Several studies have focused on examining if breakfast habits have any short-term effects on school attendance, academic achievement, and general health in children and adolescents. Informed decisions of whether to promote eating breakfast or not require a more long-term perspective.</p> <p><strong>Objective</strong>: The aim of this study was to conduct a systematic review of scientific publications studying the effects identified as potentially relevant for the economic evaluation of eating breakfast in children and adolescents.</p> <p><strong>Design</strong>: A systematic literature review was conducted. Studies were identified by searching the electronic databases PubMed, CINAHL, Web of Science, and PsycINFO between January 2000 and October 2017. The inclusion criteria applied were published articles from peer-reviewed journals with full text in English, quantitative studies collecting primary data with school-aged children, and adolescents aged from 6 to 18 years as participants, performed entirely or partly in countries with advanced economies, except Japan and Taiwan.</p> <p><strong>Results</strong>: Twenty-six studies fulfilled the inclusion criteria, and studies that were judged to be of at least moderate quality were included in the analysis. The results of the review of eating breakfast studies showed positive and conclusive effects on cognitive performance, academic achievement, quality of life, well-being and on morbidity risk factors.</p> <p><strong>Conclusions</strong>: The overall assessment of the studies indicated positive effects of eating breakfast. How the identified effects influence societal costs and an individual’s quality-adjusted life years require further research.</p> 2019-09-12T07:48:00-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/1518 Role of intestinal microecology in the regulation of energy metabolism by dietary polyphenols and their metabolites 2019-02-14T05:14:00-08:00 Shaoling Lin shaoling.lin@fafu.edu.cn Zhengyu Wang shaoling.lin@fafu.edu.cn Ka-Lung Lam shaoling.lin@fafu.edu.cn Shaoxiao Zeng shaoling.lin@fafu.edu.cn Bee K. Tan shaoling.lin@fafu.edu.cn Jiamiao Hu shaoling.lin@fafu.edu.cn <p><strong>Background</strong>: Polyphenols are a class of plant secondary metabolites with a variety of physiological functions. Polyphenols and their intestinal metabolites could greatly affect host energy metabolism via multiple mechanisms.</p> <p><strong>Objective</strong>: The objective of this review was to elaborate the role of intestinal microecology in the regulatory effects of dietary polyphenols and their metabolites on energy metabolism.</p> <p><strong>Methods</strong>: In this review, we illustrated the potential mechanisms of energy metabolism regulated by the crosstalk between polyphenols and intestinal microecology including intestinal microbiota, intestinal epithelial cells, and mucosal immune system.</p> <p><strong>Results</strong>: Polyphenols can selectively regulate the growth of susceptible microorganisms (eg. reducing the ratio of Firmicutes to Bacteroides, promoting the growth of beneficial bacteria and inhibiting pathogenic bacteria) as well as alter bacterial enzyme activity. Moreover, polyphenols can influence the absorption and secretion of intestinal epithelial cells, and alter the intestinal mucosal immune system.</p> <p><strong>Conclusion</strong>: The intestinal microecology play a crucial role for the regulation of energy metabolism by dietary polyphenols.</p> 2019-02-14T04:18:29-08:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/3522 No correlation among expressed emotion, anxiety, stress and weight loss in patients with overweight and obesity 2019-10-09T01:08:04-07:00 Carla Gramaglia carla.gramaglia@gmail.com Eleonora Gattoni eleonoragattoni@yahoo.it Camilla Vecchi camillavecchi@yahoo.it Elisa Di Tullio elisaditullio@libero.it Giampaolo Biroli giampaolo.biroli@maggioreosp.novara.it Federico D'Andrea federico.dandrea@maggioreosp.novara.it Sergio Riso sergio.riso@maggioreosp.novara.it Maria Rosaria Gualano mgualano@unito.it Marco Marchetti marco.marchetti@unimol.it Marco Sarchiapone marco.sarchiapone@gmail.com Roberta Siliquini roberta.siliquini@unito.it Patrizia Zeppegno patrizia.zeppegno@med.uniupo.it <p><strong>Background</strong>: The onset of some types of obesity may correlate with specific familial relational patterns, and expressed emotion (EE), the family life’s ‘emotional temperature’, may play a role in obesity treatment compliance and outcome.</p> <p><strong>Objective</strong>: The aim of this study is to address the current gap in the literature about EE and obesity, assessing EE in a sample of patients with overweight or obesity and their relatives. A further objective is to assess patients’ weight loss, patients’ and relatives’ anxiety, perceived stress and their possible correlation with EE and diet compliance.</p> <p><strong>Design</strong>: A total of 220 patients with overweight or obesity and 126 relatives were recruited; their socio-demographic and clinical features were collected; and Level of Expressed Emotion Scale (LEE), State-Trait Anxiety Inventory 1 and 2 (STAI-Y1 and STAI-Y2) and Paykel Scale of Stressful Life Events were administered.</p> <p><strong>Results</strong>: Patients’ baseline body mass index (BMI) was negatively correlated with educational level, but we failed to find any correlation between BMI and the other variables assessed. We found a positive correlation between EE median and stressful life events, as well as between median EE and state and trait anxiety.</p> <p><strong>Conclusions</strong>: Our results seem to suggest that other factors than the psychological ones we investigated may play a role in treatment adherence and outcome in patients with overweight and obesity.</p> 2019-10-09T01:07:21-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/3422 Vegetable but not animal protein intake is associated to a better physical performance: a study on a general population sample of adults 2019-09-19T03:32:59-07:00 Diana Gazzani dd.gazzani@gmail.com Francesco Zamboni zambo987@libero.it Francesco Spelta francesco.spelta@univr.it Pietro Ferrari pietro.ferrari82@gmail.com Veronica Mattioli veronica.mattioli@univr.it Lucia Cazzoletti lucia.cazzoletti@univr.it Elisabetta Zanolin elisabetta.zanolin@univr.it Stefano Tardivo stefano.tardivo@univr.it Marcello Ferrari marcello.ferrari@univr.it <p><strong>Background</strong>: The research was conducted in the frame of a population-based, case control study, called Genes Environment Interaction in Respiratory Disease.</p> <p><strong>Objective</strong>: To assess the association between protein intake and physical performance in a general population sample.</p> <p><strong>Design</strong>: Researchers investigated the association between the participants’ dietary information and their physical performance using the 6-min walking test and the distance walked in metres (6MWD) as main outcome measure. Information on dietary intake was collected using the validated European Investigation into Cancer and Nutrition food frequency questionnaires (FFQs). Then, daily intake of energy and macronutrients was estimated by means of the NAF software (nutritional analysis of FFQ). Linear regression models were used to evaluate the associations between vegetable, animal and total protein intakes and the 6MWD. The models were adjusted for socio-demographic features, total fats and available carbohydrate intakes.