“The aim of Frontiers in Nutrition is to integrate major scientific disciplines in this vast field in order to address the most relevant and pertinent questions and developments.” At the dusk of the Millennium Development Goals (MDGs) and the dawn of the Sustainable Development Goals (SDGs) we wanted to give leading thinkers in nutrition science the opportunity to share with our readers where they think the Frontiers are located. You will find the products of their thought in this edition of the magazine, in whose pages you can explore a wide variety of topics including multiple micronutrients in pregnancy, epigenetics, biomarkers and bio-indicators, benefit-risk assessment, inflammation, nutrigenetics and nutrigenomics, proteomics and metabolomics, mobile health, systems nutrition, and food systems, as well as early life nutrition and the developmental origins of adult disease.
