suitability of the test can be assessed on an individual basis.
Important Information and Limitations
- The Food Sensitivity Total IgG test is intended as supporting information for health assessment and nutritional planning. It does not provide a 100% definitive diagnosis and should not be used alone to conclude that a particular food is responsible for specific symptoms.
- Physicians may interpret the results together with symptoms, medical history, dietary history, physical examination, laboratory investigations, and other appropriate assessments in order to support diagnosis and develop an individualized care plan.
- If you have a history of immediate food-allergic reactions, such as hives, swelling of the face or throat, difficulty breathing, or suspected IgE-mediated Food Allergy please inform your physician. Additional allergy-specific evaluation or testing may be required.
FAQ: Food Sensitivity Total IgG
Key information to know before testing and when interpreting your results.
What does Food Sensitivity Total IgG test for?
The test measures food-specific Total IgG across 232 food items using Immunoblot technology from EUROIMMUN, Germany. Results are classified into five levels, from Class 0 to Class 4, with the response value for each food item included in the report.
Is this the same as an IgE food allergy test?
No. IgE-mediated food allergy is commonly associated with relatively rapid symptoms such as hives, swelling, vomiting, difficulty breathing, or anaphylaxis. Food-specific IgG reflects a different immune mechanism and should not replace IgE testing or be used alone to confirm a food allergy.
How are IgG, IgM, and Complement related?
IgG or IgM may be involved in immune complex formation and activation of the Complement System in certain immune mechanisms. However, food-specific IgG results should be interpreted together with symptoms and other relevant clinical information.
Do I need to fast before the test?
Fasting is not required before the blood test. You should not intentionally eliminate foods or make significant dietary restrictions solely in preparation for the test unless otherwise advised by your physician.
How much blood is required, and how long do results take?
Only one tube of blood is required, and the estimated turnaround time is approximately 5 working days.
Can I take the test if I am on regular medication?
Do not stop medication on your own, particularly medications that affect the immune system, corticosteroids, or immunosuppressive medications. Please tell your physician which medications you are taking so the suitability of the test can be assessed individually.
What do Class 0–4 mean?
These classes group the concentration of the food response shown in the report, from Class 0, where no reaction is detected or the result is in the low range, through Class 4, which represents a very strong response. A higher class does not automatically mean that the food must be eliminated.
If a food shows a high response, do I need to stop eating it immediately?
Not necessarily. The goal of the test is not to eliminate as many foods as possible. Results should be considered together with symptoms, medical history, dietary patterns, and your physician’s guidance to determine whether a food should be monitored, reduced, or evaluated further.
Can the test confirm which food is causing my symptoms?
No. The test provides supporting information and does not give a 100% definitive diagnosis. Your physician may consider the results together with symptoms, medical history, dietary history, physical examination, and other appropriate assessments.
Who should speak with a physician before testing?
Anyone with a history of immediate food-allergic reactions such as hives, swelling of the face or throat, difficulty breathing, or suspected IgE-mediated food allergy should inform their physician. The same applies to people taking corticosteroids, immunosuppressive medications, or other medicines that affect the immune system.
