editor's welcome

editor's welcome food and nutrition security (fns) has an evolving nature and during the last decades its theoretical, conceptual, structural, practical and programmatic notions evolved significantly and approaches toward food and nutrition have changed drastically. now, more than ever before, the issue is considered as a fundamental component of sustainable development globally. for a better grasp of the complexities of the field, we need to remind ourselves that “nutrition” as science has a history of more than 100 years while nutrition as a “factor” in “national development” has a history of around fifty years. considering distinct levels of development status in different contexts, fns pattern is non-monotonic even in one country. accordingly, struggling against food and nutrition insecurity is very thought to deal with and multi disciplinary and multi sectoral approaches should be applied. providing robust evidences to feed policy making processes is one of the main prerequisites for evidence informed policy making and repositioning nutrition as central to sustainable development. this is a professional duty of scholars in different sectors engaging with human development. the journal of nutrition and food security (jnfs) as a new journal in the field of food and nutrition security is trying to provide an excellent opportunity for researchers and scholars to publish their original works on approaches, challenges and solutions of food and nutrition hoping to provide data for decision makers to better design interventional programs aiming to eradicate food and nutrition insecurity. editor-in-chief hassan mozaffari-khosravi
