Middle East consensus recommendations on the use of young child formula (YCF) in toddlers.

The transition of foods during toddlerhood and the suboptimal diets consumed in the Middle East make children susceptible to malnutrition and micronutrient deficiencies. Based on international recommendations, coupled with the merits of clinical studies on the application of young child formula (YCF), a group of fourteen experts from the Middle East reached a consensus on improving the nutritional status of toddlers. The recommendations put forth by the expert panel comprised twelve statements related to the relevance of YCF in young children; the impact of YCF on their nutritional parameters and functional outcomes; characteristics of the currently available YCF and its ideal composition; strategies to supply adequate nutrition in young children and educational needs of parents and healthcare professionals (HCPs). This consensus aims to serve as a guide to HCPs and parents, focusing on improving the nutritional balance in toddlers in the Middle Eastern region. The panellists considere YCF to be one of the potential solutions to improve the nutritional status of young children in the region. Other strategies to improve the nutritional status of young children include fortified cow's milk and cereals, vitamin and mineral supplements, early introduction of meat and fish, and the inclusion of diverse foods in children's diets.

Academy of Nutrition and Dietetics Nutrition Research Network: A Home Garden Intervention Improves Child Length-for-Age Z-Score and Household-Level Crop Count and Nutritional Functional Diversity in Rural Guatemala.

Home gardens may help address childhood malnutrition in low- and middle-income countries. In this quasi-experimental pilot study, the Academy of Nutrition and Dietetics, in collaboration with Maya Health Alliance, evaluated the feasibility of augmenting a standard-of-care nutrition-specific package for Maya children with length-for-age z score ≤-2 (stunting) in rural Guatemala with a nutrition-sensitive home garden intervention. Two agrarian municipalities in Guatemala were included. Families of 70 children with stunting from 1 municipality received the standard-of-care package (food supplementation, multiple micronutrient powders, monthly nutrition home visits, group nutrition classes). Families of 70 children with stunting from another municipality received the standard-of-care package plus a home garden intervention (garden materials, monthly agricultural home visits, agriculture classes). Maternal and child dietary diversity, household food insecurity, child growth, and agricultural indicators were collected at baseline and 6 months later and were analyzed using mixed linear and logistic regression models. Compared with the standard-of-care group, the garden intervention group had improved child (odds ratio [OR] 3.66, 95% CI 0.89-15.10, P = 0.07) and maternal dietary diversity (OR 2.31, 95% CI 0.80-6.65, P = 0.12) and decreased food insecurity (OR 0.38, 95% CI 0.11-1.35, P = 0.14); however, these effects were not statistically significant. Participation in gardens predicted a higher length-for-age z-score (change difference [CD] 0.22 SD, 95% CI 0.05-0.38, P = 0.009), greater crop species count (CD 2.97 crops, 95% CI 1.79-4.16, P < 0.001), and greater nutritional functional diversity (CD 0.04 points, 95% CI 0.01-0.07, P = 0.006) than standard-of-care alone. Home garden interventions are feasible in rural Guatemala and may have potential benefits for child growth when added to other nutrition-specific interventions.

ESPEN guideline on hospital nutrition.

In hospitals through Europe and worldwide, the practices regarding hospital diets are very heterogeneous. Hospital diets are rarely prescribed by physicians, and sometimes the choices of diets are based on arbitrary reasons. Often prescriptions are made independently from the evaluation of nutritional status, and without taking into account the nutritional status. Therapeutic diets (low salt, gluten-free, texture and consistency modified, …) are associated with decreased energy delivery (i.e. underfeeding) and increased risk of malnutrition. The European Society for Clinical Nutrition and Metabolism (ESPEN) proposes here evidence-based recommendations regarding the organization of food catering, the prescriptions and indications of diets, as well as monitoring of food intake at hospital, rehabilitation center, and nursing home, all of these by taking into account the patient perspectives. We propose a systematic approach to adapt the hospital food to the nutritional status and potential food allergy or intolerances. Particular conditions such as patients with dysphagia, older patients, gastrointestinal diseases, abdominal surgery, diabetes, and obesity, are discussed to guide the practitioner toward the best evidence based therapy. The terminology of the different useful diets is defined. The general objectives are to increase the awareness of physicians, dietitians, nurses, kitchen managers, and stakeholders towards the pivotal role of hospital food in hospital care, to contribute to patient safety within nutritional care, to improve coverage of nutritional needs by hospital food, and reduce the risk of malnutrition and its related complications.

