چکیده انگلیسی
Total Diet Study (TDS) has been adopted worldwide and is based on the evaluation of food samples representing a Market Basket, which shows dietary habits of a large-scale population. This TDS presents results of the element concentrations, daily dietary intakes and contributions to the total daily intake of essential elements, Na, K, Ca, Fe, Zn and Cr in 30 food groups of a Market Basket of São Paulo State, Brazil. The methodology for the first Brazilian TDS for the São Paulo State population and its respective Market Basket was developed. Food consumption data and information were obtained from the National Household Food Budget Survey, Pesquisa de Orçamentos Familiares (POF) 2002-2003 conducted by the Brazilian Institute for Geography and Statistics, which includes 5440 foods. The selection criteria to carry out the Market Basket were the foods consumed at more than 2 g/day/person, which represented 72% of the total weight of the foods for this population. Element concentrations were determined by instrumental neutron activation analysis and ranged in mg kgâ1 as follows: Na: 1.5-256,185; K: 0.51-532; Ca: 22-1827; Fe: 0.08-49; Zn: 0.030-98; and in μg kgâ1 Cr: 2.6-799. The dietary intakes contributed by the Market Basket were: 1928 mg/dayâ1 Na; 861 mg/dayâ1 K; 275 mg/dayâ1 Ca; 5.70 mg/dayâ1 Fe; 4.25 mg/dayâ1 Zn and 20.7 μg/dayâ1 Cr. The observed low levels are probably due to the fact that Market Basket represented 72% of the weight of the household consumed foods. The highest contributions to the total intake of the essential elements were: salts, 78.9% of Na; breads, 36.9% of Fe and 46.4% of Cr; cereals, 18.7% of Zn; and milk/cream, 58.7% of Ca and 23.6% of K.
