Full textAbstract:
Abstract Mineral nutrition during pregnancy has long been known to impact fetal growth and development. This is evidenced by a multitude of mineral deficiency-related causes for embryonic loss, abortion, stillbirth, or neonatal death, including poor or inappropriate fetal development that can be either reversible or irreversible postnatally. Both macro and trace mineral needs of the dam are known to increase with the fetal growth of advancing gestation due to greater metabolic stress and demand, as well as tissue development and deposition in the fetus. Fetal deposition of many trace minerals is especially important for neonatal use while consuming milk with low mineral concentrations and facing a multitude of immune challenges. In the last 2 decades, many laboratories have focused on “developmental programming,” or the effects of maternal nutrition on fetal and neonatal development and ultimately long-term health and productivity of livestock. Despite this, the role of macro and trace minerals in short-and long-term consequences of developmental programming is still unclear for many minerals and species. Taken together, research in ruminants and swine demonstrate that mineral intake and source during pregnancy can have a large effect on fetal growth and development that lasts into the neonatal and pre-weaning periods. Some studies suggest that supra-nutritional mineral intake may have a positive benefit during gestation or neonatal periods. Moreover, some data suggest that mineral requirements may be greater than currently thought to accommodate the rapid fetal growth and preparation for lactation that occurs during late gestation. Continued research is necessary to determine mineral requirements of livestock during pregnancy, especially when considering their long-reaching subsequent effects on offspring. Additionally, increased understanding of perinatal transfer of trace minerals can aid in our management of pregnant dams and their offspring.

Full textAbstract:
The trace mineral requirements of grazing beef cattle are often complicated by different environmental factors, such as the lack of specific trace minerals or the presence of trace mineral antagonists in forage. Nearly every region of the world has specific implications related to trace mineral nutrition of grazing cattle. Since forage is the most significant contributor to trace mineral nutrition, it is important to consider the concentrations of trace minerals and antagonists and how they may impact the performance of cattle consuming them. This review attempts to provide an update on the trace minerals commonly found to be inadequate in forage, supplementation strategies to address deficiency including a discussion on supplemental trace mineral source, and the complications presented by mineral antagonists. Although the review focuses on beef cattle grazing systems of the United States, the information herein is derived from both extensive native range and intensive planted pasture.

Full textAbstract:
The amount of silk produced by silkworms is influenced by several factors. The silkworm's nutrition is the most important element for good quality cocoon and silk production as it is dependent on the healthiness of the silkworm. Health, growth and resistance to biotic factors are directly dependent on the nutrition of the silkworm which is derived from the food. Consuming a well-balanced nutritious food is particularly important for silkworms, since they only consume throughout their larval period. Among the different nutritional requirements by the silkworm, minerals plays an important role. Minerals are not synthesized within insects, although they are essential elements and affect various metabolic processes. Minerals affect the growth and development of larva, economic cocoon characters and silk yield. Many functions of the neuromuscular, reproductive and hormonal systems among others can be efficiently controlled by adding micronutrients and trace elements such as minerals to the diet.

Full textAbstract:
Aquatic animals have unique physiological mechanisms to absorb and retain minerals from their diets and water. Research and development in the area of mineral nutrition of farmed fish and crustaceans have been relatively slow and major gaps exist in the knowledge of trace element requirements, physiological functions and bioavailability from feed ingredients. Quantitative dietary requirements have been reported for three macroelements (calcium, phosphorus and magnesium) and six trace minerals (zinc, iron, copper, manganese, iodine and selenium) for selected fish species. Mineral deficiency signs in fish include reduced bone mineralization, anorexia, lens cataracts (zinc), skeletal deformities (phosphorus, magnesium, zinc), fin erosion (copper, zinc), nephrocalcinosis (magnesium deficiency, selenium toxicity), thyroid hyperplasia (iodine), muscular dystrophy (selenium) and hypochromic microcytic anemia (iron). An excessive intake of minerals from either diet or gill uptake causes toxicity and therefore a fine balance between mineral deficiency and toxicity is vital for aquatic organisms to maintain their homeostasis, either through increased absorption or excretion. Release of minerals from uneaten or undigested feed and from urinary excretion can cause eutrophication of natural waters, which requires additional consideration in feed formulation. The current knowledge in mineral nutrition of fish is briefly reviewed.

