Best Food Sensitivity Test To Take At Home (2023)

Everything We Recommend

Food isn’t supposed to make you feel unwell or give you unpleasant symptoms. If it does, you may have food sensitivities or intolerances you may be unaware of.

Food intolerance (or food sensitivity) is when you have trouble digesting or when your body reacts negatively to particular foods.

At-home tests can identify foods you may be sensitive or intolerant to. With the help of these affordable testing kits, you’ll know which foods to avoid.

More importantly, you can use your test results to improve your digestion and overall health.

Summary

This test, also by Everlywell, allows you to test for even more food sensitivities at 204 foods. This will help you get a better understanding of any other foods you may be reactive to.

It also takes a blood sample and gives you the option of a monthly subscription for support and recommendations.

3. GenoPalate - Health & Nutrition Genetic Profile for Food Sensitivities

Best Food Sensitivity Test To Take At Home (2023) 41

GenoPalate is a unique test that explores your DNA. It finds genetic traits linked to common food sensitivities like lactose, gluten, caffeine, and alcohol.

By using your DNA, you’ll learn more about genetic predispositions that affect your mood, eating habits, food preferences, and nutrient absorption.

GenoPalate also teaches you how you can use nutrition (and certain foods) to manage your stress, optimize your health, and improve your eating habits.

Key Features:

  • Non-invasive DNA testing that requires saliva samples
  • Get your results online in 4 to 6 weeks
  • Tests for 4 common food sensitivities
  • Identifies genetic-based needs for 23 nutrients, including macros
  • Find out if your DNA makes you prone to crave, stress-eat, and more
  • Suggests 100+ healthy foods based on your genetic profile
  • Gain access to a registered dietitian and private support groups
  • Receive nutritional advice for managing stress and improving health
  • Add 5 to 10 personalized recipes to your report ($39.95 to $49.95)
  • GenoPalate doesn’t sell your DNA data to third parties

Food Sensitivity vs. Food Intolerance vs. Food Allergy

Most people use these terms interchangeably. Here are their main differences:1

What Is Food Sensitivity?

Food sensitivities are believed to be an immune response, just like allergies. While your body has a negative reaction to the food, it doesn’t lead to life-threatening symptoms.

Food sensitivities usually cause symptoms that affect your whole body. Signs may appear within minutes up to an hour after eating the trigger food. 

However, some people can take several days before they show symptoms. Because of this delay, it is often left undiagnosed.

A food sensitivity can make you feel uncomfortable and affect your daily routines. But it isn't dangerous.

A food sensitivity test can help you determine what may be affecting you.

What Is A Food Allergy?

Food allergies are an immune reaction to food.

This means your immune system is alerting you to potential danger. When you eat foods you are allergic to, your antibodies (namely IgG) mistakenly view them as a threat and respond appropriately.

Food allergy symptoms appear almost immediately after being exposed to the trigger food. Unlike food sensitivities or intolerances, these symptoms are potentially life-threatening.

What Is Food Intolerance?

A food intolerance is a digestive reaction to food. People with food intolerances lack the enzymes necessary to break down certain foods.

People often confuse food allergies and intolerances to mean the same thing. However, a food intolerance doesn't trigger your immune system like a food allergy. 

It also doesn't always cause symptoms. You can consume a little bit of the trigger food and not have a reaction. When it does, it tends to cause digestive issues several hours after eating the trigger food.

Summary

Key differences among food sensitivity, allergy, and intolerance:

  • Food sensitivity - An immune response, but not a life-threatening one. Mostly just discomfort.
  • Food allergy - A potentially life-threatening immune reaction to foods.
  • Food intolerance - A digestive reaction to foods that disagree with the body but aren't potentially life-threatening.

Should You Get Tested?

If there are foods that make you feel uncomfortable within minutes to hours of eating them, you should consider taking an at-home food test.

What To Do With Your Test Results

At-home tests cannot diagnose food sensitivities, intolerances, or food allergies. But they can help you narrow down “trigger foods” that may be causing your symptoms.

When you take these tests, your results will include information about different foods and how your body reacts to them. You can use this as a guideline for your next steps:

Follow An Elimination Diet

Once you are able to identify your food triggers, you can start an elimination diet.

An elimination diet can help you identify foods you may be sensitive or allergic to and whether you have intolerances to particular foods.

