In 2025, health experts reviewed animal and lab studies on trimethylbenzoyl diphenylphosphine oxide (TPO), a chemical in gel nail polishes banned in the EU but still used in the US. They examined TPO’s effects on reproduction, cancer risk, and skin reactions, using data from rat, rabbit, and human cell tests.

In 2025, Carina Venter and a team from the University of Colorado Anschutz Medical Campus studied 84 healthy infants. They randomly gave one group freeze-dried blueberry powder from 5-6 months old, mixed into food, while the control group got no blueberries. They tracked allergies like eczema or food reactions, immune markers in blood, and gut bacteria via stool samples over 6 months.

A 2025 report from EAACI and EMJ highlights that kids with atopic (allergic) asthma are significantly more likely to have sensory-processing issues like trouble tuning out noise or handling light, or even touch.

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.
