The lack of food intake data and the consequences thereof
AbstractGenerally, South African researchers working in the fields of nutrition and dietetics collect food intake data as a first step towards determining
the nutritional status of various populations. However, on publication, the majority of the results obtained from these studies are expressed
in terms of nutrient intake, whereas food intake data are either not included, or are presented in non-uniform formats. Subsequently, other
researchers who wish to determine what foods South Africans are eating are not able to access food intake data from existing studies. For
example, if the Food-Based Dietary Guidelines (FBDG), which are expressly based on food, and not nutrient intakes, are to be revised regularly
as stipulated by the World Health Organization (WHO), very little additional food intake data from the decade following publication of the first FBDG in 2001 would be available for adult South Africans. It is probable that the consumption of certain foods may have increased because of urbanisation and Westernisation of large sectors of the population. Conversely, economic factors, including the present recession, household food insecurity and poor food choices, may have reduced the intake of nutrient-dense foods in the past decade. The present review describes the disparity in reporting of food intake data, and deficiencies in making data that are available in electronic storage systems accessible to
researchers working in the fields of public health nutrition, food production and utilisation, community nutrition and education. The creation of
a working committee to make food intake data more accessible is proposed.
