Abstract
A method is provided for assigning a relative score number to foods. Assignment of a relative score number to foods allows consumers to select foods that will provide a desirable diet. Equations are provided which are effective to yield a predicted raw score based on measured characteristics. The predicted raw score statistically correlates to a raw score that would be determined by an actual panel. The predicted raw scores are further processed to provide a relative score number that can be easily tracked by a consumer.
