Talk: Saana Jukola (Bielefeld)
Standards of evidence and nutrition advice
It has become common to criticize dietary recommendations for not being based on randomized controlled trials. In this talk, I will show that this tendency to evaluate nutrition advice on the basis of evidentiary standards originating from evidence-based medicine is problematic. Due to practical, ethical and methodological and reasons, it is difficult to conduct rigorous randomized controlled trials for acquiring evidence that is relevant for achieving the goals of population-level nutrition recommendations. Given the non-epistemic goals of the dietary recommendations, criteria of acceptable evidence should be adapted to the goals of the practice and the practical, ethical, and methodological constraints of the situation.