Abstract The science associated with mineral nutrition is evolving at an accelerated pace. Some topics of investigation have persisted for decades; typical examples include clarification of mineral requirements, evaluation of mineral sources, definition of mineral bioavailability and physiological and metabolic interactions among minerals, to name a few. The fact that these topics have endured for so long serves to illustrate their importance to our craft, as well as the increasing sophistication of the science available to delve more deeply into our understanding of mineral nutrition. Newer topics that involve minerals directly and/or indirectly are attracting increasing attention – and for good reason. As one example, there is a growing body of data pointing to oxidative stress as a relevant issue in modern pork production. As another, the interaction of minerals with fiber has received considerable interest in the past, but recently, the topic has been further elevated by health and environmental concerns. While the above might be considered typical classical nutrition topics, mineral nutrition can also be viewed in a more holistic manner. To what extent is mineral nutrition involved in the observed increase in sow mortality in the past decade? How can and should mineral nutrition be included in precision feeding programs? What further roles of mineral nutrition might be involved in environmental sustainability? Where do we stand on the involvement of mineral nutrition in acid-base balance and does it have greater value in production today than previously considered? This presentation will consider current examples of how mineral nutrition impacts applied swine nutrition as well as overall pork production.

Purpose – Seeds and nuts include many dietary minerals as well as trace metals. It is very important to determine the nutritional mineral values in seeds and nuts. Many minerals can be analyzed simultaneously in low concentrations by using inductively coupled plasma-atomic emission spectroscopy. This paper aims to evaluate nutritional values of dietary and trace minerals in selected seeds and nuts. Design/methodology/approach – Dietary minerals in the sunflower seed (Helianthus annuus), pumpkin seed (Cucurbita pepo L.), peanut (Arachis hypogaea) and corn (Zea mays L.) samples collected from the markets in Sakarya city of Turkey have been analyzed. Two digestion procedures were applied by using hydrochloric acid solution and the mixture of nitric acid and hydrogen peroxide solution. Findings – In the evaluation of the mineral contributions of the nuts, the micro-mineral contributions (Cu, Fe, Zn, Mn and Se) were found at higher values than the macro-minerals (Ca, Mg, K and Na). Potassium was determined as the most abundant mineral, and sodium was found at lower levels. The results showed that nuts are trace mineral suppliers and possible Na-K regulator foods in human nutrition. Social/implications – The obtained results for the mineral profile and daily intake values provide useful information that could sensitize the people on the consumption of seeds and nuts. Originality/value – Findings from the digestion procedures and the assessments based on the recommended daily intakes have got valuable impact.

Full textAbstract:
Athletes’ nutrition optimization is very important for the nutritional support in all sport specializations. Macronutrients, as well as minerals and vitamins, are functionally active components that play an important role in nutrition of athletes especially in endurance sport. Optimal use of diets, including specialized sport nutrition, normalizes biochemical, immune, endocrine functions and restores athletes’ energy balance at different stages of sport exercises. Non-optimal athletes’ nutrition of different age groups, inadequate to their physiological needs, and no personalized approach to athletes’ diets, violate their right to adequate safe nutrition, according to international standards and criteria. Nutritional factors are one of the most important key factors in the risk prevention measures for a large number of diet-dependent diseases (e.g. digestive, liver, pancreas, cardiovascular system, endocrine system, and kidney diseases). The review presents the information on energy requirements, balance and availability, types and content of functional products for athletes. It also gives an overview of the specialized food market in Russia.

Full textAbstract:
This review explores the potential of microalgae as a sustainable and nutritionally rich alternative for mineral supplementation in poultry diets, addressing both the opportunities and challenges in this emerging field. Poultry nutrition, pivotal to the health and productivity of birds, traditionally relies on inorganic and organic mineral sources which, while effective, raise environmental and economic concerns. Microalgae offer a promising solution with their high contents of essential minerals, proteins, vitamins, and bioactive compounds. This review delves into the nutritional profiles of various microalgae, highlighting their rich contents of minerals which are crucial for physiological processes in poultry. It examines the bioavailability of these minerals and their impact on poultry health and productivity. Furthermore, it evaluates the environmental sustainability of microalgae cultivation and acknowledges the challenges in using microalgae in poultry diets, particularly in terms of the economic viability of large-scale production and the consistency of nutrient composition. It discusses the importance of rigorous safety assessments and regulatory compliance, given the potential risks of toxins and heavy metals. Overall, this analysis aims to provide a clear understanding of the role microalgae could play in poultry nutrition and address sustainability challenges in animal agriculture while also considering future perspectives and advancements needed in this field.

