体内含有过多矿物质的水会给人体造成不必要的负担，而且有的矿物质人体不一定能吸收，如果长期积聚体内，会直接影响人体健康。
Water containing too much minerals in the body will cause unnecessary burden to the human body, and some minerals may not be absorbed by the human body, if accumulated in the body for a long time, it will directly affect human health.
但是纯净水短时间内能够帮助排泄人体内的毒素，长期饮用时可能会导致体内铅的含量超标。因为钙和铅在人体中是竞争关系，一方增多，另一方就会减少，反之，一方减少，另一方就会增多，纯净水中没有钙，人体就会吸收大量的铅，从而导致人体内含铅量超标。
But pure water can help excrete toxins in the human body in a short time, and may lead to excessive lead content in the body when drinking for a long time. Because calcium and lead are competitive in the human body, one side increases, the other side decreases, on the contrary, one side decreases, the other side increases. Without calcium in pure water, the human body will absorb a large amount of lead, leading to excessive lead content in the human body.
过滤纯净水的逆渗透膜虽然去除了水中的细菌杂质，但也把水中的对人体有益的微量元素过滤掉了，长期饮用会导人体的微量元素缺乏，引起少年儿童发育不良,引起老年人的各种微量元素缺乏症。
Although the reverse osmosis membrane filters purified water to remove bacterial impurities in water, it also filters out the beneficial trace elements in water to human body. Long-term drinking will lead to the lack of trace elements in human body, resulting in the development of young children and the deficiency of various trace elements in the elderly.
