怎么喝水最科學(xué)健康-

1、經(jīng)過(guò)一夜的睡眠,人體會(huì)從呼吸、皮膚、尿液中消耗大量水分,處于缺水狀態(tài)。因此,清晨第一杯水就顯得尤為重要,不僅能有效補(bǔ)水,還可以調(diào)節(jié)腸胃、清掃體內(nèi)環(huán)境。別看早起喝水是件小事,未必每個(gè)人都知道怎么喝才健康,以下幾種飲品就要謹(jǐn)慎選擇。隔夜茶。沖泡好的茶水若放置時(shí)間過(guò)久,其中微量的氨基酸、糖類(lèi)等物質(zhì)會(huì)成為細(xì)菌、霉菌滋生的養(yǎng)分,不僅如此,茶水中所含的茶多酚、維生素等營(yíng)養(yǎng)成分也會(huì)因放置時(shí)間過(guò)久,而發(fā)生氧化反應(yīng),導(dǎo)致茶水中所含的抗氧化成分下降,令其營(yíng)養(yǎng)和保健價(jià)值大打折扣。因此,起床后,昨晚泡的茶不宜繼續(xù)喝。淡鹽水。淡鹽水之所以被人們用作清晨第一杯水,主要因?yàn)槠淠芫徑獗忝?在首都醫(yī)科大學(xué)附屬北京友誼醫(yī)院營(yíng)養(yǎng)科

2、主任洪忠新看來(lái),治療便秘光靠喝水是解決不了的,而是要通過(guò)飲食的合理調(diào)整?，F(xiàn)代人鈉攝入量本來(lái)就過(guò)多,在身體不缺少鹽的情況下再喝淡鹽水,會(huì)增加鹽的攝入,反而讓人覺(jué)得口干舌燥。有高血壓、心腦血管疾病、腎功能異常的人更不要將淡鹽水作為起床后的第一杯水,因?yàn)樵绯渴侨梭w血壓升高的第一個(gè)高峰,喝鹽水會(huì)使血壓更高。蜂蜜水。有人認(rèn)為早起喝一杯蜂蜜水有利于緩解便秘,但空腹喝并不適合。“蜂蜜中含有大量果糖和葡萄糖,會(huì)升高血糖,沖擊食欲,影響早餐攝入?！焙橹倚抡f(shuō)。另外,蜂蜜中的果糖要經(jīng)過(guò)代謝轉(zhuǎn)化為葡萄糖才能被人體吸收利用,這樣就失去了清晨第一杯水清掃體內(nèi)廢棄物的作用,蜂蜜的營(yíng)養(yǎng)物質(zhì)也不能被有效吸收。因此,起床后不要空

3、腹喝蜂蜜水,可以先喝一杯溫白開(kāi)水,十分鐘之后再喝蜂蜜水,也可以把蜂蜜作為早餐,抹在面包上一起吃。果汁。不少女性喜歡晨起喝一杯鮮榨果汁養(yǎng)顏,這種做法并不可取。一是因?yàn)楣?空腹喝會(huì)沖擊食欲,吃不下早餐。二是人體喜歡溫暖的環(huán)境,尤其是早晨,如果吃了涼東西,會(huì)刺激腸胃,影響消化吸收。碳酸飲料。碳酸飲料除了不能提供早起人體所需要的水分,在代謝中還會(huì)加速鈣的排出,以及增加機(jī)體對(duì)水分的需求,早晨最好不要喝。“溫白開(kāi)水是清晨第一杯的最佳選擇?！焙橹倚赂嬖V記者,白開(kāi)水沒(méi)有任何熱量,不用消化就能被人體吸收,不僅能有效補(bǔ)充體內(nèi)水分,還可以讓血液迅速得到稀釋,促進(jìn)血液循環(huán),讓人更快地清醒過(guò)來(lái)。清晨第一杯水應(yīng)空腹
