The Head of the heavy metals found naturally in the earth, in rocks, soils, rivers, lakes, sea water and even the air (dust). It has no taste or smell. It is the heaviest of all non-radioactive metals. It is in almost everything you drink, eat and breathe. During the twentieth century has become the Earth covered in a layer of lead through mining and the burning of fossil fuels and combustion of leaded gasoline. Fortunately, have lead in the last 30 years, efforts to reduce contamination accelerated. In a perfect world we would not be exposed to lead at all, because there is no use for lead by the human body. High lead exposure can cause neurological damage and blood pressure. Unfortunately, we do not live in a perfect world. We have “soiled our nest.” However, we are able to manage our exposure limit, despite a baseline that will always exist. And although it always lead in our food, water and air, he had no toxic levels. Our food and water are safe for consumption. It is dangerous aspects of life in danger for our food and drinks, we should be more concerned that the current concentrations of lead.
Index foods high glycemic (simple sugars, little or no dietary fiber), trans fat, and the exploitation of our diets a lot more than the amount of lead in our diet today, and have caused and continue to cause cause more deaths and illnesses that more or never. Obesity, atherosclerosis, heart disease, cancer and diabetes are the result of the high glycemic index foods and trans fats. Ironically, the high glycemic index contain processed foods less lead than complex carbohydrates and whole grain foods. We all know that it is important to focus on a healthy diet of fruits, vegetables and whole grain products, and we must continue to focus on these foods. The reason for the health of whole-grain foods contain more lead than processed foods because the plants from minerals, including lead, from the ground. And, whole grains, with shallow roots, which found the head in a few inches from the ground. Most unprocessed foods (eg whole-grain products) that contain more lead, it can. However, the levels in general are far from being poisonous!
In no way can I say that lead is safe or not a health problem. It is obvious. But lead has decreased gradually because of the cleanup effort in the United States and other countries, the level of contamination and the amount of lead in our food, drinks and water included decreased to levels associated with death or illness.
Another important source of lead is smoking. Five hundred micrograms of lead is given with each inhalation of cigarette, and 1,000 micrograms of lead is in a single pack of cigarettes are included. Most of the lead that is inhaled by smoking, is now expired, but of course, is a relative amount is absorbed through the lungs. A smoker can smoke absorb more lead daily than all combined their food and beverage sources. Although lead exposure to smoke, death and disease is much more realized by all the other toxins in cigarette smoke (which cause oxidative damage) and the toxicity of lead.
For 2500 years people have been working with lead. Utensils, cups, plates and pottery are from historically been manufactured or contain lead. We now know that this is dangerous. Ancient China, dishes and ceramics are lead, which provided a unique brightness glazed. However, the food is absorbed on items such as lead. The food is in contact with these products that contain lead than lead in the food chain. Heat food in jars containing lead increases the absorption of lead. Therefore, what are dishes and plates used to eat and tend to heat.
The actual pollution of our planet came during the 20th Century. From 1920 to 2000, more than 300 million tons of lead was mined and distributed in our environment. It was in the atmosphere by the combustion of leaded gasoline, the burning of fossil fuels (coal distributed), burning rubber, metal (copper and steel) to maintain plants, paint, and the production of improper disposal of batteries, lead pipes, through which our drinking water flows lead in solder used in the manufacture of gaskets keep our food boxes, … and as already mentioned, our kitchen utensils, and glassware.
Tetra-ethyl lead Tetra-and began to put methyl in gasoline in 1923, with billions of tons of lead released into the air exhaust from cars and trucks in all countries of the world. A layer set to lead the entire surface of the earth, sea and land a few inches of the soil contains more lead, with the most contaminated areas of soil along roads and factories. leaded gasoline was removed in 1971 in the United States and in most other countries. Some countries have significantly reduced the level of lead in their essence, and in some countries, particularly in Africa, have no changes and continue to use leaded gasoline.
Plants absorb minerals from the soil. Plants with shallow roots, such as grass, including cereals, to absorb the minerals found within a few inches, where most of the hot metal. It is important, not for food in the vicinity of roads, mines, landfills, land old town or the nearby gardens of old houses, recycling and ammunition factories, because they are grown to eat lead richest soils.
In the last three decades in the United States and many other countries have greatly reduced pollution by lead and cultures are grown in “safe ground.” In 1951, the use of lead paint has set. (Again, it was used because the coating is cheap gloss, lead-free provided it. Some countries such as China, even with lead paint, for this reason.) Although not 100%, plants and grains grown in the United States and other countries responsible for containing “acceptable” or non-toxic levels of lead. The concern driving the contaminated plants remain in countries still using leaded paint and gasoline.
Dirt and soil are 10-100 times the amount of lead that occurs naturally in food. Children under 5 years are more likely to drive because they put objects in their mouths, which have been on the field or in the mud. And all too often the child will be dirt in the mouth. In fact, this habit “dirty”, which led to the discovery that lead was neurotoxic. It was the child that permanent neurological deficits after consumption of large quantities of chips, which coincided with lead paint from the wall and has developed into the mud that can alert the medical community, lead to health risks.
