Influence of Fruit and Vegetable Consumption on Antioxidant Status and Semen Quality: A Cross-Sectional Study in Adult Men.

The influence of fruit and vegetable consumption on semen quality by reducing oxidative stress is inconsistent. Thus, the association between the consumption of these products, antioxidant status, and semen quality was investigated in 90 men aged 18–40. The consumption of fruit and vegetables was collected using the 3-day food record method. Antioxidant status: total antioxidant capacity in semen (TAC-s) and blood (TAC-b), blood superoxide dismutase (SOD-b), glutathione reductase (GR-b), glutathione peroxidase (GPx-b), catalase (CAT-b) activity, and malondialdehyde concentration in blood (MDA-b) were measured. Sperm concentration, leukocytes in the ejaculate, vitality, motility, and sperm morphology were examined using computer-aided semen analysis (CASA). The consumption of fruit and vegetables was positively correlated with sperm concentration, vitality, motility, TAC-s, TAC-b, and SOD-b activity. The TAC-s and TAC-b were positively related to motility, TAC-s was inversely correlated with sperm tail defects. The SOD-b activity was positively correlated with vitality, motility, sperm morphology, and inversely with sperm tail defects and leukocytes in the ejaculate. Compared to the men in the first quartile of fruit and vegetable consumption (<318 g/day), those in the highest quartile (>734 g/day) had the highest sperm concentration, vitality, motility, TAC-s, TAC-b, GPx-b activity, and the lowest MDA-b concentration (based on multivariate regression models). A high consumption of fruit and vegetables may positively influence selected sperm quality parameters by improving the antioxidant status of semen and blood.

Physical activity and sedentary behaviors (screen time and homework) among overweight or obese adolescents: a cross-sectional observational study in Yazd, Iran

BackgroundThe growing number of adolescents who are overweight or obese (OW / OB) is a public concern. The present study was aimed to evaluate physical activity (PA) and sedentary behaviors (SB) (screen time (ST) and homework time (HT)) among Yazd OW/OB adolescents.MethodsThis cross-sectional study was performed among 510 students aged 12-16 in Yazd, Iran. The general information, PA, and SB (ST and HT) were collected by interview based on the WHO standard questionnaire. Anthropometric data were assessed by precise instruments. Daily energy intake (Energy) was obtained from a 7-day food record. Nutritionist 4 software (version I) was run to estimate the energy.ResultsThere was a high prevalence of SB > 2h/day (97.6), ST > 2h/day (70.3%), overweight or obesity (40%), abdominal obesity (36.9%), physical inactivity (29.8%) among the students. The younger age (p = 0.014), energy (p < 0.001), no access to the yard (p < 0.001), family size ≤ 2 (p = 0.023), passive transportation, (p = 0.001), the highest school days’ HT (p = 0.033) and SB (p = 0.021), and the highest weekends’ HT among the students were the risk factors for OW/OB. The highest PA level was associated with a lower risk of OW/OB (p < 0.001). The findings were not the same in both sexes. Compared to the normal weight students, OW / OB spent more time on school days and weekdays for ST (P <0.001), HT (P <0.001, P = 0.005) and SB (P <0.001), respectively. OW/OB students showed a higher weekends’ ST (p < 0.001) and lower HT (p = 0.048) than normal-weight students.ConclusionThe prevalence of SB, ST, OW/OB, and physical inactivity were common. The school days and weekends’ HT, the school days’ SB and HT, age, energy, PA, and access to the yard, family size, and passive transportation were related to the greater chances of OW/OB students. Given that the expansion of online education and self-isolation in a new situation with COVID-19, it seems we will meet the worrying results.

The potential role of plantains, moringa, plantain-moringa combined diets, and other plant-based dietary patterns in controlling glycaemia among T2DM persons, a hospital based cross sectional survey in Ghana.

