s aluminum harmful to human health?
Although many people know that aluminum is harmful to the human body, the reason for the damage to the human body is not very clear, so so far aluminum products still occupy an important position in the family life.
Aluminum, in the environment of human life, especially in the plants growing in acid soil, is very high in content, and in addition to its extensive industrial and living uses, it is very closely related to people's life.
In recent years, researchers have found that aluminum can significantly reduce the content of norepinephrine, dopamine and 5 hydroxytryptamine in the brain and block the neurotransmitter conduction, resulting in a decline in the learning and memory ability. This conclusion has made a scientific explanation for Alzheimer's disease and mental retardation caused by aluminum. At the same time, they found that the combination of aluminum and citric acid can promote the absorption of aluminum by the gastrointestinal tract and easily enter the brain tissue through the blood brain barrier, which interferes with the conduction and normal metabolism of the nerve, and can accumulate in the bone tissue and make the bone decalcified.
The study also revealed that, regardless of the dose, the activity of the enzyme in the hepatocytes and the renal proximal convoluted tubules was denatured, resulting in a decrease in the activity of succinic dehydrogenase and ATPase, which was important to the metabolism, and thus seriously interfered with the cycle of the three carboxylic acid. Ultrastructural observation also confirmed that the mitochondria appeared ruptured, dissolved and collapsed in mitochondria of hepatocytes and kidneys. This indicates that aluminum has the most significant effect on the liver and kidney. In addition, aluminum can also affect the normal metabolism of myocardium and cause structural damage.
Another important finding of researchers is the adverse effects of aluminum on immune function. The experiment shows that aluminum can obviously reduce the transformation ability of T lymphocyte and inhibit the function of antibody forming cells and macrophages, which leads to the decrease of immune ability and the increase of susceptibility to disease. Because the accumulation of aluminum in the body is long-term, although there is little obvious toxic symptoms in the short term, with the increase of the volume of aluminum accumulation in the body, it will eventually lead to symptoms related to brain, heart, liver and kidney function damage.
