Sorghum bicolor (L.) Moench is an increasingly important crop grown in many countries as a food source due to its excellent nutritional value, drought and pest resistance, and gluten-free properties. In this study, the bioactive profiles and antioxidant potentials of brans of six sorghum varieties were evaluated using spectrophotometric methods. The effects of weather and environmental conditions and different nitrogen nutrition were also evaluated. The bran of red varieties contained a higher amount of polyphenols and tannins and exhibited higher antioxidant capacities than the bran of white varieties, with the exception of one red genotype. The highest total polyphenol contents were measured in samples from two red varieties (Zádor, Alföldi1) with 1084.52 ± 57.92 mg 100 g⁻¹ GAE and 1802.51 ± 121.13 mg 100 g⁻¹ GAE values, respectively, while condensed tannin content varied between 0.50 mg g⁻¹ and 47.79 mg g⁻¹ in sorghum brans. Red varieties showed higher antioxidant activities/capacities with 70–281 µmol TE g⁻¹ and 71–145 µmol TE g⁻¹ for DPPH and TEAC. Correlation analysis showed a strong interaction between DPPH, TEAC, and the amounts of polyphenols and tannins, but not with FRAP values. In conclusion, red-colored varieties are a good source of polyphenols, but seed color alone is not enough to determine the nutritional value of a genotype, and the environmental conditions greatly affect the bioactive profile of sorghum.

Background/Objectives: Food insecurity remains a growing public health concern among university populations, particularly international students who often face financial constraints, limited social support, and cultural adaptation challenges. This study investigated the association between food insecurity and dietary diversity among international students in Hungary, a population for whom empirical evidence remains limited. Methods: A cross-sectional survey was conducted among 380 international university students using a structured questionnaire comprising sociodemographic items, the Food Insecurity Experience Scale (FIES), and a quantitative Food Frequency Questionnaire (FFQ). Dietary diversity was assessed through Food Group Diversity Score (FGDS) and Food Variety Score (FVS). Statistical analyses included chi-square tests, ANOVA, correlation analyses, and multiple regression using IBM SPSS 28.0. Results: Overall, 62% of participants experienced food insecurity, with 25% moderately and 20% severely food insecure, while 17% were classified as mildly food insecure. While 97% achieved high dietary diversity, only 31% exhibited high food variety. Group comparisons indicated differences in FGDS across food security categories (p = 0.006), whereas FVS did not differ significantly (p = 0.411). In multivariable regression models adjusting for socioeconomic and behavioural factors, food security status was not independently associated with FGDS or FVS. However, scholarship status, monthly income, employment, and meal skipping were significant predictors of dietary diversity indicators. Conclusions: These findings suggest that while food insecurity is prevalent among international students, socioeconomic resources and behavioural factors may play a more prominent role in shaping dietary diversity outcomes. Universities and policymakers should prioritise equitable food access, culturally inclusive meal services, and ongoing monitoring of student food security to promote nutrition equity and academic well-being.

Background: International students are exposed to new food environments that may influence their dietary behaviours. While dietary diversity has been widely studied, less attention has been given to food variety, which reflects the number of individual food items consumed. This study assessed food variety, its relationship with unhealthy food consumption, and associated sociodemographic and behavioural factors among international students in Hungary. Methods: A cross-sectional survey was conducted among 380 international students enrolled in Hungarian higher education institutions. Data were collected using a structured questionnaire incorporating a Food Frequency Questionnaire (FFQ). FVS and UFCS were calculated, and associations were examined using descriptive statistics, Pearson correlation, and multivariable linear regression analyses. Results: The mean FVS was 62.7 ± 26.7. Cereals, vegetables, and milk and dairy products were consumed by all participants, whereas fish and other seafood (61.6%) and white tubers and roots (67.9%) were the least frequently consumed food groups. A very strong positive correlation was observed between FVS and UFCS (r = 0.930, p < 0.001). This association remained strong after excluding unhealthy food items from the FVS (aFVS; r = 0.862, p < 0.001). In multivariable analyses, higher monthly income and employment were positively associated with FVS and UFCS, whereas scholarship status, postgraduate study, and following a special diet were negatively associated with both outcomes. Conclusions: Food variety among international students in Hungary varied considerably and was strongly associated with unhealthy food consumption, indicating that greater food variety did not necessarily correspond to healthier dietary patterns. These findings highlight the importance of considering both the diversity and nutritional quality of foods consumed when assessing dietary behaviours and designing nutrition interventions for international students.

Hungary and Moldova are excelling in unique wines and alcoholic beverages that could qualify for the protected geographical indication (PGI) by emphasizing parameters attributable to the geographical area, production or processing methods. In this study, we have assessed some parameters of wine and brandy samples looking for specificities. The studied samples were of Moldovan and Hungarian Cabernet Sauvignon red wines, Hungarian Furmint white wines, and Moldovan wine distillate/brandy called Divin. The assessed samples were evaluated for: total polyphenol and flavonoid, ethanol, malic, citric, lactic, tartaric acids, reducing sugar, glycerol, carbon dioxide, total and free SO₂content as well as for total acidity, volatile acidity, pH, and wine density.Our results indicate that despite the relatively close geographical vicinity of Hungary and Moldova, the wines produced in the two countries have specific composition, antioxidant activity, and sensorial properties. Thus, the registration of such wines as PGI is clearly justified, and such a label itself does represent a competitive advantage worth promoting.
