Freeze–thawed characteristics of lactone tofu under the synergy of low‐frequency electrostatic field

AbstractThe formation and melting of ice crystals bring undesirable changes to the gel structure of frozen food. To explore the role of Low‐frequency electrostatic field (LFE‐field) in the freeze–thaw quality of protein‐rich foods, the freezing temperature, thawing temperature, and the participation of the LFE‐field were used as variables to orthogonally optimize the treatment of tofu. The sensory score, color, moisture, aerobic bacterial count, and micromorphology were recorded to evaluate the quality variation of tofu. When be frozen at −50°C and thawed at 10°C, tofu maintains 91.1% hardness and 87.0% elasticity hinging on the effect of LFE‐field. When be frozen at −60°C in LFE‐field and thawed at 10°C, tofu maintains 90.7% hardness and 89.7% elasticity. The LFE‐field treatment also increased the water retention capacity and reduced the damage of ice crystals to the protein matrix structure of tofu. In addition, the LFE‐field has minimal impact influence on the tofu's color.Practical applicationsThe low‐frequency electrostatic field (LFE‐field) treatment increased the water retention capacity and reduced the damage of ice crystals to the protein matrix structure of tofu during the freeze–thaw process. In the future, the small LFE‐field could easily be installed in refrigerator and used for long time freezing preservation protein rich food to extend its shelf life and improve the storage quality, such as cheese, tofu, etc.

Factors associated with anaemia among pregnant women in Rwanda: an analysis of the Rwanda demographic and health survey of 2020

BackgroundAnaemia in pregnancy is associated with several adverse outcomes for mothers and newborns, as well as their families. In this study, we assessed the prevalence of anaemia and the associated factors among pregnant women in Rwanda.MethodsSecondary data from the 2020 Rwanda Demographic and Health Survey (RDHS) was used. Multistage stratified sampling was used to select 435 pregnant women included in the study. Anaemia among pregnant women was defined as a haemoglobin value < 11 g/dL. Multivariable logistic regression was used to assess the associated factors with anaemia in pregnancy, using SPSS (version 26).ResultsOf the 435 pregnant women, 24.6% (95%CI: 21.1–29.3) were anaemic (1 in 4 pregnant women). Not working (AOR = 2.45; 95%CI: 1.14–5.26), being unmarried (AOR = 1.23; 95%CI: 1.24–3.57), low wealth index (AOR = 9.19; 95%CI: 1.64–51.56), having difficulty accessing a nearby health facility (AOR = 5.40; 95%CI: 2.21–13.23), and normal body mass index (AOR = 3.33; 95%CI: 1.46–7.59) were associated with higher odds of being anaemic. However, not taking iron supplements (AOR = 0.16; 95% CI: 0.04–0.67), having no exposure to television (AOR = 0.35; 95%CI: 0.14–0.91), being from the southern region (AOR = 0.14; 95% CI: 0.03–0.66), and low husband/partner’s education (AOR = 0.08; 95% CI: 0.01–0.59) were associated with lower odds of being anaemic.ConclusionsThe study findings indicate a high prevalence of anaemia in pregnancy, which was associated with several socio-demographics. There is a need for setting up mobile clinics and health facilities in hard-to-reach areas for easy accessibility to early anaemia screening services. Conducting mass screening for anaemia targeting pregnant women who are not working, the unmarried, and those with a low wealth index would also be beneficial. The intake of locally available iron rich foods and/ or bio-fortified foods is also recommended.

First record of well-preserved canid coprolites from Eurasia: New insights into the unique ecological niche of Yuanmou Basin

This study reconstructs the Early Pleistocene paleoenvironment of the Yuanmou Basin through coproecology of the third member of the Yuanmou Formation. We examined 38 exceptionally well-preserved coprolites from a new fossil locality, and attributed the putative defecating agent to the hypercarnivorous diet canid, Sinocuon yuanmouensis through geochemical and quantitative analyses. A new ichnogenus and ichnospecies, Cuocopros yuanmouensis igen. et. isp. nov., was established based on distinctive characteristics. Multi-disciplinary analysis, including sediment palynology and lithostratigraphy, helped primarily reconstruct a significant climatic event during the early Pleistocene, coinciding with the emergence of Yuanmou Man during the fourth member of the Yuanmou Formation's deposition. The findings provide insights into coexistence between canids, hyaenas, hominoids, and other fauna, revealing a rich paleoecosystem and food chain in the region's history. This study contributes to understanding the complex ecological dynamics during this period in the Yuanmou Basin.

