Salt literacy among youth: the gap between theoretical knowledge and dietary habits

Abstract

The theses address salt literacy among young people as an important component of healthy dietary behaviour formation. Based on an anonymous online survey of respondents aged 16–21 years, the study analyses the level of awareness regarding recommended salt intake, the risks of excessive sodium consumption, attitudes toward iodised salt, and everyday behavioural practices. It was found that young people’s knowledge about safe salt consumption is mostly superficial, while their actual dietary habits often do not correspond to the principles of preventing iodine deficiency and cardiovascular disorders. The study demonstrates a low frequency of iodised salt use, insufficient control of hidden sodium in foods, and a significant influence of non-specialised digital information sources. The need to strengthen educational and preventive measures aimed at improving salt literacy among youth and fostering a culture of healthy eating is substantiated.
