Improved Understanding of Healthier Diets Grant Project Title Drivers of Eating Behaviour: chronic overconsumption Reference: homeostatic, hedonic, and biological markers BB/G005524/1 Investigator(s) Prof John Blundell and Dr Graham Finlayson Research Professor John Blundell (JB) has over 20 years experience of managing large scale Expertise research projects in the area of psychobiology of appetite control, energy balance, physical activity, nutrition and drugs as a Principle Investigator (PI). During a series of large scale projects funded by research councils, industry and EU, a high quality research infrastructure has been developed with an advanced methodological platform for the study of food, appetite, nutrition, exercise and energy balance. An interdisciplinary science base has been built up within a research culture of documented Good Laboratory Practice adn internationally recognized research. http://www.psyc.leeds.ac.uk/cgi-bin/10/people/index.pl?johneb Dr Graham Finlayson is a biological psychologist. His research is concerned with the interaction of hedonic and homeostatic systems that underpin human eating behaviour. http://www.psyc.leeds.ac.uk/cgi-bin/10/people/index.pl?grahamf Project This project was designed to uncover the way in which people eat, and their Overview susceptibility to overconsume during an extended and realistic challenge to energy balance. Because eating is part of a ‘complex’ system, we established a multi-level experimental platform based on a biopsychological systems approach. The platform was designed to monitor adaptive pressure on internal and external processes that drive appetite. Research studied obese participants undergoing long term physical activity and dietary challenges to uncover individual variability in positive energy balance – a ‘safe model of overconsumption’. Research monitored effects on homeostatic (hunger, meal size, EI) and hedonic (liking, wanting, food choice) markers of appetite in relation to changes in body composition, RMR and psychological traits. The project has also enabled the development of an innovative and comprehensive assay system to simultaneously monitor changes across all major plasma hormone biomarkers and metabolites. Industrial First demonstration that body composition and resting metabolism (RMR) are Impact fundamental drivers of homeostatic aspects of appetite (satiation and satiety) and in the presence of high energy dense foods, lead to overconsumption. A realistic criterion for overconsumption reflected in an objectively measured EI:RMR ratio establishes a benchmark for study of eating behaviour to identify associated homeostatic and hedonic mechanisms; and to cleanly test the effects of nutritional components on satiety. Action of ghrelin (‘hunger hormone’) understood through a distinctive 3 phase action on satiety (early and late stages) and satiation (control of meal size).Study outputs have implications for measuring the satiety impact of novel foods, and show that the process of satiety is complex and incorporates changes in the amount of food eaten, food choices, liking and wanting, and the temporal profile of GI hormones such as ghrelin. 5
Grant Project Title Understanding decisions about portion size: The key to acceptable Reference: foods that reduce energy intake? BB/G005443/1 Investigator(s) Dr Jeff Brunstrom, Prof Peter Rogers Research Dr Jeff Brunstrom and Professor Peter Rogers co-lead the Nutrition and Behaviour Expertise Unit, based in the School of Experimental Psychology at the University of Bristol. The unit is housed in a newly refurbished laboratory with extensive food-preparation facilities and the equipment and technical expertise to assess psychological and physiological responses to food. Currently, the Nutrition and Behaviour Unit accommodates the activities of four post-docs, four research assistants, and six Ph.D. students. Postgraduate students receive funding from a number of sources, including an ESRC competitive studentship, a BBSRC-DRINC award, a King Abdullah scholarship, a BBSRC-GSK industry-CASE award, a Cadbury-Great Western Research grant, and a BBSRC quota award. This ‘critical mass’ of researchers creates a highly stimulating and lively research environment. Our group meets on a weekly basis and interacts with other staff and students working in cognate research areas, such as addiction (primarily smoking and alcohol), psychopharmacology and genetics.The unit has considerable experience working with the food industry. Recent projects have focused on psychobiological controls of food intake and portion size, the psychopharmacology of caffeine, and effects of food on cognition and mood. In 2012 Brunstrom and Rogers will begin a 3-year BBSRC-LINK funded project exploring effects of eating behaviour on satiety. This work is co-funded by Nestlé. http://food.psy.bris.ac.uk/index.htm Project Researchers with an interest in energy intake tend to focus on 'amount eaten' or Overview self-reported hunger and fullness after a test food has been consumed. The logic here is that meal size is normally determined by psychological and physiological ‘events’ during and towards the end of a meal. This project aims to 1) challenge this fundamental assumption and 2) show how an understanding of portion-size decisions can help us to identify palatable foods that promote lower energy intake. Industrial Our research addresses the hypothesis that portion-size decisions are an important Impact determinant of energy intake. If this is the case (as we suspect), then it follows that by understanding how decisions are made we can design products that are both acceptable and which are expected to deliver maximum satiety. Products of this kind will promote reduced energy intake, because they will be selected and consequently consumed in smaller portions (in kcals). For the food industry, research of this kind could prove invaluable, especially in the development of effective 'diet' (e.g. low calorie) products. In particular, we anticipate two specific benefits the project will provide: 1. insight into specific foods and food characteristics that have high expected-satiation/satiety. 2. a methodology that can be used in-house to quantify expectations and beliefs about new and existing food products. These methods will be rigorously tested and will draw on cutting-edge techniques in psychometric assessment. 6