Nutritional knowledge of in-school adolescents in Sokoto, North-Western Nigeria

Background: Good nutrition knowledge is a modifiable determinant of dietary behaviours and contributes to strengthen the skills and abilities needed to resist the environmental influences leading to poor dietary habits among adolescents. Objectives were to assess the nutrition knowledge of in-school adolescents in Sokoto, Nigeria and associated factors. Methods: A cross-sectional survey of adolescents selected through multistage random sampling. Data was obtained using pre-tested semi-structured interviewer administered questionnaire. Data was analyzed using IBM® SPSS version 25. Results: A total of 389 subjects were recruited with a mean age of 15.46±1.67 SD and most of them 231 (59.4%) were females. Most 300 (77.1%) of the participants were Hausa, 350 (90%) were Muslims, 278 (71.5%) were from the senior class, and majority 360 (92.5%) resided in urban areas. A large proportion 312 (80.2%) of the participants had good knowledge about classes of food. Only 40 (10.3%) had good knowledge of energy rich food. Two hundred and ninety-eight (76.6%) and 89 (22.9%) had knowledge on high protein diet and good fat diet respectively. Only 107 (27.5%) had good knowledge on minerals and vitamins that are good for bone development. Majority 317 (81.5%) and 341 (87.7%) of the respondents knew eating balanced diet is important and could prevent diseases, respectively. Age category (p=0.007) was the only factor that predicted nutrition knowledge. The main source of nutrition information of the adolescents was teachers 336 (86.4%). Conclusions: Respondents had good knowledge of classes of food. There is however, the need to emphasize on teaching adolescents in the study area about specific nutrient providing meals such as energy rich food, good fat, minerals and vitamins.

Building nutritionally meaningful classification for grocery product groups: the LoCard Food Classification process.

Analysing customer loyalty card data is a novel method for assessing nutritional quality and changes in a population's food consumption. However, prior to its use, the thousands of grocery products available in stores must be reclassified from the retailer's original hierarchical structure into a structure that is suitable for the use of nutrition and health research. We created LoCard Food Classification (LCFC) and examined how it reflects the nutritional quality of the grocery product groups. Nutritional quality was considered the main criterion guiding the reclassification of the 3574 grocery product groups. Information on the main ingredient of the product group, purpose of use and carbon footprint was also used at the more granular levels of LCFC. The main challenge in the reclassification was a lack of detailed information on the type of products included in each group, and some of the groups included products that have opposite health effects. The final LCFC has four hierarchical levels, and it is openly available online. After reclassification, the product groups were linked with the Finnish food composition database, and the nutrient profile was assessed by calculating the Nutrient-Rich Food Index (NRFI) for each product group. sd in NRFI decreased from 0·21 of the least granular level to 0·08 of the most granular level of LCFC indicating that the most granular level of LCFC has more homogeneous nutritional quality. Studies that apply LCFC to examine loyalty card data with health and environmental outcomes are needed to further demonstrate its validity.

Complementary feeding practices of caregivers of infants with Down syndrome as compared to caregivers of typically developing infants

Caregiver feeding practices during the complementary feeding period (6 months–2 years) may be particularly important for infants with Down syndrome (DS) as they are at higher risk for later health conditions (e.g., obesity, diabetes) that can be influenced by early feeding practices. However, how well caregivers of infants with DS are meeting infant feeding evidence-based practices is relatively unknown. Caregivers of infants with DS (N = 75) and caregivers of typically developing (TD) infants (N = 66) aged 0–2 years completed an online survey about their infant feeding practices and information sources. Caregiver practices and information sources were statistically compared between groups. Results indicated that there are significant differences in the feeding practices of caregivers of infants with DS when compared to caregivers of TD infants. Caregivers of infants with DS were less likely to meet infant feeding evidence-based practices than caregivers of TD infants. Caregivers of infants with DS were also more concerned about their infant's food intake and later weight status. Some individual feeding practices also significantly differed between groups, with caregivers of infants with DS more likely to meet evidence-based practices of purchasing iron rich foods and avoiding added salt, but less likely to use responsive feeding practices than caregivers of TD infants. Caregivers of infants with DS were also less likely to receive information about how to navigate the complementary feeding period than caregivers of TD infants. Coupled with existing research, the results of the present study suggest that infant feeding evidence-based practices should be reviewed for their appropriateness for this population and additional support for caregivers of infants with DS should be implemented to help them navigate this important period.

