Is it really dangerous nickel?

This micronutrient was discovered in 1751 by Krondstedt, the Swedish minerologist. But no good for the human body from nickel was not found until the 1970s. Later, as it turned out, nickel still needed the body, only in very small quantities. Nickel for a long time did not recognize because it has very high toxicity, that is, it can have serious side effects on health. Thus, additives with additional doses of nickel are rarely required, and as a rule, a person gets enough of it in the usual menu.

What does nickel look like?

Nickel is a metal, which is usually painted in a silvery white color. Nickel is often combined with other metals, forming mixtures, known as alloys. Nickel is contained in the earth's crust, which means that a certain amount of it is found in water, soil, air and food. Most of the nickel in our body comes from foods that contain this trace element. You can also get a dose of nickel as a side effect of tobacco smoking.

Nickel in food

Nickel is found in some food products, but in very small quantities. According to the Center for Disease Control and Prevention, Americans consume about 170 μg of nickel every day, when they eat the usual foods. The foods with the highest concentration of nickel are chocolate, soy, nuts, oatmeal. Tap water and cigarette smoke also contain a small amount of nickel. Coin processing also implies a small amount of nickel, when you take the coins in your hand, nickel penetrates the bloodstream through the skin.

Useful properties of nickel

Nickel is a part of every cell of our body. It plays an important role in the metabolism of certain proteins and can contribute to the production of hormones, lipids and cell membranes. Nickel is also used for our body to convert glucose into energy.

According to the book Healthy Nutrition, Fitness and Sport, a small amount of nickel can help our body form enzymes that accelerate chemical reactions in the body, especially to help in the formation of new nucleic acids and DNA.

Nickel Toxicity

Too much nickel is considered highly toxic and can have negative health effects. The most common side effect of nickel is allergic reactions to it, registered according to the Center for Disease Control. The ingestion of too much nickel in the body can cause gastrointestinal disorders, increased red blood cell levels, renal stress, chronic bronchitis, decreased lung function, and in some cases lung cancer.

Toxic effects of nickel

Drinking water, which has a large amount of nickel, about 250 of its particles per million, can cause problems with the kidneys and blood cells, but this is a rare phenomenon. The inhalation of smoke or dust that contains nickel compounds can occur if you work in hazardous industries or in environmentally unfriendly areas. This can lead to a decrease in lung function, bronchitis and an increased risk of lung cancer and cancer.

Dietary recommendations

A high-food diet that contains nickel can increase the risk of side effects associated with high levels of nickel intake. If you are allergic to nickel, avoid food and jewelry that contains nickel. Currently, there is no recommended daily dose of nickel, however, according to the National Agricultural Library, the upper permissible level of nickel intake is 1 mg in adults.

Small doses of nickel in the body - this is normal, but its increased level can be associated with potentially harmful environmental effects.

Physiological use of nickel

Nickel is important for many animals. For example, rats and chickens need to include nickel in the diet to prevent liver disease. It is not yet known whether nickel deficiency is important for human health. According to the US Information Institute, the low level of nickel in the body is associated with kidney and liver diseases. Nickel can also play a role in the functioning of specialized proteins, known as enzymes.

Nickel allergy

The most common way of negative influence of nickel on the human body is allergic reactions. Allergy to nickel often causes contact dermatitis, which is a rash on the skin. This happens when you touch the nickel. This reaction usually occurs between 12 and 48 hours after you have been exposed to nickel. It can affect people of any age. Your skin can become red, dry and itchy, and sweating can make an allergic reaction to nickel worse. Allergy to nickel can be treated with OTC drugs.

Allergy to nickel manifests as contact dermatitis, usually on the hands. Nickel affects a person from contact with jewelry, buttons, fasteners, cosmetics and detergents, but some foods do contain nickel and can cause an exacerbation if consumed. Most of the nickel-containing foods, except for mussels, are grains, nuts and legumes that have absorbed nickel from the soil. A diet low in nickel can be more healthy and balanced.

Products with low nickel content

It is important to include in the menu sources of food with a low content of nickel and avoid foods with a high content of nickel. Products with low nickel content include beef, ham, poultry, cucumbers, cheese, milk, yogurt, onions, cabbage, spinach, lettuce, corn, pumpkin, carrots, apples, pears and strawberries.

These sources of protein with a high content of saturated fats and cholesterol should be consumed in moderate amounts.

Chocolate / Cocoa powder

According to the US Agency for Toxic Substances and Disease Registry, chocolate is one of the foods with a high nickel content. Bitter sweet chocolate contains a concentration of nickel of 2.6 μg / g, milk chocolate contains a concentration of nickel of 1.2 μg / g and pure cocoa powder contains a nickel concentration of 9.8 μg / g. The nickel content in chocolate is high due to the powerful processing process and constant contact with stainless steel machines.

Cashew

Cashews also contain a relatively high concentration of nickel. The concentration of nickel cashew nuts is 5.1 μg / g. Consumption of cashew nuts can bring health benefits, such as the prevention of gallstones, the development of cardiovascular diseases and the maintenance of bone and muscle health.
