1. Understanding Food Sensitivity: More Than Just IgG Reactions
What exactly is food sensitivity, and how does it differ from other food-related issues?
Food sensitivity differs from food allergies and intolerances. Food intolerance is often genetically driven, like celiac disease or lactose intolerance, while food allergy involves an immediate immune response, such as with peanuts. Food sensitivities are less clear-cut, often involving delayed reactions to foods that were once tolerated, and can fluctuate based on overall health.
2. Why IgG-Based Food Sensitivity Tests May Not Be the Answer
Are IgG food sensitivity tests a reliable way to determine what foods to avoid?
IgG-based food sensitivity tests aren’t always reliable. Immunoglobulin G (IgG) is the most common antibody in blood circulation. According to research from the University of California, Berkeley, in July 2025, the presence of IgG antibodies indicates what you have been eating, not necessarily what you should avoid. Dr. Aaron, head of research at Gene Food, is skeptical of IgG tests due to their lack of scientific rigor. At larosafoods.com, we emphasize understanding the limitations of these tests.
3. What Steps Should You Take Before Food Sensitivity Testing?
What steps should you take before investing in food sensitivity testing?
Before spending money on food sensitivity testing, rule out food allergies and intolerances. Food allergy and intolerance elicit different reactions than sensitivities, so it’s crucial to address these foundational issues first. You can find valuable resources on distinguishing between allergies, intolerances, and sensitivities at larosafoods.com.
4. How Can You Rule Out Allergies and Intolerances?
How can you effectively rule out allergies and intolerances before addressing sensitivities?
To rule out allergies and intolerances, start with these tests:
- Test for genetic wheat sensitivity.
- Test for genetic lactose intolerance.
- Test for IgE-mediated food allergy.
- Test for histamine intolerance.
At larosafoods.com, we provide detailed information on each of these tests and how they can help you pinpoint the root causes of your food-related issues.
5. What Role Does Histamine Intolerance Play in Food Sensitivity?
What role does histamine intolerance play in the context of food sensitivities?
Histamine intolerance is increasingly common in adulthood and can cause “moving target” food sensitivities. This means you might react to certain foods sometimes but not always, depending on your histamine levels. The American Journal of Clinical Nutrition published a paper on this topic that anyone suffering from mysterious food sensitivity should read. Explore articles at larosafoods.com to understand how histamine impacts your digestive system and overall health.

Discover your ideal diet type and personalized nutrition plan at larosafoods.com.
8. Why Should You Be Cautious About Direct-to-Consumer Microbiome Tests?
Why is it important to approach direct-to-consumer microbiome tests with caution?
Direct-to-consumer microbiome products often have more hype than science. For example, one personal experience with Viome showed conflicting TMAO results and vague advice to avoid certain plant foods due to “plant virus.” Visit larosafoods.com for reliable information and resources on gut health and nutrition.
9. The Importance of Addressing Root Causes Instead of Just Managing Symptoms
Why is it essential to address the root causes of health issues rather than merely managing symptoms?
If there is “nothing” you can eat, look for a root cause upstream from food sensitivity. Conditions like undiagnosed celiac disease can render food sensitivity testing useless until the underlying health issue is addressed.

FAQ: Navigating Food Sensitivity Testing
1. What exactly is a food sensitivity test?
A food sensitivity test aims to identify foods that may be causing adverse reactions in your body, leading to symptoms like digestive issues, skin problems, or fatigue. However, it’s essential to understand that not all tests are created equal, and some may not provide accurate or reliable results.
2. How do IgG food sensitivity tests work?
IgG food sensitivity tests measure the levels of IgG antibodies in your blood in response to different foods. The idea is that elevated IgG levels indicate a food sensitivity. However, many experts argue that IgG antibodies simply indicate exposure to a food, not necessarily an adverse reaction.
3. What are the limitations of IgG food sensitivity tests?
The American Academy of Allergy, Asthma & Immunology and other medical organizations do not recommend IgG food sensitivity tests due to a lack of scientific evidence supporting their accuracy and clinical relevance. These tests often produce false positives, leading to unnecessary dietary restrictions.
4. What is the difference between food allergy, food intolerance, and food sensitivity?
Food allergy involves an immediate immune response, often with severe symptoms. Food intolerance is usually a digestive issue, like lactose intolerance. Food sensitivity is a broader term that can encompass various delayed reactions to foods. Understanding these differences is crucial for choosing the right tests and treatments.
5. Are there any reliable food sensitivity tests?
Some alternative tests focus on identifying food allergies (IgE-mediated) or intolerances (like lactose intolerance). Genetic testing can also reveal predispositions to certain food sensitivities. However, it’s essential to consult with a healthcare professional for proper diagnosis and guidance.
6. How can genetic testing help with food sensitivities?
Genetic tests can identify predispositions to conditions like celiac disease, lactose intolerance, and histamine intolerance. For example, the AOC1 gene, responsible for producing diamine oxidase (DAO), can indicate how well your body clears histamine. At larosafoods.com, we delve into the genetic factors influencing your diet and provide customized nutrition plans.
7. What is histamine intolerance, and how is it related to food sensitivities?
Histamine intolerance occurs when your body can’t break down histamine properly, leading to a build-up that causes symptoms like headaches, digestive issues, and skin problems. Certain foods are high in histamine or can trigger histamine release, exacerbating these symptoms.
8. How does gut health impact food sensitivities?
An imbalanced gut microbiome can contribute to food sensitivities. Conditions like SIBO (Small Intestinal Bacterial Overgrowth) and IBS (Irritable Bowel Syndrome) can disrupt digestion and increase reactivity to certain foods. Maintaining a healthy gut is crucial for managing food sensitivities.
9. What are some alternative approaches to identifying food sensitivities?
Instead of relying solely on IgG tests, consider elimination diets, where you remove suspected foods and gradually reintroduce them to monitor your body’s response. Working with a registered dietitian or nutritionist can also provide personalized guidance and support.
