Résumé :

Freeze storage and pasteurization of human milk are common treatments in milk banks. Thermal treatment changes the quality of milk for preterm infants? nutrition, and the aim of this paper was to examine the nutritional profile and antioxidant potential of preterm human milk after storage and pasteurization, and also after supplementation with fortifier. The effects of storage processes were estimated on mature preterm milk of 30 breastfeeding women. Total proteins, lipids and lactose were determined after thermal processing and supplementation of mature preterm milk with fortifier. The antioxidant capacity was determined using the ferric reducing antioxidant potential method and lipid peroxidation inhibition assay. Protein concentration decreased after frozen storage and pasteurization (p<0.05). Pasteurization further reduced the lipid concentration after freezing. The ferric reducing antioxidant potential decreased after thermal treatments (p<0.05). Supplementation of mature milk with fortifier increased the concentration of proteins, lipids and lactose. Our findings demonstrated that storage and pasteurization processes affect the basic nutritional composition and antioxidant capacity of preterm human milk. In order to ensure adequate nutrition for preterm infants with preterm human milk, supplementation, especially with high concentrations of proteins and lipids, is necessary after thermal treatments.

Résumé :

Human milk lipids provide the infant with energy and essential vitamins, polyunsaturated fatty acids, and bioactive components. Adding complex lipids and milk fat globule membranes to vegetable oil-based infant formula has the potential to enhance infant development and reduce infections. Cholesterol provision with breastfeeding modulates infant sterol metabolism and may induce long-term benefits. Some 98-99% of milk lipids are comprised by triacylglycerols, whose properties depend on incorporated fatty acids. Attention has been devoted to the roles of the long-chain polyunsaturated fatty acids docosahexaenoic (DHA) and arachidonic (ARA) acids. Recent studies on gene-diet interaction (Mendelian randomization) show that breastfeeding providing DHA and ARA improves cognitive development and reduces asthma risk at school age particularly in those children with a genetically determined lower activity of DHA and ARA synthesis. It appears prudent to follow the biological model of human milk in the design of infant formula as far as feasible, unless conclusive evidence for the suitability and safety of other choices is available. The recent European Union legislative stipulation of a high formula DHA content without required ARA deviates from this concept, and such a novel formula composition has not been adequately evaluated. Great future opportunities arise with significant methodological progress for example in lipidomic analyses and their bioinformatic evaluation, which should enhance understanding of the biology of human milk lipids. Such knowledge might lead to improved dietary advice to lactating mothers as well as to further opportunities to enhance infant formula composition.

Résumé :

The aim: evaluate natural canned Japanese mackerel as specialized products for dietary nutrition based on indicators of nutritional and biological value, as well as lipid health indices. The methods: The nutritional (chemical composition) and biological value of canned Japanese mackerel, the composition of lipids and fatty acids were studied, on the basis of which lipid indices of atherogenicity, thrombogenicity and hypocholesterolemic coefficient were calculated, characterizing the dietary properties of canned Japanese mackerel. The results: It has been established that the process of high-temperature preservation of Japanese mackerel does not cause significant changes in the nutrient composition of the product. Canned Japanese mackerel is characterized by a high content of phospholipids (7.80 ± 1.1 of the total lipids or 1.41 ± 0.3 g per 100 g of the product) and PUFAs of the omega-3 family (32.26 % of the number of fatty acids). The index of atherogenicity of the lipid profile of canned food was 0.57, thrombogenicity — 0.16, and hypocholesterolemic coefficient — 2.80. Conclusions: Canned Japanese mackerel are characterized by high nutritional and biological value and are a rich source of essential lipids. The lipid indices of canned Japanese mackerel characterize the potential for the product to normalize lipid metabolism in humans and reduce the risk of developing diseases of the cardiovascular system. The newness: Based on a new methodological approach to assessing the lipid profile of canned Japanese mackerel, a possible positive effect of the product on cholesterol metabolism and the rate of thrombus formation in human blood vessels was shown. The practical significance: Natural canned food from Japanese mackerel can be recommended for inclusion in the diet of certain population groups as specialized products for dietary preventive nutrition.

