〔健康溫馨提示〕你該飲用哪種酸鹼值的水？
近日，各大品牌的濾水器經常推出可以電解不同酸鹼值的水，微鹼的可以飲用或煮食，據說可以中和過多的胃酸，而微酸的水則不可飲用，只可用以洗臉，聽聞可以去除臉上的面油，但以上的說法是否屬實，還有待商榷。
很多人都知道，足夠的水分可加快新陳代謝，有助將身體的毒素、廢物排出體外。 不過，不同pH值的水會否對身體造成影響？偏酸的水(pH低於7)又會否影響健康？
先說說平常的水，你可能會問：「蒸餾水怎不是中性的？」，沒錯，純水本來就是中性的，但你不能無視空氣中的二氧化碳， 空氣中的二氧化碳可溶於水，令水變成弱酸性。因此淨化水的pH一般會低於7 的，所以其實我們喝了這麼多年的極微酸水，身體有怎麼變化不同？
蒸餾水 vs 鹼性水 vs 酸性水
蒸餾得來的水沒有任何物質和營養。
鹼性水由電解水機製造出來，故稱為電解水。其原理是依據「電化學」與「電解」原理 ，而坊間認為鹼性水可用作治療癌症，但現時未有實質科學研究證實有關講法。另外，也有研究顯示鹼性水能中和胃酸令胃酸倒流的情況改善，但目前需要更多研究支持。
有腎科專科醫生指，一般人飲用pH值偏酸的水，身體會自行調節，但消耗身體能量，危險是腎病患者誤喝偏酸的樽裝水，會令病情惡化。
普遍認為 鹼性水>蒸餾水>酸性水，但我建議選擇飲用不同酸鹼值的水時先了解自己的身體狀況，再自行評斷個人的體質是否合適飲用，如果不了解的話就選擇偏中性的蒸餾水，避免誤飲不適合的水，否則後果可以很嚴重。

Being a biology majored graduate, I do not think that the pH of the food will cause damage to our bodies. Because I think our bodies are very smart, it can mantain the pH of the body very well by homeoatasis. A little change in pH causes organ dysfunction. Only people with illness would exhibit a larger change in pH of the body, is the condition of the body but not the food.
Thank you for your post, but as a scientist i do strongly believe that alkaline water is alkaline simply because it contains more minerals or other things from the water source. And as we all know minerals or trace metals are actually important to our bodies, to provide proper ions for our cellular processes such as cofactors for enzymes. Thats why the general public got the concept of higher pH water is more healthy while weak acid water is bad. Weak acid water here i refer to distilled water acidified by carbon dioxide only. If distilled water is made alkaline by adding sodim hydroxide i sincerely doubt that it does any good to our body, pH is not the reason for the health, what caused the increase in pH is the key factor!
Hmm you give a piece of useful information to us! I would think more before choosing which one!
