Aluminum is a metal substance, which is not a trace element needed by the human body, and the amount of aluminum in food that exceeds the national standard can be harmful to human health.
If excessive consumption of aluminum or aluminum excessive amounts of food consumption, affect the normal metabolism of human body cell, affect a series of biochemical reactions, can cause memory loss, cause the problem of dementia in the elderly. As for children, in the process of growth and intellectual development, excessive consumption of aluminum can seriously affect the intellectual development of children.
In foods with excessive aluminum consumption, aluminum can accumulate in the body continuously, causing pathological changes in the nervous system, interfering with people's thinking, consciousness and memory function, and may lead to dementia. Excessive intake of aluminum may also cause calcium loss in bone, inhibit bone formation, and osteomalacia.
Once the aluminum salts enter the human body, they are first deposited in the brain, which can cause brain damage and cause severe memory loss, which is a characteristic of alzheimer's disease. The researchers, who were involved in the work, said experiments with mice showed that the amount of aluminum in their brains reached measurable levels after just drinking a glass of water treated with aluminum salts. A study of rats found that trace amounts of aluminum mixed in drinking water entered the brain and gradually accumulated there. Researchers study of dementia patients, found that these patients, 30% new brain cortex in aluminum concentrations greater than 4 micrograms per gram (dry weight), patients with brain neurons within the nucleus, the aluminum content is four times that of healthy people, the largest up to 30 times. The researchers believe that, over time, aluminum accumulates in the brain, killing neurons and causing memory loss. 'we've spent our lives drinking aluminum salts and eating foods that contain aluminum,' says one scientist. 'so when we're old, we've built up a lot of aluminum.' He points out that the incidence of alzheimer's disease has risen worldwide in the past 70 years. Aluminum is also used in food emulsifiers, he said.
Aluminum can directly damage the activity of osteoblasts, thereby inhibiting the matrix synthesis of bone. At the same time, the absorption of aluminum by the digestive system leads to the increase of urinary calcium excretion and the deficiency of calcium in the human body. Aluminum accumulates and performs physiological functions in the human body, which can also cause encephalopathy, bone disease, kidney disease and non-iron deficiency anemia.
To prevent the harm of aluminium article there are three main ways: one is the recommended city tap water company in line with the aim of responsible to the people to oneself, do not use aluminum salt [such as potassium aluminium sulfate (KAI (SO4) 2) water purifier; 2 it is as far as possible need not aluminum cooker; 3 it is to eat less food containing aluminium salt additives is more (e.g., Fried dough sticks).
Aluminum is very toxic to human body, and it is toxic to biology. Soluble aluminum compounds are toxic to most plants, and the dissolved aluminum compounds in the water of acidic soil make it difficult for normal crops to grow properly. Usually when the dissolved aluminum reaches 10 to 20PPM, the plant will have an aluminum toxicity. The aluminum in the soil can be combined with soluble phosphate to produce insoluble phosphoric acid, which causes the plant to die without phosphorus. Aluminum also dehydrates plant cells and destroys them. The combination of aluminum and pectin in the cell wall strengthens the crosslinking structure of pectin, which hinders the absorption of water and nutrients. The mineral nutrients such as calcium and phosphorus in plants are closely related. It can inhibit the absorption and accumulation of calcium and phosphorus in general plants, and also affect their absorption and accumulation of elements such as potassium, magnesium, manganese, copper and zinc. Aluminum to aquatic animals also have poison, when pH is about 5, deposition in aluminum hydroxide form within the gills, made it difficult to make oxygen into the blood, fish salt concentration in the body and the imbalance, causes the death of fish. The toxicity of aluminum to aquatic animals is generally 70 micrograms per liter. The increase of aluminum content in the water will result in a large amount of organic matter coagulation, which will cause aquatic animals to die due to lack of nutrition. Aluminium can precipitate phosphorus and seriously threaten the reproduction of aquatic animals.