Résumé :

Economic viability of biodiesel production relies mainly on the productivity of biomass and microalgal lipids. In addition, production of omega fatty acids is favorable for human nutrition. Thus, enhancement of lipid accumulation with high proportion of omega fatty acids could help the dual use of microalgal lipids in human nutrition and biodiesel production through biorefinery. In that context, phytohormones have been identified as a promising factor to increase biomass and lipids production. However, nitrogen limitation has been discussed as a potential tool for lipid accumulation in microalgae, which results in simultaneous growth retardation. The present study aims to investigate the combined effect of N-depletion and 3-Indoleacetic acid (IAA) supplementation on lipid accumulation of the marine eustigmatophyte Nannochloropsis oceanica as one of the promising microalgae for omega fatty acids production. The study confirmed that N-starvation stimulates the lipid content of N. oceanica. IAA enhanced both growth and lipid accumulation due to enhancement of pigments biosynthesis. Therefore, combination effect of IAA and nitrogen depletion showed gradual increase in the dry weight compared to the control. Lipid analysis showed lower quantity of saturated fatty acids (SFA, 26.25%) than the sum of monounsaturated (MUFA) and polyunsaturated fatty acids (PUFA). Under N-depletion, SFA decreased by 12.98% compared to the control, which recorded much reduction by increasing of IAA concentration. Reduction of SFA was in favor of PUFA, mainly omega-6 and omega-3 fatty acids which increased significantly due to IAA combined with N-depletion. Thus, the present study suggests a biorefinery approach for lipids extracted from N. oceanica for dual application in nutrition followed by biodiesel production.

Résumé :

Lipids from milk fat globule membranes (MFGMs) and extracellular vesicles (EVs) are considered beneficial for cognitive development and human health. Milk-derived whey concentrates rich in these lipids are therefore used as ingredients in infant formulas to mimic human milk and in medical nutrition products to improve the metabolic fitness of adults and elderly people. In spite of this, there is no consensus resource detailing the multitude of lipid molecules in whey concentrates. To bridge this knowledge gap, we report a comprehensive and quantitative lipidomic resource of different whey concentrates. In-depth lipidomic analysis of acid, sweet, and buttermilk whey concentrates identified 5714 lipid molecules belonging to 23 lipid classes. The data show that the buttermilk whey concentrate has the highest level of fat globule-derived triacylglycerols and that the acid and sweet whey concentrates have the highest proportions of MFGM- and EV-derived membrane lipids. Interestingly, the acid whey concentrate has a higher level of cholesterol whereas sweet whey concentrate has higher levels of lactosylceramides. Altogether, we report a detailed lipid molecular compendium of whey concentrates and lay the groundwork for using in-depth lipidomic technology to profile the nutritional value of milk products and functional foods containing dairy-based concentrates.

Résumé :

Dietary lipids have a major role in nutrition, not only for their fuel value, but also as essential and bioactive nutrients. This narrative review aims to describe the current evidence on nutrigenomic effects of dietary lipids. Firstly, the different chemical and biological properties of fatty acids contained both in plant- and animal-based food are illustrated. A description of lipid bioavailability, bioaccessibility, and lipotoxicity is provided, together with an overview of the modulatory role of lipids as pro- or anti-inflammatory agents. Current findings concerning the metabolic impact of lipids on gene expression, epigenome, and gut microbiome in animal and human studies are summarized. Finally, the effect of the individual’s genetic make-up on lipid metabolism is described. The main goal is to provide an overview about the interaction between dietary lipids and the genome, by identifying and discussing recent scientific evidence, recognizing strengths and weaknesses, to address future investigations and fill the gaps in the current knowledge on metabolic impact of dietary fats on health.

Résumé :