</p> <p><strong>Results</strong>: The participants were 223 subjects (57% females) aged between 23 and 68 years. Their mean vegetable and animal proteins intake for gram/kg of body weight/day were, respectively, 0.4 and 0.7. After adjusting for all the potential confounders, there was a significant increase of 20.0 (95% CI 0.8; 39.2) m in the distance walked for an increase in 10 g/day of vegetable proteins and non-significant variations of −1.8 (95% CI −9.3; 5.7) m for an increase in 10 g/day of animal proteins and of 0.5 (95% CI −6.8; 7.7) for an increase in 10 g/day of total proteins. Discussion and conclusions: Our result suggests a positive role of vegetable proteins on physical performance. Whether this result is related to the high protein intake itself or may be a consequence of the other properties of plant-based foods deserves further investigation.</p> 2019-09-19T03:32:19-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/3418 Economic modeling for improved prediction of saving estimates in healthcare costs from consumption of healthy foods: the Mediterranean-style diet case study 2019-09-17T10:20:22-07:00 Jason P. H. Jones jasonjones@rti.org Mohammad M. H. Abdullah umabdul7@myumanitoba.ca Dallas Wood dwood@rti.org Peter J. H. Jones info@nfh.ca <p><strong>Background</strong>: By design, existing scenario-based nutrition economics studies on the financial benefits of healthy dietary behaviors generally report uncertainty in inputs and wide ranges of outcome estimates.</p> <p><strong>Objectives</strong>: This modeling exercise aimed to establish precision in prediction of the potential healthcare cost savings that would follow a reduction in the incidence of cardiovascular disease (CVD) consistent with an increase in adherence to a Mediterranean-style diet (MedDiet).</p> <p><strong>Design</strong>: Using a Monte Carlo simulation model on a cost-of-illness analysis assessing MedDiet adherence, CVD incidence reduction, and healthcare cost savings in the United States and Canada, short- and long-term cost savings that are likely to accrue to the American and Canadian healthcare systems were estimated using 20 and 80% increases in MedDiet adherence scenarios.</p> <p><strong>Results</strong>: Increasing percentage of population adhering to a MedDiet by 20% beyond the current adherence level produced annual savings in CVD-related costs of US$8.2 billion (95% confidence interval [CI], $7.5–$8.8 billion) in the United States and Can$0.32 billion (95% CI, $0.29–$0.34 billion) in Canada. An 80% increase in adherence resulted in savings equal to US$31 billion (95% CI, $28.6–$33.3 billion) and Can$1.2 billion (95% CI, $1.11–$1.30 billion) in each respective country.</p> <p><strong>Conclusion</strong>: Computational techniques with stochastic parameter inputs, such as the Monte Carlo simulation, could be an effective way of incorporating variability of modeling parameters in nutrition economics studies for improved precision in estimating the monetary value of healthy eating habits.</p> 2019-09-17T10:07:03-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/3601 <em>Rhus verniciflua</em> leaf extract suppresses obesity in high-fat diet-induced obese mice 2019-09-12T07:10:58-07:00 Kohei Suruga kouhei_suruga@kibun.co.jp Tsuyoshi Tomita t_tomita@kibun.co.jp Kazunari Kadokura kazunari_kadokura@kibun.co.jp Toshiro Arai tarai@nvlu.ac.jp <p><strong>Background</strong>: Obesity is a serious health problem in the world. We thought that the activity and safety of natural plants and/or foods are very important in the management of therapy for obesity. Rhus verniciflua (R. verniciflua) is also known as lacquer tree in Japan and Korea, and it is consumed as food ingredients and/ or traditional herbal medicine. We prepared an extract from R. verniciflua leaves (Rv-PEM01-99) to develop a new functional food material and/or nutritional supplements.</p> <p><strong>Objective</strong>: This study evaluated the anti-obesity effects of the Rv-PEM01-99 in high-fat diet (HFD)-induced obese mice.</p> <p><strong>Design</strong>: Six-week-old male C57BL/6J mice were divided into three groups: group I (HFD group), group II (HFD + 1% Rv-PEM01-99 group), and group III (HFD + 2% Rv-PEM01-99 group). Throughout the 56-day treatment period, body weights of these mice were checked twice a week. After 56 days, blood biochemical analyses were performed.</p> <p><strong>Results</strong>: In animal studies, no death or abnormalities in food consumption were observed between groups I, II, and III. Body weight gain in the groups administered Rv-PEM01-99 was less than that in group I. In particular, body weight gain in group III was significantly less than that in group I after 52 days of Rv-PEM01-99 administration. In addition, intra-abdominal fat and leptin levels in group III were significantly lower than those in group I. HPLC and LC/MS analysis showed a quercetin derivative as an active compound in Rv-PEM01-99.</p> <p><strong>Conclusion</strong>: Rv-PEM01-99, containing a quercetin derivative, showed anti-obesity effect in HFD-fed mice. It could therefore be useful as food material and/or nutritional supplement for management of obesity.</p> 2019-09-11T09:50:23-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/3553 Pholidonone, an active stilbene derivative from Pholidota cantonensis, exhibits pro-apoptotic effect via induction of endoplasmic reticulum stress in human gastric cancer 2019-09-06T03:49:34-07:00 Liang Liu enjoyyz@163.com Wei Wang enjoyyz@163.com Zhichen Zhao enjoyyz@163.com Chen Hu enjoyyz@163.com Li Tao enjoyyz@163.com Xianwen Zhang enjoyyz@163.com <p><em>Abstract</em></p> <p><strong><em>Backgroud:</em></strong> Gastric cancer (GC) has become the second leading cause of death due to the worldwide incidence, mortality and prevalence. Therefore, it is urgent to find new drugs with low toxicity and high efficacy for the treatment of gastric cancer. Natural products as well as functional foods have always been the rich source of potential antitumor agents. <em>Pholidota cantonensis </em>Rolfe, a well-known functional food and a folk medicine, has been used for a long time in China for inflammatory diseases. Previously, we have evaluated its possible antitumor potentials by screening different solvent extracts, and found that the ethyl acetate (EtOAc) extract showed much higher cytotoxicity on human GC cell line AGS with IC<sub>50</sub> value of 33.68 ± 1.68 μg/mL. In view of the poor knowledge concerning the phytochemical and pharmacological study of <em>P. cantonensis</em>, it is urgent to characterize the active compounds from EtOAc extract and the mechanisms of action underlying the anti-tumor effect of the herb.</p> <p><strong><em>Objective:</em></strong> This study aimed to identify the primary compounds in EtOAc extract of <em>P. cantonensis </em>involved in the antitumor activity of the plant by evaluating the cytotoxicity in two human GC cell lines including AGS and BGC-823 cells. Since endoplasmic reticulum (ER) stress-induced cell apoptosis represents attractive targets for cancer therapy recently, we focused on the underlying mechanisms associated with ER stress-induced cell apoptosis and related signaling pathways.</p> <p><strong><em>Methods: </em></strong>Various chromatographic techniques including silica gel, sephadex LH-20 and ODS C<sub>18 </sub>were used to separate the main active compound from EtOAc extract of <em>P. cantonensis</em>. The cell viability of AGS and BGC-823 cells upon purified compound treatment was determined by MTT assay. The alteration of cell morphology was observed using an inverted microscope. Cell apoptosis was determined by FITC-labeled annexin-V/PI double staining and flow cytometry analysis. Western blot analyses were performed to examine the levels of intracellular signaling molecules involved in ER stress-induced apoptosis.