Effect of Personalized Elimination Diet on Food Sensitivity Related Symptoms

Study Purpose

The goal is to identify food sensitivity in patients and assess whether the avoidance of the reaction-inducing foods via an 'elimination diet' leads to improvement in patient symptoms and overall well-being.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years - 65 Years
Gender All

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Food Sensitivity
Additional Details

After seeking appropriate consent, patients' blood samples will be tested for the reactivity toward 262 foods using peptide and protein microarrays. Food protein extraction will be carried out in different solvents such as water and alcohol. The peptide microarrays will synthesize the entire food proteins as peptides in situ while the protein microarrays will test for water-soluble and alcohol-soluble fractions. Thus, food sensitivity testing will be carried out at 3 different levels including water-soluble proteins, alcohol-soluble proteins, and peptides. Patients' blood samples can be tested at all 3 levels or a combination of these. This decision lies at the discretion of the physician. Based on the test results and as per the physician's recommendations, a suitable elimination diet will be suggested to the patient. Personalized diet suggestions for each patient will be made by the physician. The patient will follow the diet for 4 weeks and blood samples will be tested again on completion of the diet, using peptides and protein microarrays. Additionally, based on the physician's recommendations, the time duration for which a patient follows the personalized elimination diet can be modified. The patients will periodically have to fill out diagnostic questionnaires which will help assess the changes in their food sensitivity-related symptoms. Changes in the blood biomarkers and improvement in symptoms will be monitored during the study.

Arms & Interventions


Experimental: Elimination Diet

Participants will be suggested an 'Elimination diet' that will be devoid of the reaction-inducing foods and it shall be followed for 4 weeks.


Behavioral: - Elimination Diet

An 'elimination diet' devoid of the reaction-inducing foods will be suggested for 4 weeks.