The objectives of the present study were to examine the effects of dietary fat type and level of energy intake on hypothalamic leptin binding affinity and membrane fatty acid composition, circulating leptin levels, and body weight homeostasis in rats. Animals were fed diets containing tallow, safflower oil, or menhaden oil (20% wt/wt) for 10 wks, ad libitum or at 60% of ad libitum intakes. Specific leptin binding could not be detected in hypothalamic membrane homogenates; hypothalamic leptin levels were unaffected by diet or energy intake. Levels of tracer exceeding assay reference values were found in homogenates, suggesting intra-membrane binding. Excess tracer levels were weakly associated (p < 0.07) with the sum of hypothalamic phospholipid monounsaturates. Restriction lowered weight gain and food intakes (p < 0.0001 for both). In hypothalamic phospholipids, energy restriction lowered levels of 18:3(n-3) and increased levels of 20:1(n-9), 20:4(n-6), and 22:4(n-6) (p < 0.05, p < 0.02, p < 0.05, and p < 0.04, respectively). Fat type and energy level interactively affected hypothalamic levels of 20:4(n-6), 22:5(n-3) and 22:6(n-3) (p < 0.05, p < 0.006, and p < 0.05, respectively). Restriction lowered circulating leptin levels (p < 0.0001); overall plasma leptin levels were marginally associated (p < 0.07) with hypothalamic 16:0 concentrations. The results of the study support previous findings suggesting that leptin binding at the level of the hypothalamic membrane may not be detectable. The results also support the lack of a dietary fat effect on plasma leptin levels and levels of certain hypothalamic fatty acids, such as 20:4(n-6), 22:4(n-6), and 22:5(n-3), with energy restriction. The findings of the study suggest a link between increased membrane fluidity, increased binding affinity, and lower circulating leptin levels, promoting the possibility that the biological actions of leptin can be controlled through dietary effects on

Résumé :

My thesis research has examined the fatty acid composition of serum triacylglycerol, phospholipid and cholesterol ester in 2793 participants who took part in the 1997 National Nutrition Survey - a national population-based survey of New Zealand adolescents and adults aged or [greater than or equal to]̲15 y. Differences in serum fatty acids by sex, age, ethnicity, body mass index and smoking - independent of dietary fat intake - were determined. Serum fatty acids were used as biomarkers of saturated and polyunsaturated fat intake to predict population serum total cholesterol concentrations. The association between n-3 long-chain polyunsaturated fatty acids in serum phospholipid and mental and physical wellbeing, as assessed by the short form-36, was determined. Serum fatty acids have been used as biological markers of fat intake and to predict the risk of disease. The fatty acid composition of serum triacylglycerol, phospholipid and cholesterol ester is subject to alteration by dietary fat but overall, is largely controlled by metabolic enzymes. Non-dietary variables - sex, age, body mass index or cigarette smoking - may influence the activity of these enzymes, which will subsequently alter the fatty acid composition but the extent to which these affect serum fatty acid composition in the general population is poorly understood. Our results showed that the proportion of docosahexaenoic acid in serum phospholipid and cholesterol ester was significantly greater in women by 0.15 and 0.02 mol%, respectively in comparison to men whereas, the proportion of eicosapentaenoic acid was significantly greater in men by 0.08 and 0.1 mol%, respectively, after adjusting for age, ethnicity, body mass index and smoking. A number of differences in the proportion of palmitoleic acid in serum triacylglycerol, phospholipid and cholesterol ester were detected; palmitoleic acid increased across the age categories in women (15-24, 25-44, 45-64 65+ y), was higher in women compared to men, New Zealand Europeans compared to New Zealand Maori and Pacific People, those with a body mass index or [greater than or equal to] 30 kg/m� compared to those with a body mass index < 25 kg/m� and in current smokers in comparison to non-smokers. In women, there was an inverse trend in the proportion of linoleic acid in serum phospholipid and cholesterol ester across the age categories. The proportion of linoleic acid in serum triacylglycerol, phospholipid and cholesterol ester was lower in smokers by 2.19, 1.04 and 0.75 mol%, respectively in comparison to non-smokers. None of these differences could be explained by a difference in dietary fat intake. Consequently, sex appears to affect the metabolism of n-3 long-chain polyunsaturated fatty acids independent of dietary fat intake and metabolic differences associated with age, body mass index and smoking may be at play for a number of other serum fatty acids notably, palmitoleic and linoleic acids. Evidence for a role of dietary fat as a predictor of serum cholesterol concentrations in the general population is conflicting. On one hand, results from cholesterol-lowering dietary intervention trials show unequivocally that decreasing saturated fat intake produces a meaningful reduction in serum cholesterol concentrations. On the other hand, the results of large observational studies show little association between saturated fat intake and cholesterol concentrations. The lack of association in the latter studies may result from errors in dietary assessment and therefore, using serum fatty acids as biomarkers of fat intake may overcome the limitations associated with typical dietary assessment techniques. Participants were divided into quintiles of increasing proportion of serum fatty acids. Each one SD increase in the myristic acid composition of serum cholesterol ester, triacylglycerol and phospholipid was associated with an increase in cholesterol of 0.19, 0.10 and 0.13 mmol/L, respectively after adjusting for confounding variables. The difference in cholesterol concentrations between those categorised into the highest and lowest quintiles of serum cholesterol ester myristate was 0.48 mmol/L. A one SD increase in the linoleic acid composition of serum cholesterol ester, triacylglycerol and phospholipid corresponded to a decrease in cholesterol of 0.07, 0.05 and 0.07 mmol/L, respectively. The difference in cholesterol concentrations between the 1st and 5th quintiles of serum cholesterol linoleate was 0.18 mmol/L. Intake of saturated and polyunsaturated fats, as measured using serum fatty acids, are important determinants of cholesterol concentrations in New Zealanders. It has been hypothesised that a lower intake of n-3 long-chain polyunsaturated fatty acids, largely of marine origin, is implicated in the aetiology of depressive disorder. Results from the majority of observational studies have shown that depressed participants have a lower proportion of eicosapentaenoic or docosahexaenoic acid in phospholipids compared to controls but evidence for an improvement in depressive symptoms after supplementation with n-3 long-chain polyunsaturated fatty acids is conflicting. There is little known about the role that n-3 long-chain polyunsaturated fatty acids may have as predictors of mental wellbeing in the general population. Participants were categorised into quintiles of increasing n-3 long-chain polyunsaturated fatty acids in serum phospholipid. There was no significant trend in self-reported mental wellbeing - the mental component score - across the quintiles of eicosapentaenoic, docosapentaenoic and docosahexaenoic acids or the sum of these three fatty acids after adjusting for confounding variables. There was a significant trend in the mental component score across the quintiles of the ratio of eicosapentaenoic/arachidonic acid; the difference between the highest and the lowest quintile was 6.6 points. There were significant positive trends in self-reported physical health - the physical component score - across the quintiles of eicosapentaenoic and docosapentaenoic acids as well as the ratio of eicosapentaenoic/arachidonic acid ratio; the difference between the 1st and 5th quintiles were 8.6, 6.0 and 8.9 points, respectively. Overall, there appears to be little association between the n-3 long-chain polyunsaturated fatty acid composition of serum phospholipid and self-reported mental health in a population of low fish consumers; however, the proportion of n-3 long-chain polyunsaturated fatty acids may be an important predictor of physical wellbeing in New Zealanders.

