Special Issue Information

Dear Colleagues,

Diabetes is becoming a major public health concern as its global incidence rises. Chronic complications and the associated high risk of morbidity and mortality represent serious consequences of diabetes which have serious effects on healthcare systems as well. Diet represents a vital aspect of managing diabetes since it helps control blood sugar levels, reduce complications, and enhance overall health. Given the importance of nutrition in preventing and managing diabetes and its consequences, we require a greater and more accurate knowledge of the mechanisms that make healthy diets effective. A better comprehension of the interplay between dietary components and gut microbiota, the pathways modulating dietary nutrient intake and the effects of also using omics approaches, and digital technologies/tools to increase adherence to healthy diets is required to have a holistic view of how to manage diabetes through diet.

The aim of this Special Issue on "Current and new approaches to managing Diabetes through Diet" is to highlight different aspects of diabetic nutrition and the importance of dietary management of blood sugar levels and the prevention of diabetes complications.

This Special Issue welcomes contributions of articles related to this topic; recommended reviews and original articles, brief reports, and communications are also welcome.

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.

Type 2 diabetes mellitus (T2DM) is a major public health concern associated with high mortality and reduced life expectancy. Since diabetes is closely linked with lifestyle, not surprisingly, nutritional intervention and increased physical activity could play a vital role in attenuating the problems related to diabetes. Protein hydrolysates (PHs) and their bioactive peptides (BP) have been shown to exert a wide range of biological effects, including antioxidative, antihypertensive, and in particular, hypoglycaemic activities. To better understand the efficacy of such interventions, a systematic review and meta-analysis of randomised controlled trials (RCTs) were performed concerning the influence of protein hydrolysates on glycaemic biomarkers in subjects with and without hyperglycaemia. Five different databases were used to search for RCTs. In total, 37 RCTs were included in the systematic review and 29 RCTs in the meta-analysis. The meta-analysis revealed a significant reduction in postprandial blood glucose response (PPGR) in normoglycaemic (−0.22 mmol/L; 95% CI −0.43, −0.01; p ≤ 0.05) and in hyperglycaemic adults (−0.88 mmol/L; 95% CI −1.37, −0.39; p ≤ 0.001) compared with the respective control groups. A meta-regression analysis revealed a dose-dependent response for PPGR following PH consumption in normoglycaemic adults, specifically for doses ≤ 30 g. The postprandial blood insulin responses (PPIR) were significantly higher after the ingestion of PHs in both the group with and the group without hyperglycaemia, respectively (23.05 mIU/L; 95% CI 7.53, 38.57; p ≤ 0.01 and 12.57 mIU/L; 95% CI 2.72, 22.41; p ≤ 0.01), compared with controls. In terms of long-term responses, there was a small but significant reduction in both fasting blood glucose (FBG) and fasting glycated haemoglobin (HbA1c) in response to PH compared with the control group (p < 0.05). The PHs significantly improved the parameters of glycaemia in adults and, hence, it may contribute to the management and regulation of the future risk of developing T2DM. Full article
