Aluminum is not a trace element needed by human body, and its absorption capacity is not strong. If you take too much for a long time, it will produce chronic toxic effects after accumulating to a certain amount.

Children's long-term and large-dose consumption of food with excessive aluminum content during their growth and development may cause neurological dysfunction and mental retardation. Excessive aluminum acts on bone tissue, which leads to the loss of calcium deposited in bone, inhibits bone formation and may promote osteoporosis. In addition, aluminum is toxic to hematopoietic system and immune system, and it will also hinder the absorption of elements such as calcium, zinc, iron and magnesium.
