Low Intake Of Vitamin Research Articles

Vitamin D, Folate, Vitamin B12, and Iron Status in Pregnant/Postpartum Old Order Anabaptist Women in Southwestern Ontario.

Purpose: To assess vitamin D, folate, vitamin B12, and iron status in Old Order Anabaptist (OOA) pregnant/postpartum women.Methods: Blood was analyzed for plasma 25 hydroxy vitamin D (25(OH)D), red blood cell (RBC) folate, serum vitamin B12, and iron status indicators. Dietary intakes (food and supplements) from 3-day estimated records were compared to Dietary Reference Intakes and Canada's Food Guide (2007).Results: Fifty women participated in this descriptive cross-sectional study. Concentrations of 25(OH)D were low (<50 nmol/L for 20% and < 75 nmol/L for 63%); 42% had total vitamin D intakes < estimated average requirement (EAR). All women had RBC folate above the 1360 mmol/L cut-off. Nineteen percent had folate intakes <EAR; 80% had folic acid supplement intakes >upper limit. One woman had low serum vitamin B12 (<148 pmol/L); serum vitamin B12 was high (>652 pmol/L) for 24%. None had vitamin B12 intakes <EAR; intakes were high compared to the recommended dietary intake. One woman had low hemoglobin; 13% had ferritin <15 μg/L. Thirteen percent had total iron intake <EAR.Conclusions: Overall, dietary intake and serum micronutrient status of OOA pregnant and postpartum women in our study were similar to those reported in previous studies of Canadian women. While some women had low intakes of vitamin D and iron, most had high intakes of folate and vitamin B12. These findings provide guidance to ensure appropriate dietary and supplement intakes in this potentially vulnerable and rarely studied population.

The Protective Role Antioxidant of Vitamin C in the Prevention of oral Disease: A Scoping Review of Current Literature.

This review meticulously examined the connection between vitamin C and periodontal disease, as well as the potential of vitamin C to prevent this condition. To gather relevant data, comprehensive electronic searches were conducted across various databases, including PubMed, EMBASE, Cochrane Library, and Web of Science, focusing on studies that explored the relationship between vitamin C and periodontal disease in individuals aged between 18 and above. From an initial pool of 421 articles, 14 were ultimately chosen for detailed analysis. This selection encompassed seven cross-sectional studies, two case-control studies, two cohort studies, and three randomized controlled trials. The analysis of these studies revealed a consistent negative association between vitamin C intake, as well as its levels in the blood, and the incidence of periodontal disease across all seven cross-sectional studies. This indicates that higher vitamin C intake and blood levels are linked to a decreased risk of developing periodontal disease. In the two case-control studies, individuals suffering from periodontitis were found to have both a lower intake of vitamin C and reduced levels of vitamin C in their blood compared to those without the disease, further underscoring the potential protective role of vitamin C against periodontal disease. The progression of periodontal disease was observed to be more rapid in patients with lower dietary intake or blood levels of vitamin C compared to controls. Regarding the effects of vitamin C administration as an intervention, there was an improvement noted in gingival bleeding among patients with gingivitis; however, no significant benefits were observed in cases of periodontitis, specifically concerning alveolar bone absorption. Through the meticulous examination of available studies, this systematic review underscores the notion that adequate vitamin C intake and maintaining sufficient levels of vitamin C in the blood can contribute significantly to reducing the risk of periodontal disease.

Effect of Vitamin C, D3, Ca Supplements and Olive Paste Enriched with Mountain Tea on Health Biomarkers in Postmenopausal Women with Osteopenia or Osteoporosis: A Prospective Interventional Study

Low dietary intake of calcium, vitamin D, vitamin C and magnesium has been associated with increased risk of osteoporosis. The purpose of the study was to evaluate changes in several bone health indicators and metabolic biomarkers in postmenopausal women with high osteopenia or osteoporosis, followed by a nutritional intervention program. In total, 115 apparently healthy postmenopausal women (52 ± 8 years old) were randomized into four groups: group I (n = 40) received daily 1000 mg vitamin C, 100 mcg vitamin D3, 500 mg calcium(Ca) and 300 mg magnesium (Mg); group II (n = 42) received daily 100 mcg vitamin D3, 500 mg Ca and 300 mg Mg; group III (n = 18) received daily 5 mg bisphosphonates, 100 mcg vitamin D3, 500 mg Ca and 300 mg Mg; and group IV (n = 15) received daily about 364 mg polyphenols via an innovative functional food (50 g olive paste enriched with mountain tea extract) along with 100 mcg vitamin D3, 500 mg Ca and 300 mg Mg. Groups I–III received supplementation for a year whereas group IV received supplementation for 5 months. Changes in bone health indicators and metabolic biomarkers were assessed at the beginning and at the end of the study. Anthropometric indices and whole-body bone mineral density (BMD) were also evaluated at the beginning and at the end of the intervention period. The results revealed improved elevated levels of 25(OH)D3 in groups II, III and IV (+3.71% and +1.45% and +5.62%, respectively). Significant positive changes were recorded for whole-body BMD in all four study groups. Significant beneficial changes for total cholesterol were observed in group IV (−2.07%, p &lt; 0.05) and positive changes in group I for HDL biomarkers (+61.62%, p &lt; 0.05). Additional larger-scale clinical trials and intervention studies are considered essential to fully investigate and elucidate associations between dietary components and biochemical indices of bone health.

