Antioxidant Activity and Fatty Acid Profile of Sous-Vide Beef Marinated with Kiwiberry Fruit Pulp: Effects of Level Addition and Refrigerated Storage.

The purpose of the study was to determine the antioxidant activity (AA) and fatty acid (FA) profile of sous-vide beef previously marinated in brine with a 10, 20 and 30% addition of kiwiberry (Actinidia arguta cv. 'Ananasnaya') fruit pulp, as well as changes in the parameters studied after 0, 1, 2 and 3 weeks of refrigerated storage in a vacuum package. The FA profile, FRAP (ferric-reducing antioxidant power assay), ABTS (2,2'-azinobis (3-ethylbenzthiazoline-6-acid)), total polyphenols, chlorophylls and carotenoids were also determined in the fruit pulp. Lipid indices for meat were calculated based on the obtained FA profile. The values of FRAP and ABTS of experimental meat products were significantly (p ≤ 0.05) higher than those of control samples but decreased with storage time. The proportion of unsaturated FA in the lipids of sous-vide meat was higher in samples with pulp than in control samples and insignificantly decreased with storage time. Meat marinated with kiwiberry pulp was characterized by a significantly (p ≤ 0.05) higher proportion of ALA (α-linolenic acid) and LA (linoleic acid), considerably affecting the more favorable value of polyunsaturated FA/saturated FA ratio. A troubling finding was the heightened level of palmitic acid (C16:0) in the lipids of beef subjected to 30% kiwiberry pulp, a factor recognized to play a significant role in the development of various diseases. Beef marinated with 20% kiwiberry pulp addition provides greater nutritional and health benefits than other sample variants because of optimal AA and FA profile changes during refrigerated storage.

Health Benefits of Bread Fortification: A Systematic Review of Clinical Trials according to the PRISMA Statement.

Bread is among the most common foods for the world's population. Therefore, it can be fortified to eliminate deficiencies of nutrients or be a carrier of other substances with a nutritional or physiological effect, bringing health benefits to its consumers, thus impacting sustainable health. This systematic review aimed to analyze clinical studies on the effects of bread fortification on human health. The study followed the PRISMA guidelines for transparency and utilized databases Scopus, Embase, PubMed, and Web of Science to search clinical trials focused on the effects of bread fortification on human health over the entire last decade. The methodological quality of selected studies was assessed using the Jadad scale. As a result, twenty-six studies meet the inclusion criteria. Clinical trials have shown health benefits from consuming bread fortified with vitamins (B9, C, D2, D3), minerals (K, P, Ca, Mg, Fe, Zn, Cr, Se), fiber, proteins, and polyphenolic compounds. Conclusions reveal that mandatory fortification aligns with the sustainable development goals. Thus, collaborative partnerships are essential for successful implementation and accessibility, fostering public health advances and progress developing into sustainable health.

Fatty Acid Profile and Lipid Quality Indexes of the Meat and Backfat from Porkers Supplemented with EM Bokashi Probiotic.

The study aimed to assess the effect of supplementation of pig diet with the Bokashi probiotic on the fatty acid profile of longissimus lumborum (LL) muscles and backfat. The research involved 120 hybrid pigs deriving from Naïma sows and P-76 boars. The experimental group's pigs received probiotics in their feed (containing Saccharomyces cerevisiae, Lactobacillus casei, and Lactobacillus plantarum). To analyze the fatty acid profile in intramuscular fat (IMF) of LL and backfat, 24 pig carcasses from the control group and 26 from the probiotic-supplemented group were randomly selected. Probiotic supplementation increased the Atherogenic Index, reduced the proportion of C20:4, and increased C12:0 and C18:2 n-6 in IMF LL, without affecting ΣSFA, ΣMUFA, and ΣPUFA. In backfat, probiotic supplementation decreased C18:1 and C18:2 n-6 proportion and increased C18:3 n-3, C20:3 n-6, and C20:4 n-6. These changes resulted in significantly higher ΣMUFA, ΣPUFA, PUFA Σn-3/Σn-6, and lower Saturation Index (SI). From a consumer health and technological point of view, probiotic supplementation improved the lipid profile of backfat to a greater extent than LL muscle. Bokashi, at a dose of 3 g/kg of feed in the last stage of pig production, had no significant effect on the fatty acid profile of the meat.

