    Food Balance Sheets (FBS) are one of the most important sources of data on food availability for human consumption. This paper presents a method to improve the information on food consumption patterns of FBS by using national household budget surveys (HBS). In this paper, food commodities are categorized into 16 major food groups. For each food group, the contribution to the overall caloric intake is represented in shares. Item group shares of 64 surveys from 51 low and middle income countries are compared with shares from country-specific FBS. Given the countries represented in the data, the analysis evaluates food consumption of over 3 billion persons worldwide. A model based on a cross-entropy measure of information has been developed in order to reconcile aggregate food consumption patterns suggested by FBS and HBS. The latter model accounts for the fact that data from both data sources are prone to measurement errors. Overall, the results of the reconciliation suggest that aver age consumption of cereals, eggs, fish products, pulses and vegetables are likely to be underestimated in FBS, while fruits, meat, milk and sugar products are likely to be overestimated in FBS. Even though the suggested changes in average food consumption are moderate, the results imply considerable relative changes in the aggregate consumption of single food groups. Furthermore, the results imply that the aggregate consumption of fats is 2% higher than currently assumed. The updated consumption patterns provide valuable information from an agro-industrial perspective. Differences in updated consumption pattern with respect to the original FBS might suggest a re-evaluation of FBS elements of the value chain, starting from production and ending at food losses.

    Compendium of food consumption statistics from household surveys in developing countries
    Volume 2 : Africa,Latin America and Oceania

    This first issue of the publication presents data not only from the recent surveys but also, in a number of cases, from some undertaken as far back as the 1970's in order to provide some perspective of the changes over time. However, because of the many surveys involved, it is divided into two volumes: Volume 1,1 covering the surveys conducted in the developing countries in Asia, and the present Volume 2, covering the surveys conducted in the developing countries of Africa, Latin America and Oceania. Another compendium covering the surveys conducted in developed countries will be issued, probably in 1995, following the computerization of all the available survey data in the FAO Statistics Division's database. Subsequently, a single compendium, updating the information, will be periodically issued.

    Compendium of food consumption statistics from household surveys in developing countries
    Volume 1: Asia
    1993
    Also available in:
    No results found.

    This publication aims at providing information on food consumption levels and patterns obtained from household surveys. As such, it replaces the Review of Food Consumption Surveys, which was last issued in 1988. This first issue of the publication presents data not only from the recent surveys but also, in a number of cases, from some undertaken as far back as the 1970's in order to provide some perspective of the changes over time. However, because of the many surveys involved, it is being issued in two volumes: Volume One, covering the developing countries in Asia, and Volume Two, covering the rest of the developing countries in Africa, Latin America and Oceania. Another compendium covering the developed countries will be issued, probably in 1994, following the computerization of all the available survey in the FAO Statistics Division's data base. Subsequently, a single compendium, updating the information, will be periodically issued.