Micronutrient Patterns and Low Intake of Vitamin A, Vitamin D, Folate, Magnesium, and Potassium Among Prediabetes and Type 2 Diabetes Patients.

Background Assessing micronutrient intake is important in identifying deficiencies that may contribute to insulin resistance, poor glycemic control, and increased risk of diabetes-related complications. The study's objectives were to evaluate micronutrient intake in prediabetes (PD) and type 2 diabetes (T2DM) patients compared to recommended dietary intakes (RDI) and to determine the associations between the micronutrient patterns and both anthropometric measurements and biomarkers of diabetes. Methods This cross-sectional study was conducted on 349 patients with T2DM and 252 patients with PD. Micronutrient intake was evaluated using a validated food frequency questionnaire. Micronutrient patterns were extracted from factor analysis using principal component analysis with varimax rotation. Participants in the highest tertile were considered to have the highest adherence to the corresponding micronutrient pattern. Results T2DM patients had a significantly lower intake of vitamin E (9.4 ± 0.2 vs. 10.1 ± 0.3 mg; p = 0.048), vitamin D (44.3 ± 1.1 vs. 48.9 ± 1.7 IU; p = 0.020), and thiamin (1.3 ± 0.1 vs. 1.4 ± 0.1 mg; p = 0.013) compared to PD patients. All patients had a significantly lower intake of vitamin A, vitamin D, folate, magnesium, and potassium and a significantly higher intake of vitamin B12 and copper compared to RDI. Three distinct micronutrient patterns were identified within each group. In the PD group, the Fe-Mn-Se pattern correlated significantly with waist circumference (WC) and fasting plasma glucose (FPG). The Vit.C-K-Folate pattern showed significant associations with body fat (BF). The Vit.B2-P-Vit.B12 pattern was significantly linked to WC, body mass index (BMI), BF, FPG, and serum insulin (SI). For the T2DM patients, the K-Folate-Mg pattern displayed an inverse and significant association with weight and WC. The Iron-Se-Vit.B3 pattern showed a significant association with low-density lipoprotein (LDL) cholesterol, triglycerides, and total cholesterol. The Vit.B2-P-Ca pattern was significantly associated with fasting plasma glucose (FPG). Conclusion This study demonstrated that T2DM patients had significantly lower vitamin E, vitamin D, and thiaminintake than PD patients. Both T2DM and PD patients had a significantly lower intake of vitamin A, vitamin D, folate, magnesium, and potassium compared to the RDI. Among the identified micronutrient patterns, only the K-Folate-Mg pattern exhibited a significant association withreduced body weight and WC.

Dietary intake and food sources of calcium and vitamin D in young children in the Guelph Family Health Study

Canadian research on dietary intake of calcium and vitamin D in young children is limited. This cross-sectional analysis investigated dietary intake and food sources of calcium and vitamin D among 265 preschool-aged children (3.6 ± 1.2 years) in the Guelph Family Health Study via one 24-h dietary recall completed by their parents using the Automated Self-Administered 24-H Dietary Assessment Tool 2016-Canadian version. Median intakes of calcium and vitamin D were 827 mg d−1 [Interquartile range (IQR) = 522] and 4.0 μg d−1 (IQR = 3.6), respectively. The two most frequently consumed dairy food sources for both nutrients were fluid cow's milk (78%, n = 206) and cheese (60%, n = 160), whereas the most frequently consumed non-dairy food sources for calcium were fruits (92%, n = 243), bakery products (92%, n = 243), and water (92%, n = 243), and for vitamin D it was bakery products (74%, n = 196). Findings raise concern about low intakes of calcium and vitamin D in young Canadian children.

Dietary Intakes of Women with Gestational Diabetes Mellitus and Pregnancy Outcomes: A Prospective Observational Study.

