Is provision of substantial dietary interventions for brain health ethical?

Abstract

We argue that the provision of substantial dietary modifications to individuals who wish to maximize their brain health is ethically permitted, despite evidence for such an intervention being not yet fully conclusive. However, we argue that for a burdensome therapy with weak evidence and potential harms, balanced communication, informed consent and follow-up are necessary components of the ethical provision of such lifestyle changes. Moreover, health should be discussed as a value with individuals alongside non-health priorities to achieve balance and avoid brain healthism.
