Abstract:
Despite trace elements and vitamins are major public health problems in some African countries, there are few studies reporting micronutrient status in North Africa. Therefore, it could be interesting to evaluate plasma concentrations of vitamin A, E and beta-carotene, along with zinc, copper, selenium erythrocyte glutathione peroxidase and superoxide dismutase in Algeria. Volunteers were randomly recruited in Constantine, Batna and Mila. Vitamins, trace elements and enzymes were measured in the University Hospital of Grenoble. 455 persons were included in the study. Subjects were divided in 3 groups: group I: 15 girls and 12 boys who were 6 to 12.9 years old, group II: 190 women and 192 men 13 to 49.9 years old, group III: 24 women and 24 men 50 to 65 years old. Plasma concentrations of micronutrients and enzymes are close to those commonly observed in Europe, except for vitamin A concentrations. Indeed, retinol levels are 30–35% lower than those reported in European countries, moreover almost 8% of the population showed retinol concentrations less than 1.05 mumol/l. Beta-Carotene levels were also lower than in the French average population. Ten per cent of the population had plasma zinc levels lower than 10.6 mumol/l. Vitamin E, copper and selenium status seems satisfactory in Algeria. Vitamin A is not a public health problem, however a significant percentage of residents exhibits impaired vitamin A levels and may benefit from retinol supplementation. Larger studies are needed, and particularly in children, to detect possible higher prevalence of vitamin A deficiency in poor socio-economical classes and in inner geographic areas.

Abstract:
A healthy diet is a factor in maintaining and improving health, helping to reduce the risk of developing alimentary-dependent diseases. The article presents the causes of malnutrition, data on the actual deficiency of vitamins and minerals in the population of the Russian Federation. Insufficient content of essential micronutrients in the diet is accompanied by a decrease in the body’s adaptive capabilities, contributing to an increase in the risk of developing non-infectious diseases. The article provides information on the role of chronic low-level inflammation and oxidative stress in the development of noncommunicable diseases. Significant contributors are vitamin D, zinc and selenium, and their deficiencies are widespread. Scientific evidence supports the role of vitamin D, zinc, selenium in the development of non-infectious diseases. The review discusses the role of vitamin D in the development of cardiovascular disorders, discusses the dependence on iron and zinc, which has clinical diagnostic and therapeutic value in anaemia and associated pathological conditions. In addition, the article discusses selenium and zinc deficiencies with the risk of the coronary syndrome, stroke, cardiovascular disease and mortality from them. Despite conflicting data on the effectiveness of oral micronutrient supplementation to prevent and treat chronic noncommunicable diseases, healthcare providers should be informed about the consequences of micronutrient deficiencies and identify micronutrient deficiencies correct them. This is important in treatment and prevention activities for people at risk, especially in endemic disadvantaged regions. The literature search was carried out in the databases PubMed, CyberLeninka, e-library.

ABSTRACT Objective To evaluate the intake of antioxidant nutrients by pregnant women being cared for in the Brazilian public health system and associated factors. Methods A cross-sectional study was carried out with pregnant women cared for in the public health system in the city of Maceió, Brazil, in 2014, including 385 pregnant women and their newborns, and the collection of maternal information (socioeconomic, personal, prenatal, dietary and anthropometric data), and after the babies’ birth (gestational age, birth weight and length). Food intake was assessed by two 24-hour dietary reminders per pregnant woman with subsequent adjustments by the Estimated Average Requirement method. Data were processed and Pearson’s correlation was used to evaluate associations, considering p<0.05 as significant. Results A total of 388 pregnant women with a mean age of 24.06±5.92 years were studied, with inadequate intake and high variation of the following antioxidants: vitamin A (83.2%/62.7%), vitamin C (50.5%/75.7%), vitamin E (76.5%/60.2%), Selenium (60.8%/50.3%), Copper (98.5%/42.8%) and Zinc (79.6%/43.4%), respectively. Additionally, the following associations were observed: the intake of vitamin A (p=0.02), Copper (p=0.01), and Selenium (p=0.01) with the maternal Body Mass Index; the intake of vitamin A (0.04) and Selenium (p=0.02) with the birth weight; and between vitamin A (p=0.04) with the birth length. Conclusion The low intake of antioxidant nutrients by pregnant women is a reality, being associated to the maternal Body Mass Index and the birth weight and length of the newborn.