Diabetes mellitus (DM) is an independent risk-factor for cardiovascular diseases. Plant-based dietary-patterns have been shown to reverse the effects of these cardiovascular risk-factors. Our study therefore aimed to investigate the potential roles moringa, moringa-plantain combined, and other plant based dietary-patterns could play in controlling glycaemia among persons with type-2-diabetes Mellitus (T2DM). Facility-based cross-sectional-study was conducted among 530 T2DM patients from August 2018 to September 2019 in Ghana. Structured-questionnaires were used to collect demographic, anthropometric, and clinical variables. Adherence to plant-based dietary-patterns were assessed using 3-day food record. SPSS version-20 was used to analyse the data. BMI, HbA1c%, HDL-cholesterol and LDL-cholesterol were significantly correlated with adherence to plant-based dietary-patterns (p-value < 0.05). After adjusting for physical activity, adherence to plantain diets Standardized regression coefficient β (95%CI): -0.098 (-0.321, -0.022), yam β (95%CI): 0.148 (0.066, 0.496), moringa diets β (95%CI): -0.095 (-0.325,-0.011) and bean-diets β (95%CI): -0.112 (-0.577, -0.007) were significantly associated with glycemic control. Adherence to plantain-moriga combined diets β (95%CI): -0.406 (-0.413, -0.049) and plantain-beans combined diets β (95%CI): -0.128 (-0.188, -0.038) were also significantly associated with glycemic control. Adherence to plantain, yam, beans, plantain-moriga combined diets, and plantain-beans combined diets could be associated with glycemic-control. Health care workers should prioritize these plant-based dietary-patterns for disease prevention and health promotion.

Relationship Between Dietary Phosphate Intake and Biomarkers of Bone and Mineral Metabolism in Australian Adults With Chronic Kidney Disease

Higher serum phosphate is associated with increased adverse outcomes including cardiovascular disease. Abnormalities of bone and mineral metabolism in chronic kidney disease (CKD), including higher serum phosphate, are important risk factors for increased cardiovascular disease. Associations between dietary phosphate intake and biochemical and cardiovascular parameters in non-dialysis CKD patients, however, have not been adequately studied. This study aimed to explore associations between phosphate intake and biomarkers of bone and mineral metabolism and intermediate cardiovascular markers in adults with stage 3-4 CKD. One hundred thirty-two participants enrolled in the IMpact of Phosphate Reduction On Vascular End-points in Chronic Kidney Disease trial were invited to participate in this sub-study. At baseline, dietary phosphate intake and its source (animal, plant, or a mixture of animal and plant) were determined using a 7-day self-administered diet food record, and measurements were made of serum and urinary phosphate, serum calcium, parathyroid hormone, fibroblast growth factor-23, and the intermediate cardiovascular markers pulse wave velocity (PWV) and abdominal aortic calcification. The relationships between dietary phosphate intake and these bone metabolism and cardiovascular markers were explored using Pearson's correlation and linear regression. The effect of source of phosphate intake was analyzed using compositional data analysis. Ninety participants (age 64±12years, 68% male, estimated glomerular filtration rate 26.6±7.6mL/min/1.73m2, daily phosphate intake 1,544±347mg) completed the study. Correlations among dietary phosphate intake and biochemical measures, PWV, and abdominal aortic calcification ranged from r=-0.13 to r=+0.13. Linear regression showed no association between dietary phosphate measurements and biochemical or cardiovascular parameters. Source of phosphate intake was associated with PWV (P=.01), but not with other biomarkers of bone and mineral metabolism. Higher PWV values were associated with higher intake of plant-based relative to animal-based phosphate (1.058 [1.020-1.098], P=.003). Levels of total dietary phosphate intake measured by dietary food record show no statistically significant relationship with biochemical markers of bone and mineral metabolism or intermediate cardiovascular markers. Higher PWV levels associated with higher intake of plant-based relative to animal-based phosphate intake were an unexpected finding and further research is needed in this area.

439Reproducibility and relative validity of dietary patterns in older New Zealand adults

Abstract Background Valid and reproducible dietary patterns (DP) are necessary to assess relationships between diet and disease. This study, Researching Eating, Activity, and Cognitive Health (REACH), assessed the reproducibility and relative validity of DPs derived from a food frequency questionnaire (FFQ) in older New Zealand adults. Methods Participants (n = 294, 70±3yrs, 37% male), completed two identical 109-item FFQs to assess reproducibility. A 4-day food record (4DFR) was used to assess relative validity. After collapsing data into 57 food groups, DPs were derived using principal component analysis. Agreement of DP loadings were assessed using Tucker’s congruence coefficient. Agreement between derived DP scores from the FFQs and 4-DFR were assessed using Spearman correlation coefficients, weighted kappa statistic, and Bland-Altman analysis. Results Three similar DPs (‘Mediterranean style’, ‘Western’ and ‘prudent’) were identified from each dietary assessment tool. Congruence coefficients between DP loadings ranged from 0.66-0.80 (reproducibility) and 0.54-0.75 (validity). Correlations of DP scores ranged from 0.47-0.59 (reproducibility) and 0.33-0.43 (validity) (all P&amp;lt;0.001); weighted kappa scores ranged from 0.40-0.48 (reproducibility) and 0.27-0.37 (validity); limits of agreement from ±1.79 to ± 2.09 (reproducibility) and ±2.09 to ± 2.27 (validity); a negative slope of bias was seen in the ‘prudent’ pattern for reproducibility and validity (P&amp;lt;0.001). Conclusions The FFQ derived DPs demonstrated acceptable reproducibility and relative validity and can be used to examine associations between DPs and health outcomes in older New Zealand adults. Key Message Valid DPs improve evidence for assessing DP and health outcome associations.