Despite the reduction of lead in our environment and the removal of dirt in our diet as we age, as have a toddler, we eat or drink, breathe and lead all day. The majority of lead in the body is food. But we do all day eliminated. Lead is not absorbed is excreted in the stool ours. Lead is absorbed, eliminated that in the urine, sweat, skin, binds, hair, nails, and gallbladder by the degradation of hemoglobin, which is leading to. For the vast majority of us, the quantity of lead absorbed each day is matched only by the amount of lead removed bets. Toxicity occurs when the amount ingested, the body’s ability to eliminate it exceeds.
Lead is present in our body. It is in our skin, muscles, organs, blood and other soft tissues, but mostly it is in our bone mineralization. We all lead us, the question is, is it poisonous? As we most of our food as well, and how much is acceptable.
As the environment has been cleaned, has reduced the amount of lead in our food and water. In controlled (SAFE) Drinking water lead level is currently limited in the United States to 0.015 ppm (0.010 in California). This is the acceptable level for water, which comes mostly from lead in the plumbing run (and a little that was leached from the soil). However, our food, meat and plants, especially grain products, with the head. Fortunately, the amount of lead in food is now “safe”, it is thought not to cause injury or illness means.
There are some names to measure the lead content, a proportion of lead on all other components of each material, … in terms of parts per million (ppm). One part per million corresponds to one milligram per gram (one thousandth of a gram) or micrograms per gram (1 / 1, 000,000) of equipment. The other unit overall lead in grams or micrograms available depending on quantity. There are also measures for the amount of lead in air and in blood (micrograms per deciliter).
The World Health Organisation (WHO), the “tolerable weekly intake, from food to 1.5 mg (1500 micrograms), corresponding to an intake of lead per day more than 0.2 mg of lead derived set (200 micrograms). Although many parts of the world have not met those standards, most countries like the United States. Therefore, a non-pregnant adults who may consume less than 200 micrograms of lead per day is assured that their food safe.
In the United States, the levels in food range from 0.1 ppm to 0.3 ppm, and therefore the consistent food safety standards of the WHO. An adult American consumes about 1 kg of food (the average), with a lead content of 0.1 to 0.3 ppm in the ‘healthy food’, consumes between 0.1 to 0.3 mg (100 to 300 micrograms) per day. This is our current base, and should not hurt.
As our environment continues to be cleansed, the future of “acceptable level” of lead will be reduced to less than 50 micrograms per day for nonpregnant adults, less for pregnant women, and even less for children.
Meanwhile, it is normal and “safer” than most fruit, vegetables and whole grain products, is consumed more lead. The junk food and sweet drinks (simple carbohydrates) is consumed the least amount of lead is consumed, but the cost of health is more important for those who eat later. The fact is, you are not afraid to eat your fruits, vegetables and whole grains, cereals or meal replacement drinks contain complex carbohydrates and fiber. Your health is of great use to eat these foods, despite the relatively small amount of lead.
The adult body can eliminate 300 micrograms (or more) of lead per day, making it difficult to focus and direct cause harm. Only the high lead exposure leads to neurological problems in children (and fetuses), and blood pressure in adults.
What meal replacement drinks? Health drinks meal replacement have complex carbohydrates and proteins from cereals. This meal replacement beverages with caloric beverages should not improve (no simple sugars and fiber), which are used to increase the weight to be confused in the old and sick people. The same sugars (simple carbohydrates standard) drinks can stress to weight gain, glucose intolerance, and oxidative. It is always best to concentrate on the meal replacement drinks contain complex carbohydrates, fiber, protein and healthy. Meal replacement drinks, which are used to lose weight or maintain include, naturally, a certain amount of lead. This is no different from food. The good quality meal replacement drink is made that less lead than that which contain a normal meal included.
Low-glycemic carbohydrates, whether in food or drinks are caloric increase in trade less fiber, and consequently to a rapid rise in blood sugar and insulin levels. Repeated doping blood sugar and insulin, insulin and glucose intolerance, diabetes, obesity and heart disease. Focus on healthy foods rich in fiber, complex carbohydrates, healthy proteins, will do the opposite. The drink that all the high glycemic carbohydrates-sweet (not fiber) is most likely to fat production and oxidative damage, which incorporates by spiking insulin levels of lead. But what is best for safe levels of lead (less than 100 micrograms per day) by eating low glycemic foods high in fiber and eat a diet high in glycemic index foods? Other foods, smoking, obesity and high glycemic index of the largest share of almost all major chronic degenerative diseases, and today most of the deaths. Lead is not a major factor in the disease process today (except in areas of high contamination).
Since there is a “non-injurious substance” of lead in all foods, quit to not eat fruit, vegetables and cereals (other than in contaminated soil grown) and low glycemic index, high-fiber meal replacement drinks. Suppose that a certain healthy meal replacement drink was 6-7 microgram of lead per serving, and if that person is consuming this drink three times daily for a daily total of 21 micrograms of lead, which is much lower intake of lead as 100-300 micrograms per day average lead again in the average adult American diet. In addition, the same amount of lead, which are easily removed daily, so no harm, and all the benefits!
replace A new way of viewing, a small amount of lead in drinking water, a meal is a relative protection you get higher levels of lead by eating your normal foods!
You can further reduce the intake of lead through the consumption of special allowances. Calcium and vitamin C, but two of the nutrients, the intake of lead blocks in your gut. So make sure you take a good supplement to a healthy level of calcium (at least 1000 mg daily) and vitamin C (at least 1000 mg / day), supplemented with a complete range of pharmaceutical quality nutritional activity guaranteed.