AbstractBackgroundInformation is needed on dietary adequacy of Arctic indigenous populations in Canada. Extensive work has been completed on composition of Arctic food and food use, and dietary reference intakes are available.ObjectiveTo complete the first comprehensive dietary adequacy assessment of three populations of adult Arctic indigenous people.Setting and subjectsDietary assessment interviews were conducted with randomly selected indigenous adults during two seasons in 44 representative communities of Yukon First Nations (n= 797), Dene/Métis, (n= 1007) and Inuit (n= 1525).MethodsTwenty-four-hour recalls were used to derive adjusted distributions of usual nutrient intakes in four age/gender groups for assessment of dietary adequacy for carbohydrate, dietary fibre, protein,n–3 fatty acids,n–6 fatty acids, calcium, copper, iron, magnesium, manganese, phosphorus, selenium, zinc, vitamin A, riboflavin, folate, vitamin B6, vitamin C, vitamin D and vitamin E.ResultsNutrients with high prevalence of adequacy for most age/gender groups in all three cultures were protein, carbohydrate,n–3 fatty acids, iron, copper, zinc, manganese, selenium, riboflavin and vitamin B6; some individuals exceeded the upper intake level for iron, zinc, selenium, vitamin A and vitamin D. Estimated average requirement nutrients of concern for adequacy were magnesium, folate, vitamin A, vitamin C and vitamin E; however, a few age/gender groups were exceptions. Prevalence of inadequacy for AI nutrients which may be undesirably high were fibre,n–6 fatty acids and calcium. Vitamin D was more adequate in Inuit women and men than for Yukon First Nations or Dene/Métis.ConclusionsUnique patterns of dietary adequacy exist among Arctic indigenous peoples. Local wildlife food sources and market food sources should be maximised for their nutrient contributions to Arctic diets.

Abstract:
In the review article the authors discuss unsolved issues regarding vitamin and mineral support of patients undergoing bariatric/metabolic operations. Many patients refer for the surgery already having deficiencies of macro- and micronutrients and need preoperative preparation for improving of vitamin-mineral status. Vitamin-mineral support is indicated after each bariatric operation, however the volume of nutritive support and the choice and doses of vitamins and minerals can be varied depending on type of surgery. Hypoabsorptive procedures such as duodenal switch or SADI-S (Single anastomosis duodenoileal bypass with sleeve gastrectomy) usually demand more significant protein, calcium and iron supplementations together with administration of multivitamin complexes containing fat-soluble vitamins. Existing standard vitamin-mineral complexes may not contain necessary doses of iron, calcium, fat-soluble and other vitamins as well as some microelements like cooper, zink, selenium etc. Thus, sufficient vitamin-mineral support may need up to 10 tablets or pills daily depending on kind of surgery. That can influence on patients compliance, lead to refusal of supplementations and thus to undesirable metabolic consequences after surgery. The authors have concluded about necessity of working out of cost-effective domestic series of vitamin-mineral combinations with high bio-availability specially adapted to every class of bariatric/metabolic operation. To authors opinion this can lead to better patients compliance and can prevent undesirable side effects after metabolic surgery.

