RESUMO

Only 6 to 8 % of the UK adults meet the daily recommendation for dietary fibre. Fava bean processing lead to vast amounts of high-fibre by-products such as hulls. Bean hull fortified bread was formulated to increase and diversify dietary fibre while reducing waste. This study assessed the bean hull: suitability as a source of dietary fibre; the systemic and microbial metabolism of its components and postprandial events following bean hull bread rolls. Nine healthy participants (53·9 ± 16·7 years) were recruited for a randomised controlled crossover study attending two 3 days intervention sessions, involving the consumption of two bread rolls per day (control or bean hull rolls). Blood and faecal samples were collected before and after each session and analysed for systemic and microbial metabolites of bread roll components using targeted LC-MS/MS and GC analysis. Satiety, gut hormones, glucose, insulin and gastric emptying biomarkers were also measured. Two bean hull rolls provided over 85 % of the daily recommendation for dietary fibre; but despite being a rich source of plant metabolites (P = 0·04 v. control bread), these had poor systemic bioavailability. Consumption of bean hull rolls for 3 days significantly increased plasma concentration of indole-3-propionic acid (P = 0·009) and decreased faecal concentration of putrescine (P = 0·035) and deoxycholic acid (P = 0·046). However, it had no effect on postprandial plasma gut hormones, bacterial composition and faecal short chain fatty acids amount. Therefore, bean hulls require further processing to improve their bioactives systemic availability and fibre fermentation.

RESUMO

BACKGROUND: One in four adults are estimated to be at medium to high risk of malnutrition when screened using the 'Malnutrition Universal Screening Tool' upon admission to hospital in the United Kingdom. The Need for Nutrition Education/Education Programme (NNEdPro) Group was developed to address this issue and the Nutrition Education and Leadership for Improved Clinical Outcomes (NELICO) is a project within this group.The objective of NELICO was to assess whether an intensive training intervention combining clinical and public health nutrition, organisational management and leadership strategies, could equip junior doctors to contribute to improvement in nutrition awareness among healthcare professionals in the National Health Service in England. METHODS: Three junior doctors were self-selected from the NNEdPro Group original training. Each junior doctor recruited three additional team members to attend an intensive training weekend incorporating nutrition, change management and leadership. This equipped them to run nutrition awareness weeks in their respective hospitals. Knowledge, attitudes and practices were evaluated at baseline as well as one and four months post-training as a quality assurance measure. The number and type of educational events held, pre-awareness week Online Hospital Survey results, attendance and qualitative feedback from training sessions, effectiveness of dissemination methods such as awareness stalls, Hospital Nutrition Attitude Survey results and overall feedback were also used to determine impact. RESULTS: When the weighted average score for knowledge, attitudes and practices at baseline was compared with four months post-intervention scores, there was a significant increase in the overall score (p = 0.03). All three hospital teams conducted an effective nutrition awareness week, as determined by qualitative data collected from interviews and feedback from educational sessions. CONCLUSION: The NELICO project and its resulting nutrition awareness weeks were considered innovative in terms of concept and content. It was considered useful, both for the junior doctors who showed improvement in their nutrition knowledge and reported enthusiasm and for the hospital setting, increasing awareness of clinical and public health nutrition among healthcare professionals. The NELICO project is one innovative method to promote nutrition awareness in tomorrow's doctors and shows they have the enthusiasm and drive to be nutrition champions.

RESUMO

Diets rich in fruits and vegetables have been correlated with decreased risks of cardiovascular disease. Particularly, berry consumption has been associated with reductions in cardiovascular risk. Despite the range of potentially beneficial phytochemical components (vitamins, polyphenols, carotenoids, and fatty acids), there is little evidence underpinning the cardiovascular effects of sea buckthorn (SB) berries. The purpose of this review is to evaluate the benefits of SB consumption on cardiovascular health in human trials. Only six human studies were found, which examine the effect of SB berries on cardiovascular outcomes (i.e., lipid metabolism, platelet aggregation, and inflammation). Although there appears to be an inverse association between SB consumption and cardiovascular risk factors, the evidence is still scarce and the results are inconsistent. In addition, limitations in study design made it difficult to form firm conclusions. More "high-quality" human clinical trials are needed in order to establish the cardio-protective benefits of SB berries.

