Here I just talk about the harm of aluminum to the human body.
Aluminum is not an essential element of the human body. When the body lacks aluminum, it will not cause any damage to the human body. On the contrary, aluminum salt can cause human poisoning. As early as 1965, Kako first discovered the brain of aluminum poisoning in the rabbit, and there was an endemic neurofibrillary tangled disease of Alzheimer's disease. It was not until 1973 that he pointed out that the increase in the amount of aluminum in the cerebral cortex of the cat showed that the cat had obvious brain dysfunction, which was to wake the world.
Aluminum is toxic to organisms, especially to humans. Soluble aluminum compounds are toxic to most plants. The dissolved aluminum compounds in the acidic soil make it difficult for ordinary crops to grow normally. Usually when the dissolved aluminum reaches 10-20PPM or more, plants will have aluminum toxic symptoms. In the soil and soluble phosphate aluminum can combine to form insoluble aluminum phosphate, induced by phosphorus deficiency and zhe dead plants. Aluminum also dehydrated the protoplasm of plant cells, then destroyed and died. The combination of aluminum and pectin in the cell wall strengthens the cross-linking structure of pectin and hinders the absorption of water and nutrition by plants. Aluminum is also closely related to mineral nutrients such as calcium and phosphorus in plants. It can inhibit the absorption and accumulation of calcium and phosphorus by common plants, and also affect their absorption and accumulation of elements such as potassium, magnesium, iron, manganese, copper and zinc. Aluminum is also toxic to aquatic animals. When the pH value is about 5, it is deposited in the gills by aluminum hydroxide, which makes oxygen difficult to enter the blood, and makes the fish incompatible with salt, causing the fish to die. The toxicity level of aluminum to aquatic animals is generally 70 micrograms / liter. The increase of aluminum content in water will lead to the aggregation of large amounts of organic matter and the death of aquatic animals due to lack of nutrients. Aluminum can precipitate phosphorus and seriously threaten the reproduction of aquatic animals.
Once the aluminum salt enters the human body, it is first deposited in the brain, which may cause brain damage and cause serious memory loss, which is a characteristic symptom of Alzheimer's disease. The researchers who were involved in the work said experiments on mice showed that the content of aluminum in their brains reached measurable levels after drinking only a cup of water treated with aluminum salts. Studies on rats have found that trace aluminum mixed into drinking water enters rat brain and accumulates gradually. The researchers' study of dementia patients found that the concentration of aluminum in the 30% neocortex areas of these patients was more than 4 micrograms per gram (dry weight), and the content of aluminum in the nucleus of the brain neurons was 4 times as large as that of the healthy people, up to 30 times as large as that of the healthy people. Researchers believe that if aluminum accumulate in the brain over time, it will kill neurons and cause memory loss. One scientist said: we've been drinking aluminum salt water and eating aluminum - containing food all my life, so we have accumulated a lot of aluminum by the time we are very old. He pointed out that the incidence of Alzheimer's disease has increased worldwide over the past 70 years. He says that aluminum is also used in food emulsifiers.
Aluminum can directly damage the activity of osteoblasts, thus inhibiting bone matrix synthesis. At the same time, the absorption of aluminum by digestive system leads to the increase of urinary calcium excretion and the deficiency of calcium content in human body. Aluminum accumulates and acts physiologically in the human body, and it can also lead to encephalopathy, osteopathy, nephropathy and non iron deficiency anemia.
There are three main ways to prevent the harm of aluminum: first, it is suggested that the city water company should not use aluminum salt [KAI (SO4) 2) as a water purifying agent in accordance with the purpose of its own responsibility to the people; two is to use aluminum as a cooking utensil as far as possible; three is to eat less food containing aluminum salt additives (such as oil strips).
So how do we prevent a lot of intrusion of aluminum in everyday life?
An aluminum cooker is used correctly. Because the aluminum cooker, soft and soft, easy to scrape, and can be slow chemical reaction with sugar, salt, acid, alkali, wine and other chemical reactions and overflow more aluminum, thus increasing the opportunity for people to eat aluminum. Therefore, it is not too long to use aluminum cooking utensils to store salt, acid and alkali foods. Do not use aluminum spades, aluminum spoon and other appliances, because they are in the long scraping of stir fry and rice, produce the invisible aluminum chips, which can enter the body with the food entrance. The application of bamboo spoon or non-toxic plastic spoon rice. It is recommended that families with conditioned conditions do not use aluminum cooking utensils, except that they can use stainless steel cooking utensils besides iron pots and casseroles. Because stainless steel products are stable in metal properties and harmless to human body.
No food containing more aluminum. Eat or not eat the use of aluminum containing food additives made of cakes, pastries, bread and biscuit Deep-Fried Dough Sticks, food etc.. Take the fried dough sticks as an example, each oil treaty contains aluminum 10mg, eating two two a day, taking aluminum 600mg a month, which is 10 times of the normal human body's aluminum content. The content of aluminum in tap water is very low, in line with national health and safety standards, can be assured to drink.
Eat healthy food and do fitness activities. On the one hand, we can eat more walnut kernel, sesame, green bean and other brain foods. On the other hand, in order to prevent Alzheimer's disease, we should strengthen the exercise of brain and brain, look at books and newspapers, think more, play chess, talk to people, participate in sports activities suitable for the elderly and so on.
Some substances are contained in the human body, but these substances do not have any effect on the human body. On the contrary, these substances will be harmful to the human body when the content of these substances is high in the human body. Because aluminum products are widely used in life and aluminum salt is widely used to purify water, the aluminum content in the human body is relatively high.
