Texte intégralRésumé :
An alarming increase in stressful situations, psycho-emotional stress, physical inactivity, global indicators of overweight caused by the achievements of civilization, aggressive advertising and the availability of food products lead to the emergence of modern chronic diseases of the population in many countries of the world. The urban population was isolated from the use of a sufficient amount of natural plant materials with corrective and healing effects. As a result, the growth of new nutritionally dependent diseases is diagnosed. The solution to these problems can be found in the production of vegetable multicomponent functional food ingredients with a given chemical and biological composition, intended for inclusion in food formulations. A pragmatic approach allows you to make small changes to the traditional food environment and provide the population with healthy food. The aim of the work was to investigate modern scientific approaches to the design, development and production of food ingredients from non-traditional plant materials, their use in the food industry with the availability of scientific evidence of beneficial effects. Plants are a valuable source of biologically active substances. In many countries of the world, researchers study the national flora in terms of their nutritional and pharmacological properties, improve extraction methods, and design complex compounds to increase bioavailability. Discussions are continuing on methods for modeling multicomponent ingredients based on modern information systems, with the goal of optimizing and predicting the final product. There is a growing demand for healthy products manufactured using non-traditional types of food healing local plant materials: thistle meal (Lat. S?lybum mari?num), marsh saber root extract (Lat. C?marum pal?stre), etc. The use of a wide range of ingredients pays attention to foreign countries from non-traditional plant materials, for example, encapsulated banana peels in Australia, the use of lyophilized nettle extract in chocolate production in Croatia.

Texte intégralRésumé :
Background: Adolescent is a transition phase from childhood to adulthood that marked by the change on physical, mental and psychosocial aspect. Adaptation on the change that people met in their life is called psychosocial stress. Stress makes a change on food habit and a disturbance on nutrition’s absorbance. Those circumstances affect people’s nutritional status.Objectives: To identify the correlation between psychosocial stress and nutritional status among SMP Stella Duce 1 Yogyakarta’s students.Methods: This study was an observational study which used a cross sectional design. It held by quantitative approach to identify the relationship between psychosocial stress and nutritional status. Subject of the study were 85 students of SMP Stella Duce 1 Yogyakarta. Respondent’s identities were collected by using identity questionnaire. Psychosocial stress’s status was collected by using SRRS questionnaire (social readjustment rating scale) that was modified for adolescent. Respondent’s calories intakes were assessed by using the form food recall 3 x 24 h. Anthropometrics data collected were weight and height. The adjustment of psychosocial stress’s status used SRRS questionnaires. Calories intake were measured by using nutrition software (Fp2). Student’s nutritional status was measured by using Epi 2000 software. Relationship’s analysis among variables uses statistical test of SPSS 12.00, with the correlation or linear regression test.Result: From this study, 49.4% (42 people) have normal nutritional status, 4.7 % at under nutrition level, 25.9% at risk of obesity, and 20% obesity. From the measurement of psychosocial stress’s score, there were 61.2% (52 people) in a non-tress condition, while the other was on stress at different level. Statistical test showed that there was no relationship between psychosocial stress and nutritional status (p > 0.05).Conclusion: There was no significant relationship between psychosocial stress and nutritional status among SMP Stella Duce 1 Yogyakarta’s students.

Texte intégralRésumé :
Background There are an increasing number of mobile apps that provide dietary guidance to support a healthy lifestyle and disease management. However, the characteristics of these nutrition-related apps are not well analyzed. Objective This study aimed to evaluate the functionality and quality of nutrition-related apps in China. Methods Mobile apps providing dietary guidance were screened in the Chinese iOS and Android app stores in November 2017, using stepwise searching criteria. The first screening consisted of extracting information from the app descriptions. Apps that (1) were free, (2) contain information on diet and nutrition, and (3) were last updated after January 1, 2016, were downloaded for further analysis. Nutritional functionalities were determined according to the Chinese Dietary Guidelines framework. Market-related functionalities were developed from previous studies and tailored to downloaded apps. The quality of apps was assessed with the user version of the Mobile App Rating Scale (uMARS). Results Out of 628 dietary guidance apps screened, 44 were nutrition-related. Of these, guidance was provided on diet exclusively (11/44, 25%), fitness (17/44, 39%), disease management (11/44, 25%), or maternal health (5/44, 11%). Nutritional functionalities included nutritional information inquiry (40/44, 91%), nutrition education (35/44, 80%), food record (34/44, 77%), diet analysis (34/44, 77%), and personalized recipes (21/44, 48%). Dietary analysis and suggestions mainly focused on energy intake (33/44, 75%) and less on other factors such as dietary structure (10/44, 23%). Social communication functionalities were available in 42 apps (96%), user incentives were supported in 26 apps (59%), and intelligent recognition technology was available in 8 apps (18%). The median score for the quality of the 44 apps, as determined on a 5-point uMARS scale, was 3.6 (interquartile range 0.7). Conclusions Most nutrition-related apps are developed for health management rather than for dietary guidance exclusively. Although basic principles of energy balance are used, their nutritional functionality was relatively limited and not individualized. More efforts should be made to develop nutrition-related apps with evidence-based nutritional knowledge, comprehensive and personalized dietary guidance, and innovative technology.