Full textAbstract:
The efficiency of chelated forms of trace minerals in poultry nutrition and the trace minerals requirements of poultry were discussed in this review. Trace minerals are essential for all farm animals, and these minerals, individually or together with other mineral, take part in many events such as metabolic activities, development and repair of different tissues, growth, immune and reproductive systems. In the last years, lots of studies related to different organic forms of trace minerals on the effects of broiler and laying hens were carried out. The results of these studies have showed that organic trace minerals added to poultry diets at lower levels than inorganic trace minerals are more efficient than inorganic trace minerals and they provide some advantages in poultry nutrition. One of the most important advantages is the reduction of mineral amount excreted in faces. In addition, the results of researches conducted especially in the last few years have shown that the chelated forms of trace minerals strengthen the poultry immune system, and increase the use of other nutrients. However, there are inconsistent between the effects of different forms of trace minerals used in poultry diets on the performance.

Full textAbstract:
The ability of wheat bran and oat hulls to bind copper and zinc using a new chromatographic technique was investigated and compared to a centrifugation method. Also investigated was the bioavailability of copper which had been exogenously bound to wheat bran then fed to mice and rats. Wheat bran bound 6 mg Cu/g fiber when pH was raised to 7. Less binding occurred at lower pHs. Seven mg of zinc bound to wheat bran at pH 5 while only a trace bound at pH less than 2. Oat hulls bound 3 mg Cu/g fiber at pH 5, and less than 1 mg of zinc bound per g of oat hull at pH 6. Binding for both fibers depended on the level of mineral added to the fiber slurry during incubation. But only wheat bran binding capacity was influenced by pH. The two methods used did not compare favorably, in all cases, to the amount of mineral bound to fiber. Copper when bound to wheat bran, was utilized in both species, with differences occurring between species was noted. Rats fed the copper bound diet compared favorably with rats fed the copper-adequate diet as determined by body weight, weight gain, heart weight, liver copper concentration and heart copper concentration. Mice, on the other hand showed similar liver and heart concentrations of copper for mice fed either the copper-bound diet or the copper-adequate diets. The in vitro results showed that binding of copper or zinc to wheat bran occurred at a pH similar to the intestinal pH and wheat bran binds more copper and zinc than oat hulls. Oat hulls may prove to be a better dietary fiber source for those people who need to increase their dietary fiber, because oat hulls do not appear to bind copper or zinc and would not likely impair their absorption. Although wheat bran had a high binding capacity for copper, this binding did not significantly inhibit copper absorption as determined in animal studies suggesting that fiber-mineral binding (at least for copper bound to wheat bran) does not cause mineral deficiency symptoms as claimed by many researchers.

Mineral binding capacity of rice bran, oat hull, soy bran, wheat bran, peanut, apple, tomato, and barley fiber were investigated. Defatted fibers were analyzed for ash, protein, acid detergent fiber, and lignin. The fibers were washed with 1% HCl and Acid washed samples were studied for their mineral binding ability. The minerals tested were zinc, copper, and magnesium. Analysis of acid washed samples showed that most of the original minerals had been stripped from the fiber. In most of the fibers studied, the order of binding was copper > zinc > magnesium. Among the eight fibers studied, oat hull and apple fiber had the lowest consistent binding capacity for the three minerals investigated. This in vitro binding study has been run to duplicate intestinal condition of pH 6.8.

