Effect of Ramadan Fasting on Breast Milk.

Introduction: Breast milk is an excellent biofluid that ensures optimal growth, development, and strong immunity of the baby. Breast milk content may alter depending on duration and time of breastfeeding, the infant's age, and maternal health status. There are few studies in the literature investigating the effect of religious fasting on breast milk composition. Method: The study included 21 fasting and 27 nonfasting mothers who exclusively breastfed their babies in 2021 Ramadan month. The energy, carbohydrate, protein, and lipid levels of the collected breast milk samples and the macro- and micronutrient contents of the mothers' diets and the weight gain of the infants during the study were evaluated. Results: The mothers' ages, education levels, and weights at birth and at the time of sampling were similar. There was no significant difference between the energy, carbohydrate, protein, and lipid composition of breast milk in fasting and nonfasting mothers. Although daily energy, protein, carbohydrate, fiber, and vitamin intakes between two groups were similar, mean daily intake of lipid, sodium, chloride, iodine, and omega-3 fatty acids was determined significantly higher in study group. Also, there was no difference in the weight gain of babies during the month of Ramadan. Conclusion: Religious fasting of mothers does not affect the energy and macronutrient content of breast milk. In addition, fasting does not seem to affect the weight of mothers and babies.

Do macronutrient intakes affect obesity indices in Jordanian adults?

To determine whether macronutrient intake is associated with novel obesity indices, including the conicity index (CI), body adiposity index (BAI), abdominal volume index (AVI), body roundness index (BRI), and weight-adjusted-waist index (WWI). A cross-sectional survey was conducted with 491 adults (344 males and 147 females) working at different universities in Jordan (July-December 2019). Daily intake of energy (kcal), carbohydrates (g), protein (g), and fat (g) was obtained using 24-h recalls collected over 2 days. Additionally, obesity indices were calculated. Regardless of sex, energy, and carbohydrate intakes had a moderately significant positive association, whereas protein and fat intakes had a weakly significant association with BAI, AVI, and BRI. CI and WWI showed a weakly significant association with all macronutrients in males, a moderate correlation with energy and carbohydrate intake, and a weak association with fat and protein intake in females. Male participants had significant increases in the CI (T1 = 1.29 ± 0.01 vs. T3 = 1.36 ± 0.01, p = .018), AVI (T1 = 17.96 ± 0.52 vs. T3 = 22.81 ± 0.57, p = .011), and WWI (T1 = 10.72 ± 0.11 vs. T3 = 11.29 ± 0.09, p = .047) indices scores through the carbohydrate intake tertiles. Additionally, there was a significant increase in scores of AVI (T1 = 18.60 ± 0.56 vs. T3 = 21.42 ± 0.46, p = .048) and an almost significant increase in CI (T1 = 1.30 ± 0.01vs. T3 = 1.33 ± 0.01, p = .056) through the tertiles of protein intake. Macronutrients were significantly associated with all indices. The effect of macronutrients on obesity indices is sex-based. Among men, CI, AVI, and WWI were the indices most affected by carbohydrate and protein intakes. Future studies should further investigate food sources and macronutrient quality.

Case report on nutrition management in liver transplant

Liver transplantation or hepatic transplantation is a procedure of replacing diseased liver with a healthy liver. It needs cautious post-operative care including nutritional intervention. We present a 65 year old patient underwent a liver transplant due to acute liver failure. The patient’s diet history revealed a daily intake of carbohydrates and fats but inadequate protein intake. The patient’s nutritional interventions were analyzed and evaluated through hospital recalls and proper follow up visits. In studies, hospital recall on 7 day of post-surgery showed a great improvement in calorie and protein intake. The discharge diet plan included a well-balanced diet with protein, carbohydrates and fat intake to ensure nutritional care for the patient’s recovery. Nutritional intervention plays a vital role in post-operative care of liver transplant patients. This case study signifies the importance of personalized dietary intervention to resolve PEM, improve nutritional intake while supporting successful surgical outcome and recovery .

