It is an issue of great significance from health, social, economic, and moral perspectives (Jones et al., 2013). Global food insecurity is rising rapidly, and current predictions indicate that the situation will worsen in the coming years (Delgado et al., 2023). In South Africa, food and nutritional security remain pressing issues that have yet to be resolved. Hunger and malnutrition create a cycle that hampers the development of the South African population, ultimately preventing the realisation of its full potential. We live in a society plagued by malnutrition and food insecurity, characterised by the triple burden of malnutrition. This includes the coexistence of both overnutrition and undernutrition, as well as deficiencies in micronutrients, which exacerbate the other two issues. This paradox arises from shared root causes and the consequences of poverty and food insecurity (Jones et al., 2013; Ghattas, 2014; Stats SA, 2019c). In essence, poverty and food insecurity are perpetuating each other. A serious hurdle in developing policies related to food security in South Africa is the lack of comprehensive national data on the food intake patterns of adult South Africans. You cannot change what you cannot measure, and without nationally representative data on food intake patterns to perform dietary assessment, Government and relevant stakeholders are unable to create, implement, and measure the success of targeted interventions. This study aims to explore the complexities of food security in South Africa and improve the understanding of its dynamics by enhancing data collection and employing innovative methodologies. Current data on food security is often outdated, incomplete, or fragmented, highlighting the need for more comprehensive information. To effectively address food security challenges in South Africa, it is crucial to develop and implement new methodologies that consider the complex interplay of factors such as socio-economic status and food systems. Additionally, these methodologies should incorporate qualitative data and community perspectives. The main contribution of this study is to provide a proof of concept for developing and testing an alternative methodology for assessing food intake. This research will adopt a multi-disciplinary approach that is both time- and cost-effective in evaluating dietary patterns. The study aims to support data collection by enhancing and refining food intake methodologies, contributing to the limited information available on consumption patterns in the South African context. Furthermore, the analysis resulting from this research is expected to advance existing theories related to food and nutritional security in South Africa, as well as improve food intake methodologies on a broader scale. AFRIKAANSE OPSOMMING: Voedselsekerheid is 'n globale krisis en een van die grootste uitdagings van die 21ste eeu (Pereira & Drimie, 2016). Dit is 'n kwessie van groot merkwaardigheid vanuit gesondheid-, sosiale-, ekonomiese- en morele perspektiewe (Jones et al., 2013). Globale voedselonsekerheid neem vinnig toe, en huidige voorspellings dui aan dat die situasie in die komende jare sal vererger (Delgado et al., 2023). In Suid-Afrika bly voedsel- en voedingsekerheid dringende kwessies wat nog nie opgelos is nie. Hongersnood en wanvoeding skep 'n siklus wat die ontwikkeling van die Suid-Afrikaanse bevolking belemmer, wat uiteindelik die verwesenliking van sy volle potensiaal voorkom. Ons leef in 'n samelewing wat geteister word deur wanvoeding en voedselonsekerheid, gekenmerk deur die drievoudige las van wanvoeding. Dit sluit die saamlewing van sowel oor- en ondervoeding in, sowel as tekorte in mikrovoedingstowwe, wat die ander twee probleme vererger. Hierdie paradoks is beide ‘n oorsaak en nagevolg van armoede en voedselonsekerheid (Jones et al., 2013; Ghattas, 2014; Stats SA, 2019c). In wese bevorder armoede en voedselonsekerheid mekaar. 'n Ernstige struikelblok in die ontwikkeling van beleide rakende voedselonsekerheid in Suid-Afrika is die gebrek aan omvattende nasionale data oor die voedselinnamepatrone van volwasse Suid-Afrikaners. Mens kan nie verander wat jy nie kan meet nie, en sonder nasionaal verteenwoordige data oor voedselinnamepatrone om dieetbeoordeling uit te voer nie, kan die regering en betrokke belanghebbendes nie doelgerigte intervensies skep, implementeer en die sukses daarvan meet nie. Hierdie studie het ten doel om die kompleksiteite van voedselonsekerheid in Suid-Afrika te ondersoek en die begrip van die dinamika daarvan te verbeter deur dataversameling te verbeter en innoverende metodologiee in te stel. Huidige data oor voedselonsekerheid is dikwels verouderd, onvolledig of gefragmenteer, wat die behoefte aan meer omvattende inligting beklemtoon. Om die uitdagings van voedselonsekerheid in Suid-Afrika effektief aan te spreek, is dit van kardinale belang om nuwe metodologiee te ontwikkel en te implementeer wat die komplekse interaksie van faktore soos sosio-ekonomiese status en voedselstelsels in ag neem. Boonop moet hierdie metodologiee kwalitatiewe data en gemeenskaps perspektiewe inkorporeer. Die hoofbydrae van hierdie studie is om 'n bewys van konseptualisering te lewer vir die ontwikkeling en toetsing van 'n alternatiewe metodologie om voedselinname te assesseer. Hierdie navorsing sal 'n multidissiplinere benadering volg wat beide tyd- en koste-effektief is om dieetpatrone te evalueer. Die studie het ten doel om dataversameling te ondersteun deur die metodologiee vir voedselinname te verbeter en te verfyn, wat sal bydra tot die beperkte inligting wat beskikbaar is oor verbruikspatrone in die Suid-Afrikaanse konteks. Verder word verwag dat die analise wat uit hierdie navorsing voortspruit, bestaande teoriee rakende voedsel- en voedingsekerheid in Suid-Afrika sal bevorder, sowel as metodologiee vir voedselinname op 'n breer skaal te verbeter.