Previous issue date: 2015<br>Resumo: Introdução O desenvolvimento da nutrição parenteral (NP) na década de 1960 e sua subsequente utilização na prática clínica tem tido um enorme impacto sobre os pacientes com numerosas doenças para as quais a nutrição foi impossível por outra via. Mas, esta nova tecnologia tem riscos associados, incluindo o desenvolvimento de distúrbios metabólicos, superalimentação e complicações infecciosas. Método Foram realizados dois estudos. O primeiro estudo teve como objetivo avaliar, em uma coorte histórica de pacientes pediátricos no Brasil que receberam NP individualizada e exclusiva, a prevalência de hipofosfatemia, hipocalemia e hipomagnesemia em até 48 horas antes do início da infusão de NP (P1), do 1° ao 4° dia (P2); 5° ao 7° dia (P3) e, investigar se a infusão de caloria e proteína e também a desnutrição foram relacionadas com esses distúrbios. O segundo estudo foi feito no Canadá. Trata-se de um estudo retrospectivo e multicêntrico, avaliando pacientes sob nutrição parenteral domiciliar (NPD), prospectivamente inseridos no Home Parenteral Nutrition Registry (HPN Registry) nos períodos: 2005-2008 ou 2011-2014. Mudanças na demografia, indicações para NPD, prescrição, avaliação nutricional, acesso vascular e número de infecção de cateter por 1000 dias de cateter foram avaliados. Resultados A desnutrição esteve presente em 32,8% dos 119 pacientes avaliados no primeiro estudo, 66,4% estavam em unidade de terapia intensiva pediátrica (UTI Ped), 13,5% morreram. O período de maior prevalência de distúrbios minerais foi o P1 54 (45,3%), no P2 = 35 (31,8%), no P3 = 4 (3,57%). Hipocalemia esteve relacionada à desnutrição OR 2,79 (95% CI 1,09-7,14) p = 0,045. Nos primeiros sete dias, foram infundidas calorias inferior à quantidade recomendada pelas recomendações atuais em até 84,9% dos pacientes e proteína adequada em até 75,7%. Proteína infundida acima da recomendação nos primeiros quatro dias foi relacionada com hypomagnesaemia OR: 5,66 (IC 95% 1,24 - 25,79) p = 0,033. No estudo canadense, comparando os períodos 2011-2014 com 2005-2008, as indicações para a NPD mudaram significativamente com o aumento da proporção de pacientes com câncer (37,9% versus 16,7%) e diminuição da síndrome do intestino curto (32% versus 65,5%). A taxa de infecção de cateter diminuiu de 1,58 para 0,97 por 1.000 dias de cateter; o uso de cateter tunelizado diminuiu de 64,3% para 38,0% e a proporção de cateteres centrais de inserção periférica (PICC) aumentou de 21,6% para 52,9%. Além disso, houve uma redução no número e dias de internações relacionadas à NPD, e mudanças na prescrição de energia, proteína e oligoelementos. Conclusão Hipofosfatemia, hipocalemia e hipomagnesemia foram eventos frequentes, sendo a individualização ferramenta primordial para gerenciá-los. Pacientes desnutridos tiveram maior chance de desenvolver hipocalemia e os que receberam proteína acima da recomendação tiveram mais chances de desenvolver hipomagnesemia. Os resultados sugerem uma mudança no perfil demográfico e acesso venoso no Canadá, com melhora na infecção de cateter, hospitalizações relacionadas à NPD, e prescrições<br>Abstract: Introduction: The development of parenteral nutrition (PN) in the 1960s and its subsequent use in clinical practice has had a huge impact on patients with numerous diseases for which nutrition was impossible by other route. But, this new technology has associated risks, including the development of metabolic disorders, overfeeding, and infectious complications. Methods We conducted two studies The first study aims to evaluate in a historical cohort of pediatric patients, the prevalence of hypophosphatemia, hypokalemia and hypomagnesaemia until 48th hours before beginning PN infusion (P1), from 1st¿4th day (P2); 5th¿7th day (P3) of PN infusion and, investigate if malnutrition, calories, and proteins infusion were correlated to these disorders. In Canada, a retrospective study evaluating patients who were prospectively entered in the registry either in 2005¿2008 or in 2011¿2014 was done. Changes in patient demography, indications for Home Parenteral Nutricion (HPN), regimen, nutritional assessment, vascular access, and number of line sepsis per 1000 catheter days were evaluated. Results Malnutrition was present 32.8% of 119 patients participants from the first study, 66.4% were in pediatric intensive care unit (PICU), 13.5% died. The P1 was the period of highest prevalence mineral disorders 54 (45.3%), P2 had 35 (31.8%) and, P3=4 (3.57%). Hypokalemia events were related to malnutrition OR 2.79 (95% CI 1.09-7.14) p = 0.045. In the first seven days, infused calories were below the amount recommended by current guidelines in up to 84.9% of patients and protein infused was adequate in up to 75.7%. Protein infused above recommendation was related to hypomagnesaemia OR: 5,66 (95% CI 1,24 ¿ 25,79) p=0,033. In 2011¿2014 compared with 2005¿2008, indications for HPN changed significantly with an increased proportion of patients with cancer (37.9% versus 16.7%) and decreased short bowel syndrome (32% versus 65.5%). The line sepsis rate decreased from 1.58 to 0.97 per 1,000 catheter days; tunnelled catheters decreased as the most frequently chosen vascular access method from 64.3% to 38.0% and the proportion of peripherally inserted central catheters (PICC) increased from 21.6% to 52.9%. In addition, there was a reduction in number, and days of hospitalizations related to HPN, and changes in the prescription of energy, proteins, and trace elements were noted. Conclusion Hypophosphatemia, hypokalemia and hypomagnesemia were frequent events, being individualization primary tool to manage them. Malnourished patients were more likely to develop hypokalemia, and patients receiving protein above the recommendation were more likely to develop hypomagnesemia. Results suggest a shift in patient demography and line access in Canada, with improvement in line sepsis, hospitalizations and HPN prescriptions<br>Doutorado<br>Saude da Criança e do Adolescente<br>Doutora em Ciências

