Ce que c\u2019est<\/h2>\n

Le caf\u00e9 vert est la graine du caf\u00e9ier (Coffea arabica<\/em>), un arbuste de la famille des rubiac\u00e9es originaire d\u2019\u00c9thiopie, avant la torr\u00e9faction. Il contient de la caf\u00e9ine et des acides chlorog\u00e9niques, des polyph\u00e9nols. Les extraits de caf\u00e9 vert sont titr\u00e9s en l\u2019un ou en l\u2019autre.<\/p>\n

Dans un essai japonais<\/a> chez 117 hommes \u00e0 la tension l\u00e9g\u00e8rement \u00e9lev\u00e9e, un extrait soluble de caf\u00e9 vert a fait baisser la tension en 28 jours, d\u2019autant plus que la dose \u00e9tait forte. Une m\u00e9ta-analyse de 2024<\/a> (10 essais, 563 personnes) trouve une baisse moyenne d\u2019environ 3 mm Hg de la tension systolique, plus marqu\u00e9e chez les personnes hypertendues.<\/p>\n
