Vitamin K - content in food and dietary intake among the Danes

Insufficient information on the content of vitamin K2 in our foods hinder estimation of the dietary intake. We aimed to establish content of eight vitamin K vitamers, vitamin K1 (phylloquinone; PK) and vitamin K2 (menaquinones; MK-4 to MK-10) in 88 composite food samples representing dairy, eggs, meat, fish, cereals, and plant-based alternatives to dairy. Combined with PK data for other foods, the dietary intake among Danes was estimated. The unit’PKeq’ is used to compensate for the difference in molecular weight for MK-4 at 445 g/mol up to MK-10 at 853 g/mol. The highest content was found in chicken thigh with skin at 53 μg PKeq/100 g followed by 49 μg PKeq/100 g in Danablue (blue cheese). The daily intake of vitamin K is 139 μg to 160 μg PKeq for adults. The highest percentage comes from PK (64 %), 27 % from MK-4, 4.6 % from MK-9, and 2.4 % from MK-8.

Adherence to Essential Nutritional and Lifestyle Practices among the Residents of Urban and Rural Settings during COVID-19 at Jashore District in Bangladesh

Background: High population density makes Bangladesh more vulnerable to a pandemic situation like COVID-19. It is evident from the scientific literature that proper nutritional practices might be effective in preventing various infections. The objective of this research work was to explore the nutritional as well as lifestyle practices among the urban-rural residents of Jashore district and to assess the association of those practices with their residential settings. Methods: It was a cross-sectional study where about 134 respondents (18-50 years) were selected by convenience sampling method from eight rural and seven urban areas of Jashore district in Bangladesh. Association between residence type and various concerned practices have been explored by Pearson chi-square test, binary and multinomial logistic regression analysis. Results: It was found from the results of binary and multinomial logistic regression that, the intake of vitamin D rich foods (OR: 3.45; 95% CI: 1.48,8.07), folic acid rich foods (OR:0.20; 95% CI:0.09,0.46), vitamin B12 rich foods (OR:0.11; 95% CI:0.02,0.52), iron rich foods (OR:0.23; 95% CI:0.08,0.66), and melatonin rich foods (OR:0.15; 95% CI:0.05,0.40) were significantly associated (P<.05) with residential area (urban and rural) of the respondents. On the other hand, no association was found (P>.05) between other immune-boosting nutrient-rich foods such as complex carbohydrates, polyunsaturated fatty acid, vitamin A, vitamin E, vitamin C, Pyridoxine, zinc and selenium rich foods and respondents’ residential area. Moroever, the association was not observed (P>.05) in case of supplement intake of various immune boosting nutrients and area. Among the lifestyle practices, no significant association was found regarding sleep patterns among the respondents but various daily physical movements (OR: 0.19; 95% CI:0.07,0.48) were found higher among the rural respondents. Conclusion: Daily intake of vitamin D rich foods was found higher among the urban respondents but daily intake of folic acid, vitamin B12, iron and melatonin rich foods were found higher among the rural residents. It was also observed that the physical activities were better maintained among the rural respondents than their urban counterparts. Bioresearch Commu. 10(2): 1545-1552, 2024 (July)

Vitamin D prophylaxis in persons with epilepsy?

Limited guidelines exist regarding osteoporosis prevention in the general population. Despite being a subject of controversy, the majority of research suggests that decreased vitamin D levels correlate with increased bone turnover, that is, an important risk factor for osteoporosis development. In most guidelines, daily vitamin D supplementation is recommended. In persons with epilepsy (PWE), the situation is more complex, as other factors can increase the chance of being vitamin D deficient. Currently, there are no internationally accepted guidelines regarding monitoring bone health in PWE. Our aim was to review the existing evidence in PWE on: (1) risk factors for vitamin D deficiency, (2) the identification of higher risk groups, and (3) the optimal ways to monitor bone health. Our narrative review shows that: (1) anti-seizure medication (ASM) use, especially enzyme-inducing ASM (EIASM) and valproic acid, is identified as an important risk factor for impaired bone health (e.g., increased risk for osteoporosis/fractures and/or vitamin D deficiency); (2) higher risk groups within the PWE population are present: intellectual or physical disability, institutionalized patients, puberty, early onset epilepsy and developmental epileptic encephalopathies, postmenopausal women, and use of multiple ASM/concomitant drugs (e.g. corticosteroids); and (3) a monitoring scheme can be suggested including laboratory tests, bone density measurements, managing of risk factors, and/or vitamin D supplementation. Overall, regular vitamin D measurement in PWE is a cost-effective and practical method for monitoring vitamin D deficiency, whereas in high-risk patients the combination of vitamin D measurement and bone densitometry is recommended. There is not enough evidence to advocate continuous vitamin D supplementation in all PWE. Children with epilepsy should receive the recommended daily intake of vitamin D for age and additional monitoring and supplementation if at higher risk of deficiency. There is a need for prospective trials exploring the potential benefit of vitamin D supplementation in PWE.

