A food sensitivity is a type of immune response to specific foods that can cause a wide range of adverse symptoms. You may need to visit a doctor or registered dietitian every 1–2 years, or sooner if you notice changes in symptoms. Storch recommends consulting a healthcare professional before attempting an elimination diet. A healthcare professional can provide recommendations to prevent nutrient deficiencies and guide you as you reintroduce foods to your diet. Notably, food sensitivity tests are not a replacement for a personalized care plan from a registered dietitian or gastroenterologist. The cost of food sensitivity testing is generally not covered by insurance and can range from less than $100 for hair-based tests to $600 or more for blood cell size tests.

There are many companies that offer home testing – either in the form of a kit that can give you an instant result, or by testing samples that you send off. This article reviews the 8 most common types of food sensitivities and intolerances, their related symptoms and foods to avoid. In addition to ruling out other possible causes of your symptoms, such as food allergies or intolerances, a professional can determine the best course of treatment and provide guidance on necessary dietary changes.

Water retention, sluggishness, diabetes, and other conditions can also result from over-eating. The symptoms of allergies and sensitivities include cramping, vomiting, and diarrhea. Allergies are more likely to include hives and rashes among their symptoms, but intolerances can have these symptoms, too.

Food sensitivity or intolerance is inconvenient but not life-threatening. All this is to say that IgG testing for food sensitivities doesn’t tell us much. Since IgG is trained to identify and work against foreign proteins in the body, an IgG test can have a positive result for any foreign protein the body has previously come into contact with.

Allergy Tests vs. Food Sensitivity Tests

Many kits test specifically for levels of antigens such as IgG that may alter after exposure to certain foods. An elimination diet may be best if you have narrowed down your list of potential food sensitivities to no more than five foods. Elimination diets do not necessarily cost anything, but they can be excessively restrictive to follow.

Some people experience stomach pain, gas, and bloating after suddenly increasing their fiber intake. And because it takes some time for the “I’m full” signal from the stomach and intestines to reach the brain, fast eating often triggers overeating, which only compounds that uncomfortable post-meal sense of unease. You stop eating a lot of foods that are perfectly okay for you to eat.

Is There a Best At-Home Food Sensitivity Test? A Dietitian Explains

The naturopath pricked my finger and sent a few drops of my blood off to a lab. During my childhood, my mom took me from one specialist to another. With our new LiveWell with Advocate Aurora Health mobile app, you can manage health and wellness for yourself and for everyone who counts on you. Meanwhile, saliva captured by cheek swabs can be analyzed for genetic testing, but there’s not enough data to support its wide-spread use.

For people who suspect that they may have mild food allergies, an at-home food allergy test can be a convenient first step in identifying potentially problematic foods. For decades, these tests were offered mainly in providers’ offices in alternative medicine settings. Now, they are increasingly available as at-home tests you can purchase online or on drugstore shelves. Manufacturers claim that with several drops of blood or a few plucked hairs, they can identify the foods that are causing your discomfort. Once eliminated from your diet, you’ll be on the road to relief. A blood test may detect your immune system’s reaction to certain meals by measuring immunoglobulin E, an allergy-related antibody .

The results from some assessments are promising, but they’re still in the experimental phase. The best way to know is following an elimination diet under the guidance of your primary care doctor and a registered dietitian. Unfortunately, if you want to do an elimination diet properly, it will take a lot of time and effort. An elimination diet typically involves removing a specific food or group of foods from your diet for a period of time to see how your symptoms might change. In some cases, like if you have a true food allergy, you might have to stop eating that food permanently.

People experiencing an allergic reaction to mangoes may experience symptoms such as a rash and itching. However, some insurance providers may cover the cost of a food test at a doctor’s office. If a person has insurance, they should contact their insurance provider to check which tests they cover. At-home kits for food sensitivity have not been studied extensively enough to prove their accuracy. According to the Asthma and Allergy Foundation of America , approximately 32 million people have food allergies in the U.S. It is not too late to modify your diet and start feeling better, even if you’ve been suffering from an unknown food sensitivity for years.

Or maybe they don’t have a food sensitivity at all—but rather one of the six issues that mimic food sensitivities. Despite my reservations about food sensitivity blood tests, I never start by debunking someone’s test results. That would just make them feel more confused, and possibly alienate them. Alrighty, so let’s circle back to what I started to tell you at the beginning of this article—about the day I underwent food sensitivity testing. Though at-home options like food journaling and elimination diets aren’t as easy as pricking your finger and sending your blood off to a lab, they’re more accurate and effective. Food sensitivities or intolerances are different from food allergies.

In fact, the American Academy of Allergy, Asthma and Immunology recommends against using tests like these to diagnose food allergies, sensitivities or intolerances. Food sensitivities may not be as serious as food allergies, but they can still impact your health and wellness. A food allergy is a serious immune response against a specific food allergen, which usually involves IgE antibodies. If you’re experiencing symptoms after eating certain foods, it’s important to rule out food allergies, which can be more severe than food sensitivities or intolerances. Many people experience food sensitivities, which are immune responses to specific foods that can worsen or trigger a wide range of symptoms .

These are promoted as easy ways to determine exactly what your body is sensitive or intolerant to, and the idea is that you'd then cut these foods out of your diet and feel better. We'll unpack what these tests are, how you use them and if you can trust the results. While this method is super helpful to understand when food intolerance arises, the thing is —you don’t need any testing to take on an elimination diet. They’re no different than the IgG-mediated tests offered in labs and doctor’s offices, meaning that they don’t measure sensitivity, but rather exposure to a given food. The fact that you can do them at home is a good selling point for convenience, but unfortunately, the testing is just not quite there. When our bodies are exposed to a foreign antigen, we create an initial number of antibodies against it, which eventually decreases and stabilizes over time.

However, before we get into the bulk of it, first allow me to introduce myself. Breath tests have been shown to be more accurate in diagnosing lactose intolerance but are not proven to be effective to diagnose other food intolerances. Blood tests look for an antibody called IgG, which our bodies normally produce IgG after eating food. IgG antibodies have not been shown to reliably identify either food allergies or sensitivities. Allergies don’t affect the digestive system but trigger the immune system and can cause heavy breathing and rashes. By contrast, food allergy occurs when the immune system treats certain food as an infection.

Food sensitivity tests also use ALCAT testing to measure the swelling of cells when exposed to certain foods. As of now, no allergy or immunology institution supports the validity of ALCAT testing for diagnosing food allergies or intolerances. In summary, there is not enough evidence to support using food sensitivity tests as a medical practitioner at this time. Food sensitivities are a common factor when it comes to suboptimal health. They are different from food allergies, where individuals usually are presented with immediate and serious reactions to a certain type of food.

Adam’s advice is that these kits are generally quite accurate in what they test, but they are designed to rule OUT coeliac disease, i.e. they can tell you don’t have it, they can’t tell you that you do. Coeliac disease is not an allergy or an intolerance but an autoimmune disease. It causes severe gut problems when people who suffer from it eat gluten, and can lead to damage to the gut lining. Therefore people with coeliac disease need to avoid all gluten for the rest of their lives.