Abstract:
Background: The novel coronavirus (COVID-19) is considered as the most life-threatening pandemic disease during the last decade. The individual nutritional status, though usually ignored in the management of COVID-19, plays a critical role in the immune function and pathogenesis of infection. Accordingly, the present review article aimed to report the effects of nutrients and nutraceuticals on respiratory viral infections including COVID-19, with a focus on their mechanisms of action. Methods: Studies were identified via systematic searches of the databases including PubMed/ MEDLINE, ScienceDirect, Scopus, and Google Scholar from 2000 until April 2020, using keywords. All relevant clinical and experimental studies published in English were included. Results: Protein-energy malnutrition (PEM) is common in severe respiratory infections and should be considered in the management of COVID-19 patients. On the other hand, obesity can be accompanied by decreasing the host immunity. Therefore, increasing physical activity at home and a slight caloric restriction with adequate intake of micronutrients and nutraceuticals are simple aids to boost host immunity and decrease the clinical manifestations of COVID-19. Conclusion: The most important nutrients which can be considered for COVID-19 management are vitamin D, vitamin C, vitamin A, folate, zinc, and probiotics. Their adequacy should be provided through dietary intake or appropriate supplementation. Moreover, adequate intake of some other dietary agents including vitamin E, magnesium, selenium, alpha linolenic acid and phytochemicals are required to maintain the host immunity.

Abstract:
One randomized, prospective clinical trial for chemoprevention of prostate cancer has been completed, and two additional trials are ongoing. The investment, time, and effort for these trials are substantial. We reviewed the outcomes of these trials to address the value of the investment. The outcomes of the Prostate Cancer Prevention Trial (testing finasteride) and the design of the Selenium and Vitamin E Cancer Prevention Trial (SELECT; testing vitamin E and selenium) trial as well as the Reduction by Dutasteride of Prostate Cancer Events (REDUCE) trial (testing dutasteride) were reviewed. From a public health standpoint, there is tremendous potential for benefit from large-scale cancer prevention trials. Because of the volume of data that are collected, potential discoveries related to the biology of the disease are substantial. Translational scientific efforts are direct outgrowths of these studies. Prospective, randomized chemoprevention trials for prostate and other cancers are expensive and require long periods of time to conduct, yet the rewards are on a par with the investment.

Abstract:
AbstractObjective:Malnutrition in drug abusers has been attributed to poor diet. However, previous studies are conflicting. Many studies have not considered possible concurrent HIV disease. The purpose of this study was to determine the relationship between drug abuse and dietary intake in Hispanic Americans with and without HIV infection.Design:Dietary intake was measured using 3-day food records and 24-hour dietary recalls in three groups: HIV-positive drug abusers, HIV-negative drug abusers and HIV-positive persons who do not use drugs (‘non-drug abusers’).Setting:The baseline data from a prospective cohort study of the role of drug abuse in HIV/AIDS weight loss and malnutrition conducted in Boston, Massachusetts, USA.Subjects:The first 284 participants to enrol in the study.Results:HIV-positive drug abusers had a body mass index (BMI) that was significantly lower than that of HIV-positive non-drug abusers. Reported energy, fat and fibre intakes did not differ between groups. All groups had median reported intakes of vitamin A, vitamin B6, vitamin B12, selenium and zinc that were in excess of the dietary reference values (DRI). Intakes of α-tocopherol were below the DRI, but did not differ from intakes of the general US population. However, increasing levels of drug abuse were associated with lower reported intakes of vitamin B6, vitamin B12, selenium and zinc.Conclusions:Overall, this study does not support the notion that dietary intake can explain the lower BMI of HIV-positive drug abusers. Further studies examining non-dietary determinants of nutritional status in drug abusers are warranted.

