The aim of this study was to investigate the fat content and fatty acid profile in salty snack products from the Serbian market. A total of 58 different snack products from 3 categories (Baked products, Chips & flips products, Cereal products) were analyzed. The fatty acid composition was determined using gas chromatography. Total fat content ranged from 3.1 % in expanded rice to 35.7 % in potato chips. Palmitic, oleic and linoleic acids constituted > 80 % of all fatty acids (FAs) in categories Baked products and Chips & flips. Linoleic acid was more abundant in the category Cereal products (15.5-49.3 %). The trans-FAs elaidic (C18:1-9t) and linolelaidic FAs (18:2-9t, 12t) were identified in 66 % of the products. The flips products had the highest average t-FAs content (16.3 %), followed by flips group (9.3 %). Potential t-FAs intake from 100 g of analyzed products was in range 0.1-4.9 g. This study provided a large database on saturated fatty acids and t-FAs content in salty snack products and indicated that by consuming only one package of some products, the t-FAs intake could surpass the recommended maximum of 1 % of daily energy.

Both in animals and humans, alpha-linolenic acid is desaturated and elongated into eicosapentaenoic and docosahexaenoic acid. It is also incorporated into plasma and tissue lipids and its conversion is affected by levels of linoleic acid. POTENTIAL ROLE IN PATHOGENESIS OF CARDIOVASCULAR DISEASES: Diet enriched in n-3 fatty acids, especially alpha-linolenic acid, reduces the incidence of cardiac death. Studies have shown that alpha linolenic acid prevents ventricular fibrillation which is the main cause of cardiac death. Studies in rats suggest that alpha-linolenic acid may be more effective in preventing ventricular fibrillations than eicosapentaenoic and docosahexaenoic acid. Furthermore, alpha-linolenic acid is the main fatty acid decreasing platalet aggregation which is an important step in thrombosis i.e. non-fatal myocardial infarction and stroke. DIETARY SOURCES AND NUTRITION RECOMMENDATIONS: Dietary sources include flaxseed and flaxseed oil, canola oil, soybean and soybean oil, pumpkin seed and pumpkin oil, walnuts and walnut oil. Strong evidence supports beneficial effects of alpha-linolenic acid and its dietary sources should be incorporated into balanced diet for prevention of cardiovascular diseases. The recommended daily intake is 2 g with a ratio of 5/1 for linoleic/alpha-linolenic acid.

The aim of this study was to investigate the effects of lipid-lowering diet on key FA ratios in serum phospholipids and omega-3 index in erythrocyte phospholipids in moderately hyperlipidemic subjects. The study included 41 subjects, mean age 56±6 years. Nutritional habits were evaluated by food frequency questionnaire. Participants followed lipid lowering diet for 12 weeks. Energy intake of omega-6 and omega-3 FA was changed from 7.6% and 0.6% to 5.7% and 1.2%, respectively. Marked decrease in four FA ratios in serum phospholipids, i.e., omega-6/omega-3, arachidonic acid (AA)/eicosapentaenoic acid (EPA), AA/docosahexaenoic acid (DHA), AA/(EPA+DHA) and omega-3 index (EPA+DHA) was found in study subjects after lipid-lowering diet. Total cholesterol/high-density lipoprotein (HDL), low-density lipoprotein (LDL)/ HDL and triacylglycerol/HDL-cholesterol ratios positively correlated with all FA ratios, and negatively correlated with total omega-3 levels in serum phospholipids and omega-3 index in erythrocytes. Total serum omega-3 levels showed strongest association with lipoprotein ratios and positive correlation with homeostatic model assessment (HOMA) index. In conclusion, lipid-lowering diet resulted in decreased serum key FA ratios, increased omega-3 levels, and improved insulin sensitivity that may lead to a lower risk of cardiovascular disease in subjects with moderate hyperlipidemia.