Journal of the Academy of Marketing Science 49, no 1 (24 avril 2020) : 119–38. http://dx.doi.org/10.1007/s11747-020-00723-5.
Texte intégralRésumé :
AbstractTo examine whether four pre-selected front-of-pack nutrition labels improve food purchases in real-life grocery shopping settings, we put 1.9 million labels on 1266 food products in four categories in 60 supermarkets and analyzed the nutritional quality of 1,668,301 purchases using the FSA nutrient profiling score. Effect sizes were 17 times smaller on average than those found in comparable laboratory studies. The most effective nutrition label, Nutri-Score, increased the purchases of foods in the top third of their category nutrition-wise by 14%, but had no impact on the purchases of foods with medium, low, or unlabeled nutrition quality. Therefore, Nutri-Score only improved the nutritional quality of the basket of labeled foods purchased by 2.5% (−0.142 FSA points). Nutri-Score’s performance improved with the variance (but not the mean) of the nutritional quality of the category. In-store surveys suggest that Nutri-Score’s ability to attract attention and help shoppers rank products by nutritional quality may explain its performance.

Texte intégralRésumé :
Abstract Objectives The use of grocery store tours to provide nutrition education has increased in popularity. Participants in these tours can accompany a nutrition professional as they walk through a grocery store and receive information about products and their nutritional quality. However, there are several obstacles to this approach being more widely used. The objective of this ongoing research project is to show that people find virtual worlds to be acceptable, to determine the most effective method of delivering nutrition education virtually and to determine if people find information provided by an avatar to be credible. Methods An innovative technological approach is to create 3D virtual supermarkets that can be used to deliver nutrition information. We have created a 3D virtual supermarket where the viewer is provided with relevant nutrition information by an avatar in different sections of a virtual supermarket (e.g., produce, dairy, meat or cereals). The avatar uses props such as nutritional information panels, photos or videos to help convey specific information. We are currently conducting a study where participants experience a virtual grocery store tour using three different electronic mediums: handheld tablet, PC monitor or VR-HMD. After being randomized to a treatment order, the participant reports to the laboratory on three occasions. On reporting to the laboratory, the participant has a sensor attached to their wrist to measure heart rate, heart rate variability, skin conductance and skin temperature (to determine if there are physiological differences between the different mediums). They then remain seated quietly for ten minutes while baseline measures are taken. The participant then observes the store tour through the relevant medium. After the completion of the tour, the participant completes a questionnaire about their experiences of the tour. Results This is a study protocol and results are currently being collected. Conclusions This study will provide new information regarding an innovative approach to providing nutrition education. Funding Sources This project received no funding.

Texte intégralRésumé :
Simulated online grocery store platforms are innovative tools for studying nutrition-related policies and point-of-selection/point-of-purchase interventions in online retail settings, yet there is no clear guidance on how to develop these platforms for experimental research. Thus, we created a standardized guide for the development of an online grocery store, including a detailed description of (1) methods for acquiring and cleaning online grocery store data, and (2) how to design a two-dimensional online grocery store experimental platform. We provide guidance on how to address product categorization, product order/sorting and product details, including how to identify outliers and conflicting nutritional information and methods for standardizing prices. We also provide details regarding our process of “tagging” food items that can be leveraged by future studies examining policies and point-of-selection/point-of-purchase interventions targeting red and processed meat and fruits and vegetables. We experienced several challenges, including obtaining accurate and up-to-date product information and images, and accounting for the presence of store-brand products. Regardless, the methodology described herein will enable researchers to examine the effects of a wide array of nutrition-related policies and interventions on food purchasing behaviors in online retail settings, and can be used as a template for reporting procedures in future research.

Texte intégralRésumé :
The rising prevalence of non-communicable diseases has brought attention to the importance of consuming a healthy diet. One strategy to improve diet quality is through front-of-pack (FOP) nutrition labels. Taking advantage of an online grocery store, we allowed consumers to choose the FOP labels they preferred, and combined this information with real-time feedback on the overall nutritional quality of the shopping basket. We hypothesized that these dynamic food labels with real-time feedback (DFLF) would improve nutritional quality of food purchases. This trial followed a two-arm (no-label control and DFLF) crossover design with 125 participants exposed to each condition once in random order via an online grocery store. A first difference regression model allowed for estimating the unbiased effect of the DFLF on diet quality, measured by the weighted average Nutri-Score (ranging 1 to 5) per serving (primary) and changes in select nutrients and calories. The mean weighted Nutri-Score was 0.4 (12.6%) higher in the DFLF arm (CI: [0.2, 0.6]) relative to the control. The DFLF also decreased the amount of sugar per serving by 0.9 g (CI: [−1.7, −0.0]) and total sugar per shop by 169.5 g (CI: [−284.5, −54.5]). The DFLF features significantly improved nutrition quality relative to no labelling, as measured by average Nutri-Score values. These results shed light on the considerable potential of the online shopping environment to improve diet quality through customization and real time feedback.

Abstract Backgroung/Objectives: Compares the nutritional quality of pre-packaged foods carrying health-related claims with foods that do not carry health-related claims. Subject/Methods: Cross-sectional survey of pre-packaged foods available in Germany, The Netherlands, Spain, Slovenia and the United Kingdom in 2013. A total of 2034 foods were randomly sampled from three food store types (a supermarket, a neighbourhood store and a discounter). Nutritional information was taken from nutrient declarations present on food labels and assessed through a comparison of mean levels, regression analyses and the application of a nutrient profile model currently used to regulate health claims in Australia and New Zealand (Food Standards Australia New Zealand’s Nutrient Profiling Scoring Criterion, FSANZ NPSC). Results: Foods carrying health claims had, on average, lower levels, per 100 g, of the following nutrients, energy—29.3 kcal (P<0.05), protein—1.2 g (P<0.01), total sugars—3.1 g (P<0.05), saturated fat—2.4 g (P<0.001), and sodium—842 mg (P<0.001), and higher levels of fibre—0.8 g (P<0.001). A similar pattern was observed for foods carrying nutrition claims. Forty-three percent (confidence interval (CI) 41%, 45%) of foods passed the FSANZ NPSC, with foods carrying health claims more likely to pass (70%, CI 64%, 76%) than foods carrying nutrition claims (61%, CI 57%, 66%) or foods that did not carry either type of claim (36%, CI 34%, 38%). Conclusions: Foods carrying health-related claims have marginally better nutrition profiles than those that do not carry claims; these differences would be increased if the FSANZ NPSC was used to regulate health-related claims. It is unclear whether these relatively small differences have significant impacts on health.