Abstract:
Background: Studies of gingival bleeding and the effects of antioxidants on extracellular matrix and immunologic and inflammatory responses provide a rationale for hypothesizing that antioxidants reduce the risk for gingival bleeding.Methods: This study evaluated the role of antioxidants as contributing risk factors for gingival bleeding utilizing the Third National Health and Nutrition Examination Survey (NAHNES III). A sample of 18,825 adults (20 to ≥ 90 years of age), with dental measurement and assessment of serum levels of antioxidants were included in the study. Gingival bleeding was defined as those who had more than 30 percent of gingival bleeding in 28 sites examined. SPSS version 11.0 software and Epi-info 2000 were used to perform the statistical analysis.Results: Using multiple logistic regression in five separate antioxidants, the study showed an association between increased plasma levels of vitamin C (ascorbic acid) and decreased risk for gingival bleeding (OR= 0.33; 95% CI 0.15 to 0.72). An inverse relationship was also found between gingival bleeding and serum levels of beta carotene (OR=1.93; 95% CI 1.05 to 3.54). However, negative association was found between gingival bleeding and vitamin A (OR=2.60; 95% CI 1.04 to 6.50). No statistically significant association was observed between gingival bleeding and serum levels in vitamin E (alpha tocopherol) and selenium.Conclusion: Antioxidants, vitamin C, vitamin A, and beta carotene, were significant risk factors for gingival bleeding. This should be emphasized for improving the oral health of the U.S. adult population.

Abstract:
A indústria avícola brasileira representa uma atividade econômica muito importante para o país. Recentemente, uma lesão muscular localizada cranialmente no dorso de frangos de corte, vem causando grandes perdas econômicas devido à condenação de carcaças. Machos de linhagens pesadas, com as maiores médias de peso e idade de abate apresentam as maiores freqüências de condenação devido à referida lesão. As lesões são caracterizadas por amarelamento e inchaço da pele que recobre o músculo lesado. Após abertura da pele, pode-se notar edema subcutâneo, hemorragia muscular superficial, palidez, aderência, aumento da espessura e consistência envolvendo sempre o músculo anterior latissimus dorsi. Histologicamente a lesão é polifásica e inclui variação no tamanho e partição das fibras (splitting), degeneração hialina, necrose, regeneração e intensa fibrose com presença de adipócitos e infiltrado linfohistiocitário. A etiologia desta miopatia é desconhecida e não há publicações detalhadas a respeito na literatura consultada. Os objetivos do presente trabalho foram detectar a etiologia da miopatia dorsal cranial através da realização de alguns experimentos, bem como, verificar se a lesão apresenta um potencial risco à saúde pública Para atender esses objetivos foram conduzidos experimentos de avaliação da associação entre a miopatia dorsal cranial e a síndrome ascítica; de ausência de inclusão de vitamina E e selênio na dieta de frangos de corte na tentativa de reproduzir a lesão; quantificação de vitamina E (alfa tocoferol) e selênio em músculos lesados e músculos normais; avaliação do papel do exercício na indução da miopatia dorsal cranial bem como sua associação com a miopatia peitoral profunda e também foram realizadas pesquisas de bactérias de interesse em saúde pública em músculos com lesão. Não há risco de intoxicação através do consumo do músculo Anterior latissimus dorsi lesado ou normal em relação às bactérias Sthaphylococcus aureus, Escherichia coli, Salmonella enteritidis Enteritidis, Listeria monocytogenes, Pasteurella multocida, Yersinia enterocolitica, Campylobacter coli e Campylobacter jejuni subsp. jejuni. Os níveis médios de alfa tocoferol e selênio nos músculos anterior latissimus dorsi lesados ou normais são compatíveis com os níveis de carcaças usualmente suplementadas. Músculos com lesão apresentaram níveis mais elevados de selênio do que músculos sem lesão. Pode-se constatar também, a ausência de associações entre a miopatia dorsal cranial e a síndrome ascítica, bem como, à miopatia peitoral profunda. O protocolo de exercício que induziu à frequências altas (96,9%) de miopatia peitoral profunda não reproduziu à miopatia dorsal cranial. A causa ou as causas da miopatia dorsal cranial não puderam ser esclarecidas com base nos experimentos realizados, porém os mesmos permitem concluir que e a ingestão de baixos níveis de vitamina E não está envolvida na etiologia desta miopatia.<br>The Brazilian poultry industry is a very important economic activity to this country. Recently, a dorsal cranial muscular lesion has been occurring in increasing frequency in broilers causing heavy economic losses due to downgrading of carcasses. Males of heavy strains with higher average weight at slaughter had the highest frequency of downgrading due to this lesion. Gross lesions are characterized by yellowish discoloration of the skin and swelling on the dorsal cranial region. When the skin is sectioned, subcutaneous edema, muscular superficial hemorrhage, pallor, adherence, increased thickness and density involving always the anterior latissimus dorsi muscle are seen. Microscopical features include a polyphasic lesion with size variation and fiber splitting, hyaline, necrotic, regenerating fibers and extensive fibrosis and adipose tissue. Lymphohistiocytic infiltration is seen. The etiology of this myopathy is unknown and no detailed report is available in the world literature. The aims of this study were to detect the etiology of the dorsal cranial myopathy by some experiments, as well as to verify if this lesion may pose a potential public health risk. One experiment was designed to assess the association between dorsal cranial myopathy and ascitic syndrome; other experiment attempt to reproduce the lesion with the lack of inclusion of vitamin E and selenium in the diet of broiler chickens; other study was the quantification of vitamin E (alpha tocopherol) and selenium in injured and normal muscles; the evaluation of the role of exercise in inducing the dorsal cranial myopathy and its association with the deep pectoral myopathy; and microbiological studies were done to clarify if infectious agents are present in the affected muscles. There is no risk of poisoning through the consumption of the injured or normal anterior latissimus dorsi muscle in relation to the bacteria Staphylococcus aureus, Escherichia coli, Salmonella enteritidis Enteritidis, Listeria monocytogenes, Pasteurella multocida, Yersinia enterocolitica, Campylobacter coli e Campylobacter jejuni subsp. jejuni. Average levels of alpha tocopherol and selenium in the damaged or normal anterior latissimus dorsi muscle are consistent with carcasses usually supplemented. Injured muscles showed higher levels of selenium than uninjured muscles. The absence of associations between dorsal cranial myopathy and ascitic syndrome, as well as the deep pectoral myopathy was observed. The exercise protocol that induced a high frequency (96.9%) of deep pectoral myopathy did not reproduce the dorsal cranial myopathy. The cause or causes of dorsal cranial myopathy could not be clarified based on these experiments, but is possible to conclude that low intake of vitamin E is not involved in the etiology of this myopathy.

