Aluminum ions will be released when the stainless steel pan is heated, is it harmful to the human body?


As the name suggests, stainless steel is not easy to rust. It is a common food container in the home. In addition to being durable and easy to clean, it is not easy to have odor residues that affect food. Therefore, many lunch boxes on the market are made of stainless steel. However, many articles on the Internet mention that stainless steel contains manganese. We are afraid that we will also eat manganese in the process of eating, causing health risks.

In response to this doubt, today we are going to refute the rumors. In fact, stainless steel is a heat-resistant inert material. It is used to hold general food and is not easy to dissolve harmful substances. For manganese, the relevant standards for the dissolution test are specially formulated.

Stainless steel will not rust at all? wrong!

Consumers who purchase stainless steel kitchenware are more or less familiar with 200 series, 300 series and 400 series products. Different series contain different metal ratios, which will affect the anti-rust effect. The higher the manganese content, the better the anti-rust effect. Not good (different ratio of metal composition in stainless steel). Generally speaking, stainless steel is divided into 201, 430, 304, and 316 types, and edible utensils must be made of 304316 stainless steel.

In addition, in fact, manganese is a trace mineral necessary for the normal metabolism of the human body. Even a lack of manganese in the human body may cause problems such as osteoporosis and growth retardation.

However, if taken in excess, it can cause nervous system-related diseases.

What we don't need to worry about is that excess manganese is usually excreted within a few days, and manganese does not cause cancer or reproductive toxicity, so there will be no food safety issues when using such stainless steel containers under normal conditions, unless the utensils If it is rusted or damaged, it is recommended to stop using it.

Aluminum pot heating releases aluminum ions, fearing that people will suffer from Alzheimer's disease?

Aluminum products are also one of the common materials for pots and pans. It is rumored on the Internet that aluminum ions are released by heating aluminum pots. The long-term accumulation of aluminum ions in the body may cause dementia. Let me also clarify that it is wrong! Some experts took samples of commercially available aluminum food containers for experiments and found that there is indeed a small amount of aluminum dissolved, but because aluminum is inadvertently absorbed in the digestive tract, it will not cause harm to the human body.

It is a return of innocence to the aluminum pots.

do you know? It turns out that many natural vegetables and fruits contain trace amounts of aluminum, such as potatoes, spinach, and tea, which contain relatively large amounts. The aluminum content of other common foods is usually less than 5ppm. It can be seen that aluminum is ubiquitous in the natural environment.

In addition to being widely used in industrial and cooking pots and utensils, aluminum cans and aluminum foil bags are also commonly used in packaged foods. Although cooking and aluminum packaging will increase the aluminum content to a greater or lesser extent, experiments have shown that aluminum is The rate of oral absorption is generally less than 1%, and there is no report showing that oral intake of aluminum will cause acute poisoning, so you can rest assured.

Stainless steel pots are preferred, and aluminum pots should not be cooked for too long

We appeal that although heating with aluminum pots will not cause harm to the human body, it is still recommended to use stainless steel pots and food containers. If you use aluminum pots to cook, the time should not be too long, and try not to use aluminum containers to store and cook acidic food. to ensure food safety.