Texte intégralRésumé :
Nell'ultimo secolo, a grazie ai progressi compiuti dalla medicina, dalla sanità pubblica e dalle migliorate condizioni socio-economiche, la speranza di vita alla nascita è aumentata nei paesi ad alto reddito, Italia compresa, passando da 45 anni a più di 80 anni. L'invecchiamento è un fattore di rischio per malattie croniche che vengono erroneamente considerate una fase inevitabile dell'invecchiamento. L'aumento della prevalenza di queste malattie in giovane età significa che sono anche legate a uno stile di vita inadeguato. A questo proposito, la riduzione dei fattori di rischio per alcune malattie croniche può portare ad una significativa riduzione del rischio di svilupparle. La prevalenza del deterioramento cognitivo aumenta con l'età e in un terzo dei casi peggiora fino alla demenza che è una condizione altamente invalidante associata ad alti costi sanitari e sociali. Dal punto di vista della salute pubblica, è di primaria importanza cercare di prevenire o posticipare l'insorgenza del declino cognitivo e cercare di rallentare la sua progressione verso la demenza. Dato che nessun trattamento farmacologico può prevenire o ritardare il deterioramento cognitivo e la demenza, è obbligatorio cercare di intervenire su fattori di rischio modificabili, come l'alimentazione. Lo stress ossidativo sembra giocare un ruolo chiave nella patogenesi del declino cognitivo e della demenza. Obiettivo del lavoro svolto durante il dottorato di ricerca è stato indagare il ruolo di fattori nutrizionali nel declino cognitivo associato all’invecchiamento. Particolare interesse è stato rivolto a nutrienti ad azione antiossidante come vitamina E e composti polifenolici. La vitamina E, in particolare l'α-tocoferolo, è una vitamina introdotta con la dieta ad alto potenziale antiossidante. Tuttavia, ci sono evidenze contrastanti in letteratura riguardo alla sua associazione con declino cognitivo e demenza. L’attività di dottorato è stata quindi finalizzata a verificare la presenza di un'associazione tra livelli plasmatici di vitamina E e deterioramento cognitivo, nella popolazione di anziani, non dementi al basale partecipanti allo studio InCHIANTI (Invecchiare In CHIANTI), seguiti per 17 anni. I risultati ottenuti hanno confermato la presenza di un'associazione tra il livello plasmatico di vitamina E e lo stato cognitivo: l'aumento di 10 µmol / L di vitamina E è stato associato ad una ridotta HR del deterioramento cognitivo del 20%. Inoltre, la ricerca è stata rivolta ad indagare il ruolo dei composti polifenolici introdotti con l’alimentazione sulle malattie croniche che possono essere fattori di rischio per il deterioramento cognitivo. Tale attività ha portato alla pubblicazione di una revisione sistematica intitolata “Systematic Review on Polyphenol Intake and Health Outcomes: Is there Sufficient Evidence to Define a Health-Promoting Polyphenol-Rich Dietary Pattern?”. I dati ottenuti hanno riportato l'associazione inversa tra l'assunzione di polifenoli e diversi outcome di rischio per la salute e le malattie. Tuttavia, a causa dell'elevata eterogeneità degli studi, non è stato possibile definire un range raccomandato di assunzione giornaliera di polifenoli. In conclusione, i risultati ottenuti hanno confermato il ruolo della dieta come fattore di rischio di declino cognitivo. Pertanto, è possibile raccomandare una dieta ricca in antiossidanti (vitamina E e polifenoli) come strategia preventiva al fine di promuovere un invecchiamento cognitivo in salute.In the last century, due to progresses made by medicine, public health and social-economic conditions, life expectancy at birth increased in high income countries, including Italy, from 45 years to more than 80 years. Aging is a risk factor for chronic diseases which are mistakenly considered an unavoidable stage of aging. The increase in the prevalence of these diseases at a young age means that they are also related to an inadequate lifestyle. In this regard, the reduction of risk factors for certain chronic diseases can lead to a significant reduction in the risk of developing them. The prevalence of cognitive impairment increases with age, and in one third of the cases, it worsens to dementia which is a highly disabling condition associated with high healthcare and society costs. From a public health perspective, it is of primary importance to try to prevent or postpone the onset of cognitive decline and to try to slow its progression to dementia. Given that no pharmacologic treatment can prevent or delay cognitive impairment and dementia, it is mandatory try to intervene on modifiable risk factors, such as nutrition. Oxidative stress appears to play a key role in the pathogenesis of cognitive decline and dementia. The aim of the work carried out during the PhD was to investigate the role of nutritional factors in the cognitive decline associated with aging. Particular interest was addressed to nutrients with antioxidant action such as vitamin E and polyphenolic compounds. Vitamin E, in particular α-tocopherol, is a vitamin introduced with the diet with high antioxidant potential. However, there are conflicting evidences in the literature regarding its association with cognitive decline and dementia. The PhD activity was therefore aimed at verifying the presence of an association between plasma levels of vitamin E and cognitive impairment, in the older adult population, not demented at baseline, participating in the InCHIANTI study (Aging In CHIANTI area), followed for up to 17 years. Our results confirmed the presence of an association between plasma vitamin E level and cognitive status: the increase of 10 µmol / L of vitamin E was associated with a reduced HR of cognitive impairment by 20%. In addition, the research activity carried out was aimed at investigating the role of polyphenol introduced with the diet on chronic diseases that can be risk factors for cognitive impairment. This activity led to the publication of a systematic review entitled “Systematic Review on Polyphenol Intake and Health Outcomes: Is there Sufficient Evidence to Define a Health-Promoting Polyphenol-Rich Dietary Pattern?” which focuses on another important antioxidant, polyphenols, and chronic diseases which can be risk factors for cognitive impairment. In this review we reported the inverse association between polyphenols intake, and several outcomes of health and diseases risk. Because to the high heterogeneity of the studies, it was not possible to define a recommended range of daily polyphenol intake. In conclusion, the results obtained confirmed the role of diet as a risk factor for cognitive impairment. Therefore, it is possible to recommend a diet rich in antioxidants (vitamin E and polyphenols) as a preventive strategy to promote healthy cognitive aging.