Grant Project Title Defining the gut-to-brain signalling mechanisms underlying Reference: responses to nutrients BB/G005591/1 Investigator(s) Prof John McLaughlin Research The Gastrointestinal Sciences Research Group is a multidisciplinary group of Expertise individuals bringing together clinical investigators, biological scientists and population researchers who are interested in the various aspects of science of the gastrointestinal tract. Our research encompasses a spectrum between basic molecular studies in epithelial biology and neuroscience, and clinical research including enteroendocrinology (the physiology of gut signalling peptides), neurogastroenterology (the control of gastrointestinal function via the enteric and central nervous systems) through to population based epidemiological studies and clinical trials. The team provide seamless transition from bench-to-bedside. Close collaboration with imaging science colleagues (Dr Shane McKie and Prof Steve Williams) are pivotal to current work, utilising physiological MRI scanning to study the effects of nutrient induced gut-to-brain signalling on human brain function. The regulation of appetite in health and disease is a key current focus. Currently the group are also working on establishing primary models of enteroendocrine cells for physiological study of nutrient sensing mechanisms, and exploring the interactions between the enteroendocrine cells and the immune system in gastrointestinal inflammation. http://www.medicine.manchester.ac.uk/gastrointestinal/research/ Project The key aim of the project is to understand the biological mechanisms by which Overview sugars and sweet tastants are sensed by the gastrointestinal tract and influence food intake, in particular via the enteroendocrine system. This is closely coupled to mapping the spatiotemporal matrix of activation in the human brainstem and other CNS areas by these nutrients, based on cutting edge imaging and analytical techniques developed in Manchester. This is permitting exploration of the gastrointestinal regulatory peptides secreted in response to nutrients in the regulation of gut-brain signalling, gastric emptying, and appetite. Industrial The health and prosperity of the population are under serious threat as a Impact consequence of overeating, and the resulting increase in the incidence of overweight and obesity. Understanding the mechanisms by which nutrients signal from the gut to the brain, and in particular how this influences appetite and food intake, are critical first steps to the development of novel satiating foods and beverages, and will also inform the complementary biomedical fields. 7
Grant Project Title Increased Propionate Production In The Colon Is Associated With Reference: Reduced Appetite, Body Weight And Improved Insulin Sensitivity BB/H00497/1 Investigator(s) Dr Gary Frost (ICL), Dr Douglas Morrison(SUERC), Dr Catriona Tedford (UWS) Research Imperial College London Expertise Nutrition and Dietetics Research Group The role of nutrients in appetite regulation and gut peptide release The role of carbohydrates in human health and disease The effect of body composition in human health and disease The clinical management of obesity and diabetes The role of nutrition in healthy aging http://www1.imperial.ac.uk/medicine/people/g.frost/ Scottish Universities Environmental Research Centre Stable Isotope Biochemistry Laboratory The role of environment on health and disease The design of colonic delivery systems The design of clinical studies using stable isotopes The analysis of 2H, 13C, 15N, 18O, 34S in biological samples from biomedical studies http://www.gla.ac.uk/research/az/suerc/ http://www.gla.ac.uk/research/az/suerc/ourstaff/morrisondouglas/ University of the West of Scotland The synthesis, purification and characterisation of modified carbohydrates http://www.uws.ac.uk/staffprofiledetail.aspx?id=2147486261&terms=tedford Project 1. To use a unique delivery system to increase colonic propionate production. Overview 2. To determine the effect of supplementing the diet of obese volunteers with the propionate carrier molecule change on appetite and body weight. 3. To investigate the effect of the propionate carrier molecule on the release of the anorexigenic gut hormones GLP-1 and PYY. 4. To investigate if increases in plasma propionate concentrations leads to a decrease in free fatty acid output from adipose tissue leading to improved insulin sensitivity. 5. To design foods which can be used to supplement the diet of the general population with the propionate carrier molecule. Industrial This work could provide a major benefit to the food industry. Few non-digestible Impact carbohydrates have been shown to have a significant or specific impact on propionate production. In this proposal research includes use of a propionate carrier molecule to deliver high levels of propionate to the large bowel. Should this work demonstrate the efficacy of propionate on appetite regulation, body composition and insulin sensitivity this could lead to the development of foods designed to increase propionate in the large bowel in ways acceptable to the consumer. 8