O estudo avaliou o efeito do treinamento no estado de nutrição em magnésio, ferro, zinco e cobre em atletas de paio aquático feminino pertencentes à Seleção Brasileira, considerando as concentrações de magnésio eritrocitário (Mg2+Er) e sérico (Mg2+S); zinco eritrocitário (Zn2+Er) e sérico (Zn2+S); a atividade da superóxido dismutase (CulZn-SOD) e a concentração de cobre sérico (CU2+S); hemoglobina (Hb), ferritina sérica (FER) e porcentagem de saturação da transferrina (%ST) em períodos pré-competitivo, de destreino e de manutenção. Foi também avaliada a ingestão desses minerais, considerando as novas DRls, que foi associada aos parâmetros bioquímicos do pré-competitivo e comparada a um grupo de controles. Em atletas houve consumo de Mg2+ com maior probabilidade de inadequação e a concentração do Mg2+S mostrou tendência a valores menores, comparadas às controles. O consumo dietético de Zn2+ foi maior para as atletas (p<O,05), entretanto, a sua concentração média de Zn2+Er foi menor (p<O,05). O consumo de ferro não foi diferente entre os dois grupos estudados, porém, o estado nutricional (EN) em ferro foi significantemente maior em atletas. Ambos os grupos apresentaram estado de nutrição em cobre adequado. A atividade da CuIZn-SOD foi maior para atletas (p<O,05) e o CU2+S, sem diferença entre os grupos, foi o parâmetro que melhor associou-se à ingestão dietética. O treinamento pré-competitivo alterou significantemente o estado de nutrição em cobre e em ferro (p<O,05). Possivelmente, o treinamento intenso promoveu redistribuição comparti mental de Zn2+ a partir do eritrócito.

The intakes of these minerals were also evaluated, considering the new DRIs, which were associated to the biochemical parameters of the pre-competitive, and compared to a control group. Athletes presented a magnesium intake with greater probability of not being adequate and the SMg2+ concentration showed a tendency to lower values, compared to controls. The dietary Zn2+ intake was greater for athletes (p<0.05); however, their mean ErZn2+ concentration was lower (p<0.05). The iron intake was not different between the two studied groups; however, the iron nutrition status was significantly better in athletes. Both groups presented adequate copper nutritional status. The Cu/Zn-SOD activity was greater for athletes (p<0.05) and the SCu2+, with no difference between groups, was the parameter, which was better associated to the dietary intake. The pre-competitive training altered copper and iron nutritional status significantly (p<0.05). Possibly, the intense training promoted the compartmental redistribution of Zn2+ as from the erythrocyte. The training did not alter the Mg2+ nutritional status; however, homeostatic physiologic mechanisms may have occurred, nevertheless not avoiding the occurrence of cramps after intense training. ErZn2+ was recovered in the detraining.

Full textAbstract:
The effect of three sources of protein: soy, dairy, and meat protein, and two levels of calcium on zinc, iron, copper, calcium, and magnesium retention in young adult men was determined in a 30-day metabolic balance study. The study was divided into a twenty-day baseline period, a thirty day controlled feeding period from which all the balance data was collected, and a twenty day follow-up period. During the controlled feeding period, twenty-four subjects were randomly assigned to one of three dietary treatment groups which differed in respect to protein source. The dairy treatment group was fed a diet in which 70% of the dietary protein was derived from dairy products; the soy treatment group was fed a diet in which 67% of the dietary protein was derived from soy products; and the meat treatment group was given a diet in which 70% of the dietary protein was provided by animal meat products. To test the effect of calcium level on mineral retention, the controlled feeding period was divided into two periods: Period I, in which the subjects consumed moderate levels of calcium (mean= 1206.77 + 193.29 mg/day) and Period II, in which the subjects consumed high levels of calcium (mean 2134.51 + 164.63 mg/day).<br>Master of Science