Nutritional Challenges in Nursing Homes: Pilot Study on Macronutrient Intake and Status of Vitamins D and B12.

Older adults living in nursing homes (NH) are considered a population group that could be at risk in terms of nutrition, even more so than their community-dwelling peers. Evidence on the nutritional status of NH residents is scarce, as they are commonly excluded from population-based dietary studies. This is also the case in Slovenia. In the presented pilot study, we assessed the intake of macronutrients as well as the intake and status of vitamin D and vitamin B12 on a sample of NH and NH daycare center users to explore the need for a larger representative study. The pilot study included 37 participants from three Slovenian NH (20 participants) and their daycare centers (17 participants). Daycare centers offer daytime care services for older adults, where users are also provided with major meals during their stay. Intakes of energy and nutrients were estimated by three 24 h dietary records. Fasting blood samples were collected for the assessment of vitamin D and vitamin B12 status. Over 90% of the participants had daily energy and protein intakes below recommendations (reference values: energy intake: males 2100 kcal and females 1700 kcal; protein intake > 1 g/kg body mass). The males' median daily intakes of vitamin D were 1.7 µg (1.5 µg females), and 2.3 µg for vitamin B12 (2.0 µg females). None of the participants had adequate vitamin D intake (>20 µg), and 92.3% males and 87.5% females had inadequate vitamin B12 intake (<4 µg). The prevalence of vitamin D deficiency (serum 25-OH-D conc. < 30 nmol/L) was 100% among NH residents and 53% among NH daycare center users. The prevalence of vitamin B12 deficiency was found in 20% of NH residents. The study results highlighted that certain nutrients might be critical in this population, especially among NH residents; however, a more thorough investigation with the inclusion of other important markers of nutritional status should be performed on a larger, representative sample to support the development and implementation of appropriate public health interventions.

Vitamins in Gynecologic Malignancies.

The combination of vitamin A and D derivatives with classical chemotherapeutic treatments results in more satisfactory outcomes. The use of drug combinations, such as 9cUAB130 with carboplatin and cisplatin with TAC-101, shows enhanced cytotoxic effects and reductions in ovarian tumor volume compared to single-drug treatments. Combining cisplatin with calcitriol and progesterone increases VDR expression, potentially enhancing the effectiveness of anticancer therapy in ovarian cancer. The effectiveness of vitamin derivatives in anticancer treatment may vary depending on the characteristics of the tumor and the cell line from which it originated. An increase in thiamine intake of one unit is associated with an 18% decrease in HPV infection. Higher intake of vitamin C by 50 mg/day is linked to a lower risk of cervical neoplasia. Beta-carotene, vitamin C, and vitamin E are associated with risk reductions of 12%, 15%, and 9% in endometrial cancer, respectively. A balanced daily intake of vitamins is important, as both deficiency and excess can influence cancer development. It has been observed that there is a U-shaped relationship between group B vitamins and metabolic markers and clinical outcomes.