Status of dietary energy and consumption of food among Chinese diabetics aged 45 years and above in 2015

To investigate the macronutrient and food intake of diabetics aged 45 years and above in China. The research data was based on the China Adult Chronic Disease and Nutrition Surveillance in 2015. The dietary nutrition status of diabetics living in community was investigated by questionnaire, condiments weighing and 3 days-24 hours dietary questionnaire. Assessment was compared with the recommended amount of macronutrient energy supply ratio in The guideline for the prevention and treatment of type 2 diabetes mellitus in China(2020 edition). The macronutrient energy supply ratio of patients with different types of diabetes was evaluated and their food intake was statistically analyzed. The median of daily intake of total energy, protein, fat and carbohydrate were 1585 kcal, 50.1 g, 62.4 g and 200.1 g, respectively. The energy ratios of protein, fat and carbohydrate were 12.6%, 36.3% and 52.1%, respectively. In diabetics, the proportion of protein, fat and carbohydrate energy ratios that meet the recommendations in The guideline for the prevention and treatment of type 2 diabetes mellitus in China(2020 edition) were 20.5%, 21.7% and 40.4%, respectively. There is an unreasonable macronutrient energy ratio in the diet of diabetic over 45 years old in China, which mainly shows that the proportion of protein energy supply ratio in most diabetics is low, and the proportion of fat energy ratio exceeds the standard is high.

24-h glucose level and variability in response to carbohydrate overfeeding assessed using continuous glucose monitoring system are associated with daily carbohydrate intake

The quantity gap between daily and loaded carbohydrates may affects blood glucose response to carbohydrate intake; however, no study has investigated the difference in 24-h span. This study aimed to determine differences in the 24-h glucose levels and variability in response to single-day carbohydrate overfeeding based on daily carbohydrate intake in healthy Japanese men. Twenty male college students completed a 3-day dietary record and were divided into two groups based on whether their daily carbohydrate intake exceeded the median intake (H-CHO) or not (L-CHO). Thereafter, the participants consumed a high-carbohydrate diet (carbohydrate 8.1g/kg/d) for 1 day. The 24-h glucose levels and glucose variability (CONGA1) were measured using a continuous glucose monitoring system. The mean daily carbohydrate intakes in the L-CHO and H-CHO groups were 3.9±0.5 and 5.8±0.6g/kg/d, respectively (p<0.001). The peak 24-h glucose level was not differ between the L-CHO group and the H-CHO group (8.0±0.8 vs. 8.0±1.0; p=0.886). The mean 24-h glucose level was higher in the L-CHO group than in the H-CHO group (6.0±0.3 vs. 5.6±0.3mmol/L; p=0.010). The CONGA1 was higher in the L-CHO group than in the H-CHO group (5.40±0.41 vs. 4.95±0.25; p=0.008). Mean glucose level and glucose variability in response to carbohydrate overfeeding were high in the individuals with small daily carbohydrate intake. These findings suggest that the large quantity gap between daily and loaded carbohydrates cause worse glucose control during carbohydrate overfeeding.

Comparison of skin carotenoid content scores and dietary intake between cognitively normal older adults and older adults with Alzheimer’s Disease: A matched‐pair analysis

