Do you suspect that your food is causing some health or digestive issues? Do you need to know what foods to avoid to take control of your health?
The best food sensitivity tests can help you determine what foods you should avoid, and this post will help you find the best food sensitivity tests for you.
Food sensitivities can make you miserable and affect your overall health negatively.
Food allergies tend to be obvious. A food allergy can be fatal, but even if it’s not, the symptoms tend to be obvious and severe.
Food sensitivities, on the other hand, are not as obvious. In some cases, people have reacted poorly to a certain food they eat regularly for so long they consider their reaction normal. This makes it challenging for some people to determine whether they have a food sensitivity.
How do I know if I have food sensitivities?
Food sensitivities tend to trigger symptoms that, while not necessarily severe, make you uncomfortable. Some of the most common symptoms of food sensitivities include:
- Bloating and gas after eating. If you feel bloated and uncomfortable or you notice facial puffiness after eating a certain food, it might be a sensitivity. Water retention is a sign of inflammation. Unfortunately, over time, inflammation not only makes you feel uncomfortable, it can damage your health.
- Fatigue and brain fog. Is it tough to get out of bed every morning even if you’ve had enough sleep? Do you feel foggy or out of it for no reason? There are many reasons these things might happen, but a dietary adjustment is a great starting point for helping you remedy the problem.
- Sinus congestion or a runny nose. Congestion is a common sign of a food sensitivity. A lot of people feel “phlegmy” after eating dairy. It might not be full-blown lactose intolerance, but chances are you’re sensitive to eating dairy.
- Upset stomach. A diagnosis of irritable bowel syndrome (IBS) is common when you have frequent, unexplained stomach upset. The truth is, the problem might not be your body, it might be the food you’re eating. Try eliminating any seemingly problematic foods or follow a specific elimination diet and see if your IBS symptoms improve.
- Frequent headaches or joint pain. Pain is a symptom of inflammation. If you have a food sensitivity triggering inflammation, pain in various parts of your body is common. Some of the most common food sensitivities that trigger headaches include: wheat, gluten, and nightshade veggies.
- Skin problems. Rashes and eczema are often linked to inflammation and food sensitivities. Remember, if you try an elimination diet to see how it affects your skin health, it could take a few weeks for eczema and other issues to clear up.
- Asthma and other respiratory symptoms. Food sensitivities prompt your respiratory system to react. Whether you have asthma and certain foods aggravate it or your breathing is more labored after eating certain foods, an elimination diet can help you identify the culprit.
- Weakened immunity. If you catch every head cold and flu that comes down the pike, certain foods could be to blame. Your diet has a significant effect on your immune strength, so dietary improvements should be one of your first moves if you’re struggling with frequent illnesses.

EverlyWell — Food Sensitivity Comprehensive Test
EverlyWell’s Food Sensitivity Comprehensive Test is more thorough than its basic kit. The test checks your IgG reactivity to a wide range of food items, 204 in total. IgG antibodies are released when you eat foods that cause an immune response. This test will check what food antigens your body is reacting to.
The food sensitivity kit measures your results on a class scale of zero to three. Class zero indicates that you’re having a normal level of reactivity to a food item, class one is a mild reaction, class two is a moderate reaction, and class three means a severe reaction. This can be helpful to determine exactly which foods you should stop eating and the foods you don’t need to worry about when beginning an elimination diet.
Key Features:
- Checks 204 different food items for IgG reactivity
- Uses a blood sample to deliver more accurate results than other testing methods
- Results are analyzed and approved by a certified physician from your state

If your goal is to check if you’re sensitive to one of the hundreds of foods they test for, then this is a great option.
What should you look for in a food sensitivity test?
The best and most accurate food sensitivity test is an elimination diet. It requires no special equipment and, for the most part, it costs nothing. You simply stop eating all of the foods you suspect could trigger sensitivity or eliminate foods that are common culprits.
The trouble with an elimination diet is that it takes time and it’s no fun. Eating just a few foods for several days or weeks is boring. It’s challenging to come up with recipes that stimulate your appetite when the foods you’re eating are “boring.” And since you must re-add foods one at a time, it takes forever to get to a varied diet you enjoy.
With an elimination diet, you’ll know what your trigger foods are, but it’ll take you a while to get that knowledge.
