Oyster, as a common aquatic food, play an important role in shellfish allergy. In this study, 2 tropomyosin (TM) isoforms TM-α and TM-β (TM-α/-β) in Alectryonella plicatula were identified. The sequences of 852 bp encoding 284 amino acids of TM-α/-β and 2 recombinant proteins were obtained, respectively. There were 12 amino acid differences between TM-α/-β. The results of immunological experiments indicated that TM-β had stronger immunobinding activity and immunoreactivity than those of TM-α. Structural analysis showed that TM-β had more α-helix and higher surface hydrophobicity than TM-α. Sequences and epitopes alignment with shellfish TMs revealed that amino acids of TM-β were more frequently recognized as IgE epitopes in other shellfish TMs than TM-α. Differences in structure and sequence account for the higher immunological activity of TM-β compared to TM-α. These findings provide a theoretical basis for enriching the understanding of shellfish TM and accurate diagnosis of allergic components.

Beer is a fermented beverage prepared from water, malted barley, hops, and yeast that has been around for centuries. Alcoholic beverages alter the composition of the gut microbiota, which in turn causes oxidative stress brought on by alcohol, increases intestinal permeability to luminal bacterial products. However, beer has been shown to contain several intriguing non-alcoholic chemicals. Recent research demonstrates that moderate beer drinking could have positive impacts on human health. Beer's non-alcoholic ingredients have a significant impact on gut microbiota, and this type of diet is known to modulate gut microbiota, which has a variety of effects on the body, including effects on intestinal permeability, mucosal immune function, intestinal motility, antioxidant activity, and anti-inflammatory activity. Although the negative consequences of excessive alcohol intake are widely known, it is still debatable whether or not some non-alcoholic components, such as polyphenols and carbohydrates, have any positive benefits. In this review, we explain the primary benefits of moderate beer consumption on the gut microbiota, which are mostly attributable to non-alcoholic components such polyphenols. Despite any potential advantages of moderating consumption of alcoholic beverages, the lowest alcohol intake is the most secure.

Bone loss caused by ageing has become one of the leading health risk factors worldwide. Wheat germ (WG) is consists of high amounts of bioactive peptides, polyunsaturated fatty acids, and dietary fibre. Currently, WG has been proven to possess strong antioxidant and anti-inflammatory properties. We recently explored the beneficial effects and relevant mechanisms of a WG-rich diet (2.5 % and 5 % WG, m/m) on bone homeostasis in aged rats. Our results showed that 5 % WG supplementation for 12 months effectively attenuated ageing-induced microstructural damage and differentiation activity changes in the femur. The 5 % WG supplementation also significantly increased the levels of total antioxidant capacity (T-AOC), glutathione peroxidase (GSH-Px) (P < 0.01), and superoxide dismutase (SOD) (P < 0.05), and decreased inflammatory cytokine levels (tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)) (P < 0.01). Furthermore, the WG-rich diet reshaped the composition of the gut microbiota, enhancing short-chain fatty acids (SCFAs)-producing microbes and reducing inflammation-related microbes. In addition, metabolomics analysis showed that 5 % WG supplementation improved plasma metabolites related to bone metabolism. Conclusively, our study purports long-term WG-rich diet may preserve bone homeostasis by regulating gut microbiota and plasma metabolites in aged rats.

Gut microbiota plays an important role in food allergy. The immunoglobulin G (IgG)/immunoglobulin E (IgE) binding capacity and human gut microbiota changes of digestion products derived from glycated ovalbumin (OVA) were investigated. Gastrointestinal digestion effectively destroyed the primary structure of glycated OVA, resulting in a significantly higher digestibility than gastric digestion, and more abundant peptides < 3 kDa. Moreover, gastric and gastrointestinal digestion products have different fluorescence quenching and red shift of fluorescence peaks, and possess different conformational structures. These changes resulted in a decrease in 28.7 % of the IgE binding capacity of gastrointestinal digestion products beyond that of pepsin. Moreover, gastrointestinal digestion products of glycated OVA increased significantly the proportion of Subdoligranulum, Collinsella, and Bifidobacterium. Therefore, gastrointestinal digestion products of glycated OVA altered human intestinal microbiota, reducing the risk of potential allergy.

Infant formula (IF) based on cow milk and goat milk is a substitute food for infants who are underfed with human milk. In our previous study, we reported the composition and physicochemical stability of IF based on milk from cows and goats and a combination of both milks. Here, we investigated the effects of these 3 IFs on intestinal immunity and short-chain fatty acid production (SCFAs) using human microbiota-associated (HMA) mice and selected human milk as a positive control. The results showed that goat milk-based IF is associated with a functional immune advantage, due to the rise in the levels of immune-related cytokines interleukin (IL)-2 and IL-10, decreased levels of intestinal permeability markers D-lactic acid and endotoxin, and increased mRNA levels of intestinal tight junction proteins occludin and claudin. In addition, the intestine of mice fed with goat milk-based IF contained 12.06 μmol/g acetate, 2.42 μmol/g propionate, and 1.72 μmol/g butyrate, which reached 69 %, 79 %, and 60 % of the levels in human milk, respectively. Our results indicate that goat milk-based IF improves intestinal immune function and promotes the production of intestinal SCFAs.