RESUMO

SCOPE: Green leafy vegetables (GLV) may improve postprandial glycemic responses (PGR) and metabolic health. However, inter-individual variations (IIV) preclude conclusive evidence. Sirtuin system is emerging as a key player in blood glucose control. This study investigates IIV in PGR in women co-ingesting GLV with a carbohydrate meal and interactions with the sirtuin system. METHODS AND RESULTS: Volunteers (n = 31 women) consume rice, rice with bok choy, or spinach (75g available carbohydrate) on separate occasions. Postprandial glucose, insulin, adropin, and lipid levels are measured. Anthropometric measurements and sex hormones are measured. GeXP assay measures whole blood postprandial gene expression profiles of 25 markers involved in sirtuin signaling. GLV consumption has no significant effect on PGR, which shows high variation. PGR correlated with age, but no other consistent associations are observed. Sirtuin gene expression profiles reveal distinct stratified subgroups associated with PGR, lipid, insulin, fat mass, waist/hip circumferences, and adropin levels. CONCLUSION: PGR to co-ingesting GLV with a carbohydrate meal are highly variable in this cohort and fail to reveal a significant reduction in PGR. Variable responses are largely independent of menopausal status and meal consumed. However, lower expression of sirtuin gene targets is associated with higher PGR and with markers linked to health status.

RESUMO

BACKGROUND: In Kolkata (India), there are high rates of malnourished children (45.9%) under the age of three, impacting growth, organ development, function, and cognition. Mothers have a major role to play during this crucial development stage, with research showing nutrition knowledge, attitudes and practices (KAP) of mothers are important determinants of childhood malnutrition. AIMS: To document 3 years of capacity building towards a sustainable nutrition education network in Kolkata, India, while assessing the ability to perform data collection in the form of needs assessments, impact assessments and capacity reviews. METHODS: Descriptive review and analysis of engagement and impact from 3 years of work by the NNEdPro Global Centre for Nutrition and Health, initiating locally led nutrition education interventions. Mapping to the Indian National Nutrition Strategy was also performed to review adherence to nationwide priorities surrounding nutrition and determine the wider application potential of the network. RESULTS: Two simultaneous projects were taken forward by a team of local healthcare professionals and student champions. Project 1-medical college workshops for medical student nutrition education with added focus on underserved populations, Project 2-preparation for a 'Mobile Teaching Kitchen' (MTK) in marginalised communities to empower local women as nutrition educators.Data collection methods used for analysing markers of impact and sustainability were semi-structured interviews of the community members, and KAP questionnaires to assess response to educational sessions. CONCLUSION: With local support it is possible to create and sustain fieldwork for an extended period with meaningful outputs and impact. This initiative demonstrates that it is possible to use healthcare professionals, students and volunteers with low-intensity training and a low-cost approach to produce action research with considerable impact and results in rapid, reliable and robust manner.

RESUMO

BACKGROUND: Cardiovascular disease has a multifactorial aetiology with a number of both modifiable and non-modifiable risk factors. Although evidence indicates that dietary intake plays an important role, few studies have focused on the effect of fruit and vegetable consumption on early markers of vascular function. Therefore, we hypothesised that supplementation with capsules containing a combination of fruit and vegetable extracts over 12 weeks can significantly modulate biomarkers of vascular function compared with a control group receiving placebo. METHODS/DESIGN: This is a double-blind, randomised controlled trial that includes overweight and obese but otherwise healthy participants. Participants are randomly allocated to one of two groups: active supplementation (encapsulated fruit and vegetable powder) or placebo taken twice daily for 12 weeks, whereas both groups will be given the '5-A-Day' dietary advice. The primary outcome is to measure changes to the carotid intima media thickness (cIMT) between the two groups from baseline (test visit 1) to 12 weeks later (test visit 2). The secondary outcomes include macro- and microvascular changes and changes to blood markers. DISCUSSION: In addition to the primary and secondary objectives, this explanatory trial incorporates potential novel biomarkers such as trimethylamine-N-oxide (TMAO) and lipopolysaccharide (LPS). TRIAL REGISTRATION: ISRCTN14315618. Registration date 27 February 2014.
