Los tests de sensibilidad alimentaria no son una herramienta útil para el diagnóstico o el tratamiento de la obesidad u otras enfermedades: Declaración de Postura del Grupo de Revisión, Estudio y Posicionamiento de la Asociación Española de Dietistas-Nutricionistas (GREP-AEDN)

In the face of the growing use of weight-losing strategies as an alternative to conventional methods, the Revision, Study and Positioning Group of the Spanish Association of Dieticians-Nutritionists (GREP-AEDN) has decided to analyse these methods and to provide information on the degree of efficacy, reliability and/ or risk involved in their use, specifically of the Food Sensitivity Tests. By means of this document, the GREP-AEDN advises against the use of these tests based on blood tests as diagnostic evidence for treating obesity, as well as for detecting possible allergies and/or food intolerances. This position is based on the fact that neither these tests nor the dietary treatments prescribed following their results have been validated by the scientific community. Furthermore, by revising the positions of the most important clinical societies in the field of allergology and immunology, as well as the scientific studies on the matter mentioned in this document, the GREP-AEDN considers that undergoing the dietary treatment resulting from the results of these tests (mainly characterised by the restriction of food items) not only means a waste of money, but it can entail health hazards.
