Hunger and appetite have been intertwined throughout human history, where eating serves not only a nutritional function but also a social and emotional one. From birth, the body mediates our relationship with the world, linking eating disorders to body image. Neuroscience, phenomenology, and anthropology agree that mind, body, and environment interact in an individual’s adaptation (Alvarez J, Esteban R, Sauvagnat F, Fundamentos de psicopatología psicoanalítica. Editorial Síntesis, Madrid, 2002). Anorexia nervosa (AN) and bulimia nervosa (BN), described in the nineteenth and twentieth centuries, respectively, disrupt food intake and body perception, affecting both physical and psychosocial health (Bruch, Psychosom Med 24:187–194, 1962). Other disorders, such as pica, rumination disorder, and sitiophobia, are less common, whereas binge-eating disorder is rising to epidemic levels, influenced by body image ideals and the growing popularity of dieting in Western societies (Sideli and Micali, Eur Eat Disord Rev 29:826–841, 2021). Eating goes beyond mere nutrition; it is a social and symbolic act that reflects cultural, emotional, and even religious aspects. While hunger is an urgent biological need, appetite is shaped by sociocultural factors and personal preferences (Contreras J., Antropología de la alimentación. Ed Eudema, Madrid, 1993). According to Scheler and Strunz, sensory feelings such as hunger or thirst are localized and temporary, whereas vital feelings affect the entire organism, generating a broader sense of well-being or discomfort (Scheler and Strunz, Phenomenol Psychol. 3:45–67, 1928). The relationship with food begins at birth through breastfeeding, which not only provides nourishment but also strengthens the emotional bond between mother and child (Bowlby J., Attachment and loss. Basic Books, New York, 1969). Throughout history, food consumption has been influenced by beliefs and customs, from dietary taboos to religious rituals such as the Christian Eucharist or the Hebrew concept of incorporating the divine through food (Douglas M. Purity and danger. London: Routledge, 1966). In today’s society, eating habits fluctuate between the industrialization of processed foods and the rise of trends like healthy eating, fasting, and the search for “real food.” (Patel R, Obesos y famélicos. Barcelona, Ed Los libros del lince, 2008). Eating—or even refusing to eat—also holds political and social significance, as exemplified by the hunger strikes of early suffragists in their fight for rights (Brumberg JJ, Fasting girls. Harvard University Press, The emergence of anorexia nervosa as a modern disease. Cambridge, 1988). Thus, food is not merely a biological act but a reflection of our cultural and personal identity.
