Introduction:
Sucrose, also referred to as “refined sugar” by consumers, is a substance that is directly associated with sweet taste. The dietary market, however, offers many more sources of this flavor. The aim of this study was to determine whether there are relations between the level of sweeteners related knowledge and factors such as place of residence, education, sex, age or body mass index (BMI). In addition, the overall sweeteners related knowledge was examined, and it was determined which sweetener is best recognized.

Material and methods:
The study was conducted in five “Dialab” laboratories in the Lower Silesia region from April to May 2017. The sample selection was random. 132 people participated in the study.

Results:
In the studied population only 15 patients showed that they suffered from diet-related diseases. Approximately 87.9% of the patients claimed that they eat healthy. Honey (73%), xylitol (52%) and stevia (48%) were found in the group of the most well-known sweeteners. A significant correlation was also found between BMI and the level of knowledge about sugar substitutes.

Conclusions:
The place of residence, education, age and sex have no influence on the nutritional awareness of respondents. A factor that plays a role in this regard is a high BMI. An attempt to determine whether diet-related illnesses have a significant impact on increasing the knowledge about sweeteners requires follow-up studies, as the conclusions of observations to date are not sufficient to support this claim. The level of knowledge about the sweeteners of the test subjects is classified as acceptable.
