A crop of high nutritional quality and health maintenance value : The importance of tartary buckwheat breeding
Ivan Kreft, Aleksandra Golob, Mateja Germ, 2023, pregledni znanstveni članek

Povzetek: Abstract Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn.), originating in the Himalayan area, is cultivated in central Asia and northern, central, and eastern Europe. Tartary buckwheat grain and sprouts are rich in flavonoid metabolites rutin and quercetin. The synthesis of flavonoids in plants is accelerated by UV-B solar radiation to protect the plants against radiation damage. During Tartary buckwheat food processing, a part of rutin is enzymatically converted to quercetin. Rutin and quercetin are able to pass the blood–brain barrier. Studies have investigated the effects of rutin and quercetin on blood flow to the brain, consequently bringing more nutrients and oxygen to the brain, and causing improved brain function. In addition to the impact on blood flow, rutin and quercetin have been shown to have antioxidative properties. The goals of breeding Tartary buckwheat are mainly to maintain and enhance the high nutritional quality. The goals could be reached via the breeding of Tartray buckwheat for larger cotyledons. Other main breeding efforts should be concentrated on the easy husking of the grain, the prevention of seed shattering, and the improvement in growth habits to obtain uniformity in grain ripening and a stable and high yield.

Total polyphenol content and antioxidant activity of rutabaga (Brassica napus L. var. napobrassica) roots
Monika Cifrová, Alena Vollmannová, Tomáš Tóth, Marek Šnirc, Ivan Kreft, 2024, pregledni znanstveni članek

Povzetek: This study aimsto determine the totalcontent of polyphenols and the antioxidant activity by DPPH spectrophotometricallyin rutabaga (Brassica napusL. var. napobrassica) samples, cultivated in the Trenčín region, in the Púchov district, at the border of the White Carpathian and Javorníky mountains, Slovakia. For analysis were used three types of rutabaga, named after the collection sites(Mestečko, Lúky 1, Lúky 2). The total polyphenol content in rutabaga was ranging from 2.41 (Mestečko) to 2.82 mg GAE.g-1dry weight (Lúky2).It was established that that the studied rutabaga samplesdo not show a significant difference in the total content of polyphenols between the collection locations.In theantioxidant activity of rutabaga, differences were confirmed in AAs. A statistical difference was established between locations Lúky 2 and Mestečko.DPPH radical scavenging activity values were from 5,19 (Mestečko) to 7,49 μmol TE.g-1 DW (Lúky 2). Spearman's test showed a positive relationship between both methods used. Theseresults confirm the promising potential of rutabaga use in functional food preparation.

A systematic assessment of the revised Nutri-Score algorithm : potentials for the implementation of front-of-package nutrition labeling across Europe
Edvina Hafner, Igor Pravst, 2024, pregledni znanstveni članek

Povzetek: Front-of-package nutrition labeling (FOPNL) is an important public health tool, and the introduction of harmonized FOPNL in Europe is one of the most ambitious food labeling changes in decades. Nutri-Score (NS) has been considered for implementation across Europe. However, NS is subject to strong opposition, particularly from the food industry and some agricultural sectors (such as cheese and cured meat), but also from some nutrition scientists and public health professionals, which highlights that the system is not sufficiently aligned with food-based dietary guidelines and the latest scientific literature. These concerns were recently addressed in a revised version of NS (NS2023), aiming to overcome the limitations of its predecessor (NS2021). Our aim was to assess whether these limitations were addressed and to investigate their alignment with dietary guidelines. A systematic literature review identified 20 limitations of NS, assigned to 3 groups (Food-based, Component-based, and Other Dimensions of Food Quality). Subsequent assessment of NS employed a large representative branded food database of 19,510 pre-packed foods. Alignment with dietary guidelines was assessed based on agreement with the WHO Europe nutrient profile (WHOE). NS2023 was shown as notably stricter compared to NS2021 (7% fewer products received the higher grades A or B) and more aligned with WHOE (κNS2021 = .59, κNS2023 = .65). Overall, most (65%) of the limitations were addressed to some extent; these were mostly Food-based limitations, followed by Component-based, whereas the Other Dimension of Food Quality (processing, sustainability, portion sizes) remained mostly unaddressed. We can conclude that the revised NS2023 increased its potential for implementation across Europe. Our review identified all limitations, relevant or not, which were mentioned in the scientific literature. Therefore, some mentioned limitations may never be solvable in the scope of nutrient profiling. Others could be further addressed by adaptation of the visual presentation, but increased complexity of the labeling message would also reduce the potential of the FOPNL to support consumers in healthier food choices. Additional research is also necessary to explore the potential impact of the revised NS2023 on food reformulation and its perception among consumers.

