Zinc protects nerve cells and maintains the balance of neurotransmitters, thereby improving memory and cognitive ability and helping to prevent age-related cognitive problems.
Zinc for Ear Health
Zinc is an important element for ear health, involved in maintaining the function of the auditory system. Although it is a trace mineral, the effect of zinc on hearing is very strong, can protect the ear from damaging factors and improve hearing.
Improve hearing
Zinc can help maintain the nerve cells' function in the ear, especially the cells of the organ Corti - which converts sound into nerve signals. Zinc deficiency can weaken the activity of these cells, leading to hearing loss.
Support prevention of tinnitus
Research shows that zinc can reduce symptoms of tinnitus, soothe discomfort, and improve the ability to regenerate ear cells, helping reduce the disease's frequency and severity.
Protects against oxidative damage
Zinc is a powerful antioxidant that protects the ears from oxidative damage and reduces the risk of hearing loss caused by environmental factors such as loud noise.
Dietary Sources of Zinc
Zinc is an essential mineral that the body cannot produce alone. Therefore, dietary zinc supplementation is extremely important for maintaining overall health. Zinc-rich food sources can be found in animal and plant foods.
Animal foods
Foods such as red meat and seafood, especially oysters and shrimp, are rich sources of zinc. Beef and lamb also contain high amounts of zinc, which makes this mineral easily absorbed by the body. Milk and dairy products such as cheese also contribute to zinc supplementation.
Plant foods
In addition to animal sources, zinc is present in many plant foods, including nuts, beans, and whole grains. However, the absorption of zinc from plants can be affected by inhibitors such as phytate found in some foods.
Supplements
Taking a supplement may be a reasonable option for those who cannot get enough zinc through their daily diet. Supplements in pill or powder form make it easy to get zinc into the body, especially for those who are vegetarian or vegan.
Zinc deficiency
Zinc deficiency is a common nutritional problem, especially in people with an unbalanced diet or those with high zinc requirements. This mineral is essential in many physiological processes, so a zinc deficiency can lead to serious health consequences.
Symptoms of zinc deficiency
Zinc deficiency can manifest through symptoms such as a weakened immune system, susceptibility to infection, slow wound healing, and hair loss. People with zinc deficiency may also experience problems with taste and smell, making food taste bland and difficult to enjoy.
People at risk of zinc deficiency
People on strict vegetarian diets, growing children, and pregnant and lactating women are all at high risk of zinc deficiency. These groups must pay special attention to zinc supplementation to maintain optimal health.
Long-term effects
Suppose zinc deficiency is not corrected in time. In that case, it can lead to more serious problems such as stunted growth, reduced fertility, and even neurological and psychological problems, especially in children and the elderly.
How to Incorporate Zinc into Your Diet
Including zinc in your daily diet is a simple but important way to maintain optimal health. Although a trace mineral, zinc plays a huge role in many physiological functions and protects the body from disease.
Zinc-Rich Foods
One of the easiest ways to get zinc is through food. Seafood such as oysters, shrimp, and crab are rich in zinc, while red meat such as beef and lamb are also excellent sources. If you are a vegetarian, legumes, nuts, and whole grains provide significant amounts of zinc, although it is important to note that the absorption of zinc from plants can be affected by factors such as phytate.
Take a Supplement
Zinc supplements may be an effective solution for those whose diets are deficient in zinc or who have increased needs, such as pregnant women or children. However, supplementation should be considered and consulted with a doctor, especially when using high doses.