Previous issue date: 2018-02-20<br>Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)<br>O selênio (Se) é um micronutriente essencial aos seres humanos e animais, entretanto verifica-se frequentemente alimentos pobres neste micronutriente, fato este, explicado principalmente pelo seu baixo teor nos solos. Uma dieta deficiente neste mineral resulta na maior suscetibilidade a uma série de doenças, dentre elas câncer, hipertireoidismo e doenças cardíacas. Nesse contexto, a biofortificação de alimentos é uma alternativa promissora para a inserção do Se na alimentação humana. Assim, objetivou-se avaliar o efeito de doses de Se no crescimento, produção e biofortificação da rúcula. Plantas de rúcula foram cultivadas em ambiente protegido no sistema hidropônico. Foram avaliadas sete concentrações de Se (0, 10, 20, 30, 40, 50 e 60 µmol L-1), utilizando-se o selenato de sódio como fonte de Se. O número de folhas, área foliar, altura, massa fresca e seca da parte aérea, massa seca da raiz e produtividade foram influenciados pelas concentrações de Se. Os melhores resultados foram obtidos entre as concentrações 20 a 29 µmol L-1 de Se. Os teores de enxofre (S) e potássio (K) aumentaram linearmente com incremento no fornecimento de Se. Constatou-se a biofortificação agronômica da rúcula, pois o aumento da concentração de Se na solução nutritiva resultou em aumento no teor deste elemento na planta. Os tratamentos com o fornecimento de Se na solução nutritiva proporcionaram rúculas com teores que variaram de 598,96 a 1437,56 µg kg-1 de Se, em relação às plantas cultivadas em solução nutritiva sem Se que apresentaram 167,84 µg kg-1 de Se.<br>Selenium (Se) is an essential micronutrient for humans and animals. However, food often presents low content of this micronutrient, which is resulted mainly due to the low content of Se in the soil. The insufficient consumption of this mineral can increase the susceptibility to several diseases, including cancer, hyperthyroidism and heart disease. In this context, the biofortification of food is a promising alternative for Se insertion into the human diet. The objective of this study was to evaluate the effect of Se doses on the growth, production, and biofortification of rocket plants. Rocket plants were grown in a protected environment in the hydroponic system. Seven concentrations of Se (0,10, 20, 30, 40, 50 and 60 μmol L-1) were evaluated. Sodium selenate was used as a source of Se. The number of leaves, leaf area, height, fresh and dry shoot mass, root dry mass and productivity were influenced by the concentrations of Se. The best results were obtained between the concentrations 20 to 29 μmol L-1 of Se. With the supply of Se was possibly observed a linear increase in the sulfur (S) and potassium (K) contents. Agronomic biofortification of rocket plants was verified since the increase of the Se concentration in the nutritive solution resulted in an increase in the content of this element in the plant. Treatments with the supply of Se in the nutrient solution provided rocket plants ranging from 598.96 to 1437.56 μg kg-1 of Se, in relation to plants grown in nutrient solution without Se that presented 167,84 μg kg-1 Se.

Background: Insects, particularly the black soldier fly (Hermetia illucens), have gained attention as a promising alternative protein source to address food security challenges. This study explores the potential of black soldier fly larvae as a sustainable and nutritious protein source for human consumption. Objective: The objective of this study is to investigate the nutritional composition and safety aspects of black soldier fly larvae, evaluate its potential as a viable protein source, and discuss its implications for food security and policy. Methods: Black soldier fly larvae were reared under controlled conditions and analyzed for their nutritional composition, including protein content, amino acid profile, fatty acid profile, and micronutrient content. Safety aspects, such as heavy metal and pesticide residue levels, were also assessed. The study further examined the feasibility and scalability of black soldier fly production for human consumption. Results: The results reveal that black soldier fly larvae possess a high protein content, rich in essential amino acids, and a favorable fatty acid profile. Furthermore, the larvae contain significant amounts of essential micronutrients, including vitamins and minerals, contributing to a well-rounded nutritional profile. Safety analysis demonstrates low levels of heavy metals and pesticide residues, indicating its suitability for human consumption. The study also identifies the potential of large-scale black soldier fly production as an economically viable solution for food security. Conclusion: This study highlights the potential of black soldier fly larvae as a sustainable and nutritious protein source for human consumption. With its high protein content, favorable nutrient profile, and safety parameters, black soldier fly larvae offer a promising solution to address food security challenges. Incorporating black soldier fly larvae into diets and food systems has the potential to enhance nutritional adequacy and reduce reliance on traditional protein sources. Furthermore, the findings emphasize the need for policy frameworks and regulatory support to promote the adoption of insect-based diets and ensure their safe integration into global food systems. Keywords: Black soldier fly, Hermetia illucens, insect-based diet, food security, protein source, sustainability, nutritional composition, safety.

Introduction: There is a lack in the awareness in the fruit and vegetable (F&V) recommendation among Saudi society. Although the known facts of the benefits of F&V on health, information on Saudi society following the advised recommendation whether by WHO or local is still unknown. Aim: This cross- sectional study aim to examine the perception of F&V intake among students and staff at Umm Al-Qura University and to assess if they follow these recommendations of F&V locally and internationally. Method: Students and staff from Umm Al-Qura University participated in this study (n= 98, age between 18- 55). All data were collected using short online survey via Online survey - Survey Monkey in 2019. Result: 55% students and staff were not aware about these recommendations whereas 45% were aware about WHO recommendation. The majority of students and staff 53% have less than two portions a day of F&V. Only 14% have between two to four portions a day. 32% do not eat any portion of F&V daily. 59%, 14%, 5% of students and staff who believe that they should have five, seven, more than seven portions a day for being healthy respectively. Maintaining health, reduce the risk for chronic disease and providing essential vitamins and minerals to the body were all reasons why students and staff believe that they should have F&V everyday by 71%. Busy lifestyle, F&V cost, lack of the awareness about the health benefits, dislike the taste, some F&V spoil easily were all factors affecting eating F&V daily. Conclusion: People need educational and nutritional campaigns to spread the awareness about the health benefits of F&V. Most importantly the ministry of health should support those campaigns to increase people awareness and build a healthy society with a good habit. Keywords: Fruit intake, veg intake, F&V recommendation, students, staff, Umm Al-Qura University