Agreement of Food Records and 24-Hour Urine Studies in Clinical Practice

The objective of this study was to determine the level of agreement between 3-day food records obtained as part of clinical care with 24-hour urine collections specifically assessing sodium, potassium, phosphorus, calcium, protein, and fluid intake. Data were collected from patients at a nephrology clinic in a metropolitan, academic medical center. Patients who completed both a 3-day food record and a 24-hour urine collection were analyzed. Food record and urine collection measurements were compared using a simple ratio, Pearson's correlation, and general linear models. Patients (n=85) were 47.9±15.2years of age, 54% were female, with a mean serum creatinine of 1.3±0.7mg/dL and estimated glomerular filtration rate of 64.2±25.6mL/min. Patients had autosomal-dominant polycystic kidney disease (48.2%), nephrolithiasis (31.1%), chronic kidney disease (4.7%), or other genetic or cystic conditions impacting the kidney (12.9%). Nutrient intake was measured utilizing a 3-day food record. Food records and urine collections were compared using the values, correlations, and general linear models. Fluid intake demonstrated the highest agreement (ratio 1.01) and calcium demonstrated the least agreement (ratio 6.30). Significant correlations were demonstrated for phosphorus (r=0.321, P=.003), magnesium (r=0.256, P=.018), protein (r=0.555, P<.000), and fluid (r=0.277, P=.010) intake. Food record intake of potassium (P=.046), protein (P=.004), and fluid (P=.010) were significant predictors of 24-hour urine excretion. 3-day food records are useful tools to determine patient dietary patterns, but should be used with caution when assessing specific nutrient intake in clinical settings.

Feasibility and Acceptability of Photographic Food Record, Food Diary and Weighed Food Record in People with Serious Mental Illness.

People with serious mental illness (SMI) experience challenges that may make typical dietary assessment methods less feasible and accurate. This study aims to determine the feasibility, acceptability and preliminary validity of a 3-day photographic food record (PR), a 1-day food diary (FD) and a 1-day weighed food protocol (WR) in people with SMI. Participants completed measures at two timepoints, with a 4-week interval. Feasibility and acceptability for each method were measured through four outcomes: percent of completers, quality assessment, number of participants requiring technical devices and satisfaction questionnaire. Relative validity was measured by agreement in estimated energy intake between methods, using Bland–Altman analysis and WR as the benchmark, and prevalence of misreporting, using the Goldberg cut-off method, updated by Black. In total, 63 participants were recruited, with a dropout rate of 19.0% prior to timepoint 1 and additional 6.4% prior to timepoint 2. Quality deficits were identified for all methods. The FD was most acceptable to participants, followed by the PR. The difference in estimated energy intake between assessment methods was not statistically significant, though there was considerable individual variability. Underreporting was considerable across all methods but appeared highest in the PR. A FD and PR present as feasible and acceptable methods for assessing dietary intake in people with SMI. Further validity testing is required. In addition, clear guidance for completion and removal of potential barriers is required for participants.

The interplay between fasting, gut microbiota, and lipid profile.

