Resumen
Культура питания - важнейший компонент здорового образа жизни. Вступивший в силу 1 мая 2020 года Федеральный закон «О внесении изменений в Федеральный закон «О качестве и безопасности пищевых продуктов» и ст. 37 Федерального закона «Об образовании в Российской Федерации» закрепляет понятие «здоровое питание» и его принципы. Здоровое питание - питание, ежедневный рацион которого основывается на принципах, установленных Федеральным законом, отвечает требованиям безопасности и создает условия для физического и интеллектуального развития, жизнедеятельности человека и будущих поколений. Чтобы рационально питаться, нужно иметь представление о составе продуктов, их биологической ценности и преобразовании питательных веществ в организме. Правильное питание, забота о здоровье невозможны без знаний о пищевой ценности продуктов. Пищевая ценность пищевых продуктов - потребительское свойство пищевых продуктов, характеризующее наличие и количество необходимых для удовлетворения физиологических потребностей человека составляющих их пищевых веществ (нутриентов) и энергетическую ценность. Полноценная еда должна учитывать не только содержание питательных веществ, но и нормы их суточного потребления. В настоящее время появляются новые данные, корректирующие нормы физиологических потребностей в энергии и пищевых веществах, что является естественным развитием науки о питании. Одним из важнейших факторов, способствующих здоровому питанию, правильному выбору пищевых продуктов потребителями, является маркировка пищевых продуктов. В соответствии с современными тенденциями маркировка пищевой продукции для здорового питания должна включать информацию о пищевой ценности в обязательном порядке, и информацию об эффективности (пользе для здоровья). Food culture is the most important component of a healthy lifestyle. The Federal Law «On Amendments to the Federal Law» «On the Quality and Safety of Food Products» and Article 37 of the Federal Law» «On Education in the Russian Federation», which entered into force on May 1, 2020, establishes the concept of «healthy food» and its principles. Healthy food - food, the daily diet of which is based on the principles established by Federal law, meets the safety requirements and creates conditions for physical and intellectual development, human life and future generations. To eat rationally, you need to have an understanding of the composition of products, their biological value and the transformation of nutrients in the body. Proper nutrition, health care is impossible without knowledge about the nutritional value of products. The nutritional value of food products is a consumer property of food products that characterizes the presence and quantity of their constituent nutrients (nutrients) and energy value necessary to meet the physiological needs of a person. A full meal should take into account not only the content of nutrients, but also the norms of their daily consumption. Currently, new data are emerging that adjust the norms of physiological energy and nutritional needs, which is a natural development of nutrition science. One of the most important factors contributing to a healthy diet, the correct choice of food products by consumers, is the labeling of food products. In accordance with current trends, the labeling of food products for a healthy diet should include information about the nutritional value without fail, and information about the effectiveness (health benefits).

Resumen
Nutritional well-being is a sustainable force for health and development of people and maximization of human genetic potential. From the beginning of human history, food has been considered as the major factor in maintaining well-being and health of individuals. Active ingredients in food which are effective in promoting human health include amino acids, fats dietary fiber, antioxidants, pigments, vitamins and minerals which are present in different food groups such as pulses, cereals, legumes, oilseeds, fruits and vegetables. Among all these food groups, fruits and vegetables play a significant role in human nutrition, especially as a source of vitamins, minerals and dietary fiber. The different fruits and vegetables like carrots, tomatoes potatoes, ginger, green leafy vegetables and the like are important protective foods because of their nutritional value and antioxidant properties. Value addition of such fruits and vegetables by formulation of different value-added products are an important source of nutritional security.