CAVALLARO, VIVIANA. « SULFUR NUTRITION AND PARTITIONING IN RICE UNDER DIFFERENT STRESS CONDITIONS ». Doctoral thesis, Università degli Studi di Milano, 2021. http://hdl.handle.net/2434/881847.
Texte intégralRésumé :
Sulfur (S) is an essential macronutrient required by plants for their correct development. This element is fundamental for the biosynthesis of different compounds, such as the two amino acids, cysteine (Cys) and methionine (Met), vitamins (biotin and thiamine), peptides involved in the response to abiotic stresses (glutathione - GSH, and phytochelatines - PCs), lipids and co-factors. Sulfate (SO42-) is the main S form taken up from soil by root system and then assimilated inside the cells during the sulfur reductive pathway. The uptake and the systemic movements of this anion are accomplished by the SULfate TRansporter (SULTR) gene family, which encode for H+/SO42- membrane co-transporters with different localization, amino acidic sequences, and affinity to sulfate. Since has been demonstrated that S has a key role in the response to different abiotic stresses (such as sulfur deficiency, heavy metal exposure or salt stress), the expression of these genes must be finely regulated, according to the different environmental conditions and requests for S reduced compounds.
The general aim of the present thesis is the description of S systemic fluxes in rice in different stress conditions, to obtain more information about the contribution of S in determining plant tolerance to abiotic stresses. To achieve the goal, we also took advantage of analysis performed with an elemental analyzer coupled with an isotope ratio mass spectrometer (EA-IRMS), a powerful instrument which utilizes stable isotopes of elements as tracers.
The entire research has been divided in three different parts.
In the first work, potential 32S/34S isotope effects occurring during SO42- uptake were investigated in a closed hydroponic system in which a limited amount of substrate (SO42- in the nutrient solution) was continuously removed from the solution by the activity of the sulfate transporters of the root and converted in a final product (total S of the plant). An isotope discrimination against 34S occurred during SO42- uptake: plants had a lighter S isotope composition, and the residual SO42- in the hydroponic solution was enriched in heavy stable isotope. Fractionation during uptake showed two phases characterized by different fractionation factors, reflecting changes in the expression of the OsSULTR deputed to the root uptake which may explain the different isotope phenotypes observed during plant sulfate acquisition. Moreover, the possible 32S/34S isotope effects associated to both S partitioning and metabolism were investigated by comparing plants pre-grown in complete nutrient solutions and then continuously maintained on media containing SO42- (steady-state) or deprived of SO42- for 72h. The SO42- pool of the steady-state shoot was significantly 32S depleted with respect to the SO42- pools of root, while the organic S (Sorg) pools were significantly depleted in 34S compared to both the SO42- pool of both the organs and the S source. These results suggested a higher S assimilation in the aerial part of plants which favor the lighter isotope. Under S starvation, S assimilation progressively enriched the Sorg pools in the lighter 32S isotope and the residual SO42- in both the organs in the heavier 34S isotope. Most pronounced isotope separations were again observed in the shoot, confirming the prominent role of this organ in SO42- assimilation and S allocation. No fractionation due to translocation activity was observed.
In the second part of the work, to validate the results previously obtained, we performed a mass balance study in rice plants exposed for 72h to different Cd concentrations, to investigate possible changes in S stable isotope fractionation due to this stress: in fact, adaptation of S metabolism has a pivotal role in responses to heavy metal exposure. As expected, Cd treatment strongly enhanced SO42- uptake and assimilation, as indicated by the analyses of the S pools (Stot, SO42-, and Sorg). S isotope analyses performed on the whole plants revealed changes in the S metabolism associated to variations in the discrimination against 34S, which was less evident as Cd concentration in the external medium increased. Transcriptional analysis suggested again that change of the ratio between relative transcripts of OsSULTR1;1 and OsSULTR1;2, as observed for S starvation, may be responsible for the progressive decreased in 34S isotope discrimination. The important role of shoot in S assimilation was confirmed: isotope fractionation associated to sulfate assimilation was higher in shoot than in root, and progressively increased as Cd concentration did.
The last part of work was focused on fully characterize, under hydroponics-controlled conditions in the absence or in the presence of salt stress (80 mM NaCl), the phenotypic behavior in the already available salt tolerant introgression line (IL) Onice 11 (O11), obtained by Marker-Assisted Back-Cross (MABC) selection starting from the cross between the Italian japonica elite cultivars Onice (sensitive recurrent parent) and the indica variety IR64-SalTol (tolerant), donor of the major QTL SalTol. Moreover, S acquisition and metabolism of O11 and both the parental lines were evaluated to investigate their possible implication in determining the different tolerance to salt stress. Results showed the beneficial effect of the introgression of the SalTol QTL from the indica variety into selected japonica rice line, based on different characteristics of selected phenotypic-biochemical-physiological parameters. However, salt stress strongly affected S uptake and assimilation, and we can reasonably suppose that these features do not justify the different salt tolerance in the considered IL O11.
In conclusions, rice plants can discriminate against 34S during SO42- uptake and assimilation. Between plants organs, shoot represents the predominant one involved in S assimilation. Abiotic stresses, such as S starvation or Cd exposure, lead to changes in the ratio of relative transcripts between the OsSULTRs involved in the uptake of sulfate, and this may be the cause of the different isotope phenotypes observed. Finally, salt tolerance in the IL O11 appears to not be dependent on different S metabolism.

