Zinc, or zinc, is one of the essential minerals for the health of the human body, which plays many vital roles in biological processes. This mineral, which is found in many foods, is necessary for the proper functioning of more than 300 enzymes in the body. Zinc’s properties include boosting the immune system, helping to heal wounds, maintaining healthy skin and hair, and even improving brain function. This vital element not only helps the growth and repair of tissues, but also plays an effective role in maintaining hormonal balance and strengthening the reproductive system. In the following, we will examine the properties of zinc in detail and its tremendous effects on the health of the body.
Properties of zinc
Strengthen the immune system with zinc
One of the most important properties of zinc in the body is strengthening the immune system. This mineral is essential for the proper functioning of immune cells and helps the body effectively fight infections and viruses. Zinc deficiency can reduce the production of lymphocytes, which are key cells in the body’s defense. It has been found in various studies that the consumption of zinc can reduce the duration of a cold and the severity of its symptoms. This effect is due to zinc’s ability to prevent the proliferation of viruses and reduce inflammation. Therefore, getting enough zinc is very important, especially in the cold seasons of the year.
Zinc and its role in wound healing
As a restorative mineral, zinc plays a vital role in the healing process of wounds. This element participates in the production of collagen, which is one of the main components of skin tissue. When injured, the body needs more zinc to speed up the tissue repair process. Therefore, doctors usually recommend that patients with chronic wounds or severe burns get more zinc through diet or supplements. Zinc deficiency can slow down the wound healing process and increase the chance of infection.
Supporting skin and hair health
Zinc plays a key role in maintaining healthy skin and hair. This mineral prevents overactive sebaceous glands and helps regulate sebum production, which is very effective in preventing acne. In addition, zinc also plays a role in preventing hair loss. Zinc deficiency may cause brittle nails, dry skin, and increased hair loss. Consuming zinc-rich foods such as nuts, seeds, and seafood can help maintain beautiful and healthy skin and hair.
The role of zinc in strengthening memory and brain
Another amazing property of zinc is its effect on brain function and memory enhancement. Zinc is involved in the activity of brain synapses, which are responsible for the transmission of nerve messages. Research has shown that zinc deficiency may lead to memory problems and decreased ability to concentrate. In addition, zinc prevents brain damage by reducing oxidative stress in nerve cells. Getting enough zinc through diet or supplements can help improve cognitive function and prevent brain disorders.
The effect of zinc on the reproductive system
Zinc is one of the essential minerals for the health of the reproductive system in men and women. In men, zinc helps to produce testosterone and maintain sperm quality. The lack of this mineral may lead to a decrease in fertility. In women, zinc is also necessary to regulate the menstrual cycle and the functioning of the ovaries. In addition, zinc plays a very important role in the growth and development of the fetus during pregnancy. For this reason, pregnant women should ensure adequate intake of zinc.
Help control blood sugar
Zinc is involved in the metabolism of insulin, the hormone that regulates blood sugar. This mineral helps the body’s cells respond more effectively to insulin and absorb sugar. Research has shown that zinc deficiency can cause insulin resistance and increase the risk of type 2 diabetes. Eating zinc-rich foods like red meat, legumes, and nuts can help control blood sugar.
Maintaining bone health with zinc
Zinc helps maintain bone density and prevent osteoporosis. This mineral plays a role in the process of forming bone cells and maintaining the balance between breaking down and building bones. Zinc deficiency may decrease bone density and increase the risk of fractures. Consuming zinc-rich foods, such as seafood and dairy products, helps maintain healthy bones, especially in middle-aged and old age when bone density declines.
Effects of zinc on heart health
As a strong antioxidant, zinc prevents the oxidation of bad cholesterol (LDL), which is the main cause of heart diseases. This mineral also helps to reduce blood pressure and improve vascular function. Adequate dietary intake of zinc can reduce the risk of heart disease. Consuming fish, seeds, and whole grains are good sources of this mineral.