Resumen
Background: The preconception period is a crucial period to optimize maternal and fetal health. Preconception nutrition can affect nutritional status and mental health which has an impact on pregnancy readiness. This study aims to analyze the correlation between nutrition and nutritional status and mental health during the preconception period. Method: This study used a prospective cohort study involving women of childbearing age selected by stratified random sampling to obtain 129 respondents. Nutritional Style data were collected through FFQ questionnaires, nutritional status was measured through anthropometry and Hemoglobin examination, and mental health was measured using the DASS questionnaire. Data collection was carried out three times and analyzed using the Pearson correlation test, multiple linear regression and the Wilcoxon test for longitudinal analysis. Result: The results showed that there was no significant correlation between Nutritional Style and BMI (p-value>0.05). However, there was a significant correlation between Nutritional Style and the incidence of anemia, the strongest correlation in the first measurement (p-value 0.001) and the second measurement (p-value 0.049). A significant correlation was found between Nutritional Style and mental health, especially anxiety in the first measurement (p-value 0.022), the second measurement (p-value 0.006) and the third measurement (p-value 0.029), but not with stress and depression. There was a significant increase in nutritional status from the first to the second measurement (p-value 0.020) and the first to the third measurement (p-value 0.003). There was a significant decrease in anxiety from the first to the second measurement (p-value 0.034) and the first to the third measurement (p-value 0.000). Conclusion : Good Nutritional Style during preconception can improve nutritional status and minimize mental health risk. Nutrition intervention programs are needed to improve knowledge and implementation of healthy food nutrition. In addition, regular monitoring of nutritional status and mental health is also needed to optimize pregnancy readiness.

Resumen
Caryota urens which is commonly known as Kithul, is a multipurpose and underutilized palm mainly distributed in Asia. Due to its numerous applications, it has been considered an important plant that ensures the livelihood of the village people in Sri Lanka. Thus, this article reviews the nutritional and medicinal values of kithul palm and its value-added products. Kithul sap is widely used in the production of kithul treacle and jaggery due to its high amount of sugar content. Kithul seed oil is high in palmitic and oleic acid and is a good source of biofuels. Kithul fruit has skin-irritating nature due to the presence of oxalic acid, and also it contains anti-nutritional substances such as phytate, tannin and saponin. Different parts of Kithul palm such as leaves, flowers, fruit, sap is rich in antioxidants, anti -inflammatory, antimicrobial, and anti-diabetic properties due to the existence of flavonoids, glycosides like phytochemicals. Low gelatinization temperature has identified Kithul flour as a good gelling agent, stabilizer and thickener. Owning to its low Glycemic Index, kithul flour has become beneficial for people suffering from diabetics. Thus, valueadded products like biscuits, noodles, bread, muffin, rotti, porridge, dessert, yoghurt are identified as potential products that must be commercialized with more investigations.

Resumen
SUMMARYYogurt, made from fortified skim milk by conventional methods using Streptococcus thermophilus and Lactobacillus bulgaricus, was used in studies of the effect of fermentation on nutritional value of milk. In all experiments, the product was compared with the uninoculated base milk. The concentration of most vitamins was less in yogurt than in milk and was most noticeably so for biotin which was 60% less. The effect on folic acid content was inconsistent. In nutritional experiments with rats, high values for true digestibility, biological value and net protein utilization were obtained for both yogurt and its base milk, only minor differences being apparent between the two materials. In growth tests with rats, yogurt was not found to be consistently superior to the base milk when the milk was subjected to a double heat treatment to reduce bacterial contamination. Yogurt did not confer a nutritional advantage on fresh milk in this respect.

Resumen
Chapati, an unleavened flat bread, is a staple in the diet in Pakistan. Wheat in the form of chapati can contribute as much as 90% of the total dietary energy intake to the rural population and generally provides more than half dietary energy and protein. Such a heavy dependence on this cereal food has led to protein malnutrition due to wheat proteins being deficient in lysine, an essential amino acid. The aim of this study was to produce savoury chapati with enhanced nutritional value. Attitudes to a variety of savoury flavours were determined in consumers of Pakistan and in immigrants to Glasgow. Chicken and meaty were most and cheesy least preferred. Amongst chapati quality characters, nutritional value was rated highest followed by flavour. These studies suggested that consumers favoured a product with appropriate flavour, a soft texture and of high nutritional value. Typically chapaties are prepared with wholemeal flours with medium rheological optima. Doughs of British wheat varieties Fresco and Galahad (33+67) and Mercia and Galahad (50+50) had moderate stickiness, high sheeting ability, and were low in shrinkage after sheeting. Such suitable mixtures yielded flours suitable for chapati production. Wheat protein profiles were determined by electrophoresis and relationships between proteins and rheological properties determined with partial least squares regression (PLS2). Dough development time was positively correlated with aggregated values of high molecular weight (HMW) and low molecular weight (LMW) glutenins, ratio of polymeric to monomeric and LMW glutenins, and negatively correlated with the total of gliadin, globulin and albumin fractions. Dough stability showed negative and tolerance index positive correlations with gliadin. Resistance to extension was associated with dough stability and inversely with gliadin content. Such studies reveal that glutenin contributes strength and gliadin imparts weakness to flour. Response surface methodology, used to optimise chapa ties , revealed that a successful savoury product could be produced by incorporating 1.5 to 2.0 % yeast extract without any deleterious effect on dough physical characteristics. Yeast extract enhanced the concentrations of protein from 13.1 % to 14.4 % in chapati. In addition to enhanced nutritional value, yeast extract imparted a desirable savoury flavour to chapati.

