Abstract Five groups of lambs (n = 9 each) were used to test the effect of plant extracts rich in hydrolysable (HT) or condensed tannin (CT) on animal performance, fatty acid composition of rumen content and meat. The control group (CO) received a concentrate-based diet without tannins supplementation. The other groups received the same diet as the control lambs plus 4% chestnut (CH) and tara (TA) extracts as a source of HT and mimosa (MI) and gambier (GA) extracts as a source of CT. Dietary CH negatively affected animal performance. The rumen content of the different groups showed comparable levels of 18:3 c9c12c15, 18:2 c9c12, 18:2 c9t11, 18:1 t11 and 18:0, whereas 18:1 t10 was greater in CO. Also, 18:1 t10 tended to be lower in the rumen of HT than CT-fed lambs. These data were partially confirmed in meat, where CO showed a greater percentage of individual trans 18:1 fatty acids in comparison with tannins-fed groups. Our findings challenge some accepted generalizations on the use of tannins in ruminant diets as they were ineffective to favour the accumulation of dietary PUFA or healthy fatty acids of biohydrogenation origin in the rumen content and lamb meat, but suggest a general action of tannins on the whole biohydrogenation process.

Five groups of lambs (n = 9 each) were used to test the effect of plant extracts rich in hydrolysable (HT) or condensed tannin (CT) on animal performance, fatty acid composition of rumen content, liver and meat. The control group (CO) received a concentrate-based diet without tannins supplementation. The other groups received the same diet as the control lambs plus 4% chestnut (CH) and tara (TA) extracts as a source of HT and mimosa (MI) and gambier (GA) extracts as a source of CT. One-way ANOVA was used to assess the overall effect of dietary treatments, tannins supplementation (CO vs. CH+TA+MI+GA) and the effect of tannin type (HT vs. CT: CH+TA vs. MI+GA) on animal performance, rumen content, liver and intramuscular FA. Dietary CH negatively affected animal performance. The rumen content of the different groups showed similar levels of 18:3 c9c12c15, 18:2 c9c12, 18:2 c9t11, 18:1 t11 and 18:0, whereas 18:1 t10 was greater in CO. Also, 18:1 t10 tended to be lower in the rumen of HT than CT-fed lambs. These data were partially confirmed in liver and meat, where CO showed a greater percentage of individual trans 18:1 fatty acids in comparison with tannins-fed groups. Our findings challenge some accepted generalizations on the use of tannins in ruminant diets as they were ineffective to favour the accumulation of dietary PUFA or healthy fatty acids of biohydrogenation origin in the rumen content and lamb meat, but suggest a generalized influence on BH rather than on specific steps.

Adipose tissue is an endocrine organ and has central role in interaction with other organs or tissues while propolis can induce lipolysis. Therefore, the aim of this study is to provide detailed information about adipose tissue homeostasis modifications and body composition during propolis supplement consumption. Twenty male Wistar albino rats (8 weeks) were divided into two groups of 10 animals each and fed for 90 days with two different types of diets: standard for the control group (diet C) and standard diet + 2% propolis (diet P). Thyroid hormones did not show differences, while ghrelin and adiponectin decreased in the group that was fed propolis. Insulin, leptin, and non-esterified fatty acids also increased along with reduced body weight and fat, in addition to increased lean mass when propolis was in the diet. We conclude that propolis could decrease ghrelin and adiponectin but increase non-esterified fatty acids and insulin secretion, which improves body composition.

Modification of lifestyle, including healthy nutrition, is the primary approach for metabolic syndrome (MetS) therapy. The aim of this study was to estimate how individual nutrition intervention affects the reduction of MetS components. Subjects diagnosed with MetS were recruited in the Lomza Medical Centre. The study group consisted of 90 participants and was divided into one intervention group (individual nutrition education group (INEG)) and one control group (CG). The research was conducted over 3 months. The following measurements were obtained during the first visit and after completion of the 3 months intervention: body mass, waist circumference, body composition, blood pressure, fasting glucose, and blood lipids. Dietary assessments were performed before and post-intervention using 3-day 24-h dietary recalls. Dietary knowledge was evaluated with the KomPAN questionnaire. The total polyphenol content of the diet was calculated. Sociodemographic and lifestyle characteristics were collected from a self-reported questionnaire. The physical activity was assessed by the short version of the International Physical Activity Questionnaire (IPAQ). It was found that the individual nutrition education was an effective method to improve the knowledge, dietary habits, and physical activity of the study participants. The modification of the diet in terms of higher intake of polyphenols (flavonoids and anthocyanins), fiber, polyunsaturated fatty acids (PUFA), PUFA n-3, and lower intake of saturated fatty acids (SFA) had a significant impact on the improvement of some MetS risk factors (waist circumference, fasting glucose, and HDL-cholesterol).