Nutrient intake for pregnant women with gestational diabetes mellitus (GDM) is important to ensure satisfactory birth outcomes. This study aims to explore the dietary profiles of patients with GDM, compare the results with the Chinese dietary guidelines or Dietary Reference Intakes (DRIs) from China and investigate the relationship between maternal dietary intake and pregnancy outcomes. A total of 221 patients with GDM in the second trimester were included in the cohort. Dietary intake data were collected using a 24-hour recall method for three consecutive days. The pregnancy outcomes of these participants were subsequently monitored. Both univariate logistic regression and multivariate logistic regression analyses were conducted to explore the associations between dietary intake variables or general characteristics variables and adverse pregnancy outcomes. Participants with adverse pregnancy outcomes showed a lower intake of iodine and vitamin D, a lower percentage of dietary energy intake from carbohydrates and a higher percentage of dietary energy intake from fats, compared to participants without adverse pregnancy outcomes. The gestational weight gain and family history of diabetes were associated with an increased risk of adverse pregnancy outcomes. Conversely, regular exercise, the intake of iodine and Vitamin D, and the percentage of dietary energy intake from carbohydrates were associated with a decreased risk. The daily diet of pregnant women with GDM in China did not meet the dietary guidelines or DRIs. The low intake of Vitamin D and iodine, the low dietary carbohydrate ratio, family history of diabetes, lack of exercise, and high gestational weight gain were associated with increased risk of adverse pregnancy outcomes in pregnant women with GDM.

Dietary vitamin intake and cancer risk in patients with chronic kidney disease: results from the National Health and Nutrition Examination Survey (2007-2018).

The relationship between vitamin intake and cancer risk in the chronic kidney disease (CKD) population is unknown. For this reason, we investigated the relationship between dietary vitamin intake and cancer risk in CKD patients and looked for effective vitamin dietary patterns. This study included 3518 CKD patients from 2007 to 2018 National Health and Nutrition Examination Survey database. All participants were categorized into four groups based on vitamin intake by K-mean clustering. The data were collected and analyzed from June 2023 to December 2023. A total of 3518 CKD patients with a mean age of (61.8 ± 16.3) years were included in the study. During a median follow-up of 7.3years, 137 participants died of cancer. In the multivariate adjusted cox proportional hazards model for single vitamin intake, vitamin E Q4 intake (reference Q1) reduced cancer mortality (HR (95% CI) = 0.45 (0.24-0.87), P = 0.018). Further plotting of the restricted cubic spline curve revealed a linearly decreasing relationship between vitamin E intake and cancer mortality (Poverall = 0.010 Pnon-linear = 0.163). In the multivariate adjusted cox proportional hazards model for multivitamin co-intake, the vitamin C/K intake group reduced cancer mortality compared to the low vitamin intake group (HR (95% CI) = 0.42 (0.20-0.88), P = 0.022). Increased vitamin C intake was independently associated with reduced cancer risk in CKD patients, and a vitamin dietary pattern with high vitamin C/K intake was also effective in reducing cancer risk.

Maternal use of nitrosatable drugs during pregnancy and adult male reproductive health: A population-based cohort study.

Prenatal exposures to xenobiotics during the masculinization programming window are suggested to impact male fecundity later in life. Frequently used nitrosatable drugs, such as penicillins and beta2-agonists, contain amines or amides that may form teratogenic compounds in reaction with nitrite. We explored whether maternal nitrosatable drug use during gestation was associated with biomarkers of male fecundity in adulthood; moreover, the potential modifiable effect of nitrate and vitamin intake was investigated. We performed a cohort study in the Fetal Programming of Semen Quality cohort that includes semen characteristics, reproductive hormone concentrations, and measures of testis size on 1058 young adult sons in the Danish National Birth Cohort. Information on maternal use of nitrosatable drugs was obtained from questionnaires and interviews around gestational weeks 11 and 16. A multivariable negative binomial regression model was used to obtain relative differences in biomarkers of male fecundity for those whose mothers used nitrosatable drugs compared to those without such maternal use. In sub-analyses, the exposure was categorized according to nitrosatable drug type: secondary amine, tertiary amine, or amide. We investigated dose dependency by examining the number of weeks with intake and explored potential effect modification by low versus high maternal nitrate and vitamin intake from diet and nitrate concentration in drinking water. We added selection weights and imputed values of missing covariates to limit the risk of selection bias. In total, 19.6% of the study population were born of mothers with an intake of nitrosatable drugs at least once during early pregnancy. Relative differences in biomarkers related to male fecundity between exposed and unexposed participants were negligible. Imputation of missing covariates did not fundamentally alter the results. Furthermore, no sensitive subpopulations were detected. The results suggest that maternal use of nitrosatable drugs does not have a harmful influence on the male fecundity of the offspring.