AbstractBackgroundAlzheimer’s Disease (AD) is a systemic metabolic disease with a variable number and type of clinical symptoms mostly impacting the brain. Skin carotenoid content (SCC) is an objective measure of carotenoid‐containing fruit and vegetable intake that has been validated in diverse populations. Our previous findings suggest SCC scores are impacted by various metabolic disease states. Therefore, our objective was to analyze SCC scores and dietary intake across matched pairs including unimpaired adults and those with AD.MethodBaseline data from two dietary interventions (NCT03860792, NCT03841539) were analyzed. Pairs are exact matches for sex, race/ethnicity, and education and are matched within two years of age and 4 kg/m2 body mass index. Each pair (n = 12 pairs) includes one cognitively normal (MMSE &gt; 25), community dwelling older adult (‘CN’) and one community dwelling older adult with AD (‘AD’). Baseline self‐reported dietary intake data (3‐day food records) were collected, reviewed, and entered into the Nutrition Data System for Research (NDSR 2019) database by a Registered Dietitian. SCC scores were collected through pressure‐mediated reflection spectroscopy via VeggieMeter® (Longevity Link Corporation, Holladay, UT). Two‐sample independent t‐tests assuming unequal variances were used to compare differences in SCC scores and dietary intake. Significance was set at p = 0.05.ResultThere was a significant difference in SCC scores between matched pairs (SCC scores: CN 284.25, AD 207.67, p = 0.008). There was no difference between pairs for total daily energy (kcal/day; p = 0.60), fat (g/day; p = 0.91), carbohydrate (g/day; p = 0.85), or protein (g/day; p = 0.26) intake. Both groups had similar food group intake (p‐value range 0.09‐0.79), including all fruit and vegetable groups except CN had higher intake of non‐citrus fruit (p = 0.046). Total fruit (p = 0.09) and fruit plus vegetable (p = 0.24) were not different between pairs. Dietary intake by individual carotenoid was not significantly different (total vitamin A, p = 0.48; beta‐carotene, p = 0.49; alpha‐carotene, p = 0.57; beta‐cryptoxanthin, p = 0.60; lutein plus zeaxanthin, p = 0.07; lycopene, p = 0.37).ConclusionIndividuals with AD have lower carotenoid skin content compared to matched cognitively unimpaired individuals. These differences are not explained by differences in diet suggesting that AD may be associated with disease‐associated biochemical features that are metabolism‐related and not limited to the brain.

Impact of a Low-Carbohydrate Compared with Low-Fat Breakfast on Blood Glucose Control in Type 2 Diabetes: A Randomized Trial

BackgroundIn type 2 diabetes (T2D), consuming carbohydrates results in a rapid and large increase in blood glucose, particularly in the morning when glucose intolerance is highest. ObjectivesWe investigated if a low-carbohydrate (LC) breakfast (∼465 kcal: 25 g protein, 8 g carbohydrates, and 37 g fat) could improve glucose control in people with T2D when compared with a low-fat control (CTL) breakfast (∼450 kcal:20 g protein, 56 g carbohydrates, and 15 g fat). MethodsParticipants with T2D (N = 121, 53% women, mean age 64 y) completed a remote 3-month parallel-group randomized controlled trial comparing a LC with standard low-fat guideline CTL breakfast. The change in HbA1c was the prespecified primary outcome. Continuous glucose monitoring, self-reported anthropometrics, and dietary information were collected for an intention-to-treat analysis. ResultsHbA1c was reduced (−0.3%; 95% CI: −0.4%, −0.1%) after 12 wks of a LC breakfast, but the between-group difference in HbA1c was of borderline statistical significance (−0.2; 95% CI: −0.4, 0.0; P = 0.06). Self-reported total daily energy (−242 kcal; 95% CI: −460, −24 kcal; P = 0.03) and carbohydrate (−73 g; 95% CI: −101, −44 g; P < 0.01) intake were lower in the LC group but the significance of this difference is unclear. Mean and maximum glucose, area under the curve, glycemic variability, standard deviation, and time above range were all significantly lower, and time in the range was significantly higher, in the LC group compared with CTL (all P < 0.05). ConclusionsAdvice and guidance to consume a LC breakfast appears to be a simple dietary strategy to reduce overall energy and carbohydrate intake and improve several continuous glucose monitoring variables when compared with a CTL breakfast in persons living with T2D.The trial was registered at clinicaltrials.gov as NCT04550468.