Integrated transcriptomic and lipidomic analysis provides key insights into lipid content changes during pecan (Carya illinoensis) fruit development.

Pecans [Carya illinoinensis (Wangenh.) K. Koch] are highly valued for their abundance of quality healthy lipids, positively impacting human health and making themselves a preferred choice for nutritionally rich foods. However, a comprehensive understanding of the high-resolution characteristics of pecan fruit lipid composition and its dynamic changes, as well as the transfer between embryo and pericarp during development, remains incomplete. In this study, through integrated multi-omics analysis, we observed significant spatiotemporal heterogeneity in lipid changes between the pericarp and embryo. It showed smaller fluctuations and more stable lipid levels in the pericarp while exhibiting a dynamic pattern of initially increasing and then decreasing lipid content in the embryo. In this study, a total of 52 differentially expressed genes were identified, related to fatty acid synthesis and metabolism pathways in the two tissues, with changes in oleic acid and linoleic acid composition being the primary features of the embryo. This research lays the foundation for further understanding the differential regulation mechanisms of lipid metabolism between embryo and pericarp. Overall, this study filled the knowledge gap regarding dynamic changes in pericarp lipid metabolites, provided crucial insights into the lipid metabolism network during pecan fruit development, and established a scientific basis for the genetic improvement of pecan crops.

The effect of motivation type on intake and nutritional status of vitamin B12, omega-3 fatty acids, iron and nutrition knowledge in individuals following a vegan diet

The fundamental principle of veganism is to avoid all possible animal exploitation and therefore, animal ethics has always been a primary motivator. Nowadays, the environment and health are also common motivators. Omission of all animal products leads to dietary exclusion of vitamin B12, limited intake of omega-3 fatty acids, specifically EPA and DHA, and intake of low bioavailable iron sources1. Obtaining the knowledge to appropriately plan and replace nutrients through food or supplementation is key to avoiding deficiencies and subsequent consequences. This study aimed to determine the effect of motivation for being vegan on intake of key nutrients and nutritional knowledge. This cross-sectional, observational study recruited participants, who had followed a vegan diet for minimum 2 years. Demographics and nutrition knowledge were obtained from questionnaires. Motivation type was determined using the validated vegetarian eating motives inventory (VEMI) – participants scored the importance of animal ethic, environment and health. Intakes of vitamin B12 and iron, were collected using a 4-day food diary and assessed against Estimated Average Requirement (EAR). Blood samples were taken to determine status of vitamin B12, haemoglobin, serum ferritin, and omega-3 index. Omega-3 index score ≤4 indicates increased risk of coronary heart disease. Animal ethics was the greatest motivator to become vegan, with 83.5% of participants scoring it as very important, compared to 71.7% of people stating the environment, and 53.3% stating health. No association was found between all motivation types and intake of vitamin B12 and iron, nor omega-3 index. Mean vitamin B12 intake (supplements excluded) of 2.11ug/day ± 3.43 exceeded the EAR of 2.0ug/day for both men and women, however intakes ranged between 0.00 and 37.63ug/day. Mean intake of iron (18.77mg/day) exceeded the EAR for both men and women. Overall mean omega-3 index was 3.16%. Both men (162.24g/L) and women (151.44g/L) had adequate mean Hb serum concentrations. Mean serum ferritin was within normal range for both men (64.86ug/L ± 43.48) and women (32.55ug/L ± 26.04). Overall mean serum vitamin B12 was within normal range (316.54pmol/L ± 146.18), however a large range was observed from 72.00pmol/L to 1,015pmol/L. Males and females had similar knowledge, with only one question regarding fibre content in cornflakes found to be significantly different (P = 0.012). Knowledge was varied e.g., 100% of participants could identify that pasta was a carbohydrate source, yet could not identify which fats are most important to reduce. Mean vitamin B12 intake exceeding EAR and normal status despite limited vegan sources, indicates high consumption of high bioavailable fortified foods, and supplementation. Iron status shows large consumption of iron rich foods to overcome bioavailability issues, reflected by adequate iron intake, after increasing EAR by 80% to meet recommendations. The mean omega-3 index shows a low cardioprotective omega-3 fatty acid intake.

