The concept of personalised nutrition emerged following the sequencing of the human genome in 2000. It was hoped that with the identification of gene nutrient interactions, an individual's response and susceptibility to particular diets would be better understood and therefore appropriate dietary modifications could be made to optimise health and lower disease risk. Then Food4Me aims to study the development of personalized nutrition at three levels and determine whether providing more personalised dietary advice leads to better compliance and health outcomes compared to standard population advice.
