Do you ever feel like you may have certain symptoms related to foods, such as headaches, stomach pain, diarrhea, or fatigue? Do you feel you may want to try eliminating possible triggers, but you are not sure where to start?

Our Food Sensitivity test measures your body's IgG immune response to 96 foods that are commonly found in western diets.

An improvement in food sensitivity symptoms after eliminating the triggering food source is always the best test. Rather than randomly eliminating foods over many months and assessing your change in symptoms, you can have a directed elimination plan. An antibody IgG immune response can offer guidance on what foods may be the best to eliminate temporarily, then complete an add back challenge to identify symptom producing foods. Note that this test is not a food allergy test, which measures severe allergies that can be life threatening conditions. Food allergy tests measure IgE antibodies and can't be currently taken at home. This test also cannot diagnose Celiac Disease.

Food can trigger an immune response which may manifest itself in physical symptoms such as:

  • Dry and itchy skin
  • Other miscellaneous skin problems
  • Food intolerance
  • Feeling bloated after eating
  • Fatigue
  • Joint pain
  • Migraines
  • Headaches
  • Gastrointestinal (GI) distress
  • Stomach pain

If you are looking to add a potentially ‘problematic’ food back into your diet to see if you’re still sensitive to it on your test results, it’s recommended to consume that food for about 4 weeks prior to testing. Please be advised that if you experience symptoms while eating this food, you’ve already identified a sensitivity.

Our food sensitivity test is highly accurate and can detect low levels of IgG reactivity.

IgG antibodies are generated in response to a trigger but are continuously metabolized (broken down) by the body; therefore, individuals who have since eliminated triggering foods from their diet may not have any elevated IgG reactivity to report. Additionally, foods that are not regularly eaten for any reason may not have any elevated IgG reactivity to report above "low reactivity". This does not mean that an IgG response to the triggering food was never present.

You may have an elevated reactivity to a food that you do not consume, which could be the result of cross reactivity to other substances you are exposed to in the environment or as a result of ingesting ingredients that you did not realize were actually in a food (for example, in a processed food).

Your food sensitivity results will tell you how reactive your IgG antibodies are to 96 foods commonly found in western diets.

Each food will be rated on a Class scale of 0-3: Class 0 (low reactivity) to Class 3 (high reactivity). This is a great place to start if you want to dig into your body's relationship with food.

You will also get:

  • Tailored suggestions about what to do next
  • Help prioritizing your trial elimination diet
  • Personalized information and education

EverlyWell will provide tailored suggestions about what to do next. While reactivity does not always equate with symptoms, it can help prioritize the foods selected for a trial elimination diet. Once you have your IgG test results, you can try an elimination diet of your choosing until you achieve the right balance of minimizing your symptoms while maintaining a lifestyle that you enjoy.

You may choose to not stop eating certain foods, but knowing your reactivity might lead to adjustments in how much or frequently you eat them.

Our tests provide personalized information and education; they are not intended to diagnose any disease or condition or to substitute for professional medical advice or treatment. You should always seek the advice of your physician or other qualified health care provider with any questions you have regarding your medical care.

This test is a great place to start if you want to dig into your body's relationship with food and is generally more affordable than comparable tests. Enjoy food sensitivity testing the way it should be; quick, easy, and from the convenience of your home. If you have any questions feel free to chat with us below.

Your body can react to a “troublesome” food in several different ways. How your body reacts to that food depends on whether you have a food sensitivity, food intolerance, or food allergy. Here, we’ll explore each of these types of reaction to food – starting with food sensitivity.


Food Sensitivity

A food sensitivity may result from a type of immune system response that’s very different than a food allergy. While not entirely understood, research has shown that people can identify symptom-causing foods using the results of IgG testing. IgG antibody reactions against those foods may be normal in some people, but in others it can cause symptoms because of the inflammation the immune reaction produces from those interactions. Food sensitivity symptoms can include acne, brain fog, dry and itchy skin – and much more.

