Introduction:
Prebiotics are substances that support the development and activity of the gut microbiota by stimulating the growth and function of the bacteria inhabiting the large intestine. These compounds are not digested in the human gastrointestinal tract. They include, among others, starches and dietary fiber.

Material and methods:
The research material consisted of a group of 140 individuals: 99 women and 41 men aged between 30 and 50 years. The research method used in the study was a diagnostic survey, with a proprietary questionnaire being the research tool.

Results:
The correct definition of the term “prebiotic” was selected by 57.1% of the respondents, while 25% confused it with probiotics. The terms “probiotic” and “prebiotic” were considered synonymous by 20% of respondents, whereas 12.1% were unable to answer the question. More than half of the respondents (57.6%) knew that probiotics can be combined with prebiotics, but only 48.6% could identify a range of products that contain them. According to 65% of respondents, prebiotics undergo fermentation in the digestive tract, which is the correct answer, whereas 35% provided an incorrect response.

Conclusions:
Some respondents were aware of the positive effects of prebiotics on gut health. However, specific health benefits and prebiotic-rich products remain unclear to many. The results indicate a need for further public education, including a detailed explanation of the differences between prebiotics and probiotics and their role in human nutrition.
