Introduction:
Nutritional habits are significant not only in maintaining good health, but also in preventing many diseases. Proper nutrition also helps to maintain the right body weight. Due to growing consumer interest in these issues, a new food market sector, namely light foods, has emerged. The aim of the study was to assess the consumption frequency of light foods and drinks and to analyse the relationship between the consumption frequency and age, education and body weight of the respondents.

Material and methods:
The study involved 203 adults who declared the consumption of light foods and drinks. The frequency of consuming light foods and drinks was assessed on the basis of the author's own survey questionnaire.

Results:
The largest proportion of respondents choose light dairy products several times a week (23.2%) or occasionally (40.4% of respondents). Fat products of a light type and light sweets were consumed occasionally by 34.5% and 30% of respondents respectively. Light drinks were in most cases consumed several times a month (20.7%) and occasionally (40.4%).

Conclusions:
The consumption of fast foods is rare among the respondents. There was a weak or low correlation between the frequency of light food consumption and age, education and body weight of the respondents. It seems necessary to provide nutrition education from an early age, especially among children and adolescents, and to continue it with adults.
