1, the harm of heavy metals
The harm of heavy metals to human body is various, and the harm of each heavy metal to human body is different. Generally speaking, the common heavy metals are lead, mercury, chromium, arsenic and aluminum. Lead is toxic in heavy metal pollution, so it is difficult to metabolize after entering the body, accumulate in the human body, damage brain cells, easily lead to fetal congenital mental retardation, and easily lead to dementia in middle-aged and elderly people.
The harm of heavy metals to human body is various.
If heavy metals enter the human body and stay on the skin, it will cause skin pigmentation and abnormal stratum corneum. However, heavy metals are mainly metabolized in the liver and kidney, which will cause visceral poisoning after entering the viscera. For example, mercury can cause liver poisoning, and arsenic can cause renal insufficiency.
2, eating these can detoxify.
(1) kelp
Kelp is a kind of seaweed, which has many health-care functions, such as losing weight, relaxing bowels, regulating the three highs, and supplementing iodine and calcium. Here, we focus on its role in heavy money.
First of all, seaweed gum in kelp has the function of regulating arteriosclerosis and preventing human body from absorbing heavy metals. It can form gel in human intestines, adsorb toxins such as heavy metals, and help the human body detoxify. Therefore, kelp is also known as the scavenger of gastrointestinal tract.
Secondly, kelp has anti-oxidation and anti-cancer effects, and its sodium alginate will combine with heavy metals strontium and cadmium and be excreted, thus avoiding the carcinogenicity of these metals.
Algae gum in kelp can regulate arteriosclerosis and prevent human body from absorbing heavy metals.
(2) Carrots
Carrots are also one of the essential foods for discharging heavy metals. In daily life, we all know that carrots can supplement vitamin A, beautify the skin and protect the eyes, but the pectin in carrots has been ignored by everyone.
First of all, carrots contain a lot of pectin, which belongs to a kind of soluble dietary fiber. After entering the human body, it can combine with mercury, reduce the content of mercury ions in the blood and excrete them. Therefore, if you want to have healthy liver and kidney, then carrots are essential substances.
Secondly, carrots are also beneficial to the health of human intestines, which is the largest gathering place for bacteria and toxins. Eating carrots regularly can proliferate intestinal beneficial bacteria, protect intestinal mucosa and reduce the harm of heavy metals and free radicals to human body.
In addition, if you want to use β -carotene in carrots, you need to cook it, because β -carotene mainly exists in the cell wall of carrots, and the cell wall of carrots is mainly composed of wood fibers, and carotene can be absorbed and utilized by the human body after cooking.
(3) Milk
With the development of industrial level, there are more and more children with lead poisoning in China, and about 40% of urban children have lead exceeding the standard. Lead removal is not a one-off event, and it needs long-term persistence to be effective.
Protein and iron can combine with organic substances in human tissues to form soluble substances instead of lead, and accelerate the metabolism of lead, so supplementing high-quality protein can play a role in expelling lead. Although protein in milk is not the highest, protein in milk is more easily absorbed and utilized by human body, thus playing a role in discharging lead.
In addition, iron supplementation is also a necessary work to discharge lead, so iron supplementation is also a method to discharge lead. It is best to choose vegetables containing iron, such as spinach and fungus.
(4) Auricularia auricula
Everyone has heard that Auricularia auricula can detoxify, but Auricularia auricula can not expel the dust from the lungs, but can absorb the dust from the gastrointestinal tract. The colloid in auricularia auricula can adsorb the dust in the intestine, stimulate the peristalsis of the intestine, and play the role of dust removal and heavy metal discharge.
Auricularia auricula can not expel the dust from the lungs, but can absorb the dust from the gastrointestinal tract.
In addition, the plasma protein in pig blood has a similar effect after digestion, so pig blood and fungus can discharge heavy metals and dust, but not the lungs, but the stomach.
3. High content of heavy metals
(1) Seafood: Seafood is the star of a healthy diet, with delicious taste and rich nutrition, which can prevent cardiovascular diseases and improve mood and memory. But at the same time, the safety of seafood can not be ignored. Due to the spread of pollution, shellfish and marine fish have become the largest sources of heavy metals such as mercury and arsenic, so if seafood is eaten for a long time, toxic and harmful substances such as heavy metals will accumulate in the body and endanger health.
(2) Chinese medicine: Chinese medicine has always been known for its mild side effects. So some people take Chinese medicine as a daily supplement and eat nothing. However, some traditional Chinese medicines aim at fighting poison with poison, but their toxicity is low. For example, realgar and cinnabar, which are common in traditional Chinese medicine, contain mercury and arsenic. Long-term and large-scale use of cinnabar and realgar will lead to the accumulation of heavy metals such as mercury and arsenic in human body, causing serious liver and kidney damage.
(3) Animal viscera: Although animal viscera has unique nutrients, there are many heavy metal deposits. Because poultry are fed with industrial feed, these feeds are uncertain. Once animals eat unsafe food, such as animal feed, and the water they drink is polluted by heavy metals such as cadmium, it will be metabolized by internal organs, and some harmful substances such as heavy metals will be deposited in internal organs. The Health Department of Hubei Province once announced the monitoring situation of food pollutants in Hubei Province: the cadmium content in the kidneys of animals in Hubei Province exceeded the national standard value 100 times. In addition to cadmium, animal viscera may also contain lead, and those heavy metals left in viscera will be transferred to you and become your health killer.
(4) Preserved eggs: When making preserved eggs, there is something called Mimi monk in the auxiliary materials wrapped outside the fresh eggs, and its chemical composition is lead oxide. Adding lead oxide can promote ingredients to penetrate into eggs evenly and quickly, and also can make preserved eggs solidify quickly and shell easily. However, in the process of placing, these lead oxides gradually penetrated into the eggs.
(5) Beverage can: The can is made of aluminum alloy, and the inner wall of the can is coated with a layer of organic paint to isolate the aluminum alloy from the beverage. In the process of dealing with some unqualified aluminum cans, it is very likely that some places are not coated with protective coating or coated too thin, which leads to the contact between aluminum alloy on the inner wall of the cans and drinks. Over time, aluminum will gradually blend into it, especially when the beverage in the can is acidic or alkaline. According to the investigation of 22 kinds of drinks by researchers, the aluminum content in canned food is higher, which is 3 ~ 6 times higher than that in bottled food.
