Dietary Intake Of Micronutrients Research Articles

Dietary micronutrients intake and its effect on haemoglobin levels of pregnant women for clinic visit in the Mount Cameroon health area: a cross-sectional study.

Nutritional deficiencies and its consequences such as anaemia are frequent among pregnant women residing in under resource settings. Hence, this study sought to investigate specific dietary micronutrient inadequacy and its effect on maternal haemoglobin levels. This institution based cross-sectional survey enrolled 1,014 consenting pregnant women consecutively. Data on socio-demographic, economic and antenatal characteristics were recorded using a structured questionnaire. Minimum dietary diversity for women (MDD-W) was assessed using the 24-h recall method and haemoglobin (Hb) concentration (g/dL) determined using a portable Hb metre. Significant levels between associations was set at p < 0.05. Among those enrolled, 40.9% were anaemic while 89.6% had inadequate dietary nutrient intake. In addition, uptake of blood supplements, haem iron, plant and animal-based foods rich in vitamin A were 71.5, 86.2, 35.5 and 12.6%, respectively. Moreover, anaemia prevalence was significantly (p < 0.05) lower in women who took iron-folic acid along with food groups rich in haem iron (38.5%) or both plant and animal vitamin A (29.0%). Besides, mean maternal Hb levels was significantly (p < 0.001) higher in women who consumed haem iron (11.08 ± 1.35) and vitamin A food groups (11.34 ± 1.30) when compared with their counterparts who did not consume haem iron (10.54 ± 1.19) and vitamin A food groups (10.74 ± 1.31). Dietary uptake of foods rich in haem-iron and vitamin A significantly improves Hb levels in Cameroonian pregnant women. Our findings underscore the importance of improving maternal nutritional awareness and counselling during antenatal period to reduce the anaemia burden.

Micronutrient intake from complementary foods of Asian New Zealand infants

The complementary feeding period (6-23 months of age) is when solid foods are introduced alongside breastmilk or infant formula and is the most significant dietary change a person will experience. The introduction of complementary foods is important to meet changing nutritional requirements(1). Despite the rising Asian population in New Zealand, and the importance of nutrition during the complementary feeding period, there is currently no research on Asian New Zealand (NZ) infants’ micronutrient intakes from complementary foods. Complementary foods are a more easily modifiable component of the diet than breastmilk or other infant milk intake. This study aimed to compare the dietary intake of micronutrients from complementary foods of Asian infants and non-Asian infants in NZ. This study reported a secondary analysis of the First Foods New Zealand cross-sectional study of infants (aged 7.0-9.9 months) in Dunedin and Auckland. 24-hour recall data were analysed using FoodFiles 10 software with the NZ food composition database FOODfiles 2018, and additional data for commercial complementary foods(2). The multiple source method was used to estimate usual dietary intake. Ethnicity was collected from the main questionnaire of the study, answered by the respondents (the infant’s parent/caregiver). Within the Asian NZ group, three Asian subgroups were identified – South East Asian, East Asian, and South Asian. The non-Asian group included all remaining participants of non-Asian ethnicities. Most nutrient reference values (NRV’s)(3) available for the 7-12 month age group are for total intake from complementary foods and infant milks, so the adequacy for the micronutrient intakes from complementary foods alone could not be determined. Vitamin A was the only micronutrient investigated in this analysis that had an NRV available from complementary foods only, allowing conclusions around adequacy to be made. The Asian NZ group (n = 99) had lower mean group intakes than the non-Asian group (n = 526) for vitamin A (274µg vs. 329µg), and vitamin B12 (0.49µg vs. 0.65µg), and similar intakes for vitamin C (27.8mg vs. 28.5mg), and zinc (1.7mg vs. 1.9mg). Mean group iron intakes were the same for both groups (3.0mg). The AI for vitamin A from complementary foods (244µg) was exceeded by the mean intakes for both groups, suggesting that Vitamin A intakes were adequate. The complementary feeding period is a critical time for obtaining nutrients essential for development and growth. The results from this study indicate that Asian NZ infants have lower intakes of two of the micronutrients of interest than the non-Asian infants in NZ. However, future research is needed with the inclusion of infant milk intake in these groups to understand the total intake of the micronutrients. Vitamin A intakes do appear to be adequate in NZ infants.

