Are aluminum products harmful to the body?

In our daily lives, we may come into contact with many aluminum products, and sometimes some cooking utensils are also made of aluminum. However, there is a saying that aluminum products can cause certain harm to the body, so they are not suitable for cooking. So, is this statement correct? Are aluminum products harmful to the body? Next, the experts will answer the question.

1. Aluminum is a highly active metal, so the outermost layer of the aluminum products we use is not aluminum, but a thick layer of aluminum oxide. Aluminum oxide is very stable under neutral and weakly acidic (weakly alkaline) conditions. For example, the main component of ruby ​​and sapphire is aluminum oxide, and aluminum oxide also accounts for a large part of the soil. The tap water we usually drink is neutral and slightly acidic, which will not release aluminum ions in aluminum oxide.

2. Aluminum ion is a metal ion that is easily hydrolyzed. Heating and carbon dioxide dissolved in water can cause aluminum ions to precipitate into aluminum hydroxide, so even if aluminum ions exist, it is difficult for them to exist in large quantities in water.

3. Aluminum is one of the elements with the highest content in the earth's crust. It exists in large quantities in nature, so there is no need to be afraid of aluminum. As long as you use aluminum products normally and do not use them to hold acidic or strongly alkaline liquids for a long time, these aluminum products are very safe and the very small amount of aluminum ions they leak will not cause harm to the human body.
