Whether aluminum is an essential trace element for human body is still inconclusive. In fact, no cases of aluminum disease have been found. People ingest about 65,438+00-65,438+08 mg of aluminum from their diet every day, most of which is excreted with feces through the digestive tract, and a small part is accumulated in testicles, kidneys, spleen, muscles, bones and brain tissues. It has always been thought that aluminum has little effect on human health. However, in patients with Alzheimer's disease or mental disorders, the aluminum content in the brain is 10-30 times higher than that in normal people. Further studies have confirmed that high aluminum content in food will lead to early aging. The accumulation of aluminum in the brain will lead to the degeneration of cranial nerves, memory decline, intelligence and personality will also be affected, and even Alzheimer's disease will occur. When the aluminum accumulation in the body exceeds 5- 16 times of the normal value, it can inhibit the absorption of phosphorus in the intestine and interfere with the normal metabolism of calcium and phosphorus in the body.

Toxicity analysis of aluminum: aluminum generally enters the human body through the use of food, drinking water, drugs and aluminum cookers, and stays in the brain, lungs, liver, bones and testicles. If the human body accumulates too much aluminum, it will do harm to brain tissue and intellectual development. In order to prevent aluminum poisoning, aluminum containers and cookers are generally coated with a layer of non-toxic paint, so that drinks or food do not directly contact aluminum. Also pay attention to not using or using less aluminum-containing initiators and fixatives to avoid taking aluminum-containing drugs for a long time, such as "Weishuping". Because a certain amount of alum (potassium aluminum alum) is added to the fritters, it is better to eat less.

The natural toxicity of aluminum is very weak, and aluminum in food is easy to form insoluble precipitate with phosphoric acid compounds, which is not easy to be absorbed by human body; At the same time, the gastrointestinal tract of normal people has a barrier effect on aluminum, which can prevent excessive aluminum from entering the body. Therefore, as long as proper attention is paid, there is no need to worry too much about the toxicity of aluminum.
