Special Issue Information

Dear Colleagues,

This special issue highlights bioactive compounds derived from commonly consumed plants that offer well-documented health benefits. Unlike general plant nutrition studies, we focus on the specific physiological advantages of functional bioactives—such as polyphenols, flavonoids, carotenoids, glucosinolates, terpenes, and alkaloids—and their mechanisms in disease prevention and health promotion.

These plant-derived compounds deliver targeted benefits, including potent antioxidant and anti-inflammatory effects, immune modulation, cellular protection, gut microbiota regulation, and metabolic support. Their applications in cardiovascular health, neuroprotection, glycemic and lipid control, anti-aging, and cancer risk reduction are of particular interest.

As preventive health strategies gain global attention, scientifically validated plant bioactives offer natural solutions for reducing chronic disease risks and enhancing well-being. This issue welcomes research on the bioavailability and mechanisms impacts of these compounds, as well as their integration into functional foods and dietary interventions.

By bridging phytochemistry, nutritional science, and functional food development, this collection provides evidence-based insights for promoting healthspan, guiding dietary recommendations, and advancing plant-based  food industry.

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 250 words) can be sent to the Editorial Office for assessment.

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. Foods 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.

This study systematically examines the effects of processing methods (green vs. black tea) and preparation techniques (brewing vs. decoction) on the flavor and functional composition of Chinese sweet tea (Lithocarpus litseifolius). Fermentation degree and extraction temperature were found to significantly influence polyphenol bioavailability, with green tea exhibiting the highest polyphenol and flavonoid contents (144.51 mg/g and 88.97 mg/g, respectively), while black tea showed an approximately 40% reduction in catechin levels due to oxidative polymerization. During in vitro simulated digestion, green tea maintained strong antioxidant activity despite its stronger bitter–astringent taste. Notably, in vitro fecal fermentation experiments demonstrated that sweet tea significantly promoted short-chain fatty acid (SCFA) production and modulated gut microbiota composition (with a 3.2-fold increase in acetate content in the black-tea decoction group). Black tea particularly enhanced beneficial genera (Roseburia and Coprococcus) after 24 h fermentation (p < 0.05) and exhibited superior prebiotic properties. Principal coordinate analysis confirmed there were significant structural differences in microbial communities among the treatment groups. This study is the first to reveal that processing methods regulate the prebiotic efficacy of sweet tea by modulating the bioaccessibility of active compounds, providing a theoretical foundation for the development of functional sweet tea products.
