A dietetic scale and method for calculating and tracking nutritional content information. The scale includes a bar code reader for identifying a food product from its package, with food content data per unit weight of the product being retrieved from a database. The database is a compilation of standardized nutrition facts promulgated by the FDA or other authority for the food products, with the bar code being correlated with the food products by means of their individual UPC numbers.