Higher dietary methyl donor micronutrient consumption is associated with higher muscle strength in adults: a cross-sectional study.

Methyl donor micronutrients might affect muscle strength via DNA methylation. We aimed to evaluate the combined relationship of dietary methyl donor micronutrients containing betaine, choline, methionine, vitamin B12, vitamin B6 and folate on muscle strength. This cross-sectional study was conducted on 267 subjects including 113 men and 154 women. Dietary intake of micronutrients was assessed utilising a validated 168-item semi-quantitative FFQ, and methyl donor micronutrient score (MDMS) was calculated. The muscle strength of the participants was measured using a digital handgrip dynamometer. The association was determined using linear regression analysis. The mean age of participants was 36·8 ± 13·2 years. After taking into account potential confounding variables, there was no significant association between dietary methyl donor micronutrient score (MDMS) and the mean left-hand muscle strength (β: 0·07, se: 0·05, P = 0·07); however, the changes were significant in the mean right-hand muscle strength (β: 0·09, se: 0·04, P = 0·03). There was also a significant positive relationship between mean muscle strength and methyl donors' intake after fully adjusting for potential confounders (β: 0·08, se: 0·04, P = 0·04). In conclusion, our findings revealed that higher dietary methyl donor micronutrient consumption is associated with enhanced muscle strength. As a result, advice on a higher intake of methyl donor-rich foods including grains, nuts, dairy products and seafood might be recommended by dietitians as a general guideline to adhere to. Additional prospective studies are needed to confirm the findings.

L’apport alimentaire en micronutriments dans le trouble du spectre de l’autisme chez des enfants de l’ouest Algérien

Autism Spectrum Disorders (ASD) can affect the nutritional status of children. This study aimed to assess the daily dietary intakes (DDI) of micronutrients, as well as the frequency of consumption (FC) of different food groups, in children with ASD and compare them to those with typical development (TD). It will also determine to what extent these intakes comply with the Recommanded Dietary Allowances (RDA). The study included 52 children, 26 with ASD and 26 with TD. DDI and FC were gathered using a 7-day food diary. Among the DDI of micronutrient, only Vit B12 showed a significant difference between cases and controls, but the DDI was higher than the recommendations in both groups studied. All the children of our study sample had DDI lower than the RDA, in iron, calcium, vitamins E and K1. However, the most notable discrepancy with the recommendations was observed in iron intake (6.95±2.87mg/d vs 7.04±2.98mg/d, p>0.05; RDA equal to 10mg/d) primarily due to low consumption of meat products, and in calcium (406.96mg/d vs 399.46mg/d, p>0.05; RDA of 1000mg/d). Most of the children in this study had a FC of dairy products below the recommended consumption frequency. This study highlights the importance of improving dietary guidance for both groups studied, with particular attention to children with ASD to avoid any complications of ASD.

Estimated energy and nutrient intake in complementary feeding methods in Brazilian infants: randomized clinical trial

Inadequate nutrient intake during complementary feeding (CF) can affect healthy infant growth and development. A randomized clinical trial was conducted to examine the energy and nutrient intake in Brazilian children randomly assigned to three distinct CF methods. Mother-infant pairs participated in the study, with mothers receiving interventions in one of three CF approaches: (A) strict Parent-Led Weaning (PLW); (B) strict Baby-Led Introduction to Solids (BLISS); and (C) a mixed method. Assessments were made at 5.5 months, nine months, and 12 months of the child's age. Food consumption was measured through 24-h dietary recalls at nine and 12 months, with intake estimates calculated using the Brazilian Food Composition Table. Means or medians of energy and nutrients were compared between groups using ANOVA with Tukey's post hoc test or the Kruskal–Wallis test. A total of 115 infants were evaluated at nine months, and 102 at 12 months. Children in the PLW, BLISS, and mixed method groups exhibited comparable dietary intakes of energy, macronutrients, and micronutrients at both nine and 12 months. Infants following PLW, BLISS, and mixed methods demonstrated similar levels of energy and nutrient intake, underscoring the effectiveness of these strategies in ensuring comparable nutrient intake during the critical phase of CF.Trial registration The trial was registered in the Brazilian Registry of Clinical Trials (ReBEC) with identifier [RBR-229scm U1111-1226-9516], [https://ensaiosclinicos.gov.br/rg/RBR-229scm]. The full data of the first registration was on 24/09/2019.

