一.喜喝新茶
由于新茶存放时间短,含有较多的未经氧化的多酚类、醛类及醇类等物质,对人的胃肠黏膜有较强的刺激作用,易诱发胃病。所以新茶宜少喝,存放不足半个月的新茶更应忌喝。

二、喝头遍茶
由于茶叶在栽培与加工过程中受到农药等有害物的污染,茶叶表面总有一定的残留,所以,头遍茶有洗涤作用应弃之不喝。

三、空腹喝茶
空腹喝茶可稀释胃液,降低消化功能,加水吸收率高,致使茶叶中不良成分大量入血,引发头晕、心慌、手脚无力等症状。

四、饭后喝茶
茶叶中含有大量鞣酸,鞣酸可以与食物中的铁元素发生反应,生成难以溶解的新物质,时间一长引起人体缺铁,甚至诱发贫血症。正确的方法是:餐后一小时再喝茶。

五、发烧喝茶
茶叶中含有茶碱,有升高体温的作用,发烧病人喝茶无异于“火上浇油”。

六、溃疡病人喝茶
茶叶中的咖啡因可促进胃酸分泌,升高胃酸浓度,诱发溃疡甚至穿孔。

七、经期喝茶
在月经期间喝茶,特别喝浓茶,可诱发或加重经期综合征。医学专家研究发现,与不喝茶者相比,有喝茶习惯发生经期紧张症几率高出2.4倍,每天喝茶超过4杯者,增加3倍。

八、一成不变
一年四季节令气候不同,喝茶种类宜做相应调整。春季宜喝花茶,花茶可以散发一冬淤积于体内的寒邪,促进人体阳气生发;夏季宜喝绿茶,绿茶性味苦寒,能清热、消暑、解毒、增强肠胃功能,促进消化、防止腹泻、皮肤疮疖感染等;秋季宜喝青茶,青茶不寒不热,能彻底消除体内的余热,恢复味甘性温,使人神清气爽;冬季宜喝红茶,红茶味甘性温,含丰富的蛋白质,有一定滋补功能。

泡绿茶正确的方法:
1.冲泡绿茶时,水温控制在80℃-90℃左右。
2.冲泡茶叶的第一泡不要喝,冲了热水后摇晃一下即可倒掉。
3.冲泡好的茶要在30分钟-60分钟内喝掉,否则茶里的营养成分会变得不安定。