Nutrient intake and risk of multimorbidity: a prospective cohort study of 25,389 women

BackgroundMultimorbidity is becoming an increasingly serious public health challenge in the aging population. The impact of nutrients on multimorbidity remains to be determined and was explored using data from a UK cohort study.MethodOur research analysis is mainly based on the data collected by the United Kingdom Women’s Cohort Study (UKWCS), which recruited 35,372 women aged 35–69 years at baseline (1995 to 1998), aiming to explore potential associations between diet and chronic diseases. Daily intakes of energy and nutrients were estimated using a validated 217-item food frequency questionnaire at recruitment. Multimorbidity was assessed using the Charlson comorbidity index (CCI) through electronic linkages to Hospital Episode Statistics up to March 2019. Cox’s proportional hazards models were used to estimate associations between daily intakes of nutrients and risk of multimorbidity. Those associations were also analyzed in multinomial logistic regression as a sensitivity analysis. In addition, a stratified analysis was conducted with age 60 as the cutoff point.ResultsAmong the 25,389 participants, 7,799 subjects (30.7%) were confirmed with multimorbidity over a median follow-up of 22 years. Compared with the lowest quintile, the highest quintile of daily intakes of energy and protein were associated with 8% and 12% increased risk of multimorbidity respectively (HR 1.08 (95% CI 1.01, 1.16), p-linearity = 0.022 for energy; 1.12 (1.04, 1.21), p-linearity = 0.003 for protein). Higher quintiles of daily intakes of vitamin C and iron had a slightly lowered risk of multimorbidity, compared to the lowest quintile. A significantly higher risk of multimorbidity was found to be linearly associated with higher intake quintiles of vitamin B12 and vitamin D (p-linearity = 0.001 and 0.002, respectively) in Cox models, which became insignificant in multinomial logistic regression. There was some evidence of effect modification by age in intakes of iron and vitamin B1 associated with the risk of multimorbidity (p-interaction = 0.006 and 0.025, respectively).ConclusionsOur findings highlight a link between nutrient intake and multimorbidity risk. However, there is uncertainty in our results, and more research is needed before definite conclusions can be reached.

Soybean Oil as a Green Solvent for the Recovery of Carotenoids from Banana Peel: Evaluation of the Storage and Processing on Final Product

This study aimed to recover carotenoids from banana peel by employing a solid-liquid extraction using soybean oil as a green solvent. The oil with the highest total carotenoid content was evaluated for storage stability (30 °C/90 days) and thermal processing (100 and 200 °C/1–2 h). The results for changing temperature (33–67 °C), solid-liquid ratio (1:6–1:74 w/w), and agitation (132–468 rpm) were combined to evaluate the recovery of carotenoids from banana peel in extractions performed for 1 h. The highest total carotenoid concentration obtained from banana peel with 13% residual moisture was 756 µg of β-carotene/mL of oil at 50 °C with a solid-liquid ratio of 1:6 and 300 rpm agitation, resulting in a 55% recovery, which is superior to the extraction using acetone as the solvent (50%). Nutritionally, the carotenoid-rich oil can substantially increase vitamin A intake since a 13-mL serving can correspond to 63–117% of the daily intake of vitamin A for different groups. Regarding storage, no differences were observed in the fatty acid profile of the carotenoid-rich oil and the control (pure soybean oil) after 90 days (p &gt; 0.05). The fatty acid profile also remained the same after thermal processing, regardless of temperature and exposure time, except for linolenic acid. 84% retention of total carotenoids was observed after storage. For thermal processing at 100 and 200 °C, regardless of the processing time, a 91 and 31% retention were observed, respectively. Therefore, the use of banana peel as a raw material to obtain carotenoids using soybean oil as a green solvent can add value to production chains, and it is aligned with Sustainable Development Goals 2 and 12 of the UN 2030 Agenda, which aims to end hunger, achieve food security, promote sustainable agriculture and ensure sustainable consumption and production patterns, respectively.

Bioactive compounds and antioxidant activity in three types of Korean watery kimchi

Watery kimchi is a traditional fermented food served with its soup. In this study, we collected 21 samples of yeolmu mul kimchi (YMK), dongchimi (DC), and nabak kimchi (NK), respectively, which are the most popular watery kimchi in Korea. A composite sample of each watery kimchi was prepared for estimation of their bioactive compounds and antioxidant activities. Of the three kimchi types, YMK had the highest total carotenoid content (63.78 ± 4.88 mg/100 g, of which lutein, capsanthin, and β-carotene were the main carotenoids), and DC had the lowest (3.50 ± 0.12 mg/100 g). YMK also had the highest contents of chlorophyll (250.1 ± 3.91 mg/100 g), ascorbic acid (447.16 ± 8.95 mg/100 g), and capsaicinoids (2.51 ± 0.09 mg/100 g) compared to DC and NK. The lactic acid content was highest in NK (582.72 ± 29.10 mg/100 g). Moreover, YMK showed significantly higher antioxidant activity (ABTS and DPPH) than DC and NK (p < 0.05). Chlorophyll and antioxidant activity showed a strong positive correlation (p < 0.01). The results of this study highlighted watery kimchi as a potentially valuable source of bioactive compounds, and the carotenoids and capsaicinoids were affected by the supporting ingredients used in watery kimchi. Furthermore, watery kimchi provides 4.11% of the recommended daily intake of vitamin A according to the 2020 Korean dietary reference intakes.