This study aimed to investigate the consequence of Ramadan fasting on gut bacterium (Bacteroides and Firmicutes), serum concentration for butyrate, and lipid profile. Thirty healthy subjects were enlisted and investigated two times (before and at the end of Ramadan). Fasting blood samples were obtained for measuring fasting blood sugar (FBS) and lipid profile and serum butyrate concentration. Anthropometrics variables were measured before and after Ramadan for all 30 subjects. Quantitative reverse transcription polymerase chain reaction (RT-PCR) analysis, targeting the genome of Bacteroides and Firmicutes was performed to determine its presence in the stool samples. Food intake was assessed by a 3-day food record before and after Ramadan. Statistical analysis was performed by SPSS ver.13 and Minitab ver.17. P < 0.05 considered the level of significance. The study results showed that serum levels of butyrate significantly increase during the month from 0.23 ± 0.02 mM to 0.46 ± 0.03 mM (P < 0.05). The gut Bacteroides and Firmicutes increased by 21 and 13 percent after Ramadan compared to before (P < 0.05). The increment in Bacteroides occurred in both sexes, but Firmicutes significantly increased only in women. Food intake was decreased during Ramadan. Ramadan fasting caused significant reduction in BMI from 25.72 ± 0.58 kg/m2to 25.25 ± 0.55 kg/m2 (P < 0.05). Serum levels of LDL, HDL, LDL/HDL ratio, and total cholesterol significantly decreased during Ramadan (P < 0.05). However, the decrease in FBS and TG level were not statistically significant (P > 0.05). It can be stated that the promotion of Bacteroides and Firmicutes in the gut might play a crucial role in health promotion. However, more research is needed to achieve a definite conclusion.

The Need and Safety of Mineral Supplementation in Adults with Obesity Post Bariatric Surgery\u2014Sleeve Gastrectomy (SG)

PurposeMost of the research indicated that daily dietary intake of minerals in SG patients was lower than the current recommendations. The aim of the study was to assess the need and safety of a mineral supplementation practice in adults with obesity, at 3, 6, and 9 months post bariatric surgery—sleeve gastrectomy (SG).MethodsThe study included 24 women and 6 men. Based on a 4-day food record questionnaire, mineral and calorie intake was calculated at 3, 6, and 9 months after bariatric surgery (SG). Furthermore, an interview on supplement intake was also conducted.ResultsIt was found that in both men and women, there was a dietary intake deficiency of calcium (97% of respondents), potassium (97%), magnesium (83%), sodium (60%), and zinc (53%). In women, the deficiencies also included iron (50%) and copper (29%). Only 72% of the patients took dietary supplements. The applied supplementation did not adjust for the required intake of calcium in all of the patients, as well as the intake of magnesium in the male patients. Low intake of sodium and potassium were not supplemented and should be corrected by diet modification. The patients did not require supplementation of phosphorus or manganese, while male patients did not require iron or copper supplementation. The dietary and/or supplemental intake of minerals did not exceed the tolerable upper intake level (UL).ConclusionThe results of the study confirm the need to implement personalized mineral supplementation for bariatric surgery patients.Graphical abstract

Relative Validity and Reproducibility of a Food Frequency Questionnaire for Assessing Dietary Patterns and Food Group Intake in Older New Zealand Adults: The Researching Eating, Activity, and Cognitive Health Study

BackgroundDietary pattern analysis considers the overall dietary intake and combinations of foods eaten. Valid and reproducible tools for determining dietary patterns are necessary to assess diet–disease relationships. ObjectiveThis study evaluated the relative validity and reproducibility of the Researching Eating, Activity, and Cognitive Health (REACH) Study food frequency questionnaire (FFQ) specifically designed to identify dietary patterns in older adults. DesignA subset of participants from the REACH study completed two identical 109-item FFQs 1 month apart (FFQ1 and FFQ2) to assess reproducibility and a 4-day food record between FFQ administrations to assess relative validity. Foods from each dietary assessment tool were assigned to 57 food groups. Principal component analysis was applied to the food group consumption reported in each dietary assessment tool to derive dietary patterns. Participants and settingDietary data were collected (2018 and 2019) from a subset of the REACH study (n = 294, 37% men) aged 65 to 74 years, living in Auckland, New Zealand. Main outcome measuresDaily intakes of 57 food groups and dietary patterns of older adults participating in REACH living in New Zealand. Statistical analysisAgreement of dietary pattern loadings were assessed using Tucker’s congruence coefficient. Agreement of dietary pattern scores and food group intakes were assessed using Spearman correlation coefficients (acceptable correlation rho = 0.20 to 0.49), weighted kappa statistic (acceptable statistic κw = 0.20 to 0.60), and Bland-Altman analysis, including mean difference, limits of agreement, plots, and slope of bias. ResultsThree similar dietary patterns were identified from each dietary assessment tool: Mediterranean style, Western, and prudent. Congruence coefficients between factor loadings ranged from 0.54 to 0.80. Correlations of dietary pattern scores ranged from 0.47 to 0.59 (reproducibility) and 0.33 to 0.43 (validity) (all P values < 0.001); weighted kappa scores from 0.40 to 0.48 (reproducibility) and 0.27 to 0.37 (validity); limits of agreement from ± 1.79 to ± 2.09 (reproducibility) and ± 2.09 to ± 2.27 (validity); a negative slope of bias was seen in the prudent pattern for reproducibility and validity (P < 0.001). ConclusionsThe REACH FFQ generated dietary patterns with acceptable reproducibility and relative validity and therefore can be used to examine associations between dietary patterns and health outcomes in older New Zealand adults.