Pen-administered low-dose dasiglucagon vs usual care for prevention and treatment of non-severe hypoglycaemia in people with type 1 diabetes during free-living conditions: a Phase II, randomised, open-label, two-period crossover trial

Aims/hypothesisConsumption of excess carbohydrates to manage hypoglycaemia can lead to rebound hyperglycaemia and promote weight gain. The objective of this trial was to evaluate the efficacy, safety and feasibility of pen-administered low-dose dasiglucagon for prevention and treatment of non-severe hypoglycaemia in people with type 1 diabetes during free-living conditions.MethodsTwenty-four adults with insulin pump-treated type 1 diabetes (HbA1c ≤70 mmol/mol [8.5%]) completed a randomised, open-label, two-period crossover study with 2 week periods. During the usual care and dasiglucagon intervention (DASI) periods, participants managed impending and manifested episodes of hypoglycaemia with regular carbohydrate consumption or pen-administered low-dose (80 μg) s.c. dasiglucagon, respectively. Glycaemic control was evaluated using continuous glucose monitoring (Dexcom G6) and event registration of prevention and treatment episodes.ResultsCompared with usual care, the mean difference (95% CI) in the DASI period for time in (3.9–10.0 mmol/l) and below (<3.9 mmol/l) range was 2.4 %-points (−0.7, 5.5) and −0.5 %-points (−1.2, 0.2), respectively. In the DASI period, recovery rate (time from hypoglycaemia treatment to euglycaemia) was 44% (11, 87) faster while total daily carbohydrate intake was reduced by 11% (−18, −3). Dasiglucagon use was safe and well tolerated with mild nausea being the most frequent adverse effect. Among the participants, 96% (p<0.0001) were likely to include dasiglucagon in their future routine management of hypoglycaemia.Conclusions/interpretationUse of low-dose dasiglucagon to prevent and treat non-severe hypoglycaemia during free-living conditions was safe, fast and efficacious while significantly reducing the total daily carbohydrate intake and yielding high treatment satisfaction.Trial registrationClinicalTrials.gov NCT04764968FundingThe study was an investigator-initiated trial. Zealand Pharma supplied the investigational drug and device and provided financial support for the conduct of the trial.Graphical abstract

Nutrition status and diet quality in healthcare professionals with different chronotypes: a comparative study

ABSTRACT This study aimed to examine the nutritional status of healthcare professionals with different chronotypes and to determine their diet quality. Of the health care professionals (n = 204), 10.3% were morning chronotype (n = 21), 14.2% were evening chronotype (n = 29) and 75.5% were intermediate chronotype profiles (n = 154). Daily carbohydrate intake was significantly higher in the evening chronotype participants than was that in the morning and intermediate chronotype participants (p < 0.05). Daily intake of total fat, saturated fat, monounsaturated fatty acid (MUFA), and sodium in all the participants was above the population-specific recommended values, and saturated fat intake was highest in the evening chronotype participants. Nutritional status (except carbohydrate and potassium) and diet quality of healthcare professionals participating in the present study did not differ according to their chronotypes. Their diet quality was not good and their energy and nutrient intakes were below the requirements.

Assessment of dietary consumption in a group of pregnant women at their second and third trimesters in Amman

