Objective: Research data demonstrating nutritional habits of functional dyspepsia (FD) patients are very limited. This is the first study to evaluate nutritional habits in FD subgroups according to Rome III criteria. Our aim was to evaluate nutritional habits of FD patients and determine the food items that may provoke a dyspepsia symptom. Methods: A total of 168 adults with FD and 135 healthy control subjects participated in the study. FD subjects were divided into epigastric pain syndrome (EP-FD), postprandial distress syndrome (PS-FD), mixed (MX-FD) subgroups according to Rome Criteria III. Subjects completed a questionnaire that included a short-form food frequency questionnaire. Furthermore, subjects were asked to list the food items that were causing a dyspepsia symptom. Results: Functional dyspepsia subjects had a slightly higher BMI (26.1 ± 4.97 kg/m2) than control subjects (24.6 ± 4.08 kg/m2). The most common symptom triggering foods among all the FD groups were fried and fatty foods (27.1%), hot spices (26.4%), and carbonated drinks (21.8%). In FD subgroups, carbonated drinks were more likely to cause a symptom in PS-FD group (37.3%) than MX-FD (25.7%) and EP-FD (22.1%) groups. There was no difference in frequency of main meals and snacks among any of the groups. Conclusion: Fatty and spicy foods and carbonated drinks were the most common symptom triggering food items in FD group. In subgroups, carbonated drinks and legumes were more likely to cause a symptom in PS-FD. Removing these food items during the course of treatment might help alleviate the symptoms.

The objective of this study was to evaluate the nutrient profile of labelled foods and also understand the application of two international nutrient profiling models of labelled foods and beverages. WXYfm and NRF 9.3 nutrient profiling models were used to evaluate 3,171 labelled foods and beverages of 38 food categories and 500 different brands. According to the WXYfm model, pasta, grains and legumes and frozen foods had the best scores whereas oils had the worst scores. According to the NRF 9.3 model per 100 kcal, the best scores were obtained for frozen foods, grains and legumes and milk products whereas the confectionery foods had the worst scores. According to NRF 9.3 per serving size, grains and legumes had the best scores and flavoured milks had the worst scores. A comparison of WXYfm and NRF 9.3 nutrient profiling models ranked scores showed a high positive correlation (p=0.01). The two nutrient models evaluated yielded similar results. Further studies are needed to test other category specific nutrient profiling models in order to understand how different models behave.

Nonalcoholic fatty liver disease (NAFLD) is considered one of the most important causes of chronic liver disorders in the world. Dietary pattern is a modifiable risk factor that represents the main target for the prevention and treatment of NAFLD. The aim of this cross-sectional study was to assess the impact of low-fat diet on anthropometric measurements, biochemical, and inflammatory parameters in individuals with obesity/overweight and NAFLD. A total of 108 individuals (n = 59 males and n = 49 females) aged between 19 and 65 years participated in the 12-week weight loss program. Dietary treatment plans including low-fat diets were randomly prescribed for each individual. Anthropometric measurements were collected by a trained dietitian at baseline and 12-week follow-up. Blood samples were collected for each individual at baseline and 3rd month for biochemical measurements and enzyme-linked immunosorbent assay analysis for tumor necrosis factor-α (TNF-α), interleukin (IL)-6, fibroblast growth factor-21 (FGF-21), chemerin, and irisin levels in plasma. At the end of the study, body weight, body mass index, body fat % body fat mass (kg) reduced significantly in females and males (P < .05). Moreover, reductions in waist, hip, and neck circumferences were significant in both groups. Changes in alanine aminotransferase and aspartate aminotransferase levels were significant in 3rd month. After 3 months, reductions in TNF-α, IL-6, and FGF-21 levels were significant in individuals with obesity/overweight and NAFLD. While no significant change in chemerin and irisin levels was found. These results show that low-fat diet over a 12-week period led to improvements in both anthropometric measurements and biochemical parameters in individuals with obesity/overweight and NAFLD.

BACKGROUND: Encapsulation technology has been extensively employed in recent years to enhance the efficacy and efficiency of probiotics. Nevertheless, existing studies have primarily concentrated on product efficacy, with inadequate scrutiny concerning potential effects on living organisms. This study aimed to evaluate the effects of various encapsulated probiotic strains on inflammatory responses in healthy mice, alongside their in vitro viability. Nissle (EcN) and Lactobacillus rhamnosus GG (LGG) were microencapsulated for the study.RESULTS: The differences in serum levels of Total Oxidant Status, Total Antioxidant Status, and C‐reactive protein among the groups were statistically significant (LGG, P = 0.039, P = 0.024, and P < 0.001; EcN, P = 0.019, P = 0.012, and P = 0.037, respectively). The highest levels were found in the control group, while the lowest levels were observed in the microencapsulated group. There were no significant differences in tissue tumor necrosis factor or interleukin‐6 levels for either LGG or EcN.CONCLUSION: Probiotics reduced inflammation‐related parameters in serum of healthy mice. Microencapsulation preserved viability in vitro, but in vivo no significant differences were observed in anti‐inflammatory parameters or body weight between microencapsulated and free probiotics. © 2025 The Author(s).