Association between vitamin D status, physical performance, sex, and lifestyle factors: a cross-sectional study of community-dwelling Kosovar adults aged 40years and older.

Vitamin D status and its association with age-related decline in physical performance and strength have already been highlighted in various ways, but data on the situation in developing countries are scarce. This study aimed to investigate vitamin D status, its association with muscle mass and function, and other potential determinants such as age, sex, lifestyle factors (physical activity, dietary behavior), self-perceived health status, medication intake, education and financial situation in adults from Kosovo. This cross-sectional study included 297 participants (54.5% women), aged ≥ 40years. Serum 25-hydroxyvitamin D (25(OH)D) concentration, hand grip strength and physical performance tests, body composition, vitamin D dietary intake and knowledge were assessed. The interaction between serum 25(OH)D status, lifestyle factors and muscle traits was investigated. Vitamin D deficiency (< 50nmol/L) was observed in 47.5% of the total population, of whom 14.7% of them were severely deficient (< 30nmol/L). No associations were found between 25(OH)D concentration and age. Daily dietary intake ofvitamin D was low (1.89 ± 0.67µg) and 87.6% of individuals did not take vitamin D supplements. However, vitamin D supplementation was the only variable that added statistical significance (p < 0.05) to the prediction of vitamin D status (3.8%). On the other hand, age, medication intake and vitamin D level contributed significantly to the overall regression model, explaining 24.9% of the 30-s chairstand performance as an indicator of lower-body strength endurance. Vitamin D deficiency is highly prevalent among community-dwelling adults in Kosovo and low serum 25(OH)D has been associated with low muscle strength. This implies an urgent need for the development of comprehensive prevention strategies, focusing on pharmacological (supplementation) but alsoon non-pharmacological strategies such as education, foodfortification or lifestyle advices.

Mental Health Component Scale Is Positively Associated with Riboflavin Intake in People with Central Obesity.

Micronutrient deficiencies are a well-established fact in obesity. However, few studies exist on the relationship between micronutrient intake and mental health. In this study, we investigated the associations between daily intakes of vitamins and minerals and scoring items that measure mental health in people living with central obesity. One hundred males and females with central obesity and metabolic abnormalities were included in the study. Demographic, clinical, anthropometric, and biochemical data were collected. Mental health statuses were assessed with validated questionnaires, and daily micronutrient intakes were assessed with food diaries and Nutritionist ProTM software v7.9. The mental component score (MCS-12) positively correlated with vitamin A (Rho = 0.249, p = 0.038), vitamin C (Rho = 0.293, p = 0.014), riboflavin (Rho = 0.264, p = 0.026), and folate (Rho = 0.238, p = 0.046). Rosenberg Self-Esteem Scale (RSES) correlated with sodium (Rho = 0.269, p = 0.026), and the Center for Epidemiologic Studies Depression Scale Revised (CESD-R) correlated with chromium (Rho = 0.313, p = 0.009). In the regression analysis, after potential confounders were adjusted for, only riboflavin was positively associated with the MCS-12 log (beta ± SD = 0.047 ± 0.023, p = 0.044). Our study provides evidence of the link between dietary riboflavin and mental health in people with obesity, and it highlights the importance of monitoring both nutritional status and mental health when managing obesity.

Composite Dietary Antioxidant Index Is Negatively Associated with Hyperuricemia in US Adults: An Analysis of NHANES 2007-2018.

