Dietary analysis with programmable calculator: a simplified method.

The use and applications of programmable calculator in dietary analysis are presented. Results which approximate those of large computers can be obtained with considerably less time, money, and data manipulation. Program flexibility allows operators to determine the number of foods and nutrients to be analyzed. Input, data checking, and results of total nutrient consumption are achieved within minutes. The dietary analysis described in this article is well suited for small hospitals and clinics, for teaching purposes and dietary surveys and for use by non-nutritionists who have a one-time or regular need to incorporate dietary information into their work.
