Can has the advantages of light weight, small volume, not easily broken, easy to carry, so people favour. But the scientists found that the content of aluminum beverage cans in 3 - 6 times higher than bottled drinks. This is because, in the process of cans, it is inevitable that some local protective coatings not painted, or too thin coating, the inner wall of the cylinder Aluminum Alloy and beverage contact. The aluminum can react with acid to produce elemental aluminum salt and alkali, and the reaction of meta aluminate. This will lead to a gradual increase in the aluminum content of the beverage. The excessive intake of aluminum elements is harmful to human body, the WHO in 1988 formally identified as a food contaminant aluminum, therefore, many developed countries have restricted the production of cans.

Aluminum is eaten by people, basically can not be discharged in vitro, it will always be deposited in the human body. Trace elements in aluminum is not needed by the body, excessive intake will affect the composition of iron and calcium absorption of human body, leading to anemia and osteoporosis, the side effect is mainly manifested as alum can kill brain cells, the early brain atrophy, dementia and other symptoms. China has banned the use of aluminum utensils as early as 1980s.

Excessive intake of aluminum elements will cause harm to the human body to produce the following: Alzheimer's disease; may cause osteoporosis, prone to fracture; immunity; cause non iron deficiency anemia.

In addition, low concentration of aluminum can also produce accumulation, on the nervous system, bone, liver, kidney, heart, immune system, can cause varying degrees of damage.

In summary, the beverage cans should not drink, drink more, especially in children and the poor excretory function strong period of growth and development of the old man, is to drink less better. Usually drink drinks should be as far as possible to choose glass bottles or soft drinks.