What’s really interesting about food sensitivities is that symptoms usually don’t appear as soon as you eat the problem food. Instead, you might have symptoms hours or days after eating that food – which can make it hard to connect specific foods to the symptoms you’re experiencing.

Fortunately, with an elimination diet and EverlyWell’s Food Sensitivity Test, you can discover what foods you may be sensitive to.

Food Sensitivity Explained
Food Allergy vs. Food Sensitivity



Food Allergy

When you eat a food you’re allergic to, your immune system responds by activating the IgE antibodies in your blood. Those antibody-food interactions result in the production of a chemical called histamine. Histamine is a type of substance your immune system makes. When immune cells release histamine in your body, you might experience any number of allergy symptoms. (That’s why many over-the-counter allergy medications are known as “antihistamines” – they counteract the allergic effects of histamine.) With food allergies, symptoms usually appear almost as soon as you’ve eaten the trigger food.

An example of a food allergy is an allergy to tree nuts, one of the most common causes of food-related allergic reactions in the world. (Hazelnuts, walnuts, and macadamia nuts are all examples of tree nuts.)

If you’re allergic to a certain food, you can experience a potentially life-threatening allergic reaction whenever you eat that food. That’s because anaphylaxis can occur within minutes of consuming food allergens. Anaphylaxis can result in death because of a dramatic drop in blood pressure – or because of swelling around the person’s airways, which cuts off the body’s supply of air.


Food Intolerance

A food intolerance can occur if, for example, you don’t have enough of the right enzymes your body needs to break down a particular food. (Enzymes are special proteins in the body that dramatically speed up chemical reactions.)

An example of a food intolerance is lactose intolerance. Lactose is a type of sugar commonly found in cow’s milk. If you’re lactose intolerant, your body doesn’t produce enough lactase – the enzyme that breaks down lactose. So it’s hard for your body to digest lactose effectively, resulting in unpleasant symptoms when you drink a glass of milk or eat dairy products. Food intolerance symptoms commonly include nausea, bloating, and diarrhea.

Unlike food allergies, food intolerances don’t involve an immune system response - they all take place inside the gut before digestion occurs.

If you have a sensitivity to a particular food, you might experience one or more symptoms several hours or days after eating that food. These symptoms can include:


  • Acne
  • Brain fog
  • Eczema
  • Dry and itchy skin
  • Bloated stomach after eating
  • Fatigue
  • Joint pain
  • Reflux
  • Migraines
  • Diarrhea
  • Depression and mood swings
  • Runny nose
  • Headache
  • Trouble sleeping
  • Dark circles under eyes

An elimination diet can be a useful tool for uncovering the specific foods you’re sensitive to.

Basically, in an elimination diet, you temporarily remove foods from your diet that you suspect could be giving you symptoms. In other words, you stop eating those “suspect foods” for a given amount of time – often about 4 weeks.

Next, you add those foods back to your diet – one at a time. Each time you add a “suspect food” back to your diet, you watch for symptoms for about 2-3 days. If a food you’re adding back doesn’t result in symptoms, then you continue eating it as a normal part of your diet. But if a food does give you symptoms when you add it back to your diet, then you’ve likely found a food you’re sensitive to.

Elimination diets, though, can be a tedious process. It’s largely a guessing game because during the initial “food removal” phase of the elimination diet, you have to guess what foods could be giving you symptoms.

That’s why food sensitivity testing can make a real difference if you want to discover the foods you’re sensitive to. A food sensitivity test checks the reactivity levels of your IgG antibodies for many different foods. (IgG antibodies are another type of antibody that your immune system produces.)

If you have a high IgG reactivity level to a certain food, there’s a possibility that food may be involved with causing your food sensitivity symptoms.