Feeding our Future: school food and local agriculture in the Pacific

Utilising local and traditional foods in schools presents a significant opportunity within our region to ensure food and nutritional security, support local livelihoods by driving markets and employment opportunities, increasing food literacy, and help students to understand the role of, and develop a preference for these foods. School meals programs (SMP) are increasingly touted as a strategy for food system transformation(1), however, are not widely used in the Pacific Islands(2). Yet, there is increasing interest and momentum towards understanding school food and nutrition environments and the use of SMP in this region, especially with models that support and promote the integration of local, traditional climate-resilient, nutrient rich foods. When a large scale SMP may not be possible, other school food and nutrition activities can be utilised to support nutritious food choice. Evidence collected over the last five years provides information on the current situation, activities, and capacity for providing food in schools across the Pacific Islands (2,3,4). Activities across the region vary from national SMP to gardening programs, nutrition education, providing canteens/tuckshops and other ad hoc activities, for example events for World Food Day. Some activities have a requirement for the use of local food, while some prioritise local foods in gardening programs and work with local farmers. Recently it has been shown that youth are exposed to, and have access to significant amounts of ultra-processed foods (UPF) around schools(3). Mapping of the foods available to students within a 400m radius of 88 schools in Fiji found that sugar sweetened beverages were available in 80%, and lollies/confectionary in just over 60% of outlets. Fresh fruit was available in just over 20% of outlets, while fresh vegetables were available in less than 20% of outlets(3). While there are many challenges to providing local, traditional, nutritious foods in schools, including access to financial, human, and physical resources, stakeholders have told us that one of the most significant is how modernisation and colonisation of food systems have resulted in a preference for hyperpalatable UPF and how this makes it more challenging to incorporate local produce in a way that is accepted by students. This provides an opportunity to further explore and share ways to integrate local, traditional, climate-resilient, nutrient rich foods in schools to support children and adolescents to value, utilise, prefer, and advocate for these foods. There is a need to support the utilisation of traditional, local foods in schools by advocating for policy (at various levels, right from a school level upwards) that drives the use of these foods and creates more supportive school food environments.

Assessment of omega-3 and omega-6 fatty acid profiles and ratio of omega-6/omega-3 of white eggs produced by laying hens fed diets enriched with omega-3 rich vegetable oil

Abstract The aim of this study was to evaluate the levels of omega-3 (n-3) and omega-6 (n-6) fatty acids in egg and the ratio of n-6/n-3 of white eggs produced by laying hens (Hy-Line white) fed diets enriched with n-3 fats. In this study, alpha-linolenic acid (ALA) levels of the dietary treatments ranged from 0.3 to 6% energy. Grain-based diets containing a low linoleic acid (LA) content were selected to prepare a basal diet to optimize the conversion of ALA into n-3 long chain polyunsaturated fatty acids (LCPUFA). The results showed that the level of all n-3 LCPUFA in eggs improved (P &lt; 0.01) by increasing the levels of dietary ALA. Importantly, eggs produced from laying hens fed diets containing 6%en ALA significantly increased (P &lt; 0.01) the total of n-3 fats by approximately nine-fold. Diets enriched with ALA significantly reduced (P &lt; 0.01) the ratio of n-6/n-3 of the eggs. The n-6/n-3 ratio of eggs decreased from 7.17% in the 0.3%en ALA diet to 1.29% in the 6%en ALA diet. In conclusion, white laying hens fed ALA-enriched diets produced eggs higher in n-3 fatty acids and lower n-6/n-3 ratio, which provides an alternative n-3 rich food for consumers and have beneficial health effects.

