RESUMEN
In recent decades in high industrialised countries the occupational risks and energy costs of labour have decreased while the subjective nutritional and metabolic risk of workers has increased because they often follow an incorrect lifestyle. This article addresses the multidisciplinary assessment and management of these risks in order to define a Nutrient Hazard Analysis and Critical Control Point at Work (NACCPW), specifically dedicated to proper nutrition, which workers must take over before or during the work schedule. It describes the various steps that the professionals concerned will need to develop to define the work-related and subjective metabolic and nutritional critical points and their corrective actions. NACCPW allows to balance work-related metabolic risk with subjective nutritional risk of workers and gives indications to reduce both. The further improvement in working conditions and lifestyle, with a focus on the nutrition of workers, will help to prevent cardio-vascular, metabolic and cancer diseases still very common in Western countries. The effectiveness of NACCPW is ensured by the possibility of including it in periodic health surveillance, which is required by law, for the entire working life.