Goose Meat as a Source of Dietary Manganese-A Systematic Review.

Manganese is a trace element with essential physiological functions that should be supplied to animals and humans through diet. Goose meat is prevalent in many regions of the world. Therefore, the aim of the study was a systematic review (PRISMA statement, 1980-2022) of the content of Mn in raw and cooked goose meat and their relation to the recommended intake at the level of adequate intake (AI) and the nutrient reference values-requirements (NRV-R). The literature analysis shows that the content of Mn in goose meat depends on the breed, type of muscles, the presence of skin, and the cooking method used. AI level recommendations for Mn intake range from 0.003 to 5.50 mg/day, depending on the country, age, and gender. Consumption by adults (regardless of sex) of 100 g of domestic or wild goose meat covers the daily AI per Mn in various percentages, depending on the type of muscles (more Mn in leg muscles), presence of skin (more Mn in skinless muscles), and thermal treatment (pan fried with oil, grilled, and cooked meat contains more). Placing information on the Mn content in goose meat and the percentage of NRV-R on the packaging may be valuable information for the consumer in making food choices to diversify the diet. There are few studies on the content of Mn in goose meat. Therefore, it is reasonable to conduct research in this area.

The Energy and Nutritional Value of Meat of Broiler Chickens Fed with Various Addition of Wheat Germ Expeller.

The study concerns the effect of wheat germ expeller (WGE) as a feed additive given to male Ross-308 broiler chickens on their meat's energy and nutritional value, and coverage of nutrient reference values-requirements (NRV-R) of consumers for particular minerals. The chickens in the control group (CT-Control Treatment) were fed a standard complete mix. The experimental groups (EX5, EX10, EX15) were given a feed in which wheat middling was replaced with 5, 10, and 15% WGE. The breast and thigh muscles of 32 randomly selected chickens (8 in each group) were analyzed. More water, crude protein, P, Mg, Fe, Cu, and Mn were determined in the breast muscles, and more crude fat, crude ash, Ca, and Zn in the thigh muscles. Chickens from the CT group consumed significantly (p ≤ 0.01) less feed per body weight than those from groups EX5 to EX15, but achieved the highest body weight per 100 g of consumed feed. A higher (p ≤ 0.01) feed, energy, crude protein, and crude fat intake was observed in groups EX5 to EX15 compared to CT. The higher (p ≤ 0.01) value of protein efficiency ratios was indicated in the CT group. The WGE additive did not impact the muscles' energy values but affected the nutritional value. The daily consumption of 100 g of breast muscles to a large extent covers the consumer NRV-R for P, Mg Fe, Cu, and Mn. However, thigh muscles cover the NRV-R to a greater extent for Ca and Zn. The EX15, EX5, and EX10 muscles covered most of the NRV-R for P, Ca, and Mg, while the CT muscles did the same for Zn and Mn. Adding 5% WGE to broiler feed is optimal as it does not impair the nutritional value of the muscles.

Evaluation of changes in eating habits of chronically mentally ill patients residing in 24-hour social welfare home, subject to various forms of health-promoting education.

INTRODUCTION: One of the decisive factors in maintaining good health and physical and mental fitness is proper nutrition. Its role becomes particularly important when a disease occurs, including chronic and mental illness. AIM OF THE STUDY: This study was aimed at investigating whether, and to what extent, it is feasible to conduct health-promoting nutritional education and to implement principles of correct nutrition in chronically mentally ill patients residing in a 24-h Social Welfare Home (SWH). MATERIAL AND METHODS: 52 people staying in the 24-hour SWH for chronically mentally ill participated in the study. Nutritional education was conducted by a dietitian with whom a psychologist, nurse and physiotherapist collaborated. Nutritional education was aimed at accepting changes in the way of nutrition by changing the composition otfthe diet and food preparation, changing eating behavior (throwing food under the table, taking food from other residents, etc.) and changing the structure of own purchases. RESULTS: One year after the correction of the diet and nutritional supervision, a statistically significant increase in the consumption of vegetables, fruit, cottage cheese, fish and vegetable fats and a decrease in the consumption of white wheat bread, rennet cheese, cold meats and sugar and sweets. In the assortment of women's own purchases, the amount of cold cuts, sweets and cakes decreased, and apples and dairy products appeared. In men, the amount of cold cuts, cheese, cakes and sweetened drinks decreased, and fruits and fermented milk drinks appeared. A significant reduction in the value of the glycemic load was found: 2nd breakfasts, snacks and the value of a 24-hour diet. CONCLUSIONS: It was found that multidirectional pro-health nutritional education of chronically mentally ill people is reflected in their nutritional behavior. The fact that the respondents are aware of the influence of the diet on their health also translates into a change in the range of their own purchases.

