平时出门遇到口渴，大部分人在小卖部随手拿起的可能就是农夫山泉,许多年轻人，家里常备5L或者8L的超大瓶农夫山泉。那么问题来了，农夫山泉可以长期饮用吗？
When going out and encountering thirst, most of people may pick up Nongfu Spring at the commissary. Many young people always have 5L or 8L large bottles of Nongfu Spring at home. So can Nongfu Spring be drunk for a long time?
答案是不可以。农夫山泉属于矿泉水，含有多种对人体有益的物质和游离的二氧化碳，这是有益的。但是，如果长期饮用矿泉水，会影响胃液的分泌和胃的消化机能，还会影响胆汁的形成和分泌，从而导致人体内的酸碱失调。The answer is NO. Nongfu Spring is mineral water, which contains a variety of beneficial substances and free carbon dioxide, which is beneficial. However, if you drink mineral water for a long time, it will affect the secretion of gastric juice and the digestive function of the stomach, as well as the formation and secretion of bile, which will lead to acid-base imbalance in the human body.矿泉水中含有较多的矿物质，过量饮用会使这些矿物质盐刺激肾脏和膀胱，增加肾脏和膀胱的负担。所以患有慢性肾炎、高血压、心脏病及伴有浮肿的病人不宜饮用矿泉水，更不能将矿泉水当作治病的药水服用。Mineral water contains a lot of minerals, excessive drinking of these mineral salts will stimulate the kidneys and bladder and increase the burden on the kidneys and bladder. Therefore, patients suffering from chronic nephritis, high blood pressure, heart disease and edema should not drink mineral water, let alone take mineral water as a potion for curing diseases.适量的钙摄入可以促进人的骨架、牙齿发育，增加细胞的通透性等，但是如果过量补充则会引起高钙血症，使人出现软弱无力、食欲不振、呕吐腹泻等痛苦症状，而且过量的钙可能导致肾结石，所以结石患者要少喝矿泉水。Appropriate calcium intake can promote the development of human skeleton and teeth, increase cell permeability, etc. However, excessive supplementation can cause hypercalcemia, causing painful symptoms such as weakness, loss of appetite, vomiting and diarrhea, and excessive calcium may cause kidney stones, so stone patients should drink less mineral water.
目前市面上的瓶装水分为四大类,我们该如何选择：
There are currently four types of bottled water on the market. How should we choose:纯净水和蒸馏水一般是以城市自来水为水源，采用蒸馏法或其他多层过滤加工制成的饮用水，在将有害物质及微生物去除的同时，也去除了钾、钙、镁等人体所需的矿物质。由于纯净水无任何矿物质，水质偏酸，长期饮用不利于人体健康，应少选为佳。1. Purified water/distilled waterPurified water and distilled water are generally city tap water as the water source, and the drinking water is made by distillation or other multi-layer filtration processing. While removing harmful substances and microorganisms, it also removes potassium, calcium, magnesium and other human needs. Since pure water does not contain any minerals and the water quality is acidic, long-term drinking is not good for human health, so it is better to choose less.矿物质水（又称人造矿化水）是在纯净水中通过人工添加矿物质来改善水的矿物质含量。这样的水虽然增加了部分矿物元素，但是添加的矿物质被人体吸收、利用的情况以及对人体健康的作用如何，尚需进一步研究，应慎重选用。Mineral water (also known as artificial mineralized water) improved the mineral content of water by artificially adding minerals to pure water. Although some mineral elements are added to this kind of water, the absorption and utilization of the added minerals by the human body and the effect on human health require further research so it should be carefully selected.天然水是取自天然水源（地表水或地下水），经过深度过滤、消毒后处理而成。这类水含有微量的矿物质，但含量低于矿泉水，达不到矿泉水国家标准规定的指标，而且其中有些矿物质含量也不稳定，因此称不上是矿泉水，应注意选用。Natural water is taken from natural water sources (surface water or groundwater), and it is processed with deep filtration and disinfection. This type of water contains trace minerals, but the content is lower than mineral water, it cannot meet the indicators specified by the national standards of mineral water, and the content of the minerals is also unstable, so it cannot be called mineral water and should be selected carefully.天然矿物水是从地下深处自然涌出或经人工揭露的未受污染的地下矿水，含有一定量的矿物质、微量元素，其中的矿化质多呈离子状态，容易被人体吸收，某些特定元素对人体健康具有保健作用，应为首选。Natural mineral water is unpolluted underground mineral water that naturally emerges from deep underground or is artificially exposed. It contains a certain amount of minerals and trace elements. Most of the mineral water is in the state of ions and is easily absorbed by the human body. Specific elements have health effects on human health and should be the first choice.
