The invention relates to the field of health management and intelligent terminals, and discloses a
nutrition management method and
system, a terminal and a storage medium, and the
nutrition management method comprises the following steps: an integrated voice recognition module is used for capturing a voice instruction of a user and analyzing a user demand; deploying an
augmented reality engine, generating a virtual food model according to a user demand, and displaying a visual effect of the food combination in real time; and establishing a personalized diet
database, comprehensively analyzing
health data and living habits of the user, and generating a dynamic diet plan. According to the invention, a multi-
modal fusion voice recognition and
augmented reality scheme is adopted, and a personalized diet
database and a sensor network are combined, so that real-time
diet management and plan adjustment are realized. The diet health influence is dynamically displayed through an
augmented reality simulation tool, flexible intervention is provided through an intelligent reminding
system, and the problems that in the prior art, the feedback mode is single, and behavior guidance is not in place are solved.