Abstract:
Weaning stress in young calves is often compounded with stress from transport, marketing, and commingling. The result is a weakened immune system, which can lead to increased incidence of diseases, especially bovine respiratory disease complex (BRDC). Backgrounding cattle post-weaning and prior to feedlot entry may alleviate some of the more common stresses and typically diminished feed intake. Five trials were conducted with a total of 228 weaned calves to evaluate different backgrounding systems. Drylot diets with 70:30 and 40:60 forage to concentrate total mixed rations with Se and vitamin E injections were studied. No differences were observed in daily gains or feed efficiency among treatments. Steers receiving Se injections had higher (P < 0.05) blood Se concentrations on d 7, 14, 28, and 42. Steers grazed four types of stockpiled pastures with previous pasture treatments: control, poultry litter fed to previous grazing cattle, poultry litter applied, and inorganic fertilizer. Supplements (16% CP) for each pasture treatment were none, soy hulls + SBM (0.5% BW), and corn + SBM (0.5% BW). On d 7, unsupplemented steers had higher (P < 0.05) daily gains than steers supplemented with corn + SBM. No differences were detected on any other day. Heifers grazed stockpiled fescue and were fed three 16% CP supplements: corn gluten feed + soy hulls (0.5% BW), corn gluten feed + soy hulls (1.0% BW), and soy hulls + SBM (0.5% BW). On d 14, heifers supplemented with soy hulls + SBM had higher (P < 0.05) cumulative daily gains. No other differences were detected in gains among treatments. Steers were allotted to four injection treatments: none, Se, vitamin E, and combination of Se and vitamin E. There were no differences in daily gain or blood Se concentrations on any day among all treatments. Steers grazed two pasture types: fescue and fescue + alfalfa, with the following injections: none, vitamin E, and Se. There were no differences in daily gains among all treatments. On d 7, 14, 28, and 42, steers receiving Se injections had higher (P < 0.05) blood Se concentrations. On d 7 and 14, steers grazing fescue pastures had higher serum alpha-tocopherol concentrations than steers grazing fescue + alfalfa pastures. There were no differences in serum alpha-tocopherol concentrations due to injection treatment on any day. No consistent differences were detected in forage and blood serum mineral concentrations in all trials. There were no differences in gains from by-product supplementation versus â traditionalâ corn-based supplementation, suggesting that by-product feedstuffs may be of value for backgrounding rations. Selenium and vitamin E supplementation did not have any significant effect on calf morbidity.<br>Master of Science