Texte intégralRésumé :
Negli ultimi secoli, l'aspettativa di vita è aumentata grazie a uno stile di vita migliore, ma di conseguenza sono aumentate le patologie legate all'invecchiamento. L'invecchiamento è un processo fisiologico complesso e modificazioni legate all'età sono evidenti anatomicamente e fisiologicamente nella BEE. L'accumulo di danno ossidativo alle macromolecole da parte di RONS e ROS in BEE può essere cruciale nello sviluppo e nella progressione di diverse patologie del SNC.
In questa situazione l'ischemia cerebrale potrebbe alterare ulteriormente l'equilibrio ossidante/antiossidante a favore degli ossidanti.
In questo scenario, l'alimentazione può contrastare gli impatti ossidativi e le diete arricchite di polifenoli possono fornire effetti benefici.
Il caffè è stato descritto come una fonte molto importante di composti antiossidanti (Ricci A. et al., 2018), ma la sua lavorazione produce ogni anno grosse quantità di scarto (Mussatto et al., 2011).
Seguendo queste linee guida, lo scopo di questo studio era di valutare le proprietà antiossidanti di diversi composti correlati al caffè, da soli e combinati insieme, in un modello in vitro di ischemia.
I composti utilizzati sono stati: fitoestratti derivanti dagli scarti della produzione del caffè e arricchiti in specifici componenti polifenolici; e metaboliti del caffè individuati nel plasma di persone che bevono caffè.
Il momento successivo alla riossigenazione provoca un aumento dei ROS, raggiungendo un picco massimo entro 1h dal ripristino delle normali condizioni di coltura (Adibhatla RM et al., 2001). Pertanto, per la valutazione delle proprietà antiossidanti dopo OGD, come condizione di maggior stress è stato scelto l'intervallo 0-1h immediatamente successivo al recupero.
Quindi, al fine di valutare le proprietà antiossidanti dei composti del caffè in OGD, sono state effettuate valutazioni sullo stato di fosforilazione delle chinasi Erk e Akt, che se attive promuovono la migrazione di Nrf2 nel nucleo, sui livelli della proteina Nrf2 e sulla sua distribuzione intracellulare, ed infine sui livelli proteici di HO-1, come una dei suoi geni bersaglio. Inoltre, è stata valutata anche la proteina Hsp70, che è coinvolta nel controllo del ripiegamento delle proteine ed infine, è stata misurata la produzione di malondialdeide (MDA) 24 ore dopo il recupero come marker di perossidazione lipidica.
I risultati hanno dimostrato la capacità dei composti correlati al caffè di riuscire ad attivare la via di segnalazione Nrf2 in modo diverso e che solo i metaboliti modulavano positivamente Hsp70.
I risultati dell'MDA hanno suggerito che la presenza dei composti antiossidanti, testati da soli o combinati, aveva avuto un effetto positivo sulla sua modulazione.
I risultati, quindi, hanno dimostrato le proprietà antiossidanti dei fitoestratti e dei metaboliti specifici del caffè, suggerendo che le sostanze stimolano la risposta antiossidante attivando diverse vie, che combinate insieme potrebbero potenziare la difesa antiossidante.
L'effetto antiossidante dei metaboliti potrebbe indicare che l'assunzione moderata di caffè giornaliera in soggetti anziani esposti all'invecchiamento e maggior rischio di insulto ischemico, potrebbe contribuire alla riduzione dello stress ossidativo limitando il danno da riperfusione in caso di attacchi ischemici.
Queste difese potrebbero essere aumentate attraverso i fitoestratti derivati dal caffè ingeriti come integratori alimentari. Il riutilizzo di questa biomassa di scarto, avrebbe un impatto positivo sia sull'economia che sull'ecosistema, in quanto ridurrebbe notevolmente l'inquinamento.Nowadays, the people get older and older thanks to a better life-style, but consequently, carrying on pathologies typical of the old age, included aging. The aging is a complex physiological process and age-related changes are evident anatomically and physiologically in the BBB. The accumulation of oxidative damage to macromolecules by RONS and ROS in BBB can be crucial in the development and progression of different CNS pathologies. In this situation, cerebral ischemia could further alter the oxidant/antioxidant balance in favour of oxidants. In this scenario, nutrition can counteract the oxidative impacts, polyphenol-enriched diets can provide beneficial effects, preventing cognitive decline and degenerative disorders. More recently, coffee has been described as a very important source of antioxidant compounds (Ricci A. et al., 2018) but its production generates large amount of waste. According to these guidelines, the aim of this study was to evaluate the antioxidant properties of several coffee-related compounds alone and combined together in an in vitro model of ischemia. The compounds used were: phytoextracts deriving from the waste of coffee production and enriched in specific polyphenolic components; and coffee metabolites found in plasma of people drinking coffee. The moment after reoxygenation causes a considerable increase in ROS, reaching a maximum peak within 1 hour of the restoration of normal culture conditions (Adibhatla RM et al., 2001). Therefore, for the evaluation of the antioxidant properties after OGD, the time span 0-1h immediately following recovery was chosen as the condition of greatest stress. Therefore, in order to evaluate the antioxidant properties of the coffee compound under OGD, the antioxidant pathway Nrf2 was analyzed within 0-1h, immediately following recovery. Evaluations were performed on the state of phosphorylation of Erk and Akt kinases, which if active promote Nrf2 migration in the nucleus, on the levels of the Nrf2 protein and on its intracellular distribution, and finally on the protein levels of HO-1, as one of its genes target. Furthermore, the protein Hsp70, which is involved in the control of protein folding, was also evaluated. Finally, malondialdehyde (MDA) production was measured as a marker of lipid peroxidation 24 hours after recovery. The results suggested the ability of coffee-related compounds to activate the Nrf2 signaling pathway differently and only the pre-treatment with metabolites modulated positively Hsp70. MDA results suggested that the presence of the antioxidant compounds, tested alone or combined, had a positive effect on its modulation. The results showed the antioxidant properties of phytoextracts and specific coffee metabolites, suggesting that the substances stimulate the antioxidant response by activating different pathways, which combined together in the mix, could enhance antioxidant defense. The antioxidant effect of coffee metabolites could indicate that the moderate intake of coffee every day in elderly subjects exposed to aging and greater risk of ischemic insult, could contribute to the reduction of oxidative stress by limiting reperfusion damage in the case of ischemic attacks. These defenses could be increased through the phytoextracts derived from coffee ingested as food supplements. The reuse of this waste biomass, would have a positive impact on both the economy and the ecosystem, as it would significantly reduce pollution.