Grant Project Title Maximising satiety through manipulating expectations, sensory Reference: quality and nutrient content BB/H004645/1 Investigator(s) Prof Martin Yeomans Research The Ingestive Behaviour Unit in the School of Psychology at University of Sussex is Expertise a state-of-the art research facility for studying psychological influences on human ingestive behaviour, including facilities for preparation of novel test food and drinks, for analysing the microstructure of human ingestive behaviour using Sussex Ingestion Pattern Monitor (SIPM) technology (www.sipm.co.uk) and to allow testing of cognitive and affective changes relating to ingestion. These behavioural measures can be combined with more physiological assessments, including assay of appetite-related hormones, with additional facilities at Sussex for neuroimaging to allow evaluation of the neural basis of responses to food stimuli. Lead by Professor Yeomans, the Sussex Team currently comprises a full-time RF and 4 full-time DPhil students. Also associated with this project are facilities in the University of Brighton School of Service Management (Mr Harvey Ells, collaborator at University of Brighton). The Culinary Arts Studio is a research restaurant environment used both as a training space for the catering industry and a unique research space for studying human behaviour in a naturalistic environment. Sussex web-page: http://www.sussex.ac.uk/profiles/3030 Brighton web-page: http://www.culinaryartsstudio.co.uk/ Project The objectives detailed in the original proposal: Overview 1. Explore how expectations generated by labelling and sensory quality interact with protein content to generate satiety 2. Examine how labelling and sensory quality impact on physiological satiety responses 3. Test the effectiveness of prototypical high-satiety formulations on consumer behaviour in controlled intervention studies Industrial There is increasing demand from consumers for food and drink products that are Impact both enjoyable to consume but which also help prevent over-consumption. Thus optimal new products should be engineered to maximise satiety as well as flavour acceptability. As the experience of liking and satiety is influenced by product beliefs and sensory quality as well as nutrient content, industry needs design rules that allow them to integrate these different factors in an effective way to facilitate novel product development. The aims of this project are to provide evidence-based examples of how to integrate these components effectively. 9
Grant Project Title Reducing saturated fatty acids in the food chain through alteration Reference: of milk fat composition BB/1006087/1 Investigator(s) Prof Ian Givens Research The research team involved in this study is a combination of staff mainly from two Expertise departments at the University of Reading, namely the Division of Food Production and Quality and the Deptartment of Food and Nutritional Sciences. The team has nutrition-focused expertise across the food chain which includes a large food- producing animal research unit at one end and a state of the art human nutrition research unit at the other. Both departments have extensive laboratory facilities. The animal research unit is equipped with large animal calorimeters and thus the environmental aspects (e.g. methane output) of using animals as food producers can be measured. Animals’ diets can be tuned to produce, for example, milk with altered lipid profile and this can be used to make dairy products (cheese, butter, etc.) which can be used in human intervention studies to examine the effects on markers of chronic disease. In relation to the current project, the team has particular expertise on dietary lipids and vascular health with emphasis on the role fatty acids in bovine milk which exist as a highly complex mixture and include some unique trans and branched chain fatty acids. http://www.reading.ac.uk/apd/about/apd-stafffpq.aspx http://www.reading.ac.uk/food/ Project Overall objective: to reduce saturated fatty acids (SFA) entering the UK food chain Overview by targeting milk, with concomitant reduction in the environmental impact of milk production. Sub-objectives: To confirm that the milk fatty acid response to dietary change in large, commercial dairy herds with differing dietary backgrounds is consistent and of adequate magnitude. To explore the impact of dietary oilseeds and new rumen protection technology of fats on their ability to replace SFA by cis-MUFA/cis-PUFA without substantial accumulation of trans-MUFA, in association with an understanding of the dose- response of dietary oilseeds on methane production per litre of milk produced. To ensure that the project findings are successfully integrated and disseminated to various levels (industry, policy makers, health professionals, general public etc). Industrial Until this project, it was not known whether strategies to reduce saturated fatty acids Impact (SFA) in milk by changing the cow diet would provide sufficient changes when applied to commercial herds, as previous research has only been conducted in experimental situations. In addition, there may be means to sustainably reduce SFA to a greater extent than previously thought. This project is of huge benefit not only to members of the dairy food supply chain (from farm production through processor, retailer and the consumer) but also the food industry in general given that dairy products are present in a vast array of different foods. 10
Bioactives in Foods Grant Project Title Self-structuring foods with slow burn for control of satiety Reference: BB/G005478/1 Investigator(s) Prof Ian T Norton Research The Microstructure Group at the University of Birmingham led by Professor Norton Expertise carries out research into novel applications of foams, emulsions and gels for the formulation of healthy foods to combat obesity. The Group runs research projects that aim to reduce the energy density of foods, maintain sensory acceptability and hedonic rating, and increase their satiety. The Microstructure Laboratory (MSL) develops inventive techniques for designing interfacial and surface properties of food gels and emulsions, the latter with feature sizes ranging from nano/micrometers, and uses these structures in a range of research projects. The MSL includes facilities for processing (microfluidizer, impinging jet, homogenisers, membrane emulsification, and pin stirrer heat exchangers), thermoanalysis, polarimetry, spectroscopy, microscopy (light, confocal and electron microscopy), assessment of material properties (rheological, fracture, lubrication and interfacial) and a food sensory assessment laboratory. Much of the emulsification equipment, and methods, utilized in the MSL are developed in-house. The research projects within the MSL fall into three