Abstract:
Mercury is an environmental contaminant of concern, particularly for fish eating populations. The objective of this study was to assess the effects of selenium, vitamin E, and phytate on methylmercury (MeHg) toxicity and kinetics in rats. Results show that increased selenium increases McHg in the liver, kidney, and frontal lobe of the brain, while increased vitamin E increases MeHg in the kidney but lowers McHg in the liver. Increased phytate resulted in a significant increase in MeHg in the frontal lobe. Methylmercury-treated rats on all diets showed an increased trend in muscarinic acetylcholine receptor (mAChR) binding in comparison with untreated rats. There was no change in monoamine oxidase (MAO) activities in all treatment groups. These results suggest that nutrients can alter the toxicokinetics of MeHg but none of them show clear protection in neurotoxicity in adult rats.

Methylmercury (MeHg) is an environmental contaminant mainly present in fish and seafood. The long-term consumption of these fish and seafoods could pose a health risk to pregnant women and their children. Animal studies were conducted to assess the effects of MeHg exposure on reproduction and offspring development as well as the potential benefits of nutrient supplementation. Adult female rats were treated by gavage with MeHg at dose levels of 0.5, 1.0 or 2.0 mg/kg/day for 4 weeks prior to mating and throughout pregnancy, and then were allowed to deliver. In a second study, adult female rats were treated with MeHg at 1.25 mg/kg/day for the same duration, and they were fed diets containing an extra 1 ppm selenium (Se), or 225 IU/kg vitamin E, or both of these two nutrients, 4 weeks prior to MeHg dosing, and then throughout McHg treatment.

Abstract:
<p> Alzheimer&rsquo;s disease (AD) is the most common irreversible form of dementia and accounts for 60&ndash;80% of all dementia cases. It is not a normal part of aging and causes memory problems and other cognitive dysfunctions that may result in unpredictable changes in behavior. AD can be caused by many factors. Recently, Vitamin D deficiency has been recognized as a risk factor for AD. Vitamin D insufficiency and deficiency are major health problems affecting 1 billion people worldwide, across all ethnicities and age groups. Unfortunately, public knowledge about Vitamin D deficiency and risk of AD is limited. The creation of two leaflets as informational tools for experts/professionals and families/caregivers/participants of Alzheimer&rsquo;s Orange County was the goal of this project. The leaflets were reviewed by experts in the field and revisions were made. Future research should evaluate the effectiveness of the leaflets on increasing knowledge about Vitamin D and AD.</p><p>