Effect of multiple micronutrient-fortified bouillon on micronutrient status among women and children in the Northern Region of Ghana: Protocol for the Condiment Micronutrient Innovation Trial (CoMIT), a community-based randomized controlled trial.

Micronutrient deficiencies are prevalent in West Africa, particularly among women of reproductive age (WRA) and young children. Bouillon is a promising food fortification vehicle due to its widespread consumption. This study aims to evaluate the impact of multiple micronutrient-fortified bouillon cubes, compared to control bouillon cubes (fortified with iodine only), on micronutrient status and hemoglobin concentrations among lactating and non-lactating WRA and young children in northern Ghana. This randomized, controlled doubly-masked trial will be conducted in the Kumbungu and Tolon districts in the Northern Region of Ghana, where prior data indicate multiple micronutrient deficiencies are common. Participants will be: 1) non-pregnant non-lactating WRA (15-49 y), 2) children 2-5 y, and 3) non-pregnant lactating women 4-18 months postpartum. Eligible participants will be randomly assigned to receive household rations of one of two types of bouillon cubes: 1) a multiple micronutrient-fortified bouillon cube containing vitamin A, folic acid, vitamin B12, iron, zinc, and iodine, or 2) a control cube containing iodine only. Each participant's household will receive a ration of bouillon cubes every 2 weeks, and households will be advised to prepare meals as usual, using the study-provided cubes. The trial duration will be 9 months for non-pregnant non-lactating WRA and children, and 3 months for lactating women. The primary outcomes will be changes in biomarkers of micronutrient status and hemoglobin among WRA and children and milk micronutrient concentrations among lactating women. Secondary outcomes will include change in prevalence of micronutrient deficiency and anemia; dietary intake of bouillon and micronutrients; inflammation, malaria, and morbidity symptoms; and child growth and development. Evidence from this study will inform discussions about bouillon fortification in Ghana and West Africa. The trial was registered on ClinicalTrials.gov (NCT05178407) and the Pan-African Clinical Trial Registry (PACTR202206868437931). This manuscript reflects protocol version 4 (August 29, 2022).

Trends in Dietary Micronutrient Adequacy in Young Adults Over the Latest 25 Years in Japan.

It has been assumed that economically developed countries are well nourished compared to developing countries, but little is known about how economic status affects dietary micronutrient intake in the future childbearing generation. We analyzed the trend of dietary micronutrient adequacy in young adults in Japan, as one of the representative countries with advanced dietary habits and economic progress. We conducted a retrospective analysis using 2 web-accessible databases, namely the Japanese National Health and Nutrition Survey and the World Development Indicators. Japan has been facing a progressive insufficiency of dietary vitamins A and C and iron, especially among young adults, over the past 25 years. The hidden progression of silent malnutrition has become more apparent since the 2010s, coinciding with a series of economic recessions and natural disasters. Given that parental dietary habits play a critical role in ensuring a balanced diet for their children, our findings underscore the importance of proactive nutrition counseling and education, especially for young adults of childbearing age who have been identified as vulnerable to micronutrient deficiencies. In line with this policy, we would like to suggest the use of digital transformation platforms as a potential solution in the future, especially for the digital native population.

Dietary Micronutrient Intake and Its Relationship with the Malnutrition–Inflammation–Frailty Complex in Patients Undergoing Peritoneal Dialysis