The Effects of Date Fruit Consumption on Breast Milk Quantity and Nutritional Status of Infants.

Background: Date fruit is a popular natural galactagogue among breastfeeding Muslim mothers. However, there is no evidence to support the effectiveness of date fruit in increasing the quantity of breast milk. Objective: This research aimed to study the effect of date fruit consumption on breast milk quantity and nutritional status of infants. Materials and Methods: This was a parallel randomized controlled trial. Forty-eight pairs of breastfeeding mothers and infants aged 1-3 months were included. The intervention group (n = 25) was asked to consume their normal dietary intake with 10 date fruits/day for 4 weeks. The control group (n = 23) was asked to consume their normal dietary intake without date fruit. Breast milk quantity was measured by using an electric breast pump and recorded for 2 days at baseline, week 2 and 4. The nutritional status of infants was assessed by calculating infant weight-for-age at baseline and week 4. Dietary data were collected at baseline, week 2, and 4, using a 2-day food record. Data were analyzed using Chi-square, t-test Mann-Whitney U test, and Wilcoxon matched-pairs signed-ranks test by SPSS version 18.0. Results: Breastfeeding mothers who received 10 date fruits/day had an 11% increase in breast milk quantity from baseline to week 2, and a 23% increase from baseline to week 4, (both p < 0.05). The breast milk quantity of the breastfeeding mothers who received date fruits was significantly higher than that of the control group (p < 0.05). However, there were no differences in infant nutritional status. Conclusions: Date fruit consumption appears to be useful for promoting and increasing breast milk quantity in breastfeeding mothers. Date fruits may be an alternative galactagogue.

Novel Application of Nutritional Biomarkers From a Controlled Feeding Study and an Observational Study to Characterization of Dietary Patterns in Postmenopausal Women

Dietary guidance emphasizes healthy dietary patterns, but supporting evidence comes from self-reported dietary data, which are prone to measurement error. We explored whether nutritional biomarkers from the Women's Health Initiative Nutrition and Physical Activity Assessment Study Feeding Study (NPAAS-FS) (n=153; 2010-2014) and the Women's Health Initiative Nutrition and Physical Activity Assessment Study Observational Study (NPAAS-OS) (n=450; 2006-2009) could identify biomarker signatures of dietary patterns for development of corresponding regression calibration equations to help mitigate measurement error. Fasting blood samples were assayed for a specific panel of vitamins, carotenoids, and phospholipid fatty acids; 24-hour urine samples were assayed for nitrogen, sodium, and potassium levels. Intake records from the NPAAS-FS were used to calculate Healthy Eating Index 2010 (HEI-2010), Alternative Healthy Eating Index 2010 (AHEI-2010), alternative Mediterranean diet (aMED), and Dietary Approaches to Stop Hypertension (DASH) scores. Scores were regressed on blood and urine nutritional measures for discovery of dietary pattern biomarkers using a cross-validated model R2 ≥ 36% criterion (stage 1). Next, stepwise models (P≤0.10 for entry/removal) using NPAAS-OS data were used to regress stage 1 dietary pattern biomarkers on NPAAS-OS self-reported dietary pattern scores using a food frequency questionnaire, a 4-day food record, and a 24-hour recall (stage 2). HEI-2010 and aMED analyses met the cross-validated R2 ≥36% criterion in stage 1, while AHEI-2010 and DASH analyses did not. The R2 values for HEI-2010 stage 2 calibration equations were as follows: food frequency questionnaire, 63.5%; 4-day food record, 83.1%; and 24-hour recall, 77.8%. Stage 2 aMED R2 values were 34.9%-46.8%. Dietary pattern biomarkers have potential for calibrating self-reports to enhance studies of diet-disease associations.

Effect of early childhood cow's milk elimination diet on eating behaviours, nutrition and growth status at age 2-6years.