Assessing the average sodium content of prepacked foods with nutrition declarations : the importance of sales data
Živa Lavriša, Igor Pravst, 2014, izvirni znanstveni članek

Povzetek: Processed foods are recognized as a major contributor to high dietary sodium intake, associated with increased risk of cardiovascular disease. Different public health actions are being introduced to reduce sodium content in processed foods and sodium intake in general. A gradual reduction of sodium content in processed foods was proposed in Slovenia, but monitoring sodium content in the food supply is essential to evaluate the progress. Our primary objective was to test a new approach for assessing the sales-weighted average sodium content of prepacked foods on the market. We show that a combination of 12-month food sales data provided by food retailers covering the majority of the national market and a comprehensive food composition database compiled using food labelling data represent a robust and cost-effective approach to assessing the sales-weighted average sodium content of prepacked foods. Food categories with the highest sodium content were processed meats (particularly dry cured meat), ready meals (especially frozen pizza) and cheese. The reported results show that in most investigated food categories, market leaders in the Slovenian market have lower sodium contents than the category average. The proposed method represents an excellent tool for monitoring sodium content in the food supply.

Iodisation of salt in Slovenia : increased availability of non-iodised salt in the food supply
Katja Žmitek, Igor Pravst, 2016, izvirni znanstveni članek

Povzetek: Salt iodisation is considered a key public health measure for assuring adequate iodine intake in iodine-deficient countries. In Slovenia, the iodisation of all salt was made mandatory in 1953. A considerable regulatory change came in 2003 with the mandatory iodisation of rock and evaporated salt only. In addition, joining the European Union's free single market in 2004 enabled the import of non-iodised salt. The objective of this study was to investigate the extent of salt iodising in the food supply. We examined both the availability and sale of (non-)iodised salt. Average sales-weighted iodine levels in salt were calculated using the results of a national monitoring of salt quality. Data on the availability and sales of salts were collected in major food retailers in 2014. Iodised salt represented 59.2% of the salt samples, and 95.9% of salt sales, with an average (sales-weighted) level of 24.2 mg KI/kg of salt. The average sales-weighted KI level in non-iodised salts was 3.5 mg KI/kg. We may conclude that the sales-weighted average iodine levels in iodised salt are in line with the regulatory requirements. However, the regulatory changes and the EU single market have considerably affected the availability of non-iodised salt. While sales of non-iodised salt are still low, non-iodised salt represented 33.7% of the salts in our sample. This indicates the existence of a niche market which could pose a risk of inadequate iodine intake in those who deliberately decide to consume non-iodised salt only. Policymakers need to provide efficient salt iodisation intervention to assure sufficient iodine supply in the future. The reported sales-weighting approach enables cost-efficient monitoring of the iodisation of salt in the food supply.

Viromska analiza RNA virusov v vzorcih Triglavskega ledenika in ledenika pod Skuto
Kristina Andrejc, Maša Jarčič, Ion Gutiérrez-Aguirre, Denis Kutnjak, Katarina Bačnik, 2025, izvirni znanstveni članek

Povzetek: V ledenikih se kljub nizkim temperaturam in omejeni količini dosegljive vode ter hranil skriva velika biološka raznolikost. V ledeniških mikrobnih skupnostih prevladujejo bakterije, alge in glive. Znanje o virusih v teh ekstremnih okoljih pa je omejeno, kar smo želeli nasloviti z viromsko analizo slovenskih ledenikov: Triglavskega ledenika in ledenika pod Skuto. Iz koncentriranih vzorcev staljenega ledeniškega ledu smo izolirali ribonukleinske kisline (RNA), jih pomnožili z naključnimi oligonukleotidnimi začetniki in netarčno določili njihova zaporedja s platformo Illumina. S pomočjo bioinformatskih analiz smo v pridobljenih podatkih poiskali virusna zaporedja in jih taksonomsko uvrstili. Odstotki odčitkov, ki so se klasificirali kot virusni, so bili pričakovano nizki. Kljub osredotočenosti na opis raznolikosti RNA virusnih zaporedij, smo v vseh vzorcih slovenskih ledenikov najbolj pogosto zaznali virusne odčitke, ki so pripadali DNA bakteriofagom, klasificiranim v svet Duplodnaviria. Virusna zaporedja odkrita v vzorcih slovenskih ledenikov so večinoma izkazovala nizke identitete z znanimi virusnimi zaporedji iz podatkovnih baz, kar kaže na prisotnost številnih novih virusnih vrst. Daljša sestavljena virusna zaporedja verjetno predstavljajo celotne genome novo odkritih RNA virusov (npr. virusna zaporedja iz skupine toti-podobnih in picorna-podobnih virusov). Za taka zaporedja smo s filogenetskimi analizami pokazali, katerim znanim virusom so najbolj sorodni in kakšne organizme potencialno okužujejo. Raziskava viroma slovenskih ledenikov predstavlja prvi vpogled v prisotnost virusov v teh okoljih pri nas in razkriva, da se v njih skriva velika in neraziskana raznolikost teh bioloških entitet.
