Le vin rouge révèle ses bienfaits à Angers
Pourquoi les Français, adeptes du foie gras, du cassoulet et autres spécialités gastronomiques riches en graisses, affichent-ils une des espérances de vie les plus élevées du monde, au lieu de succomber dans la fleur de l'âge, les artères bouchées ? Qualifiée de « paradoxe français » par les Américains, cette énigme trouve - en partie - sa réponse dans le petit verre de vin qui arrose nos repas. Les populations qui se plient à ce rituel risquent moins l'infarctus, ont révélé de nombreuses études croisant habitudes alimentaires et état de santé et ce, en dépit du scepticisme observé dans d'autres laboratoires de recherches. « Un tas d'or »PLoS ONE: Estrogen Receptor Alpha as a Key Target of Red Wine Po
Background A greater reduction in cardiovascular risk and vascular protection associated with diet rich in polyphenols are generally accepted; however, the molecular targets for polyphenols effects remain unknown. Meanwhile evidences in the literature have enlightened, not only structural similarities between estrogens and polyphenols known as phytoestrogens, but also in their vascular effects. We hypothesized that alpha isoform of estrogen receptor (ERα) could be involved in the transduction of the vascular benefits of polyphenols. Methodology/Principal Findings Here, we used ERα deficient mice to show that endothelium-dependent vasorelaxation induced either by red wine polyphenol extract, Provinols™, or delphinidin, an anthocyanin that possesses similar pharmacological profile, is mediated by ERα.
- Henty, VIC Famed for its spectacular minerality, tight acid structure and unique terroir, Seppelt's Drumborg resides at the cutting edge of Australia's modern riesling class, taking the challenge right up to long term classics like Grosset's Polish Hill and Leo Buring's Leonay. Almost colourless, with an icy impression of coolness that restricts its water-tight, stony scents of minerals, quartz, lime and jasmine flower, the 2011 Drumborg's nose does shy away in its infancy, but that's of little concern right now.
