Food classification systems that focus on food formulation distinguishable versioning; strong, and ideally causal, evidence of a putative effect of specific processing steps and formulation components with health-related endpoints; evolution over time in response to scientific advances and changes to the food supply; and consideration of current scientific consensus, validation contexts, and the probative value of research questions and new FF&PC systems. These principles are intended to provide a shared foundation and standardized approach to guide researchers in this area without endorsing or advocating for the creation or use of FF&PC systems. These aspirational principles can be used to identify future research priorities and areas for investment while also providing guidance on cautionary action in the absence of complete data. Adherence to these principles is also intended to limit the continued expenditure of resources critiquing or defending new FF&PC systems. These principles can serve as a foundation to support impactful research on FF&PC systems and, through this, public health policy.
