The ALCAT Food Sensitivity test, more formally is a leukocyte (white blood cell) activation test that analyzes direct, pro-inflammatory cellular responses of the innate immune system.
What is the difference between a sensitivity, allergy and intolerance? The main pivot point between them is whether the immune system is activated.
Food Allergy: Food allergy is an immune-mediated reaction to the food. The most common is an immunoglobulin E (IgE)-mediated reaction. IgEs are allergic antibodies. They cause an immediate reaction when chemicals, like histamine from mast cells, are released. Food allergies can be fatal, unlike a food intolerance or sensitivity. In extreme cases, ingesting or even touching a small amount of the allergen can cause a severe reaction such as hives, anaphylaxis, etc..
Eight foods account for 90 percent of allergic reactions: milk, eggs, fish, shellfish, peanuts, tree nuts, wheat, and soybeans.
There are also non-IGE mediated food allergies. These reactions occur when other parts of the immune system are activated apart from IGE antibodies.
Food intolerance: which are also not immune mediated and are due to the inability to process or digest a food. you may be able to eat small amounts of the offending food without trouble, Causes of food intolerance include:
Food Sensitivity: A food sensitivity is harder to identify than a food allergy since the immune response can be delayed. Symptoms may surface hours, days, or weeks after the food exposure. Symptoms are not severe and may not be gut-related, so you might not make the connection right away.
Food sensitivity is generally thought to be an immune-mediated reaction to a food (different than an intolerance). And food sensitivities are different than food allergies, which involve IgE antibodies. With food sensitivities, the immune system makes antibodies against foods such as IgG, IgA, or IgM (immunoglobulins G, A, or M) and these can be measured with blood tests. Antibodies are made by the immune system and are proteins that your immune system uses to fight infections caused by viruses or bacteria. If the same infection enters your body in the future, it will help to protect you against it. Antibodies can be made against other foreign materials such as pollen, dander, dust, or foods.
Leaky gut and food sensitivities are two sides of the same coin. Unfortunately, if you have autoimmunity, there is a good chance you also have a leaky gut (also known as intestinal permeability). The lining in your gut is very thin, but strong, that is until it opens somehow. Normally, your gut lining will protect you from all kinds of bacteria, toxins, and undigested food particles.
When your gut lining is unhealthy, it can develop little holes in the intestinal wall. This can allow undigested food, bacteria, and toxins to escape the gut and enter the bloodstream – triggering inflammation. Leaky gut can change your gut flora (the good bacteria that live in your gut) and worsen inflammation. Intestinal permeability can be a feature of some conditions including celiac disease, Crohn’s disease, IBS (irritable bowel syndrome), and is associated with autoimmune disorders (especially lupus, type 1 diabetes, and multiple sclerosis).
Your immune system exists to protect you from invaders. The things that mistakenly pass through a leaky gut lining are considered to be dangerous invaders by the immune system and it reacts. Your immune system has an immune memory (creating memory cells for these proteins or undigested foods) – it will react to the invaders it remembers, such as foods that your body is sensitive to. Each time your body is exposed to a certain food protein, it will remember it and react by sending your antibodies to fight it. What Are the Most Common Food Sensitivities?
First of all, this is an extremely individualized question. Everybody’s diet and sensitivities to foods are personalized as well as their reactions. Common food sensitivities include dairy, grains such as wheat or corn, and soy.
Gluten or wheat – Celiac disease is an autoimmune disease, not a food sensitivity, that is triggered by gluten and causes damage to the small intestine. Non-celiac gluten sensitivity (NCGS) occurs when a person gets symptoms from eating gluten, but they don’t experience the tissue damage, immune response, or diagnostic test results that are characteristic of celiac disease. Common symptoms of NCGS include brain fog, joint pain, headache, numbness in legs, arms, or fingers. People can also have sensitivities to other components of wheat (not gluten) or wheat allergy. We often see gluten or wheat sensitivities in Hashimoto’s disease.
Dairy – dairy sensitivity is an immune response to one or more milk proteins found in cow’s milk. Dairy sensitivity may show up as constipation, diarrhea, headaches, congestion, ear infections, and more. Other common food sensitivities are grains (especially corn), soy, and eggs.
Synopsis of IGg testing: Food sensitivity tests typically look for the presence of IgG (not IgE). IgG antibodies have not been shown to reliably identify either food allergies or sensitivities. Most people produce IgG antibodies after eating food. They are not specific to a person’s sensitivity, although past or frequent exposure to a food may cause these levels to be higher.
Because IgG blood tests have not been proven to identify food sensitivities or allergies, there is a lack of evidence to support making changes based on their findings. The restrictions suggested by IgG test results may lead you to unnecessarily avoid healthy foods. Or, they may prompt individuals with food allergies to include foods that could be harmful to them.
Contemporary research suggests that the presence of IgG antibodies indicates exposure and tolerance. IgG4 antibodies may actually help sustain tolerance to a food or compound
