The global COVID-19 pandemic has greatly accelerated the adoption of telehealth among clinical nutritionists. For instance, in the USA, telehealth usage for nutritional care has increased from 37% to 78% among clinical nutritionists <jats:sup>(3)</jats:sup>, while in Italy, the adoption of telenutrition services by Registered Dieticians (RDNs) has risen from 16% to 63% <jats:sup>(4)</jats:sup>. These statistics highlight the rapid integration of telehealth into dietetics practices as a response to the global health crisis, reflecting a growing trend towards virtual care delivery as an effective method for providing nutritional care. While telehealth has made progress in Saudi Arabia (5), there is a research gap regarding its prevalence and effectiveness in dietetics practice. This study aims to evaluate the current implementation of telehealth in dietetics practice during the COVID-19 pandemic in Saudi Arabia.In this cross-sectional, a web-based online survey was used from mid-December 2022 to mid-May 2023. The study was distributed in several Saudi Arabian regions including (central, western, eastern, south, and north) and was completed by 306 clinical Registered Dietitians (RDNs) in public and private healthcare facilities who met the study’s inclusion criteria. The survey consisted of 28 questions divided into four sections, covering sociodemographic information, past or current experiences, obstacles and challenges of telehealth usage, and the future prospects of telehealth. In this study, participants were requested to reflect on their current observations and previous experiences pertaining to the utilisation of telehealth in the field of dietetics. To ensure the validity and relevance of the survey, it was reviewed by a panel of experienced dietitians in Saudi Arabia to obtain their feedback before being used to collect data.Our research findings reveal that 76% of RDNs in Saudi Arabia utilize telehealth in their practice. The most common obstacles reported by RDNs using telehealth include internet connectivity issues (21.9%), patient disengagement and lack of enthusiasm (21.3%), and difficulties in coordinating with patients (21%). Telehealth interventions used by RDNs primarily involve diet recall (33.7%), weight- related measurements (30.6%), lab findings (26%), and only 8% reported using telehealth for vital signs. A majority of participants (69.4%) believed that telehealth could improve patient accessibility and help reduce no-show rates (68.9%). Additionally, over 70% of participants agreed that telehealth offers them flexibility in inpatient consultations.In conclusion, telehealth is widely utilised among RDNs in Saudi Arabia, with potential benefits such as decreased no-show rates.

Prisoners in general lack autonomy over their diet, in addition to being a population with a high risk of poor health outcomes<jats:sup>(2, 3)</jats:sup>. It is important therefore that prisons are offered menus which meet dietary reference values (DRVs), as set by the UK government, aiming for equity with the general population, and that prisoners choose food options that are beneficial for their health. The aim of this study was to conduct a nutritional analysis of prisoners’ food diaries to determine whether dietary recommendations were being met.Seven-day food diaries were collected from prisoners eating the normal food supplied by three young offender institutions in 2009. Food eaten was analysed using DietPlan6 version 6.0 (Forestfield Software Ltd). Individual nutrient data were tested for normality and compared against the UK DRVs and NDNS data from 2008/9 using either the one-sample T-test, or one-sample Wilcoxon Signed Rank Test. Data in the results is presented as (Mean ± SD).There were n=466 diaries analysed, from male participants aged between 16 to 24 years. Twenty- eight nutrients were compared with their respective DRVs by age categories: 16-18y (n=156), 19-24y (n=310), and 16-24y (n=466).For ages 16-24y, chloride (5556 ± 1692mg), folate (302 ± 112ug), iodine (195 ± 81ug), monounsaturated fat (35 ± 10g), potassium (3667 ± 1161mg), sodium (3899 ± 1392mg), sugar (136 ± 73g), riboflavin (2 ± 1mg), vitamin B<jats:sub>12</jats:sub> (6 ± 4ug), vitamin C (92 ± 63mg), and zinc (11 ± 3mg) exceeded DRV requirements (P&lt;0.01). Carbohydrates (53 ± 5%E), saturated fat (12 ± 5%E), and sugar (19 ± 9%E) all exceeded their DRVs (P&lt;0.05). Vitamin A (553 ± 531ug) and fibre (15 ± 6g) were found 24% and 18% lower than the DRVs, respectively (P&lt;0.01). Fat (34 ± 5%E), polyunsaturated fat (6 ± 1%E), and protein (14 ± 2%E), as a percent of energy, were below the DRV by 3%, 8%, and 7% respectively (P&lt;0.01). Magnesium (301 ± 107mg) was equal to the DRV (P=0.81).For 16-18, and 19-24 respectively, calcium (1286 ± 928mg; 1337 ± 489mg), copper (1 ± 0.6mg; 2 ± 0.6mg), iron (14 ± 5mg; 15 ± 6mg), niacin (19 ± 7mg; 21 ± 7mg), phosphorus (1545 ± 381mg; 1620 ± 493mg), protein (96 ± 24g; 100 ± 29g), thiamine (2 ± 0.6mg; 2 ± 0.7mg), and vitamin B<jats:sub>6</jats:sub> (2.3 ± 0.7ug; 3 ± 0.9ug) exceeded their DRV (P&lt;0.01).