Resumen
Mestrado em Ecologia Aplicada<br>A Teoria do Forrageio Ótimo propõe que o estímulo nutricional na escolha de presas e busca de alimento em carnívoros é o ganho energético. Em contraste, pesquisas recentes sugerem que os carnívoros selecionam presas que fornecem uma dieta com um equilíbrio específico de macronutrientes (gordura, proteína, hidratos de carbono), ao invés do maior conteúdo energético. Para este efeito, as escolhas de presas de lontras-marinhas (Enhydra lutris) que habitam Sitka Sound no sudeste do Alasca, foram estudadas durante os meses de maio a agosto de 2016. Os objetivos desta pesquisa foram: 1) descrever a dieta das lontras-marinhas em Sitka Sound; 2) descrever o valor nutricional das suas presas; 3) comparar diferenças na escolha de presas de acordo com o sexo; e 4) avaliar e comparar o valor nutricional das presas com as escolhas das lontras-marinhas. Os dados de observação foram coletados oportunisticamente, através de uma plataforma de oportunidade. As presas de lontras-marinhas foram capturadas em áreas arbitrárias de Sitka Sound, e analisadas quanto à sua percentagem em lípidos (teor de gordura) e calorias (densidade de energia). O consumo de presas foi significativamente diferente: as amêijoas foram as presas mais consumidas (68,6%), seguidos pelos ouriços-do-mar (14,3%), vieiras (5,7%), pepinos-do-mar (5,7%), caranguejos (2,9%) e estrelas-do-mar (2,9%). Além disso, os resultados revelaram uma significativa diversidade no conteúdo de gordura e densidade energética entre presas de lontra-marinha. O abalone registou maior teor de densidade energética, seguido pelas vieiras, enquanto que os ouriços-do-mar registaram maior teor em lípidos. A escolha de presas e a ingestão de nutrientes não diferiram significativamente entre machos e fêmeas, no entanto, os machos de lontras-marinhas consumiram mais moluscos do que as fêmeas, enquanto que as fêmeas consumiram mais ouriços-do-mar do que os machos. O trabalho sobre nutrição em carnívoros é preliminar, e estes resultados fornecem um ponto de partida para futuras pesquisas. As respostas a estas questões não só terão implicações significativas na gestão das populações de predadores e das comunidades ecológicas de que fazem parte, mas também acrescentarão informações importantes sobre a biologia de predadores que até agora foram negligenciadas. Além disso, os conflitos nas comunidades sobre os impactos que as lontras-marinhas têm na pesca comercial no sudeste do Alasca, não podem ser ignorados. Compreender as escolhas de presas de lontras-marinhas pode fornecer previsões de como a pesca pode ser afetada, de acordo com o crescimento da população de lontras nesta área, a fim de ajudar políticos, membros da comunidade e pescadores comerciais, a responder em conformidade.<br>Foraging theory proposes that the nutritional driver of prey choice and foraging in carnivores is energy gain. In contrast, recent research suggests that carnivores select prey that provides a diet with a specific balance of macronutrients (fat, protein, carbohydrates), rather than the highest energy content. To this effect, the prey choices of sea otters (Enhydra lutris) inhabiting Sitka Sound, in southeast Alaska, were studied during the months of May-August of 2016. The goals of this research were to 1) describe sea otter’s diet in Sitka Sound; 2) describe the nutritional value of sea otters’ prey items; 3) compare differences in prey choice according to sex; and 4) evaluate and compare prey’s nutritional value with sea otter’s prey choices. Foraging observational data were collected opportunistically on a boat-based platform of opportunity. Sea otter’s main prey were captured in arbitrary areas of Sitka Sound, and analyzed for percentage in lipids (fat content), and calories (energy density). Prey consumption was significantly different: clams were the most frequently consumed prey (68,6%), followed by sea urchins (14,3%), scallops (5,7%), sea cucumbers (5,7%), crabs (2,9%) and sea stars (2,9%). Also, the results revealed a significant diversity in content of fat and energy density between sea otter prey specimens. Abalone ranked first on content of energy density, followed by scallops, while sea urchins recorded the highest lipid content. Prey choice and nutrient intake were not significant different between male and female sea otters, nevertheless, males consumed more clams than females, while females consumed more sea urchins than males. The work on carnivore nutrition is preliminary, and these results provide a starting point for future work. Answers to such questions not only will have significant implications for managing predator populations and the ecological communities of which they are a part, but will also add important information on predator biology that has been neglected so far. Moreover, communities’ conflicts over the impacts sea otters are having on commercial shellfisheries in southeast Alaska cannot be overlooked. Understanding sea otter’s prey choices may provide information and predictions of how fisheries may be affected as the sea otter population grows in this area, in order to help decision makers, policy makers, community members, and commercial fishermen respond accordingly.