Résumé :

In a cross-sectional study we examined Iipoprotein composition and CETP mass in 15 sedentary and 12 exercising, healthy male volunteers, aged between 17-35 years. The exercising group were defined as individuals participating in at least five weekly 45 minute exercise sessions of an aerobic nature (60-85% estimated maximal oxygen uptake). The sedentary subjects were only irregularly engaged in bouts of physical activity, not more than 45 minutes per week. Seasonal data were collected: one data collection in the fall and one in the spring. A 20 day food and exercise journal was maintained during each season's data collection period. Blood lipids were measured on two and anthropometric and aerobic capacity testing were performed on 1 occasion during each season. Statistical analyses consisted of a two way ANOVA (exercise and season) to control for seasonal effects on blood lipids and Iipoprotein levels. Pearson product moment correlations were calculated between those variables that showed significant seasonal or level of activity changes. Exercising males consumed significantly greater amounts of energy (p

Résumé :

More than six billion people worldwide consume dairy products every day. Dairy products and their constituents contain hundreds of different components, but milk fat globule membrane (MFGM) polar lipids are still underestimated from a nutritional point of view. The unique composition of phospholipids (PLs) – the main MFGM component – provides high nutraceutical properties. Therefore, the research of bioactive dairy components and their impact has promising potential in human health by various mechanisms. The positive effects of MFGM PLs are mainly based on animal studies, but there are a small number of in vivo studies with volunteers. The present study aimed to review the research findings of dairy PLs in human nutrition and their functional properties. Dairy PLs effectively impact intestinal integrity and gut microbiota, lipid profile and risk lowering of cardiovascular diseases (CVDs), cognitive performance during stress, and neonatal brain development.