closely interlinked major categories: process development (emulsification, gelation and encapsulation), formulation process design (colloidal particles at interfaces, material properties) and in-use properties (oral properties and cooking behaviour). http://www.birmingham.ac.uk/research/activity/chemical-engineering/index.aspx Project The overall aim of our project has been to formulate a variety of novel liquid, soft Overview solid and semi-soft solid (paste-like) foods that are enjoyable to eat and that are also capable of responding to the body's natural processes of digestion in the stomach by self-structuring and slowly releasing nutrients. Such foods would have a major impact on the obesity problem because they would potentially control satiety. Industrial Based on the project findings the research team propose that it is possible to Impact successfully gel (structure) acid-sensitive solutions at pH values found in the stomach and to break (de-structure) the resulting gels within a desired time frame by forces typically found in the stomach. It is also feasible to improve the performance of these gels by adding other components. These can include other hydrocolloids, ingredients that release energy (i.e. oil, starch and proteins), nutrients, colours and flavours. Ingredients could be encapsulated in hydrocolloid shells for controlled release at various stages within the gastrointestinal tract. Instead of simple oil-in- water emulsions, double emulsions could be trapped within the gel network. There are endless possibilities for inclusion of more complex structures. 11
Grant Project Title The role of plant cell walls in regulating starch and lipid Reference: bioaccessibility from plant foods: in silico, in vitro and in vivo BB/H004866/1 studies. BB/H004874/1 Investigator (s) Dr Peter Ellis (KCL), Prof Keith Waldron (IFR) and Dr Peter Butterworth (KCL) Research King’s College London: Expertise in the behaviour of edible plant polysaccharides Expertise (cell wall polymers and starch) in the gastrointestinal tract, and also in the amylolysis (hydrolysis of starch by amylase), analysis and characterisation of starches. Human intervention studies of postprandial metabolism, and the relationship between diet and cardiovascular disease. The consultant gastroenterologist who is part of the team regularly carries out studies using ileostomy patient volunteers. http://tinyurl.com/crxzz5a IFR: The two groups involved at IFR have expertise in plant cell wall structure and biochemistry, colloid chemistry, gastrointestinal tract physiology and digestion modelling. IFR also houses the Dynamic Gastric Model, a physiologically relevant in vitro model of digestion which simulates the human stomach. http://www.ifr.ac.uk/info/science/exploitation/sustainability.htm Imperial College: Expertise in the effects of diet on postprandial metabolism, insulin resistance and gut hormone responses. Also carrying out novel investigations of the effects of fermentable carbohydrates on appetite centres in the hypothalamus. Project 1. Characterisation of raw, processed and masticated plant foods rich in lipid and Overview starch. 2. Establish degree of penetration of plant cell walls (PCW) by lipases and amylases and subsequent hydrolysis of intra-cellular lipid and starch. 3. Determine the rate and extent of lipid and starch digestion of plant foods in vitro & in vivo. 4. Develop mathematical/kinetic models for predicting bioaccessibility of lipid and starch. 5. Identify the mechanisms by which PCW influence nutrient release and digestion kinetics. Industrial Modelling starch digestion kinetics has highlighted for the first time three structure- Impact related stages of amylase hydrolysis (fast, medium and ‘resistant’), and has implications for controlling Glycaemic index, satiety, distal nutrient delivery and large bowel health. Modelling lipid bioaccessibility has implications for developing dietary and recipe- based approaches for modulating nutrient delivery with potential beneficial impacts on weight management, satiety and plasma lipid profile. Both models could inform strategies for the rational processing of plant-based ingredients to optimise health benefits. 12
Grant Project Title Mining diversity in cereal (wheat) fibre to improve the Reference: nutritional quality of bread BB/I006079/1 Investigator(s) Prof Peter Fryer, Prof Clare Mills and Prof Peter Shewry Research The team combines expertise in : Expertise (i) Food engineering at Birmingham (Peter Fryer, Serafim Bakalis, Bostjan Hari)) (ii) Food science and biochemistry at IFR and Manchester (Clare Mills, Geraldine Toole) (iii) Plant Science at Rothamsted (Peter Shewry) (iv) Baking at Campden BRI (Frank Gates) (v) Digestion at IFR and Leatherhead (Martin Wickham and Giusy Mandaleri) The project will construct in vitro and computational models for digestion and study how bread is digested; methods developed will be used to examine breads with different fibre compositions are broken down and digested, with the aim of identifying the chemical and physical effects of fibre. http://www.birmingham.ac.uk/staff/profiles/chemical-engineering/fryer-peter.aspx http://www.ifr.ac.uk/profile/clare-mills.asp http://www.medicine.manchester.ac.uk/staff/156334 http://www.rothamsted.ac.uk/PersonDetails.php?Who=137299 Project Bread is a staple food in the UK diet with a high glycaemic index (GI). Any reduction Overview in GI is likely to make a significant contribution to promoting the health on the nation, low GI foods being protective against conditions such as type 2 diabetes. However, we currently lack the understanding and tools to modify the GI of bread in a knowledge-based way. This project unites plant scientists, food scientists and engineers to build fundamental understanding of how natural variation in the composition and solubility of the fibre fraction (specifically arabinoxylan (AX)) of wheat endosperm cell walls is modulated by processing and digestion. Industrial The aim of the project is to study how breads with different fibre contents are Impact digested and identify how the effects of changing the composition and solubility of the fibre fraction might affect digestion and thus GI. The work could lead to better understanding of the digestion of fibre and aid in the formulation of breads with health benefits. 13
