Using silver cups to drink water, there is no obvious benefit, the commercially available silver tableware claims to have sterilization, health and other effects is no scientific basis. Silver ions have a strong bactericidal effect, but silver cutlery silver in the form of monomers, almost insoluble in water, bactericidal effect is minimal, can be regarded as basically no bactericidal effect. In addition, the market sales of silver cups in the production will be mixed with a very small amount of impurities, such as arsenic, cadmium, lead, etc., usually the content is in line with the regulations, will not affect human health. However, if the content of a certain impurity exceeds the upper limit of safety quantification, does not meet national quality standards, such as lead in acidic conditions prone to migration, adulterated with excessive lead elements and long-term use, may cause adverse effects on the human body. Studies have shown that silver itself is an inert metal, chemically very inactive, silver in tableware is not easy to migrate, but also non-toxic. If we can ensure that it is regular pure silver tableware, it will generally have no effect on human health, but also no additional benefits to the human body.