Triple burden of malnutrition among Malaysian children aged 6 months to 12 years: current findings from SEANUTS II Malaysia.

This paper aims to report South East Asian Nutrition Surveys (SEANUTS) II Malaysia data on nutritional status, dietary intake and nutritional biomarkers of children aged 6 months to 12 years. Cross-sectional survey conducted in 2019-2020. Multistage cluster sampling conducted in Central, Northern, Southern and East Coast regions of Peninsular Malaysia. 2989 children aged 0·5-12·9 years. Prevalences of stunting, thinness, overweight and obesity among children aged 0·5-12·9 years were 8·9 %, 6·7 %, 9·2 % and 8·8 %, respectively. Among children below 5 years old, 11·4 % were underweight, 13·8 % had stunting and 6·2 % had wasting. Data on nutritional biomarkers showed that a small proportion of children aged 4-12 years had Fe (2·9 %) and vitamin A deficiencies (3·1 %). Prevalence of anaemia was distinctly different between children below 4 years old (40·3 %) and those aged 4 years and above (3·0 %). One-fourth of children (25·1 %) had vitamin D insufficiency, which was twice as prevalent in girls (35·2 % v. boys: 15·6 %). The majority of children did not meet the recommended dietary intake for Ca (79·4 %) and vitamin D (94·8 %). Data from SEANUTS II Malaysia confirmed that triple burden of malnutrition coexist among children in Peninsular Malaysia, with higher prevalence of overnutrition than undernutrition. Anaemia is highly prevalent among children below 4 years old, while vitamin D insufficiency is more prevalent among girls. Low intakes of dietary Ca and vitamin D are also of concern. These findings provide policymakers with useful and evidence-based data to formulate strategies that address the nutritional issues of Malaysian children.

Nutritional status assessment using anthropometry and evaluation of school canteen menus in Tanzania

Abstract Background According to the FAO, an estimated 767.9 million people faced hungry in 2021. To improve food sovereignty, it is necessary to investigate eating habits and assess the actual level of malnutrition. The study took place in two private schools, one primary and one secondary school in the Rukwa region, one of the poorest in Tanzania, with a human development index of 0.467. Methods Height and weight were measured from March to June 2022 on a sample of 235 students (52% male, age 9.9 ± 2.6) from the primary school and 297 (61% male, age 16.9 ± 2.8) from the secondary school. The menus of the canteens were evaluated by weighing the ingredients cooked for one week and dividing the estimated nutrients for each student attending the canteen, then comparing them with the EFSA Dietary Reference Values. Results The BMI by age of children from 5 to 19 years was compared with the WHO reference data for growth. 72.7% of primary school students were in the 50th percentile and 27.7% in the 15th percentile, while 68.7% of secondary school students were in the 50th percentile and 25.4% in the 15th percentile. The menu evaluation showed that carbohydrates provide 79.6% of the diet's energy, while lipids only 10.58%. Vitamin intake was particularly low for B7 (3.05μg), B12 (0.155μg), A (149.21μg), D (0.04μg) and K (0.57μg). Among the minerals, the greatest deficiencies are Calcium (290mg), Magnesium (39.95mg) Iodine (18.63µg), Copper (0.20mg), Selenium (1.38µg) and Manganese (0.46mg). Conclusions The results show that children and adolescents are growing less than recommended and malnutrition affects the youngest. The meals in the two canteens show a shortage of several nutrients, easily attributable to the low consumption of fruit and animal products. Although the situation appears critical, it should be emphasised that the schools surveyed were private, while in public schools the catering service does not exist, often condemning students to a single evening meal. Key messages • In a rural context of Tanzania, children and adolescents are growing less than recommended and malnutrition affects the youngest. • A low intake of vitamins and minerals was detected in two school canteens in Tanzania.

Dietary, macronutrient, micronutrient, and nutrigenetic factors impacting cardiovascular risk markers apolipoprotein B and apolipoprotein A1: a narrative review.