Résumé :

Globally $232 billion was spent in the pet industry in 2021 and the compound annual growth rate (CAGR) is estimated to be 4.6%. In the USA alone, $109.6 billion was spent in 2021, and more money is spent annually on pet food and treats than veterinary care or products. Pet parents are increasingly more concerned about the nutritional quality of the foods they feed their animals and their impact on health. Pet food manufacturers are responding to the increased demand for premium food products but importantly, the work of veterinary nutrition researchers is key to ensuring the safety and nutritional sufficiency of commercial and specialized animal diets. Lipids and related nutrients, such as omega-3 polyunsaturated fatty acids, medium-chain triglyceride oil (MCT oil), vitamins D and E and choline play an important role in companion animal health and will be discussed in this session. In addition, a study evaluating the impact of canine diets with different fat contents on risk of pancreatitis will be presented. These reports not only provide more insight into companion animal health but also sheds light on our understanding of how lipids and related nutrients impact human health.

Texte intégral

Résumé :

Beyond meeting nutritional requirements for growth and maintenance, select dietary ingredients can have additional effects, intended or not, on animal physiology and immune function. Diets can be enriched to benefit the animal, and a dual benefit can be achieved in the case of enriching animal products for the downstream human consumer. Many immune-altering nutrients are fat-soluble, including Vitamin E and D. Importantly, dietary lipids themselves can impact immune function; therefore, a focused and intentional selection of specific dietary fats, specifically omega-3 polyunsaturated fatty acids (PUFA), is one method to alter inflammatory cascades in animals consuming the diet. Examples of other related ingredients to which the immune system is responsive include zinc and probiotics. While work in human, livestock, and companion animal models is working to identify therapeutic inclusion rates for these nutrients and ingredients, it should be noted that physiological alterations are seen in both over and under-inclusion and are nutrient-specific. For example, inclusion above currently recommended levels may optimize immune function and reduce inflammation in the case of vitamin D or omega-3 PUFA, while for zinc, additional pharmacological supplementation above requirements may inhibit immune function. Importantly, when a diet is formulated to reduce overall systemic inflammation, it must be considered that important â€œbackgroundâ€ functions of the immune system, including monitoring for and clearing pathogenic microbial populations, may be down-regulated due to a general reduction in immune reactivity. Continued work to understand how diet and nutrition impact immunity, and how to balance inflammation through nutrition, is an area of active research and will inform downstream users how to best use data to impact consumers of that feed in desirable ways.

Texte intégral

Résumé :

Irradiation is a non-thermal process used for preservation and decontamination of human and animal food products. Although irradiation process causes minimal changes to the sensory and nutritional quality, certain irradiation-specific compounds form, such as free radicals and related lipid radiolysis products, which can have organoleptic and health concerns, especially at high doses of 50 kGy or more. For example, radiolysis of palmitic acid-containing lipids typically results in the formation of a unique irradiation marker 2-dodecylcyclobutanone (2-DCB) along with other hydrocarbons (tridecane, 1-tetradecene, tetradecane, 1-pentadecene). Analysis of these irradiation-specific molecules can also be used to back-trace irradiation history of the products. This study involves with the quantitative and mechanistic analysis of the lipid radiolysis products in parallel to changes in the amount of precursor lipid molecules in two dried meat matrixes (e.g., chicken jerkies and pig ears) using SPME-coupled GC-MS analysis. Overall, the formation of rate if 2-DCB was higher (p < 0.05) than hydrocarbons both following zero order kinetics; whereas, the decrease in precursor fatty acids followed first order kinetics. The quantitative analysis requires the use of a suitable internal standard (IS), which can interact with the extraction of the analyte (e.g., 2-DCB) below a critical concentration. This critical concertation was an order of magnitude large in pig ears (>80 ppb) than chicken jerkies (>8 ppb) in parallel to the amount of precursor lipid. Finally, electron paramagnetic resonance spectroscopy was employed complementary to GC-MS analysis, however, providing confirmatory information. The findings of this research help to elucidate the irradiation-specific changes in irradiated meat matrices using an analytical method that also allows quantitative analysis of small sample volumes.

Résumé :

The study of and interest in microbial lipids go back for at least 140 years. Historically, the production of these microbial oils was expensive and complex as compared to the inexpensive, consistent, and robust production of plant oils. Additionally, the attributes of these microbial oils were often similar to commoditized plant oils. In the 1960s and 1970s, more focus shifted to the discovery of unique attributes of microbial oils and the development of these systems led to some minor commercialization of nutritional microbial lipids in the 1970s and 1980s. Starting in the 1990s, and continuing today, significant success in the development and commercialization of nutritional microbial oils containing Omega-3 and Omega-6 long-chained polyunsaturated fatty (PUFA) acids has been seen. Progress continues to be made in the technology of microbial lipid production in both genetically modified and non-genetically modified systems. While the interest level in microbial lipids and systems continues to run high, there has only been relatively narrow success in commercialization of PUFA microbial oils to date. The presentation will review the history, status, and future challenges and opportunities for microbial lipids for nutrition.