</p> <p><strong><em>Results: </em></strong>A rare stilbene derivative pholidonone was isolated and identified. The results showed that pholidonone displayed potent cytotoxicity on human gastric cancer cells. The IC<sub>50</sub> values for 24 and 48 h in AGS cells were 26.54 ± 0.32 and 25.20 ± 3.67 μM, and the IC<sub>50</sub> values for 24 and 48 h in BGC-823 cells were 32.41 ± 3.83 and 17.28 ± 2.30 μM, respectively). Additionally, pholidonone had pro-apoptotic effect on AGS and BGC-823 cells, and it dose-dependently up-regulated the levels of proteins involved in ER stress, including BiP, PDI, Calnexin, Ero1-Lα, IRE1α, PERK, CHOP and cleaved-caspase-3 in AGS and BGC-823 cells.</p> <p><strong><em>Conclusion:</em></strong> Pholidonone can trigger ER stress-induced apoptosis through PERK and IRE1α signaling pathway. Pholidonone might be a potential naturally occurred antitumor agent.</p> 2019-09-06T03:43:10-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/3504 Inclusion of microbe-derived antioxidant during pregnancy and lactation attenuates high-fat diet-induced hepatic oxidative stress, lipid disorders, and NLRP3 inflammasome in mother rats and offspring 2019-08-23T07:35:01-07:00 Zhen Luo luozhen0615@163.com Xue Xu xuxue1992@sjtu.edu.cn Sen Zhao zhaosen@sjtu.edu.cn Takami Sho jokersho@foxmail.com Wenli Luo 854751192@qq.com Jing Zhang zhangjing224@sjtu.edu.cn Weina Xu xuweina@sjtu.edu.cn Kong Hon chuangbo2001@126.com Jianxiong Xu jxxu1962@sjtu.edu.cn <p><strong>Objective</strong>: This study aimed to evaluate the effects of microbe-derived antioxidant (MA) on high-fat diet (HFD)-induced hepatic lipid disorders in mother rats and offspring.</p> <p><strong>Methods</strong>: A total of 36 female rats were randomly divided into three groups at the beginning of pregnancy: the control group (CG), HFD, and HFD with 2% MA. Mother rats were slaughtered at the first and 10th day of lactation (L1 and L10) and offspring were slaughtered at L10. The plasma and liver of mother rats, and liver of offspring were collected.</p> <p><strong>Results</strong>: The results showed that MA reversed HFD-induced activities of inducible nitric oxide synthase (iNOS) and antioxidative enzymes in liver of mother rats and offspring. In addition, MA reduced HFD-induced lipid accumulation through decreasing the low-density lipoprotein cholesterol (LDLC) content in plasma of mother rats and improving hepatic fatty acid synthase (FAS) in mother rats and offspring. MA decreased HFD-induced hepatic alkaline phosphatase (AKP) activity in liver of mother rats and offspring. Furthermore, MA reduced HFD-activated nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3) inflammasome in liver of mother rats and offspring.</p> <p><strong>Conclusions</strong>: MA supplementation reversed HFD-induced hepatic oxidative stress, lipid accumulation, NLRP3 inflammasome, and function in mother rats and offspring, suggesting MA can be functional ingredients to improve maternal-fetal health.</p> 2019-08-23T07:34:17-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/3361 Aronia berry extract inhibits TNF-α-induced vascular endothelial inflammation through the regulation of STAT3 2019-08-16T07:51:51-07:00 Tomomi Iwashima lovecook1028@gmail.com Yuki Kudome yuki_19900730@yahoo.co.jp Yoshimi Kishimoto kishimoto.yoshimi@ocha.ac.jp Emi Saita saita.emi@ocha.ac.jp Miori Tanaka g1670502@edu.cc.ocha.ac.jp Chie Taguchi taguchi.chie@ocha.ac.jp Satoshi Hirakawa sa-hirakawa@pola.co.jp Nobu Mitani n-mitani@pola.co.jp Kazuo Kondo kondo.kazuo@ocha.ac.jp Kaoruko Iida iida.kaoruko@ocha.ac.jp <p><strong>Background</strong>: Inflammation in endothelial cells induces production of inflammatory cytokines and monocytes adhesion, which are crucial events in the initiation of atherosclerosis. Aronia berry (Aronia meranocalpa), also called black chokeberry, contains abundant anthocyanins that have received considerable interest for their possible relations to vascular health.</p> <p><strong>Objective</strong>: The aim of this study was to investigate whether an anthocyanin-rich extract obtained from aronia berry can attenuate inflammatory responses in vascular endothelial cells.</p> <p><strong>Methods</strong>: As a model of vascular endothelial inflammation, human umbilical vein endothelial cells (HUVECs) pretreated with aronia berry extract were stimulated with tumor necrosis factor-alpha (TNF-α). The expression levels of cytokines and adhesion molecules were analyzed. To investigate the effects of aronia berry extract on the adhesion of THP-1 monocytic cell, the static adhesion assay was carried out. The possible molecular mechanisms by which aronia berry extract regulated vascular inflammatory responses were explored.</p> <p><strong>Results</strong>: The mRNA expressions of interleukins (IL-1β, IL-6, and IL-8) and monocyte chemoattractant protein-1 (MCP-1) upregulated by TNF-α were significantly suppressed by pretreatment with aronia berry extract. Aronia berry extract decreased TNF-α-induced monocyte/endothelial adhesion and suppressed vascular cell adhesion molecule-1 (VCAM-1) expression, but did not affect intercellular adhesion molecule-1 (ICAM-1) expression. Moreover, aronia berry extract decreased the phosphorylation of signal transducer and activator of transcription 3 (STAT3) and the nuclear levels of STAT3 and interferon regulatory transcription factor-1 (IRF1). The nuclear translocation of nuclear factor-kappa B (NF-κB) was not inhibited by aronia berry extract.</p> <p><strong>Conclusion</strong>: Aronia berry extract could exert anti-atherosclerotic effects on TNF-α-induced inflammation through inhibition of STAT3/IRF1 pathway in vascular endothelial cells.</p> 2019-08-16T07:51:14-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/1420 Establishment of comprehensive quality evaluation model of fresh instant rice 2019-07-22T12:09:02-07:00 Qinghong Meng mqh2018@yeah.net Shouwen Zhang hrbzsw@126.com Song Yan yansmm@yeah.net Zhihong Zhang zzhnm1982@sohu.com Liqun Wang wanglq2014@sina.com Yinglei Zhang zhangyl1984@sohu.com Haitao Guan ght1979@tom.com <p><strong>Background</strong>: Although the rice processing characteristics and processing quality evaluation technologies have been studied for many years in China, there have been few reports on the evaluation index system and evaluation method of fresh instant rice processing quality.</p> <p><strong>Objective</strong>: The aim of this study was to establish a comprehensive quality evaluation model of fresh instant rice to achieve the effective quantitative quality analysis.</p> <p><strong>Methods</strong>: A total of 108 japonica rice varieties were selected as the test samples, followed by the production of fresh instant rice. The color value, physicochemical quality, texture characteristic, and sensory quality of fresh instant rice were systematically analyzed. Difference analysis, correlation analysis, factor analysis, and cluster analysis were used to determine the representative quality indexes of fresh instant rice. Through initialization, forward, and normalization, the standardized indexes (0≤ Xi ≤1) were obtained. The discriminant matrix of the analytic hierarchy process (AHP) was used to confirm the weight (Wi) of each representative quality index, establishing the comprehensive quality evaluation model.