Aluminium and human health

Packaging material is one of the three main application areas of aluminum (transportation industry, construction industry and packaging industry). In 2006, the world's primary aluminum output was 33970kt, among which the amount of packaging industry accounted for 18.5%, developed countries accounted for more than 22%, and the proportion of quasi-developed countries and regions, developing countries and regions is correspondingly lower.

More than 90 percent of the aluminum consumed by the packaging industry is used to package food, beverages, cigarettes, cosmetics and other products related to the human body.

It is necessary to introduce the relationship between aluminium and human health in the light of available information.

Several medical studies and media reports over the past 47 years have suggested a possible link between aluminum and AD (Alzheimer's disease, Alzheimer's disease) because of the presence of unusually long concentrations of aluminum in the brain tissue of patients with such symptoms.

In many cases, however, these studies lead to the opposite conclusion.

The debate has spawned a lot of international scientific research.

Since the turn of the century (since about 2000), medical scientific research has tended to show no causal link between aluminum and Alzheimer's disease.

"There is no evidence that aluminium is a major cause of Alzheimers disease," the WHO said in a subsequent report.

Aluminum does not cause symptoms of the disease in any species, including humans."

The WORLD Health Organization also says there is no scientific evidence that higher levels of aluminum in older people's drinking water increase the risk of Alzheimer's disease or accelerate its onset.

Although most of the aluminum we consume comes from food, less than 1 percent of it is absorbed by the human gastrointestinal system.

The aluminum content of vegetables and fruits depends on the soil in which they grow.

On average, there are 1mg to 7.4mg of aluminum per kilogram of vegetables, only 0.012mg to 0.15mg/L in milk, and even less in soda cans.

Aluminium salts are often added to food preservatives, colours and starter cultures. Aluminium salts can also be used as an ingredient in starter cultures.

The United States Food and Drug Administration and the European Economic Community have strict limits and controls on the amount of aluminum salt additives that can be added.

As the daily intake of aluminium depends on dietary habits (e.g. the proportion of fresh to processed foods) and food sources, there is considerable variation among countries (regions).

Alcan doctors estimate that europeans consume about 5mg/d, while north americans consume much more, about 20mg/d.

Aluminium was originally used mainly in the manufacture of cookware and kitchenware.

Today, aluminum products used in food and beverages are coated with a protective coating to protect them from direct contact. Unprotected aluminum cooking utensils and utensils can be corroded by foods with high acid and salt content (tomatoes, lemons, etc.). Aluminum packaging can also encounter a similar situation.

In 2001 the Council of the European Communities recommended that labels be placed on unprotected aluminium packages as a reminder to consumers.

The protective layer falls off or incomplete aluminum cooking utensils and appliances had better not be used, when the aluminum scrap sold.

Most antacids contain aluminum hydroxide, which can reach up to 500mg in a single dose, 50 times the daily intake.

The medical community has not found any aluminum-related side effects in stomach patients who have been taking the drugs for a long time.

Aluminum phosphate can be added to most vaccines to increase their potency.

In 2002, the World Health Organization said in a report that "the use of such vaccines is safe and poses no risk."

Aluminum chlorate, about 20%, is often added to most fragrances to inhibit perspiration.

Long-term studies have shown no side effects from the use of these fragrances.

Aluminum packaging is safe for food and drink and is not harmful to living organisms.

Aluminum is a good packaging material for food, beverage, medicine, cosmetics and all kinds of articles used by human beings. Its application will be more and more extensive and the dosage will increase year by year. Aluminum has become one of the indispensable packaging materials for human survival and improvement of life quality.