Background: The relationship between dietary patterns and the malnutrition–inflammation–frailty complex in patients undergoing peritoneal dialysis (PD) is currently unknown. Our objective was to measure dietary nutrient intake and evaluate its association with malnutrition, inflammation, and frailty. Methods: We prospectively recruited adult PD patients. We assessed their dietary nutrient intake using a food frequency questionnaire. Frailty, malnutrition, and inflammation were evaluated by validated Frailty Score (FQ), Subjective Global Assessment (SGA), and Malnutrition-Inflammation Score (MIS). Results: A total of 209 patients were recruited for the study. Among them, 89 patients (42.6%) had an insufficient protein intake, and 104 patients (49.8%) had an insufficient energy intake. Additionally, 127 subjects were identified as frail, characterized by being older (61.9 ± 9.5 vs. 55.6 ± 12.8, p &lt; 0.001), malnourished (SGA: 21.0 ± 2.7 vs. 22.7 ± 3.1, p &lt; 0.001), and having a high inflammation burden (MIS: 10.55 ± 3.72 vs. 7.18 ± 3.61, p &lt; 0.001). There was a significant correlation between dietary zinc intake and body mass index (r = 0.31, p &lt; 0.001), SGA (r = 0.22, p = 0.01), and MIS (r = −0.22, p = 0.01). In the multivariate model, a higher dietary zinc intake predicted a higher SGA (beta 0.03, p = 0.003) and lower FQ (beta −0.38, p &lt; 0.001) and MIS (beta −0.14, p &lt; 0.001), indicating a better nutrition, less frail and inflamed state. A higher dietary zinc intake was also associated with a lower odds of being frail (adjusted odds ratio 0.96, p = 0.009). Conclusion: Dietary inadequacy and micronutrient deficiency are common among the PD population. Dietary zinc intake is independently associated with an improved nutrition, physical condition, and reduced inflammatory state.

A review of the dietary diversity and micronutrient adequacy among the women of reproductive age in low- and middle-income countries.

The dietary quality of women of reproductive age (WRA) is particularly important during preconception, conception, and pregnancy for themselves and their offspring. Poorly diversified diets resulting in inadequate micronutrient consumption may have adverse effects on their health. This narrative review summarizes the findings of studies reporting on dietary diversity and micronutrient intake by WRA in low- and middle-income countries (LMICs). Studies on WRA aged 15-49 years in LMICs, with a sample size of more than 150, report dietary diversity and multiple micronutrient intake based on 24-h dietary recall/food weighed record/food frequency questionnaire, and published between January 2011 and June 2021 were included. The results were compared to the Food and Agriculture Organization (FAO) recommended cut-off for dietary diversity and the Indian Council of Medical Research (ICMR) recommended age- and sex-specific estimated average requirements (EARs) for micronutrient intake. This review includes 35 articles, of which 21 focused on dietary diversity and 14 on micronutrient intake. The results showed that WRA in LMICs had inadequate dietary diversity, with mean food group consumption of only 3.0-4.84, and around 42.3%-90% of women consumed inadequately diversified diets (<5 food groups). Additionally, most studies found that WRA did not consume adequate amounts of essential micronutrients, particularly calcium, iron, zinc, vitamin A, thiamin, riboflavin, folate, and vitamin B12. However, the intake of vitamin C, niacin, and vitamin B6 was above the required levels. In conclusion, this review highlights the common inadequacy of dietary diversity and multiple micronutrient intake among WRA in most LMICs. Effective measures involving improving dietary diversity, food fortification with micronutrients, and supplementation programs could help improve the dietary quality and intake of optimal micronutrients by women in LMICs.

Effects of Sanctions on Food Intake of Urban Households in Razavi Khorasan Province, Iran (2017-2019)

Background: Sanctions are a type of forfeit aimed at forcing the subject to obey the desired political will. Since sanctions affect various components of the economic sectors. The purpose of this study is to investigate the effect of sanctions on food intake of households living in Khorasan Razavi province, Iran. Methods: To investigate the effect of sanctions on food intake of households living in Khorasan Razavi province, the survey data of the National Statistics Center of Iran (NSCI) on cost and income was used. 2129 households (number of households in 2017: 702, 2018: 726 and 2019: 701) were studied. In the N4 program, macronutrients and micronutrients were calculated. The studied variables were analyzed based on four income categories. In the SPSS software, quantitative variables of 2017 to 2019 were reviewed by ANOVA test and variables in pairs of the same period were reviewed by post hoc Tukey test. Results: The analysis showed that by intensifying sanctions, the cost of food has increased more than the average of income, and prices of all food groups spesifically healthy food groups have increased. The diet quality index has decreased significantly. The lower-income classes had the most insufficient dietary intake of micronutrients and the gap between dietary intake of different income classes increased during the study. Conclusion: Sanctions have affected the dietary intake due to the rise in the price of food expenditure and as a result people tend to consume cheaper and lower quality food.