</p> <p><strong>Results</strong>: The variable coefficients of 12 out of 17 quality indexes were more than 10%. There were 136 correlation coefficients, including 15 cases with a significant difference at the level of α = 0.05 and 52 cases with a significant difference at the level of α = 0.01. Five representative quality indexes of fresh instant rice were selected by factor analysis and cluster analysis, including palatability, adhesiveness, b* value, resilience, and iodine color value. And the comprehensive quality evaluation model of fresh instant rice integrating representative indexes was obtained: <em>Y</em> = 0.5650 × palatability + 0.2294 × adhesiveness + 0.0328 × resilience + 0.1175 × b* value + 0.0533 × iodine color value.</p> <p><strong>Conclusion</strong>: The AHP combined with factor analysis and cluster analysis can convert a number of quality indexes into a comprehensive quality index, and thus establish the comprehensive quality evaluation model of fresh instant rice, effectively performing the quantitative quality analysis. This model not only provided a scientific basis for the accurate evaluation of fresh instant rice quality, but also laid the foundation for the formulation of fresh instant rice standards in the future.</p> 2019-07-22T12:08:07-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/1444 Monosodium L-glutamate and fats change free fatty acid concentrations in intestinal contents and affect free fatty acid receptors express profile in growing pigs 2019-07-17T10:10:06-07:00 Yun Su 515593373@qq.com Zemeng Feng zemengfeng2006@163.com Yumin He zemengfeng2006@163.com Lingling Hong zemengfeng2006@163.com Gang Liu zemengfeng2006@163.com Tiejun Li zemengfeng2006@163.com Yulong Yin zemengfeng2006@163.com <p><strong>Background</strong>: Obesity and its related metabolic syndrome continue to be major public health problems. Monosodium L-glutamate (MSG) may cause metabolic diseases such as obesity. Meanwhile, the Chinese population has undergone rapid transition to a high-fat diet. There is little information available on the effect of MSG and fat alone, or in combination, on free fatty acids (FFAs), lipid metabolism and FFA receptors.</p> <p><strong>Objective</strong>: The aim of this study was to evaluate the effects of MSG and fat alone, or in combination, on intestinal luminal FFAs and expression of gastrointestinal FFA receptors. The aim was also to test whether dietary fat and/or MSG could affect expression of genes related to fatty acid metabolism.</p> <p><strong>Design</strong>: A total of 32 growing pigs were used and fed with four iso-nitrogenous and iso-caloric diets. Pigs in the four treatments received diets with one of two fat concentrations levels (4.4 and 9.4%) and one of two MSG dose levels (0 and 3%), in which most of the fat were brought by soybean oil. The concentration of short chain fatty acids (SCFAs) in cecum and colon, long chain fatty acids (LCFAs) in ileum, cecum and colon, and FFAs receptors expression in hypothalamus and gastrointestinal tract were determined.</p> <p><strong>Results</strong>: MSG and/or fat changed intestinal luminal SCFAs, levels of LCFAs, and showed an antagonistic effect on most of LCFAs. Simultaneously, MSG and/or fat decreased the expression of FFA receptors in hypothalamus and gastrointestinal tract. MSG and/or fat promoted fat deposition through different ways in back fat.</p> <p><strong>Conclusion</strong>: Our results support that MSG and/or fat can alter intestinal luminal FFAs composition and concentration, especially LCFAs, in addition, the expression of FFA receptors in ileum and hypothalamus could be decreased. Moreover, MSG and/or fat can promote protein deposition in back fat, and affect the distribution and metabolism of fatty acids in the body tissues and the body’s ability to perceive fatty acids; these results provide a reference for the occurrence of fat deposition and obesity caused by high-fat and monosodium glutamate diet.</p> 2019-07-17T10:08:51-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/3573 New data on nutrient composition in large selection of commercially available seafood products and its impact on micronutrient intake 2019-07-08T04:06:57-07:00 Inger Aakre inger.aakre@hi.no Synnøve Næss synnoeve.naess@hi.no Marian Kjellevold marian.kjellevold@hi.no Maria Wik Markhus maria.wik.markhus@hi.no Anita Røyneberg Alvheim anita.alvheim@hi.no Jorån Østerholt Dalane joran.osteholt.dalane@mattilsynet.no Ellen Kielland ellen.kielland@mattilsynet.no Lisbeth Dahl lisbeth.dahl@hi.no <p><strong>Background</strong>: Most foods, including seafood, undergo some sort of processing as an integrated part of the global food industry. The degree of processing depends on the type of product produced. Processed seafood products are an important part of the diet; thus, knowledge of nutrient content in seafood products is of great importance.</p> <p><strong>Objective</strong>: The aim of this study was to describe the content of selected nutrients in commercially available and market representative seafood products purchased from 3 different years. Methods: Seafood products from 2015 (n = 16), 2017 (n = 35), and 2018 (n = 35) were analyzed as composite samples for macro- and micronutrients using accredited methods at the Institute of Marine Research in Norway.</p> <p><strong>Results</strong>: This study confirms that seafood products are good sources of several key nutrients, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), vitamin D, vitamin B12, iodine, and selenium. Fatty fish products had the highest content of EPA, DHA, and vitamin D, while lean fish products had the highest content of vitamin B12 and minerals. However, some lean fish products, such as one portion of fish au gratin or fish cakes, also proved as good sources of EPA, DHA, and vitamin D, and contributed substantially to the recommended intake. Variations in nutrients were seen both within the same product category and between the same product category from different years.</p> <p><strong>Conclusions</strong>: These data give valuable insights into seafood products as a source of essential micronutrients and highlight the importance of these products for nutrition and health.</p> 2019-07-08T04:06:05-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/3449 Ethanol extracts of <em>Allium</em> sp. regulate cyclooxygenase-2 and E-cadherin expression in gastric cancer MKN74 cell line and enhance doxorubicin toxicity 2019-06-25T04:10:00-07:00 Agnieszka Korga agnieszka.korga@umlub.pl Marta Ostrowska martaostrowska@umlub.pl Magdalena Iwan magdaiwan@poczta.fm Małgorzata Skierucha malgorzata.skierucha@gmail.com Aleksandra Józefczyk ajozefczyk@pharmacognosy.org Piotr Pawłowski ppawlowski87@gmail.com Jaroslaw Dudka jaroslaw.dudka@umlub.pl Ryszard Maciejewski ryszard.maciejewski@umlub.pl Robert Sitarz robertsitarz@umlub.pl <p><strong>Background</strong>: Gastric cancer (GC) remains one of the leading causes of cancer-related death. Its aetiology is multifactorial, but the major risk factor is a high in salt diet. During gastric carcinogenesis, cadherin-1 (CDH1) down-expression and cyclooxygenase 2 (COX2) overexpression may be observed. The intensity of these alterations contributes to the GC invasion, its metastases and poor prognosis. As the diet plays a significant role in the aetiology of GC, it is reasonable to include the nutritional chemoprevention agents. One of the plant genus demonstrating chemoprotective properties is <em>Allium</em> genus, which includes garlic. The relationship between CDH1 and COX2 in GC cells treated with <em>Allium</em> species extract has never been evaluated.