Association of food insecurity with dietary intakes and nutritional biomarkers among US children, National Health and Nutrition Examination Survey (NHANES) 2011-2016.

BACKGROUND: Food insecurity is associated with poorer nutrient intakes from food sources and lower dietary supplement use. However, its association with total usual nutrient intakes, inclusive of dietary supplements, and biomarkers of nutritional status among US children remains unknown. OBJECTIVE: The objective was to assess total usual nutrient intakes, Healthy Eating Index-2015 (HEI-2015) scores, and nutritional biomarkers by food security status, sex, and age among US children. METHODS: Cross-sectional data from 9147 children aged 1-18 y from the 2011-2016 NHANES were analyzed. Usual energy and total nutrient intakes and HEI-2015 scores were estimated using the National Cancer Institute method from 24-h dietary recalls. RESULTS: Overall diet quality was poor, and intakes of sodium, added sugars, and saturated fat were higher than recommended limits, regardless of food security status. Food-insecure girls and boys were at higher risk of inadequate intakes for vitamin D and magnesium, and girls also had higher risk for inadequate calcium intakes compared with their food-secure counterparts, when total intakes were examined. Choline intakes of food-insecure children were less likely to meet the adequate intake than those of their food-secure peers. No differences by food security status were noted for folate, vitamin C, iron, zinc, potassium, and sodium intakes. Food-insecure adolescent girls aged 14-18 y were at higher risk of micronutrient inadequacies than any other subgroup, with 92.8% (SE: 3.6%) at risk of inadequate intakes for vitamin D. No differences in biomarkers for vitamin D, folate, iron, and zinc were observed by food security status. The prevalence of iron deficiency was 12.7% in food-secure and 12.0% in food-insecure adolescent girls. CONCLUSIONS: Food insecurity was associated with compromised intake of some micronutrients, especially among adolescent girls. These results highlight a need for targeted interventions to improve children's overall diet quality, including the reduction of specific nutrient inadequacies, especially among food-insecure children. This study was registered at clinicaltrials.gov as NCT03400436.

Diet Quality, Nutritional Adequacy, and Sociodemographic Characteristics of Mobile Food Pantry Users in Northeastern Connecticut.

Poor diet quality among low-income populations is a major contributing factor to their poor health and wellbeing, and thus is a focus of many government aid programs. Mobile food pantries are an increasingly popular method of emergency food assistance, targeting the communities most affected by food insecurity; however, little is known about the dietary characteristics of mobile food pantry users. This study aims to characterize the diet quality and nutrient adequacy level and examine its association with sociodemographic characteristics among mobile food pantry users in Windham County, Connecticut. Surveys to assess food insecurity, diet composition, and sociodemographic characteristics were administered to 83 adult food pantry users. Participants (n = 40) completed a three-day dietary record for analysis of diet quality, and were found to have inadequate intakes of fruits, vegetables, whole grains and dairy, as well as some related micronutrients. At least 30% of participants had intakes below the Estimated Average Requirement (EAR) for vitamins A, C, E, calcium, zinc, magnesium, and folate. Intakes of added sugar, sugar sweetened beverages, and saturated fat were also above recommendations according to the United States Dietary Guidelines. Certain sociodemographic factors affected diet quality among this sample. For example, being male was associated with increased sugar-sweetened beverage and added sugar intake. This characterization of mobile pantry users will serve as a reference for developing nutrition education and determining the effectiveness of future interventions.

A longitudinal impact evaluation of a comprehensive nutrition program for reducing stunting among children aged 6-23 months in rural Malawi.

