Human nutrition research is key to understanding and improving health in society. Our research creates, advances and disseminates nutrition research to make an impact on population health. Our research has a life course focus, with studies on diet in pregnancy, childhood, adolescents and the elderly. One emphasis is exploration of the relationship of diet to chronic disease development. The excellence of our work around sugars and health, has been recognised through the Nutrition Society’s award of the 2016 Public Health Nutrition Medal to Dr Charlotte Evans.Much of our work draws on the UK Women’s Cohort Study, one of the largest and longest running studies of this type in the UK http:/ukwcs.leeds.ac.uk/. Our public health and policy facing work has led to changes in Government advice around consumption of caffeine in pregnancy and supported national guidance on sugar intake. On the international stage, we are developing a WHO Collaborating Centre in Nutritional Epidemiology, the first of its kind in the world. Our contribution includes work on National Diet and Nutrition Surveys in Europe and portion size determination.