The present study aimed to investigate the eating behaviour, nutritional status and growth of Caucasian children in ages 2-6years who had a diet because of cow's milk protein allergy (CMA) [immunoglobulin (Ig)E-mediated and/or non-IgE-mediated] in early childhood. In this cross-sectional, case-control study, the cow's milk elimination (CME) group comprised children aged 0-2years who were receiving a CME diet because of CMA, as confirmed by an oral food challenge test, and had reintroduced cow's milk for at least ≥3months. The control group never had a restricted diet. Eating behaviour and children's growth was assessed. A 3-day food record was taken to determine the macronutrient and micronutrient intake of the children. Data on the children's socio-demographic, infant nutrition and family allergy history were collected from their medical records and face-to-face interviews with mothers. In total, 62 children with a median age of 32months were recruited for the study. The total scores of food avoidance and satiety responsiveness in the CME group (n:31) were higher than in the controls (n=31) (p=0.036 and 0.006, respectively). Weight-for-age and height-for-age are statistically lower in the CME group than in the control group (p<0.001). A significant difference between groups in terms of dairy intake was recorded (p=0.011). In the CME group, the current frequency of adequate energy, vitamin B1, folic acid, vitamin C and calcium intake was significantly lower than in the control group (p<0.05). Dietary interventions because of CMA at age 0-2years can affect children's nutritional habits and parental-reported assessment of children's eating behaviours, resulting in growth restriction with insufficient micro/macronutrients and/or dairy products at the age of 2-6years.

Assessment of Nutrition Status in Amateur Windsurfers during Regattas in the Competitive Period—A Field Study

Windsurfing is a demanding activity that requires a high level of physical fitness as well as appropriate training and nutritional strategies. Therefore, the aim of this study was to assess the dietary intake of amateur windsurfers and consider possible dietary mistakes. This field study was conducted among 10 Polish male amateur windsurfers (aged 22 ± 2 years, mean training experience of 9.5 ± 4 years). Dietary intake was assessed using a standardized 3-day food record. The total energy expenditure of each participant was estimated using a mobile fitness application. The daily energy supply in assessed portions of the windsurfers’ food was lower than the estimated demand during the competition. The contribution of macronutrients to the total energy intake adhered to those guidelines, but not with the ones recommended for athletes practicing extreme sports. Daily fluid consumption was insufficient. In the windsurfers’ diet, we noticed low consumption of vitamin D and calcium, while cholesterol, sodium, potassium, and phosphorus intake was too high. Nutritional practices of amateur windsurfers during the competitive period do not comply with current sports nutrition guidelines. The results suggest that windsurfers are in need of nutritional education and dietary counseling in order to meet macronutrient intake targets.

Nutrition status of adults with phenylketonuria treated with pegvaliase

BackgroundPegvaliase is an enzyme substitution therapy that reduces blood phenylalanine (Phe) in adults with phenylketonuria (PKU), and often allows normalization of protein intake (≥0.8 g protein/kg).Here we examine the nutrition status of adults with PKU consuming a normal protein intake without medical food after being treated with pegvaliase for ≥1 year. MethodsA cross-sectional study evaluating nutritional intake (3-day food record and food frequency questionnaire), anthropometrics, laboratory indices of protein, micronutrient, and essential fatty acid (EFA) status, and questionnaires evaluating food neophobia and Epicurean eating pleasure. ResultsParticipants (n = 18, 61% female) started pegvaliase 4.9 ± 2.1 years prior to enrollment and were aged 38.2 ± 8.8 years with a mean BMI of 29.2 ± 4.1 kg/m2. Participants consumed a mean of 73.2 ± 17.6 g protein/d (1.0 ± 0.3 g/kg/d). Eleven participants had low blood Phe (<30 μmol/L) with adequate protein intake and normal indices of protein status. Micronutrient and EFA concentrations were normal except for mildly low vitamin D (<30 ng/mL, n = 12). Intakes of sodium, saturated fat, and added sugars exceeded recommendations for healthy adults, though mean diet quality was comparable to a US adult reference population. Lower food neophobia scores correlated with an increased aesthetic appreciation of food. However, 53% of participants self-reported having moderate (n = 6) to high (n = 3) food neophobia. DiscussionParticipants treated with pegvaliase consumed an unrestricted diet with adequate dietary protein and, overall, had normal protein, micronutrient, and fatty acid status. Despite low blood Phe, protein nutriture was not compromised. While nutritional deficiencies were not identified, diet quality was suboptimal and some participants reported food neophobia. Nutrition education remains an important component of care as patients adapt to a normal diet.

Policy and Food Consumption: What Nutrition Guidelines Are Swiss Children Meeting and What Determines Adherence?