There are two steps to the elimination diet:

  • Elimination Phase: You should stop eating all foods that you’re more likely to react to. You can use your test results to know which foods to avoid.
  • Reintroduction Phase: You can slowly add trigger foods to your diet — but only one at a time. Watch out for symptoms and record them in a journal.

If you react to specific foods, you’d be able to identify your triggers. Wait until your symptoms disappear before reintroducing another food into your diet.

But if you feel fine after eating some foods, they may not be your trigger. Something else is causing your symptoms. You can continue following the diet to find out what they are.

Remember to take note of foods that trigger symptoms and what symptoms you experienced after eating them. It can help your doctor diagnose your condition.

Talk To Your Doctor

After receiving your test results, you can take them directly to a health professional. But you can also wait until you’ve tried the elimination diet before seeking medical advice.

Your doctor can help you interpret your results and recommend any further tests. Currently, there are medical tests for food allergies and sensitivities, but not food intolerances.

Once they have reached a diagnosis, a nutritionist can adjust your diet. Since there’s usually no treatment for these conditions, the goal is to help you avoid future symptoms.

Adjust Your Diet

Now that you know your trigger foods, it’s best that you limit your intake or completely stop eating them. Your doctor can help determine which foods you can eat and avoid.

Generally, you want to stay away from foods that trigger severe allergic reactions.

But if you have mild food allergies, you can undergo a treatment called food desensitization(oral immunotherapy). That way, you can build your tolerance to these foods and reintroduce them to your diet.

You can still eat foods you are sensitive or intolerant to. But you should space them out and only eat them in small quantities. This may reduce your symptoms and give your body time to adjust.

Summary

To identify your food triggers, you need to do the following:

  • Elimination - Eliminate the foods you think are causing negative reactions and take note of how your body responds
  • Reintroduction - Add trigger foods back into your diet one at a time and record all reactions.
  • Consulting your doctor - Talk to your doctor about your findings to determine if you need further testing or special diets.
  • Food limitation or desensitization - Start adjusting your diet or even build your tolerance towards certain foods.

Food Sensitivity FAQs

How Do I Know If I Have A Food Sensitivity?

Keep a list of the food you eat and take note of the symptoms. A food log may help you identify foods that trigger symptoms.

If you experience joint pain, stomach pain, fatigue, rashes, and brain fog — then you may have a food sensitivity. Digestive symptoms may suggest a food intolerance. Meanwhile, itching and swelling may be signs of a food allergy.

You can take food sensitivity tests from EverlyWell to find out. After taking the test, you can take your results to the doctor for further testing.

How Do Food Sensitivity Tests Work?

Food sensitivity tests evaluate your blood sample. They look for a protein called immunoglobulin antibodies. Unlike food allergy tests that look for immunoglobulin E (IgE), food sensitivity tests look for immunoglobulin G or IgG reactivity.

Doctors don’t consider these antibodies to be as reliable when it comes to identifying food allergies or food sensitivities. However, these tests can detect above-normal levels of IgG antibodies after eating certain foods.

Can A DNA Test Identify Food Sensitivities?

Yes. Food sensitivity tests like GenoPalate use DNA samples instead of blood. They can look for genetic markers that increase your risk for common food sensitivities.

Are Food Sensitivity Tests Accurate?

At-home tests that check for food sensitivities can’t be used to diagnose the condition. The same is true for food intolerance and food allergy tests.

That said, they are a great starting point for recognizing trigger foods. You can use your test results to narrow down foods that are most likely to cause symptoms.

For better accuracy, we recommend food sensitivity tests that measure your IgG antibodies — like EverlyWell.

How Much Does Food Sensitivity Testing Cost?

The cost of a food sensitivity test may vary, depending on how comprehensive it is. The best food sensitivity tests on our list cost $79 to $259.

Most at-home food sensitivity tests cost between $200 and $1000.

What Samples Do I Need to Send in for an At-Home Food Sensitivity Test?

The best food sensitivity tests (like EverlyWell) ask for blood samples so they can measure your IgG reaction to different foods. However, some tests use DNA from saliva samples. 

Genetic food sensitivity tests like GenoPalate predict your body’s reaction to foods. They do this by assessing for traits that are associated with common food intolerances.

Does Insurance Cover Food Sensitivity Tests?

Very rarely. Most insurance companies don’t provide coverage for at-home health tests. You have better chances of being covered if you see a doctor to get tested.

You should talk to your doctor or provider to know which tests are covered by insurance because it isn’t always guaranteed.