Immunity Patterns of Covid-19 Recovered Patients in Gilgit Baltistan, Pakistan

The main purpose of this study was to assess the immunity of recovered patients in COVID-19 patients. The idea was to unveil the nexus between the onset of COVID-19 coupled with the virulence of the disease and the immune responses of the target population in tandem with the intake of local/traditional foods. In the current study antibody presence and complete blood profile of 100 individuals were studied for COVID-19, from the Gilgit area. Immunity against COVID-19 recovered patients was observed during this investigation after more than eight months of their recovery. In this study, 78.2% of people were positive for Immunoglobin G antibody and 23.7% for Immunoglobin M antibody. The most infected age group recorded was 31-40 years. The mean blood glucose level in random was 143.38 mg/dL and 128.18 mg/dL in males and females, respectively. The mean cholesterol level in males was 148.82 mg/dL while the female cholesterol mean was 126.49 mg/dL. White Blood Cells were observed within their prescribed ranges. The mean hemoglobin level was 14.580 g/dL and 12.022 g/dL while mean RBC was 4.7838×106 m/µL and 4.2993×106 m/µL and the mean platelets were 238.45×103/µL and 261.91×103/µL in male and female, respectively. It is observed that the A+ blood group was more susceptible to infection. About 75% of individuals consume highly rich and nutritious food. About 55% of people engaged themselves with exercise. 25% of participants used their normal regular diet during the infection phase on the other hand 75% of individuals treated themselves with a specific and highly nutritious diet for their rapid and healthy recovery. More than 65% of people were re-infected after COVID-19 vaccination but the symptoms were not severe. Due to the strong innate immunity of people from this region, they recovered more rapidly. The dietary habits, high hemoglobin levels coupled with regular exercise might have a positive impact on early recovery of COVID-19-infected patients.

A Brief Outline of Navigation on the Black and Azov Seas from Antiquity to the Russian Regular Fleet

Based on the principles of historicism and consistency, the article examines the stages of navigation in the Azov-Black Sea basin from early antiquity to the Russian regular Navy. Little-known written and material sources were used. The evolution of sailing and rowing vessels is shown, due to the tasks of certain periods and the technological capabilities of the subjects. The constant attractiveness of the Azov Sea and the mouth of the Don River with adjacent lands as sources of rich food resources and as a crossroads of world trade routes for very remote states for thousands of years has been revealed. The decisive role of motivation, technical and professional training of naval potential in ensuring the military and economic success of participants in the competitive historical process is shown. The political and economic expediency and firm consistency of Russia in gaining access to the South Seas, which culminated in the implementation of Peter the Great's Azov project, are emphasized. Using concrete examples, the effectiveness of the principle of historicism in scientific and practical reconstructions of voyages on replica ships of the past is demonstrated. It is concluded that in order to acquire the proper level of national consciousness, Russians need systematic historical education and enlightenment.

Insights into carbonate environmental conditions in the Chukchi Sea

Abstract. Healthy Arctic marine ecosystems are essential to the food security and sovereignty, culture, and wellbeing of Indigenous Peoples in the Arctic. At the same time, Arctic marine ecosystems are highly susceptible to impacts of climate change and ocean acidification. While increasing ocean and air temperatures and melting sea ice act as direct stressors on the ecosystem, they also indirectly enhance ocean acidification, accelerating the associated changes in the inorganic carbon system. Yet, much is to be learned about the current state and variability of the inorganic carbon system in remote, high-latitude oceans. Here, we present time series (2016–2020) of pH and the partial pressure of carbon dioxide (pCO2) from the northeast Chukchi Sea continental shelf. The Chukchi Ecosystem Observatory includes a suite of subsurface year-round moorings sited amid a biological hotspot that is characterized by high primary productivity and a rich benthic food web that in turn supports coastal Iñupiat, whales, ice seals, walrus (Odobenus rosmarus), and Arctic cod (Boreogadus saida). Our observations suggest that near-bottom waters (33 m depth, 13 m above the seafloor) are a high carbon dioxide and low pH and aragonite saturation state (Ωarag) environment in summer and fall, when organic material from the highly productive summer remineralizes. During this time, Ωarag can be as low as 0.4. In winter, when the site was covered by sea ice, pH was &lt;8 and Ωarag remained undersaturated under the sea ice. There were only two short seasonal periods with relatively higher pH and Ωarag, which we term ocean acidification relaxation events. In spring, high primary production from sea ice algae and phytoplankton blooms led to spikes in pH (pH &gt; 8) and aragonite oversaturation. In late fall, strong wind-driven mixing events that delivered low-CO2 surface water to the shelf also led to events with elevated pH and Ωarag. Given the recent observations of high rates of ocean acidification and a sudden and dramatic shift of the physical, biogeochemical, and ecosystem conditions in the Chukchi Sea, it is possible that the observed extreme conditions at the Chukchi Ecosystem Observatory are deviating from the carbonate conditions to which many species are adapted.