Objectives: To describe the adherence of the children to the Swiss Society for Nutrition (SSN) dietary guidelines, assess determinants of adherence, and compare these findings with a previous study in the same population.Methods: Data from 312 children ages 5–12 were collected through a survey and a 2-day food record. The associations of children- and parent-related factors with adherence of the children to guidelines were assessed by logistic regression analyses.Results: SSN guidelines were not met for any food category, although there were improvements: vegetables (4.5% in this study vs. 0% in the previous study), sweets, snacks, and soft drinks (SSD) (12.5 vs. 9.5%), and fruit (45.5 vs. 10.4%). Higher Body Mass Index (BMI) in children was associated with higher adherence to guidelines for protein intake. Higher parental BMI was associated with higher adherence to vegetables. Parental lower educational level was associated with higher adherence for cereal.Conclusion: Despite improvements since the last eating behavior assessment in this population, children consume too little fruit, vegetables, cereal, and milk and dairy products, and too much SSD and proteins. Further efforts are needed to promote healthy eating to children and achieve adherence to guidelines.

Prevalence of Normal Weight Obesity and Health Risk Factors for the Female Collegiate Dancer.

Brown, AF, Alfiero, CJ, Brooks, SJ, Kviatkovsky, SA, Smith-Ryan, AE, and Ormsbee, MJ. Prevalence of normal weight obesity and health risk factors for the female collegiate dancer. J Strength Cond Res 35(8): 2321-2326, 2021-The purpose of this study was to investigate the prevalence of normal weight obesity (NWO) and evaluate the relationship between NWO and health risk factors in a collegiate dancer population. Reanalysis of data of female dancers (N = 42) from 2 larger studies was used to assess prevalence and health risk factors of NWO. Dancers completed a dual-energy x-ray absorptiometry scan to assess fat mass (FM), lean mass (LM), and visceral adipose tissue (VAT) and a 3-day food record. Normal weight obesity was defined as a body mass index (BMI) of 18.5-24.9 kg·m-2 and body fat (BF) ≥30%. Twenty-five (60%) dancers were classified as normal weight lean (NWL), and 17 dancers (40%) were classified as NWO. Significant differences were observed for BMI (NWL: 21.1 ± 1.7, NWO: 23.1 ± 1.6, p < 0.001), LM (NWL: 71.0 ± 2.9%, NWO: 62.5 ± 2.7%, p < 0.001), %BF (NWL: 24.8 ± 3.1%, NWO: 33.9 ± 2.6%, p < 0.001), and VAT (NWL: 130.6 ± 43.0 g, NWO: 232.3 ± 70.8 g, p < 0.001) between NWL and NWO. A significant difference was observed for carbohydrate intake (NWL: 4.7 ± 1.8 g·kg-1, NWO: 3.7 ± 1.0 g·kg-1, p = 0.020) between groups. Significant positive correlations with FM were observed between carbohydrate (kcal, p = 0.048), fat (kcal, p = 0.018; g·kg-1, p = 0.040), and total calories (p = 0.019) in NWO. Normal weight obesity in collegiate dancers may be more prevalent than previously perceived and may be significantly related to important health risk factors. The current study demonstrates the need for body composition assessments and emphasizing on promoting overall health in collegiate dancers.

Associations Between Chrononutrition With Sleep Quality and Melatonin Rhythm of Pregnant Women

Abstract Objectives Chrononutrition is referred to as a zeitgeber for its ability to synchronize the circadian rhythm. In addition to the role as circadian marker, sleep and melatonin are important factors for optimal maternal and infant outcomes. Understanding the chrononutrition factors associated with sleep quality and melatonin rhythm during pregnancy has practical importance for preventive care. Hence, this study aimed to examine the association between chrononutrition with sleep quality and melatonin rhythm during pregnancy. Methods A total of 114 primigravidas were recruited at randomly selected government maternal and child clinics in Kuala Lumpur, Malaysia. Gestational age and pre-pregnancy body mass index (BMI) were extracted from clinic records. Components of chrononutrition including meal timing, meal frequency, eating window, breakfast skipping, and night eating were assessed using 3-day food record. Sleep quality in the third trimester was determined using Pittsburgh Sleep Quality Index (PSQI). Subsample (n = 48) provided salivary samples at 4 time-points (9:00, 15:00, 21:00 and 3:00 h) over 24 hours for melatonin assay. Results The mean gestational age of participants was 33.0 (2.1) weeks; 13% were underweight and 22% were overweight/obese before pregnancy. Average daily meal frequency was 4.1 (0.9). The majority (68%) practiced a shorter eating window (≤12 hours); 25% skipped breakfast and 19% ate within 2 hours pre-bedtime. The prevalence of poor sleep among the participants was 56%. Mean salivary melatonin level was 19.6 (16.3) pmol/L. In the adjusted linear regression model, lower meal frequency and fat intake during dinner were significant predictors of poor sleep quality (β = −0.266, P = 0.035 and β = −0.232, P = 0.026, respectively). Eating nearer to bedtime was significantly associated with greater deviation of melatonin acrophase from mid-sleep clock time (β = −0.339, P = 0.043). Conclusions Findings suggested that unfavorable characteristics of chrononutrition may contribute to poor sleep and misalignment of melatonin phase. Components of chrononutrition may be incorporated into meal intervention to improve maternal sleep quality and circadian health.