Genetic predisposition and dietary factors can impact cardiovascular disease (CVD) risk. Two important markers in assessing CVD risk are apolipoprotein (apo) B and apolipoprotein A1 plasma levels. These markers are measured as a ratio, with a high apoB:apoA1 ratio associated with increased CVD risk. Dietary and lifestyle recommendations are the cornerstone of managing primary and secondary CVD risk-mitigation strategies. One way to assess the impact of various dietary and lifestyle interventions on CVD risk is to evaluate the changes in CVD risk markers, such as apoB, apoA1, and apoB:apoA1 ratio. Various human studies have demonstrated the impact of dietary, macronutrient, and micronutrient interventions on apoB and apoA1 status. This review aims to elucidate dietary, macronutrient, micronutrient, and nutrigenetic considerations for impacting apoB and apoA1 levels. A low-carbohydrate, high-saturated-fat diet, low fiber intake, low vitamin and mineral intake, and zinc and iron deficiency are associated with an elevated apoB:apoA1 ratio. The Mediterranean diet, vegan diet, fermented dairy products, lower sugar intake, higher protein intake, higher polyunsaturated fat intake, and an omega-3-rich diet are associated with a decreased apoB:apoA1 ratio. Micronutrients associated with a decreased apoB:apoA1 ratio include vitamin D sufficiency, increased serum vitamin C, and magnesium. Variants in the APOE, APOA1, and FADS2 genes may alter the apoB:apoA1 ratio in response to various dietary interventions. When accounting for factors that may favorably alter the apoB:apoA1 ratio, researchers should consider a healthy diet sufficient in polyunsaturated fats, vitamins, minerals, trace minerals, and lower excess sugars.

Assessment of dietary intake of Vitamin A-rich foods and associated factors among lactating mothers attending Lunga Lunga Health Centre, in Sinai slum, Nairobi County, Kenya

Vitamin A deficiency is a problem of public health significance among lactating mothers. Low dietary intake of vitamin A results in inadequate vitamin A concentration in breastmilk, thereby putting the life of the breastfed child at risk. Food availability is critical for quality nutrition that leads to a balanced diet. The poor in urban areas spend most of their income on food yet do not meet their dietary needs. This study aimed to assess the dietary intake of vitamin A rich foods, prevalence of undernutrition and household food insecurity among lactating mothers (15-49 years) attending Lunga Lunga Health Centre from Sinai Slum, Nairobi, Kenya. This cross-sectional study was undertaken using systematic random sampling for 384 lactating mothers from April to June 2017. A structured questionnaire was used to obtain socio-demographic information. Dietary intake was assessed using a 24-hour recall and Food Frequency Questionnaire (FFQ). Prevalence of undernutrition was determined through anthropometric measurements: Body Mass Index (BMI) and Mid Upper Arm Circumference (MUAC). Household food security was determined using food insecurity access scale and dietary diversity questionnaires. Statistical analysis was undertaken using Microsoft excel and SPSS. Chi-square test was used to determine for associations between inadequate intake of vitamin A, maternal undernutrition, household food security and socio-demographics. Logistic regression analysis determined the predictors of adequate dietary intake of vitamin A, undernutrition and food security. The mean age of the lactating mothers was 26.5 (SD 5.6) years. Majority (72.9%) had primary education while 57.6% were self-employed. Inadequate dietary intake of vitamin A was reported amongst 58.6% of the mothers, 31.3% had low MUAC&lt;220mm while 13.8% had low BMI. Mothers who consumed dark green leafy vegetables were 26.6% compared to those consuming fruits like bananas (18.2%), mangoes (13.3%), pineapple (10.7%) and papaya (8.3%). Fish formed the main source of proteins (18.8%), followed by meat (16.7%) and eggs (14.8%). Vitamin A intake had a significant association with income (p&lt;0.001), energy (p&lt;0.001), food insecurity (p&lt;0.001) and buying food (p&lt;0.001). Household Dietary Diversity Score (HDDS) had a significant association with low MUAC (χ2 = 1.694, p =0.031 and low BMI (χ2 = 3.039, p = 0.042). Lactating mothers from Sinai slum had inadequate dietary vitamin A intake, were under nourished and food insecure. Food security interventions: food-based strategies and policies that include Vitamin A food fortification aimed at increasing intake of Vitamin A rich food, campaigns for increased dietary diversity, alongside routine nutrition education among mothers should be emphasized to enhance their nutritional status and reduce micronutrient deficiencies. Key words: Vitamin A, Nutritional status, Slum, dietary diversity, Food Frequency

Food and Nutrient Consumption Patterns of Filipino Pregnant and Lactating Women Based on a Nationwide Survey

