This invention describes a system to track nutritional information about food items from their origin to when they are consumed. Each food item would have a unique marker or identifier, either directly on it or as an inherent property, which a reader device could scan. This marker would then allow a consumer to retrieve detailed information about the food's creation, origin, and any changes it underwent. The claims specifically focus on systems where the identifier is physically on or part of the nutritional substance, and either contains or references the nutritional data.
Why it matters: Since 2012, ubiquitous smartphone cameras and NFC capabilities have made reading identifiers much simpler and cheaper for consumers. Cloud computing and distributed ledger technologies have also matured, providing robust and scalable solutions for storing and retrieving the vast amounts of nutritional data envisioned.
