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.

A 2020 study in the British Journal of Nutrition found that drinking unpasteurised milk increases levels of Lactobacillus in the gut—beneficial bacteria that support digestion and immune health. Two studies in The Journal of Allergy and Clinical Immunology (2011 & 2015) linked raw milk to a significantly reduced risk of asthma, allergies, and respiratory infections in children.