The Correlation Between Caffeine Intake and Brain Health in Cognitively Normal Healthy Older Adults

Abstract Objectives Caffeine is associated with brain health, and it is suggested to lower the risk of neurological diseases. This cross-sectional study aimed to investigate the association between caffeine intake and concentration of brain metabolites in healthy older adults. Methods Caffeine intake was determined in 60 cognitively normal, healthy older adults aged between 60–85 years (61.9% women) using a 7-day food record (7D) that was collected seven days prior to their Magnetic Resonance scan. The 7D was entered in the Nutrition Data System for Research (NDS-R version 2012) for nutrient analysis. Brain metabolites [N-acetylaspartate, creatine, total choline, glutamate + glutamine, and myo-inositol (mI)] were measured using a 1H magnetic resonance spectroscopic imaging method at 3T. All metabolites were quantified using LCModel analysis software and concentrations are shown as a ratio to creatine. Measurements were presented as mean ± standard deviation and n(%). We assessed the relationship between caffeine intake and brain metabolite concentrations by multiple linear regression, adjusting for age and sex. Statistical analyses were performed using SPSS (v25, IBM) with significance of P ≤ 0.05. Results Participants had a mean age of 69.3 ± 7.3 years. Mean caffeine intake among the participants was 152.17 ± 133.79mg/d (range: 0–635.98mg/d). There was a significant correlation between caffeine and mI (β = 0.443; P = 0.001). The remaining metabolites were not correlated with caffeine intake. Conclusions Higher caffeine intake in older adults was associated with higher brain mI concentrations. The metabolic link between brain mI concentrations and neurological diseases is still unclear, thus, future studies are necessary regarding the mechanism for the impact of caffeine on brain metabolism.

Carbohydrate Quality of a Middle-aged and Older Population in Singapore and Its Association with Cardiometabolic Health

Abstract Objectives Carbohydrate quality plays a key role in cardiometabolic health, though this has not been well investigated in Asian populations. This study aimed to assess the carbohydrate quality of middle-aged and older adults in Singapore, and its association with various cardiometabolic health-related markers. Methods A secondary data analysis of a cross-sectional study consisting of 104 adults (59 ± 6 years, mean ± SD) was conducted. Carbohydrate quality was evaluated by their adherence to: (i) Singapore recommended daily allowance (RDA) for dietary fiber intake, (ii) Singapore recommended daily whole grain intake, (iii) World Health Organization free sugars limit and (iv) the balanced carbohydrate metrics (BCM). The BCM was reflected by a ratio of at least 1g of fiber per 10g of carbohydrates (10:1, simple ratio), or variations including free sugars criteria. Food intake was collected using 3-day food record. Measurements of cardiometabolic health-related markers were body mass index, waist circumference, blood pressure, blood lipid-lipoprotein markers (total, low-density lipoprotein and high-density lipoprotein cholesterol and triglycerides) and glucose and 10-year risk to coronary heart disease. The association between dietary carbohydrate quality and cardiometabolic health-related markers, as well as associations amongst the 4 measures of carbohydrate quality were evaluated using Fisher's exact test. Results 36%, 20%, 87% and 34% of the population met the fiber RDA, whole grain recommendation, free sugars limit and BCM respectively. A significant association in adherence to each measure of carbohydrate quality was found across all 4 measures (P &amp;lt; 0.05), except for between the whole grain recommendation and free sugars limit. The simple ratio was associated with a lower systolic blood pressure (P = 0.04) while no association was observed with other cardiometabolic health-related markers. Conclusions Consuming a diet adhering to the simple ratio of at least 1g of fiber for every 10g of carbohydrates may improve blood pressure and subsequently lower cardiometabolic disease risk.
