Using the SCM technique, this study evaluates culturally competent health and nutrition education trainings on diabetes type II control directed to (50) male Latinos/Hispanics living in Atlanta, Georgia. United States. In order to identify the most (and least) successful participants, a brief 5-questions survey was provided four (4) weeks after the completion of the training. Five (5) factors were selected as measures of success: (1) Initiation, (2) Continuity, (3) Self-Assessment, (4) Knowledge Sharing, and (5) Applicability to which participants had to determine on a scale of 1 to 5 their level of success. A random sample of five (5) of most successful and five (5) least successful participants were selected for interviews with the purpose of getting a deeper sense of the participants experience and determine the exact nature and extent of their success. Results revealed that most participants achieved success as a result of the training, with a higher number of “most successful” cases in initiation, continuity, self-assessment, and knowledge sharing. Applicability was not successfully achieved by a large number of participants, for example, how physical activity is important not only for diabetes type II control but also for high blood pressure control. In-depth interviews revealed that language, culture, credentials, clarification and family support are benefits for success, while, lack of time, income, supplies, lack of family support, and education are barriers for success. The results demonstrate the need for topic specific trainings that provide knowledge and skills for this community on chronic disease prevention and health promotion; the importance of social assistance in order to address barriers and the influence of family support in the Latino men health status and decision-making.","PeriodicalId":16764,"journal":{"name":"Journal of Nutrition and Food Sciences","volume":"93 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84178086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The two main fractions of meat proteins, myofibrillar and sarcoplasmic are affected differently by the treatments and the condition of the meat. The aim of this study was to extract myofibrillar and sarcoplasmic proteins from the chicken breast meat and determine differences in protein extractability between normal and PSE meat, and determine temperature transitions in whole muscle and its constituent proteins. The protein concentration of sarcoplasmic protein was less than that of myofibrillar protein in chicken breast muscle. It was also found that the protein solubility differed in normal and PSE muscle. The PSE muscle showed lower protein solubility as compared to the normal muscle which was assumed to be due to the denaturation of some of the protein fractions in PSE muscle. The results of SDS-PAGE did not show much variance in the protein profiles of the PSE and normal samples indicating that the solubilized protein in PSE and normal samples was similar. Thermal denaturation determined using differential Scanning Calorimeter, identified thermal transition peaks which could be of value in the design a scheduled heating sequence for cooking of chicken breast.","PeriodicalId":16764,"journal":{"name":"Journal of Nutrition and Food Sciences","volume":"35 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88005826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nephrotoxicity was induced by a single intraperitoneal injection of cisplatin (20 mg/kg) and treated with white ginseng (WB) and FBG (200 mg/kg/day, orally) for 4 days before cisplatin treatment. Biochemical results showed that WG and FBG pretreatment significantly reduced the increase of blood urea nitrogen (BUN) and creatinine, and histopathological changes were meaningfully ameliorated. Cisplatin increased the production of reactive oxygen species (ROS) and depletion of Glutathione (GSH) in serum and kidney, whereas, WG or FBG administration markedly down-regulated. Moreover, the expression of nuclear factor-kappaB (NF-κB), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), tumor necrosis factor-α (TNF-α), and interleukin (IL)-6 was markedly suppressed by both WB and FBG. However, FBG pretreatment was more effective than those of WG in COX-2, iNOS, and IL-6 levels. Moreover, FBG treated mice significantly up-regulated the antioxidative enzymes. In HPLC analysis, the increasing ginsenoside contents that include Rg1, Re, Rb1, Rc, Rb3, Rd, Rg3, Rk1, and Rg5 by heat-processing were greater about 5.7 fold when fermentation additionally. Taken together, FBG may be a worthful candidate for the prevention of nephrotoxicity in patients receiving cisplatin.","PeriodicalId":16764,"journal":{"name":"Journal of Nutrition and Food Sciences","volume":"33 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88248876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strategies for losing weight have so far proved unsuccessful, and compounding the problem is that funding for clinical nutritional research studies is limited. Food companies can fund clinical studies, supervised by nutritional researchers. Herein is such a study where a food company’s customers were provided five, free, portion-controlled, nutrient-dense meals each day for 15 days to help improve their diet quality and lose weight. In exchange, participants completed data collection forms and posted video and comments on social media. Both normal weight (n=46) and overweight and obese subjects (n=97) participated. Subjects consumed four to five of the nutrient-dense meals, which contributed about 1,250 kcal daily and about 140%-165% of the Daily Value for all vitamins and minerals, except sodium. In addition, they consumed other foods adding another 250-300 kcal. The group lost a significant amount of weight (1.5 ± 4.5 kg; P<0.0001). After 15 days, more than 60% of the participants reported feeling better, having better sleep, and having more energy. In the subgroup of overweight and obese subjects, weight loss was 2 ± 2 kg in the overweight group (P<0.001) and for obese subjects, it was 2 ± 7 kg (P<0.01). Of this group, 17 lost at least 5% body