• inFoods IBS Provides Personalized Diet Therapy for Patients Suffering with Irritable Bowel Syndrome (IBS)
  • Research Finds Patients Following a Personalized Diet Therapy Created with inFoods ® IBS, Experienced Reduced Abdominal Pain and Bloating

IRVINE, Calif., Feb. 19, 2025 (GLOBE NEWSWIRE) -- Biomerica, Inc. (Nasdaq: BMRA), a global leader in advanced medical diagnostic solutions, is proud to announce that patients with Irritable Bowel Syndrome (IBS) may experience significant relief from abdominal pain when following a dietary therapy created and guided by the inFoods ® IBS blood test. The findings from a clinical trial published in Gastroenterology , demonstrate that participants who adhered to a personalized diet therapy based on the test results experienced greater symptom improvement compared to those following a sham (placebo) elimination diet.

The inFoods ® IBS test was designed specifically for IBS patients. It identifies individual foods that trigger an elevated (above normal) Immunoglobulin G (IgG) antibody responses—which is a marker of inflammation associated with IBS symptoms. Every food in the inFoods IBS panel is set with a 95% confidence interval cutoff to provide accurate results. No other IBS product has this technology.

Irritable bowel syndrome (IBS) affects an estimated 10% to 15% of adults in the United States and is known to significantly reduce quality of life and work productivity. The condition presents a range of symptoms, including abdominal pain and cramps, which can be exacerbated by consuming certain foods.

“We have patients all the time who say, ‘I know food is a problem for me. Is there any way to figure out which foods I'm sensitive to?’” said Prashant Singh, MBBS, Michigan Medicine gastroenterologist and lead author on the paper.

Study Design and Key Findings

The randomized, multicenter, double-blind, placebo-controlled trial enrolled 238 IBS patients across eight leading academic centers in the U.S. Each participant was tested for IgG antibody responses to 18 common IBS trigger foods using the inFoods IBS ® product. Patients were then randomly assigned to one of two groups:

  • The treatment group eliminated actual foods identified by the inFoods test as triggering an abnormally high IgG antibody immune response in that patient.
  • The control group (placebo) followed a sham diet that removed foods for which the patient tested negative with the inFoods IBS test and consumed in a similar amount, (e.g., if a patient tested positive for walnuts, they were instructed to eliminate almonds from their diet).

The study found that 59.6% of patients in the treatment group of the study, and who eliminated their identified trigger foods, met the FDA-standard target for abdominal pain reduction, compared to 42.2% in the control group . Notably, the benefits were most pronounced in patients with IBS-C (constipation-predominant IBS) and IBS-M (mixed constipation and diarrhea). 67.1% of IBS-C patients in the treatment group met the FDA target for reduction in pain , versus 35.8% in the control group . 66% of IBS-M patients in the treatment group experienced a reduction in pain that met the FDA target , compared to 29.5% in the control group.

“Patients had done all sorts of IgG antibody testing before, and it wasn’t very reliable. This latest test is supported by science. I can refer patients to this IBS-specific antibody testing, after explaining the science and the limitations of the study,” said Dr. Prashant Singh, MBBS.

A Personalized, Targeted Approach to IBS Management

While prior research suggested a potential link between IgG antibody responses and IBS symptoms, previous studies faced limitations such as small sample sizes, IgG tests not adequately designed for patients with IBS, single-center trials, and a lack of well-designed control diets. The inFoods ® IBS study was specifically designed to overcome these shortcomings.

“One of the key challenges in past studies was distinguishing normal IgG responses from those that may contribute to IBS symptoms,” Singh explained. “This research takes a targeted approach by using an IBS-specific IgG test to personalize dietary recommendations.”

Compared to pharmaceuticals, personalized elimination diets offer a proactive approach to managing IBS by avoiding symptom triggers rather than treating inflammation after symptoms arise. Many existing IBS dietary interventions, such as the low-FODMAP diet, can be restrictive, difficult to follow, and costly. In contrast, the inFoods ® IBS test enables patients to eliminate only a select number of trigger foods (2 to 4 foods on average) rather than broadly restricting their diet.

“Our diets are complex and identifying dietary triggers can be difficult. This IBS-specific IgG test can help patients who suffer from IBS identify specific dietary triggers,” said Anthony Lembo, M.D., vice chair of Research at Cleveland Clinic’s Digestive Disease Institute.

Advancing Toward Precision Therapy in IBS Treatment

The positive results observed in IBS-M patients are particularly significant, as no FDA-approved medications currently exist for treating this IBS subtype. The study underscores the potential for a precision nutrition approach, allowing healthcare providers to tailor dietary recommendations to each patient’s unique needs.

William Chey, M.D., chief of Gastroenterology & Hepatology at the University of Michigan and a principal investigator in the study, said: “This IBS-specific, IgG antibody test requires additional validation but could move us one step closer to a ‘precision nutrition’ approach, in which providers can offer personalized dietary recommendations to each patient with IBS.”