</p> <p><strong>Methods</strong>: In this study, the MKN28 and MKN74 GC cell lines were treated with ethanol extracts of <em>Allium angulosum</em> L., <em>Allium lusitanicum</em> Lam., <em>Allium sativum</em> L. (from Malaysia and Poland), <em>Allium tibeticum</em> Rendle and <em>Allium ursinum</em> L. The cytotoxicity of the extracts and their influence on COX2 and CDH1 mRNA and protein expression were evaluated as well as their influence on doxorubicin’s (DOX) efficacy – a drug that has been used in GC treatment.</p> <p><strong>Results</strong>: Among the tested species, ethanol extracts of <em>A. sativum</em> L. (Poland and Malaysia), <em>A. tibeticum</em> Rendle and <em>A. ursinum</em> L. influenced the levels of CDH1 and COX2, but only in the MKN74 cell line. Thus, it is possible that tumours with increased COX2 expression will be more susceptible to garlic treatment. Observed phenomenon was independent of <em>Allium</em> extract’s toxicity. In comparison to DOX, tested extracts were more toxic. Moreover, <em>A. sativum</em> revealed synergistic effect with the drug.</p> <p><strong>Conclusion</strong>: In conclusion, the results indicate the potential application of <em>Allium</em> genus to GC chemoprevention and treatment support through CDH restoration and COX2 downregulation. This issue needs further investigations as it might be used in clinics.</p> 2019-06-25T04:08:59-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/1598 A novel polysaccharide from Lentinus edodes mycelia protects MIN6 cells against high glucose-induced damage via the MAPKs and Nrf2 pathways 2019-06-06T12:11:06-07:00 Xiangyu Cao caoxiangyu@lnu.edu.cn Dan Liu 1309460740@qq.com Ying Xia 2500748971@qq.com Tiange Cai 23407038@qq.com Yin he heyinlnu@163.com Jianli Liu liujianli@lnu.edu.cn <p><strong>Background</strong>: Diabetes mellitus is one of the most widespread diseases in the world, high glucose can damage islet cells, it is important to discover new natural products to inhibit high glucose damage. The protective effects and mechanisms of a novel Lentinus edodes mycelia polysaccharide (LMP) against damage induced by high glucose in MIN6 cells were explored.</p> <p><strong>Methods</strong>: Cell viability, malondialdehyde (MDA) inhibition, lactate dehydrogenase (LDH) release and the activity of superoxide dismutase (SOD) were evaluated under 40 mM glucose with or without LMP for 48 h. Cell signaling pathway analysis was performed to investigate the possible mechanisms of the protective effects of LMP in MIN6 cells.</p> <p><strong>Results</strong>: The results showed that LMP could increase cell viability and the activity of SOD, decrease the reactive oxygen species ( ROS) production, and reduce the MDA content and LDH release in high glucose-induced MIN6 cells. Moreover, LMP prevented high glucose-induced apoptosis by decreasing the expression of Bax and the activation of caspase-1 and caspase-3. Cell signaling pathway analysis showed that p38 mitogen-activated protein kinase (MAPK) and JNK pathways were inhibited and the Nrf2 pathway was activated after treated with LMP.</p> <p><strong>Conclusion</strong>: The protective effects of LMP against MIN6 cells damage induced by high glucose might rely on the regulation of the MAPK and Nrf2 pathways. These results indicated that LMP had great potential as a therapeutic agent for the treatment of diabetes mellitus.</p> 2019-06-06T12:08:02-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/3451 Impact of cooking on the antioxidant activity of spice turmeric 2019-05-31T13:13:36-07:00 Jian-Long Sun 18369909086@163.com Hong-Fang Ji jhf@sdut.edu.cn Liang Shen shen@sdut.edu.cn <p>Curcuminoids, as the main ingredient of turmeric, are popularly used in food additives and condiments, and are widely accepted to be beneficial for human health for their antioxidant activity. However, curcuminoids are highly susceptible in terms of thermal-induced degradation, and curry is usually boiled, roasted, or fried in the use of food additives and condiments. Thus, it is interesting to explore the effect of cooking on the antioxidant activity of curcuminoids. In the present study, the total antioxidant capacity (T-AOC) of cooked curcuminoids (boiled curcuminoids, roasted curcuminoids, and fried curcuminoids) processed through three heating conditions, and their protective effects against oxidative damage to rat pheochromocytoma (PC12) cells, a well-established neuronal model, were evaluated. It was found that cooking slightly lowered the T-AOC of curcuminoids, with boiled curcuminoids being relatively stronger than roasted curcuminoids, and fried curcuminoids being the weakest form. Both boiled and roasted curcuminoids could significantly improve cell viability, mitigate intracellular accumulation of reactive oxygen species and reduce malondialdehyde activity, reduce caspase-3 and caspase-9 protein expression, and increase superoxide dismutase activity of PC12 cells compared with the control group. In comparison with parent curcuminoids, the protective effects of cooked curcuminoids got relatively lower overall, with boiled curcuminoids being relatively stronger than roasted curcuminoids. In conclusion, the cooked curcuminoids, including boiled and roasted forms, still have antioxidant and neuroprotective activity.</p> 2019-05-31T13:13:11-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/1560 Effects of ad libitum consumed, low-fat, high-fiber plant-based diet supplemented with plant-based meal replacements on cardiovascular risk factors 2019-05-21T13:19:12-07:00 Boštjan Jakše bostjanjakse@hotmail.com Barbara Jakše barbara.tursic@gmail.com Jernej Pajek jernej.pajek@mf.uni-lj.si Maja Pajek maja.bucarpajek@fsp.uni-lj.si <p><strong>Background</strong>: Sustainable nutritional strategies to reduce risk factors of cardiovascular diseases are highly needed. Inclusion of meal replacements may increase adherence to plant-based diets (PBDs).</p> <p><strong>Objective</strong>: The aim of this study was to test the effects of a transition from a western-type diet to a new nutritional paradigm with a PBD from predominately unrefined whole food sources, eaten ad libitum and including nutrient-enriched plant-based meal replacements twice daily.</p> <p><strong>Design</strong>: This was a single-arm, prospective interventional trial for 10 weeks in 36 participants with extension to 36 weeks in 18 participants. The main endpoint was serum low-density lipoprotein (LDL)-cholesterol measured at baseline, after 10 weeks (phase 1), and after 36 weeks (phase 2). Secondary endpoints included total, non-high-density lipoprotein (HDL) and HDL-cholesterol, fasting glucose, uric acid, and insulin-like growth factor-1 (IGF-1).</p> <p><strong>Results</strong>: The mean reduction in LDL-cholesterol was 0.6 (95% confidence interval [CI], 0.3–0.8) mmol/L (−15%, P &lt; 0.001) at the end of phase 1, with no further change by the end of phase 2. Similar reductions were noted for non-HDL-cholesterol and total cholesterol. HDL-cholesterol was reduced by 0.16 mmol/L (95% CI, 0.1–0.2). There was a borderline reduction in fasting glucose (5.2 to 5 mmol/L in phase 1, P = 0.08) and a small significant rise in serum uric acid levels of 15 (95% CI, 1–28) μmol/L, P &lt; 0.05. Median baseline value for IGF-1 concentration was 156 μg/L. Participants with baseline IGF-1 below median had a significant increase in IGF-1 value from baseline 110 ± 31 to 132 ± 39 at the end of phase 1 (mean change of +22 μg/L, 95% CI, 11–33, P = 0.001). Participants with baseline IGF-1 above median had no significant change in IGF-1. Significant reductions in body weight, body fat, and visceral fat were observed.</p> <p><strong>Conclusions</strong>: Supplemented, unrefined PBD eaten ad libitum was effective in improving total and LDL-cholesterol, non-HDL-cholesterol, and IGF-1 in low baseline IGF-1 subgroup.

