At-Home Food Sensitivity Tests Help Identify Problem Foods – Use Your Results To Guide a Temporary Elimination Diet To Confirm Food Intolerances

by | May 3, 2023 | Wellness Blog: Food Sensitivity

at-home food sensitivity test, symptoms stomachache Food sensitivity is a growing concern for many people. A sensitivity occurs when a certain food prompts the immune system to create internal inflammation, which can cause a range of symptoms, from mild to severe, including joint aches, chronic congestion, chronic skin rashes, bloating, constipation, diarrhea and migraine headaches1. Identifying problem foods is often a trial-and-error process that can be time-consuming and frustrating. However, an at-home IgG food sensitivity test can provide insight into which foods might be causing problems, and can guide a temporary elimination diet to help alleviate symptoms2.

4U Health’s at-home food sensitivity tests are easy to use and provide results in just a few days. They require a small blood sample, which is collected through a finger prick, and analyze for specific IgG antibodies that are often associated with food sensitivities. These tests can help flag potential intolerances to a range of foods, including beef, corn, dairy, eggs, gluten, lamb, peanuts, pork, shellfish, and soy, among others3.

Once you receive your results, it’s important to understand what they mean. Each test will show which foods you may be sensitive to and to what degree. The test report ranks each food on a Class scale from 0-4; Class 0 (normal reactivity) thru Class 4 (very high reactivity). Test findings can provide valuable clues as to which foods you may not tolerate well.

After you receive your results, it’s recommended to use them to guide a temporary elimination diet to confirm your problem foods. A targeted elimination diet involves removing up to four foods at a time from your diet that flagged positive on your report, typically for three to four weeks. During this time, you should pay close attention to any changes in symptoms (i.e., did they improve?).

After the elimination period, you can slowly reintroduce the eliminated foods one at a time, monitoring for any symptoms that may arise. This process can help you identify which foods are causing problems, and which ones can be safely reintroduced into your diet.

It’s important to note that at-home food sensitivity tests are not a definitive diagnosis of food intolerances on their own. They can provide helpful information as a first step to identifying food culprits that may be giving you symptoms, but should be used in conjunction with a targeted elimination diet along with medical advice from a healthcare professional for a definitive diagnosis.

4U Health offers three great choices for IgG food intolerance tests.

Comprehensive Food Sensitivity Test, 240 Foods: Ideal for people who consume a broad-based diet.

Vegetarian Food Sensitivity Test, 198 Foods: Tailored for people who consume a plant-based diet.

Essential Food Sensitivity Test, 96 Foods: Targets a select set of common foods and spices that often cause intolerances.

In conclusion, at-home food sensitivity tests can be a useful tool in identifying problem foods and guiding a temporary elimination diet to confirm your intolerances. These tests are a good first step toward trying to improve your overall health and well-being.
