Questioner: Hello!

When it comes to eating bowls, I think the most important thing is whether the bowl you use is safe or not. Porcelain tableware has various shapes, is delicate and smooth, has bright colors and is easy to clean. It is the first choice for most families to buy tableware.

However, the colored glaze on the ceramic surface may become a health killer.

Lead, mercury, radium, cadmium, etc. in colored glazes are all harmful elements to the body.

The radioactive element radium kills white blood cells.

Cadmium, lead and mercury are all heavy metals. Cadmium and lead can cause poisoning of the liver or other internal organs, and mercury can cause cirrhosis of the liver and kidneys.

When using unqualified ceramic products, these harmful substances will dissolve and enter the human body with food, which will cause chronic poisoning over time.

At the same time, we should also pay attention to the clay used for making ceramics. Low-quality clay contains more microorganisms and harmful substances, which can harm human health even if it is not glazed.

When purchasing ceramic tableware, you must choose a regular market, and do not buy low-quality products without official manufacturers.

Don't buy ceramic tableware that is too brightly colored.

In order to make the colors brighter, manufacturers will add some heavy metal additives to the glaze. Therefore, the brighter the color of the tableware, the easier it is for heavy metals to exceed the standard.

Stainless steel is an iron-chromium alloy with a chromium content of no less than 13%. Chromium is harmful to the human body because of its ions, especially high-valent chromium ions.

The chromium on tableware is in a metallic state, and chromium is a very stable metal that is not easy to corrode. General acids will not react with it. This is also the reason why tableware is chromium-plated. Iron will rust if used.

In addition, the more chromium, the better (this is generally true, now that technology has developed, there are many other things in stainless steel).

Therefore, it is basically safe to use stainless steel tableware.

When using aluminum tableware, it is not advisable to use it with iron tableware. Aluminum tableware often has aluminum shavings falling off. When exposed to acid or alkaline substances, aluminum ions can form into the food, and then enter the human body with the food.

Research has found that excessive accumulation of aluminum in the human body can cause mental decline, memory decline, and Alzheimer's disease. Therefore, try not to use aluminum tableware, and even if you use it, avoid contact with acidic and alkaline substances.