The dynamics in food selection stemming from price awareness and perceived income adequacy: a cross-sectional study using 1-year loyalty card data

BackgroundHigher cost of healthy foods may explain unhealthy dietary patterns in lower-income households. Unfortunately, combining food selection and nutrient intake data to price and expenditure is challenging. Food retailer’s customer loyalty card data, linked to nutrient composition database, is a novel method for simultaneous exploration of food purchases, price, and nutrition. ObjectivesWe studied the associations between perceived income adequacy (PIA) as a grouping variable with price (per kilogram or megajoule) and the volume of purchases (percentage of expenditure or energy) simultaneously as outcome variables for 17 most purchased food groups. MethodsWe used 1-year (2018) loyalty card data from the largest grocery chain in Finland. Participants were 28,783 loyalty cardholders who made ≥41% of food purchases from the retailer and answered an online questionnaire at the midpoint of data collection. The 5-level PIA described the perceived financial situation in the household. Energy and nutrient content of foods purchased were from the Finnish Food Composition Database Fineli. We calculated the Nutrient Rich Food Index per 100 g food using 11 nutrients. Trends in prices and expenditures between PIA levels were analyzed using 2-sided Jonckheere–Terpstra tests, with false discovery rate control (Benjamini–Hochberg method) and confounder adjustments (inverse probability weighting). ResultsLower PIA participants selected cheaper foods per kilogram and megajoule within most food groups. They also favored unhealthy food groups cheap in energy [<1 € (USD 1.18)/MJ]. Despite lower purchase price, the expenditure (%) among lower PIA was higher on alcohol, snacks, sugar-sweetened beverages, and sweets and chocolates. ConclusionsParticipants with lower PIA showed stronger price awareness. It is crucial to consider the pricing of competing alternative food groups, when steering toward environmentally sustainable and healthier food purchases. Package labeling might also direct the selection of healthier choices among the less expensive items within a food group.

(206) Strategies of Nitric Oxide Augmentation for PDE5 Inhibitors

Abstract Introduction Erectile function and endothelial functions are closely related entities. Nitric oxide NO regulates circulation and microcirculation involved in erection.NO concentration is reduced with aging, diabetes, environment pollution smoking, obesity, inflammation, high prolactin, low testosterone oxidative stress and atherosclerosis. Many of erectile dysfunction patients are PDE5 inhibitor resistant. Strategies to enhance NO expression, can be employed to convert treatment resistant patient into responder. Objective Employ every possible mechanism to augment nitric oxide expression. Greater base line nitric oxide better would be PDE5 inhibitor respose. Methods Internet search was made on various website including pub med, science direct, google scholars using key words like erection, erectile dysfunction, nitric oxide, l arginine, oxidative stress, antioxidant, NOS, endothelial dysfunction, atherosclerosis and etc. This was followed by literature study on given topic. Results Efficacy of PDE 5 inhibitor in ED treatment is 70%. NO concentration decline to 50% by age of 40 and is only 15% at age 60. Humming can increase nasal NO level up to 15 time. Conclusions NO regulates endothelial function, vasodilatation, platelet aggregation inhibition, free radical scavenging, testosterone synthesis and neuronal protection. Study of mechanism of NO production provides, strategies for its enhancement. L arginine, L citrulline, serve as substrate and vitamin C, tetrahydrobiopterin (BH4) act as co factors in production of NO. Endothelial nitric oxide synthase e NOS, neuronal nitric oxide synthase n NOS are major enzymes act involved in synthesis. Oxygen is required for NO synthesis process. Supplementation of substrate and cofactors help increase NO levels. Oxygen availability can be increased through exercise and raising hemoglobin level. Reactive oxygen species ROS convert NO into bioinactive peroxynitrite which itself is ROS. Oxidative stress can cause endothelial nitric oxide synthase uncoupling. Consequently eNOS start producing ROS. This causes oxidation of NOS and as well as of cofactor like BH4 and vitamin C. ROS also increase level of methylarginines. Antioxidant used to neutralize ROS include Co Q10, alpha lipoic acid, flavonoids, bioflavonoids poly phenols, pycnogenol, resveterol, fulvic acid and etc. Second mechanism NO production is from dietary nitrates. Nutritional nitrates are converted into nitrite by oral anaerobic bacteria’s. Nitrate rich foods like beet root or spinach are added to enhance nitrate based NO. Nitric oxide thus produced is used for vasodilatation of penile vessels as well sinuses of corpus cavernousm. Apart from that it inhibits uncoupling of NOS. This support L arginine based mechanism of NO production. Nitroglycerin or minoxidal act as NO donors. These agents can be used locally at glans penis to augment NO availability. Bee breathing is maneuver in which humming sound vibrates nasal sinus increasing NO production up to 15 folds. Inhaled NO act as bronchodilator which increase lung capacity leading to higher blood oxygen concentration. Various NO enhancement strategies thus applied, may convert non responder PDE5 inhibitor to responders. Disclosure No.