Hyperuricemia and its complications are severe risks to human health. Dietary intervention is considered an essential part of the management of hyperuricemia. Studies have reported that the intake of antioxidants has a positive effect on hyperuricemia. Here, we collected data from 8761 participants of the National Health and Nutrition Examination Survey for this analysis. Daily intakes of vitamins A, C, and E; manganese; selenium; and zinc were calculated as the composite dietary antioxidant index (CDAI). The participants were divided into four groups (Q1, Q2, Q3, and Q4) according to the CDAI. Univariate analysis was used to assess the association of covariates with hyperuricemia. The association between the CDAI and hyperuricemia was evaluated using multinomial logistic regression, and its stability was determined by stratified analysis. Our results revealed that the CDAI has a significant negative association with hyperuricemia (Q2: 0.81 (0.69, 0.95); Q3: 0.75 (0.62, 0.90); Q4: 0.65 (0.51, 0.82); P < 0.01). The results of stratified analysis emphasize that this association between CDAI and hyperuricemia is stable. In conclusion, this study suggested a negative association between the CDAI and hyperuricemia.

Processing overwhelms biostimulant‐induced vitamin E improvement in lentils

AbstractAlthough biostimulants are used in crop cultivation to improve productivity and/or quality of fruit and vegetables, their effect is rarely investigated up to processed food. Here, we investigated whether vitamin E content in lentils can be influenced by caffeine used as a biostimulant in a greenhouse‐controlled experiment, and how cooking influences its intake in our diet. Results showed that contents of γ‐tocopherol, the most abundant vitamin E homologue, increased by 27% upon biostimulant application during cultivation in raw lentils. However, these positive effects were completely abolished in the processed food, so cultivation differences had no effect on the cooked lentils. Cooking reduced by 43% and 50% of the contents of α‐ and γ‐tocopherols, respectively. A comparative study of vitamin E contents revealed that our lentil variety (variety ‘Pardina’ from ecological origin) contained more vitamin E than any other variety described thus far, with α‐ and γ‐tocopherol contents of 0.86 and 6.83 mg/100 g FW in raw lentils, and 0.49 and 3.42 mg/100 g FW in cooked lentils, respectively. A bowl of cooked ‘Pardina’ lentils, which are very typical in Mediterranean and Middle Eastern diets, can therefore represent a substantial proportion of the daily intake of vitamin E.

Ultraviolet-B radiation, mushrooms, and vitamin D: From technology to bioavailability

We describe an efficient technology to obtain vitamin D2-enriched mushroom powder by exposing postharvest shiitake mushrooms (Lentinula edodes) to UV-B radiation. UV-B exposure took place in a self-designed semi-industrial facility with the required safety measures. The highest vitamin D2 content (1000 IU g−1 DM) was found when a total UV-B dose of 24 kJ m−2 was distributed in two different moments of the process (75% on sliced fresh mushroom and the remaining 25% on the dry powder). Similar results were obtained in king oyster (Pleurotus eryngii) and Portobello button (Agaricus brunnescens) mushrooms, indicating that the developed technology could generally be used to produce vitamin D2 supplements from mushrooms. In addition, the same method increased the vitamin D2 content in shiitake by-products, which could be used for animal feed. The microbiological, toxicological, and nutritional quality of the enriched mushroom preparations were confirmed to ensure a safe consumption. To determine the vitamin D bioavailability in humans, the enriched shiitake powder was encapsulated using 600 mg per capsule, which was equivalent to the minimum daily intake of vitamin D for adults. The capsules were ineffective in improving serum 25-hydroxyvitamin D status, but prevented an excessive decrease in this parameter due to winter conditions.

Dietary vitamin D intake and the bladder cancer risk: A pooled analysis of prospective cohort studies