Anemia is intricately linked to chronic inflammation, chronic kidney disease, gastrointestinal and gynecological malignancies, and autoimmune disorders. Hemorrhagic anemia results in substantial loss of blood, which causes significant alterations in all blood parameters, including reduced iron. The other type of anemia is chronic anemia syndrome (CAS), which is a constellation of disorders and chronic inflammatory events caused by an increasing anaerobic/acidic environment (promoting the growth of anaerobic organisms), inducing a defensive expenditure of alkalinizing buffers in hemoglobin (i.e. histidine), to prevent a dangerous lowering of blood pH. In this process, iron is cleaved from heme groups and transferred out of blood circulation into other organs, like the liver, appearing to be IDA, where excessive accumulation can lead to hemochromatosis, also known as ‘iron overload anemia’.</p> <p><strong>Design</strong>: A pilot clinical study was conducted in 38 subjects (men = 10; women = 28; age = 22–82 years) to evaluate the rate of absorption and effects on blood of VMP35 multi-nutrient complex (MNC), a non-iron containing liquid nutraceutical supplement. Subjects consumed either placebo or VMP35 (30 mL) over a period of 0, 5, or 30 min.</p> <p><strong>Methods</strong>: Changes in peripheral blood smears from 38 subjects were observed using live blood cell imaging (LBCI) with phase contrast microscopy. Adverse events were rigorously monitored.</p> <p><strong>Results</strong>: VMP35 caused positive changes in the blood, including morphological, hematological (including restoration of hemoglobin), and rheological changes following 5 min of administration, which were sustained for at least 30 min.</p> <p><strong>Conclusion</strong>: Overall, the non-iron containing VMP35 can induce improvements in blood properties and potential benefits for subjects even with compromised digestive systems. No adverse events were reported.

To promote the full utilization of kiwifruit resources it is essential to explore the nutritional benefits of kiwifruit peel.</p> <p><strong>Objective</strong>: Our studies explored the difference in polyphenolic composition and biological activity including antioxidant, antimicrobial, and antiproliferative activity of the flesh and peel of kiwifruit.</p> <p><strong>Design</strong>: Antioxidant activity of the extracted polyphenols of the peel and flesh of A. chinensis was checked by 2,2-diphenyl-1-picrylhydrazyl, 2,2’-azino-bis3-ethylbenzothiazoline-6-sulphonic acid (ABTS), hydroxyl ion reduction, and ion chelating ability. Antibacterial activity against Escherichia coli, Listeria monocytogenes, and Staphylococcus aureus and antiproliferative activity against HepG2 was tested in a dose- and time-dependent manner. Liquid chromatography/mass spectrometry (LC/MS) chromatogram of the peel and flesh further differentiated the phenolic acid profile.</p> <p><strong>Results</strong>: The pericarp of kiwifruit was found to be more abundant in polyphenols and flavonoids than the flesh, with contents of 12.8 mg/g and 2.7 mg/g, respectively. LC/MS analysis revealed that the catachin, quercetin and epigallocatechin content (the main polyphenols in kiwifruit) in the peel was significantly higher than in the flesh (P &lt; 0.05). The antioxidant and antibacterial activity of the peel was significantly higher when compared to the flesh. Moreover, the proliferation of HepG2 cells was time- and dose-dependently inhibited by kiwifruit polyphenols, with IC50 values of 170 μg/mL and 291 μg/mL for peel and flesh polyphenols after 72 h of treatment time, respectively.</p> <p><strong>Conclusion</strong>: Kiwifruit peel, with higher content of phenolics and flavonoids, exerts more potent antioxidant, antibacterial, and anticancer activity than the flesh.

However, the hepatoprotective effects of Bianliang ziyu and their underlying mechanisms are not clear.</p> <p><strong>Objective</strong>: In this study, we investigated the hepatoprotective and antioxidative effects of Bianliang ziyu extract (BZE) on liver injury and explored its molecular mechanisms.</p> <p><strong>Design</strong>: Sprague-Dawley rats were administered BZE by intragastric administration for 8–9 days, and then alcohol or carbon tetrachloride (CCl4) was administered by gavage to induce acute liver injury. The activities of serum alanine aminotransferase, aspartate aminotransferase, superoxide dismutase, and malondialdehyde in the rats were measured, and the liver of each rat was examined for histopathological changes. In vitro, HL-7702 cells were pretreated with BZE for 24 h and then exposed to 30 mmol•L−1 acetaminophen (APAP) for 12 h. The survival rate of the cells and the alanine aminotransferase and aspartate aminotransferase activities were determined. Then, we investigated the effects of BZE on oxidative stress, apoptosis, and the activation of nuclear factor erythroid-2-related factor 2 (Nrf2) signaling in HL-7702 cells induced by APAP.</p> <p><strong>Results</strong>: The results showed that BZE prevented alcohol-, CCl4-, and APAP-induced liver injury and suppressed hepatic oxidative stress in vitro and in vivo. BZE was also observed to significantly inhibit the reduction of mitochondrial membrane potential and regulate the expression of Bcl-2, Bax and Caspase-3 in APAP-induced HL-7702 cells. In addition, BZE significantly promoted nuclear translocation and the expression of Nrf2 as well as its downstream gene hemeoxygenase-1 (HO-1) in vitro.

In addition to being consumed fresh, numerous kiwifruit products are popular, such as kiwifruit juice, vinegar, dried slices, jam, wine, yogurt, and jelly. Although many studies have described the nutritional properties of kiwifruit, investigations on the nutritional properties of kiwifruit products remain limited, especially for kiwifruit products made from raw kiwifruit.</p> <p><strong>Methods</strong>: Nutritional properties and biological activities of kiwifruit and kiwifruit products, as well as the digestive and absorption characteristics of their nutritional substances, were investigated.</p> <p><strong>Results</strong>: Kiwifruit, juice, wine, and vinegar were observed to be rich in vitamin C (VC) and polyphenol and exhibited high biological activities, whereas dried kiwifruit slices and jam showed higher amounts of mineral elements. During oral digestion, VC and polyphenol showed similar absorption characteristics, while mineral elements exhibited a number of different trends. A good release rate of all nutritional substances was observed during stomach digestion, while the release rate decreased in serum-available, colon-available, and post-colonic fractions. Eating dried slices and jam supplied high amounts of mineral elements, while eating kiwifruit supplied the most comprehensive nutritional substances. The biological activities detected in raw foodstuffs were much higher than those detected after in vitro digestion.