BACKGROUND: Growth failure in sub-Saharan Africa leads to a high prevalence of child stunting starting in infancy, and is attributed to dietary inadequacy, poor hygiene, and morbidity. OBJECTIVES: To evaluate the impact of a program in Malawi providing a lipid-based nutrient supplement to infants from 6-23 months of age, accompanied by a social and behavior change communication intervention to optimize caregiver feeding and handwashing practices. METHODS: This impact evaluation was a quasi-experimental, longitudinal study with 1 program and 1 comparison district. Infants were enrolled at 6-7 months of age. Anthropometry, child morbidity, and caregiver feeding and handwashing practices were assessed at enrollment and at 6, 12, and 18 month follow-ups (ages 6, 12, 18, and 24 months, respectively). Changes in the length-for-age z-score (LAZ), weight-for-length z-score (WLZ), and midupper arm circumference (MUAC) were compared using mixed-effects models. Program impacts on child stunting (LAZ < -2), wasting (WLZ < -2), morbidity, and feeding and handwashing practices were estimated using difference-in-differences. RESULTS: We enrolled 367 infants across the program (n = 176) and comparison (n = 191) districts. The combined prevalences of stunting and wasting at enrollment were 42.1% and 1.4%, respectively, and did not differ by district. At enrollment, the prevalence of severe stunting (LAZ < -3) was higher in the program (15.5%) versus comparison (7.6%) district (P = 0.02), with corresponding lower LAZ scores (-1.9 vs. -1.7, respectively; P = 0.12). Growth velocities favored program children, such that LAZ, WLZ, and MUAC measurements increased by +0.12/y (P = 0.06), +0.12/y (P = 0.04), and +0.24 cm/y (P < 0.001), respectively, leading to comparable LAZ distributions across districts by 24 months of age. Program exposure was associated with 19.8 percentage point (pp) and 13.8 pp reductions in the prevalences of malaria (P = 0.001) and fever (P = 0.02), respectively, at the 18-month follow-up. Improvements of 20 pp (P < 0.01) in minimum dietary diversity and minimum acceptable diet were seen in the program versus comparison district at 18 months of follow-up. CONCLUSIONS: The program improved child growth patterns, with benefits to health and diet apparent after 18 months of exposure. This trial was registered at clinicaltrials.gov as NCT02985359.

Current practice in nutrition after allogeneic hematopoietic stem cell transplantation - Results from a survey among hematopoietic stem cell transplant centers.

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (alloHSCT) is frequently associated with impaired oral intake and malnutrition, which potentially increases morbidity and mortality. Therefore, nutrition is one of the major challenges in the post-transplant period. METHODS: To document the current clinical approach in nutritional treatment, we designed a questionnaire concerning the current practice in nutrition after alloHSCT and distributed it to German speaking centers performing alloHSCT in Germany, Austria and Switzerland between November 2018 and March 2020. Twenty-eight (39%) of 72 contacted centers completed the survey, 23 from Germany, two from Austria and three from Switzerland, representing 50% of alloHSCT activity within the participating countries in 2018. RESULTS: All centers reported having nutritional guidelines for patients undergoing alloHSCT, whereby 86% (n = 24) provided a low-microbial diet during the neutropenic phase. The criteria to start parenteral nutrition (PN) directly after alloHSCT seemed to be consistent, 75% (n = 21) of the corresponding centers started PN if the oral nutritional intake or the bodyweight dropped below a certain limit. In the setting of intestinal graft-versus-host disease (GvHD) the current practice appeared to be more heterogenous. About 64% (n = 18) of the centers followed a special diet, added food stepwise modulated by GvHD symptoms, while only four centers regularly stopped oral intake completely (intestinal GvHD grade >1). Half of the centers (54%, n = 15) applied a lactose-free diet, followed by 43% (n = 12) which provided fat- and 18% (n = 5) gluten-free food in patients with intestinal GvHD. Supplementation of micronutrients in acute intestinal GvHD patients was performed by 54% (n = 15) of the centers, whereas vitamin D (89%, n = 25) and vitamin B12 (68%, n = 19) was added regularly independently of the presence of GvHD. Only 5 (18%) participating centers ever observed a food-associated infection during hospitalization, whereas food-associated infections were reported to occur more often in the outpatient setting (64%, n = 18). CONCLUSION: The survey documented a general consensus about the need for nutritional guidelines for patients undergoing alloHSCT. However, the nutritional treatment in clinical practice (i.e. lactose-, gluten- or fat-free in intestinal GvHD) as well as the use of food supplements was very heterogeneous. In line with current general recommendations the centers seemed to focus on safe food handling practice rather than providing a strict neutropenic diet. More high-quality data are required to provide evidence-based nutrition to patients during and after alloHSCT.

Vitamin B-6 intake is related to physical performance in European older adults: results of the New Dietary Strategies Addressing the Specific Needs of the Elderly Population for Healthy Aging in Europe (NU-AGE) study.