The aim of the study was to assess the influence of the addition of fish raw materials (roe or fish meat) on the quality and nutritional value of pork pâtés. The control group (n = 4) consisted of pork pâtés, I experimental group (n = 6) of pâtés with 20% addition of roe (perch and pike), and II group of pâtés with 20% addition of fish (perch and pike meat) (n = 6). The pâtés’ pH, color, and profiled texture analysis were instrumentally measured and water, protein, fat, ash, and fatty acid content were determined by reference methods. To assess the oxidative stability of lipids the measurement of peroxide number, thiobarbituric acid reactive substances and content of conjugated dienes and trienes was used. The degree of fat hydrolysis was determined on the basis of acid value. Sensory analysis was carried out using the scaling method, taking into account 12 unit quality characteristics. Products with roe and meat contained less fat (accordingly 15.9% and 14.1%) and showed lower calorific value (accordingly 225.6 and 208.6 kcal/100 g) compared to pork pâtés (20.2% of lipids, 267 kcal/100 g). Moreover, the addition of fish raw materials improved the index of nutritional quality for protein (from 3.2 to 3.9) and beneficially reduced the nutritional index for fat (from 2.2 to 1.9). Fish constituents modified, to a certain extent, the color, texture, and sensory properties of pâtés, while maintaining full acceptability in consumer assessment. The addition of fish roe significantly increased the healthful quality by improving the fatty acid profile of pâtés, in which the significantly highest content of n-3 fatty acids, including eicosapentaenoic and docosahexaenoic acids (accordingly 252.21, 43.17, and 107.94 mg/100 g product), as well the highest concentration of saturated branched chain fatty acids were determined (18.75 mg/100 g product).

The aim of this study was to compare the effect of two different types of oils in diet on the fatty acid profile in the eggs of layers and to include a particular type of oil as a supplement of feeding mixtures for layers in order to support the development of functional foodstuffs. Thirty layers fed a diet containing soybean oil constituted the control group (soybean oil is the most frequently used oil added to feeding mixtures). In the experimental group (thirty layers), soybean oil was replaced with linseed oil at the same amount (3 kg of oil per 100 kg of feeding mixture). Feeding was provided ad libitum for all days of the month. After one month, egg yolks were analysed and the fatty acid profile was compared. Significant differences (P ≤ 0.05) were found in the concentration of myristic acid that belongs to the group of saturated fatty acids. Eggs in the experimental group showed higher concentrations of myristic acid compared to the control group (0.20 g/100 g of fat and 0.18 g/100 g of fat, respectively). Highly significant differences (P ≤ 0.01) were found for heptadecanoic acid but the trend was opposite to that of myristic acid; concentrations of heptadecanoic acid in the experimental group were lower than those in the control group. Highly significant differences (P ≤ 0.01) were found for n-9 monounsaturated fatty acids where egg yolks in eggs from layers fed linseed oil contained higher concentrations of oleic acid, myristoleic acid, and palmitoleic acid. Lower concentrations of n-6 fatty acids (P ≤ 0.01) were found after the addition of linseed oil in eggs. Linseed oil showed a positive effect on n-3 fatty acids (α-linolenic acid), its concentration in the control and experimental group was 0.82 g/100 g of fat and 5.63 g/100 g of fat, respectively. The possibility of influencing the fatty acid profile in eggs is very important for the development of functional foods.

