The seven-step process of precision public health nutrition has safety, ethics, and impact at its core. Step 1: nutritional challenges and target populations are identified. Step 2: current methods and solutions are assessed. Step 3: precise approaches to collect and analyze detailed data are performed. Step 4: tailored nutritional solutions are identified and developed to mitigate the nutritional challenge. Step 5: subgroups in need are targeted with precise solutions. Step 6: the intervention data are collected and analyzed to develop well-informed nutritional recommendations and solutions (step 7), or the process cycles back to step 1 to repeat and ensure precise, effective approaches are implemented to address the nutritional challenges of target groups.
