Abstract

Plant sterols are compounds with multiple biological functions, mainly cholesterol-reducing. There are no comprehensive databases on plant sterols, which makes it difficult to estimate their intake in the Polish population. In this study we used international food databases, supplemented by scientific data from the literature, to create a database on plant sterols in the food consumed in Poland to assess the size and sources of dietary plant sterols in the adult population of Poland. The literature search was conducted using PubMed, Web of Science, Scopus, and Google Scholar to identify possible sources of published food composition data for plant sterols. The study group consisted of 5690 participants of the WOBASZ II survey. We identified 361 dietary sources of plant sterols based on the consumption of foods and dishes reported by participants. Cereals and fats provided 61% of the total plant sterols, and together with vegetables and fruits, this totaled 80%. Total plant sterol intake for the Polish population was 282.97 mg/day, and divided by men and women was 320.77 and 252.19 mg/day, respectively. Canola oil provided the most plant sterols at 16.92%, followed by white bread at 16.65% and soft margarine at 8.33%. This study found that the database of plant sterols facilitates the calculation of plant sterols in the typical Polish diet, and the results are comparable to those of other studies, despite different methodologies of nutritional assessment and slightly different databases. The main sources of dietary plant sterols did not differ from the data for other populations. This study confirmed the observations of other research that women's diets may have a higher plant sterol density compared to men.
