Since each individual person differs from the next in multiple ways, it is a beguiling idea that the nutritional needs of each person are also different. During this 60 minute webinar, Professor John Mathers, Newcastle University, will analyse the findings from well-conducted nutritional intervention studies that provide evidence demonstrating that there is considerable inter-individual variation in response to exactly the same dietary exposure. Professor Mathers will discuss the limited understanding of the physiological mechanisms responsible for this variation, but also the excitement around the role of genes in explaining inter-individual differences, following sequencing of the human genome.

Eating patterns have a major influence on health. As a result, much public health advice intended to reduce the risk of common complex diseases aims to improve diet. However, most dietary interventions are relatively ineffective, and personalised approaches which tailor the intervention to the individual may be both more acceptable and more effective (Celis-Morales et al.2015; Ordovas et al. 2018). Professor Mathers will use evidence from the Food4Me Study (Celis-Morales et al. 2017) to discuss the utility of personalised approaches in helping individuals to make healthier dietary choices.