Frailty was operationalised using a standardised frailty index (FI) of cumulative deficits from 33 variables across multiple health domains (physical, mental, comorbidities), with a score ≥0.25 indicating frailty. Cross-sectional associations between dietary nitrate derived from plant and animal foods (separately) with frailty were analysed using multivariable-adjusted logistic regression models as part of restricted cubic splines. Models were adjusted for lifestyle and dietary factors (not used in the FI) that included age, smoking history, protein, alcohol, and energy intake.Frailty was observed in 276 (19.9 %) women. Median (IQR) daily plant and animal nitrate were 72.1 (55.6-90.0) mg/day and 3.5 (2.2-5.1) mg/day, respectively. A significant non-linear relationship was observed between higher plant nitrate intake and frailty, with a nadir recorded once intakes of ~64 mg/day were achieved (median of quartile [Q]2). Specifically, compared to women with the lowest intake of plant-derived nitrate (Q1, median 45 mg/day), women in Q2 (OR 0.69 95%CI 0.56-0.84), Q3 (OR 0.67 95%CI 0.50-0.90) and Q4 (OR 0.66 95%CI 0.45-0.98) had lower odds for frailty (all p&lt;0.05). Additional adjustment for diet quality (Nutrient Rich Food Index per 1000 kJ) or total plasma 25-hydroxyvitamin D did not alter the findings. Nitrate derived specifically from vegetables and grains were found to drive these results. No relationship was observed between animal-derived nitrate and frailty.Community-dwelling older women consuming higher amounts of nitrate derived primarily from plants were less likely to present with frailty. Consuming 1-2 servings (75-150 g) per day of nitrate- rich green leafy vegetables, as part of total vegetable intake, will provide adequa","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":"23 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141527185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consumption of diverse plant-based foods is a dietary pattern that has gained significant attention amongst the public, due to its perceived benefits for maintenance of health&lt;jats:sup&gt;(1)&lt;/jats:sup&gt;. Plant-based foods provide a rich source of macronutrients, micronutrients and non-nutrient bio-actives that are often reported to improve health outcomes. Despite this, there are no standard definitions of plant-based diversity, or consensus on methods of measurement in nutrition research studies. The objective of the current research was to conduct a scoping review of the literature to identify studies investigating plant-based food diversity and it’s impact on human health outcomes, and to subsequently characterize a) definitions of plant-based diversity used, b) methods used to assess plant-based food intake, c) methods used to assess plant- based food diversity, and d) health outcomes assessed and key findings.Eligible studies were those investigating the relationship or impact of plant-based food diversity on any health related or lifestyle outcome, by any study design, in high income countries only. Studies were identified by systematic searches of two electronic databases and manual searches of reference lists. No restrictions were applied for language or year of publication. The review was performed in line with the guidelines for Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews &lt;jats:sup&gt;(2)&lt;/jats:sup&gt;.Forty-four studies were eligible for inclusion in this review. The majority of studies were observational in design (39/44; 87%) and included fruits and vegetables only in their definitions of plant-based food diversity (32/44, 72%). Methods of measurement of both plant-based food intake and diversity varied greatly among studies, with only four studies (9%) utilizing a tool validated for assessment of plant-based food diversity in their population of interest. Health outcomes included dietary intake and behaviour, socioeconomic factors, cardiometabolic risk factors, and cancer risk,. No randomized controlled trials investigating the impact of plant food diversity on health outcomes were identified.There is a need for a consensus definition of “diverse plant-based foods” incorporating all relevant foods from plant sources (e.g. legumes, nuts, herbs). Robust measurement tools and reporting guidelines for the assessment of plant-based food diversity in nutrition research studies will help to standardize research in this area. Within countries, an assessment of standard levels of intake of plant-based foods would be beneficial, in identifying whether diverse plant-based eating may be a target for dietary improvement.

This study aimed to investigate whether addition of β- glucan to energy and carbohydrate-restricted meals impacts postprandial responses of gastrointestinal appetite hormones and subjective appetite in overweight adults.Twenty-three sedentary individuals living with overweight or obesity (age: 36 ± 8.5 years, BMI: 31.12 ± 4.04 kg/m<jats:sup>2</jats:sup>) participated in a double-blind randomised crossover study with two experimental arms, each lasting over two days. On day 1, participants consumed Counterweight PRO800 meal replacement shakes/soups for breakfast and dinner at home, each providing ~200 kcal and a carbohydrate-restricted lunch providing 35% of their habitual energy intake. On day 2, participants attended the metabolic investigation room where they consumed the same breakfast and lunch as on day 1. On both days, each meal was taken with either 3g β-glucan (Oat Well) or cellulose (Comprecel) as placebo. On Day 2, fasting and postprandial appetite scores were recorded, and fasting and postprandial blood samples were obtained for the measurements of plasma concentration of acylated ghrelin, PYY, and GLP-1. The study is registered at www.clinicaltrials.gov as NCT05981404.Two-way ANOVA showed that the postprandial concentrations of acylated ghrelin (β-glucan arm, 383 ± 23 pg/ml; placebo arm, 428 ± 23 pg/ml, P=0.02, treatment effect) and composite appetite scores (P=0.003, treatment effect) were significantly lower and PYY concentrations (β-glucan arm, 132 ± 5 pg/ml; Placebo arm, 110 ± 4 pg/ml, P= 0.003, treatment effect) significantly higher in the β- glucan arm than in the Placebo arm. The concentrations of GLP-1 were not different between arms (β-glucan arm, 29 ± 1 pM; placebo arm, 28 ± 0.9 pM, P=0.36, treatment effect).The obtained data suggests that consuming β -glucan with energy and carbohydrate-restricted meals can be expected to attenuate reduction in satiety and diminish increase in hunger. Therefore, supplementation with β-glucan during energy restriction intervention applied to body weight loss might lead to improve compliance and reduce discomfort of negative energy balance.","PeriodicalId":20751,"journal":{"name":"Proceedings of the Nutrition Society","volume":"47 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141527218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
