How do people get lead? What foods contain lead? How to eliminate it from the body?

Women's lipsticks also contain lead, and lipsticks and lead-based whitening cosmetics should be avoided during pregnancy.

It is a relatively slow process, and oil is pressed such as popcorn, chips, pencils for elementary school students, canned food, etc. It is not easy to remove, and it is mainly necessary to prevent these **, and to treat the symptoms in addition.

Lead poison can be said to be ubiquitous, the dust inhaled by people walking on the road, the emission of car exhaust, paint, and even the ink and book fragrance when reading all contain lead, as well as all kinds of fried food, and the color glaze in the bowl. Of course, if it does not exceed the standard, it is not a big problem, the method of lead removal is only through the method of dietary therapy, lead can be combined with protein and excreted from the body, and can also contain some inorganic anions or acids such as iodine ions, phosphate ions, molybdate ions, etc., which can be combined and interchangeable with lead, so that lead can be excreted.

Preserved eggs contain lead weight. Small children should not eat it. Poisoning after eating too much.

Lead-shedding foods can be divided into the following categories:

1) Foods rich in vitamin C. Vitamin C combines with lead to form non-toxic salts that are insoluble in water and excreted in the stool. Consume at least 150 vitamin C per day, and those who have symptoms of lead poisoning need to increase to 200, vitamin C is widely found in the leaves of fruits, vegetables and some plants, and sour fruits such as oranges, lemons, pomegranates, hawthorns, peaches, and especially jujubes are the most abundant.

Apples, strawberries, fresh peppers, cabbage, garlic sprouts, sherry red, tomatoes, cauliflower, etc. also contain vitamin C

2) Foods rich in protein and iron. Protein and iron can replace lead and bind to organic matter in tissues, accelerating lead metabolism, and foods containing high-quality protein include eggs, milk and lean meat. Iron-rich leafy greens and fruits include spinach, celery, rape, cherry blossom, amaranth, shepherd's cabbage, tomato, citrus, peach, plum, apricot, pineapple and red dates.

3) Allicin. Allicin in garlic can be combined with lead to become a non-toxic compound, so workers engaged in lead operations eat a small amount of garlic every day than workers who do not eat garlic The incidence of lead poisoning is 60% less, in addition, pectin has the effect of inhibiting lead absorption, and sour milk can reduce lead absorption due to gastrointestinal peristalsis, so it should also be appropriately given to children to eat more.

Measures to prevent lead poisoning:

1) Wash your hands frequently and don't suck your fingers According to statistics, 80-90% of the lead in a child's body is ingested from the digestive tract. Therefore, it is important to help your child wash his hands frequently and not suck his fingers to minimize the "lead intake" caused by this normal behavior.

2) Eat less or no high-lead diets like pine eggs, popcorn, and low-quality canned drinks and foods as little as possible. Do not drink the first section of tap water overnight, turn on the tap water in the morning and let it run for 1-5 minutes, because this water contains high lead content.

3) Eat more foods containing calcium, iron, and zinc In the intestines, calcium, iron, zinc and lead are transported by the same carrier protein in the human body, so there is a competition mechanism with each other. Soy products, meat, eggs and animal liver are rich in calcium, iron and zinc.

4) Avoid contact contamination When using food bags to prevent direct contact between the words, paintings, and trademarks on the food, it is necessary to prevent them from coming into direct contact with the food. Home walls are decorated with paint, or children's toys are painted to prevent paint shaving, because color glazes and paints often contain a lot of lead.

5) Block lead dust pollution Residents living on the side of the road or near industrial areas should frequently wipe off the dust on the surface of tables and chairs with a damp cloth. Food should not be exposed to the environment for a long time. Don't play on the side of the road or stay for long periods of time.

Analysis: Eat vitamin-rich foods, such as dates, black dates and kelp and other seafood, such as vegetables, some leafy vegetables, carrots and other vegetables Many natural foods have certain lead prevention and lead repellent functions, which can promote lead removal or dissolve lead toxins. For example, the protein contained in milk and soy milk can combine with lead to form insoluble substances, and the calcium contained in it can prevent the absorption of lead.

Vitamin C and some nutrients in fruits and vegetables can also prevent lead absorption or reduce lead toxicity. Eat as little as possible foods with high lead content such as Songhua eggs and popcorn made by traditional techniques.

The diet should contain sufficient amounts of high-quality protein, especially those rich in sulfur-containing amino acids (such as cysteine), which is beneficial for reducing lead concentrations in the body and can also reduce the symptoms of poisoning. Insufficient protein can reduce the body's ability to excrete lead, increase lead retention in the body, and increase the body's susceptibility to lead poisoning. Generally, the daily intake of protein should be kilograms of body weight, of which animal protein and legume protein, such as milk, eggs, lean meat, poultry, fish and shrimp, soybeans and soy products, should account for more than 1 2.

Polysaccharide macromolecular substances such as pectin, alginic acid and dietary fiber, whose glycan chains are rich in free -OH and -COOH groups, can be complexed with lead to form a gel that is difficult to absorb, effectively preventing the absorption of lead in the gastrointestinal tract and promoting lead excretion.

Lead is a common metal in our daily life, and we often use it in our daily life, so what things in our lives contain lead? Lead ** net for you to summarize:

1) Soil and dust in the living environment, toys and school utensils, inferior paints and printing inks for home decoration, hot wine and alcohol with lead pots or leaded tin pots, abuse of lead-containing pills or home remedies, etc.