Background: For a child's healthy growth and development, nutrition is indispensable before and during pregnancy. Meeting nutritional needs during pregnancy has always been a significant public health issue. Objective: The study aimed to assess and evaluate energy, macronutrients, and micronutrient consumption from food among pregnant women in Amman Governorate during the second or third trimesters, then compare the consumption to the Recommended Dietary Allowance (RDA). In addition, it aimed to assess micronutrient consumption from foods and supplements; finally, it investigated macronutrient consumption among under-weight, normal-weight, overweight, and obese pregnant women. Methods: A cross-sectional study was carried out in 2018 at the Ministry of Health's (MoH) Maternal and Children Health Centers (MCHC) in Amman to assess the dietary intake in a convenient sample of 300 seemingly healthy pregnant women between 17 and 40 years old and at ≥ 13 weeks of gestation. Maternal demographic characteristics, medical history, anthropometric measurements, and dietary data (three-day recall) were collected. Results: The daily mean intake of carbohydrates exceeded the recommended intake in 45.3% of pregnant women. Fiber intake was less than 28g/day in 90% of them. Total fats intake (45.6g/day) was lower than the RDA in 42.3% of pregnant women. Two-thirds of the pregnant women consumed a moderate amount of saturated fats (14.6g/day). The mean daily intake of proteins was 50.5±20.2g—more than two-thirds consumed protein less than the RDA. Subsequently, intakes of all essential amino acids were below RDAs.The intake of fat-soluble vitamins was lower than RDA for vitamins D, E, and K.While, whereas vitamin A was higher than RDA. Copper and salt intakes were more significant than the RDA for minerals (calcium, fluoride, iodine, iron, zinc, and selenium). Conclusion: The results showed inadequate and imbalanced dietary intake compared to RDA. Maternal nutrition and diets of pregnant women in this study show alarming indicators that may negatively affect the well-being of both pregnant women and fetal growth.

Does mindful eating affect the diet quality of adults?

ObjectivesThis study aimed to examine the relationship between mindful eating and diet quality among adults in Turkey. MethodsA total of 207 adults, 138 women (66.7% of 207) and 69 men (33.3%), participated. This cross-sectional survey was carried out among adults aged 20–50 y. The following data were collected from face-to-face interviews: sociodemographic variables, health information, nutritional habits, anthropometric measurements, 24-h dietary records, and scores from the Mindful Eating Questionnaire (MEQ), Mediterranean Diet Adherence Screener (MEDAS), and Healthy Eating Index-2015 (HEI-2015). ResultsThe mean MEDAS scores of females were higher than those of males (P = 0.012). The mean HEI-2015 scores did not significantly differ between females and males (P > 0.05). The mean scores of the MEQ (P = 0.024) and its disinhibition (P = 0.005) and emotional eating (P = 0.000) subfactors were higher in males than in females. The MEQ mean score was negatively associated with daily energy (P = 0.038), carbohydrate (P = 0.046), and fat intake (P = 0.036). As the MEQ mean score increased, the greens and beans score (P = 0.009) and dairy intake score (P = 0.031) increased. A positive correlation was present between the eating discipline subfactor of the MEQ score and both the HEI-2015 (P = 0.002) and MEDAS mean scores (P = 0.001). However, no significant correlation was found between the mean MEQ and HEI-2015 scores and the MEDAS mean scores (P > 0.05). ConclusionsDeveloping mindful eating might be helpful for individual health promotion and quality of life by providing improvements in diet quality of adults.

Nutrition Recommendations for Table Tennis Players-A Narrative Review.

Table tennis (TT) is the second most popular racket sport globally and was the sixth most widely played Olympic sport in 2005. It is an indoor racket sport requiring a mixture of power, agility, alertness and fast reactions. Players need to move quickly around a table to receive the ball and produce powerful returns. New rules such as increased ball size and a change in ball material have changed the ball's trajectory, increasing the overall duration and intensity of game play. Scientific research on TT is growing but there has been no systematic review of nutrition for the sport. This review provides nutritional recommendations for TT athletes based on the physiological demands of TT, including energy expenditure during training and competitions, and the main metabolic pathways of TT. Guidelines on the daily intakes of carbohydrate, protein and fat are discussed in addition to hydration strategies. Micronutrients of concern for TT athletes include iron, magnesium and vitamin D and their recommended intakes are also provided. The timing and dose of ergogenic aids that may improve TT performance such as caffeine, creatine, lutein and zeaxanthin and beta-alanine are reviewed. Specific nutritional strategies for intakes leading up to competitions, post training and competition recovery and nutritional strategies for travel are also addressed.