BACKGROUND: Maintenance of high physical performance during aging might be supported by an adequate dietary intake of niacin, vitamins B-6 and B-12, and folate because these B vitamins are involved in multiple processes related to muscle functioning. However, not much is known about the association between dietary intake of these B vitamins and physical performance. OBJECTIVES: The objectives of this study were to investigate the association between dietary intake of niacin, vitamins B-6 and B-12, and folate and physical performance in older adults and to explore mediation by niacin status and homocysteine concentrations. METHODS: We used baseline data from the New Dietary Strategies Addressing the Specific Needs of the Elderly Population for Healthy Aging in Europe (NU-AGE) trial, which included n = 1249 healthy older adults (aged 65-79 y) with complete data on dietary intake measured with 7-d food records and questionnaires on vitamin supplement use and physical performance measured with the short physical performance battery and handgrip dynamometry. Associations were assessed by adjusted linear mixed models. RESULTS: Intake of vitamin B-6 was related to lower chair rise test time [ß: -0.033 ± 0.016 s (log); P = 0.043]. Vitamin B-6 intake was also significantly associated with handgrip strength, but for this association, a significant interaction effect between vitamin B-6 intake and physical activity level was found. In participants with the lowest level of physical activity, higher intake of vitamin B-6 tended to be associated with greater handgrip strength (ß: 1.5 ± 0.8 kg; P = 0.051), whereas in participants in the highest quartile of physical activity, higher intake was associated with lower handgrip strength (ß: -1.4 ± 0.7 kg; P = 0.041). No evidence was found for an association between intake of niacin, vitamin B-12, or folate and physical performance or for mediation by niacin status or homocysteine concentrations. CONCLUSIONS: Vitamin B-6 intake was associated with better chair rise test time in a population of European healthy older adults and also with greater handgrip strength in participants with low physical activity only. Homocysteine concentrations did not mediate these associations. The NU-AGE trial was registered at clinicaltrials.gov as NCT01754012.

Calcium and available phosphorus requirements of Japanese quails in early egg-laying stage.

An experiment was conducted to estimate the nutritional requirements of calcium (Ca) and available phosphorus (aP) for Japanese quails (Coturnix coturnix japonica) in the egg-laying stage (64-168 D). The experiment was an entirely randomized design, in a factorial scheme (Ca = 1.70, 2.40, 3.10, and 3.80% and aP = 0.15, 0.30, 0.45, and 0.60%), with 3 replicates and 10 quails per experimental unit. No interactions were found for quail body weight and daily feed intake (DFI) (P > 0.05). However, body weight decreased linearly (P < 0.05) as the levels of Ca increased, whereas DFI exhibited a quadratic effect (P < 0.05) for both Ca and aP. The lowest values of DFI were estimated in 2.79 and 0.36% for Ca and aP, respectively. Egg production, egg mass, and feed conversion ratio per egg dozen presented significant interaction in which all of them had a quadratic effect (P < 0.05), with estimations for maximum yield in feed containing 2.74, 2.71, 2.75, and 2.74% Ca and 0.40, 0.39, 0.39, and 0.40% aP. The concentration of Ca in the eggshell increased linearly as per the levels of Ca studied, having a quadratic effect for aP levels, with a maximum point of 0.44%. In relation to the bone parameters, there was a linear interaction for Ca and aP in bone density and bone resistance (BR) of the femur, with a quadratic effect in BD estimating 2.84 and 0.50% for Ca and aP, respectively. In BR, the estimation was 3.27% Ca, with linear increase for aP. The BR of the tibiotarso increased linearly as per the Ca levels, obtaining the same Ca concentration response in this bone. As conclusion, when considering the estimations obtained through overlapped contour plots, the best responses to the effects of Ca and aP on productive characteristics were estimated at 2.68% Ca and 0.38% aP to produce feed for egg-laying Japanese quails.

The Influence of Mindful Eating and/or Intuitive Eating Approaches on Dietary Intake: A Systematic Review.

