Reducing sugar intake has become a focus of many national and international public health policies due to the association between added sugar (AS) intake and the risk of obesity and diabetes. The World Health Organization (WHO) strongly recommended in 2015 that ASs be reduced to 10% of total dietary energy (TE) and 5% of TE for health benefits. This study aims to determine the level of consumer awareness of AS and to demonstrate their ability to classify AS correctly, their awareness of the WHO guidelines regarding the amount of sugar consumed per day, the extent to which the updated food labelling can help manage sugar intake and facilitate healthy food choices, and to examine the influence of gender, age, education level and city on consumer awareness of AS. The study was conducted using an electronic questionnaire administered via social networking sites, gathering responses from 1607 consumers across different cities. The questionnaire covered four main axes: personal information, the importance and use of the Nutrition Facts Label, awareness of the WHO's recommendation, and the ability to correctly classify different types of sugars. Statistical analysis was performed using the Chi-Square test and analysis of variance (ANOVA) at a 5% significance level using the SPSS program. The results of the questionnaire in the sugar classification axis showed that only 23.31% of consumers were able to correctly classify 8 ASs from a list of 10 different sugars, and that the educational level has no effect on consumers' awareness of the classification of ASs. The results of the WHO awareness axis showed that 48.81% of consumers were not aware of the WHO guidelines for reducing ASs, while 26.18% of consumers were not aware of the existence of the WHO in the first place. The results of the nutrition facts label use axis showed that 22.42% of consumers consider the nutrition facts label a reliable source, while 28.15% consider the food label an unreliable source. We conclude that the level of consumer awareness of ASs in Libya is very low, even among consumers with a university education and a higher diploma. Accordingly, awareness and education campaigns should be intensified and focused on through various media outlets about the importance of ASs to preserve the health and safety of consumers in Libya............................
