Special Issue Information

Dear Colleagues,

Society's growing concern for health has led to a worldwide increase in interest in proper nutrition. In recent years, much research has been directed towards studying the biochemistry of foods and how these compounds interact with the human body to influence disease prevention, delay ageing and maintain good mental health.

Recent research has focused on the development of functional foods rich in specific nutrients that provide additional health benefits beyond basic nutrition, as well as the search for new foods and the development of food supplements that facilitate personalised nutrition, taking into account the genetic and metabolic characteristics of each individual with specific diets.

The biochemistry of food and health is a dynamic and evolving field. Processes, with its Special Issue “Food Biochemistry and Health: Recent Developments and Perspectives”, aims to provide a forum to highlight the latest advances in the knowledge of food composition and its application to the development of healthy diets.

The aim of this study was to investigate the im pact of incorporating flaxseed cake into wheat muffins on the levels of selected nutritional and bioactive compounds, specifically total polyphenols, phenolic acids, flavonols, and flavonoids. The influence of different levels of this additive on the quality attributes of the final product—such as color, texture, and volume—was also assessed. Furthermore, the health-promoting potential of the enriched muffins was analyzed using two free radical scavenging methods (DPPH and ABTS). The findings demonstrated that incorporating flax cake significantly increased the content of polyphenols and flavonoids (up to threefold) and phenolic acids (up to fortyfold). This highlights the potential of using flax cake to enrich food products and enhance the bioactive compound content of wheat muffins. Higher levels of flax cake addition (20%, 30%, and 40%) resulted in a notable increase in antioxidant activity, thereby enhancing the health-promoting properties of the muffins. Muffins with a 10% addition of flax cake exhibited comparable volume and reduced hardness relative to the control and a pleasant color. Full article

Background: We evaluated certain factors relative to onion (Allium spp.) and onion-derived polyphenols. Methods: We searched PubMed, Scopus, and Google Scholar from 2010 to 20 October 2025 without language limits. Eligible designs comprised of in vitro, animal, and human studies assessing onion, onion extracts, or isolated onion-derived polyphenols with bone outcomes. Two reviewers independently screened, extracted, and assessed risk of bias (RoB 2 for RCTs; SYRCLE for animals). Results: We included X studies (a in vitro, b animal, and c human RCTs; N samples). In vitro limitations included the following: heterogeneous models, short human follow-up, small samples, and moderate-to-serious risk of bias in animals. Reports included improvements in bone mineral density (BMD), bone mineral content (BMC), bone turnover markers, and osteoclast/osteoblast activity. Onion extracts consistently inhibited RANKL-induced osteoclastogenesis while sparing osteoblast function. In animals, onion or quercetin/kaempferol preserved BMD and improved mineral content and (in several models) fracture healing. In one small RCT of onion juice (8 weeks), antioxidant status improved with a trend to attenuated BMD loss; a resveratrol RCT was excluded/included as a benchmark. Conclusions: Pre-clinical evidence suggests anti-resorptive and osteogenic effects of onion-derived polyphenols; human evidence is limited and characterized by low certainty. Longer RCTs are needed to define effective doses and clinical relevance. Full article

Glutamate is one of the major naturally occurring non-essential amino acids. The aim of this review is to provide a comprehensive analysis of the role of glutamate as a key metabolite in the metabolism of plant and animal organisms. Its role in nutrition and neurotransmission has intrigued researchers for many years. In both plants and animals, glutamate primarily exists in a monoanionic form characterised by unique physical and chemical properties. In plants, it is involved in the glutamine synthetase/glutamate synthase (GS/GOGAT) cycle, while in animals, it plays a role in the glutamine/glutamate cycle, which is closely related to the urea cycle. Glutamate is also closely linked to the Krebs cycle in both groups of organisms through α-ketoglutarate. Glutamate is essential in both biosynthetic and catabolic pathways and participates in numerous physiological processes in plants and animals. Animals acquire glutamate from food, while plants acquire it from the soil; however, both also synthesise it de novo. Once present in the body, it is transported across cell membranes by specific transporters driven by ionic gradients (a mechanism known as secondary active transport). It is involved in cellular and systemic signalling pathways by interacting with ionotropic and metabotropic receptors. Additionally, glutamate is an important ‘building block’ of many proteins, including storage proteins. It also occurs in the form of monosodium glutamate (MSG), a flavour enhancer that is widely used but often criticised. Due to its important role in metabolism and signalling, the significance of glutamate in nutrition and its impact on human health are vital areas of research in food biochemistry. These investigations contribute to the development of nutritious food products and the design of effective pharmaceuticals. In this paper, we also address unresolved questions in glutamate research and consider its practical applications. Full article

Nitrosamines (NAs) are a class of chemical compounds predominantly formed during the processing, curing, and storage of meat products through the reaction of nitrites with amines. Decades of toxicological and epidemiological evidence have unequivocally established several NAs as potent human carcinogens, with strong associations with gastrointestinal, pancreatic, and liver cancers. This review critically examines the pathways of NA formation in meat, the influence of processing conditions, and the factors contributing to their variability in food products. It also outlines state-of-the-art analytical techniques for their detection and summarizes recent scientific efforts to reduce their formation. Despite scientific consensus on the health hazards posed by dietary exposure to NAs, regulatory control remains fragmented and insufficient. Therefore, this review highlights the pressing need for coordinated international action and the development of a harmonized regulatory framework to mitigate public health risks. Full article
