Fortunately, once you’ve narrowed down the foods that are causing your woes, eliminating them from your diet allows your body to heal and have you feeling back to normal. However, figuring out what foods you’re sensitive to usually involves a long and difficult process of slowly eliminating items from your diet – called an elimination diet – and seeing if it helps. 

Unless you take a food sensitivity test that is.

Many DNA testing companies can analyze a sample of blood, saliva, or hair to help narrow down the foods you’re reacting to. These tests are easy to take and can be done from the comfort of home. Then problem is, there are tons of them out there, and many aren’t that great. So we set out to try the most popular options on the market to find the top food intolerance tests so you can get back to feeling like yourself again.

EverlyWell — Food Sensitivity Comprehensive Test


7 Best Food Sensitivity Tests to Take Control of Your Health 1

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 two is a mild 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
  • Includes actionable report that can be used to design an elimination diet plan
  • Report available online within days after your sample has been received by EverlyWells CLIA-certified labs

Each test, while similar, has something unique to offer. For example, EverlyWell offers a comprehensive test that gives you accurate results for up to 204 different foods and not too much else. 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. 

If you're looking for a test that covers more, including heavy metals, pet dander, and environmental factors, 5Strands and Modern Allergy Management’s tests may be what you're looking for. However, if you want some actionable diet suggestions, including the foods you should be eating on top of those to avoid, check out BodyHealth IQ’s test.