Hall, Elizabeth. « The Effects of a Supermarket Tour on Improvement of Nutrition Knowledge and Eating Behavior ». Digital Commons @ East Tennessee State University, 2017. https://dc.etsu.edu/etd/3333.
Texte intégralRésumé :
The purpose of this study was to determine if participation in a supermarket tour improves nutrition knowledge and eating behavior in adult participants. Participants were recruited in communities surrounding Food City stores, a local supermarket. Prior to completing a standardized tour, participants completed a survey to assess nutrition knowledge and eating behavior. This survey was given to participants again three months later. A program evaluation was given one time at the end of the tour. Data analysis revealed no significant findings, other than the behavior-based question: “How many meals or snacks on most days included vegetables”. Vegetable consumption appeared to decrease. All participants who completed the program evaluation reported they learned something new as a result of the tour and were satisfied with the experience. These findings suggest that nutrition education provided in supermarkets is well-received by participants, but additional research with objective measures is needed.

Texte intégralRésumé :
Supplemental Nutrition Assistance Program (SNAP)-authorized store environments could be improved to favor consumer purchase of healthy products. Engaging with the key intermediaries who can use marketing-mix and choice-architecture (MMCA) strategies to encourage low-income consumers to purchase healthy products aligned with the Dietary Guidelines for Americans (DGA), 2015-2020 is essential. This PhD research describes five investigations that explored the perspectives of food store owners, managers, and corporate or independent businesses (e.g., retailers) to inform healthy food retail approaches: (1) a systematic review of the literature (1980-2017) identified social-ecological influencers of food store retailers' decision-making and ability to use MMCA strategies to encourage healthy dietary purchases in the United States (US); (2) SNAP-authorized retailers' perceived feasibility and costs to implement healthy MMCA strategies in rural stores were assessed (n=29); (3) SNAP-authorized retailers' healthy food and beverage perceptions and DGA-aligned product offerings were documented; (4) prevalent SNAP-authorized food store retailers in the US and between two states were identified to inform settings where healthy food retail approaches could reach numerous SNAP consumers; (5) and the availability of corporate social responsibility commitments to use MMCA strategies to improve consumers' diet quality among prevalent SNAP-authorized food store chains was explored. The collective findings from the review and four studies were that multiple social-ecological factors (e.g., skills/knowledge, consumers, suppliers) influenced US retailers' decision-making and ability to use MMCA strategies that favor healthy products. Rural retailers perceived prompting and proximity (e.g., labeling and location) strategies as feasible and less costly compared to other MMCA strategies. Some misalignments of healthy food perceptions and food store availability were identified and indicated a need for trainings to enhance the success of healthy food retail programs. To reach numerous SNAP consumers, healthy food retail programs should target nontraditional (e.g., non-grocery) food stores with varied approaches by state. However, few prevalent SNAP-authorized retailers have made public, voluntary commitments to reduce obesity and may reflect a low readiness to engage in partnerships to establish healthy food retail environments. Future research should document approach to and the impact of using MMCA strategies to encourage healthier consumer purchases on business outcomes among diverse store contexts.Doctor of Philosophy

Anderson, Anjenique. « Food Store Audits : Examining Food Price, Availability, and Quailty, Before and After Relocation of Public Housing Residents ». Digital Archive @ GSU, 2010. http://digitalarchive.gsu.edu/nutrition_theses/21.
Texte intégralRésumé :
In an effort to deconcentrate poverty, Atlanta is attempting to become the first city in the U.S. to completely eliminate public housing by relocating ≈ 10,000 residents. Research has shown that the health status of public housing residents is worse than any other population. Evidence also suggests that there is an inverse relationship between neighborhood availability of healthy, affordable foods and diet intake. The aim of this study was to compare the price, availability, and quality of food items in the public housing residents’ communities, before and after relocation. Using Nutrition Environment Measures Survey (NEMS), a total of 42 food store audits were conducted in pre- and post-relocation neighborhoods. The prices in post-relocation middle chain grocery stores were significantly cheaper for total frozen dinners (p = 0.042), baked goods (p = 0.017), and potato chips (p = 0.035). There were no significant differences in produce quality. However, fruits (p <0>.001), vegetables (p < 0.001), lower fat milk (p < 0.001), whole milk (p =0.041), ground beef (p < 0 .001), reduced-fat hot dogs (p = 0.015), regular hot dogs (p < 0.001), frozen dinners (p < 0.001), low-fat baked goods (p < 0.001), whole-wheat bread (p <0 .001) and 100% juice (p < 0.001) were more available in middle chain grocery stores than convenience stores. These results suggest that public housing residents have relocated to a food environment that is similar to their previous environment. Relocation of public housing residence did not have a significant effect on their access to food.

