The article approaches some thoughts about the notion of healthy eating produced in the social imaginary in contemporary Western society oriented for health as a search for cure or disease prevention. Theoretical basis of Sciences and Humanities provided better conditions to understand feeding as an interstitial thematic articulation between the biological and psychosocial. First, we emphasize healthy eating derived from modern scientific rationality and general normativity. Then we problematize the discursivity of health promotion from the Foucault's concept of biopower. We do not deny the value of the epidemiological evidence about the direct relationship between food and illness and we recognize that knowing is better than ignoring when action is needed. However, we believe that we should not normalize feeding and look at scientific information as something absolute, because we believe that for the (re)establishment of health more than prescribing nutrients and food is required. The economic and the political interests of hegemonic sectors related to the biomedical dimension does not allow much space for the discussion of psychological and / or social matters. So, new conceptual tools and theoretical foundations that are not in the "true" of the biological discourse are needed in propositions on healthy eating
