Development of food groupings to guide dietary advice in people with diabetes

Foods commonly consumed by 16 adults with diabetes were grouped according to macrinutrient value and type of fat to form 13 categories of which 10 would form the focus of dietary advice. Dietary modeling demonstrated that the food group pattern provided adequate nutrition and low variation in dietary targets. Idealised proportions of fat types were achieved only when daily servings of foods such as oils, nuts, oily fish and soy were included. The food groupings proved appropriate for dietary advice for diabetes

Systematic review of nutritional interventions for people admitted to hospital for alcohol withdrawal

Aim: The aim of this review is to describe the nature of nutritional interventions for people admitted to hospital for alcohol withdrawal reported in the scientific literature and the health outcomes achieved. Methods: The review protocol was registered with PROSPERO (CRD42017081884). The following databases were systematically searched following the PRISMA protocol: CINAHL, MEDLINE, PsycARTICLES, PsycINFO, Scopus and Web of Science. Eligible studies were those published in English, in a hospital inpatient setting with the primary reason for admission being alcohol withdrawal. Studies of patient populations with the diagnosis of pancreatitis or liver cirrhosis were excluded. Studies were screened for eligibility, and data were extracted and descriptively analysed. Identified articles were assessed using the Quality Criteria Checklist for Primary Research produced by the Academy of Nutrition and Dietetics. Results: Fourteen studies met the inclusion criteria. Given the heterogeneity of studies, only a descriptive analysis of interventions could be achieved. Nutrition interventions included supplementation with thiamine, multivitamins, amino acids, antioxidant compounds, probiotics, magnesium or were educational interventions. Outcome measures included memory function, biochemical and anthropometrical indices, withdrawal symptoms, bowel flora levels and nutrition knowledge. However, the overall body of evidence was limited, particularly as there was a wide variation in participant age, study designs and duration of interventions. Conclusions: A wide range of nutrition interventions were identified, mostly involving nutrient supplements ameliorating inadequacies. Future research might also consider total dietary interventions as well as studies on the perspectives of people undergoing alcohol withdrawal

Sorghum: An Underutilized Cereal Whole Grain with the Potential to Assist in the Prevention of Chronic Disease

Sorghum is an important cereal grain food, grown globally, that is rich in nutrients, dietary fiber, and bioactive components yet is considered of low value to humans and often used as an animal feed. This review provides an overview of key sorghum grain components, including starches, dietary fiber, protein, lipids, and phytochemicals, with functional properties that have potential to impact on health. Though acknowledging the impact of the whole food will reflect the synergy between the components, studies of these components implicate effects on energy balance, glycemic control, lipids, gut microbiota, and cell-mediated immune responses, including antioxidant and anti-inflammatory effects. For these to be confirmed as contributory effects from sorghum consumption, evidence from quality randomized controlled trials is required. If proven effective, there may be a role for sorghum grain–based diets to assist in the prevention of chronic diseases such as diabetes, obesity, and heart disease. Future research addressing effects of sorghum consumption may help drive a paradigm shift from sorghum as a low value food to a potentially health-promoting, highly valued human grain food

Using data mining to predict success in a weight loss trial

Background: Traditional methods for predicting weight loss success use regression approaches, which make the assumption that the relationships between the independent and dependent (or logit of the dependent) variable are linear. The aim of the present study was to investigate the relationship between common demographic and early weight loss variables to predict weight loss success at 12 months without making this assumption. Methods: Data mining methods (decision trees, generalised additive models and multivariate adaptive regression splines), in addition to logistic regression, were employed to predict: (i) weight loss success (defined as ≥5%) at the end of a 12-month dietary intervention using demographic variables [body mass index (BMI), sex and age]; percentage weight loss at 1 month; and (iii) the difference between actual and predicted weight loss using an energy balance model. The methods were compared by assessing model parsimony and the area under the curve (AUC). Results: The decision tree provided the most clinically useful model and had a good accuracy (AUC 0.720 95% confidence interval = 0.600-0.840). Percentage weight loss at 1 month (≥0.75%) was the strongest predictor for successful weight loss. Within those individuals losing ≥0.75%, individuals with a BMI (≥27 kg m-2) were more likely to be successful than those with a BMI between 25 and 27 kg m-2. Conclusions: Data mining methods can provide a more accurate way of assessing relationships when conventional assumptions are not met. In the present study, a decision tree provided the most parsimonious model. Given that early weight loss cannot be predicted before randomisation, incorporating this information into a post randomisation trial design may give better weight loss results

