Because the product surface naturally produces alumina in the production process, forming a protective layer. Of course, the production of professional factories also has special processes to make the alumina layer more durable. Therefore, as long as you don't touch corrosive foods such as acid, alkali and salt and don't soak them for a long time, there will be no aluminum ions.
Long-term use of aluminum pot will lead to aluminum in the body. Aluminum will affect the brain, leading to a decline in IQ and memory. At the same time, long-term use of aluminum pot can easily lead to calcium deficiency anemia. Aluminum will accumulate in the human body, causing pathological changes in the nervous system, interfering with people's thinking, consciousness and memory functions, and may cause dementia in severe cases. When the aluminum content in human body is too high, it will affect the absorption of phosphorus, while the lack of phosphorus will affect the absorption of calcium, leading to the loss of calcium deposited in bone, inhibiting bone formation and osteomalacia.