Resumen
This is the first study to investigate the nutritional requirements of the penaeid prawn protozoeal phase (the first feeding stage of the prawn life cycle) using micro algae to provide different nutritional conditions. The work was a simultaneous examination of the biochemical composition of the larvae and their microalgal diets. In addition, the influence of naupliar composition on later larval stages was studied. The biochemical parameters measured were total protein, lipid and carbohydrate (i.e. gross biochemical composition) and total lipid was further resolved into individual fatty acids. The nutritional requirements of penaeid prawn larvae were assessed by measuring the survival, development (metamorphosis) and growth (in terms of dry weight) of larvae in response to various algal diets. In this way differences in survival, development and growth could be related to biochemical differences in the algal diets and associated larval body composition. The changes in biochemical composition of *Penaeus japonicus* and *P. monodon* larvae during metamorphosis from nauplii to protozoea 1 (PZl) and the time course of these changes during starvation and feeding for the ~42 h period that the PZl stage lasts, were examined. The larvae utilised lipid as a major energy source during metamorphosis. The fatty acid fraction of the lipid in nauplii was high (60 to 80%) compared with protozoeae (30 to 60%) and provided a large proportion of the energy required for metamorphosis. Of the total fatty acids, the monounsaturated (MUFAs) and saturated fatty acids contributed most of this energy. During starvation the MUFAs and polyunsaturated fatty acids (PUPAs) were metabolised while the highly unsaturated fatty acids (HUFAs) were conserved, presumably because of their role as structural components in cell membranes. The PUFA linoleic acid (18:2n-6) appeared to have a role as a component of cell membranes when in short supply, but it accumulated as an energy reserve when in excess in the diet. Linolenic acid (18:3n-3) was actively metabolised to other membrane fatty acids or used for energy. The effect of altering the biochemical composition of the microalga *Tetraselmis suecica* on *P. semisulcatus* larvae was studied by reducing the nitrate concentration from -1760 μ*M* to 176 μ*M* in the culture media. Carbohydrate increased three fold in the low nitrate algae, and protein and lipid were reduced slightly compared to the control. The low protein:energy ratio (0.1 to 0.2) of the low nitrate diets resulted in a delay in the development of the larvae compared to that of the animals fed the control diet (ratio 0.3 to 0.4). Survival was not affected by the algal diets. Four species of algae (*Tetraselmis suecica*, *Chaetoceros muelleri*, Tahitian *Isochrysis* sp. (T-iso) and *Dunaliella tertiolecta*) differing predominantly in their fatty acid composition were fed to *P. japonicas* larvae as single species diets. The two best diets (in terms of growth and survival of the prawn larvae) were subsequently fed in combination to *P. semisulcatus* and *P. monodon* larvae to assess their nutritional value as part of a mixed diet. The survival and development to mysis 1 (M1), i.e. performance, of the larvae was affected by the algal diets such that the diets could be ranked: *C. muelleri* > *T. suecica* > *Isochrysis* sp. (T-iso) > *D. tertiolecta*. The fatty acid profiles of the algae, particularly those of arachidonic acid (20:4n-6) and eicosapentaenoic acid (20:5n-6), were related to those of the larvae and their performance. The presence of both of these fatty acids in the algal diet was necessary to produce high performance whereas docosahexaenoic acid (22:6n-3) was not. The low requirements for the PUPAs 18:2n-6 and 18:3n-3 were modulated by the presence of HUFAs such as 20:4n-6, 20:5n-6 and 22:6n-3. Therefore when these HUFAs were present in the diet, less 18:2n-6 and 18:3n-3 were required. However high proportions of 18:2n-6 and 18:3n-3 alone, did not replace the requirements for 20:4n-6, 20:5n-6 and 22:6n-3. Understanding the nutritional requirements of penaeid prawn larvae will lead to the production of a cost effective and optimum diet for use in hatcheries. In addition, this research will contribute to the production of a purified artificial diet for penaeid prawn larvae which can be used to examine the requirements for other nutrients.