Due to the limited studies focusing on micronutrient intakes of pregnant and lactating women,and important dietary sources in the Philippines, this study aims to provide an insight into the food and nutrient consumption pattern of pregnant and lactating women. The objectives were to: [1] identify the food groups commonly consumed and dietary patterns of Filipino pregnant and lactating women; [2] describe the macro- and micronutrient intakes of these women; [3]assess the adequacy of these intakes against dietary references; and [4] identify important food sources of their energy and nutrient intakes. This study involved a cross-sectional secondary analysis of the data of 1,474 pregnant women and 4,571 lactating women covered in the 2018–2019 Expanded National Nutrition Surveys (ENNS). Food and beverage intakes were collected using a 24-h food recall method. Energy and nutrient intakes were calculated and analyzed in relation to the Philippine Dietary Reference Intakes (PDRI). Dishes predominantly consumed by pregnant and lactating women were comprised of rice and rice products, fish and products,and vegetables. Cereal consumption is higher, whereas there was a low consumption of meat,milk and dairy products, eggs, dried beans, nuts, and seeds, starchy roots and tubers, and fruits.The mean energy intakes of pregnant and lactating women were below the recommended energy intake (REI). The majority of pregnant (83.6%) and lactating (81.2%) had intakes below theestimated average requirement (EAR) for protein. Mean intakes of all micronutrients except niacin and phosphorous were below the EAR. Iron, calcium, vitamin C, and riboflavin intakes were furthest from the EAR. Less than 1% of pregnant and lactating women met the EAR for iron, whereas less than 10% met the EAR for vitamin A. Rice and rice products were the most important dietary sources of energy, protein, iron, thiamin, riboflavin, niacin, and phosphorus in the diet of pregnant and lactating women. The findings of this study reflect the low intakes of energy, protein, vitamins, and minerals due to poor dietary quality and food sources, thus increasing the risk of nutrient deficiency among Filipino pregnant and lactating women.

Association of bone mineralization markers with dietary nutrient intake in adolescents with and without biochemical osteomalacia.

Dietary intake is widely known to play a crucial role in achieving peak bone mass among children and adolescents. Unfortunately, this information is lacking among Arab adolescents, an understudied demographic that has recently been observed to have a high prevalence of abnormal mineralization markers [low serum 25(OH)D, high serum alkaline phosphatase (ALP), low calcium (Ca) and/or inorganic phosphate (Pi)] suggestive of biochemical osteomalacia (OM, defined as any 2 of the 4 parameters). In order to fill this gap, we aimed to evaluate the associations of serum markers of biochemical OM with dietary intake of macronutrients, vitamins and trace minerals. Saudi adolescents (N = 2,938, 57.8% girls), aged 12-17 years from 60 different schools in Riyadh, Saudi Arabia were included. Dietary intake of nutrients was calculated following a semi-quantitative 24 h dietary recall over 3 weekdays and 1 weekend-day using a validated food frequency questionnaire. Compliance to reference daily intake (RDI) of macronutrients, vitamins and trace minerals were calculated. Fasting blood samples were collected and circulating levels of 25(OH)D, ALP, Ca, and Pi were analyzed. A total of 1819 (1,083 girls and 736 boys) adolescents provided the dietary recall data. Biochemical OM was identified in 175 (9.6%) participants (13.5% in girls, 3.9% in boys, p < 0.01) while the rest served as controls (N = 1,644). All participants had serum 25(OH)D levels <50 nmoL/L. Most participants had very low dietary intakes of Ca (median ~ 290 mg) and vitamin D (median ~ 4 μg) which are far below the RDI of 1,300 mg/day and 20 μg/day, respectively. In contrast, excess dietary intakes of Pi, Na, K, and Fe were observed in all participants. In the biochemical OM group, thiamine and protein intake were significant predictors of serum 25(OH)D, explaining 4.3% of the variance perceived (r = 0.23, adjusted r2 = 4.3%, p = 0.01). Among controls, dietary vitamin C and vitamin D explained 0.6% of the total variation in serum 25(OH)D (r = 0.09, adjusted r2 = 0.6%, p = 0.004). Arab adolescents do not meet the RDI for dietary Ca and vitamin D, and none have sufficient vitamin D status (25(OH)D levels >50 nmol/L) but they exceed the RDI for dietary Pi. Interpreting these data in the light of the increased prevalence of rickets in Arab countries, food fortification to optimise vitamin D and Ca intake in Saudi adolescents should be considered.

Dietary Intake of Micronutrients and Disease Severity in Patients with Amyotrophic Lateral Sclerosis.

Vitamins and essential metals have been studied as potential risk and prognostic factors in amyotrophic lateral sclerosis (ALS). This study aimed to evaluate the prevalence of inadequate micronutrient intake in ALS patients, comparing subgroups according to the disease severity. Data were obtained from the medical records of 69 individuals. Assessment of disease severity was determined by the revised ALS Functional Scale (ALSFRS-R), using the median as the cutoff. The prevalence of inadequate micronutrient intake was estimated using the Estimated Average Requirements (EAR) cut-point method. The prevalence of inadequate vitamin D, E, riboflavin, pyridoxine, folate, cobalamin, calcium, zinc, and magnesium intake was considered severe. Patients with lower ALSFRS-R scores had lower intakes of vitamin E (p < 0.001), niacin (p = 0.033), pantothenic acid (p = 0.037), pyridoxin (p = 0.008), folate (p = 0.009) and selenium (p = 0.001). Therefore, ALS patients should be monitored regarding dietary intake of micronutrients essential in neurological processes.