Grant Project Title Ergocalciferol (Vitamin D2) vs. Cholecalciferol (Vitamin D3) Food Reference: Fortification: Comparative Efficiency in Raising 25OHD Status in BB/I006192/1 Caucasian & Asian Women and Mechanisms of Action Investigator(s) Prof Susan Lanham-New Research The research group behind the D2-D3 study offer a range of expertise within the Expertise area of nutritional sciences, food product development and functional genomics combining to form a team capable of completing complex physiological and mechanistic studies that are vital in establishing the role of nutrition in maintaining health. Professor Susan Lanham-New, Dr Elina Hypponen and Dr Jacqueline Berry are world-leading experts within the field of vitamin D research, specialising respectively in the role of vitamin D in bone health and the development of highly-specialised assays for the accurate detection of vitamin D within biological samples. Dr Laura Tripkovic and Dr Kathryn Hart are both registered dietitians with many years experience in managing nutrition-based clinical trials, with roles as varied as participant recruitment, biological sample processing and dietary analysis. Dr Simon Penson and Dr Gemma Chope provide vital industrial expertise in food product development, particularly food fortification. Professor Colin Smith and Dr Giselda Bucca are world-leading experts within the field of functional genomics, with special consideration for the associations between genetic predisposition to health conditions and the impact that nutritional intervention/status may have on ameliorating risk. http://www.fhms.surrey.ac.uk/nutritionandbone/index.php Project The D2-D3 study (a food fortification intervention trial) has primarily been set-up to Overview compare the efficacy of 15µg/d [600IU/d] vitamin D2 vs. 15µg/d vitamin D3 in raising serum 25(OH)D levels in both caucasian and south asian women above the ‘deficiency/insufficiency’ thresholds (25nmol/l and 40nmol/l respectively) during the winter months. The mechanism behind any vitamin D effects will be investigated via enzymatic and genetic analysis. Industrial Information on the comparative effectiveness of the two different forms of vitamin D Impact as food fortificants in raising 25OHD levels in UK populations with known ‘insufficiency’ (caucasian) and ‘deficiency’ (south asian) will prove invaluable to the food manufacturing industry. This study also presents an excellent opportunity to elucidate whether the food vehicles used in the study (a juice and a biscuit) are appropriate in terms of both acceptability to the study population and the stability of the vitamin D in the respective food vehicles. 14
Grant Project Title Enhancing the consumer perception of reduced fat foods Reference: through interfacial design and rheological behaviour BB/I006168/1 Investigator (s) Prof Peter Wilde (IFR) and Dr Paul Clegg (Edinburgh) Research IFR: The food structure team’s focus is the physical chemistry of food structure, Expertise specifically colloidal and interfacial behaviour in emulsions and foams pertinent to food. Molecular and intermolecular processes (mainly proteins) which control adsorption to interfaces, interfacial structure and physical properties which control overall emulsion functionality (structure, rheology, digestibility, etc). Methodologies include interfacial tension, interfacial rheology, bulk rheology, atomic force microscopy, light microscopy, light scattering / particle analysis. http://www.ifr.ac.uk/info/science/Food-and-Health/index.htm#structure University of Edinburgh: The soft matter team’s focus is on the formation, organisation and flow properties of emulsions. We prepare model emulsions that can be imaged using confocal microscopy and whose flow properties can be characterised using standard rheological techniques. Our cutting edge capability is a facility for combining simultaneous imaging and rheology in, so called, rheo-imaging experiments. This allows us to relate microscopic changes to bulk properties. We have an interest in stabilising emulsions using colloidal particles alone. http://www2.ph.ed.ac.uk/cmatter/soft.html Leatherhead Food Research: The sensory research team has extensive experience in sensory and consumer research. They have a dedicated screened- and-trained panel and a large consumer database which allows in-depth consumer awareness studies. Methods include sensory perception, consumer insight, product benchmarking and preference mapping. http://www.leatherheadfood.com/sensory-and-consumer Project The overall aim of the project is to determine the fundamental colloidal mechanisms Overview by which the interfacial layer of emulsion droplets can be manipulated to control the structure and rheology of emulsified foods in order to improve the organoleptic properties and consumer preference of reduced fat foods. Industrial The outputs of the project will be a set of design rules which food manufacturers can Impact use to create emulsified foods with improved sensory quality in terms of perception of fat content. The aim is that these strategies can be applied to reduced fat foods which have poor perceived quality, and thus increase their uptake by consumers. This approach should also reduce the need for adding other ingredients such as starch, salt and sugar, which are often added to improve the sensory quality of low fat foods, but reduces nutritional impact, this approach will therefore result in real improvements in the nutritional quality of the foods, and savings in raw materials costs. 15
Grant Project Title The Collective Bioactivity of Dietary Flavonoids: Specific Structural Reference: Characteristics and Cardiovascular Disease BB/I006028/1 Investigator(s) Dr Colin Kay Research Dr Colin Kay (UEA) is a leading expert in anthocyanin research. His research Expertise focuses on the degradation, metabolism and bioactivity of anthocyanins in vivo and in vitro.

