Abstract:
The objective of this study was to estimate the household availability of fibers in Brazil and to identify the dietary sources of this nutrient. Data from the 2008-2009 Household Budget Survey were used to estimate national household availability and density of fibers and also according to stratifications defined by income level, five regions and area (rural or urban). The contribution of the different food groups, classified by the nature, extent and purpose of processing, to total fibers available in Brazilian households was also determined. The mean density of per capita fibers was 7.6 g/1000 kcal. Higher availability and density of fibers was observed in households situated in rural areas and among low-income families. The main dietary sources of fiber were beans, bread, rice, fruit, vegetables and manioc flour. Fiber intake was found to be insufficient. Therefore, actions promoting a healthy diet are needed to improve the dietary quality of the Brazilian population.