Assessing effects of diet alteration on selected parameters of chronically mentally ill residents of a 24-hour Nursing Home. Part 2. Effects of nutritional changes on anthropometric parameters and composition of the body. / Ocena wplywu zmian sposobu zywienia na wybrane parametry u osób przewlekle psychicznie chorych, przebywajacych w calodobowym DPS. Cz. 2: Wplyw zmian w sposobie zywienia na parametry antropometryczne i sklad ciala.

OBJECTIVES: The study was aimed at finding out whether, and how, changes in dietary habits would be reflected in anthropometric parameters and body composition. METHODS: Anthropometric measurements (Martin's technique) were taken on 52 chronically mentally ill patients, twice: before and a year after diet correction. The patients' body composition was examined, directly after the measurements, by bioelectric impedance analysis (BIA) in tetragonal arrangement, using a Bodystat ®1500MDD device. RESULTS: Changes in dietary habits were reflected in a significant reduction of body weight, BMI, and waist circumference in schizophrenic women; WHR in men with other diseases increased significantly. BMI analysis showed an increase in the percentage of normal-weight schizophrenic women and men, a decrease in the proportion of underweight women and men, and an increase in the proportion of individuals with normal weight suffering from other diseases. Both groups showed beneficial changes in body composition (increased content and percentage of fatless body weight and water, reduced content and percentage of fat tissue). These changes were statistically significant only in men suffering from other diseases and concerned the increased content of fatless body weight. CONCLUSIONS: Changes in dietary habits enhanced body weight reduction in overweight and obese individuals and resulted in desired changes in BMI, WHR, and body composition. The body fat content was distinctly reduced, with no concurrent changes in the fatless body weight and/or water content. Changes in dietary habits were beneficial for the nutritional status of undernourished patients or those with low body weight.

Impact of various types of heat processing on the energy and nutritional values of goose breast meat.

The purpose of this study was to examine the impact of various types of heat processing used by consumers (water bath cooking WBC, oven convection roasting OCR, grilling G, pan frying PF) on the energy and the nutritional value of goose breast meat (with and without skin). The material used in the study comprised 72 breast muscles cut from carcasses of 17-wk-old White Koluda geese. The energy value (MJ), the chemical composition (water, fat, protein, ash) and mineral composition (phosphorus P, sodium Na, calcium Ca, potassium K, magnesium Mg, iron Fe, zinc Zn, cooper Cu, manganese Mn) were determined in both raw and thermally processed muscles. It has been concluded that various methods of heat processing have a significant impact on the energy and nutritional values of meat. From a dietary point of view, the most beneficial was OCR meat without skin, and WBC, OCR, PF meat with skin as well, since it had the lowest energy value as well as content and retention of fat, phosphorus, and sodium. However, as for the content of the other minerals and their retention, WBC seems to be the optimal form of heat treatment of skinless muscles. 100 g of such meat provides 3.1; 33.7; 145; 180 and 9% Nutrient Reference Values-Requirements (NRVs-R) for Ca, Mg, Fe, Cu, and Mn respectively in a diet of an adult person. As for meat with skin, the optimal method of heat processing to retain minerals is grilling. 100 g of meat processed in this way provides 3.9; 39.7; 125.7; 175; 6 and 12.7% NRVs-R of Ca, Mg, Fe, Cu, and Mn. It follows from the above information that goose breast meat, as analyzed here, cannot be considered as a source of calcium since it provides less than 4% of NRVs-R. The results of the study will be useful for the consumers' nutritional choices. The geese breast meat, depending on the heat processing used and the content of skin, may be a valuable component of a varied diet, providing nutrients and minerals.

