Dear Colleagues,

Glycaemic load (GL) defines the overall glycaemic impact of carbohydrate consumption and can be modified by lowering either the glycaemic index (GI) or the available carbohydrate content. Elevated postprandial glycaemia has been reported to be a significant driver of chronic disease. Diets with a lower glycaemic response are associated with a wide range of health benefits and are specifically linked to a decreased risk of type 2 diabetes and cardiovascular events. Yet, further research on the topic of glycaemic load and human health is needed to fill research gaps, such as (1) the relevance in populations other than adults, such as children and adolescents; (2) GI data of regional foods; (3) novel methods to measure glycaemic responses in different settings/populations; (4) the estimation of dietary GL, particularly in epidemiological studies; (5) the relevance of different postprandial windows (1h vs 2h vs 3h); (5) aspects considering the diurnal rhythm of glucose homeostasis; (6) how to improve compliance with a low-GL diet; (7) and the sustainability of low-GL diets.

This Special Issue of Nutrients therefore encourages the submission of original research or systematic reviews (including meta-analyses) addressing the above-mentioned research gaps.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
