Reported foodservice environmental sustainability practices in Australian healthcare and aged care services pre and post the onset of COVID-19.

Aims: Healthcare foodservices substantially impact global environmental changes. This study investigated environmentally sustainable practices in Australian health foodservices; and perceptions of the influence of COVID-19 on foodservice environmental sustainability.

Methods: An observational study was undertaken collecting data at two time points (2019 and 2022) via a pre-workshop survey with healthcare foodservice stakeholders.

Feasibility Trial Exploring Immune-Related Biomarkers Pertaining to Rapid Immune Surveillance and Cytokine Changes after Consuming a Nutraceutical Supplement Containing Colostrum- and Egg-Based Low-Molecular-Weight Peptides.

Immune protection associated with consuming colostrum-based peptides is effective against bacterial and viral insults. The goal for this study was to document acute changes to immune surveillance and cytokine levels after consuming a single dose of a nutraceutical blend in the absence of an immune challenge. A double-blind, randomized, placebo-controlled, cross-over pilot study involved healthy participants attending two clinic visits.

Effects of a β-Glucan-Rich Blend of Medicinal Mushrooms and Botanicals on Innate Immune Cell Activation and Function Are Enhanced by a Very Low Dose of Bovine Colostrum Peptides.

Nutraceutical immune support offers potential for designing blends with complementary mechanisms of action for robust support of innate immune alertness. We documented enhanced immune activation when bovine colostrum peptides (BC-Pep) were added to an immune blend (IB) containing β-glucans from yeast, shiitake, maitake, and botanical non-β-glucan polysaccharides. Human peripheral blood mononuclear cells (PBMCs) were cultured with IB, BC-Pep, and IB + BC-Pep for 20 h, whereafter expression of the activation marker CD69 was evaluated on NK cells, NKT cells, and T cells.

Secreted Metabolites from , , and Biofilm: Modulation of Immunogenicity by a Nutraceutical Enzyme and Botanical Blend.

Bacterial biofilms are hardy, adaptable colonies, evading immune recognition while triggering and sustaining inflammation. The goals for this study were to present a method for testing the immunogenicity of secreted metabolites from pathogenic biofilm and to document whether biofilm treated with a nutraceutical enzyme and botanical blend (NEBB) showed evidence of reprogrammed bacterial metabolism, potentially becoming more recognizable to the immune system. We screened immune-modulating properties of metabolites from established biofilm from (Pa), (Ss), and (Bb).

Differential Immune-Modulating Activities of Cell Walls and Secreted Metabolites from Probiotic JBI-YZ6.3 under Normal versus Inflamed Culture Conditions.

Spore-forming probiotic bacteria, including , are resilient and produce a variety of beneficial metabolites. We evaluated the immune-modulating effects of the novel probiotic strain JBI-YZ6.3, where the germinated spores, metabolite fraction, and cell wall fraction were tested in parallel using human peripheral blood mononuclear cell cultures under both normal and lipopolysaccharide-induced inflamed culture conditions.
