Bifidobacteria are a group of probiotic bacteria that have been studied for their potential role in supporting or treating food allergies. The scientific basis for their use is rooted in the understanding that the gut microbiota plays a crucial role in the development and regulation of the immune system. Several studies, particularly in infants and children, have observed that individuals with food allergies often have altered gut microbiota, including reduced levels of Bifidobacteria. Animal studies and some human clinical trials suggest that supplementation with specific strains of Bifidobacteria may help modulate immune responses, enhance the gut barrier function, and potentially reduce allergic inflammation.

However, the clinical evidence remains limited and variable. While some small-scale randomized controlled trials (RCTs) have reported improvements in symptoms or biomarkers of food allergy (such as cow's milk allergy) with Bifidobacteria supplementation, other studies have found little to no effect. Most research has focused on prevention (e.g., in infants at high risk for allergies) rather than treatment of established food allergies. Systematic reviews and meta-analyses generally conclude that, although probiotics like Bifidobacteria are promising, the evidence is insufficient to recommend them as a standard therapy for food allergies at this time. More large, well-designed trials are needed to confirm efficacy, optimal strains, and dosing.
