Stainless steel cups are not suitable for drinking water?

Stainless steel cups are not suitable for drinking water? is it true？

Water is the source of life,

It is even more important than food in the metabolic process of the human body.

The more directly related to life, the more cautious you must be when using drinking utensils.

So, what cup do you use to drink water from?

If you choose to use a stainless steel cup to drink water, you should pay attention when buying it, especially for tea drinkers. Previously, it was said on the Internet, “Never use stainless steel cups to make tea! It is toxic.” Making tea with stainless steel will dissolve a large amount of Heavy Metal Chromium – Fact or Rumor?

Under normal use, the amount of chromium precipitation in stainless steel cups that meet national standards is very small, so you don’t need to worry about it affecting your health.

The quality of stainless steel cups varies. The worse the quality of the stainless steel water cup, the more likely it is to be corroded. Because the protective film is destroyed, chromium will be released, especially hexavalent chromium. Hexavalent chromium and its compounds are usually harmful to the human body. At present, the relevant information has been updated, you can check the information website for business news. It manifests itself in three aspects:

1. Damage to the skin

Causes skin ulcers, and can also easily lead to dermatitis, eczema, etc.;

2. Damage to the respiratory system

It causes a lot of damage to the respiratory tract. It is prone to congestion and swelling of the nasal mucosa, and frequent sneezing, which may cause pneumonia, tracheitis and other diseases;

3. Damage to the digestive system

Chromium is a metal element that can cause damage to the intestinal system. If you accidentally eat hexavalent chromium compounds, it can even cause kidney failure in severe cases. Especially for those who have a bad stomach, never use low-quality stainless steel cups to drink tea, juice and other acidic drinks.

How to judge the quality of stainless steel products

1. Use magnets

If you can’t tell whether the cup you bought is qualified, I’ll teach you how to use an ordinary magnet to tell whether the stainless steel is good or bad.

If the magnetism of the stainless steel product is very strong, it proves that it is almost pure iron. Since it is iron and the appearance is so bright, it means that it is an electroplated product, not real stainless steel.

Generally, good stainless steel is non-magnetic. There are also magnetic stainless steels, but the magnetism is relatively weak. On the one hand, this is because the iron content is relatively low, and on the other hand, after the surface is coated, it has the property of blocking magnetism.

2. Use lemon

Pour lemon juice onto the surface of the stainless steel product. After ten minutes, wipe off the lemon juice. If there are obvious traces on the surface of the stainless steel products, it means that the stainless steel products are of poor quality and are easily corroded, thereby releasing chromium and endangering human health.
