Life expectancy is increasing across the globe but this success comes at a cost. Poor health in later life is putting an increasing strain on health and social care budgets and there is a need to ensure that physical and mental health is maintained as long as possible into old age. Some individuals are genetically predisposed to health and longevity but there is a growing awareness of the way in which diet across the whole of life can influence health and longevity. Health and life expectancy are also strongly related to socioeconomic status but the causal links with diet and behaviour are poorly understood.
The aim of this research is to investigate the way in which diet influences human health and healthy ageing at different stages in life and how this is modulated by genetics and socioeconomic status.