Height and weight were collected and BMI was calculated, after which the children were grouped as underweight, normal, overweight, and obese. For caries registration, the International Caries Detection and Assessment System and Decayed Missing Filled Surfaces indices were used.</p> <p><strong>Results</strong>: A statistically significant difference was found for BMI among the children from the three countries (p &lt; 0.001), with the highest mean found among Saudi children, followed by Mexican and Italian children. A statistically significant difference regarding sweet taste threshold when comparing the BMI groups was only found for Saudi Arabia (p &lt; 0.01). No significant correlation was found between BMI and sweet taste threshold or preference and dental caries variables, respectively.</p> <p><strong>Conclusions</strong>: BMI was found to differ between countries, with a further significant difference among the groups among the Saudi Arabia schoolchildren.</p> 2019-04-04T11:15:16-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/1441 Effect of chronic administration of arachidonic acid on the performance of learning and memory in aged rats 2019-03-25T06:02:52-07:00 Takayuki Inoue takayuki.nus@gmail.com Michio Hashimoto michio1@med.shimane-u.ac.jp Masanori Katakura mkatakur@josai.ac.jp Shahdat Hossain shahdat@juniv.edu Kentaro Matsuzaki matuzaki@med.shimane-u.ac.jp Osamu Shido o-shido@med.shimane-u.ac.jp <p><strong>Background</strong>: Arachidonic acid (AA, C20:4, ω-6) is a ω-6 polyunsaturated fatty acid (PUFA) and plays diverse roles in cell signaling. Numerous reports on the effects of ω-3 PUFAs, such as docosahexaenoic acid (DHA, C22:6, ω-3) and eicosapentaenoic acid (EPA, C20:5, ω-3) on learning and memory impairments of rats are available, however, the role of AA on brain cognition is largely unknown.</p> <p><strong>Objective</strong>: In this study, our aim was to investigate the effect of oral administration of AA on spatial memory- related learning ability in aged (100 weeks) male rats.</p> <p><strong>Design</strong>: One group was per orally administered 240 mg/kg per day AA oil and the other group was administered the similar volume of control oil. Five weeks after the start of the administration, rats were tested with the partially baited eight-arm radial maze to evaluate two types of spatial memory-related learning ability displayed by reference memory errors (RMEs) and working memory errors (WMEs). Also, the time required to complete the task was recorded. The levels of lipid peroxide (LPO) and reactive oxygen species (ROS) were measured, as an indicator oxidative stress in the plasma and brain corticohippocampal brain tissues.</p> <p><strong>Results</strong>: The scores of RMEs and WMEs, which are analogous to long-term and short-term memory, respectively, were not affected, however, the trial time was shorter in the AA-administered rats than that of the controls. AA also significantly increased the degree of oxidative stress both in the plasma and corticohippocampal brain tissues.</p> <p><strong>Conclusions</strong>: Our results suggest that though AA deposition in the corticohippocampal tissues of senescent rats caused a faster performance activity, which is reminiscent to hyperactive behavior of animals, the spatial learning ability-related memory of the rats, however, was not improved.</p> 2019-03-25T06:02:10-07:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/3437 Cod protein powder lowered serum nonesterified fatty acids and increased total bile acid concentrations in healthy, lean, physically active adults: a randomized double-blind study 2019-03-11T04:09:59-07:00 Iselin Vildmyren iselin.vildmyren@uib.no Alfred Halstensen alfred.halstensen@uib.no Åge Oterhals Aage.Oterhals@Nofima.no Oddrun A.

A 10-food group indicator is proposed by the Food and Agriculture Organization of the United Nations as a global standard for measuring dietary diversity among women in low-resource settings. However, its validity as a proxy for nutrient adequacy across different agricultural seasons for pregnant women has not been determined.</p> <p><strong>Objective</strong>: We studied associations between DDS and nutrient adequacy ratios (NAR) across two different agricultural seasons (pre- and post-harvest seasons) for pregnant women in rural Malawi and assessed whether a 1-day DDS or a 3-day DDS would be the best indicator of nutrient adequacy.</p> <p><strong>Design</strong>: Dietary intakes of 330 pregnant women were assessed between gestational weeks 28 and 35. Intakes of energy, macronutrients, and 11 micronutrients were estimated using three repeated interactive 24-h diet recalls, and DDS were also calculated from these days. Correlation coefficients (r) between DDS, NAR, and mean adequacy ratio (MAR) of the 11 micronutrients were determined.</p> <p><strong>Results</strong>: After energy adjustments, we found significant correlations between DDS and MAR with both DDS indicators in the preharvest season (r = 0.22–0.23; p &lt; 0.001) but not in the post-harvest season (p &gt; 0.05). For individual energy-adjusted NARs, correlations were not consistently significant across the two seasons and the two DDS indicators.</p> <p><strong>Conclusions</strong>: Our results suggest that DDS could be used to predict overall nutrient adequacy during the preharvest season. As similar correlations were found using both the 1- and 3-day indicators, we recommend using a 1-day DDS, for simplicity. However, as the indicators are sensitive to seasonality they should be used with care in this study setting.</p> 2019-02-27T01:36:07-08:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/1591 Cereal fiber improves blood cholesterol profiles and modulates intestinal cholesterol metabolism in C57BL/6 mice fed a high-fat, high-cholesterol diet 2019-02-25T08:27:50-08:00 Shufen Han sfhan@suda.edu.cn Wei Zhang zhagnwei0906@sina.com Ru Zhang 827473266@qq.com Jun Jiao 367102935@qq.com Chunling Fu fuchunling0101@sina.com Xing Tong tongxing0212@sina.com Weiguo Zhang weiguozha@yahoo.com Liqiang Qin qinliqiang@suda.edu.cn <p><strong>Background</strong>: Dietary intake of cereal fiber has been reported to benefit lipid metabolism through multiple mechanisms. The present study aimed to discover the potential mechanisms by which cereal fiber could modify the intestinal cholesterol metabolism.</p> <p><strong>Design</strong>: Male C57BL/6 mice were fed a reference chow (RC) diet; high-fat, high-cholesterol (HFC) diet; HFC plus oat fiber diet; or HFC plus wheat bran fiber diet for 24 weeks. Serum lipids were measured by enzymatic methods. Western blot was used to determine the protein expressions involved in intestinal cholesterol metabolism.</p> <p><strong>Results</strong>: Our results showed that HFC-induced elevations of serum triglycerides, total cholesterol, and low-density lipoprotein cholesterol were normalized in both groups that received cereal fiber. At the protein level, compared with the HFC diet group, the two cereal fibers, especially the oat fiber, significantly increased the protein expression of peroxisome proliferator-activated receptor alpha, liver X receptor alpha, sterol regulatory element- binding protein (SREBP) 2, low-density lipoprotein receptor, adenosine triphosphate (ATP)-binding cassette A1, and ATP-binding cassette G1, while decreasing the protein expression of Niemann-Pick C1-like protein 1, SREBP-1, fatty acid synthase, and acetyl-coenzyme A carboxylase, which were involved in intestinal cholesterol metabolism.</p> <p><strong>Conclusion</strong>: Taken together, increased intake of cereal fiber improved blood cholesterol profiles and increased the intestinal cholesterol efflux and cholesterol clearance in C57BL/6 mice fed a HFC diet. Oat fiber had a stronger effect than wheat bran fiber on cholesterol metabolism by modulating the PPARα, LXRα, and SREBP signaling pathways.