摘要

The major energy foods in Sonora, Mexico, are beans and corn and flour tortillas. The daily intake of beans was 329 g, corn tortillas, 253 g, and flour tortillas, 105 g. The chemical composition of the diet for low-income adults, 25 years or older, was analyzed according to AOAC (1990) methods for protein, fat, dietary fiber, phytates, Fe, Zn, Se, and Ca. The results of this study showed intakes of 92.98 g/day of fat, 104.33 g/day of protein, 49.24 g/day of dietary fiber, 2088 mg/day of phytates, 19.50 mg/day of Fe, 19.50 mg/day of Zn, 1164 mg/day of Ca, and 171.68 mu g/day of Se for a diet of 2667 kcal. All of these levels exceed the U.S. RDAs and the recommendations for Mexico (NAS, 1989; INN, 1977). Comparing the analyzed values with calculated values from databases, the values for the macronutrients agreed more closely than did the values for micronutrients; however, databases that include regional foods must be used. Minerals and phytates, with the exception of Ca, are insoluble, which could indicate the presence of unavailable phytate-mineral complexes.
