Foodborne challenges, including, the ingestion of pathogens, toxins, and allergens, trigger a series of physiological and endocrine responses that are essential for maintaining homeostasis and protecting the body from harm. The endocrine system plays a key role in mediating these responses through the activation of various hormonal pathways. Upon exposure to foodborne pathogens, hormones such as cortisol, insulin, ghrelin, leptin, and glucagon are involved in modulating immune function, metabolic processes, and gastrointestinal motility. Additionally, the hypothalamic-pituitary-adrenal (HPA) and the gut-brain axes play crucial role in coordinating systemic responses to stress and infection. These endocrine alterations help manage inflammation, enhance immune defences, and regulate energy balance. However, prolonged or exaggerated responses to foodborne challenges may lead to metabolic dysregulation, immune dysfunction, and an increased susceptibility to chronic diseases. This chapter explores the complex interplay between foodborne challenges and endocrine responses, emphasizing the importance of these processes in health and disease.
