对巴西水果和蔬菜消费的三个层面的膳食数据进行了分析和比较。有关国家供应的数据来自粮农组织编制的食品平衡表；家庭可用性信息来自巴西国家家庭预算调查（HBS）；实际摄入量信息来自一项代表圣保罗市成年人口的大型个人膳食摄入量调查。所有信息来源均在 2002 年至 2003 年期间收集。我们的分析中使用了代表圣保罗市的 HBS 子集，以提高与实际摄入量数据的比较质量。水果和蔬菜的全国供应量与家庭可获得量的比率为2.6，而全国供应量与实际摄入量的比率为4.0。家庭可获得性与实际摄入量的比较差异比较小，为1.6。虽然使用供应和可获得性数据具有成本较低的优点，但必须考虑到这些来源往往会高估水果和蔬菜的实际摄入量。
Information on fruits and vegetables consumption in Brazil in the three levels of dietary data was analyzed and compared. Data about national supply came from Food Balance Sheets compiled by the FAO; household availability information was obtained from the Brazilian National Household Budget Survey (HBS); and actual intake information came from a large individual dietary intake survey that was representative of the adult population of Sao Paulo city. All sources of information were collected between 2002 and 2003. A subset of the HBS, representative of Sao Paulo city, was used in our analysis in order to improve the quality of the comparison with actual intake data. The ratio of national supply to household availability of fruits and vegetables was 2.6 while the ratio of national supply to actual intake was 4.0. The discrepancy ratio in the comparison between household availability and actual intake was smaller, 1.6. While the use of supply and availability data has advantages, as lower cost, must be taken into account that these sources tend to overestimate actual intake of fruits and vegetables.