This collaboration has provided the project with access to state of the art cell culture and laboratory facilities, including HPLC/MSMS equipment, and access to an extensive variety of biochemical and molecular biology resources. http://www.uea.ac.uk/med/People/Academic/Colin+Kay#research Dr Qinzhi Zhang is a senior post doctoral researcher in the School of Chemistry, University of St Andrews, with expertise in the chemical synthesis of phytochemicals and their metabolites. http://www.st-andrews.ac.uk/chemistry/ Dr Jason Kerr is a post doctoral researcher and has extensive experience of in vitro assay design, culture of mammalian cell types, and molecular biology techniques. http://www.uea.ac.uk/pha/moc Project Numerous studies have indicated that the consumption of flavonoids is associated Overview with a lower incidence of cardiovascular disease (CVD) and associated mortality. This project has selected the most commonly consumed flavonoid species in the UK diet, their immediate degradation products, and metabolic by-products in order to assess their cardioprotective activities. Compound efficacy as cardioprotective phytochemicals will be assessed in isolation and in combinational treatments, designed to mimic typical dietary consumption. The effectiveness of dietary flavonoids to reduce the detrimental effects associated with the onset of CVD conditions will be assessed by monitoring their activity on inflammatory cytokine expression, vascular reactivity, and the regulation of transcription factors related to the development of CVD. Data generated from this study will make it possible to infer the structural characteristics associated with the beneficial health effects of flavonoids. It will also provide insight to whether these flavonoids work in isolation, or if, as in typical consumption (in combination), exert their beneficial effects in a collective manner. Industrial Flavonoids are present in a plethora of foodstuffs consumed everyday in the UK The Impact identification of specific flavonoids, and combinations of flavonoids, within these foodstuffs that act as cardioprotective phytochemicals will help identify targets (compounds, doses, and clinical endpoints) for future intervention studies required to establish health claims. 16

Grant Project Title The effect of dietary bioactive compounds on skin health in Reference: humans in vivo BB/G005575/51 Investigator(s) Prof Lesley Rhodes (Manchester), Prof Anna Nicolaou (Bradford), and Prof Gary Williamson (Leeds) Research Manchester: Expertise in examining inflammatory responses in human skin, Expertise specifically the acute UV response, longer-term photodamage, and systemic photoprotective measures, particularly nutrition. Techniques include UV application to human skin and skin cells in vivo and in vitro, assessment and dose-response modelling of erythema, skin sampling, immunoassay and immunohistochemistry. www.medicine.manchester.ac.uk/staff/lesleyrhodes Bradford: Expertise in biological chemistry and analytics with emphasis on small molecule bioactivity, eicosanoid mediators of inflammation, and pharmaceuticals with laboratories appropriate for analysis of clinical samples. www.skin.brad.ac.uk/people/anna-nicolaou/ Leeds: Expertise in polyphenol absorption and metabolism including extraction techniques and HPLC methods for measurement of polyphenols in biological fluids (cells, culture medium, blood, urine) and food. www.food.leeds.ac.uk/People/Williamson.html Project There is little information on the effect of oral catechin, a nutritionally relevant Overview bioactive compound, on skin health in humans in vivo, despite considerable evidence for protective effects, including against UV stresses, in experimental studies. Vitamin C is essential for skin health, and also stabilises catechins in the gut lumen. Ultraviolet radiation in sunlight is a key environmental stressor impacting on skin health, effects including acute inflammation and longer-term photodamage. Research will examine protection by a combination of dietary catechin and vitamin C on UV-induced inflammation, through a randomised controlled double-blind study. Specifically, research will examine for skin erythema, leucocytic infiltration, and for molecular mediators of these processes in samples of skin and skin fluid. Research will determine bioavailability of catechin and levels of UV protection. Further, skin samples taken will also be used to assess for immunohistochemical evidence of protection against UV-induced DNA damage and changes in MMP-1, fibrillin-1 and pro-collagen-1, in a short–term model of photoageing. Overall, this project will establish efficacy of bioactives against UV- inflammation, the oral and skin nutrient levels required, and indicate potential against longer-term skin damage. Industrial Catechins are a group of dietary bioactive compounds found as components of Impact green tea and other beverages advertised for their ‘protective’ properties. Thus, our study will offer scientific justification and advice for the correct utilisation/ administration/dosage of catechins in promotion of skin health and protection from short and longer-term damaging effects of sunlight. Data gained from our study objectives will aid industry to formulate preparations and/or fortify foods and assist their claims for beneficial properties. 19