This is why so many people opt for a lab test that helps them identify their sensitivities. The tests available include:
Cell-Based Tests
This category includes both Mediator Release Test (MRT) and Antigen Leukocyte Cellular Antibody Test (ALCAT) tests. They assess changes in your white blood cells when exposed to food certain antigens.
Antibody-Based Tests
These tests evaluate your levels of IgG antibodies. They’re most often used to find the causes of symptoms such as IBS and migraines. They are most accurate when the lab performs side-by-side duplicate testing.
Other tests
Muscle response testing, provocation tests, and electrodermal screening are also food sensitivity tests. They require more time than tests that rely on a single blood draw and they are not considered as valid as other types of tests.
Food sensitivity tests may help identify food sensitivities, but factors affect the validity of the test results. Additionally, sensitivities might shift over time. These tests are more convenient than following an elimination diet, but few have been compared in controlled, published studies. Your best bet, if you suspect you have food sensitivities, is to discuss your options with your doctor. At least this way, you’ll know you are trying the right type of test.
Tips for Eliminating Food Sensitivities or Food Allergies
There are a few things you can do to deal with food sensitivities and allergies. Identifying and eliminating the culprit foods from your diet is the best way to improve your health. It’s also a great time to improve your gut health, so your body is running at optimal capacity.
Elimination Diets
An elimination diet is one of the best ways to determine if you have a food sensitivity.
In an elimination diet, you stop eating all foods that could be triggering a reaction.
After your body “detoxes,” (usually about two to three weeks), you gradually add foods back into your diet one at a time. This way you’ll notice when your body reacts. If you return to a food for several days or a week or more and you feel fine, chances are it’s not a trigger.
Most elimination diets take about five to six weeks, but it depends on your specific situation. Some conditions take longer to clear up after you eliminate them from your diet. If you’re going to try an elimination diet, it’s important to customize it to your specific needs so you don’t put yourself through the inconvenience only to learn nothing from the experience.
Once you return foods to your diet, watch for symptoms including:
- Rashes and skin changes
- Joint pain
- Headaches or migraines
- Fatigue
- Difficulty sleeping
- Changes in breathing
- Bloating
- Stomach pain or cramps
- Changes in bowel habits
The foods eliminated during this type of diet include a wide range of options. Some will come as no surprise because they aren’t healthy, but others might surprise some people. It’s important to remember that even the healthiest of foods can be problematic for some people.
Foods eliminated during this type of diet include:
- Citrus
- Nightshade vegetable
- Nuts and seeds
- Legumes
- Wheat, barley, corn, spelt, rye, oats, and bread
- All gluten-containing food
- Processed meats, cold cuts, beef, chicken, and pork
- Shellfish
- Eggs
- Dairy
- Butter, margarine, hydrogenated oils, and mayonnaise
- Coffee, black tea, and all caffeine
- Alcohol
- Soda
- Condiments
- Chocolate
- Desserts and baked goods
- All white and brown sugar, as well as honey, maple syrup, corn syrup, high-fructose corn syrup, and agave nectar
Restoring your gut health
The completion of an elimination diet is a great opportunity to restore gut health. You’ve identified problematic foods and can avoid them. You can also add restorative foods into your diet for a complete overhaul. Other lifestyle changes benefit gut health, too.
To improve gut health, try:
- Adding plenty of polyphenol-rich foods to your diet that are anti-inflammatory, anti-carcinogenic, and antimicrobial
- Get enough sleep with a consistent routine
- Avoid SAD (Standard American Diet) foods
- Practice a consistent exercise routine
- Increase your fiber intake
- Add fermented foods to your diet
- Avoid artificial sweeteners
- Manage stress
- Switch to natural cleaning products
Are At-Home Food Sensitivity Tests Reliable?
Somewhat. They are a great starting point for recognizing food sensitivities. Or, if you’ve done an elimination diet and your results weren’t entirely clear, you can use an at-home food sensitivity test to confirm what you found.
How much does food sensitivity testing cost?
The cost of a food sensitivity test varies a great deal depending on how comprehensive and reliable it is. Most tests cost between $200 and $1000. Insurance rarely covers the cost of these tests.
What Samples Do I Need to Send in for an At-Home Food Sensitivity Test?
Does insurance cover food sensitivity tests?
Very rarely. These tests do not provide the accurate results you get from food allergy tests. Many are at-home tests, so you handle gathering and submitting your sample on your own after you’ve paid for a test kit.
