Special Issue Information

Dear Colleagues,

In recent years, it has become increasingly evident that many chronic diseases are linked to dysbiosis of the intestinal microbiota. These disturbances encompass a wide range of conditions, ranging from metabolic disorders (e.g., diabetes, obesity), through autoimmune diseases (e.g., Crohn’s disease, ulcerative colitis), to mental health issues (e.g., depression, autism). The noticeable rise in the prevalence of these conditions is attributed, at least in part, to poor dietary habits and the consumption of low-quality food, while the role of the gut microbiota is receiving growing scientific attention.

The concept of enhancing gut function through proper nutrition and the use of beneficial microbes dates back to the late 19th century. However, only now do we have the scientific tools and understanding to purposefully apply probiotic, prebiotic, and synbiotic products, which not only support the digestive system but also contribute to managing the aforementioned disorders. This expanding knowledge also empowers us to make more informed dietary choices, particularly through incorporating functional foods, i.e., foods enriched with health-promoting components such as probiotic microbial strains, vitamins, polyphenols, high-quality dietary fiber, and other bioactive compounds. Underlying these ideas is the farm-to-fork concept, which promotes sustainable and health-oriented food systems, spanning the entire chain from agricultural production to final consumption.

All of these elements are interconnected within the One Health framework, developed two decades ago and defined as “an integrated and unifying approach to sustainably balance and optimize the health of people, animals, and ecosystems.” This concept highlights the deep interdependence between human health, the well-being of cultivated plants and livestock, and the broader environmental context.

This Special Issue explores the role of multi-omics approaches in advancing the One Health framework, focusing on probiotics, functional foods, and the farm-to-fork concept. By integrating genomics, metabolomics, microbiomics, and other omics technologies, it will highlight innovative strategies for improving human, animal, and environmental health through nutrition, sustainable food systems, and microbiome modulation.

The rising use of medicinal plant food supplements in Europe reflects a growing consumer shift toward natural health solutions and sustainability-driven lifestyles. The study aims to synthesize current literature and regulatory frameworks to better understand the drivers behind medicinal plant food supplements use and the challenges within the botanical products market. Findings reveal that usage patterns are strongly influenced by age, gender, income, education level, and cultural traditions, with women, older adults, and health-conscious individuals leading consumption. Consumers increasingly demand products that are organic, traceable, and ethically sourced, aligning with broader sustainability goals. However, discrepancies in national regulations, transparency in labeling, and environmental concerns such as over-harvesting persist across the European Union (EU). The distinction between Food Supplements (FSs) and Traditional Herbal Medicinal Products (THMPs) under current EU directives contributes to market fragmentation and consumer confusion. In conclusion, harmonizing regulatory standards, promoting responsible sourcing, and integrating traditional knowledge into sustainable production models are essential for ensuring safety, consumer trust, and long-term ecological viability in the medicinal plant food supplement sector.

The investigation of the human intestinal microbiota has rapidly become one of the most dynamic and interdisciplinary fields in modern biomedical science, and for good reasons. Since the 1990s, when the microbiota was first described as the “neglected organ”, research has expanded exponentially, uncovering its fundamental roles in maintaining immune homeostasis, regulating host metabolism, which gave rise to the term “second liver”, and influencing neural activity through the dense network of enteric neurons, which justifies its characterization as the “second brain”. Furthermore, the remarkable genetic richness of the microbiota, comprising a gene pool vastly exceeding that of the human genome, has earned it the title of the “second genome”. Tracing the origins of this scientific field reveals that the concept of the gut as a complex microbial ecosystem emerged gradually, shaped by pivotal developments in microbiology and medicine throughout the 19th and early 20th centuries. The rise of the germ theory, the advancement of microscopy, and the discovery of key microbial phenomena, including fermentation, decomposition, bacteriophages, probiotics, and antibiotics, collectively transformed our understanding of microorganisms from pathogens to essential symbionts. This review aims to provide a historical perspective on how these landmark discoveries laid the conceptual and methodological foundations for contemporary microbiota research. By highlighting the scientific milestones that shifted perceptions of microbes from “bad germs” to “good germs”, it seeks to offer readers, whether from biomedical, ecological, or philosophical backgrounds, an integrative view of how this paradigm evolved and why it remains central to current human health discussions.
