How to avoid excessive intake of heavy metal aluminum
Aluminum is not a trace element required by the human body. It is added as an additive in foods and has an effect of improving flavor. The source of aluminum in everyday foods is either from food additives or comes from the packaging materials, and aluminum is also produced in some foods with alum.
Excessive aluminum causes physical discomfort
Now, aluminum pots and pots with a single chemical composition have rarely been used by families. However, the phenomenon of excessive aluminum in the human body is still worrying. So, what impact does aluminum have on human health? Where does the excess aluminum come from? How to avoid excessive aluminum in life?
From the health point of view, we can not lack some trace elements in our body, such as sodium, magnesium, iron, potassium, calcium, etc., many people mention it again and kindly, but also think of ways to add. But for aluminum, it seems that we don’t need it because we don’t need it. At present, the national food safety risk assessment results show that aluminum is gradually eroding our health, and it has been dealing with us for a long time. Today, aluminum, officially entered our sight.
In 1989, the World Health Organization formally proposed that excessive intake of aluminum would be harmful to human health. It is proposed that the daily intake of aluminum for adults is 4 mg, which is equivalent to only the aluminum content of an oil. Aluminum is not an essential trace element. The normal adult body contains 45-150 mg aluminum, an average of about 100 mg. In fact, the daily intake of aluminum from the general diet of the gastrointestinal tract is approximately 10 mg, and the absorption rate is 0.1%, most of which is excreted in the faeces.
A trace of aluminum that enters the body, normal people also have the ability to excrete through the kidneys and other excretory organs. However, in recent years, studies have found that this protective effect of the intestinal wall is not very perfect. When people take in too much aluminum, they will enter more into human tissues, and it is also difficult to excrete quickly, and thus deposit in various organs. Inside.
Excessive intake of aluminum is detrimental to the brain, bones, liver, spleen, kidneys, etc. There are mainly three aspects: First, it will cause a massive loss of calcium in the body, resulting in osteoporosis; Second, the brain nerve Injury results in a decrease in memory and intelligence. Third, it inhibits the activity of pepsin and impedes the body's digestion and absorption. It also causes loss of appetite and indigestion, affecting intestinal absorption of zinc, iron, and calcium.
In addition to puffed foods, fans, fritters, certain chemical baking agents, and flours with flour and strong gluten may cause excessive aluminum intake. In terms of packaging materials, aluminum pans, aluminum lunch boxes, and aluminum kettles are used to hold When food is used, it is possible to dissolve aluminum. It is best not to use aluminum products to hold acidic, alkaline and salty foods. Do not store foods in aluminum boxes or aluminum pans for long periods of time. It is worth mentioning that cans made of aluminum alloy, in general, the safety of cans and beverages and other food contact with the inner wall will be coated with a protective coating, but in the process of processing, it is inevitable that some places protective coating is not painted , Or painted too thin, so that the inner wall of the tank aluminum alloy and beverage contact, which will lead to gradual increase in the content of aluminum in beverages. Therefore, canned beverages should not be often drink, drink more, especially in the growth and development of children and poor excretion of the elderly, it is better to drink less. Drink beverages at ordinary times should try to choose glass bottles or soft drinks.
So, how do we avoid excessive intake of aluminum metal in our daily lives?
It's better to eat cans
Aluminum is not a trace element required by the human body. It is added as an additive in foods and has an effect of improving flavor. The source of aluminum in everyday foods is either from food additives or comes from the packaging materials, and aluminum is also produced in some foods with alum.
According to reports, in addition to puffed foods, fans, fried dough sticks, certain chemical baking agents, steamed bread flour, etc., can cause excessive aluminum intake; in terms of packaging materials, aluminum pans, aluminum lunch boxes, aluminum pots, etc. When filling foods, it is possible to dissolve aluminum. It is better not to use aluminum products to hold acidic, alkaline and salty foods. Do not store foods in aluminum boxes or aluminum pans for long periods of time. It is worth mentioning that cans made of aluminum alloy, in general, the safety of cans and beverages and other food contact with the inner wall will be coated with a protective coating, but in the process of processing, it is inevitable that some places protective coating is not painted , Or painted too thin, so that the inner wall of the tank aluminum alloy and beverage contact, which will lead to gradual increase in the content of aluminum in beverages.

Drink beverages at ordinary times should try to choose glass bottles or soft drinks.
Usually eat some foods containing vitamin C, or supplementation of selenium trace elements, can help row aluminum. Of course, the most important thing is balanced nutrition and improved metabolism.