Resumen
Cocoyam [Colocasia esculenta (L.) Schott] is widely cultivated as a staple food in the tropical and subtropical regions of the world. The crop, however, remains unpopular and not well known outside KwaZulu-Natal Province of South Africa where it is cultivated mainly for subsistence. The aims of the study were to collect local landraces (accessions) of the crop from where it is found growing within the country for various studies and also to document its nutritional values as well as the safety/toxicity of the crop. The study was carried out using various methods. These included a comparative assessment of the proximate, mineral and antinutrient compositions of cooked and uncooked tubers of a typical commercially available cocoyam and potato found in South African markets. These investigations were repeated for the tubers and leaves of available landraces (seven accessions) of C. esculenta found growing in the farmers’ fields in KwaZulu-Natal Province. Also, an in vivo toxicological study on cooked accessions of the local landraces was conducted to determine possible toxicity effects after consumption using albino rats as a model. The results revealed that commercially available cocoyam and potato tubers have very close nutritional components. Analysis of the proximate composition of seven accessions (UFCe1- UFCe7) of cooked and uncooked tubers of cocoyam indicated that UFCe7 was better in ash, crude protein, crude fibre and crude lipid contents but with higher moisture which could make it more vulnerable to microbial attack. No tubers of the seven accessions appeared to be ii outstandingly better than the others based on their mineral compositions. However, in terms of antinutritional factors, UFCe1, UFCe3 and UFCe7 had the least amounts of oxalate, tannins and phytate in their cooked states. It was discovered however, that the leaves of the accessions of this vegetable contain substantial amount of minerals, and therefore, can contribute significantly to the nutrient requirements of humans and could be recommended as a cheap source of nutrients in South Africa. None of the accessions was outstandingly better than the others in terms of their mineral contents and anti-nutritional factors. Moreover, the current study has shown that boiling the leaves of cocoyam prior to consumption is an effective way of reducing the antinutrient contents of the leaves of the plant thereby making it safe for consumption. The findings also revealed that cooking C. esculenta leaves may increase the levels of protein, fibre and lipid contents while cooking may also decrease the mineral, carbohydrate and caloric contents of the leaves of the accessions. The leafy vegetable may, therefore, be recommended as a cheap source of plant protein. Cooking improved the nutritive value as a result of the reduction in antinutrient levels, thereby improving the food quality in all the tuber and leaf samples used for this study. At the same time, cooked samples also suffered loss of some nutrients with respect to the proximate and mineral compositions. However, supplementation from other food sources that are rich in these nutrients is necessary when these crops are cooked for consumption. Any of the cocoyam accessions may be recommended for consumption for improved protein and mineral nutrients while tubers of accession UFCe7 have also shown good promise in terms of protein and fibre content availability. The results of the in vivo study, using the liver and kidney functional endpoints of weanling albino rats (Rattus norvegicus) maintained on different accessions of cooked cocoyam-based iii diets (UFCe1-UFCe7) for 28 days, revealed that all the accessions produced selective alterations on the hepatorenal indices of weanling rats. The highest alterations were produced by UFCe4 while the least was from UFCe2. These alterations may have consequential effects on the normal functioning of the liver and kidney of the animals. The UFCe2 exhibited the least toxicity risk among the accessions of C. esculenta growing in KwaZulu-Natal Province of South Africa.

