A vending system restricts, limits and/or controls access and/or to various products, and tracks purchases, use or consumption of those products by an individual, group, class or classification, and implements continued decisions regarding future access within the context of a hierarchy of policy enforcement or guideline recommendations. The individual or group is associated with a unique identification, captured by an input device, such that product selection availability is based upon identity, product type, quantity limits, serving recommendations and nutritional guidelines, user preferences, governance and access restrictions. Subsequent tracking of the dispensing of products, permits the system to compare consumption and make future decisions regarding access to products.