</p> 2019-02-25T08:27:08-08:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/1604 The extent, nature, and nutritional quality of foods advertised to children in Lebanon: the first study to use the WHO nutrient profile model for the Eastern Mediterranean Region 2019-02-19T04:48:00-08:00 Lara Nasreddine ln10@aub.edu.lb Mandy Taktouk mt86@aub.edu.lb Massar Dabbous massardabbous@gmail.com Jad Melki jmelki2000@gmail.com <p><strong>Objective</strong>: Exposure to food marketing may influence children’s food preferences and consumption patterns and may increase the risk of childhood obesity. The WHO Office for the Eastern Mediterranean Region (EMR) has recently released a regional nutrient profile model (WHO EMR) for the purpose of regulating the marketing of food and beverages to children. This study aimed at 1) analyzing the frequency and types of food and drink advertisements during children’s viewing time in Lebanon; 2) examining the nutritional content of the advertised food products in reference to the nutrient thresholds specified by the WHO EMR model; and 3) assessing the proportion of food advertisements that included health messages.</p> <p><strong>Design</strong>: This study consisted of a cross-sectional content analysis of food advertisements on local TV channels, during children’s viewing time. Setting: Three local Lebanese channels with the highest viewership among 4- to 14-year-olds were selected. Recorded broadcasts (September 2016 through January 2017) were analyzed between 3 pm and 10 pm on weekdays and between 8 am and 10 pm on weekend days.</p> <p><strong>Results</strong>: Approximately 31% of advertisements were for foods or drinks. The proportion of food advertisements was the highest during children’s programs (43%) compared to general viewing (32%) and parental guidance (29%) programs. Approximately 8 out of 10 food advertisements were for products that did not meet the standards of the WHO EMR model. Of concern was the heavy advertisement of alcoholic beverages during programs for general audiences. The majority of the advertisements that comprised a health claim were for foods that did not meet the WHO EMR’s nutritional standards (79%).</p> <p><strong>Conclusions</strong>: The findings of this study, which is the first to utilize the new WHO EMR profile model, should be viewed as a foundation for the development of food marketing policies aimed at reducing children’s exposure to TV food advertisements in Lebanon, a country that harbors a high burden of childhood obesity.</p> 2019-02-19T04:29:47-08:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/1559 <em>Ganoderma lucidum</em> polysaccharide improves rat DSS-induced colitis by altering cecal microbiota and gene expression of colonic epithelial cells 2019-02-18T21:53:06-08:00 Jinli Xie 1169975820@qq.com Yanghanxiu Liu 1026625578@qq.com Bohui Chen cdliuliu@126.com Guangwen Zhang tzgw@jnu.edu.cn Shiyi Ou tosy@jnu.edu.cn Jianming Luo baiding86@126.com Xichun Peng tpxchun@jnu.edu.cn <p><strong>Background</strong>: The effects of β-glucan on colitis mice are contradictory in previous reports. As a result, it is still unclear whether there is an anti-colitis effect in Ganoderma lucidum polysaccharide (GLP), which is mainly composed of β-glucan. Moreover, the association between GLP function and gut microbiota remains to be elucidated.</p> <p><strong>Objective</strong>: This study aimed to investigate whether GLP consumption improved rat dextran sodium sulfate (DSS)-induced colitis by regulating gut microbiota and altering colonic epithelial expression.</p> <p><strong>Design</strong>: The disease activity index (DAI) scores and the cecal short chain fatty acid (SCFA) levels of DSS-induced colitis rats fed with a GLP diet (Group GLP, n = 6) and a control diet (Group Con, n = 6) were investigated and analyzed. Moreover, the profiles of gut microbiota and colonic epithelial expression were analyzed using metagenomics and transcriptomics.</p> <p><strong>Results</strong>: GLP consumption significantly lowered animal DAI scores by producing more SCFAs by increasing SCFA-producing bacteria such as Ruminococcus_1 and reducing pathogens such as Escherichia-Shigella in both the small intestine and cecum of rat. Moreover, GLP consumption regulated 11 genes, including six upregulated (Ccl5, Cd3e, Cd8a, Il21r, Lck, and Trbv) and five downregulated (Ccl3, Gro, Il11, Mhc2, and Ptgs) genes enriched in six inflammation-related Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, resulting in enhancement of immunity and reduction of inflammatory response and colonic cancer risk.</p> <p><strong>Conclusions</strong>: GLP consumption alleviated DSS-induced colitis and may have potential for ulcerative colitis relief.</p> 2019-02-12T11:52:47-08:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/1553 Determinants of dietary diversity among women of reproductive age in two different agro-ecological zones of Rongai Sub-County, Nakuru, Kenya 2019-01-18T01:10:22-08:00 Maureen Wanjiru Gitagia maureengeorge84@gmail.com Rose Chepchirchir Ramkat chirirose@yahoo.com Dorothy M Mituki dotmituki@yahoo.com Celine Termote c.termote@cgiar.org Namukolo Covic n.covic@cgiar.org Maureen Jepkorir Cheserek mjcheserek@yahoo.co.uk <p><strong>Background: </strong>&nbsp;Empirical evidence on the link between agro-biodiversity and dietary diversity appears to be inconclusive. Thus, arises a need to determine other factors that could significantly influence dietary diversity in different agro-ecological zones as factors may vary from region to region.</p> <p><strong>Objective</strong>: This study assessed the determinants of dietary diversity (DD) among women of reproductive age in two different agro-ecological zones of Rongai Sub-County in Kenya; with agrobiodiversity being the main independent predictor.</p> <p><strong>Design:</strong> A cross-sectional study targeting 400 women aged 18-49 years was conducted. Agro-biodiversity was measured using Shannon-Wiener index, species richness/count and production diversity score. A 24-hour dietary recall was used to determine minimum dietary diversity for women (MDD-W) of reproductive age.</p> <p><strong>Results:</strong> Although the level of agrobiodiversity was different between the low and high agro-ecological zones (using Shannon-Wiener index); the women dietary diversity was not different (P&gt;0.05) between low (3.78 ± 0.99) and high potential areas (3.84 ± 1.05). In multivariate logistic regression, there was no association (P&gt;0.05) between agro-biodiversity indicators and dietary diversity across the two agricultural zones. Other factors influenced dietary diversity and varied across the two agro-ecological zones. In low potential areas, women education level positively influenced dietary diversity while in high potential areas household gender, women education level, woman’s age and household size influenced MDD-W.</p> <p><strong>Conclusion: </strong>This paper informs that factors other than agrobiodiversity influenced dietary diversity among women of reproductive age and these determinants varied across the agro-ecological zones. Therefore, it is recommended that nutrition interventions focusing on lessening malnutrition and improving dietary quality should pay special attention to differences in agro-ecological zones to develop region specific interventions instead of generalized interventions.</p> 2019-01-18T00:11:27-08:00 ##submission.copyrightStatement## https://foodandnutritionresearch.net/index.php/fnr/article/view/1616 <em>In vitro</em> and <em>in vivo</em> antitumour effects of coconut water vinegar on 4T1 breast cancer cells 2019-01-10T12:31:34-08:00 Nurul Elyani Mohamad elyani.mohamad@gmail.com Swee Keong Yeap skyeap2005@gmail.com Nadiah Abu nadyaboo@gmail.com Kian Lam Lim promelkl@gmail.com Nur Rizi Zamberi rizieaq@gmail.com Noraini Nordin noraini90.nordin@gmail.com Shaiful Adzni Sharifuddin shaiful@mardi.gov.my Kamariah Long amai@mardi.gov.my Noorjahan Banu Alitheen noorjahan@upm.edu.my <p><strong>Background</strong>: Coconut water and vinegars have been reported to possess potential anti-tumour and immunostimulatory effects.
