1. Evidence:
The European Union, which has the strictest food safety, has special standards en601 and en602 for aluminum tableware, which limit the content of other impurities and compounds in aluminum tableware. It indicates that aluminum itself is safe. gigaarticle.com
2. Analysis:
It is a lie to talk about toxicity without considering the dose. At the dose of more than 40mg/ kg body weight / day, aluminum began to show toxicity to human body.
This is roughly equivalent to an adult eating an aluminum ring every day. Is it possible? In fact, oral drugs for the treatment of gastric ulcer contain aluminum doses greater than 100mg/ day.
3. Is it harmful for a long time?
Except for a few people who are obviously allergic to aluminum, it is basically harmless.
The harm of excessive intake does not exceed the impact of excessive intake of salt by Chinese people. The same metal ions, aluminum or sodium, will affect the absorption of calcium and iron, only a little. This is the origin of the so-called anemia rumors.
4. What tableware is safe?
If you take the same amount of aluminum, when it starts to be toxic, chromium and nickel are already dead. What about non stick pots?
It is also a synthetic chemical substance that cannot be explained clearly. Its long-term effect needs to be confirmed. Therefore, there is no absolutely safe tableware material.
As long as it is metal tableware, try to avoid or reduce acid-base cooking. The so-called pure iron pot has impurities as well as other harmful metals and ferroalloys.
Lightweight is the biggest advantage, but the cost is not low at all. After all, now pure aluminum ingots are 2w+ a ton.
Moreover, camping is an occasional behavior after all. At the same time, it is easy to form an oxide layer on the surface of pure aluminum, which further reduces the intake of aluminum in contact with food.
Although aluminum alloy tableware is non-toxic, light and durable, long-term use of aluminum alloy tableware will lead to excessive accumulation of aluminum in the human body, accelerate aging, and have adverse effects on people’s memory.
A person who pays more attention to details, indeed, aluminum is a harmful metal, but it doesn’t have to be too hasty. Grasp the principle of one degree. In the use of tools at home, pay attention to the use of aluminum tableware as little as possible to avoid the intake of aluminum in the human body. As long as its aluminum content does not exceed a certain amount, it is harmless to the human body only to contact the skin.
Moreover, products that have been sold offline are basically subject to strict checks and tests before they are sold. Therefore, if it is a wiping mop, you can rest assured to use it.
There is certainly a basis for the fact that the state has not banned aluminum tableware. To say that aluminum is harmful, there must be more than a certain amount
Aluminum is also an essential trace element for human body. Aluminum alloy tableware generally has an oxide film on the surface. When an electric cooker cooks for a short time, contact with water vapor will not cause aluminum harmful to human body to enter the rice. Don’t worry too much.
