Aluminium in cans harms human body

Cans have the advantages of light weight, small size, not easily broken and easy to carry, so they are favored by people. However, scientists found that aluminum content in cans is 3 to 6 times higher than bottled drinks. This is because during the processing of cans, it is unavoidable that protective coatings are not applied or are too thin in some places, so that the aluminum alloy on the inner wall of the can is in contact with the beverage. The aluminum element can react with acid to form aluminum salt, and can react with alkali to produce metaalumate. This leads to a gradual increase in the amount of aluminum in the beverage. Excessive intake of aluminum is harmful to the human body. The World Health Organization formally established aluminum as a food contaminant in 1988. Therefore, many developed countries have restricted the production of cans.

After being eaten by humans, aluminum cannot be eliminated from the body. It will be deposited in the body forever. Aluminum is not a trace element needed by the human body. Excessive intake can affect the body's absorption of iron, calcium and other components, leading to anemia and osteoporosis. The main manifestation of toxic and side effects is that alum can kill brain cells, causing early brain atrophy. Dementia and other symptoms. China had banned the use of aluminum cutlery as early as the 1980s.

Excessive intake of aluminum can cause the following hazards to the human body: it causes senile dementia; it may cause osteoporosis and is prone to fracture; it causes the body's immune function to decline; leading to non-iron deficiency anemia.

In addition, low concentrations of aluminum can also accumulate, causing damage to the nervous system, bones, liver, kidneys, heart, and immune system.

In summary, canned beverages should not be used for regular drinking and drinking, especially for those children who are in a period of vigorous growth and development, and those who have poor excretion functions. Drink beverages at ordinary times should try to choose glass bottles or soft drinks.
