Many people say that aluminum is very unfriendly to the human body, will damage human brain cells, so the fritters are included in the harmful food, aluminum pressure cooker is also thought to be able to cause Alzheimer's disease. In fact, aluminum is not a terrible substance, belongs to the human body in the trace elements of a kind, but also involved in human life activities. Discussing toxicity depends on the dose, and it is important to know that eating too much of the common sodium salt can increase the risk of developing high blood pressure. And if aluminum accumulates in the body, it does affect the health of a person's bones and nervous system, according to current research.

Aluminum has been linked to osteochondrosis and encephalopathy in some studies. Aluminum intake, if excessive, can cause bone damage and deformation through the role of calcium, phosphorus and vitamin D, chondromalacia, osteoporosis and so on. However, the international authority comprehensive dementia research, and combined with epidemiological survey evidence, that through food and water and other channels of intake of aluminum, and dementia does not have a clear correlation.

In the case of pressure cookers, aluminum cookware is inevitably added to the cooking oil, salt, vinegar and other seasonings, plus high temperatures, spatulas and aluminum pots and pans collision and other conditions, may make the "aluminum" component to a certain extent to be released, generating substances harmful to the human body. But now few families use aluminum pressure cooker. Aluminum heat resistance, stability are poor, so it has long been replaced.

So the claim that aluminum pots cause Alzheimer's is unfounded, but excessive intake of aluminum can cause other damage to the body, so aluminum cookware should be used sparingly.
