Nut and legume consumption and human health: an umbrella review of observational studies.

Consumption of nuts and legumes has been associated with several health benefits. The aim of this study was to systematically review existing meta-analyses of observational studies on nut and legume intake and non-communicable diseases, and assess the level of evidence. Out of the six meta-analyses focussed on legume and 15 on nut intake, a possible association with decreased risk of colorectal adenoma and coronary heart disease was found for higher legume consumption, and a decreased risk of cardiovascular and cancer mortality, colon cancer, hypertension and ischaemic stroke for higher nut consumption.

Association between vitamin intake and respiratory complaints in adults from the UK National Diet and Nutrition Survey years 1-8.

Objective: To examine the cross-sectional association between vitamins A, E, C and D from diet and supplements and the prevalence of respiratory complaints in a nationally representative sample of UK adults.

Methods: Data from adult participants of the National Diet and Nutrition Survey Rolling Programme years 2008-2016 were used for the analysis. Logistic regression adapted for complex survey design was used to investigate the relationship between each vitamin intake in turn (exposure) and self-reported respiratory complaints (outcome), adjusting for relevant confounders.

Closing the gap: data-based decisions in food, nutrition and health systems: proceedings of the Fifth International Summit on Medical and Public Health Nutrition Education and Research.

Introduction: Like many of the biological sciences, nutrition has rapidly become a science which relies heavily on data collection, analysis and presentation. Knowledge gaps exist where data does not, and so the fifth annual International Summit on Medical and Public Health Nutrition Education and Research was held to address the theme of 'Closing the Gap: Data-based Decisions in Food, Nutrition and Health Systems'.

Setting: Homerton College, University of Cambridge, Cambridge in July 2019.

Connecting nutrition as a hard science and international knowledge networks: Proceedings of the Fourth International Summit on Medical and Public Health Nutrition Education and Research.

Introduction: Nutrition is a 'hard' science in two ways; the scientific rigour required for quality nutrition research, and equally, the challenges faced in evidence translation. Ways in which quality nutrition research can be synthesised and evidence effectively translated into practice were the focus of the Fourth Annual International Summit on Medical and Public Health Nutrition Education and Research.

Setting: Wolfson College, University of Cambridge, and Addenbrookes Hospital at the Cambridge Biomedical Campus, Cambridge, in July 2018.

Exploring the implications of COVID-19 on widening health inequalities and the emergence of nutrition insecurity through the lens of organisations involved with the emergency food response.

Background: This paper describes the impact of COVID-19 during the first month of containment measures on organisations involved in the emergency food response in one region of the UK and the emerging nutrition insecurity. This is more than eradicating hunger but considers availability of support and health services and the availability of appropriate foods to meet individual requirements. In particular, this paper considers those in rural communities, from lower socioeconomic groups or underlying health conditions.

Insights from a general practice service evaluation supporting a lower carbohydrate diet in patients with type 2 diabetes mellitus and prediabetes: a secondary analysis of routine clinic data including HbA1c, weight and prescribing over 6 years.

Background: In a single general practice (GP) surgery in England, there was an eightfold increase in the prevalence of type 2 diabetes (T2D) in three decades with 57 cases and 472 cases recorded in 1987 and 2018, respectively. This mirrors the growing burden of T2D on the health of populations round the world along with healthcare funding and provision more broadly. Emerging evidence suggests beneficial effects of carbohydrate-restricted diets on glycaemic control in T2D, but its impact in a 'real-world' primary care setting has not been fully evaluated.

Consensus-based nutrition care pathways for hospital-to-community transitions and older adults in primary and community care.

Background: Practical guidance for providers on preventing, detecting, and treating malnutrition in primary care (PC) and the community is limited. The purpose of this study was to develop nutrition care pathways for adult patients (aged ≥18 years) transitioning from hospital to community and community-dwelling older adults (aged ≥65 years) who are at risk for malnutrition.

Methods: A review of best-practice nutrition evidence and guidelines published between 2009 and 2019 was performed using PubMed and CINAHL.

Trends and Novel Research in Hospital Nutrition Care: A Narrative Review of Leading Clinical Nutrition Journals.

Hospital malnutrition is a longstanding problem that continues to be underrecognized and undertreated. The aim of this narrative review is to summarize novel, solution-focused, recent research or commentary to update providers on the prevention of iatrogenic malnutrition as well as the detection and treatment of hospital malnutrition. A narrative review was completed using the top 11 clinically relevant nutrition journals.

Dietary micronutrients in the wake of COVID-19: an appraisal of evidence with a focus on high-risk groups and preventative healthcare.

Existing micronutrient deficiencies, even if only a single micronutrient, can impair immune function and increase susceptibility to infectious disease. Certain population groups are more likely to have micronutrient deficiencies, while certain disease pathologies and treatment practices also exacerbate risk, meaning these groups tend to suffer increased morbidity and mortality from infectious diseases. Optimisation of overall nutritional status, including micronutrients, can be effective in reducing incidence of infectious disease.

Hidden curriculum within nutrition education in medical schools.

Introduction: Previous attempts to enhance medical nutrition education have typically focussed on students' acquiring nutrition knowledge or skills. Given that medical training uses an apprenticeship model of training, surprisingly few studies have explored the 'hidden curriculum' that students experience regarding expectations of behaviour, roles and responsibilities regarding nutrition. This study explored medical students' perceptions and experiences regarding medical nutrition education, focussing on the context in which nutrition teaching has been provided, the presented place of nutrition within medicine and their subsequent views on their role in providing nutrition care.