Flaxseed lignan macromolecules (FLM) are a class of important secondary metabolites in flaxseed, which have been widely concerned due to their biological and pharmacological properties, especially for their antioxidative activity. For the composition and structure of FLM, our results confirmed that ferulic acid glycoside (FerAG) was directly ester-linked with herbacetin diglucoside (HDG) or pinoresinol diglucoside (PDG), which might determine the beginning of FLM biosynthesis. Additionally, p-coumaric acid glycoside (CouAG) might determine the end of chain extension during FLM synthesis in flaxseed. FLM exhibited higher antioxidative activity in polar systems, as shown by its superior 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging capacity compared to the 2,2'-azinobis(3-ehtylbenzothiazolin-6-sulfnic acid) (ABTS) cation free radical scavenging capacity in non-polar systems. Moreover, the antioxidative activity of FLM was found to be highly dependent on its composition and structure. In particular, it was positively correlated with the number of phenolic hydroxyl groups (longer FLM chains) and inversely related to the steric hindrance at the ends (lower levels of FerAG and CouAG). These findings verified the potential application of FLM in non-polar systems, particularly in functional food emulsions.

Selenopeptides may be a valuable bioactive compound to promote gut microbiota-targeted therapeutic methods for intestinal disease and hepatopathy. However, limited information is available on the utilization of selenopeptides by gut microbiota, especially Selenium (Se) function. For this purpose, the present study aimed to investigate the protective effect of selenopeptide (RYNA(Se)MNDYT, Se-P2, purity of ≥ 95 %) and its original peptide (RYNAMNDYT, P2, purity of ≥ 95 %) in vivo by the microbiota-metabolite axis and further analyze the potential contribution of Se biofortification to Se-P2 bioactivity. The results showed that Se-P2 exhibits a higher protective effect on lipopolysaccharide (LPS)-induced inflammation than P2, including pathology of the colon and liver, which suggested that the bioactivity of P2 was promoted by the organic combination of Se. Notably, gut microbiota composition tended to be a healthy structure by Se-P2 pretreatment in LPS-injured mice, which had a positive effect on LPS-induced gut microbiota dysbacteriosis. Additionally, only Se-P2 promoted an increase in the relative abundance of Lactobacillus, Alistipes, and Roseburia and a decrease in the relative abundance of Akkermansia, Erysipelatoclostridium, and Bacteroides in LPS-injured mice. The changes in gut microbiota were obviously correlated with the changes in metabolites and affected the metabolic pathways of valine, leucine, isoleucine, phenylalanine, tyrosine, and tryptophan biosynthesis and phenylalanine metabolism. This may be one of the key reasons for Se-P2 to exert bioactivity through the microbiota-metabolite axis. Furthermore, Se-biofortification in Se-enriched Cordyceps militaris affected the parental proteins of Se-P2 to modulate mitogen-activated protein kinase, GPI anchored protein, and carbohydrate metabolism, translation, folding, sorting and degradation, which may contribute to the bioactivity of Se-P2. Our study provides information on the effect of Se on selenopeptides in vivo, which further promotes the prospective applications of selenopeptides as dietary supplements.

Caffeine intake during pregnancy is common, while its effect on gut microbiota composition of offspring and the relationship with susceptibility to adult diseases remains unclear. This study aimed to confirm the effects of prenatal caffeine exposure (PCE) on the gut microbiota composition and its metabolites in female offspring rats, and to further elucidate its underlying mechanism and intervention targets in adult non-alcoholic fatty disease (NAFLD). The results showed that the gut microbiota of PCE female offspring at multiple time points from infancy to adolescence were significantly changed with depletion of butyric acid-producing bacteria, leading to a decrease in butyric acid in adulthood. It was also found that PCE female offspring rats were sensitive to NAFLD induced by a postnatal high-fat diet (HFD), which is mainly related to the enhancement of hepatic triglyceride synthesis function. Through mechanism exploration, we found that HFD further reduced the fecal and serum butyric acid levels in the PCE female offspring, which was significantly negatively correlated with hepatic SREBP-1c/FASN mRNA expression and triglyceride level. In vivo and in vitro experiments confirmed that sodium butyrate (NaB) supplementation could reduce hepatic lipid accumulation through MCT1/GPR109A-AMPK, thereby effectively decreasing the susceptibility to NAFLD in the PCE female offspring rats.

Probiotics participate in various physiological activities and contribute to body health. However, their viability and bioefficacy are adversely affected by gastrointestinal harsh conditions, such as gastric acid, bile salts and various enzymes. Fortunately, encapsulation based on various nanomaterials shows tremendous potential to protect probiotics. In this review, we introduced some novel encapsulation technologies involving nanomaterials in view of predesigned stability and viability, selective adhesion, smart release and colonization, and efficacy exertion of encapsulated probiotics. Furthermore, the interactions between encapsulated probiotics and the gastrointestinal tract were summarized and analyzed, with highlighting the regulatory mechanisms of encapsulated probiotics on intestinal mechanical barrier, chemical barrier, biological barrier and immune barrier. This review would benefit the food and pharmaceutical industries in preparation and utilization of multifunctional encapsulated probiotics.

The decline in ovarian estrogen production is known to have detrimental health consequences and negatively affect the quality of life in menopausal women. Increasing estradiol levels is key to preventing disease in menopausal women. In this study, Lactobacillus gasseri CCFM1255 isolated from healthy infants was found to have a positive effect on estradiol production in ovariectomized rats. CYP19, the key enzyme catalysing the conversion of androgens into estrogens, was upregulated in adipose tissue upon CCFM1255 treatment. Untargeted metabolome analysis and targeted metabolite detection were used to identify the key metabolites altered by CCFM1255 treatment. CCFM1255 treatment significantly improved the serum concentration of glutamine (Gln). A significantly positive correlation was observed between serum Gln and estradiol concentrations. CCFM1255 treatment reshaped the structure of the gut microbiome, which was correlated with certain changes in serum metabolite concentrations. These results indicate that the provision of CCFM1255 as a dietary supplement may be an effective strategy to alleviate menopausal symptoms by increasing circulating estradiol.