Impact Assessment of Iron and Folic Acid Supplementation with and Without Intensive Health Education in Pregnant Women of Rural Area of District Etawah: An Interventional Study

Background: Low birth weight , post-partum haemorrhage still births and maternal deaths are associated with anaemia in pregnancy. If prevalence of anemia will be reduced then there will be improvement in maternal and child health and its outcome. Aim &amp; Objectives: To evaluate the changes in the hematological profile of the study subjects and to determine the impact of intensive health education intervention on anemia status of pregnant women. Methodology: A Community based interventional study was conducted among 200 Pregnant women of selected villages in rural area of Etawah district (100 women in each interventional and non-interventional group) using a self-developed, pre designed, pretested, structured and validated questionnaire. statistical package for social sciences (SPSS) software was used to analyse the data. Result: After health education intervention there is significant increase in the haematological profile of study participants of interventional group (p&lt;0.05) as before intervention values of mean Hb was 10.58±1.79 gm/dl which became 11.72±1.48 gm/dl There were 34 (73.9%) participants in the interventional group that were originally anaemic before the study, but after the intervention, they became non-anaemic. Conclusion: Health education sessions helped the pregnant women to improve their knowledge regarding anemia in pregnancy, as well as improve their ability to select iron rich foods, increase compliance with iron supplementation, and raise their haemoglobin levels.

Linear association of compound dietary antioxidant index with hyperlipidemia: a cross-sectional study.

There is growing evidence that antioxidant-rich diets may prevent hyperlipidemia. However, the relationship between the Composite Dietary Antioxidant Index (CDAI) and hyperlipidemia is unclear. The CDAI is a composite score reflecting the antioxidant content of an individual's diet, and this study aimed to investigate the relationship between CDAI and hyperlipidemia. The study used the 2003-2018 National Health and Nutrition Examination Survey (NHANES) database for cross-sectional analyses and included 27,626 participants aged 20 years and older. The CDAI, which includes vitamins A, C, and E, zinc, selenium, and carotenoids, was calculated based on dietary intake reported in a 24-h recall interview. Hyperlipidemia was defined by the National Cholesterol Education Program (NCEP). Covariates included age, sex, race, education, marriage, household poverty-to-income ratio (PIR), glomerular filtration rate (eGFR), body mass index (BMI), energy, carbohydrates, total fat, cholesterol, smoking, alcohol consumption, hypertension, diabetes mellitus, coronary heart disease, and lipid-lowering medications. The association between CDAI and hyperlipidemia was explored through multiple logistic regression analyses and smoothed curve fitting. We also performed subgroup analyses and interaction tests to verify the relationship's stability. After adjusting for potential confounders, CDAI was negatively associated with the risk of developing hyperlipidemia (OR 0.98, 95% CI 0.96-0.99, p < 0.01). The results of weighted regression models stratified by quartiles of CDAI (-8.664 ≤ Q1 ≤ -2.209, -2.209 < Q2 ≤ -0.002, -0.002 < Q3 ≤ 2.774, 2.774 < Q4 ≤ 124.284), fully adjusted for confounding variables, indicated that compared with the bottom quartile (Q1) of the CDAI, Q2, Q3, and Q4 of participants had a lower advantage ratio (Q2: OR 0.91, 95% CI 0.78-1.06, p < 0.21; Q3: OR 0.85, 95% CI 0.73-1.00, p < 0.05; and Q4: OR 0.77, 95% CI 0.64-0.94, p < 0.01), which was confirmed by a test for trend (p < 0.05). Smoothed curve fit analysis showed linearity (p for non-linear = 0.0912). In summary, there is a linear negative relationship between CDAI and the risk of developing hyperlipidemia. Subgroup analyses by age, sex, ethnicity, education level, marriage, tobacco status, alcoholic drinking, body mass index (BMI), hypertension, and diabetes did not indicate strong interactions. In this large cross-sectional study, there was a linear negative association between CDAI and hyperlipidemia among US adults. Therefore increase antioxidant rich foods in your life as a prevention of hyperlipidemia.

