營養師妙法 飲酒唔傷肝 防醉孖寶芝士酸瓜

07/09/2006

【專案組報道】不少上班一族經常要「摸酒杯底傾生意」,或者喜歡在公餘到酒吧飲酒紓壓,然而飲太多酒不但會令人即時嘔吐及胃抽筋,更會對身體造成傷害,包括增加患胃癌及肝癌的機會,有打工仔便因每周要應酬四、五晚,結果患有脂肪肝和肝酵素上升。營養師指出,經常飲酒的人士應透過不同方法降低飲酒的分量及減慢吸收酒精速度,盡量避免飲醉或飲酒太多,減少對身體的傷害。
酒精進入體內會先被胃部吸收,然後由肝臟釋放酵素分解,期間身體亦會分泌水分稀釋,由於每個人所製造的酵素量不同,故分解酒精的速度會因人而異。VNS營養健康中心註冊營養師詹兆州指出,身體分解和排走酒精時,會減慢消化其他食物的速度,容易令人體積聚脂肪,形成脂肪肝問題,而部分胃病或胃潰瘍患者若空肚飲酒,則會加重病情,甚至提高患上胃癌的機會。

該中心一位三十三歲的男病人便因工作需要,每周平均有四至五晚要飲酒應酬,每次會飲兩至三支紅酒或烈酒,其體重指標(BMI)達三十五,嚴重超出正常標準,一般亞洲男性的指標為二十三。他接受身體檢查後更發現患有脂肪肝,肝酵素亦較正常人高出三倍。

為免身體被酒精拖垮,該名男病人其後嘗試用綠茶溝酒,藉以減少酒精的分量及減慢身體吸收速度,令宿醉機會大減,加上控制日常飲食及多做運動,結果成功減肥六十磅,而肝酵素亦回復正常。

蛋白質助分解酒精
人體每小時約可分解十克酒精,因此男士每次最多可飲用含三十至四十克酒精分量的飲品,女性的上限則約十至二十克,而不同的酒類酒精含量有異,如每一百毫升紅酒便有十二至十五克酒精。詹兆州提醒市民盡量避免每日飲酒,每周飲酒日數不應超過五日,更不要一次過飲太多。

部分人因工作需要無可避免要飲酒,詹兆州為他們提供「防醉貼士」,減低酒精的破壞力,包括飲酒前吃芝士、牛油及牛奶等含豐富蛋白質的食物,令酒精較易分解;而飲酒期間食用含醋的食物亦有助稀釋酒精,如酸瓜、白雲鳳爪等,但就要忌吃花生、蝦條等油分較高的小食;同時,市民亦可在酒中混入無糖或低熱量的綠茶、果汁等飲品,稀釋酒精分量。

另外,酒量較淺的人則要避免飲用有氣的酒類。詹兆州解釋,啤酒、香檳等有氣酒類含有二氧化碳,可增加胃部對酒精的吸收,令人更易醉倒。
