Special Issue Information

Dear Colleagues,

Dairy foods such as milk, cheese, and yogurt are essential foods in a healthy diet. Consuming dairy as part of a larger healthy diet helps people thrive at every age. Dairy foods can contribute to our intake of important shortfall nutrients, including calcium, vitamin D, and potassium, as well as several other essential nutrients, such as protein, vitamin A, vitamin B12, riboflavin, phosphorus, zinc, iodine, and selenium.

Globally, the increasing incidence of metabolic diseases requires more actionable diet and food recommendations to help reduce risk.  Research indicates that eating dairy is associated with a reduced risk of type 2 diabetes, cardiovascular disease, obesity, metabolic syndrome, and hypertension. Despite the sometimes negative perception of whole-milk dairy foods due to their saturated fat content, growing evidence indicates that they can be included in healthy dietary patterns. This evidence supports the concept of looking at dairy foods as a whole—the dairy matrix—as they can impact digestion, absorption, bioavailability, and overall human health, due to the relationships between their nutrient and non-nutrient components (e.g., vitamins and minerals), and due to their physical structure, texture, and form (e.g., solid, gel, liquid).

Emerging evidence, mostly from in vitro and animal studies, has suggested that the multiple health benefits attributed to the consumption of dairy foods may be related to the presence of bioactive components embedded in the major milk proteins, carbohydrates, and fats, which have potential health-promoting activities.

For this Special Issue of Nutrients, our aim is to further advance this line of research, by both expanding our knowledge and exploring new insights into the role dairy foods and/or dairy components might play in human health. We invite the submission of original research, including dietary intervention trials, observational studies, systematic reviews, meta-analyses, animal and mechanistic studies, etc., and review papers on the subject as well.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Abstract
Full-fat dairy milk may protect against cardiometabolic disorders, due to the milk fat globule membrane (MFGM), through anti-inflammatory and gut-health-promoting activities.

Full-fat dairy milk may protect against cardiometabolic disorders, due to the milk fat globule membrane (MFGM), through anti-inflammatory and gut-health-promoting activities. We hypothesized that a MFGM-enriched milk beverage (MEB) would alleviate metabolic endotoxemia in metabolic syndrome (MetS) persons by improving gut barrier function and glucose tolerance. In a randomized crossover trial, MetS persons consumed for two-week period a controlled diet with MEB (2.3 g/d milk phospholipids) or a comparator beverage (COMP) formulated with soy phospholipid and palm/coconut oil. They then provided fasting blood and completed a high-fat/high-carbohydrate test meal challenge for evaluating postprandial metabolism and intestinal permeability. Participants had no adverse effects and achieved high compliance, and there were no between-trial differences in dietary intakes. Compared with COMP, fasting endotoxin, glucose, incretins, and triglyceride were unaffected by MEB. The meal challenge increased postprandial endotoxin, triglyceride, and incretins, but were unaffected by MEB. Insulin sensitivity; fecal calprotectin, myeloperoxidase, and short-chain fatty acids; and small intestinal and colonic permeability were also unaffected by MEB. This short-term study demonstrates that controlled administration of MEB in MetS persons does not affect gut barrier function, glucose tolerance, and other cardiometabolic health biomarkers, which contradicts observational evidence that full-fat milk heightens cardiometabolic risk.

Nutrition research has shifted from single nutrients to examining the association of foods and dietary patterns with health. This includes recognizing that food is more than the sum of the individual nutrients and relates to the concept of the food matrix. Like other foods, dairy foods are characterized by their unique matrices and associated health effects. Although the concepts of the food matrix and/or dairy matrix are receiving increasing attention in the nutrition and health literature, there are different terms and definitions that refer to it. This article aims to provide insights into the application of the concepts of the food matrix and dairy matrix and to provide a current overview of the definitions and terminology surrounding the food matrix and dairy matrix. By analysing these aspects, we aim to illustrate the practical implications of the food matrix and dairy matrix on nutrition and health outcomes and evaluate their roles in shaping evidence-based policies for the benefit of public health. There is a need for harmonized definitions within the literature. Therefore, the International Dairy Federation put forward harmonized terms to be internationally applicable: the “dairy matrix” describes the unique structure of a dairy food, its components (e.g., nutrients and non-nutrients), and how they interact; “dairy matrix health effects” refers to the impact of a dairy food on health that extend beyond its individual components.