EFEKTIVITAS PUDING JAMBU BIJI MERAH TERHADAP PENURUNAN TEKANAN DARAH PADA PREHIPERTENSI DI PUSKESMAS PADASUKA KOTA BANDUNG

Prehypertension is an early condition that can cause arterial hypertension in its later development into cardiovascular disease. Low intake of vitamin C and high intake of sodium at productive age have the risk of triggering the development of degenerative diseases such as hypertension. This study aims to determine the effectiveness of giving guava pudding on blood pressure in the prehypertension group in the work area of ​​the Padasuka Public Health Center, Bandung City. This type of research is a quasi two group with a control experimental design using pre-test and post-test. The sampling technique used is simple random sampling. Intake data were collected using a Semiquantitative Food Frequency Questionnaire (SFFQ) method while blood pressure data was measured using a Digital Sphygmomanometer. The research data were analyzed using Paired T-Test and Wilcoxon test. The results showed that the average intake of vitamin C in the treatment group increased by 186% and sodium intake decreased by 19.1%, better than the control group, the decrease in systolic blood pressure in the treatment group was 3.2% or higher than the control group and an average The treatment group's diastolic blood pressure decreased 5.2% or lower than the control group. There was an effect of the intervention on the intake of vitamin c and sodium in the treatment group (p&lt;0.05). There was an effect on vitamin c intake (p&lt;0.05) and no effect on sodium intake in the control group (p&gt;0.05). The results of the study on systolic blood pressure in the treatment group showed an effect of giving the intervention product (p&lt;0.05) while the diastolic blood pressure in the treatment group, systolic blood pressure, and diastolic blood pressure in the control group showed no effect on giving the intervention product (p&gt;0.05). The study concluded that there was an effect of giving red guava pudding on systolic blood pressure, but there was no difference in the decrease in systolic and diastolic blood pressure between the two sample groups.

Dose-response association between dietary folate and niacin intakes with diabetes among Chinese adults: a cross-sectional study

BackgroundThe aim of this study was to examine the relationship between dietary intake of folate and niacin and diabetes risk in Chinese adults.MethodsThis is a cross-sectional study. Demographic and anthropometric data along with information on dietary intake of vitamins were collected, and eligible participants were recruited to complete the questionnaire. A binary logistic regression analysis was conducted to examine the association between dietary intake of vitamins and diabetes risk, with adjustment for potential confounders. Non-linear dose-response relationships between dietary intake of folate and niacin and diabetes risk were also evaluated using adjusted restricted cubic splines.ResultsOf the 3106 eligible participants, 15.9% had diabetes. Median folate was significantly higher in diabetic patients than in controls (32.030 vs. 27.600 gμ), while median niacin was significantly lower (7.000 vs. 7.900 mg). After controlling for potential confounders, binary logistic regression analysis showed that each unit increase in folate intake was associated with a 1.002-fold increase in the risk of developing diabetes (odds ratio (OR) = 1.002; 95% confidence interval (CI) 1.000–1.004; P = 0.022), while each unit increase in niacin intake was associated with a 3.5% reduction in diabetes risk (OR = 0.965; 95% CI 0.944–0.986; P = 0.001). The plots of restricted cubic splines presented an atypical inverted U-shaped association between dietary intake of folate and diabetes risk.ConclusionsDiabetic patients had a low intake of vitamins, especially the B vitamins. Dietary intake of folate and niacin tended to be independently associated with the risk of diabetes. Nevertheless, this study is observational and a large-scale randomized controlled trial is yet to be conducted, which will add to the evidence of the study results.

Natural Vitamin E Supplementation during Pregnancy in Rats Increases RRR-α-Tocopherol Stereoisomer Proportion and Enhances Fetal Antioxidant Capacity, Compared to Synthetic Vitamin E Administration