Ultra-processed foods, dietary diversity and micronutrient intakes in the Australian population

PurposeThis cross-sectional study aimed to assess the association between ultra-processed foods consumption and dietary diversity and micronutrient intake in Australia.MethodsAs part of the Nutrition and Physical Activity Survey (2011–2012), 12,153 participants aged 2 years and above were recruited and interviewed. Dietary intake data were collected by two 24-h dietary recalls using the Automated Multiple-Pass Method. The NOVA classification system was used to group the food items based on the extent and purpose of industrial food processing. The mean micronutrient contents were calculated for the total diet, and for two diet fractions; one made up entirely of ultra-processed foods (NOVA group 4) and the other consisting of all non-ultra-processed foods (aggregation of NOVA food groups 1 to 3). The mean micronutrient content in the ultra-processed and non-ultra-processed food diet fractions were compared. Dietary diversity was measured using the ten Food Group Indicators (FGI) of the Food and Agriculture Organization and was defined as the sum number of FGIs per individual. Multiple linear regression models were used to assess the association between the quintiles of energy contribution of ultra-processed foods, dietary diversity, and micronutrient intake.ResultsA negative association was found between quintiles of energy contribution of ultra-processed foods and dietary diversity (β = − 0.43; p < 0.001). The overall micronutrient content was lower in the diet fraction dominated by ultra-processed foods compared to the non-ultra-processed food diet fraction in the study population. The dietary contents of vitamins A, E, C, B9, B12, zinc, calcium, iron, magnesium, potassium, and phosphorus were reduced significantly with increased consumption of ultra-processed foods, even after adjustment for sociodemographic factors and dietary diversity.ConclusionThe quintiles of energy contribution of ultra-processed foods were negatively associated with dietary diversity and micronutrient intake in Australia.

MAOA methylation is associated with impulsive and antisocial behaviour: dependence on allelic variation, family environment and diet.

Congenital absence of monoamine oxidase A (MAO-A) activity predisposes to antisocial impulsive behaviour, and the MAOA uVNTR low-expressing genotype (MAOA-L) together with childhood maltreatment is associated with similar phenotypes in males. A possible explanation of how family environment may lead to such behaviour involves DNA methylation. We have assessed MAOA methylation and impulsive/antisocial behaviour in 121 males from the Estonian Children Personality Behaviour and Health Study. Of the 12 CpG sites measured, methylation levels at the locus designated CpG3 were significantly lower in subjects with antisocial behaviour involving police contact. CpG3 methylation was lower in subjects with alcohol use disorder by age 25, but only in MAOA-H genotype. No correlation between MAOA CpG3 methylation levels and adaptive impulsivity was found at age 15, but in MAOA-L genotype a positive correlation appeared by age 18. By age 25, this positive correlation was no longer observed in subjects with better family relationships but had increased further with experience of adversity within the family. MAOA CpG3 methylation had different developmental dynamics in relation to maladaptive impulsivity. At age 18, a positive correlation was observed in MAOA-L genotype with inferior family relationships and a negative correlation was found in MAOA-H with superior home environment; both of these associations had disappeared by age 25. CpG3 methylation was associated with dietary intake of several micronutrients, most notable was a negative correlation with the intake of zinc, but also with calcium, potassium and vitamin E; a positive correlation was found with intake of phosphorus. In conclusion, MAOA CpG3 methylation is related to both maladaptive and adaptive impulsivity in adolescence in MAOA-L males from adverse home environment. By young adulthood, this relationship with maladaptive impulsivity had disappeared but with adaptive impulsivity strengthened. Thus, MAOA CpG3 methylation may serve as a marker for adaptive developmental neuroplasticity in MAOA-L genotype. The mechanisms involved may include dietary factors.