Context. Several studies have shown a link between proinflammatory activity and the presence or deficit of some fatty acids. Inflammation is associated with several diseases including diabetes.Objective. To characterize and compare the fatty acids profiles in children with inaugural type 1 diabetes, diabetic children (at least 1 year after diagnosis), and healthy children.Design. Plasma fatty acids profiles in children with inaugural diabetes, children with noninaugural diabetes, and controls, all of whom were prepubescent with a BMI < 85th percentile, were evaluated.Results. Omega-3 fatty acid levels were higher in recently diagnosed subjects with diabetes than in controls. The ratio of omega-6/omega-3 fatty acids was higher in the control population. Omega-6 fatty acid levels were higher in the nonrecent diabetic subjects than in the children with recently diagnosed diabetes, and the levels were higher in the nonrecent diabetes group compared to the control group.Conclusion. Our findings showed higher levels of alpha-linolenic acid, EPA, and DHA, as well as mono- and polyunsaturated fatty acids, in diabetic children. These findings reinforce the importance of precocious nutritional attention and intervention in the treatment of diabetic children.

In order to study the effect of dietary supplement of linseed oil on polyunsaturated fatty acids (PUFAs) in egg yolk of Gallus domestiaus, total 160 healthy Gallus domestiaus of 26-week old were randomly selected and divided into 4 groups, each of which included 40 chickens fed outdoors with an area of 63 m2 and free food and drinking water. The control group (CK) was fed the basic diet, and the experimental group was added 1, 3 and 5% of linseed oil in the fundamentals of diet (experimental group 1, 2 and 3, abbreviated as P1, P2, P3), respectively. The content of PUFA and the value of n-6 PUFA and n-3 PUFA in egg yolk were determined by gas chromatography with 24 eggs randomly selected in each group after 10th, 25th and 40th days of the commence of the experiment. We found that the levels of α-linolenic acid (C18:3n3, ALA) and docosahexaenoic acid (C22:6n3, DHA) in egg yolk were clearly higher than the CK when 3% linseed oil or 5% linseed oil were added in the diet during the three experiment periods, in which the contents of linoleic Acid (18:2n6c, LA) and arachidonic acid (C20:4n6, ARA) in egg yolk differ little between P1, P2 and P3 and the CK while the value of n-6 PUFA and n-3 PUFA in egg yolk of the P2 and P3 groups decreased significantly. The comprehensive comparisons suggested that the content of C18:3n3 and C22:6n3 in egg yolk could be clearly increased in the P2 while the value of n-6 PUFA and n-3 PUFA decreased. This study provides theoretical basis for the production of functional eggs enriched with C22:6n3 and C18:3n3.

AbstractBackgroundThe objective of the study was to compare the effect of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) dietary supplementation on their concentration in total lipids (TL) and lipid fractions of maternal and umbilical vein (UV) blood. The specific objective was to analyze the impact of EPA and DHA supplementation on pregnancy outcome and neonatal birth weight.MethodsWomen were randomly single-blinded (randomized controlled trial; ISRCTN36705743) allocated to the group receiving EPA and DHA supplementation (supplemented group) or the group receiving placebo-corn oil (control group) in the time period from January 1st, 2016 until March 1st, 2017. Women in the supplemented group (n=45) took 360 mg EPA and 240 mg DHA daily while controls (n=42) were given a placebo. Maternal and UV bloods were obtained at delivery. After lipid extraction, phospholipids (PL), cholesterol esters (CE), triacylglycerols (TG) and non-esterified fatty acids were separated by thin layer chromatography and analyzed by gas chromatography.ResultsHigher DHA concentrations in TL (37.24±21.87 mg/L), PL (13.14±8.07 mg/L) and triacylglycerols (2.24±2.21 mg/L) were recorded in mothers from the supplemented group when compared to the study group (TL 21.89±14.53 mg/L; P<0.001; PL 9.33±5.70 mg/L; P=0.013; TG 0.56±0.43 mg/L; P<0.001). Higher DHA concentrations in UV samples were found in TL (11.51±7.34 mg/L), PL (5.29±3.31 mg/L) and triacylglycerols (0.62±0.46 mg/L) from the supplemented groups compared with controls (TL 7.37±3.60 mg/L; P=0.002; PL 3.52±2.19 mg/L; P=0.005; TG 0.40±0.46 mg/L; P=0.035). The ratio of AA:DHA was lower in maternal (2.43) and UV serum (4.0) of the supplemented group than in the control group (maternal 3.85 P<0.001; UV 4.91 P<0.001).ConclusionThe study demonstrated the higher ratio of AA/DHA in the control group indicating that pregnant women on the traditional Herzegovina diet need supplementation with DHA and EPA.
