Heavy metal poisoning actually has so many harmful effects on the human body

Heavy metals refer to metals with a density greater than 4.5 g/cubic centimeter, such as lead, copper, zinc, cadmium, etc. Although some of them are essential trace elements for the human body, once the concentration exceeds a certain level, they will cause heavy metal poisoning in the human body. So what harm does heavy metal poisoning have to human health? Most people don't really understand this. In fact, the harm of each heavy metal to the human body is different, but usually they will cause dizziness, headache, insomnia and other phenomena.

Heavy metal poisoning can cause headaches, dizziness, insomnia, forgetfulness, mental disorders, joint pain, stones, cancer and other diseases. It is particularly damaging to the cells, organs, skin, bones and nerves of the digestive and urinary systems. Different heavy metals have different effects on the human body. The most common ones are:

Chromium: can cause numbness of the limbs and mental abnormalities.

Cobalt: Causes radioactive damage to the skin.

Vanadium: damages the heart and lungs, and causes abnormal cholesterol metabolism.

Manganese: Excessive intake can cause hyperthyroidism and damage important organs.

Arsenic: It is one of the components of arsenic trioxide. High levels can cause rapid death. Long-term exposure to small amounts can cause chronic poisoning and cancer.

Cadmium: causes high blood pressure, cardiovascular and cerebrovascular diseases, damages bones, liver and kidneys, and causes renal failure.

Mercury: After ingestion, it sinks directly into the liver and causes great damage to the brain's visual nerves. 0.01 mg of mercury per liter of water can be highly poisonous. Long-term drinking of drinking water containing trace amounts of mercury can cause cumulative poisoning.

Lead: Directly damages human brain cells, especially the nervous system of the fetus. It can cause congenital mental retardation, dementia and brain death in the elderly, and has carcinogenic and mutagenic effects.

Iron: Excessive amounts can damage basic cell components, such as fatty acids, proteins, nucleic acids, etc., leading to an imbalance in other trace elements, especially the need for calcium and magnesium.

Four dietary habits that may lead to heavy metal poisoning

Love to eat offal: Animal offal is prone to the deposition of heavy metals. After unsafe food is eaten by animals, it is metabolized by the offal, and some heavy metals and other harmful substances will be deposited in the offal. Doctors recommend: Eat animal offal no more than once or twice a week, and do not exceed 50 grams each time. In addition, when eating animal offal, it is best to eat more dietary fiber.

Love to drink canned drinks: Cans are made of aluminum alloy, and the inner wall of the can is coated with a layer of organic coating to isolate the aluminum alloy from the beverage. Some unqualified aluminum cans may not be coated with protective coating in some places during the processing process, or the coating is too thin, causing the aluminum alloy on the inner wall of the can to come into contact with the beverage. Over time, aluminum will gradually dissolve into beverages, causing aluminum poisoning. Doctors recommend: It is healthier to drink less canned drinks and instead drink bottled drinks or drink boiled water directly from a cup.

Love to eat seafood: Heavy metals mercury and arsenic are easily deposited in shellfish and marine fish. If you eat seafood for a long time, heavy metals and other toxic substances will accumulate in the body and endanger your health. Doctors recommend: It is best not to eat more than one kind of seafood a day, and the amount should not exceed 100 grams. Try to eat smaller seafood, because larger seafood is higher in the food chain and contains more pollutants.

Frequent consumption of Chinese medicine containing heavy metals: Chinese medicine has always been known for its mildness and few side effects, so some people take it as a daily supplement. However, some Chinese medicines are also toxic. For example, realgar and cinnabar, which are common in Chinese medicine, contain mercury and arsenic. Long-term and excessive consumption of cinnabar and realgar can lead to the accumulation of heavy metals such as mercury and arsenic in the human body, and must be used with caution. Doctor's advice: When taking Chinese medicine, you must follow the doctor's advice to determine whether the medicine is suitable for the patient's constitution and symptoms.

Kind reminder: Heavy metals seriously affect the growth and development of children, so when the baby has developmental problems, timely medical treatment should be sought. Let your baby play in places with fresh air more often and develop correct eating habits.