Texte intégralRésumé :
Food intake is sporadic and, in many cultures, occurs in three daily boluses. At the same time, energy expenditure is continuous and can vary to a large extent independently of the pattern of energy intake, although fixed or predictable demands (e.g. through occupation) means that in most persons food intake and energy expenditure are soon balanced. The body has developed complex systems that direct excess nutrients into storage pools; as they are needed, they also regulate the mobilization of nutrients from these pools. Carbohydrate, lipid, and protein (the latter a source of amino acids) are the three types of energy supply that are stored variably and assimilated from food each day. That we can carry on our daily lives without thinking about whether to store or mobilize fuels, and which to use, attests to the remarkable efficiency and refinement of these systems of metabolic control.

Texte intégralRésumé :
This chapter presents an overview of restrictive covenants as a corporate real estate practice that places conditions on land use, such as prohibiting the sale of food or prohibiting the development of grocery stores. Restrictive covenants are a significant barrier to establishing a new store in older neighbourhoods and the consequences are interconnected: when food stores act as anchors in a community shopping area, their closure can lead to a loss of neighbourhood-level identity and history. Rectifying existing nutrition deserts is much harder than preventing new ones. Alternative food systems are needed and should support urban agriculture, urban greenhouses and cooperative food store models, incentivise the development of mobile healthy food vending, and offer tax abatements or subsidies for healthy food retail in low-income nutrition desert neighbourhoods. Government support is needed to limit restrictive covenants and develop alternative food channels through various creative means.

Texte intégralRésumé :
Food intake is sporadic: for most people it occurs in three major boluses each day. Energy expenditure, however, is continuous, with variations during the day that bear no resemblance to the pattern of energy intake, except that over some reasonable period of time (a week or more) the two will, in most people, match almost exactly. Therefore the body has developed complex systems that direct nutrients into storage pools when they are in excess, and that regulate the mobilization of nutrients from these pools as they are needed. The situation is analogous to the fuel tank of a car and the throttle that regulates fuel oxidation, except that in the car there is just one fuel and just one engine: in humans there are three major nutrients and a variety of tissues and organs, each of which may have its own preferences for fuels, that vary with time. Carbohydrate, fat, and protein (made up of amino acids), are the three sources of energy which are variably stored and assimilated from food each day. The fact that we can carry on our daily lives without thinking about whether to store or mobilize fuels, and which to use, attests to the remarkable efficiency of these control systems....

Texte intégralRésumé :
Strawberry is a fruit with a short season of harvest. Strawberry is well-known among people all over the world for its distinct flavour, nutritional value, and delicacy. While on the other hand, preserving strawberry and shelf life extension has been a huge difficulty due to their perishable nature. Making effective and sustainable use of already available food processing and preservation technology needs time. Researchers must use advanced techniques like a cool store, modified atmospheric packaging (MAP), cool store, controlled atmospheric storage (CA), various packaging methods, and a variety of chemical and physical treatments to retain commodities for a longer period due to strategic market sales following harvest. Except for the preserving techniques, there is some polysaccharide-based edible coating which has a crucial role in delaying fruit softening, fruit decay, maintaining the increased levels of ascorbic acid and phenols, enhancing the activities of antioxidant enzymes, and reducing membrane damage. During the postharvest stages, there are numerous threats to keep in view regarding the safety and quality of strawberries. In this chapter, we will discuss the benefits and drawbacks of some of the various preservation technologies, as well as how they might be utilised to preserve and a prolonged period of freshly harvested strawberries.

Texte intégralRésumé :
In this chapter we will look briefly at the prevention needs of people with disabilities and people who are vulnerable and require special care dental services for reasons that may be social. Within this group there will be a spectrum of people with needs and dependencies. Not everyone described as belonging to a vulnerable group in this chapter would identify themselves as disabled; nevertheless, what they have in common are a range of factors that put their oral health at risk, make accessing dental care complicated, or make the provision of dental care complicated. These factors may include a ‘physical, sensory, intellectual, mental, medical, emotional or social impairment or disability, or more often a combination of these factors’ (GDC 2012). People with disabilities have fewer teeth, more untreated disease, and more periodontal disease when compared to the general population in the UK (Department of Health 2007). Good oral health can contribute to better communication, nutrition, self-esteem, and reduction in pain and discomfort, while poor oral health can lead to pain, discomfort, communication difficulties, nutritional problems, and social exclusion (Department of Health 2007). As discussed in previous chapters, the important risk factors for oral diseases include: high-sugar diets, poor oral hygiene, smoking, and alcohol misuse. They are also shared risk factors for chronic non-communicable diseases such as respiratory diseases, cardiovascular diseases, diabetes, and cancers. The basic principles and approaches for the prevention of oral diseases in disabled people and vulnerable groups are similar to those described in previous chapters; however, there is a need to recognize that the context, the circumstances, the settings, and the opportunities for prevention will be slightly different, depending on the groups. For example, some disabled people (e.g. people with learning disabilities) may be reliant on others, such as family, carers, health care workers, to support basic self-care and to access health services. Other vulnerable groups such as homeless people live independent lives but lack access to basic facilities such as drinking water, and a place to store toothbrushes and toothpaste.