Introduction: Low dietary intake of vitamin E is a global public health issue. RRR-α-tocopherol (RRR-αT) is the only naturally occurring vitamin E stereoisomer, but the equimolecular mixture of all eight stereoisomers, synthetic vitamin E (S-αT), is commonly consumed. The objective of this study was to evaluate bioavailability and antioxidant activity of RRR-αT versus S-αT, in both mother and fetus, after maternal supplementation during pregnancy. Methods: Female rats (7 weeks of age) received a modified AIN-93G diet supplemented with 75 IU/kg of RRR-αT (NVE, n = 20) or S-αT (SVE, n = 17). At delivery, the levels of αT, stereoisomer distribution, and antioxidant capacity were analyzed in maternal and fetal plasma. Results: NVE administration significantly increased the proportion of RRR-αT stereoisomer in maternal and fetal plasma. The percentage of RRR-αT increased from 32.76% to 88.33% in maternal plasma, and 35.25% to 97.94% in fetal plasma, in the NVE group compared to SVE. Fetal plasma from the NVE group was found to have higher total antioxidant capacity compared to SVE. Lastly, fetal plasma RRR-αT stereoisomer percentage was positively associated with expression levels of scavenger receptor class B type 1 (SR-B1) in the placenta. Conclusions: Both natural and synthetic sources of vitamin E showed similar bioavailability. Still, NVE supplementation increased the proportion of RRR-αT and promoted higher antioxidant activity in fetal plasma at birth. Placental SR-B1 might be involved in the stereoselective transfer of RRR-αT stereoisomer across the placenta and may improve αT bioactivity in the fetus.

Ultra-processed food (UPF) intake in pregnancy and maternal and neonatal outcomes.

Ultra-processed food (UPF), as defined by the NOVA classification, is related to lower diet quality, which may adversely affect maternal health and neonatal outcomes. This study aims to describe nutrient intake of pregnant women by the share of UPF in the diet and to identify associations between UPF intake and maternal and neonatal outcomes. In this cross-sectional study, pregnant women (n = 206) were recruited upon arrival to the obstetrics ward for delivery, and asked to complete a Food Frequency Questionnaire (FFQ), and questionnaires regarding environmental exposures, and socio-demographic characteristics. Neonatal measurements and clinical data were obtained following delivery. UPF energy intake was expressed as absolute and in terms of percent from total energy. Women with high intake of energy from UPF were compared to those with low intake. Among 206 pregnant women, dietary intake of UPF ranged from 15.6% to 43.4% of total energy in the first and fourth quartiles of UPF consumption, respectively. Women in the fourth quartile of energy from UPF had lower intakes of vitamin C, beta-carotene, vitamin B6, and potassium, which is indicative of inferior diet quality. Percent energy from UPF was associated with maternal obesity (BMI ≥ 30) (OR = 1.06, 95% CI: 1.06, 1.10, p = 0.008) and shorter male infant ano-genital distance (AGD) (B = -1.9, 95% CI: -3.5, -0.24, p = 0.02). UPF intake during pregnancy is associated with undesirable maternal and neonatal outcomes and more research is needed to confirm these findings.

Nutritional factors of bone health in athletes

The importance of proper nutrition when playing sports is difficult to overestimate. Athletes of any age need to consume a sufficient amount of macro- and micronutrients for bone health. High-quality and balanced nutrition in terms of quantity and composition is important for optimal recovery after training, adaptation to intense physical activity and prevention of sports injuries. The aim of the study was to summarize the current data of domestic and foreign literature on the factors affecting bone mineral density (BMD) in athletes, as well as to consider the key points of nutritional support necessary for the prevention and treatment of osteoporosis. Material and methods. The search was conducted using the Google Academy search engine and electronic databases PubMed, MEDLINE, EMBASE, Scopus, Web of Science, eLIBRARY for the period from 2008 to 2022. For the search, we used keywords and their combinations: "athletes", "osteoporosis", "stress fractures", "calcium" and "vitamin D". Results and discussion. Bone health is influenced by many factors, the most significant of which are lifestyle and the nature of a person's physical activity. Despite strong evidence for the benefits of exercise for bone health, there are sports that predispose to low BMD and increase the risk of osteoporosis. First of all, athletes involved in aerobic and aesthetic disciplines (long-distance running, cycling, swimming, rhythmic gymnastics, dancing, etc.) are at risk. In addition, factors that predispose to a decrease in BMD include female gender, low intake of energy substrates, protein, vitamin D and calcium, and certain medications. Of great importance for the regulation of bone metabolism and maintaining optimal BMD are the genetic characteristics of the athlete. The main adverse consequences for athletes with reduced BMD are fractures of various localization. At the same time, the problem of a high risk of developing stress injuries of bones is especially relevant. Calcium and vitamin D are key nutritional factors needed to maintain bone health. Optimal intake of carbohydrates, proteins, and polyunsaturated fatty acids is also important. There is evidence of a positive effect on the skeletal system of such nutritional factors as potassium, magnesium, sodium, vitamins K, C, B12 and folic acid. The specific mechanisms of the influence of these micronutrients on bone metabolism and the relationship of their consumption level with BMD need further research. Conclusion. Thus, athletes of all ages and specializations need to pay great attention to the state of the skeletal system. Given the association between the risk of osteoporosis and malnutrition, it is essential for athletes to maintain an optimal nutritional status and consume adequate amounts of vitamins and minerals.