2) Lead in food, certain beverages, low-quality foods, Chinese herbal medicines, etc. Lead in food, such as certain canned foods, where the amount of lead in food increases due to the use of lead to soldering seams; Foods with high lead content are mainly popcorn processed from containers with high lead content, and lead oxide is added to speed up its ripening of pine eggs.

c) Lead in animals and plants. Lead levels in plant-based foods are affected by the amount of lead in soil, fertilizers, pesticides and irrigation water. Lead levels in animal foods are affected by lead levels in feed, pasture, air, and drinking water.

4) Air pollution, such as the exhaust of cars using leaded gasoline and households fueled by coal products (such as briquettes and briquettes), the average level of lead in indoor air is much higher than that in outdoor air.

5) Adults and clothing exposed to lead-containing environment and cross-infection to children, such as traffic booths, printing plants, steel mills, oil refineries, foundries, battery industries and mines, etc. are all hard-hit areas of lead pollution, and many industries have the opportunity to be exposed to lead compounds.

vi) the use of lead-containing glazed porcelain; Use lead-containing cosmetics.

Therefore, it is necessary to pay attention to the prevention of lead poisoning in daily life.

Preserved eggs, popcorn, lead solder canned food, fruit peels and other food packaging that are often exposed to color printing, paints, lead-containing cosmetics, hair dyes, lead-contaminated clothing, car exhaust, and lead-containing drugs; Light candles that contain lead, especially scented and slow-burning candles, etc., which will also carry lead to effectively remove lead: First, eat more foods rich in vitamin C. You can eat more fruits with a sour taste, such as lemon, pomegranate, hawthorn, kiwifruit, especially sour dates, which are the most abundant.

Apples, strawberries, fresh peppers, cabbage, tomatoes, etc., also contain vitamin C. The second is to eat more foods rich in protein and iron. Protein and iron can replace lead and combine with organic matter in tissues to accelerate lead metabolism, so children should be given more eggs, milk and lean meat.

The third is to supplement allicin. The allicin in garlic can be combined with lead to become non-toxic compounds.

puffed foods, fried foods, popcorn, pine eggs, contaminated seafood;

Color printed food packaging, paints, lead-containing cosmetics, hair dyes, lead-contaminated clothing, automobile exhaust, and lead-containing candles, especially scented and slow-burning candles, all have a relatively high lead content.

There are those contaminated foods in life that are easy to have high lead content, and some foods will be mixed into the pot during processing, which will also make the processed food contain too much lead, and the popcorn and preserved eggs that people usually eat are common foods with high lead content.

1. Puffed food.

Puffed foods are very common, such as French fries, snow rice crackers, shrimp chips, popcorn, etc., and are loved by many children because they are delicious. However, puffed food should not be eaten too much.

Because puffed food passes through metal pipes during processing, and metal pipes contain lead, lead may contaminate these puffed foods during the production process and end up being eaten by children and falling into their stomachs.

Second, Songhua eggs.

Songhua eggs are also called "preserved eggs", which are usually eaten directly or cold dressed.

In the production process of the previous Songhua eggs, a certain amount of lead oxide will be added, which is commonly known as lead dan, which can form insoluble lead on the eggshell, which is deposited on the eggshell and egg membrane, and naturally there will be residues when eating.

3. Canned food.

The production process and packaging of canned food contain a certain amount of lead, especially after the cans are opened, if they cannot be eaten in time, the food residues will corrode the sealing place of the cans, so that the free solder lead will be mixed into the food, and it will enter the human body when it is eaten again.

Canned food can not be eaten without eating, and most of the nutrients are lost during processing, so it is better to eat fresh food directly.

1. Popcorn and pine eggs.

It should be noted that some products are now advertised as "lead-free Songhua eggs", in which the lead content is not equal to zero, but lower than the corresponding national standard, and it is also not suitable for large quantities. In particular, in some places, popcorn made by the local method and preserved eggs pickled by the local method often contain dozens of times the lead content of the national food hygiene standard. The inside of the tin can of popcorn is coated with a layer of lead or tin-lead alloy, and when the tin can is heated, a portion of the lead gets into the popcorn that rolls in it.

Preserved eggs are made by mixing soda ash, lime, salt and gold corn starch (lead oxide) in a certain proportion and wrapping them outside the duck (chicken) eggs. The lead in raw gold starch can seep into duck (chicken) eggs during the long curing process. These two foods should not be eaten by children.

2. Fried French fries, bad moon cakes (due to poor production process, lead content will exceed the standard in the production process of compression mold), canned food, and offshore seafood are polluted by the environment and have a high lead content.

3. Shellfish, red shrimp, lettuce, sunflower, cabbage, and beer are all relatively high.

4. The vegetables planted around the smelter or the vegetables grown on both sides of the highway are polluted by automobile exhaust (containing tetraethyl lead) and also contain high lead, so the edible vegetables should be thoroughly cleaned;

5. There is also a large amount of lead in the food that is held for a long time in tin plates, lead pots, colored glazed pottery and other utensils, and children should not eat.

For example, lead-contaminated food (caused by using lead containers), shellfish, red shrimp, sunflowers, lettuce, kale, preserved eggs, popcorn, vegetables grown around the smelter, alcoholic beverages - beer, french fries made with undesirable dyes, undesirable mooncakes (due to poor production process, lead content will exceed the standard during the stamping process), etc.
