[Food allergy and environmental contamination].

The interaction between genetic potential and the environment, especially increased urbanization and inadequate waste management, contributes to the manifestation of allergic diseases. Pediatric patients are the most vulnerable, due to the immaturity of the respiratory and immune systems. Prenatal and postnatal exposure to air pollutants, both indoors and outdoors, accelerates or aggravates morbidity and mortality from allergic diseases. The "exposome," which encompasses all environmental exposures throughout life, influences health. Biological and chemical attacks alter the epithelial barrier, triggering inflammatory responses and favoring allergic diseases, such as food allergies. The uncontrolled use of toxic fuels, particulate matter, detergents and other factors contribute to the continuous deterioration of the intestinal epithelial barrier, increasing the risk of allergic diseases. It is important to take urgent action to address these issues and protect the health of the planet.
