Abstract: Systems and methods for providing nutritional recommendations to a registered customer of a business make use of a central computer server and a database including nutritional scores associated with products offered by the business. The central computer server receives a list of products purchased by the customer from the business, and processes that list to assign a nutritional score from the database to each of the products purchased by the customer. The nutritional score of each of the products purchased by the customer is then compared with a nutritional score of one or more product alternatives such that, based on that comparison, a recommended product alternative is selected having a nutritional score higher than a corresponding one of the products purchased by the registered customer. The recommended product alternative is then transmitted to the customer via a software application running on a mobile device of the registered customer.