Composition of Common Junk Food Items and Their Contribution to the Dietary Requirement of Children and Adolescents

To estimate the carbohydrate, energy, fat, protein, and sodium content of commonly consumed junk food items and to compare these to the Recommended Dietary Allowance (RDA) and Estimated Average Requirements (EAR) of children. A list of eight common junk food categories was made, and the median nutritional content of carbohydrate, energy, fat, protein and sodium was determined from the commonly consumed brands in these categories. It was compared to the RDA and EAR for two different age groups viz., age 4-6 year, and male adolescents aged 13-15 years. The junk food groups with the highest carbo-hydrate were packaged potato chips and cakes, the group with the highest fat content was packaged potato chips, and the groups with the highest salt content were burgers and packaged potato chips. The %EAR of one packet of some items was 80-90% of daily fat requirement, and more than 60% of daily sodium requirement. Junk foods contribute substantially to the daily intake of carbohydrates, free sugars, total fats, saturated fats, and sodium of children.

Significant Changes in Resting Metabolic Rate Over a Competitive Match Week Are Accompanied by an Absence of Nutritional Periodization in Male Professional Soccer Players.

Resting metabolic rate (RMR) is an important component of total daily energy expenditure; however, it is currently not understood how it varies across a typical competitive match week in professional soccer players. For the first time, we aimed to assess RMR throughout an in-season competitive week in professional soccer players. Additionally, we aimed to assess energy and carbohydrate intake across the same week. Twenty-four professional soccer players from an English Premier League club (age: 18 ± 1.6years) completed the study. RMR was assessed each morning of a typical competitive match week (match day [MD] -3, -2, -1, +1, +2, and + 3), and dietary intake (including MD) was assessed daily via the remote food photography method and 24-hr recall. Daily training load was quantified using Global Positioning System, daily muscle soreness ratings were recorded, and body composition was assessed via dual-energy X-ray absorptiometry. There was a significant (p = .0004) increase in mean RMR of ∼261kcal/day on MD + 1, compared with MD - 1. Additionally, volume of oxygen consumed significantly increased at MD + 1 (p = .0002) versus MD - 1. There were no significant differences in daily energy or carbohydrate intake across the competitive week (p > .05), with inadequate carbohydrate intakes on MD - 1 (∼3.9g/kg body mass), MD (∼4.2g/kg body mass), and MD + 1 (∼3.6g/kg body mass) in relation to current recommendations. We report, for the first time, that RMR is significantly increased following a competitive match in professional soccer players. In addition, we confirm previous findings to reinforce that players exhibit inadequate nutrition periodization practices, which may impair physical performance and recovery.

Relationship between intra-individual variability in nutrition-related lifestyle behaviors and blood glucose outcomes under free-living conditions in adults without type 2 diabetes

AimsThis study determined the relationship between intra-individual variability in day-to-day nutrition-related lifestyle behaviors (meal timing, eating window, food intake, movement behaviors, sleep conditions, and body weight) and glycemic outcomes under free-living conditions in adults without type 2 diabetes. MethodsWe analyzed 104 adults without type 2 diabetes. During the 7-day measurement period, dietary intake, movement behaviors, sleep conditions, and glucose outcomes were assessed. Daily food intake was assessed using a mobile-based health application. Movement behaviors and sleep conditions were assessed using a tri-axial accelerometer. Meal timing was assessed from the participant’s daily life record. Blood glucose levels were measured continuously using a glucose monitor. Statistical analyses were conducted using a linear mixed-effects model, with mealtime, food intake, body weight, movement behaviors, and sleep conditions as fixed effects and participants as a random effect. ResultsDinner time and eating window were positively significantly correlated with mean (dinner time, p = 0.003; eating window, p = 0.001), standard deviation (SD; both at p < 0.001), and maximum (both at p < 0.001) blood glucose levels. Breakfast time was negatively associated with glucose outcomes (p < 0.01). Sedentary time was positively significantly associated with blood glucose SD (p = 0.040). Total sleep time was negatively significantly correlated with SD (p = 0.035) and maximum (p = 0.032) blood glucose levels. Total daily energy intake (p = 0.001), carbohydrate intake (p < 0.001), and body weight (p < 0.05) were positively associated with mean blood glucose levels. ConclusionIntra-individual variations in nutrition-related lifestyle behaviors, especially morning and evening body weight, and food intake, were associated with mean blood glucose levels, and a long sedentary time and total sleep time were associated with glucose variability. Earlier dinner times and shorter eating windows per day resulted in better glucose control.