BACKGROUND: Stimuli that promote eating in the absence of the physiological need for food are pervasive and can facilitate excessive energy intake. The practices of mindful eating (ME) and intuitive eating (IE) have been developed to minimize external drivers of energy intake by helping individuals emphasize the sensory properties of foods and internal indicators of hunger and fullness. OBJECTIVE: To enhance understanding about the effect of ME and IE interventions on dietary intake, this systematic review included randomized trials of ME and IE interventions that examined dietary intake, defined as energy intake or diet quality, in adults of varying weight status without a diagnosis of an eating disorder. METHODS: The selection of literature followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses systematic review process, in which PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and PsycINFO databases were searched for studies published between January 1980 and November 2019. Studies were included if they met the following criteria: randomized trial design in which 1 arm was an intervention with an ME or IE component and there was at least 1 control or active comparison arm; enrolled participants were of a healthy weight or with overweight or obesity and reported not having an eating disorder (ie, anorexia, bulimia nervosa, or binge eating disorder) or other health conditions in which dietary restrictions were applied; were at least 18 years of age; and outcomes of energy intake or diet quality were reported at baseline and post intervention. The modified Downs and Black checklist was used to assess risk of bias for each study that met inclusion criteria. RESULTS: A total of 13 studies, including 8 investigating ME interventions and 5 investigating IE interventions, represented in 14 articles, were included in the review. Seven of the 9 articles reporting on energy intake did not find significant group differences. Eight of the 12 articles reporting on diet quality did not find significant group differences. The mean bias assessment score was 13.6 out of 28, indicating poor quality. CONCLUSIONS: Little evidence suggests that ME and IE interventions influence energy intake or diet quality. To draw strong conclusions about the effect of ME and IE on dietary intake, future research using study designs of high rigor are needed.

Relationship between Dispositional Mindfulness, Psychological Health, and Diet Quality among Healthy Midlife Adults.

Mindfulness, a practice of non-judgmental awareness of present experience, has been associated with reduced eating psychopathology and emotion-driven eating. However, it remains unclear whether mindfulness relates to diet quality. Thus, the purpose of this study was to examine whether dispositional mindfulness is associated with diet quality and to explore psychological factors relating dispositional mindfulness to diet quality. Community-dwelling adults (N = 406; Mage = 43.19, SD = 7.26; Mbody mass index [BMI] = 27.08, SD = 5.28; 52% female) completed ratings of dispositional mindfulness, depressive symptoms, perceived stress, positive affect (PA), and negative affect (NA). Dietary intake was assessed using the Block Food Frequency Questionnaire, from which the 2015 Healthy Eating Index was derived. Analyses were conducted using the "lavaan" package in R with bias-corrected bootstrapped confidence intervals (BootCI). Age, sex, race, education, and BMI were entered as covariates in all models. Higher dispositional mindfulness was associated with higher diet quality (ß = 0.11, p = 0.03), and this effect was mediated through lower depressive symptoms (indirect effect ß = 0.06, p = 0.02, BootCI = 0.104-1.42, p = 0.03). Dispositional mindfulness was negatively correlated with perceived stress (ß = -0.31, p < 0.01) and NA (ß = -0.43, p < 0.01), as well as positively correlated with PA (ß = -0.26, p < 0.01). However, these factors were unrelated to diet quality. These cross-sectional data provide initial evidence that dispositional mindfulness relates to diet quality among midlife adults, an effect that may be explained in part by less depressive symptomatology. Given that lifestyle behaviors in midlife are leading determinants of risk for cardiovascular disease and neurocognitive impairment in late life, interventions to enhance mindfulness in midlife may mitigate disease risk. Additional research assessing the impact of mindfulness interventions on diet quality are warranted.

The legitimacy and safety of using alternative diets in cancer.

Alternative diets are used by cancer patients, especially among those who are not treated with conventional methods. Due to worrying data published by the World Health Organisation and its Agenda, the International Agency for Research on Cancer and the International Cancer Union, as well as epidemiological data from all over the world, it has been concluded that cancer will be the main cause of death in the world and that, therefore, the popularity of alternative diets among cancer patients may increase. The paper reviews the scientific literature and assesses the legitimacy and safety of selected alternative diets, as well as the description of research in terms of assumed anticancer efficacy in the following diets: ketogenic, Dr. Budwig and macrobiotic. The article also contains a summary of the analyzed scientific research and conclusions concerning the legitimacy of their use by cancer patients.

Development and validation of the Expanded Mindful Eating Scale.

