Research interests

In her N8 role, Louise is interested in how to encourage and sustain dietary behaviour change at individual, organisational and societal levels, linking to global issues of food production/supply, inequality and health. Her particular expertise is the effects of food and food components on cognitive performance, digestive function and appetite control including in altered metabolic states such as obesity and type 2diabetes, dementia as well as genetic disorders such as PKU and Cystic Fibrosis. Louise has published a number of influential systematic reviews and meta-analyses on the effects of breakfast on academic, cognitive and behavioural outcomes in children and adolescents, iron deficiency/supplementation and cognition in children and young women, and studies on the effects of different food components (e.g. polyphenols) to maintain mental performance and prevent cognitive decline. She currently sits on the BBSRC Biosciences for Health Strategic Advisory Panel, the International Life Sciences Institute (ILSI). scientific advisory board and five of its expert groups, including natural ingredients for mental performance. She is Chair of the Scientific Advisory Board of the FP7 project “PREVIEW” which is aimed at the prevention of type 2 diabetes. She is collaborating on a WUN project on diet and dementia in the townships of the Eastern and Western Cape, South Africa.

  Professor Louise Dye's research in The Human Appetite Research Unit (HARU) directly addresses major issues of concern to society, the impact of food on health in terms of cognitive function and wellbeing and also appetite/satiety, body weight control and obesity. Louise’s research focuses on key concerns of the food industry and government, specifically the evaluation of food and food components and their effects on appetite control, cognitive function and well-being. There are few research groups in the world who are able to examine the effects of food on appetite control concurrently with glycaemic response and cognitive function. This places her research partnership with Dr Clare Lawton in a unique position with clear knowledge transfer opportunities. With colleagues in the NHS, Louise is examining cognition and diet in relation to phenylketonuria, cystic fibrosis, diabetes, chronic fatigue syndrome, obesity, PCOS and infertility. 

With colleagues in FBS, Louise is researching the effect of nutrition on behaviour, well-being and cognition in pigs. She collaborates across the N8 Agrifood programme with projects related to food insecurity, psychological stress and obesity/malnutrition in children and the elderly and on global challenges research in Argentina and across the world (e.g. Breakfast study with Dr Patricio Kenny, Pontificia Universidad Católica, Buenas Aires) .
