Analysis of the Nutritional Value of Diets and Food Choices in Polish Female Ulcerative Colitis Individuals Compared with a Pair-Matched Control Sample.

Ulcerative colitis patients often attribute their symptoms to specific dietary products. Therefore, even though there are no specific dietary recommendations, these patients commonly have dietary restrictions, often with no consultation from their physician or dietitian, as they believe that they may be beneficial for them. The aim of the study was to analyze the nutritional value of diets and food choices in Polish female ulcerative colitis individuals, in comparison with a pair-matched control sample. The study was conducted on a group of 44 Polish female ulcerative colitis individuals being in remission and 44 individuals within a pair-matched control sample, matched by their age and concurrent diseases, excluding those resulting from ulcerative colitis. The analysis of the diet was based on the self-reported data, including 3-day dietary records (to assess the intake of nutrients and food products), as well as the simple open-ended question about food products excluded from their diet. It was stated that Polish female ulcerative colitis individuals were characterized by a lower energy value of diet ( p = 0.0043), accompanied by the higher proportion of total protein ( p = 0.0128) than the pair-matched control sample. As a result of a lower energy value for ulcerative colitis individuals, the intake of numerous nutrients was also lower ( p < 0.05); however, after recalculation per 1000 kcal, ulcerative colitis individuals were characterized by higher total protein ( p = 0.0121), starch ( p = 0.0009), and vitamin B 6 intake ( p = 0.0319), as well as lower alcohol intake ( p = 0.0464). Similarly, as a result of a lower energy value for ulcerative colitis individuals, the intake of numerous foods was also lower ( p < 0.05); however, after recalculation per 1000 kcal, ulcerative colitis individuals were characterized by higher meat ( p = 0.0058) and potatoes intake ( p = 0.0052), as well as lower legumes ( p = 0.0301), chocolate sweets ( p = 0.0165), and alcoholic beverages intake ( p = 0.0062). For chocolate sweets ( p = 0.0134) and alcoholic beverages ( p = 0.0091), ulcerative colitis individuals were characterized by a higher frequency of declaration of dietary exclusion. At the same time, ulcerative colitis individuals were characterized by a lower frequency of meeting the recommended intake for magnesium ( p = 0.0005), iron ( p = 0.0189), vitamin E ( p = 0.0389), and vitamin B 1 ( p = 0.0032). It was concluded that even in remission, there is a risk of inadequate consumption, not meeting the recommended intake, and nutritional deficiencies in the population of female ulcerative colitis patients.