Investigation of Cardiovascular Health and Risk Factors Among the Diverse and Contemporary Population in London (the TOGETHER Study): Protocol for Linking Longitudinal Medical Records.

Background: Global trends in cardiovascular disease (CVD) exhibit considerable interregional and interethnic differences, which in turn affect long-term CVD risk across diverse populations. An in-depth understanding of the interplay between ethnicity, socioeconomic status, and CVD risk factors and mortality in a contemporaneous population is crucial to informing health policy and resource allocation aimed at mitigating long-term CVD risk. Generating bespoke large-scale and reliable data with sufficient numbers of events is expensive and time-consuming but can be circumvented through utilization and linkage of data routinely collected in electronic health records (EHR).

Whole grain intake compared with cereal fibre intake in association to CVD risk factors: a cross-sectional analysis of the National Diet and Nutrition Survey (UK).

Objective: To investigate how intakes of whole grains and cereal fibre were associated to risk factors for CVD in UK adults.

Design: Cross-sectional analyses examined associations between whole grain and cereal fibre intakes and adiposity measurements, serum lipid concentrations, C-reactive protein, systolic blood pressure, fasting glucose, HbA1c, homocysteine and a combined CVD relative risk score.

Setting: The National Diet and Nutrition Survey (NDNS) Rolling Programme 2008-2014.

Whole grain consumption and human health: an umbrella review of observational studies.

Whole grains have been associated with a number of health benefits. We systematically reviewed existing meta-analyses of observational studies and evaluated the level of evidence for their putative effects based on pre-selected criteria. Of the 23 included studies, we found convincing evidence of an inverse association between whole grain consumption and risk of type-2 diabetes and colorectal cancer; possible evidence of decreased risk of colon cancer and cardiovascular mortality with increased whole grain intake, as well as increased risk of prostate cancer.

The NNEdPro Global Centre for Nutrition and Health: A Consolidated Review of Global Efforts Towards Medical and Healthcare-Related Nutrition Education.

Whilst there is much focus on applying resources to generate evidence from human nutrition research, whether these involve experiment, observation or intervention, there is considerably little investment in the development and evaluation of effective approaches to apply the available knowledge base. Furthermore, when translating nutrition knowledge to the population at large, there are barriers to implementation, retention, and sustained impact, often due to largely unregulated public information on nutrition causing significant confusion and conflict. Healthcare professionals, therefore, have a key role in becoming reliable knowledge brokers, translating nutrition science to clinical or public health practice.

The association of dietary patterns and carotid intima-media thickness: A synthesis of current evidence.

Aims: Dietary pattern (DP) analysis has emerged as a holistic method to understand the effects of food intake on health outcomes. Though dietary intake has been associated with cardiovascular disease, the association of DPs and carotid intima-media thickness (CIMT), a robust early marker of cardiovascular disease progression has not been comprehensively investigated. This study systematically explores the association of a posteriori and a priori DPs and CIMT.

Day-Time Patterns of Carbohydrate Intake in Adults by Non-Parametric Multi-Level Latent Class Analysis-Results from the UK National Diet and Nutrition Survey (2008/09-2015/16).

This study aims at combining time and quantity of carbohydrate (CH) intake in the definition of eating patterns in UK adults and investigating the association of the derived patterns with type 2 diabetes (T2D). The National Diet and Nutrition Survey (NDNS) Rolling Program included 6155 adults in the UK. Time of the day was categorized into 7 pre-defined time slots: 6-9 am, 9-12 noon, 12-2 pm, 2-5 pm, 5-8 pm, 8-10 pm, and 10 pm-6 am.

Egg consumption and human health: an umbrella review of observational studies.

Egg consumption has been an area of controversy regarding its impact on human health largely due to the content in cholesterol and its potential role in cardio-metabolic outcomes. This study aimed to summarise the level of evidence of egg consumption on various health outcomes. A systematic search for meta-analyses was performed: study design, dose-response relationship, heterogeneity and agreement of results over time, and identification of potential confounding factors were considered to assess the level of evidence.

Dairy foods and health: an umbrella review of observational studies.

Evidence on consumption of dairy foods and human health is contradictory. This study aimed to summarize the level of evidence of dairy consumption on various health outcomes. A systematic search for meta-analyses was performed: study design, dose-response relationship, heterogeneity and agreement of results over time, and identification of potential confounding factors were considered to assess the level of evidence.

Dietary Polyphenol Intake, Blood Pressure, and Hypertension: A Systematic Review and Meta-Analysis of Observational Studies.

Background: Dietary polyphenols, including flavonoids, have been the focus of major recent attentions due to their wide content in a variety of foods commonly consumed and the findings from numerous studies showing evidence of an association with positive outcomes on human health.

Methods: A systematic search using electronic databases PubMed and EMBASE was performed to retrieve English language studies published from the earliest indexing year of each database to April 2019, reporting on the association between dietary flavonoids intake and hypertension.

Results: The search strategy resulted in the final selection of 20 studies including 15 cross-sectional investigations and 7 prospective cohorts (1 study reported on 3 prospective cohorts).

Nutrition Education and Community Pharmacy: A First Exploration of Current Attitudes and Practices in Northern Ireland.

Community pharmacist is one of the most prominent and accessible healthcare professions. The community pharmacists' role in healthcare is evolving, with opportunities being taken to reduce pressure on primary care services. However, the question remains of how well community pharmacists are equipped for this changing role.