Diet may play an essential role in the aetiology of bladder cancer (BC). Vitamin D is involved in various biological functions which have the potential to prevent BC development. Besides, vitamin D also influences the uptake of calcium and phosphorus, thereby possibly indirectly influencing the risk of BC. The aim of the present study was to investigate the relation between vitamin D intake and BC risk. Individual dietary data were pooled from ten cohort studies. Food item intake was converted to daily intakes of vitamin D, calcium and phosphorus. Pooled multivariate hazard ratios (HRs), with corresponding 95% confidence intervals (CIs) were obtained using Cox-regression models. Analyses were adjusted for gender, age and smoking status (Model 1), and additionally for the food groups fruit, vegetables and meat (Model 2). Dose-response relationships (Model 1) were examined using a nonparametric test for trend. In total, 1994 cases and 518,002 non-cases were included in the analyses. The present study showed no significant associations between individual nutrient intake and BC risk. A significant decreased BC risk was observed for high vitamin D intake with moderate calcium and low phosphorus intake (Model 2: HRhigh vitD, mod Ca, low P: 0.77, 95% CI: 0.59-1.00). No significant dose-response analyses were observed. The present study showed a decreased BC risk for high dietary vitamin D intake in combination with low calcium intake and moderate phosphorus intake. The study highlights the importance of examining the effect of a nutrient in combination with complementary nutrients for risk assessment. Future research should focus on nutrients in a wider context and in nutritional patterns.

GAMBARAN KADAR VITAMIN C PADA MINUMAN SARI LEMON (Citrus Limon) DENGAN METODE SPEKTROFOTOMETRI UV – Vis DI KOTA SAMARINDA

Lemon (Citrus limon L.) is more popular in the culinary industry because it has a fresh citrus aroma and parts used with juice. Some of the benefits of lemon can be used as a garnish for food and drinks. One example of a drink made from lemons is lemon juice. The level of vitamin C that the body needs is only around 90 mg, while one lemon (Citrus limon L.) contains 60-100 mg of vitamin C, so one lemon (Citrus limon L.) can meet the body's vitamin C needs (Kristanto, 2013). The purpose of this study was to describe the levels of vitamin C in lemon juice (Citrus limon L.) using UV-Vis spectrophotometry method in Samarinda City. The type of research conducted was descriptive research with random sampling technique. In this study there were 20 samples taken from different traders. The maximum wavelength in the study was 265 nm. The linear regression equation obtained is y=0,0621001x + 0,0132047. The lowest vitamin C levels were found in sample G, which was 18.30 mg/ml and samples with the highest levels of vitamin C were found in sample Q, which was 98.00 mg/ml. There is only 1 (5%) sample that meets the daily intake of vitamin C, namely the Q code sample.

The potential of non-traditional walnut shells waste for the production of antioxidant reach extracts intended for the food industry

Phenolic compounds extracted from walnut shells are potentially good natural sources of antioxidants for the food industry and have numerous health benefits. Walnuts have more antioxidant capacity than any other nut because the shell is primarily composed of lignin, a strong source of phenols. Studies demonstrated that lignin characterizes the shell strength level and is a source of antioxidants due to its chemical composition. In the current study, an extract obtained by extraction with a hydroalcoholic solvent of various concentrations from a walnut shell was investigated. The results of this study have proven that walnut shell extract contains the main sources of mineral elements and vitamins, which are of great importance. According to the biological value, this extract contains essential amino acids for the body. The high content of quercetin and catechin shows the antioxidant activity of the extract. In the present article, the authors disclose methods for obtaining an experimental batch of a prophylactic product based on walnut shells and give the product a technological characteristic. Consequently, a product was developed for prophylactic usage of 10 ml per 100 ml of water and must be taken 1-2 times a day for 21 days. The required product amount was calculated from the daily intake of vitamins, minerals, and flavonoids.

Understanding the Molecular Aspects of Vitamins in Parkinson's Disease: Present-day Concepts and Perspectives.

Parkinson's disease (PD) is designated as a convoluted nerve cell devastating disorder that encompasses the profound declination of dopaminergic (DArgic) nerve cells of the mesencephalon region. The condition is sketched by four eminent motor manifestations, namely, slow movement, muscle tension, shaking, and disrupted balance, but the pathology behind these manifestations is still vague. Modern-day medicinal treatment emphasizes curbing the manifestations via introducing a gold standard (levodopa) instead of forestalling the DArgic nerve cell destruction. Therefore, the invention and utilization of novel neuroprotective candidates are of paramount importance in overcoming PD. Vitamins are organic molecules engaged in the modulation of evolution, procreation, biotransformation, and other operations of the body. Numerous studies employing varying experimental models have promulgated a prominent linkage between vitamins and PD. Vitamins, owing to their antioxidant and gene expression modulation abilities, might be efficacious in PD therapy. Recent corroborations depict that adequate augmentation of vitamins might de-escalate the manifestations and emergence of PD; however, the safety of daily vitamin intake must be considered. By assembling the comprehensive information obtained from existing publications via searching various renowned medical portals, the investigators render in-depth insights into the physiological association amongst vitamins (D, E, B3, and C) and PD and concerned pathological processes and their safeguarding actions in varied PD models. Furthermore, the manuscript delineates the remedial aptitude of vitamins in PD therapy. Conclusively, augmentation of vitamins (owing to their antioxidant and gene expression regulation capabilities) might appear as a novel and terribly efficacious ancillary therapeutic approach for PD.

