The Journal of Human Nutrition and Dietetics operates to a strict annual page budget and prioritises the publication of original articles and reviews. We rarely publish letters to the editor that are comments or responses to published papers. However, the need for discussion and debate about work is something that we recognise and value. As a journal with an active blog, we welcome letters to the editor for publication on this site. Any letters or comments on specific articles will be passed on to the authors of the original paper with an invitation to make a response, again through this site.