Full textAbstract:
Consumers are increasingly demanding choices of ready-made foods with excellent organoleptic and health-related properties. There are two main trends in Europe; firstly, consumers are increasingly choosing foods that are comfortable for use, secondly, the number of people who are overweight is increasing, with more consumers paying close attention to the ingredients and nutritional value of products in order to balance the amount of the food they consume per day. The aim of the research was to develop new potato main courses and to determine their nutritional value. The research was carried out at the Faculty of Food Technology of the Latvia University of Agriculture, Institute of Food Safety, Animal Health and Environment "BIOR" and Laboratory of Mineral Nutrition at the Institute of Biology of the University of Latvia. Four different potato main course types with amaranth, quinoa, bulgur and chicken were prepared for the study; plain potatoes were used as the control sample. The content of protein, carbohydrates, lipids, fibre and minerals (N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, Mo, B) was determined in all potato main course samples. The addition of amaranth, quinoa and bulgur significantly increased the content of dietary fibre, protein, carbohydrates and lipids (p&amp;amp;lt;0.05), whereas the addition of chicken fillet significantly increased protein and lipid content, but reduced the content of carbohydrates and dietary fibre. The content of various minerals, which are an indispensable part of the diet as they are necessary for the body's life processes and normal development, was significantly increased by the addition of chicken to the potato main course. The highest dietary fibre content was detected in potato main course with amaranth (3.0 g per 100 g product), drawing up to 9.0 g dietary fibre per one serving (300 g). Following the Regulation (EC) No 1924/2006, potatoes with amaranth can be defined as the “source of fibre”.

To initiate the process of soil formation, it is necessary to introduce a culture of microorganisms capable of improving mineral nutrition, plant growth and resistance to adverse factors, regardless of the mineralogical composition of the surface. The advantage of the developed methods is the multifunctionality of the sorbent, which is an abiotic catalyst: the dangerous agent binds physically due to the formed fine-porous structure, and chemically due to the ion exchange processes occurring due to the nature of the layered glauconite silicate. The viability of immobilized glauconite bacterial cells of Agrobacterium radiobacter 204, Rhizobium leguminosarumbiovartrifolii, Flaviobacterium L 30 fulvum, Pseudomonas aureofaciens 1393 BS, amounted to no less than 4 months., while the original biological products are stored no more than 1 month.

Full textAbstract:
Lettuce is one of the most popular leafy vegetables due to the high concentrations of minerals and vitamins. The high ecological plasticity and short vegetation period makes it extremely vulnerable to environmental conditions and, indirectly, to climate change. In order to obtain plants with valuable nutritional profile, the environmental conditions for cultivation, like moisture content and temperature are very important. There are many research studies performed concerning the effects of climatic changes on agricultural production, but the impact on the nutritional value of foods has not been commonly studied. The question to which this study intends to answer is to present the influence of climate change on mineral content of lettuce based on database information and experimental data, using different mathematical models. Even if lettuce production is performed mostly under controlled conditions, there are important modifications regarding nutritional profiles of lettuce, in special minerals content.

Full textAbstract:
Dairy products are of particular importance for human nutrition. They provide about 100 nutrients (26 fatty acids, 45 minerals and 25 vitamins). Especially, fermented cream is among the most important dairy product that has a major demand on the consumer market, being purchased daily by consumers. Cream is high in fat. Cream fats are easily assimilated by the human body. The purpose of this paper is to determine the conformity of fermented cream and the study of standardized indices. The following research methods were included: method of analysis, methods of scientific knowledge and expertise. The paper contains the results of organoleptic, physico-chemical and sensory research on the quality of local and imported cream products. The results of the research show that no product fully met the prescribed requirements. We also studied consumer preferences by sensory analysis of fermented cream (20 points). The highest score was 18.4 points, accumulated by the "President" cream. In addition, we checked the correctness of the mandatory information on the product labels. In this sense, out of all the 6 products analyzed, only one product meets the requirements of Law 279 on consumer information on food. The other products are missing one or two pieces of information related to the batch number, product safety information and the label with the translation into the state language.