The aim of this study was to determine and compare the iTFA content in frequently consumed food products by young adults from the Serbian and Slovenian market with supposedly elevated iTFA content in 2015. At the time of this study, there was no recommended limit of iTFA in both countries, and reduction of iTFA in foods was on voluntary basis. Methods: We determined iTFA content in food products, 19 from the Serbian and 22 from the Slovenian market, blinded and analysed in the same analytical run. Contents of fatty acids (FA) methyl esters were analysed by capillary gas chromatography with a flame ionisation detector. Heptadecanoic acid was used as internal standard. Individual FA along with TFA were expressed as percentages of total measured FA. The amount of each FA in the sample was then calculated from the response factor and the transformation factor of the FA from the FA methyl ester content. Results: Elaidic acid (C18:1t) was found as the most abundant TFA in analysed products, ranging from 0.52 g/100 g of total FA in chocolate candy up to 60.4 g/100 g in a salami from Serbian market. In Slovenian products, the values for elaidic acid were lower, 0.04-3.95 g/100 g of total FA, except in one type of wafers (24.3 g/100 g). Conclusions: The majority of analysed products from the Serbian and three from Slovenian market exceeded the recommended WHO and EU limit of 2% iTFA of total fat in foods. Samples of frequently consumed salami, wafers, tea biscuits, and snacks were identified as products with potentially higher burden of iTFA in diets of young adults in Serbia.

Twelve recreational female basketball players (age 29–41 years, oxygen consumption (VO2max) > 30 ml⋅kg–1⋅min–1, with training > 5 h wk–1) were randomized either to the higenamine group, or to the placebo group for 3 weeks. In order to determine ergogenic effects and safety profile of higenamine administration, we assessed the following variables before and after 3 weeks of supplementation: anthropometric parameters, resting metabolic rate (RMR), exercise testing variables, serum free fatty acids (FFAs), blood pressure, enzyme activity, urea, lipid profile, and complete blood count. There were no differences between groups in anthropometric parameters, including basal metabolic rate (BMR), RMR and body fat [p = 0.706 (Cohen’s d 0.223), p = 0.169 (Cohen’s d 0.857), and p = 0.223 (Cohen’s d 0.750), respectively], FFAs [0.43 ...

Being a complex entity, numerous uncertainties about OSA still exist, despite the extensive research on the topic. Our objectives were to evaluate human studies addressing dietary intake/nutritional status, and the quantity/types of physical activity related to OSA. The search in PubMed, Scopus, and Web of Science databases was conducted to examine relevant articles published from inception to the end of December 2022, utilizing the MeSH strings in the search strategy. Only studies published in English and conducted in humans (≥18 years) without chronic conditions (cancers, kidney/liver disease) or pregnancy, were used. Book chapters, abstracts-only, and studies in which participants did not have all three body composition components measured to identify OSA, or when body composition components could not be related to the independent/exposure variables were excluded.

In this study, analysis of fatty acid composition and TFA content in edible oils and fats along with the possible intake of trans-fat in Indian population was carried out. The analysis was carried out as per the Assn. of Official Analytical Chemists (AOAC) methodology and the results were statistically analyzed. The average TFA content in nonrefined mustard and refined soybean oils exceeded by 1.16-to 1.64-fold as compared to the Denmark limit of 2% TFA in fats and oils destined for human consumption. In branded/nonbranded butter and butter oil samples, average TFA limit exceeded by 4.2-to 9.5-fold whereas hydrogenated vegetable oil (HVO) samples exceeded the limit by 9.8-fold, when compared to Denmark standards. The probable TFA intake per day through different oils in Indian population were found to be less than WHO recommendation. However Punjab having highest consumption of HVO (-15 g/d) showed 1.09-fold higher TFA intake than the WHO recommendation, which is alarming and may be one of the factors for high cardiovascular disease mortality rate that needs further elucidation. Thus there is a need to prescribe TFA limit for edible oil, butter, and butter oil in India and to reduce the already proposed TFA levels in HVO to safeguard the health of consumers.

Inflammation is the most important factor in the genesis of vascular complication in the endstage renal disease. The serum C-reactive protein (CRP) level is a sensitive marker of systemic inflammation as well as a predisposing factor for cardiovascular and all cause mortality in patients on hemodialysis. Albumin is the negative acute phase protein and its synthesis declines during the inflammation. The patients undergoing hemodialysis have a high prevalence of protein-energy malnutrition, due to reduced protein synthesis and increased degradation. The low serum albumin levels in these patients originate from the complex setting of conditions with systemic inflammatory response as a major cause, malnutrition and overhydratation. The aim of this study was to determine the prevalence of elevated CRP levels in the dialysis patients and to analyse its correlation with serum albumin levels and other parameters of nutritional status. Methods. The study included 49 patients ...
