1. A system using a food recognition device in communication with a database via a network, that determines a nutritional value of a food item, comprising:

  • a food container with one or more partitions, the one or more partitions being defined by a boundary outlined by a divider and a peripheral wall formed by the food container, wherein the food container receives the food item, the food container being characterized by a predetermined structural properties;

    a weight sensor being placed within the food container, positioned to measure a weight of the food item being received by each of the one or more partitions;

    an image capturing device capturing an image of the food container; and

    the food recognition device, with a processor and a memory, in communication with the weight sensor and the image capturing device, configured to;

    obtain the image of the food container from the image capturing device;

    correct orientation of the image by aligning the boundary in the image with the boundary in a reference food container image stored in the database;

    segment the image based on the boundary to isolate each of the one or more partitions; and

    identify a type of the food item by comparing each segmented image to a reference segmented food image stored in the database.