Full textAbstract:
PGPR bacteria include taxonomically diverse bacterial species that function for improving plant mineral nutrition, stress tolerance, and disease suppression. A number of PGPR are being developed and commercialized as soil and seed inoculants, but to date, their interactions with resident bacterial populations are still poorly understood, and-almost nothing is known about the effects of soil management practices on their population size and activities. To this end, the original objectives of this research project were: 1) To examine microbial community interactions with plant-growth-promoting rhizobacteria (PGPR) and their plant hosts. 2) To explore the factors that affect PGPR population size and activity on plant root surfaces. In our original proposal, we initially prqposed the use oflow-resolution methods mainly involving the use of PCR-DGGE and PLFA profiles of community structure. However, early in the project we recognized that the methods for studying soil microbial communities were undergoing an exponential leap forward to much more high resolution methods using high-throughput sequencing. The application of these methods for studies on rhizosphere ecology thus became a central theme in these research project. Other related research by the US team focused on identifying PGPR bacterial strains and examining their effective population si~es that are required to enhance plant growth and on developing a simulation model that examines the process of root colonization. As summarized in the following report, we characterized the rhizosphere microbiome of four host plant species to determine the impact of the host (host signature effect) on resident versus active communities. Results of our studies showed a distinct plant host specific signature among wheat, maize, tomato and cucumber, based on the following three parameters: (I) each plant promoted the activity of a unique suite of soil bacterial populations; (2) significant variations were observed in the number and the degree of dominance of active populations; and (3)the level of contribution of active (rRNA-based) populations to the resident (DNA-based) community profiles. In the rhizoplane of all four plants a significant reduction of diversity was observed, relative to the bulk soil. Moreover, an increase in DNA-RNA correspondence indicated higher representation of active bacterial populations in the residing rhizoplane community. This research demonstrates that the host plant determines the bacterial community composition in its immediate vicinity, especially with respect to the active populations. Based on the studies from the US team, we suggest that the effective population size PGPR should be maintained at approximately 105 cells per gram of rhizosphere soil in the zone of elongation to obtain plant growth promotion effects, but emphasize that it is critical to also consider differences in the activity based on DNA-RNA correspondence. The results ofthis research provide fundamental new insight into the composition ofthe bacterial communities associated with plant roots, and the factors that affect their abundance and activity on root surfaces. Virtually all PGPR are multifunctional and may be expected to have diverse levels of activity with respect to production of plant growth hormones (regulation of root growth and architecture), suppression of stress ethylene (increased tolerance to drought and salinity), production of siderophores and antibiotics (disease suppression), and solubilization of phosphorus. The application of transcriptome methods pioneered in our research will ultimately lead to better understanding of how management practices such as use of compost and soil inoculants can be used to improve plant yields, stress tolerance, and disease resistance. As we look to the future, the use of metagenomic techniques combined with quantitative methods including microarrays, and quantitative peR methods that target specific genes should allow us to better classify, monitor, and manage the plant rhizosphere to improve crop yields in agricultural ecosystems. In addition, expression of several genes in rhizospheres of both cucumber and whet roots were identified, including mostly housekeeping genes. Denitrification, chemotaxis and motility genes were preferentially expressed in wheat while in cucumber roots bacterial genes involved in catalase, a large set of polysaccharide degradation and assimilatory sulfate reduction genes were preferentially expressed.

Focusing on Multiple Micronutrient Supplements in Pregnancy: Second Edition. Sight and Life, 2011. http://dx.doi.org/10.52439/uznq4230.
Full textAbstract:
Despite marked progress in improving nutrition and health globally, micronutrient deficiencies remain prevalent in low and middle income countries (LMIC), especially among pregnant women with far-reaching consequences for mother and baby including preterm birth, stillbirth or neonatal death, impaired fetal growth. Multiple micronutrient supplements (MMS) taken during pregnancy provide 15 vitamins and minerals to fill the dietary gaps often present in LMIC and the increased nutrient needs of pregnancy. Crucially, MMS provide benefits far beyond those of traditional iron and folic acid supplements (IFA) – prompting the World Health Organization to add the UNIMMAP (United Nations International Multiple Micronutrient Antenatal Preparation) MMS formulation to its Essential Medicines List (EML) in 2021. The Sight and Life Special Report, Focusing on Multiple Micronutrient Supplements in Pregnancy: Second Edition puts forth a compelling case that maintaining the status quo of IFA supplementation is no longer possible when so many stand to benefit from MMS, and demonstrates the benefits and process of switching to MMS. The report compiles the latest evidence, country case studies, and resources in a single place to support implementers and country governments in introducing and scaling-up MMS.
