Exploring the Immune-Boosting Functions of Vitamins and Minerals as Nutritional Food Bioactive Compounds: A Comprehensive Review

Food components have long been recognized to play a fundamental role in the growth and development of the human body, conferring protective functionalities against foreign matter that can be severe public health problems. Micronutrients such as vitamins and minerals are essential to the human body, and individuals must meet their daily requirements through dietary sources. Micronutrients act as immunomodulators and protect the host immune response, thus preventing immune evasion by pathogenic organisms. Several experimental investigations have been undertaken to appraise the immunomodulatory functions of vitamins and minerals. Based on these experimental findings, this review describes the immune-boosting functionalities of micronutrients and the mechanisms of action through which these functions are mediated. Deficiencies of vitamins and minerals in plasma concentrations can lead to a reduction in the performance of the immune system functioning, representing a key contributor to unfavorable immunological states. This review provides a descriptive overview of the characteristics of the immune system and the utilization of micronutrients (vitamins and minerals) in preventative strategies designed to reduce morbidity and mortality among patients suffering from immune invasions or autoimmune disorders.

Identification of G protein-coupled receptor 55 (GPR55) as a target of curcumin

The identification of molecular targets of bioactive food components is important to understand the mechanistic aspect of their physiological functions. Here, we have developed a screening system that enables us to determine the activation of G protein-coupled receptors (GPCRs) by food components and have identified GPR55 as a target for curcumin. Curcumin activated GPR55 and induced serum-response element- and serum-response factor-mediated transcription, which were inhibited by Rho kinase and GPR55 antagonists. Both the methoxy group and the heptadienone moiety of curcumin were required for GPR55 activation. The F1905.47 residue of GPR55 was important for the interaction with curcumin. The curcumin-induced secretion of glucagon-like peptide-1 in GLUTag cells was inhibited by a GPR55 antagonist. These results indicate that expression screening is a useful system to identify GPCRs as targets of food components and strongly suggest that curcumin activates GPR55 as an agonist, which is involved in the physiological function of curcumin.

Nutrigenomics: future for sustenance

Nutrigenomics deals with the effect of foods and food constituents on gene expression. It is a new concept in disease prevention and cure. Nutrigenomics conveys how nutrients influence our body to express genes, whereas nutrigenetics refers to how our body responds to nutrients. The various bioactive food components can alter the gene expression mechanisms. But our actual knowledge is so insufficient that the only use of such information may help to satisfy our imagination. If science could arrive at some more precise facts, that would have vast applications in medicine.

Prevention effects of black soybean polyphenols on non-alcoholic fatty liver disease in three different model mice

Non-alcoholic fatty liver disease (NAFLD) and its advanced stage, non-alcoholic steatohepatitis (NASH) are a major health issue throughout the world. Certain food components such as polyphenols are expected to possess...

Product Preservation Design of Vegetable and Animal Food Processing

The aims of the research is determine the Product Preservation Design of Vegetable and Animal Food Processing. Packaging designed to preserve food components in the hands of customers while preventing contamination by bacteria and fungus is the goal. As long as food is stored properly, the quality of the food will deteriorate. Packaging is necessary in order to deliver the following information: Package must convey an accurate representation of its contents; it should neither be copied from other parties' packaging designs, nor should it be too complex, making it prohibitively costly to produce

Polysaccharide hydrolyzing enzyme activity of bacteria, native to Apis florea gut

Introduction and Aim: Apis florea commonly known as “dwarf honey bee” harbors enormous gut bacteria that can digest complex carbohydrates and other food components. In this regard, the present investigation was focused on analyzing the polysaccharide degrading ability of bacteria isolated from the gut of honeybee, for their possible application in nutraceutical and pharmaceutical industries. Materials and Methods: Nine bacterial isolates were screened for carbohydrate degrading enzymes viz., amylase, pectinase, cellulase, tannase and laccase, using respective substrate by plate assay method. Further activities of amylase and pectinase were measured quantitatively by dinitrosalicylic acid (DNS) method. Results: All the nine selected isolates exhibited amylase and pectinase activities. However, only two isolates exhibited lignolytic and cellulolytic activity. None of the isolates showed tannin degradation. Maximum amylase activity (4.95 U/mg) was observed in Bacillus halotolerans af-M9 followed by Klebsiella oxytoca af-G4 (4.62 U/mg). With respect to pectinase activity Klebsiella pneumoniae af-E17 displayed higher activity (0.24 U/mg) followed by Klebsiella oxytoca af-G4 (0.20 U/mg). Conclusion: Habitat-specific innovations are being explored for novel compounds for therapeutic applications. This study throws a light on selection of carbohydrate degrading bacteria from a new source i.e., GUT of honeybee.