Abstract:
The ageing population is predicted to exceed two billion by 2050; maintaining good health in older age has, thus, become a major global health priority. Ageing involves physiological changes, impairment in digestive function and the increased need for the use of prescribed drugs which can lead to lower status of folate and the metabolically related B-vitamins (vitamins B I2, B6, riboflavin). Deficiencies in these vitamins are increasingly linked with a number of chronic diseases of ageing. In particular, dementia affects 46.8 million globally, figures that are expected to triple by 2050, generating substantial societal and economic impacts. One-carbon metabolism is proposed as a critical pathway associated with health throughout life, especially in ageing. However, studies considering the association of one-carbon metabolism tend to focus on folate and vitamin B 12, few have considered all the relevant B-vitamins which are interlinked within one-carbon metabolism. The overall aim of this thesis therefore, was to investigate the causes, consequences and public health implications of low B-vitamin status in ageing with a particular focus on cognitive health. Results arising from new analysis of the Trinity, Ulster and Department of Agriculture (TUDA) Ageing cohort study (n 5186) indicated that the use of proton pump inhibitors (PPI), widely taken by older people, is associated with significantly lower status of B12 as previously reported, but also with lower status of vitamin B6 and riboflavin, vitamins which have not previously been linked with PPI use. Likewise, metformin use was associated with a significant increase in the risk of vitamin B12 deficiency and more than doubled the risk of vitamin B6 deficiency, in older people with or at-risk of diabetes (HbAic<42mmol/mol). The thesis showed that older adults with or at-risk of diabetes were at a 25% higher risk of vitamin B6 deficiency, and a 67% increased risk of cognitive dysfunction, with some evidence that low status of vitamin B6 may be driving the cognitive dysfunction in these patients. In a follow up study of almost 600 participants, 5 years after the initial investigation (i.e. TUDA+5), low status of vitamin B6 (OR: 1.75, P 0.008) and riboflavin (OR 1.63, P 0.018) were found to be significant predictors of accelerated cognitive decline, as measured by RBANS. The totality of the evidence in this thesis supports the wider public health benefits of optimising B-vitamin status, through natural food sources, fortified foods and supplements, to alleviate B-vitamin depletion in those on long term prescribed drugs and as a means of maintaining cognitive health in ageing. In conclusion, results from this thesis suggest that updating food fortification policies worldwide to optimise all the relevant B-vitamins could offer a cost-effective strategy for maintaining better health in ageing and preventing adverse outcomes.

Abstract:
Vitamin D deficiency is considered to be a pandemic with implications for compromised bone health and other chronic diseases. Few studies have examined vitamin D status in college-aged individuals where prevention of future health consequences is still possible. Serum vitamin D 25(OH)D status and vitamin D intake were examined in 98 college students ages 18-29 years during winter. BMI was classified as < 25and 25 or greater. Race was categorized as Caucasian or other. Overall, 69.5% had suboptimal serum vitamin D levels, <30ng/mL. Only 8 students (8.2%) met the EAR (400 IU) per day for vitamin D intake. t tests were used to determine if there were significant differences in serum vitamin D level and dietary intake based on gender, race and BMI. Significant differences were found in serum vitamin D level when compared by gender and race. Females tended to have a higher serum vitamin D level than males. Those representing minorities had lower serum vitamin D levels than Caucasians; One hundred percent of the minority students had suboptimal serum vitamin D levels. Based on these findings, dietitians should increase efforts to target college-aged individuals in educational programming related to factors affecting vitamin D synthesis, vitamin D intake, and health consequences of suboptimal vitamin D status, particularly in winter. Consideration should be given to vitamin D fortification of foods that meet the preferences of today’s consumer.

Abstract:
Objectives. To estimate calcium and vitamin D intakes in Canadian men and women, to compare these intakes to Canadian guidelines, and to determine factors associated with intake of these nutrients.<br>Methods. We estimated intakes of calcium and vitamin D from both diet and supplements using cross-sectional data from 9,423 randomly selected subjects 25 years of age and older who completed an interviewer administered abbreviated food frequency questionnaire. The participants were recruited from July 1995 to September 1997 in nine centres across Canada. We characterized the relationships of calcium and vitamin D with socio-demographic and lifestyle variables, physical characteristics, medical diagnosis and use of osteoporosis related medications.<br>Results. The median daily intake for calcium was estimated to be 930 (interquartile range (IQR) = 589;1360) mg for women, and 774 (IQR = 507;1155) mg for men; for vitamin D, intakes were 3.6 (IQR = 1.1;10.0) pg and 2.7 (IQR = 0.9;7.5) pg for women and men, respectively. Age and study centre were found to be associated with calcium and vitamin D intakes in both genders. Other variables associated with calcium intake included vitamin D intake, weekly energy expenditure and femoral neck bone mineral density. Factors found to be associated with vitamin D intake in both genders included calcium intake, height and caffeine intake.<br>Conclusions. The only group that on average met adequate daily intake levels for calcium was women aged 51-70. For vitamin D, on average, women and men under age 51 met adequate intake levels. Further education programs may be required to encourage increased consumption of these nutrients.