Food sources rich in zinc
Zinc is found in many foods and is very easy to get through the diet. Food sources rich in zinc include red meat, poultry, fish, shellfish, eggs, legumes, nuts, and seeds. In addition, zinc-fortified cereals can also help increase the intake of this mineral. For people who cannot get enough zinc through their diet, the use of zinc supplements is recommended under the supervision of a doctor.
Disadvantages of zinc
Zinc poisoning
Consuming too much zinc, whether through supplements or food sources, can lead to poisoning. Symptoms of zinc poisoning include nausea, vomiting, diarrhea, and heartburn. These symptoms usually occur when a person consumes more than 40 milligrams of zinc per day, which is much higher than the body’s daily requirement. In more severe cases, zinc poisoning can cause dehydration and impaired kidney function. Consuming very high doses of zinc in the long term may lead to serious damage to the digestive system and may even be life-threatening. Therefore, it is important to adjust the intake of zinc according to the needs of the body under the supervision of a doctor.
Decreased absorption of other minerals
Excessive consumption of zinc can disturb the balance of other minerals in the body. In particular, zinc can reduce the absorption of copper in the body and cause a deficiency of this vital mineral. Copper is essential for the production of red blood cells and maintaining nerve health. Decreased absorption of copper can lead to problems such as anemia, muscle weakness, and neurological disorders. Additionally, zinc can also interfere with iron absorption, which may lower hemoglobin levels in the blood and cause persistent fatigue. These effects emphasize that consuming too much zinc without consulting a doctor can harm the health of the body.
Weakness of the immune system
Although zinc helps boost the immune system, too much of it can have the opposite effect. High doses of zinc may impair the activity of immune cells and make the body more vulnerable to infections and diseases. This situation occurs due to the effect of zinc on the function of white blood cells and the reduction of their production. Research has shown that long-term consumption of high doses of zinc can reduce the body’s ability to fight viruses and bacteria. Therefore, a balanced intake of zinc is essential to maintain the optimal functioning of the immune system.
causing digestive disorders
Consuming zinc in doses higher than the body needs may lead to digestive problems. Symptoms such as nausea, vomiting, and stomach pain are among the most common side effects of consuming too much zinc. These symptoms usually occur when zinc is taken on an empty stomach. In addition, long-term use of zinc supplements may cause gastritis and peptic ulcers. To avoid these problems, it is recommended to take zinc with meals and not to exceed the recommended doses.
Increased risk of prostate cancer
Research has shown that excessive zinc intake may be associated with an increased risk of prostate cancer. Although zinc is essential for the health of the male reproductive system, taking high and long-term doses can have negative effects. This connection may be due to zinc’s effect on hormones and abnormal cell growth. Men who use zinc supplements should carefully monitor their intake to avoid potential risks.
Negative effect on cholesterol
Taking high doses of zinc can disturb the balance of blood lipids. This mineral may lower the level of good cholesterol (HDL) and instead increase the level of bad cholesterol (LDL). An increase in bad cholesterol can increase the risk of cardiovascular diseases and cause blockage of arteries. To avoid these problems, it is important to take zinc in the right amount and according to the doctor’s recommendations.
Nervous and mental problems
Excessive consumption of zinc may cause neurological and mental disorders. High doses of this mineral can lead to problems such as depression, anxiety, and sleep disorders. Zinc interferes with the functioning of neurotransmitters in the brain, and too much of it may lead to chemical imbalances in the brain. In severe cases, this imbalance can impair memory and concentration. Therefore, it is recommended that zinc consumption is always balanced.
Damage to kidneys and liver
Taking very high doses of zinc can put a lot of pressure on the kidneys and liver. These two organs play an important role in eliminating excess substances and regulating the balance of minerals in the body. Long-term consumption of zinc in high amounts may cause the accumulation of this mineral in the body and lead to kidney failure or damage to liver tissues. To avoid these risks, it is best to avoid taking zinc supplements without a doctor’s advice.