PURPOSE: To develop and validate the Expanded Mindful Eating Scale (EMES), an expanded mindful eating model created for the promotion of health and sustainability. DESIGN/METHODOLOGY/APPROACH: A cross-sectional study using self-administered questionnaire surveys on Ochanomizu Health Study (OHS) was conducted. The survey was provided to 1,388 female university students in Tokyo, Japan. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and a partial correlation analysis were used to confirm construct and criterion validity. Internal consistency of the EMES was confirmed to calculate Cronbach's alpha. FINDINGS: The response rate was 38.7 % (n = 537). Mean BMI was 20.21 ± 2.12, and 18.8% of them were classified as "lean" (BMI < 18.5). The authors listed 25 items and obtained a final factor structure of five factors and 20 items, as a result of EFA. Through CFA, the authors obtained the following fit indices for a final model: GFI = 0.914, AGFI = 0.890, CFI = 0.870 and RMSEA = 0.061. The total EMES score was significantly correlated with BMI, mindfulness, body dissatisfaction, drive for thinness and life satisfaction (r = -0.138, -0.315, -0.339, -0.281 and 0.149, p < 0.01, respectively). Cronbach's alpha for all items in this scale was 0.687. PRACTICAL IMPLICATIONS: The authors suggest the possibility that practitioners and researchers of mindful eating that includes this new concept can use authors' novel scale as an effective measurement tool. ORIGINALITY/VALUE: The EMES, which can multidimensionally measure the concept of the expanded model of mindful eating was first developed in this study.

Maternal dietary diversity and dietary quality scores in relation to adverse birth outcomes in Tanzanian women.

BACKGROUND: Preterm birth (PTB), small for gestational age (SGA), and low birth weight (LBW) are risk factors for morbidity and mortality among infants. High-quality maternal diets during pregnancy may protect against these adverse birth outcomes. OBJECTIVES: The aim of this study was to prospectively examine the association of maternal dietary diversity and quality during pregnancy with birth outcomes among women in Dar es Salaam, Tanzania. METHODS: We analyzed data from 7553 HIV-negative pregnant women enrolled in a multivitamin trial at 12-27 weeks of gestation. Dietary intake was assessed using 24-h dietary recalls. Dietary diversity scores (DDS; range: 0-10) were computed as the number of food groups consumed by women, using FAO's Minimum Dietary Diversity for Women index. The Prime Diet Quality Score (PDQS; range: 0-42) assessed maternal diet quality based on consumption of 21 healthy and unhealthy food groups. Log binomial regression methods were used to assess associations of DDS and PDQS with PTB, SGA, LBW, and fetal loss. RESULTS: In the previous 24 h, 99.9% of all women had consumed cereal and staples, 57.9% meats, 4.7% eggs, and 0.5% nuts and seeds. Median DDS was 3.0 (IQR: 2.5-3.5). For the PDQS, all women consumed ≥4 servings/wk of green leafy vegetables and refined grains. Higher DDS was associated with lower risk of SGA (RR highest compared with lowest quintile: 0.74; 95% CI: 0.62, 0.89). Higher PDQS was associated with lower risk of PTB (RR highest compared with lowest quintile: 0.55; 95% CI: 0.46, 0.66), LBW (RR: 0.53; 95% CI: 0.40, 0.70), and fetal loss (RR: 0.53; 95% CI, 0.34, 0.82). CONCLUSIONS: PDQS was inversely associated with PTB, LBW, and fetal loss, and DDS was inversely associated with SGA. These findings suggest that in addition to dietary diversity, diet quality should be considered as important in understanding dietary risk factors for poor birth outcomes.This trial was registered at clinicaltrials.gov as NCT00197548.

UK Internet antenatal dietary advice: a content accuracy and readability analysis.

The aim of the study was to assess the accuracy and readability of Internet prenatal nutrition advice. Between August and December 2018, 130 Internet pages returned from Google searches on foods to avoid, foods to eat and supplements use were compared with UK government advice for pregnant women. Readability was assessed using the Flesch Readability Ease (FRE) tool. Descriptive and non-parametric tests were used. Spearman's correlation explored associations between accuracy and readability. Kruskal-Wallis tests with Bonferroni correction were used for multiple pairwise tests and Mann-Whitney U tests for two-sample differences in medians. A total of 130 Internet pages were examined: 48 % from publishers, 27 % from other commercial organisations, 22 % from charities and 3 % from governments. Eighty-three (64 %) pages contained inaccurate and accurate advice, twenty-three (18 %) were accurate and complete, twenty-one (16 %) were inaccurate, and three (2 %) lacked any relevant advice. The median percentage accuracy of all advice was 83 (lower quartile, upper quartile: 48, 100). Median FRE was 55 (46, 61) 'fairly difficult'. Eighty-seven pages (67 %) scored below the recommended FRE for public Internet pages. There was a weak positive correlation between accuracy and readability of Internet pages (rho = 0·241, P = 0·006). Accuracy of Internet pages did not differ by dietary theme. Pages on supplements were the most difficult to read. Internet pages from publishers and other commercial organisations were significantly less accurate than those from not-for-profit organisations (median percentage difference -8 (-29, 0·00), P = 0·019). Much pregnancy-related dietary advice online is inaccurate and difficult to read. Advice should be developed in consultation with qualified nutritionists and dietitians.

