### Core Dietary Determinants of Allergy Prevention and Management Within Sustainable Eating Models
These elements interact with key immune pathways such as mast cell degranulation, SCFA-mediated Treg induction, epithelial reinforcement, and modulation of antigenic protein structures. The EAT-Lancet dietary model, with its emphasis on minimally processed foods and sustainable culinary traditions, inherently promotes these protective elements by favoring foods that are nutrient-dense, fermentable, and associated with non-putrefractive gut microbial profiles. While further clinical studies are warranted to confirm these effects