Texte intégral

Résumé :

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.

Texte intégral

Résumé :

Various unicellular algae produce omega-3 (w3) very-long-chain polyunsaturated fatty acids (VLC-PUFA), which are rarely found in higher plants. In this research and other studies from our laboratories, it has been demonstrated that the marine unicellular alga Nannochloropsis (Eustigmatophyceae) can be used as a reliable and high quality source for the w3 VLC-PUFA eicosapentaenoic acid (EPA). This alga is widely used in mariculture systems as the primary component of the artificial food chain in fish larvae production, mainly due to its high EPA content. Furthermore, w3 fatty acids are essential for humans as dietary supplements and may have therapeutic benefits. The goal of this research proposal was to understand the physiological and biochemical mechanisms which regulate the synthesis and accumulation of glycerolipids enriched with w3 VLC-PUFA in Nannochloropsis. The results of our studies demonstrate various aspects of lipid synthesis and its regulation in the alga: 1. Variations in lipid class composition imposed by various environmental conditions were determined with special emphasis on the relative abundance of the molecular species of triacylglycerol (TAG) and monogalactosyl diacylglycerol (MGDG). 2. The relationships between the cellular content of major glycerolipids (TAG and MGDG) and the enzymes involved in their synthesis were studied. The results suggested the importance of UDP-galactose diacylglycerol galactosyl (UDGT) in regulation of the cellular level of MGDG. In a current effort we have purified UDGT several hundredfold from Nannochloropsis. It is our aim to purify this enzyme to near homogeneity and to produce antibodies against this enzyme in order to provide the tools for elucidation of the biochemical mechanisms that regulate this enzyme and carbon allocation into galactolipids. 3. Our in vitro and in vivo labeling studies indicated the possibility that phosphatidylcholine (PC) and phosphatidylethanolamine (PE) are associated with desaturation of the structural lipids, whereas shorter chain saturated fatty acids are more likely to be incorporated into TAG. 4. Isolation of several putative mutants of Nannochloropsis which appear to have different lipid and fatty acid compositions than the wild type; a mutant of a special importance that is devoid of EPA was fully characterized. In addition, we could demonstrate the feasibility of Nannochloropsis biomass production for aquaculture and human health: 1) We demonstrated in semi-industrial scale the feasibility of mass production of Nannochloropsis biomass in collaboration with the algae plant NBT in Eilat; 2) Nutritional studies verified the importance algal w3 fatty acids for the development of rats and demonstrated that Nannochloropsis biomass fed to pregnant and lactating rats can benefit their offspring.

Texte intégral

Résumé :

Zambians in all walks of life are affected by malnutrition, and working through human rights is one key way to address this injustice. Based on research aiming to understand how a ‘right to nutrition’ is perceived by different actors globally and in Zambia, this brief presents a clear framework for a rights-based approach to nutrition in Zambia. This framework identifies rhetorical, legal and practical functions of human rights, and offers a way to think through clearly how different actors might work on the different aspects of rights. Addressing these three aspects of a right to nutrition all together – instead of by very separate constituencies as happens now – is fundamental to a coherent rights-based approach to nutrition. This brief outlines which actors need to come together – from law and policy, activism and communities, across global, national and local levels – and suggests how to start. It lays out the Zambian policy, legal and practical environment as it stands, and suggests actions to move forward in each of these areas in ways that are consistent with the different aspects of rights. Through these steps, Zambia can become known as a hub of action on a right to nutrition, to join with others in using human rights to address the injustice of malnutrition.

Résumé :

Diet-related disease, climate change, and environmental degradation exact an enormous toll on human and planetary health. These challenges could be addressed in part by shifting what we eat and how we produce food, yet key questions remain about how to make such transitions effective, equitable, and sustainable. To help answer these questions, investments in “sustainable nutrition science”—research and education at the intersection of nutrition, food production, and climate and environment—are urgently needed. However, the Union of Concerned Scientists has found that US public funding for sustainable nutrition science is severely limited, totaling an estimated $16 million annually between 2016 and 2019, and recommends more than tripling that amount in response to our devastating public health and environmental crises.