Resumen
<p>Feed mills demand routine techniques to analyze digestible amino acids in highly variable animal meals. As routine tools, infrared spectroscopic predictions of digestible amino acids require reference samples assayed in vivo. Lack of reference samples resulting from costly and time-consuming in vivo assays has limited infrared spectroscopic applications. To remove this limitation, an in vitro assay mimicking in vivo digestion in swine was sought as a replacement to build the reference database.<p>Pepsin and pancreatic proteases used in the in vitro assays produce autolysates that are assayed as digestible amino acids. To correct this contamination and define incubation time for efficient use of the proteases, the autolysis of these proteases was studied.

Resumen
Our study explored the impact of adding avocado to chicken liver pate, focusing on both nutritional composition, oxidative stability and organoleptic (sensory) characteristics. By incorporating avocado, we aimed to create a healthier, more nutritious alternative to traditional pate. Nutritional analysis included determining protein, fat, minerals, water, salt, carbohydrate content, and energy value. The results showed that adding avocado led to a decrease in fat content and an increase in beneficial omega-3 fatty acids and dietary fiber. Peroxide value (PV), TBA value and total oxidation (TOTOX) were determined to assess oxidative stability. These changes significantly improved the pate�s nutritional profile, making it a healthier choice. We also evaluated organoleptic properties, assessing the pate�s taste, smell, texture, and color. Sensory analysis was conducted with a panel of participants who rated the avocado pate on these attributes. The feedback indicated that the avocado-enhanced pate was well-received, with positive ratings for its appearance, flavor, and smooth consistency. The fresh taste of avocado complemented the richness of the chicken liver, while the bright green color added visual appeal. In conclusion, the addition of avocado to chicken liver pate not only improved its nutritional content but also maintained or enhanced its sensory qualities. This suggests that avocado pate is a flavorful and healthy alternative, appealing to consumers looking for both nutrition and taste.

Resumen
The aims of this study were to investigate nutritional value of coldpressed sunflower oil produced in the Republic of Serbia. Composition of fatty acids was determinated and, based on individual fatty acid content, nutritional indices are calculated. Tocopherol composition and total content of carotenoids and chlorophylls were investigated as well. The results indicate that examined oil is rich in essential linoleic acid and with excellent values of nutritional indices. Unfavorable n-6/n-3 ratio is caused by low n-3 fatty acids content which is characteristic for sunflower oil. Total tocopherol content was unexpected low while content of pigments was characteristic for this type of oil

Resumen
Rapeseed meal is a valuable source of protein for animals feeding. It can be used as an alternative to soybean meal in the mixtures of combined feeds intended for farm animals. Thus, the purpose of this study was to evaluate the chemical and nutritional composition of the rapeseed meal intended for use in the feeding of monogastric livestock. 70 samples of rapeseed meal arrived at the Laboratory of Chemical Analyses for Animal Nutrition, were analysed. The following values were obtained for the main nutritional compounds: crude protein (CP) � 37.95%, with variations between 35.26 and 41.67%; ether extract (EE) � 1.84%, with values between 1.55 � 2.06%; crude fiber (CF) � 11.93%, with variations between 9.85 � 14.93%; and nitrogen-free extracts (NfE) � 41.07%, varying significantly between 35.75 � 45.82%. In order to evaluate the nutritional value of rapeseed meal, the digestible forms of nutrients and the value of metabolizable energy (ME) for pigs and poultry were calculated, using predictive formulas. The average ME value for pigs was 1278.57 kcal/kg, varying between 1145.63 - 1398.27 kcal/kg, and for poultry the ME value was 935.06 kcal/kg, being between 837.90 - 1022.55 kcal/kg. These data underline the importance of the chemical and nutritional evaluation of feed ingredients before they are included in the diets of farm animals in order to have the certainty of correctly calculated rations and to ensure the amounts of nutrients in accordance with their feeding norms, in order to maximize animal production.

