Triggers and Tests Unveiled
Understanding types of food allergies and sensitivities and identifying potential triggers is crucial for managing these conditions effectively. Fortunately, advancements in medical technology have led to the development of various tests to help individuals identify their specific food triggers. This article will explore the difference between food allergies and sensitivities, foods that can trigger allergies and some available at-home testing options. Consider using 5Strands and Viome; they are two different companies that offer personalized health insights through testing, with 5Strands focusing on food sensitivities and intolerances, while Viome specializes in gut microbiome analysis for dietary recommendations and wellness.
Common Food Allergies/Triggers
Several foods are commonly associated with allergies. Here are some of the more prevalent food allergies.
- Peanuts and Tree Nuts: Peanuts, almonds, walnuts and cashews are among the most common triggers.
- Shellfish: Shrimp, crab, lobster and other shellfish can cause allergic reactions.
- Milk: Cow's milk and dairy products are frequent allergens, especially in children.
- Eggs: The protein in eggs can trigger allergies, most commonly in young children.
- Soy: Soy-based products can lead to allergic responses.
- Wheat: Wheat allergy is distinct from gluten intolerance or celiac disease.
- Fish: Some individuals may be allergic to specific types of fish.
Understanding Food Allergies
A food allergy is an immune system response triggered by consuming certain foods. When a person with a food allergy ingests the offending food, their immune system perceives the protein as harmful. It releases antibodies, particularly immunoglobulin E (IgE), to fight off the "invader." This immune response leads to the release of histamine and other chemicals, causing a range of symptoms that can be mild to severe and even life-threatening.
Common symptoms of food allergies include hives, itching, swelling of the face or throat, difficulty breathing, abdominal pain, diarrhea and, in severe cases, anaphylaxis, which is a potentially life-threatening reaction that requires immediate medical attention.

Understanding Food Sensitivities
On the other hand, food sensitivity is a broader term encompassing various adverse reactions to certain foods. Unlike food allergies, which involve the immune system, food sensitivity primarily involves the digestive system and does not trigger an immune response. This makes it less severe than food allergies but can still cause discomfort and affect a person's well-being.
Common symptoms of food sensitivity include bloating, gas, diarrhea, constipation, headaches, skin rashes and fatigue. It is important to note that the onset of symptoms may be delayed, making it challenging to pinpoint the specific trigger.
Tests for Food Allergies and Sensitivities
If you suspect you may have a food allergy or sensitivity, many at-home testing kits are available. Here are some of the more popular options.
Everlywell
Everlywell offers a comprehensive Food Sensitivity Test that examines IgG antibody reactions to various foods. The test is done at home through a simple blood sample and assesses the body's immune response to over 100 different food items. Once the results are obtained, individuals can work with healthcare professionals or nutritionists to create personalized elimination diets to avoid triggering foods.
Check My Body
Check My Body is another at-home testing service that provides comprehensive health analysis. They offer food sensitivity testing, which involves sending a hair sample to their laboratory. The test examines the body's reactions to a wide range of food items and provides insights into potential intolerances.
5Strands
5Strands provides food sensitivity testing using hair samples to identify potential intolerances to certain foods and environmental factors. Their comprehensive tests can help individuals make informed decisions about their diet and lifestyle.
York Test
The York Test is a laboratory-based test allergy that measures IgG antibody reactions to specific food and drink ingredients. A blood sample is taken, and the test covers an extensive range of items. The results are presented in an easy-to-understand format, highlighting the severity of the reactions, and offering personalized advice on dietary changes to manage sensitivities effectively.
Final Notes
Food allergies and sensitivities are increasingly common health concerns affecting millions worldwide. These adverse reactions to specific foods can cause a range of symptoms, from mild discomfort to severe, life-threatening reactions.
Food allergies and sensitivities can significantly impact a person's quality of life and require careful management. Understanding the distinction between food allergies, which involve the immune system, and food sensitivities, which primarily affect the digestive system, is crucial for appropriate treatment and dietary adjustments. If you suspect you have a food allergy or sensitivity, it is essential to consult a healthcare professional before undergoing any testing or making drastic changes to your diet. These at-home tests can provide useful insights, but they should be different from medical advice and diagnosis.