So taking a food sensitivity test can give you a list of “suspect foods” that’s based on your body’s immune system response. You can then use this information to guide your elimination diet – and to choose what foods to eliminate at first. This helps remove a lot of the “guessing” in the elimination diet process – and can make it easier for you to pinpoint the foods behind your symptoms.

How To Use A Food Elimination Diet To Discover Your Food Sensitivities

How does a food sensitivity blood test work?

A food sensitivity blood test measures your IgG reactivity levels for different kinds of food, using a small sample of blood. High IgG reactivity for a certain food indicates there’s a possibility that food may be involved with causing your symptoms.

Knowing your IgG reactivity levels for various foods can help you create a list of “suspect foods” to initially remove in an elimination diet – making it an easier, quicker process to pinpoint the exact foods that cause you symptoms.


What is an IgG test?

An IgG food sensitivity test uses a small sample of blood to check how your IgG antibodies react to different kinds of food. A higher IgG reactivity level for a certain food can mean that there’s a possibility that food can be giving you symptoms – making that food an ideal candidate to include in your list of “suspect foods” you initially remove in an elimination diet.


IgG food sensitivity testing accuracy

An IgG blood test for food sensitivity reveals your IgG reactivity levels for different foods. A higher level of IgG reactivity for a given food suggests that it may be causing your symptoms.

However, higher IgG reactivity levels don’t always correlate with symptom-causing foods – which is why it’s so important to use an elimination diet (guided by your IgG test results) to accurately pinpoint your specific food sensitivities.


How to test for food allergies?

Food allergy testing is usually done under medical supervision because severe allergic reactions can occur during the test. A common type of food allergy test is the skin prick test (or SPT). For this kind of test, an allergist injects tiny doses of food on a small area of your skin. You’re then monitored for signs of an allergic reaction, such as hives.

However, the skin prick test isn’t the only way food allergy testing is done.


What are the different ways of testing for food allergies?


  1. Skin prick test
  2. In a skin prick test, which is done under medical supervision, an allergist injects different types of food on small areas of your skin. If you experience allergy symptoms when a particular food is applied to your skin, then you’re likely allergic to that food.


  3. Blood test for food allergies
  4. In a food allergy blood test, a blood sample is drawn from a vein in your arm. A lab then measures food-specific IgE antibodies in this blood sample to identify likely food allergies. IgE antibodies are produced by the immune system when it detects an allergen in your bloodstream.


  5. Oral food challenge
  6. In an oral food challenge – also conducted under medical supervision – you begin by ingesting a very small amount of a particular food (such as a teaspoon of milk). Next, you gradually consume larger and larger amounts of that food until allergy symptoms occur.


How much does a food allergy test cost?

How much is an allergy test? That depends on many factors, such as the type of allergy test, the number of foods tested, and more. So unfortunately there’s no straightforward answer to this question.

Note that EverlyWell’s Food Sensitivity Test is NOT an allergy test. Allergy testing generally requires medical supervision because the test can trigger allergic reactions that are very severe – and even fatal.

EverlyWell’s Food Sensitivity Test will not tell you what foods you’re allergic to. Instead, it will tell you what foods you may be sensitive to, which can help guide your elimination diet. Food sensitivities can result in a number of very unpleasant symptoms (such as migraines, acne, and more), so discovering what foods you’re sensitive to can put you on a path towards greater well-being.


How to test for food intolerance?

The most reliable food intolerance test is an elimination diet. First, you remove foods from your diet that you think could be behind your food intolerance symptoms. If your symptoms improve during this phase of the elimination diet, then one (or more) of the foods you removed is likely responsible for your symptoms.

Next, you gradually add those foods back to your diet to see if your symptoms reappear when any specific foods are added back to your diet.


Is there a food intolerance blood test?

There currently isn’t a reliable food intolerance blood test. Instead, elimination diets are commonly used. Breath tests can also be useful for detecting some forms of food intolerance – specifically, carbohydrate malabsorption (difficulty digesting carbohydrates, like lactose).