The Nutritional Needs of Mothers and Babies: A Review

The aim is to assess the importance of measuring healthy habits by pregnant women, that enhance different factors of mother and fetus health. We evaluate the change and variations in dietary recommendations. A female went through a lot of physical and mental changes in different stages of pregnancy and there are some common symptoms such as vomiting, fatigue, nausea, frequent urination, dizziness, etc. Certain hormonal changes are there to balance the body’s fatigue, tiredness, and hormones, few dietary recommendations are mentioned and it has been concluded that diet plays an important role during pregnancy, and meeting all the nutrition needs is an essential factor in planning the diet. Many diseases/deficiencies are there such as goiter, iodine deficiency, folate deficiency, gestational diabetes mellitus, gestational weight gain, Neural tube defects, and much more. A detailed view is mentioned below in the following paper: On average, pregnancy lasts 40 to 42 weeks (Nine months). On average, weight gain for a pregnant woman is 12 to 14 kg, thus weight gain can lower the risk of complications during labor and also lower the risk of LBW (low birth weight). Low GWG increases the risk of having an LBW infant. The average weight of the baby should be 2.5–3 kg. A baby having this much body weight should be considered a healthy infant. We provide up-to-date advice for achieving optimal nutrition before conception, throughout breastfeeding, in the first two years of life, and for preschoolers, with an eye on long-term health benefits. These guidelines are intended to aid in the primary prevention of obesity and the non-communicable diseases it is linked to among economically privileged groups, such as European women and children. Medical professionals should be incentivized and educated to promote and advise patients on preconception nutrition, which includes enhancing adolescent nutrition and health. Women who are physically active, eat healthily, don’t smoke, don’t drink excessively, and have a good body mass index (BMI) have a higher chance of having a safe pregnancy. Women of childbearing age should have their consumption and status of specific micronutrients closely monitored, especially folate. Women at risk for insufficient dietary intake of certain micronutrients may benefit from taking dietary supplements containing iron, vitamin D, vitamin B12, iodine, and maybe others. Smoke and alcohol should be strictly eliminated from the diet. Yes, diet plays an important role during pregnancy but staying physically active is equally important for the mother and the baby to promote general health and well-being. Exercise and stretching can reduce the risk of excessive maternal weight gain or gestational weight gain(Obesity). A long walk can greatly help a pregnant woman after lunch or in the morning.

Predictive model for dysmenorrhea level in female Taekwondo athletes: Investigating the influence of BMI and micronutrient intake

Disturbances during menstruation such as dysmenorrhea affect the performance of female athletes. However, research on the physiologic conditions of female Taekwondo athletes was still very limited. This study aimed to obtain a predictive model for the level of dysmenorrhea and to test which variable had the most influence on the rate of dysmenorrhea. The research design adopted cross-sectional methods. Multiple linear regression analysis was performed to analyze the effect of BMI and micronutrient intake of nine elite regional and national female Taekwondo. The results showed that the average female athlete had a normal BMI, while for micronutrient intake per day, the average intake of vitamin E was low, the vitamin B6 intake was low, Magnesium intake was low and Calcium intake was fulfilled. The most influence on the occurrence of primary dysmenorrhea in female Taekwondo athletes was calcium intake. This study was limited to measurements of BMI and dietary micronutrient intake, which might help provide data that coaches, athlete nutritionists, and athletes could be used to predict and assess the incidence of primary dysmenorrhea. More research could use the Food Frequency Questionnaire (FFQ), which could better explain how often athletes consumed certain food ingredients over a specific time period.

Determination of Nutritional Status in Children with Cystic Fibrosis

Cystic fibrosis is a disease that affects quality of life and life span as a result of mutation in the transmembrane conductivity regulator gene. The aim of this study is to determine the nutritional status of 2–18-year-old children with cystic fibrosis.75 children with cystic fibrosis between the ages of 2-18 were included in the study. The data were obtained online with the "Sociodemographic Form", "Nutrition Evaluation Form" and "24-Hour Food Consumption Record". Dietary quality, energy intake, macro and micronutrient intakes of the participants were determined by taking a 24-hour food consumption record. IBM Statistical Package for Social Sciences Version 24 statistical program and BEBIS 8.2 program were used to analyze the data obtained through the questionnaire.&#x0D; In this study 32 girls and 43 boys were included. It was determined that the daily energy intake of the girls was 1368 ± 394 kcal, and the boys were 1496 ± 494 kcal. When the z-score values of the participants are examined, the z-score value according to the height is minimum -4.16, maximum 3.05; It has been determined that the z-score value for weight is minimum -3.79 and maximum 2.60. The mean z-score of the participants for height was -0.25; The mean z score according to weight was determined as -0.40. The average weight of the boys is 30 kg, and the girls are 28.4 kg. More studies are needed to determine nutritional status, new nutritional therapies, and supplemental doses in children with cystic fibrosis.

