red wine and health

Xuben Hou, David Rooklin, Hao Fang, Yingkai Zhang
Resveratrol is a natural compound found in red wine that has been suggested to exert its potential health benefit through the activation of SIRT1, a crucial member of the mammalian NAD(+)-dependent deacetylases. SIRT1 has emerged as an attractive therapeutic target for many aging related diseases, however, how its activity can only be activated toward some specific substrates by resveratrol has been poorly understood. Herein, by employing extensive molecular dynamics simulations as well as fragment-centric topographical mapping of binding interfaces, we have clarified current controversies in the literature and elucidated that resveratrol plays an important activation role by stabilizing SIRT1/peptide interactions in a substrate-specific manner...

Neurodegenerative disorders are often life threatening and hired as an economic burden to the health-care system. Nutritional interventions principally involving polyphenols were practiced to arrest or reverse the age-related health disorders. Flavonoids, a class of dietary polyphenols, are rising to superstardom in preventing brain disorders with their potent antioxidant defense mechanism. Quercetin is a ubiquitous flavonoid reported to have all-natural myriad of health benefits. Citrus fruits, apple, onion, parsley, berries, green tea, and red wine comprise the major dietary supplements of quercetin apart from some herbal remedies like Ginkgo biloba...

The traditional Mediterranean diet (MD) is associated with long life and lower prevalence of cardiovascular disease and cancers. The main components of this diet include high intake of fruit, vegetables, red wine, extra virgin olive oil (EVOO) and fish, low intake of dairy and red meat. Olive oil has gained support as a key effector of health benefits and there is evidence that this relates to the polyphenol content. Olive leaf extract (OLE) contains a higher quantity and variety of polyphenols than those found in EVOO...

Wine has been used since the dawn of human civilization. Despite many health benefits, there is still a lot of discussion about the real properties of its components and its actions on cells and molecular interactions. A large part of these issues permeate the fine line between the amount of alcohol that causes problems to organic systems and the amount that could be beneficial for the health. However, even after the process of fermentation, wine conserves different organic compounds from grapes, such as polysaccharides, acids, and phenolic compounds, such as flavonoids and nonflavonoids...

The purpose of the work was to assess the influence of the concentrate of red table wine Saperavi on the cultivated nerve cells exposed to glutamate. The selection of Saperavi as the source of phenolic compounds was not accidental: this type of grapes in the Krasnodar region has the highest content of them - up to 4-5 g/dm3 and more. Polyphenol concentrate was prepared by pre-distillation of ethanol using vacuum, evaporation of red table wine with a rotary vaporizer, with the subsequent lyophilic drying. By the methods of voltammetry and chemiluminescence an antioxidant activity, and a quantity of antioxidants in the concentrate have been determined...

Context • Telomeres are repeated deoxyribonucleic acid (DNA) sequences (TTAGGG) that are located on the 5' ends of chromosomes, and they control the life span of eukaryotic cells. Compelling evidence has shown that the length of a person's life is dictated by the limited number of times that a human cell can divide. The enzyme telomerase has been shown to bind to and extend the length of telomeres. Thus, strategies for activating telomerase may help maintain telomere length and, thus, may lead to improved health during aging...

The increased incidence of cardiovascular diseases (CVDs) has stimulated research for substances that could improve cardiovascular health. Among them, resveratrol (RES), a polyphenolic compound notably present in grapes and red wine, has been involved in the "French paradox". RES is known for its antioxidant and anti-inflammatory properties and for its ability to upregulate endothelial NO synthase (eNOS). RES was able to scavenge (•)OH/O₂(•-) and peroxyl radicals, which can limit the lipid peroxidation processes...

Contamination of food/feedstuffs by mycotoxins is a serious problem worldwide, causing severe economic losses and serious health problems in animals/humans. Deoxynivalenol (DON) is a major mycotoxin contaminant and is known to impair intestinal barrier function. Grapes and red wine are rich in polyphenols, such as resveratrol (RES), which has striking antioxidant and anti-inflammatory activities. RES is a food-derived component; therefore, it may be simultaneously present with DON in the gastrointestinal tract...

Resveratrol is a well-known triphenolic natural product present in red wine. For its contribution to human health, the demand for resveratrol as a food and nutrition supplement has increased significantly. In recent years, the rapid development of synthetic biology has promoted extensive work to increase the production of resveratrol in microbes. However, supplementation of expensive phenylpropanoic precursors was required in current engineered strains. Here, we first utilized the site-specific integration strategy to produce resveratrol in Escherichia coli The genes tal, 4cl and sts were site-specific integrated into the loci of genes tyrR and trpED in the chromosome of E...

Red wines are thought to be one of the major dietary sources of trans-resveratrol. The beneficial effects of t-resveratrol against metabolic disorders have been well characterized, however, red wines also contain various resveratrol derivatives whose health benefits have not been completely elucidated. In this report, we investigated ε-viniferin, a resveratrol dimer, which is present at comparable concentrations to t-resveratrol in red wines, and has higher anti-adipogenesis activity in 3T3-L1 cells. In addition, ε-viniferin was more effective than t-resveratrol in its anti-obesity and anti-inflammatory effects in high-fat diet fed mice...
