Taste preference for sweetness in urban and rural populations in Iraq.

The consumption of sweetened foods is influenced by a variety of biological, psychological, sociological, and environmental factors. On an individual level, taste preference for sweetness has been shown to have an influence on food consumption, although this may be affected by social and environmental factors. The aim of this study was to assess the taste preference for sweetness in urban and rural populations in Iraq. The hypothesis was that sweet preference and the consumption of sugar increase with urbanization. The sample was composed of 4152 individuals who were divided into urban and rural subgroups based on their place of residence. Sweet preference was assessed by means of a tested Sweet Preference Inventory. Results revealed statistically significant differences between urban and rural populations in preference for sweetness and in actual sugar consumption. Individuals from urban locations showed a much higher preference for sweetness than their rural counterparts and consumed more sugar. Within the urban population, those individuals who had lived in the city longer and who were from families with lower educational qualifications preferred the highest levels of sugar. The findings support the hypothesis that urbanization influences sweet preference and sugar consumption.