Project Title Effects of Fruit Juice Processing and Human Metabolism Grant on the Functionality of Anthocyanins for Cardiovascular Reference: Health BB/H004963/1 Principal Investigator Dr Colin D Kay(UEA) and Dr Paul Kroon(IFR) Research This project is undertaken through a collaboration between the University of East Expertise Anglia (UEA), Institute of Food Research (IFR) and The University of St. Andrews and has brought together expertise in synthetic chemistry, conducting human feeding studies, bioanalytical mass spectrometry and molecular biology. Dr Colin Kay (Senior lecturer) is a leading expert in anthocyanin research and investigating the bioactivity of anthocyanins and their metabolites. Prof. Aedin Cassidy (UEA) has worked in the phytochemical field for over 20 years and is an expert on the health effects of the flavonoids. Dr. Charles Czank is the PDRA for the DRINC project and coordinates all aspects of the human feeding study, analyses of clinical samples and bioactivity studies. http://www.uea.ac.uk/med/People/Academic/Colin+Kay#research Dr. Paul Kroon (IFR) is an expert on polyphenol bioavailability and the effects of metabolism on biological activity. http://www.ifr.ac.uk/profile/paul-kroon.asp The synthesis of the feeding study compound was undertaken at University of St. Andrews by Dr. Qingzhi Zhang (PDRA) in the School of Chemistry. http://www.st-andrews.ac.uk/chemistry/ Project Available data suggests that consumption of anthocyanins (ACN) such as cyanidin- Overview 3-glucoside (C3G) may be protective against cardiovascular disease (CVD). However, ACN bioavailability is perceived to be low and given that they are prone to degradation during commercial processing, storage and following ingestion, their degradation products and metabolites are likely to contribute to their bioactivity. This hypothesis is being explored using a combination of synthetic chemistry, studies of fruit processing and storage, a stable isotope metabolism study in humans and the evaluation of metabolite bioactivity using cell culture models. Industrial As berry juices are the most commonly available vehicle for the delivery of Impact anthocyanins to the consumer, it will be determined if processing leads to degradation of anthocyanins or other structural changes that may affect their bioactivity. There is also little known about what happens to anthocyanins once they are consumed and what bioactive forms of the parent compound contribute to prevention of CVD. The findings of this study will provide evidence to form the basis of future studies that are necessary to establish health claims for anthocyanins. 20
Grant Project Title Dietary polyphenols as modulators of redox signalling pathways to Reference: reduce chronic inflammation in the elderly BB/I005994/1 Investigator(s) Prof Malcolm J. Jackson Research The Musculoskeletal Biology group at the University of Liverpool has a long track Expertise record of research on nutrition, redox signalling, and the biology of muscle in ageing, with broad expertise in cell, animal, and human studies.

Provide polyphenol-enriched foodstuffs to volunteers aged 80 years and over to identify polyphenols capable of reversing changes in thiol redox and cytokine release observed with ageing. Industrial The project will identify and validate polyphenols as dietary supplements to reduce Impact markers of inflammation in ageing. Reduced inflammation is correlated with better general health and reduced disease risk. Polyphenols which research identifies as anti-inflammatory could be used as supplements for dietary products e.g. yoghurts, drinks etc., with validated health claims. Researchers are working with Unilever on this project. 21
Grant Project Title Immunomodulatory effects of pre- and probiotics Reference: BB/H00570X/1 Investigator(s) Prof Parveen Yaqoob (Reading) and Prof Richard Aspinall (Cranfield) Research The project is led by Prof Parveen Yaqoob, who has expertise in nutrition, immune Expertise function and inflammation and has conducted a number of large human intervention studies, combined with cellular analysis of immune function. Microbiology expertise is provided by Professor Ian Rowland and Dr Kieran Tuohy, and clinical expertise is provided by Professor Margot Gosney, who is Professor of Geriatric Medicine at the Royal Berkshire Hospital. Professor Sue Todd completes the investigator team at Reading as our statistician. Dr Caroline Childs as PDRA employed on the grant manages the project, drafting the ethics application/protocols, overseeing data collection and statistical analysis of the primary outcome data. She is currently leading the analysis of immune function, using cells which were cryopreserved during the intervention. Dr Catherine Maidens and Miss Agnieszka Przemska recruited the subjects, ran the intervention study and performed laboratory analyses, supported by a research nurse, Dr Esme Roads, who screened the subjects and performed the vaccinations. www.reading.ac.uk/nutrition Prof Richard Aspinall is a collaborator at Cranfield University. http://www.cranfield.ac.uk/health/abouttheschool/people/page23479.html Project Ageing results in a decline in immune function, resulting in greater susceptibility to Overview infection, particularly respiratory