Novel Clinical Trial on Food Sensitivity Testing 

“Personalized Food Elimination Diet: A Clinical Trial Based on Food Sensitivity Assessment” is a 2024 preprint study published in Research Square, conducted by the Vibrant research team. 

The trial aimed to evaluate the effectiveness of personalized elimination diets guided by serological food sensitivity assessments.  

This single-arm, interventional study involved 52 participants aged 18 to 75 who reported gastrointestinal (GI) symptoms. 

The primary objective was to determine whether serological testing for food sensitivities, followed by a personalized elimination diet, would improve participants' symptoms and overall well-being.  

The study specifically aimed to assess changes in GI symptoms, the participants' quality of life, and changes in IgG and IgA antibody levels. 

Our research team recruited participants from eight healthcare practices registered as study sites for this multicenter trial.  

Participant blood samples were tested for IgG and IgA antibodies against 262 food antigens using Vibrant's silicon-based peptide and protein microarray technology.  

Advanced Technology and Personalized Interventions

Our research team conducted the study using the Food Sensitivity Test Complete and our eleven Food Zoomers, which assessed reactions at both the peptide and protein levels. 

Based on test results, we created a personalized elimination diet for each participant, excluding foods they were reactive to.  

Participants followed the diet for four weeks, and their symptoms were monitored weekly using the Food Sensitivity-Symptom Severity Scale (FS-SSS) and the Food Sensitivity-Quality of Life Questionnaire (FS-QoL). Physicians also evaluated participants' responses using the Food Sensitivity-Global Improvement Scale (FS-GIS). 

The primary outcomes measured were the improvement in GI symptoms (as measured by FS-SSS), physician's assessment of participants' responses (FS-GIS), and changes in IgG and IgA antibody levels. Secondary outcomes included the effect of demographic parameters such as BMI, sex, and age on symptom improvement, as well as the impact on participants' quality of life, as measured by the FS-QoL.

Our team assessed symptom changes using the Wilcoxon Signed Rank Test and the Friedman test. Changes in antibody levels were calculated as the percent decrease between pre- and post-intervention concentrations. Demographic effects on outcomes were analyzed using similar statistical methods. 

This robust study design allowed for a comprehensive evaluation of the impact of personalized elimination diets based on precise food sensitivity assessments, providing valuable insights into managing food sensitivities and improving patient health through personalized nutrition. 

Key Findings: Clinical Significance in Managing Food Sensitivity Through Personalized Elimination Diets 

Our clinical trial yielded significant and promising results: 

 One of the primary outcomes was that participants’ GI symptoms were significantly reduced. 

Results showed that 88.46% of participants experienced a significant decrease in symptom severity from baseline to week four. This highlights the positive impact of personalized dietary interventions on GI distress. 

Furthermore, the study assessed changes in IgG and IgA antibody titers, which are crucial markers for food sensitivities. Post-intervention, 96.15% of participants exhibited improved IgG levels, while 84.61% showed a decrease in IgA titers. These findings suggest that the elimination diet effectively reduced the immune response associated with food sensitivities, contributing to improved health outcomes. 

The physicians’ evaluation of participants' responses, gauged using the Food Sensitivity-Global Improvement Scale (FS-GIS), further supported these results. According to FS-GIS scores, 84.61% of participants demonstrated notable improvements. Specifically, 17.31% of participants were rated as significantly improved, 36.53% as moderately improved, and 30.77% as slightly improved. Only a small fraction, 15.39%, showed no change or slight worsening of symptoms. 

Additionally, the study explored the correlation between symptom improvement and demographic factors such as BMI, sex, and age. Both normal weight and overweight groups showed statistically significant symptom reduction from baseline to week four.  

Women experienced significant improvements from weeks one to four, while men showed significant changes starting from week two. These findings indicate that personalized elimination diets are effective across different demographic groups, though the onset of symptom relief may vary. 

Impact on Quality of Life  

Quality of life, measured by the Food Sensitivity-Quality of Life Questionnaire (FS-QoL), improved for 57% of participants. Although the change was not statistically significant for the entire group, the reduction in FS-QoL scores for a majority of participants underscores how addressing food sensitivities can benefit well-being.