Changing social contracts in climate-change adaptation

Risks from extreme weather events are mediated through state, civil society and individual action 1 , 2 . We propose evolving social contracts as a primary mechanism by which adaptation to climate change proceeds. We use a natural experiment of policy and social contexts of the UK and Ireland affected by the same meteorological event and resultant flooding in November 2009. We analyse data from policy documents and from household surveys of 356 residents in western Ireland and northwest England. We find significant differences between perceptions of individual responsibility for protection across the jurisdictions and between perceptions of future risk from populations directly affected by flooding events. These explain differences in stated willingness to take individual adaptive actions when state support retrenches. We therefore show that expectations for state protection are critical in mediating impacts and promoting longer-term adaptation. We argue that making social contracts explicit may smooth pathways to effective and legitimate adaptation

Methodological framework for an integrated multi-scale vulnerability and resilience assessment

The deliverable illustrates the methodological framework to assess vulnerability and resilience across different temporal and spatial scales, acknowledging the different domains where the latter may manifest, and in particular in the natural and the built environment, allocating a large importance to the so called “critical infrastructures”, in social and economic systems. A set of four matrices has been developed to identify what aspects should be looked at before the impact, that is to say what shows the potential ability or inability to cope with an extreme; at the impact, addressing in particular the capacity (or incapacity) to sustain various types of stresses (in the form of acceleration, pressure, heat…); in the time immediately after the impact, as the ability (or inability) to suffer losses and still continue functioning; and in the longer term of recovery, as the capacity to find a new state of equilibrium in which the fragilities manifested during and after the impact are addressed. Developing the framework, a particular attention has been paid to the relationships among systems within the same matrix and among matrices, across spatial and temporal scales. A set of matrices has been developed for different natural hazards, including in particular landslides and floods, trying to include as much as possible what past cases, the international literature and prior experience of involved partners have indicated as relevant parameters and factors to look at. In this regard, the project builds on the state of the art, embedding what has been learned until now in terms of response capacity to a variety of stresses and in the meantime identifying gaps to be addressed by future research

Consumers' salient beliefs regarding dairy products in the functional food era: a qualitative study using concepts from the theory of planned behaviour

<p>Abstract</p> <p>Background</p> <p>Inadequate consumption of dairy products without appropriate dietary substitution may have deleterious health consequences. Social research reveals the factors that may impede compliance with dietary recommendations. This is particularly important given the recent introduction of functional dairy products. One of the challenges for public health professionals is to demonstrate the efficacy of nutrition education in improving attitudes toward nutrient rich foods. The aim of this study was to explore the salient beliefs of adult weight loss trial participants regarding both traditional and functional dairy products and to compare these with a control group not exposed to nutrition education.</p> <p>Methods</p> <p>Six focus groups were conducted, three with weight loss trial completers (<it>n </it>= 15) that had received nutrition education and three with individuals from the same region (<it>n </it>= 14) to act as controls. Transcribed focus groups were coded using the Theory of Planned Behaviour theoretical framework.</p> <p>Results</p> <p>Non-trial participants perceived dairy foods as weight inducing and were sceptical of functional dairy products. A lack of time/ability to decipher dairy food labels was also discussed by these individuals. In contrast trial participants discussed several health benefits related to dairy foods, practised label reading and were confident in their ability to incorporate dairy foods into their diet. Normative beliefs expressed were similar for both groups indicating that these were more static and less amenable to change through nutrition education than control and behavioural beliefs.</p> <p>Conclusions</p> <p>Nutrition education provided as a result of weight loss trial participation influenced behavioural and control beliefs relating to dairy products. This study provides a proof of concept indication that nutrition education may improve attitudes towards dairy products and may thus be an important target for public health campaigns seeking to increase intake of this food group.</p

Assessing the legitimacy of flood risk governance arrangements in Europe: insights from intra-country evaluations

Legitimacy has received comparatively less attention than societal resilience in the context of flooding, thus methods for assessing and monitoring the legitimacy of Flood Risk Governance Arrangements (FRGA) are noticeably lacking. This study attempts to address this gap by assessing the legitimacy of FRGAs in six European countries through cross-disciplinary and comparative research methods. On the basis of this assessment, recommendation