Texte intégralRésumé :
Since the agricultural revolution, traditional fermented beers served social and dietary functions, including hydration. There are longstanding customs of producing, consuming, and socializing with home-made beers. However, because they are time- and labour-intensive to produce, shifts away from traditional beers often occur with the introduction of market alcohols, which may not fulfil the dietary functions of traditional beers. This paper uses nine years of longitudinal data from 963 Tsimane’ Bolivian forager-horticulturalist adults to examine how the consumption of chicha, a traditional fermented beer, and market alcohol changed during a period of increased market integration from 2002 to 2010. It then uses cross-sectional dietary recall data with 45 adults to estimate chicha contributions to water intake. Our findings suggest that chicha consumption has decreased over time for women but not men. Chicha consumption, while more common, was strongly predictive of market alcohol consumption. Chicha contributed 1 litre to water needs for men and 0.6 litre for women. The increased drive to produce cash crops may not only limit the availability of preferred crops for chicha but also reduce the amount of time available to spend making chicha. Alternatives for making water more palatable, such as adding store-bought water flavouring powders, could further reduce traditional chicha consumption thereby having potential implications on daily social life and ripple effects on nutrition and hydration.

Texte intégralRésumé :
This chapter talks about community gardens that serve as sites for both food production and community education. The Bronx Green-up (BGU) is an initiative of the New York Botanical Garden. The BGU provides the technical support and materials needed for community gardens to succeed. The Green Corps, run by the Cleveland Botanical Garden, introduces at-risk youth to organic farming methods and provides them with opportunities to learn about gardening, nutrition, and environmental issues. The Growing to Green program, from the Franklin Park Conservatory and Botanical Gardens, has helped start, strengthen, and sustain approximately three hundred community or school gardens in Ohio. The Sankofa Farm at Batram's Garden involves the youth to enable them to get to college. Reflecting on the case studies in the chapter, it is clear that moving a community from a failing to a healthy state requires the participation of multiple entities: municipal agencies, social service organizations, community activists, for-profit organizations, and cultural and religious institutions. Each can play a role in making fresh produce more available and more appealing to those living in food deserts. By involving low-income residents in growing their own food, such initiatives will also enable them to feel in control of their diet and not at the mercy of what is available at the corner store. As gardens spring up in previously underserved neighborhoods, communities experience the ripple effects of reduced vandalism, trash, petty crime, and loitering.

Texte intégralRésumé :
Fruit quality is determined by numerous genetic factors that affect taste, aroma, color, texture, nutritional value and shelf life. To unravel the genetic components involved in the metabolic pathways behind these traits, the major goal of the project was to identify novel genes that are involved in, or that regulate, these pathways using correlation analysis between genotype, metabolite and gene expression data. The original and specific research objectives were: (1) Collection of replicated fruit from a population of 96 RI lines derived from parents distinguished by great diversity in fruit development and quality phenotypes, (2) Phenotypic and metabolic profiling of mature fruit from all 96 RI lines and their parents, (3) 454 pyrosequencing of cDNA representing mRNA of mature fruit from each line to facilitate gene expression analysis based on relative EST abundance, (4) Development of a database modeled after an existing database developed for tomato introgression lines (ILs) to facilitate online data analysis by members of this project and by researchers around the world. The main functions of the database will be to store and present metabolite and gene expression data so that correlations can be drawn between variation in target traits or metabolites across the RI population members and variation in gene expression to identify candidate genes which may impact phenotypic and chemical traits of interest, (5) Selection of RI lines for segregation and/or hybridization (crosses) analysis to ascertain whether or not genes associated with traits through gene expression/metabolite correlation analysis are indeed contributors to said traits. The overall research strategy was to utilize an available recombinant inbred population of melon (Cucumis melo L.) derived from phenotypically diverse parents and for which over 800 molecular markers have been mapped for the association of metabolic trait and gene expression QTLs. Transcriptomic data were obtained by high throughput sequencing using the Illumina platform instead of the originally planned 454 platform. The change was due to the fast advancement and proven advantages of the Illumina platform, as explained in the first annual scientific report. Metabolic data were collected using both targeted (sugars, organic acids, carotenoids) and non-targeted metabolomics analysis methodologies. Genes whose expression patterns were associated with variation of particular metabolites or fruit quality traits represent candidates for the molecular mechanisms that underlie them. Candidate genes that may encode enzymes catalyzingbiosynthetic steps in the production of volatile compounds of interest, downstream catabolic processes of aromatic amino acids and regulatory genes were selected and are in the process of functional analyses. Several of these are genes represent unanticipated effectors of compound accumulation that could not be identified using traditional approaches. According to the original plan, the Cucurbit Genomics Network (http://www.icugi.org/), developed through an earlier BARD project (IS-3333-02), was expanded to serve as a public portal for the extensive metabolomics and transcriptomic data resulting from the current project. Importantly, this database was also expanded to include genomic and metabolomic resources of all the cucurbit crops, including genomes of cucumber and watermelon, EST collections, genetic maps, metabolite data and additional information. In addition, the database provides tools enabling researchers to identify genes, the expression patterns of which correlate with traits of interest. The project has significantly expanded the existing EST resource for melon and provides new molecular tools for marker-assisted selection. This information will be opened to the public by the end of 2013, upon the first publication describing the transcriptomic and metabolomics resources developed through the project. In addition, well-characterized RI lines are available to enable targeted breeding for genes of interest. Segregation of the RI lines for specific metabolites of interest has been shown, demonstrating the utility in these lines and our new molecular and metabolic data as a basis for selection targeting specific flavor, quality, nutritional and/or defensive compounds. To summarize, all the specific goals of the project have been achieved and in many cases exceeded. Large scale trascriptomic and metabolomic resources have been developed for melon and will soon become available to the community. The usefulness of these has been validated. A number of novel genes involved in fruit ripening have been selected and are currently being functionally analyzed. We thus fully addressed our obligations to the project. In our view, however, the potential value of the project outcomes as ultimately manifested may be far greater than originally anticipated. The resources developed and expanded under this project, and the tools created for using them will enable us, and others, to continue to employ resulting data and discoveries in future studies with benefits both in basic and applied agricultural - scientific research.
