title: [Comparison of analized and calculated energy, fat, protein, dietary fiber, iron and zinc values in diets from different socioeconomic levels in northern México].
abstract: Traditional methods of dietary assessment such as measuring nutrient intake with 24 h dietary recalls, food frequency questionnaires and multiple-day food records, depend upon the use of data base systems to estimate nutrient data. Certain problems exist with the data from these sources. For Mexico, the most serious one is that in many of the systems certain nutrient data is lacking and many of the traditional foods are not included. The objective of this study was to analyze regional diets for protein, fat, dietary fiber, iron and zinc and compare these values with those estimated from two different data bases, ALIM 10.000 which includes regional dishes and foods and Nutritionist III, which includes data from Handbook 8. Energy values were calculated using reported values. The results showed that the bases produced comparable values to those analyzed for energy, protein, fat, however for micronutrients the data bases generally overestimate the analyzed values. The results of this study emphasize the need to update data bases with new product information, re-examine certain values on basis of newer methods, and to include data for ethnic foods.