Ecological interactions between farmed Atlantic salmon and wild Atlantic cod populations in Norway: A review of risk sources and knowledge gaps

AbstractAquaculture provides an important and expanding source of protein rich and healthy food to the world. However, to minimize environmental harm from aquaculture, interactions with wild fish communities need to be thoroughly assessed. Here, we characterize the existing knowledge pertaining to such interactions, exemplified with Atlantic salmon (Salmo salar) farming in open net pens along the Norwegian coast and potential consequences for wild Atlantic cod (Gadus morhua) populations. Importantly, the wild cod fishery also provides a protein rich, high quality food source with high economic value. We identify seven risk sources that may affect behaviour, physiology, and survival in wild cod. Of particular importance is the large amount of waste feed that causes wild fish to aggregate around farms, thereby altering a multitude of ecological interactions including predation and disease transmission. Moreover, altered food quality in pellets may alter physiological processes and cause mortality to vulnerable life‐stages in wild cod. More research is needed on mechanisms and thresholds for harm. As the most important cod fisheries are found in northern Norway, where climate change also is rapid, we expect stronger and potentially more harmful interactions between fish farming and wild cod fisheries as aquaculture continues to expand. We hope that our analysis will inspire further research, on farmed salmon and wild cod interactions, but also on aquaculture and wild fish interactions in general. Such research is fundamental for the development of management systems that can reduce the impact of aquaculture on fisheries and the environment.

Sustainability Evaluation of Plant-Based Beverages and Semi-Skimmed Milk Incorporating Nutrients, Market Prices, and Environmental Costs

Developing a reliable method to compare food sustainability is gaining traction, with efforts like those by the Food and Agriculture Organization (FAO). This research aims to contribute to a comprehensive scientific comparison of food categories based on CO2 emissions linked not to weight but to their primary function: nutrient availability and uptake in the consumer’s body. The study utilizes a multi-criteria evaluation for sustainability, incorporating the Nutrient Rich Food (NRF) score, protein digestibility, and essential amino acid content. A case study compares one serving of semi-skimmed milk (SSM) with various plant-based beverages (oat, soy, rice, coconut, and almond), considering their carbon footprints in relation to nutrient content and environmental costs. The analysis integrates protein quality through essential amino acid proportion and digestibility. Findings reveal that achieving an NRF11.3 score of 50 requires more servings of unfortified plant-based beverages than semi-skimmed milk, resulting in higher carbon footprints, except for soy drink. However, when considering emerging farm management measures, semi-skimmed and soy drinks show comparable carbon footprints for a given NRF score. Fortified plant-based beverages (soy, oat, and almond) exhibit lower footprints relative to the calculated NRF scores. Yet, when converting carbon footprints to euros using the European Union Emissions Trading System and adding them to retail prices per kilogram, semi-skimmed milk emerges as the option with the lowest “societal costs” (environment and consumer costs). The research underscores that understanding a food product’s nutritional value requires more than knowledge of its composition; uptake into the body maintenance and potential synergistic effects of other components in the food matrix play crucial roles.