Vitamin content in the diet among 14- to 15-year-old teenagers depending on the BMI value.

In a period of intensive growth and development, both a deficiency and an excess of nutrients may have negative consequences on health. In the case of vitamins, an ongoing deficiency can result which have a direct effect on public health. The research included all third-year middle school pupils. With the assistance of the person conducting the research, a questionnaire was completed about consumption of food products consumed every day for a period of 7 days. Energy and nutrient requirements were defined individually for each child in terms of RDA. The daily intake of group B vitamins was exceeded both in the boys' group and the girls' group. The daily intake of vitamin C and folates was higher in the boys' group than in the girls' group, but did not meet the required daily intake in any of the groups studied. In all boys' groups, the intake of vitamin D covered less than 30% of the required daily amount. It has been shown that there is a statistically significant influence of the intake of vitamins on body mass. In the girls' group, the most common statistically significant differences were between the group of underweight girls and the groups of girls with correct body weight and overweight girls. Insufficient intake of vitamins is observed most often in underweight adolescents. The incorrect amount of vitamins in the diet requires the implementation of action to improve the dietary preferences of adolescents.

Intake and Contribution of Food Groups to Vitamin D Intake in Adults with Overweight and Obesity

The aim of the present study is to investigate the dietary intake of vitamin D in normal-weight and overweight individuals, establishing its correlation with specific food groups.&#x0D; Two hundred and sixty-four individuals were studied, of which 41.3% men and 58.9% women between 19 and 60 years of age. Nutritional assessment was carried out applying 24-h recall in the months January to April in 2014 and 2015. Nutritional status was assessed by means of anthropometric indicators – anthropometric indicators and indices, whereas weight and body composition were measured by professional bioelectrical impedance using a Tanita 420 BC MA device.&#x0D; It was established that the average daily intake of vitamin D for the entire group of studied individuals was 6.6 µg/day (women – 5.6 µg/day and men – 10.4 µg/day). Main dietary sources of vitamin D in the diet of adults were meat and meat products, fish and fish products, eggs and milk and dairy products. In the groups based upon BMI category of participants, meat and meat products were found to be the main source of vitamin D in all groups.&#x0D; Average daily intake of vitamin D has values significantly below the recommended average daily intake. A policy to promote the consumption of foods rich in vitamin D in order to reduce the relative share of individuals not meeting the recommendations is required.

Correlation between Dietary Intake of Vitamins and Oral Health Behaviors: A Cross-Sectional Study.

This study aimed to investigate whether oral health behaviors were related to the dietary intake of vitamins. In this cross-sectional study, we included respondents of the 2016 national health and nutrition examination survey, and dental diseases from Hyogo Prefecture, Japan. Data on sociodemographic characteristics, findings of blood tests related to metabolic syndrome, dietary intake, oral health status, and behaviors were collected. Participants were divided into two groups based on their oral health behavior: the yes group (performed interdental cleaning or tongue brushing) and the no group (did not perform the behaviors). The study included 218 participants (male: 107, female: 111) aged 64.5 (range, 22-93) years. There were 133 (61.0%) and 85 (39.0%) participants in the yes and no groups, respectively. The daily intake of vitamins A, B2, B6, E, and K, folic acid, and niacin in the yes group was significantly higher than that in the no group. Oral health behavior correlated with the intake of vitamin B2 (p = 0.029), folic acid (p = 0.006), and vitamin K (p = 0.043) after adjusting for possible confounders. Oral health behavior (interdental cleaning or tongue brushing) correlated with the daily intake of vitamins B2, K, and folic acid.