Abstract:
Over the past several decades, there has been a sharp increase in psychiatric diseases but relatively little attention to improving poor nutritional patterns that affect mental health conditions. Long-term nutrient deprivation results in neuroinflammation, which contributes to causing mental illnesses such as depression, anxiety disorder, and schizophrenia. A growing body of research substantiates the benefits of supplementing many essential nutrients such as omega-3 fatty acids, vitamin D, the B complex vitamins, vitamin E, and the minerals magnesium, iron, zinc, choline, calcium, and selenium to help prevent and treat many mental illnesses. These nutrients are often limited in the standard Western diet. Importantly, it is not just one single nutrient that is important to optimizing brain health but all the nutrients working in concert in a healthy, well-balanced approach that helps to optimize brain function and prevent disease. This chapter reviews the various nutrients involved in maintaining optimal brain health.

Abstract:
AbstractAchieving and maintaining skeletal health throughout the life trajectory is essential for the prevention of bone diseases such as rickets, osteomalacia and osteoporosis. Rickets and osteomalacia are usually a result of calcium and/or vitamin D deficiency, causing softening of bones and bone pain, and both conditions are treatable with calcium and vitamin D supplementation. Osteoporosis is a multifaceted disease mainly affecting older people, and its pathogenesis (and hence treatment) is more complex. Untreated osteoporosis results in fragility fractures causing morbidity and increased mortality.Nutrition is one of many factors that influence bone mass and risk of bone disease. Developing a nutritional sciences approach is a feasible option for improving bone health.The importance of adequate calcium and vitamin D in ensuring skeletal integrity throughout the life course has a sound evidence base. Poor vitamin D status in population groups of all ages is widespread across many countries (including affluent and non-affluent areas). Public health approaches are required to correct this given the fact that vitamin D is not just required for musculoskeletal health but also for other health outcomes.Dietary protein may be beneficial for bone due to its effect of increasing insulin-like growth-factor-1 (IGF-1). Recent meta-analyses show that dietary protein has a beneficial role to play in bone health at all ages.Other nutritional factors and nutrients (such as potassium, magnesium, vitamin K and acid-base balance) are also likely to have an important role in bone health, though the literature is less clear in terms of the association/relationship and more research is required.

Abstract:
ABSTRACT Background: The leading cause of mortality in children under five years of age is acute lower respiratory tract infections, especially bronchiolitis and pneumonia. Vitamin A supplement has been studied as a potential intervention to decrease severity and prevent acute lower respiratory tract infections from subsequent episodes. This study aimed to determine the relationship between vitamin A deficiency and pneumonia incidence of children under five years of age in West Java. Subjects and Method: A cross-sectional study was conducted using the secondary data from Indonesian Demographic and Health Survey, 2017 in West Java. A sample of 594 toddlers under 5 years of age was obtained for this study. The dependent variable was pneumonia. The independent variable was vitamin A intake. The data were collected using questionnaires. The data were analyzed by chi-square. Results: As many as 38.6% children under five years of age did not get vitamin A supplement. 26.8% of children suffered pneumonia. Inadequate vitamin A intake increased the risk of pneumonia in children under five years of age (OR= 1.011, 95% CI 0.690 to 1.481; p= 1.000). Conclusion: Inadequate vitamin A intake increases the risk of pneumonia in children under five years of age, but it is not statistically significant.