The protein and fat quality of thigh muscles from Polish goose varieties.

This study aimed to evaluate the nutritional value of thigh meat from 4 Polish geese varieties. Protein, fat, and cholesterol content, as well as amino acid and fatty acid profiles, were determined. Based on the percentage of amino acid in protein and fatty acids in meat lipids, the health lipid indices were calculated. The experimental material covered thigh muscles from 17-week-old Kartuska (Ka), Suwalska (Su), Lubelska (Lu), and Kielecka (Ki) geese reared in a semi-intensive system. Muscle protein content did not differ significantly between varieties. The protein content of the Ka, Su, Lu, and Ki goose meat was deemed high-value as it contained all the essential amino acids in the proportions consistent with standard protein values. The muscles of all the researched geese varieties were characterized by a high level of Lys, which indicates that this meat is a good source of it (AASLys 240-280%). Current findings showed that polyunsaturated fatty acids (PUFA)/saturated fatty acids (SFA) and PUFA n-6/n-3 ratios in Ka, Su, Lu, and Ki muscles were found to be within the optimum values for human diets. No significant differences were observed in monounsaturated fatty acids, PUFA, and unsaturated fatty acids (UFA) between the analyzed muscles. The meat of Ka and Su contained significantly more lipids than Lu and Ki. A more beneficial amino acid profile was found in Ka meat due to a higher content of PUFA n-3 and the best n-6/n-3 ratio in comparison with other varieties. The muscles of the Ka variety also contained the least cholesterol. However, the Ki goose muscles stood out among other varieties with the least percentage of SFA, the highest share of docosahexaenoic acid (C 22:6 n-3), as well as the most beneficial value of the following indices: UFA/SFA, hypocholesterolemic fatty acid/hypercholesterolemic fatty acid ratio, and nutritive value index. The thigh muscles of Ka, Su, Lu, and Ki were characterized by an atherogenicity index that met the levels of recommended values (<1) in the diet of a human being, while the thrombogenicity index was slightly higher than the recommended value (<0.5).

Fatty acid profiles and health lipid indices in the breast muscles of local Polish goose varieties.

The aim of this study was to evaluate the fatty acid profile and health lipid indices of meat from 3 Polish local goose varieties (Romanian-RO, Pomeranian-PO, and Subcarpathian-SB) and the commercial cross White Koluda goose (W31). Birds were fed ad libitum with the same complete feeds until 17 wk of age. The geese (n = 72) with body weight close to the arithmetic mean in particular flock were fasted for 12 h and slaughtered in an experimental slaughterhouse (18 females in each flock). Carcasses were stored at 2 to 4°C for 24 h. The breast muscles (m. pectoralis major) were cut out from the left side of carcass, separately vacuum-packed, and stored at -80°C until analysis. Fatty acid profile of meat was determined by gas chromatography and health lipid indices were calculated. The W31 muscles had a higher percentage of C 18:0 and a lower of C 16:0 than those of RO, PO, and SB geese. The W31 muscles were characterized by a significantly higher proportion of monounsaturated fatty acids (46.5%) than remaining ones (43.28%-PO, 43.38%-SB, and 44.24%-RO). The lowest proportion of polyunsaturated fatty acids was established for W31 muscles (22.05%). The breast muscles of RO, SB, and PO had more favorable polyunsaturated n-6 and n-3 fatty acid (PUFA)/ saturated fatty acid (SFA) ratio (0.85, 0.82, 0.83, respectively) than W31 geese (0.72). The current findings showed that UFA/SFA, PUFA/SFA, and PUFA n-6/n-3 ratios in RO and SB muscles were within the optimum values for human diets. No significant differences were observed in the atherogenic, thrombogenic, and hypocholesterolemic/hypercholesterolemic indices between the analyzed muscles. Commercial W31 geese breast muscles showed a lower value (43.90%) of peroxidizability index (PI) compared to SB (52.88%), PO (53.93%), and RO (53.47%). However, the higher values of the PUFA/SFA and PI in the meat of SB, PO, and RO birds may indicate a higher prohealth value of their meat.