Halting the Metabolic Complications of Antipsychotic Medication in Patients with a First Episode of Psychosis: How Far Can We Go with the Mediterranean Diet? A Pilot Study

Patients with first-episode psychosis (FEP) often adopt unhealthy dietary patterns, with a risk of weight gain and metabolic and cardiovascular disease. In 21 FEP patients receiving nutritional intervention based on the Mediterranean diet (MedDiet), we explored differences in anthropometric and biometric parameters, according to their antipsychotic (AP) medication: AP1, associated with a lower risk, or AP2, associated with a higher risk of weight gain and metabolic complications. The blood biochemical profile was recorded before and after dietary intervention, and dietary habits and body composition were monitored for six months. Following intervention, all of the patients recorded significant increases in the consumption of fruit and vegetables and decreases in red meat and poultry consumption, with closer adherence to the MedDiet and a reduction in the daily intake of calories, carbohydrates, and sodium. Vegetable consumption and energy, protein, and carbohydrate intake were lower in AP1 patients than in AP2 patients. There was no significant weight gain overall. A reduction was demonstrated in total and LDL cholesterol, sodium, urea, and iron (lower in AP1 patients). It was evident that AP medication affected blood levels of lipids, urea, and iron of FEP patients, but MedDiet nutritional intervention led to a significant improvement in their eating habits, with a restriction in weight gain and a decrease in blood sodium and urea.

Nutritional Practices and Body Composition of South African National-Level Spinal Cord-Injured Endurance Hand Cyclists.

Nutritional practices and body composition of para-athletes can impact their health and athletic performance. There is a paucity of research on the nutritional practices, including dietary and supplement intake, body composition and bone health of spinal cord-injured (SCI) endurance hand cyclists. This study assessed the body composition and dietary and supplement intake of 12 national-level SCI endurance hand cyclists (age: 44.0 ± 9.3 years). Bone mineral density (BMD) was assessed in a sub-sample of participants (n = 4) using dual-energy x-ray absorptiometry (DXA). Estimated body fat percentage was healthy (18.4 ± 5.1%) and lumbar spine BMD for the sub-sample was adequate, however hip BMD was low (Z-score and/or T-scores < −2). Carbohydrate intake for male and female participants was below the recommended intake (3.8 (2.9−4.1) and 2.4 (2.0−2.7) g/kg BW, respectively). Overall protein intake was adequate, whilst fat intake was high for both males and females (39.7 (37.7−41.6) and 42.1 (39.0−45.3)% of total energy, respectively). The reported intakes for a few key micronutrients were also below the recommended dietary allowance (RDA) and/or adequate intake (AI) for males (vitamin D, calcium). The prevalence of supplement use before, during, and after training was 40%, 100%, and 60%, respectively. In conclusion, the hand cyclists could benefit from nutritional guidance to match their daily carbohydrate intake with exercise requirements and optimise their fat intake. Optimal vitamin D and calcium intake is also important especially in the light of poor bone health below the lesion level.

Association of nutrition knowledge, practice, supplement use, and nutrient intake with strength performance among Taekwondo players in Nepal.