Dietary Diversity among Chinese Residents during the COVID-19 Outbreak and Its Associated Factors.

COVID-19, a Public Health Emergency of International Concern, has imposed enormous challenges on the health system, economy, and food supply and has substantially modified people's lifestyles. This study aimed to (1) explore the dietary diversity during the lockdown time in China and (2) examine factors associated with dietary diversity including socio-economic characteristics, sources for food and food purchases, and specific dietary behaviors responding to COVID-19 and isolation. A cross-sectional questionnaire-based survey was conducted online in March 2020. Multi-stage sampling was used to recruit participants living in Hubei Province and other parts of China. Dietary diversity was assessed using the Household Dietary Diversity Score (HDDS) and clustering analysis was used to categorize people with different propensities of methods for purchasing or obtaining foods. Logistic regression was used to model the associations among HDDS, participants' characteristics, approaches to purchase or obtain food, and behaviors adopted to cope with COVID-19. Results: A total of 1938 participants were included in the analysis. The overall mean HDDS was 9.7 ± 2.1, and the median (25th, 75th) was 10 (8, 12). There were relatively low consumptions of fish, legumes, and miscellaneous foods (e.g., processed food like snacks and beverages). After adjusting for age, family income, and geographic regions, people living in places where laboratory confirmed COVID-19 cases were above 500 (ORadjusted = 0.79, 95%CI 0.65, 0.96), or living in Hubei Province (ORadjusted = 0.60, 95%CI 0.39, 0.93) had a lower HDDS. During isolation time, the most common sources for food and food purchases were in-house storage and in person grocery shopping. More than half of the participants (55.9%) purchased food at least once via online ordering and delivery services. There was no significant difference in HDDS among people with distinct dependences on different ways to obtain or purchase food (i.e., dependence on in-person grocery shopping, dependence on both in-house storage and in-person grocery shopping, or dependence on online food purchasing). We also identified a total of 37.7% participants who consumed certain foods or nutritional supplements to cope with COVID-19, which included vitamin C, probiotics, other dietary supplements, alcohol, and vinegar. People who reported these specific dietary behaviors had a significantly higher HDDS (ORadjusted = 1.23, 95%CI 1.02, 1.45) than those who did not do so. This study revealed an overall good dietary diversity among the studied Chinese residents during the COVID-19 pandemic. However, we observed a lower dietary diversity among people living in areas with a high number of confirmed COVID-19 cases. Online ordering and delivery services were popular and could serve as a feasible method to obtain and purchase food, contributing to ensure diversified diets during the time of lockdown. Certain dietary behaviors associated with COVID-19 were also identified and had significant impacts on HDDS.

Toward standardized amino acid matrices for exogenous phytase and protease in corn-soybean meal-based diets for broilers.

A total of 468 male Ross 308 broilers were used in a digestibility study to determine the additivity of apparent or standardized amino acid (AA) digestibility values for corn, soybean meal (SBM), or a mixture of corn and SBM that were supplemented, or not, with either phytase, protease, or a combination of phytase and protease. These treatments generated a total of 12 experimental diets that were arranged in a 3 × 4 design. A nitrogen-free diet was also fed to estimate endogenous AA loss. Apparent and standardized AA digestibility values were assessed on day 28 posthatch. The apparent digestibility of AA in the complete diet was higher (P < 0.05) than expected based on the digestibility of the corn and SBM individually. However, this overestimation was corrected by the adjustment to standardized values. Importantly, addition of protease or the combination of protease and phytase increased (P < 0.05) the digestibility of AA in corn and SBM. Furthermore, these effects were arithmetically coherent with respect to the measured effects of the enzymes in the mixture of corn and SBM, even improving the additivity of AA digestibility values when assessed on an apparent basis. This study demonstrates that the effect of exogenous protease and phytase on AA digestibility in complete diets is predictable based on measurements made in individual ingredients. In addition to improving digestibility values per se, exogenous protease and phytase may enhance precision in least cost formulation systems.

Older adults with obesity have higher risks of some micronutrient inadequacies and lower overall dietary quality compared to peers with a healthy weight, National Health and Nutrition Examination Surveys (NHANES), 2011-2014.

