Article
Four catechins including (−)-epicatechin (EC), (−)-epicatechin gallate (ECG), (−)-epigallocatechin (EGC) and (−)-epigallocatechin gallate (EGCG) were conjugated onto chitosan (CS) molecules via ascorbate radical mediated reaction, producing EC-g-CS, ECG-g-CS, EGC-g-CS and EGCG-g-CS. The four catechin-g-CSs were individually blended with CS to devel...

Black tea is a healthy and popular tea beverage. However, its main bioactive compounds (theaflavins and thearubigins) are not easily absorbed. The aim of this study was to investigate the modulation of intestinal microbiota by the nonabsorptive components of Keemun black tea (KBT) and Dianhong black tea (DBT), and fructooligosaccharide (FOS) was se...

The chemical compositions of black teas differ greatly and may have different health benefits; however, systematic investigations into such benefits are lacking. Here, the chemical profiles of Keemun black tea (KBT) and Dianhong black tea (DBT), two common categories of tea in China, were analyzed, and their lipid-lowering effects in male C57BL/6 m...

Mol. Nutr. Food Res. 2021, 65, 202100626 DOI: 10.1002/mnfr.202100626 Daily consumption of green tea prevents Aβ formation and alleviates cognitive impairment in 5XFAD mice. The neurotoxicity is attenuated by inhibition of APP cleavage pathways, suppression of glial cell activation, and a reduction of synapse loss. This is reported by Feng Gao, Xiao...
Article
Scope: The consumption of green tea is considered to be associated with a lower incidence of neurodegenerative diseases. In the present study, we investigated the role of amyloid precursor protein cleavage, glial cell activation, neuroinflammation and synaptic alterations in the protective effects of green tea against the amyloid β (Aβ) accumulati...

In this study, conjugates of whey protein isolate (WPI) and four polyphenols (epigallocatechin gallate [EGCG], quercetin [QC], apigenin [AG], and naringenin [NG]) were prepared through free-radical grafting. The results for polyphenol binding equivalents and content of free amino and sulfhydryl groups as well as those from sodium dodecyl sulfate–po...

Higher selenium status has been shown to improve the clinical outcome of infections caused by a range of evolutionally diverse viruses, including SARS-CoV-2. However, the impact of SARS-CoV-2 on host-cell selenoproteins remains elusive. The present study investigated the influence of SARS-CoV-2 on expression of selenoprotein mRNAs in Vero cells. SA...
Article
In this study, cassava starch aldehyde was functionalized with catechin through acid catalyzed condensation reaction. The structural characterization, stability and antioxidant activity of starch aldehyde-catechin conjugates were investigated. Thin layer chromatography revealed the conjugates did not contain free catechin. UV–vis spectra of the con...
Article
Green tea polyphenol epigallocatechin-3-gallate (EGCG) may help prevent metabolic syndrome and nonalcoholic fatty liver disease (NAFLD). However, the underlying mechanisms of its protective effects are complicated and remain unclear. With the gut–liver axis theory as a foundation, the present study investigated the effects of EGCG on intestinal muc...

A significant, positive association between selenium status and COVID-19 prognosis has recently been identified. The present study investigated the influence of SARS-CoV-2 on host selenoproteins which mediate many beneficial actions of selenium. We found that SARS-CoV-2 suppressed mRNA expression of selenoproteins associated with ferroptosis (GPX4)...
Article
This study investigated the effects of L-theanine supplementation on the colonic mucosa injury in C57BL/6J male mice treated with dextran sulfate sodium (DSS)-induced colitis. Treatment with L-theanine significantly decreased the disease activity index and ameliorated the inflammation-associated pathological damage in colon length, as well as the h...

Green tea extract (GTE) was fed to laying hens to determine its effects on lipid metabolism and egg production in the hens and the fatty acid composition in the egg yolk. Laying hens (288; 30-wk-old) were subjected to dietary treatments of GTE at a dose of 0%, 0.1%, or 0.3% (w/w) for 8 wk. In the hens, dietary GTE significantly decreased the levels...

Cardiovascular diseases have overtaken cancers as the number one cause of death. Hypertension is the most dangerous factor linked to deaths caused by cardiovascular diseases. Many researchers have reported that tea has anti-hypertensive effects in animals and humans. The aim of this review is to update the information on the anti-hypertensive effec...
Article
Objective: To investigate and compare the effects of two common dietary phytosterols, stigmasterol and β-sitosterol, in altering lipid metabolism and attenuating nonalcoholic fatty liver disease (NAFLD). Methods: Stigmasterol and β-sitosterol were administered to mice at 0.4% in a high-fat western-style diet (HFWD) for 17 weeks. Results: Stigm...

Theanine, a unique bioactive constituent from tea (Camellia sinensis) leaves, is widely used as a functional ingredient and dietary supplement. To evaluate the anti-inflammatory and hepatoprotective effects of theanine and its molecular mechanism, the lipopolysaccharide (LPS)-induced inflammation mouse model was employed in this study. The survival...
Article
Thermal stress evokes heat shock response and activates hypothalamic-pituitaryadrenal (HPA) axis. Additionally, liver injury is an important adverse effect of thermal stress. Considering the anti-stress effects of theanine, an amino acid found in tea plants, we hypothesized that theanine may protect against heat stress. Mice were administered intra...

Summer-autumn tea leaf (SATL) is a waste tea plant resource which is not commonly used in tea industry due to its bitter and astringent taste. This study evaluated the effects of SATL-supplemented diet on broiler immune status. Accordingly, broilers were divided into control group and 3 SATL supplemented groups (0.5, 1.0, and 2.0%). The growth perf...

Scope: The tea polyphenol (-)-epigallocatechin-3-gallate (EGCG) has been shown to ameliorate metabolic abnormalities and fatty liver. The present study investigated the mechanisms of actions of EGCG on bile acid homeostasis and lipid metabolism. Methods: Male C57BL/6J mice were fed a low-fat diet, a high-fat western-style diet or a high-fat west...

Our previous results showed that green tea polyphenols (GTPs) significantly altered the expression of lipid-metabolizing genes in the liver of chickens. However, the underlying mechanism was not elucidated. In this study, we further characterized how GTPs influence AMP-activated protein kinase (AMPK) in the regulation of hepatic fat metabolism. Thi...

Alcohol intake is a major risk factor for the pathogenesis of alcoholic liver diseases. Accumulating evidence suggests that green tea protects against alcoholic liver injury, however, the underlying mechanisms remain unclear. The present study investigated the role of endothelial nitric oxide synthase (eNOS) in the protective effects of green tea a...
Article
Tea, a popular beverage made from leaves of the plant Camellia sinensis, has been shown to reduce body weight, alleviate metabolic syndrome, and prevent diabetes and cardiovascular diseases in animal models and humans. Such beneficial effects have generally been observed in most human studies when the level of tea consumption was 3 to 4 cups (600-9...
Article
A growing body of evidence showed that tea has anti-hyperglycemia and anti-diabetes effects during recent years. Tea may exert beneficial effects on decreasing blood glucose and ameliorating insulin resistance by (i) suppressing carbohydrates absorption, (ii) stimulating glucose metabolism, and (iii) alleviating the oxidative stress. Furthermore, i...