weight, which is medically significant. Waist circumference decreased significantly for overweight women (P<0.001), overweight men (P=0.005), and obese men (P<0.0001). Waist circumference normalized in 12 individuals, indicating a reduction in the risk of hypertension, type 2 diabetes, and cardiovascular disease. The findings suggest that nutrient-dense meals, promote weight loss and improve health. Spontaneous energy-restriction occurred without hunger by consuming nutrient-dense foods. Weight loss strategies of the future may focus on nutrient-counting rather than calorie-counting.","PeriodicalId":16764,"journal":{"name":"Journal of Nutrition and Food Sciences","volume":"23 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88251754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is used as a supplement, most typically as calcium carbonate, to assist in preserving bone density especially when dietary calcium intake is inadequate. In the present study we examined the effect of five varied calcium sources, three natural and two synthetic, on stimulation, proliferation and mineralization of cultured human osteoblast cells. A MTT assay using cultured human fetal osteoblast cells (hFOB 1.19) was used to determine the effective proliferative dose for salmon collagen bone calcium (0.25 mg/ml). Elemental calcium equivalence was used to select the appropriate doses for algae calcium (0.14 mg/ml), eggshell powder (0.16 mg/ml), calcium citrate (0.22 mg/ml) and calcium carbonate (0.13). Alkaline phosphatase activity, DNA synthesis rates and calcium ion deposition were evaluated after incubation under different conditions and harvesting the cells. Alkaline phosphatase activity, DNA synthesis rates and calcium ion deposition rates were all highest for the natural salmon bone collagen calcium, followed by algae calcium. The eggshell powder, calcium citrate and calcium carbonate did not exhibit significant changes from control in most of these assays. The results of these assays suggest that natural marine collagen calcium such as salmon bone collagen calcium acts as the most effective intervention on osteoblast performance and actual calcium deposition. It should be recommended as a superior supplement for improved bone and joint health function.","PeriodicalId":16764,"journal":{"name":"Journal of Nutrition and Food Sciences","volume":"40 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86373223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We studied the effect of PF on the secretion of glucagon-like peptide-1 (GLP-1) and the involvement of SCFAs in this process, using the knockout (KO) mice for the SCFA receptors G protein-coupled receptor 41 (GPR41) and G protein-coupled receptor 43 (GPR43). Wild type (WT) or KO mice were fed either a standard formula (SF) or PF for two weeks, and then were orally administered either PF or SF after overnight fasting and dissected after 0, 30, 60, and 240 minutes. Blood GLP-1 and glucose levels were measured (Experiment 1). Alternatively, mice fed SF or PF for two weeks were dissected after four hours of fasting, and their blood GLP-1 and cecal SCFAs levels were measured (Experiment 2). In Experiment 1, WT and GPR43KO mice showed a significant increase in GLP-1 concentration 30 and/or 60 minutes after formula administration in the PF group compared with that in the SF group. Similarly, WT and GPR43KO mice showed a significant suppression of the increase in glucose levels after formula administration in the PF group compared with that in the SF group. On the other hand, there was no significant difference in GLP-1 concentration or blood glucose levels between the two treatment groups in GPR41KO mice. In Experiment 2, there was a significant increase in cecal SCFA levels in the PF group compared with that in the SF group for all mice, as well as an increase in GLP-1 concentration. PF promotes GLP-1 secretion and SCFAs might contribute to the GLP-1 secretion that occurs directly after ingestion, through GPR41 signal transduction.","PeriodicalId":16764,"journal":{"name":"Journal of Nutrition and Food Sciences","volume":"100 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83348773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study hypothesizes that differential adherence as examined by per-protocol analysis will affect the magnitude of differences in maternal and neonatal vitamin D status between treatment groups.Study design: A double-blind, RCT of vitamin D supplementation (400, 2000 or 4000IU/day) in 350 Caucasian, African American and Hispanic women with singleton pregnancies was conducted. This study defines adherence as 75% and 85% of pills taken between visits and examines the effect of adherence on vitamin D status across treatment groups. The primary outcome, measured by radioimmunoassay, is maternal serum 25(OH)D throughout pregnancy, one month prior to delivery (PTD) and neonatal serum 25(OH)D at delivery.Results: No statistically significant difference in maternal 25(OH)D throughout pregnancy, 1-month PTD, or neonatal 25(OH)D were found between 75% adherent participants and nonadherent participants regardless of supplementation. At 85% adherence, maternal 25(OH)D throughout pregnancy, one month PTD, and neonatal 25(OH)D were significantly higher in the 4000IU group compared to nonadherent participants (p=0.0002, p=0.0074, p=0.0068, respectively). No significant differences were found with 400 or 2000IU supplementation regardless of adherence.Conclusions: Participants 85% adherent to protocol and receiving 4000IU vitamin D were the only group that demonstrated significantly higher vitamin D status for each outcome: maternal 25(OH)D throughout pregnancy, 1-month PTD and neonatal 25(OH)D. Compared to intent-to-treat, this powerful per-protocol analysis demonstrates the impact that nonadherence can have on study results and has implications for how clinical trial data are analyzed and presented.","PeriodicalId":16764,"journal":{"name":"Journal of Nutrition and Food Sciences","volume":"6 18 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78507943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