infection, and a poor response to vaccination. Evidence suggests that pre- and probiotics may enhance immune function and act as adjuvants to vaccination. The aim of this study was to investigate the effects of a novel probiotic and prebiotic mixture (synbiotic) consisting of 5x108 CFU of Bifidobacterium longum bv. infantis CCUG 52486 and 8g of glucooligosaccharide (GIOS), on the immune response to influenza vaccination in young and older subjects. Statistical analysis will evaluate prognostic factors determining the efficacy of the response to vaccination, and whether the response to the synbiotic is influenced by an ageing immune system. Industrial Marketing of products containing pre- and probiotics is based on benefits for gut Impact health and immune defences. EFSA have indicated that robust data showing improvement of the efficacy of vaccination may be permissible as evidence for claims relating to immune function. This research has successfully completed such a study using a novel, non-commercialised symbiotic developing methodology that could be applied to test the adjuvant properties of any product with respect to vaccination. Importantly, we are using cells cryopreserved during the intervention to conduct detailed immunological analysis to understand the mechanisms underlying the influence of pre- and probiotics on immune function in the context of ageing. 22

To this end, the objective was to undertake a randomised controlled trial (RCT) to assess the impact of non-digestible carbohydrates, Resistant Starch (RS) and Polydextrose (PD) on i) biomarkers of CRC risk, ii) fermentation in the large bowel and iii) immune function. This study also aims to develop a biobank of samples and metadata and provide a model for future studies of diet and large bowel function and health. Industrial Successfully demonstrating that biomarkers of CRC risk respond to dietary Impact intervention with RS and PD would provide a model system by which future novel biomarkers could be screened. Furthermore, a panel of nutrition-responsive biomarkers will offer industry robust surrogate endpoints against which other foods and dietary components could be tested for potential health benefits in the large bowel and could be used potentially to support health claims. 23
Grant Project Title Unravelling the mechanisms of vascular protection by omega-3 Reference: PUFAs to optimise and support their use as bioactives by the food BB/I005862/1 industry Investigator(s) Prof Caroline Wheeler-Jones Research Caroline was appointed to a lectureship position at the RVC in late 1997 and Expertise now holds a Chair in Vascular Cell Biology. She is currently co-ordinator of the lifestyle research programme with major research interest in endothelial cell signalling. Her research group is investigating the molecular mechanisms important for regulating pro- and anti-inflammatory gene expression and downstream cellular functions in response to a range of external stimuli, including ligands for G protein-coupled receptors and growth factor receptors, and exogenous lipoproteins. The group uses in vitro, ex vivo and in vivo cell and molecular approaches to delineate the signalling pathways controlling gene expression and functional responses of human and murine large vessel and microvascular endothelial cells. http://www.rvc.ac.uk/Staff/cwheeler.cfm Project Chylomicron remnants (CR) are small lipoproteins present in the blood 3-9 hours Overview after a meal in healthy individuals. Whilst CRs are rapidly cleared from the blood by the liver in healthy individuals, CR circulation time is prolonged in individuals with diabetes, renal failure and familial hyperlipemia and there is mounting evidence linking CRs to endothelial dysfunction and atherosclerosis. Although a number of beneficial health effects have been proposed for omega-3 polyunsaturated fatty acids (ω -3 PUFAs) in vivo evidence for efficacy and knowledge of the underlying mechanism(s) of action are currently lacking. The aim of this project is to test the overarching hypothesis that, in the postprandial phase, ω -3 PUFA carried in CR modulate molecular events in endothelial cells (ECs) and monocytes to reduce arterial wall dysfunction and thus retard atherosclerosis development. The specific questions to be addressed are do ω -3 PUFA carried in CMR: 1. inhibit pro-inflammatory and pro-oxidant signalling pathways, altering the balance of inflammatory mediator release, and/or inducing protective signalling pathways? 2. inhibit reactive oxygen species (ROS) production and pro-inflammatory signalling) and by limiting their adherence to ECs? 3. Alter the global molecular phenotypes of human ECs and monocytes to favour vascular protection? Industrial Characterisation of the pathways and functions targeted by ω -3 PUFA carried in Impact CRs will lead to a better understanding of the fundamental biological pathways responsible for CR-mediated actions on the vascular wall, and may also reveal novel beneficial actions of these fatty acids. Knowledge of these cellular events is absolutely critical for refining the use of existing food supplements as well as for informing the development of new supplements, and thus will impact directly on the ability of the food industry to produce and market foods with substantiated health benefits. 24