Optimum dietary intake and adequate nutritional knowledge have been recognized as the key factors that play a critical role in improving the athlete's health and nutrition status. This study aimed to measure the association of nutritional knowledge, practice, supplement use, and nutrient intake with strength performance among Nepalese Taekwondo players. Between August 2019 and January 2020, a cross-sectional study was conducted among 293 Taekwondo players in Kathmandu Metropolitan City (mean age, 18 years; 63.1% male, 36.9% female). Face-to-face interviews were conducted using semi-structured questionnaires. Anthropometric measures, nutritional intake, nutrition knowledge, and practice were all recorded. The handgrip strength was measured using a handgrip dynamometer as a proxy for strength performance. Univariate and bivariate analyses were used to find out the association between predictor and outcome variables. More than half of the participants had poor nutrition knowledge [54.3% (159/293)], and poor nutrition practice [55.3% (162/293)] scores. Daily mean energy, carbohydrate, protein and fat intake were 48.0 kcal.kg-1.d-1, 8.6, 1.6, and 1.5 g.kg-1.d-1, respectively among Taekwondo players. Daily total energy and carbohydrate intake were 48.2 kcal.kg-1.d-1 and 8.7 g.kg-1.d-1, respectively among male players which is higher than female players. However, daily protein and fat intake were higher in female players (1.7 and 1.6 g.kg-1.d-1, respectively). Both calcium (375.3 mg) and iron (9 mg) intake among Taekwondo players were significantly lower than current sports nutrition guidelines. Nutritional knowledge score (r = 0.117), height (r = 0.538), weight (r = 0.651), body mass index (r = 0.347), fat (r = 0.075), and energy (r = 0.127) intake showed significant positive correlation with strength performance of athletes. The strength performance was positively associated with training hours per day (β = 0.41, 95% CI: 0.09-0.91), body mass index (β = 0.35, 95% CI: 0.09-0.61), nutrition knowledge score (β = 0.13, 95% CI: 0.01-0.25), and energy intake (β = 0.13, 95% CI: 0.12-0.14). The nutritional knowledge and practice both were suboptimal among Taekwondo athletes. Height, weight, body mass index, nutritional knowledge, energy, and fat intake showed a positive correlation with strength performance. Future studies can build on the premise of this study to identify the robust relationship between nutritional knowledge, practice, different supplement use, and nutrient intake among other athletes too.

Attention Action Needs to be Taken in Regard to the Dietary Intake of Pregnant Women in Amman

Background: pregnancy, RDA, nutrients intake, malnutrition, the second half of pregnancy, macronutrients, micronutrients, public health issue, maternal nutrition. Objective: The study aimed to assess and evaluate energy and nutrients consumption among a group of pregnant women in Amman Governorate during the second or third trimesters; in order to compare the consumption with “Recommended Dietary Allowance” (RDA). Methods: A cross-sectional study was carried out in 2018 at the Ministry of Health’s (MoH) Maternal and Children Health Centers (MCHC) in Amman to assess the dietary intake for a convenient sample of 300 seemingly healthy pregnant women aged between 17 and 40 years-old and at ≥ 13 weeks of gestation. Maternal demographic cheracteristics, medical history, anthropometric measurements and dietary data (three days recall) were collected. Results: The daily mean intake of carbohydrates exceeded the recommended intake for 45.3% of pregnant women. Fiber intake was less than 28 g/day for 90% of them. Total fats intake (45.6 g/- day) was lower than the RDA for 42.3% of the pregnant women. Two-thirds of the pregnant women consumed a moderate amount of saturated fats (14.6 g/day). The mean daily intake of proteins was 50.5±20.2g. More than two-thirds consumed protein less than the RDA; subsequently, intakes of all essential amino acids were below RDAs. The intake of fat-soluble vitamins was lower than RDA for vitamins D, E, and K.While, the intake of vitamin A, was higher than RDA. The intake of minerals was lower than RDA for (calcium, fluoride, iodine, iron, zinc, and selenium), while the intakes of sodium and copper were higher. Conclusion: The results showed inadequate and imbalanced dietary intake in comparison with RDA. Maternal nutrition and diets of pregnant women in this study show alarming indicators that may negatively affect the well-being of both pregnant women and fetal growth.