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.

Dietary intake of macro and micronutrients correspond with sleep behaviors in collegiate female soccer players

Both macro and micronutrient intakes have an impact on sleep behaviors in athletes, notably sleep onset latency and sleep efficiency. Proper nutrient intake supports daily muscle repair and synthesis of sleep regulating compounds (e.g., serotonin and melatonin). The objective of this study was to evaluate the relationship between sleep behaviors and dietary intake in elite college female athletes. It was hypothesized that dietary carbohydrates and vitamin intake would be associated with both sleep timing and consistency. Twenty-three female Division I collegiate soccer players were evaluated for their sleep and nutritional patterns. Athletes wore an OURA ring (OURA Health, Oulu, Finland) each night for 31 days during the competitive season. During the final three days, athletes recorded their dietary intake using the Automated Self-Administered 24-hour Dietary Assessment Tool (ASA24). All athletes were exposed to the same travel schedule throughout the evaluation period, which did not differ by more than one time zone. Pearson’s R with Bonferonni Correction was used to assess the relationship between the average daily intake of various nutrients with average nightly sleep behaviors. Total Vitamin B12 ( r=-0.63), added Vitamin B12 ( r=-0.62), and Vitamin C ( r=-0.53) were negatively correlated with average bedtimes (P&lt;0.01) while added Vitamin B12 ( r=-0.61) and Vitamin C ( r=-0.50) were also negatively associated with wake times (P&lt;0.01). Greater dietary intake of kcals from carbohydrates, with respect to recommended consumption, was associated with earlier bedtimes ( r=0.41, P&lt;0.05). In conclusion, greater intake of carbohydrates and vitamins B12 and C are associated with ideal sleep behaviors. A potential mechanism accounting for this relationship could be the enhanced contribution of antioxidants and glycemic load on the synthesis of vital hormones for sleep regulation, including serotonin and melatonin.

Dietary intake of micronutrients are predictor of premenstrual syndrome, a machine learning method

Background & Aims Premenstrual syndrome (PMS) is a common disorder affecting 30-40% of women of reproductive age. Many of the modifiable risk factors associated with PMS involve nutrition and poor eating habits. This study aims to explore the correlation between micronutrients and PMS in a group of Iranian women and to build a predictor model showing the PMS using nutritional and anthropometric variables. Methods This is a cross-sectional which was conducted on 223 females in Iran. Anthropometric indices including Body Mass Index (BMI) and skinfold thicknesses were measured. For assessing the dietary intakes of participants, Food Frequency Questionnaire (FFQ) and for analyzing the data, machine learning methods were used. Results After applying different variable selection techniques, we’ve created machine learning models such as KNN. KNN achieved 80.3% accuracy rate and 76.3% F1 score indicating that our model is a curate and valid proof to show a strong relationship between input variables (sodium intake, Skin fold thickness of suprailiac, irregular menstruation, total calorie intake, total fiber intake, trans fatty acids, painful menstruation (dysmenorrhea), total sugar intake, total fat intake, and biotin) and the output variable (PMS). We sorted these effective variables based on their ‘Shapley values’ and we figured out Na intake, suprailiac skinfold thickness, biotin intake, total fat intake and total sugar intake have major impact on having PMS. Conclusions Dietary intakes and anthropometric measurements are highly associated with occurrence of PMS and in our model these variables can predict PMS in women with a high accuracy rate.

KNN achieved 80.3% accuracy rate and 76.3% F1 score indicating that our model is a curate and valid proof to show a strong relationship between input variables (sodium intake, Skin fold thickness of suprailiac, irregular menstruation, total calorie intake, total fiber intake, trans fatty acids, painful menstruation (dysmenorrhea), total sugar intake, total fat intake, and biotin) and the output variable (PMS). We sorted these effective variables based on their ‘Shapley values’ and we figured out Na intake, suprailiac skinfold thickness, biotin intake, total fat intake and total sugar intake have major impact on having PMS. Dietary intakes and anthropometric measurements are highly associated with occurrence of PMS and in our model these variables can predict PMS in women with a high accuracy rate.