OBJECTIVE: To evaluate total usual intakes and biomarkers of micronutrients, overall dietary quality and related health characteristics of US older adults who were overweight or obese compared with a healthy weight. DESIGN: Cross-sectional study. SETTING: Two 24-h dietary recalls, nutritional biomarkers and objective and subjective health characteristic data were analysed from the National Health and Nutrition Examination Survey 2011-2014. We used the National Cancer Institute method to estimate distributions of total usual intakes from foods and dietary supplements for eleven micronutrients of potential concern and the Healthy Eating Index (HEI)-2015 score. PARTICIPANTS: Older adults aged ≥60 years (n 2969) were categorised by sex and body weight status, using standard BMI categories. Underweight individuals (n 47) were excluded due to small sample size. RESULTS: A greater percentage of obese older adults compared with their healthy-weight counterparts was at risk of inadequate Mg (both sexes), Ca, vitamin B6 and vitamin D (women only) intakes. The proportion of those with serum 25-hydroxyvitamin D < 40 nmol/l was higher in obese (12 %) than in healthy-weight older women (6 %). Mean overall HEI-2015 scores were 8·6 (men) and 7·1 (women) points lower in obese than in healthy-weight older adults. In addition, compared with healthy-weight counterparts, obese older adults were more likely to self-report fair/poor health, use ≥ 5 medications and have limitations in activities of daily living and cardio-metabolic risk factors; and obese older women were more likely to be food-insecure and have depression. CONCLUSIONS: Our findings suggest that obesity may coexist with micronutrient inadequacy in older adults, especially among women.

Dietary taurine incorporation to high plant protein-based diets improved growth, biochemical, immunity, and antioxidants biomarkers of African catfish, Clarias gariepinus (B.).

Plant protein (PP) sources are generally used in high levels in fish diets. Mostly, PP sources are deficient in taurine; hence, there is a need for its supplementation to fish fed high PP diets. Therefore, effects of dietary taurine were examined on growth performance, feed utilization, immunity, and antioxidant parameters of African catfish, Clarias gariepinus (B.). Fish (10.3 ± 0.4 g) were fed on diets (40% crude protein) containing different taurine levels of 0 (control), 10, 20, 30, or 40 g/kg diet for 12 weeks. Fish fed a taurine-free diet (the control) with high PP sources showed poor growth as compared with these fed taurine-enriched diets where taurine stimulatory effects were observed on fish growth and feed intake. Feed conversion ratio and fish survival rate were not significantly differed among different treatments. Fish fed taurine-enriched diets showed also higher levels of serum glucose, cholesterol, total protein, albumin, globulin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, urea, and creatinine over that fed the control diet. Furthermore, lysozyme and respiratory burst activities as well as superoxide dismutase and catalase activities were significantly elevated in fish fed taurine-enriched diets (P < 0.05) and their highest levels were observed in fish fed 30 g/kg diet. Additionally, taurine deposition in fish muscles was positively correlated with dietary taurine levels (P < 0.05). The present study concludes that taurine is a limiting factor for growth, immunity, and antioxidants responses of African catfish fed high PP-based diets and it should be incorporated in its diets with an optimum level of 20 g/kg diet.

The Unfinished Agenda for Food Fortification in Low- and Middle-Income Countries: Quantifying Progress, Gaps and Potential Opportunities.

Large-scale food fortification (LSFF) is a cost-effective intervention that is widely implemented, but there is scope to further increase its potential. To identify gaps and opportunities, we first accessed the Global Fortification Data Exchange (GFDx) to identify countries that could benefit from new fortification programs. Second, we aggregated Fortification Assessment Coverage Toolkit (FACT) survey data from 16 countries to ascertain LSFF coverage and gaps therein. Third, we extended our narrative review to assess current innovations. We identified 84 countries as good candidates for new LSFF programs. FACT data revealed that the potential of oil/ghee and salt fortification is not being met due mainly to low coverage of adequately fortified foods (quality). Wheat, rice and maize flour fortification have similar quality issues combined with lower coverage of the fortifiable food at population-level (< 50%). A four-pronged strategy is needed to meet the unfinished agenda: first, establish new LSFF programs where warranted; second, systems innovations informed by implementation research to address coverage and quality gaps; third, advocacy to form new partnerships and resources, particularly with the private sector; and finally, exploration of new fortificants and vehicles (e.g. bouillon cubes; salt fortified with multiple nutrients) and other innovations that can address existing challenges.