Resumen
Improving the nutrition of people has always been one of the main tasks of people. If a person eats junk food, then he has a metabolic disorder, the functional ability of the digestive, cardiovascular, nervous and other body systems. Demographic difficulties, frequent stresses, an increase in the number of people suffering from various diseases, deterioration in the health of children, etc., all these factors necessitate the introduction of additional raw materials that increase the nutritional and biological value of food products, in particular bread and bakery products.

Resumen
Food is an essential to our existence but under certain conditions it could become the origin to the accumulative health damages. Technological processes as heating, chopping, mincing, grounding, promote the lipid oxidation process in muscle tissues and meat foodstuffs. Lipid oxidation occurred rapidly in turkey muscle, intermediate in duck, and slowest in chicken during frozen storage. Depletion of tocopherol during frozen storage was more rapid in turkey and duck compared to chicken. These processes developed from lipid peroxides produce many cytotoxic compounds including malondialdehyde (MDA). The muscle tissue is further oxidized in stomach conditions producing additional cytotoxic compounds. Oxidized lipids that are formed during digestion of a meal possess the potential to promote reactions that incur vascular diseases. A grape seed extract (1% of the meat weight) and butylated hydroxytoluene (0.2% of the lipid weight) were each effective at preventing formation of lipid oxidation products for 3 hours during co-incubation with cooked turkey meat in simulated gastric fluid (SGF). Polyphenols in the human diet, as an integral part of the meal prevent the generation and absorption of cytotoxic compounds and the destruction of essential nutrients, eg. antioxidants vitamins during the meal. Polyphenols act as antioxidants in the gastrointestinal tract; they scavenge free radicals and may interact with reactive carbonyls, enzymes and proteins. These all reactions results in decreasing the absorption of reactive carbonyls and possible other cytotoxic compounds into the plasma. Consumptions of diet high in fat and red meat are contributory risk factors partly due to an increase production of cytotoxic oxidized lipid products eg. MDA. However, the simultaneously consumption of polyphenols rich foods reduce these factors. Locating the biological site of action of polyphenols in the in the gastrointestinal tract may explain the paradox between the protective effect of a highly polyphenols rich diet and the low bioavailability of these molecules in human plasma. It may also explain the "French paradox" and the beneficial effect of Mediterranean and Japanese diets, in which food products with high antioxidants content such as polyphenols are consumed during the meal.

Resumen
Objectives To determine endocrine factors that regulate the partitioning of amino acids by the mammary gland. To evaluate dietary flow and supply of energy and amino acids and their effects on milk protein synthesis and endocrine status. To use primary cultures of cow mammary epithelial cells to examine the role of specific factors on the rates and pattern of milk protein synthesis. Milk protein is an increasingly valuable component of milk but little is known regarding the specific hormonal and nutritional factors controlling milk protein synthesis. The research conducted for this project has determined that milk protein synthesis has the potential to be enhanced much greater than previously believed. Increases of over 25% in milk protein percent and yield were detected in studies utilizing abomasal infusion of casein and a hyperinsulinemic-euglycemic clamp. Thus, it appears that insulin, either directly or indirectly, can elicit a substantial increase in milk protein synthesis if additional amino acids are supplied. For additional amino acids, casein provided the best response even though substantial decreases in branched chain amino acids occur when the insulin clamp is utilized. Branched chain amino acids alone are incapable of supporting the enhanced milk protein output. The mammary gland can vary both blood flow and extraction efficiency of amino acids to support protein synthesis. A mammary culture system was used to demonstrate specific endocrine effects on milk protein synthesis. Insulin-like growth factor-I when substituted for insulin was able to enhance casein and a-lactalbumin mRNA. This suggests that insulin is a indirect regulator of milk protein synthesis working through the IGF system to control mammary production of casein and a-lactalbumin. Principal component analysis determined that carbohydrate had the greatest effect on milk protein yield with protein supply only having minor effects. Work in cattle determined that the site of digestion of starch did not affect milk composition alone but the degradability of starch and protein in the rumen can interact to alter milk yield. Cows fed diets with a high degree of rumen undegradability failed to specifically enhance milk protein but produced greater milk yield with similar composition. The mammary gland has an amazing ability to produce protein of great value. Research conducted here has demonstrated the unprecedented potential of the metabolic machinery in the mammary gland. Insulin, probably signaling the mammary gland through the IGF system is a key regulator that must be combined with adequate nutrition in order for maximum response.
