Food Allergies Can Alter Your Brain—But Probiotics Might Fix It.

A 2025 study from Shanghai Jiao Tong University showed that food allergies don’t just cause rashes or stomachaches—they can lead to anxiety, depression, attention issues, and social withdrawal. In this mouse model, food allergy triggered brain inflammation, impaired behavior, and disrupted the gut microbiota.

When scientists gave the mice a mix of Bifidobacterium and Lactobacillus strains, these problems improved. The probiotics reduced allergy symptoms, restored gut bacteria, rebalanced amino acid metabolism, and even calmed inflammation in the brain. The result? Mice acted more relaxed, focused, and social—because their gut and brain were both healthier.

If you’re struggling with food sensitivities and mood issues, consider using multi-strain probiotics.
