I have read with great interest the recently published original article ‘Diagnosing clinical malnutrition: Perspectives from the past and implications for the future’ by Levi M. Teigen et al. [ 1 ]. By giving key historical elements, the authors aim to contribute to move forward on an international accepted definition of malnutrition. The authors propose a shift of paradigm by putting, in the core of the research efforts, the emphasis on the identification of nutrition-related variables capable of predicting outcomes and responsiveness to nutrition intervention. In contrast to the authors, I propose a different approach based on a philosophical study of the emergent knowledge through the historical review (i.e. “historical epistemology”) with a view to answer one fundamental question: is malnutrition a disease? In other words, what is the definition of the malnutrition's nature?
