What are the benefits of zinc?

Zinc plays a vital role in our many body functions, including:

Physical Growth:

People need zinc for physical growth and development. Zinc deficiency in the body can lead to poor growth in children and adolescents.

Zinc for Immune system function:

Our bodies use zinc to build immune system cells which are known as T lymphocytes.

Enzyme function with zinc:

Zinc plays an important role in triggering chemical reactions in the body. These include helping the body use folic acid and create new proteins and DNA.

Eye health:

Zinc deficiency can contribute to the development of eye diseases, including macular degeneration.

Zinc for Wound healing:

Zinc helps to promote healthy skin and mucous membranes, which promotes our body’s wound healing.

Zinc Deficiency Symptoms

In a study, NIH shows that most children and adults consume enough zinc. However, older adults may not be getting the recommended intake.

Some of the symptoms which are associated with zinc deficiency include:

  • Taste and smell are affected
  • Anorexia
  • Diarrhea
  • hair loss
  • weak immune response
  • Impotence
  • poor growth

Doctors do not have an easy blood test to determine if a person has a zinc deficiency. Instead, they often consider a person’s symptoms and average dietary intake when determining if they have a zinc deficiency.

Conversely, a person can also suffer from zinc toxicity from excess zinc supplementation. However, consuming foods that are rich in zinc – even in large amounts – does not usually cause symptoms.

Symptoms of zinc poisoning include:

  • Anorexia
  • Diarrhea
  • headache
  • nausea
  • stomach cramps
  • vomiting

Groups at high risk for zinc deficiency

Alcoholics

30-50% of alcoholics have low levels of zinc because alcohol reduces zinc absorption and increases zinc excretion in the urine.

Vegetarians

The bioavailability of zinc is higher in meat and therefore it is easier to absorb. Furthermore, legumes and whole grains contain phytates that bind zinc and prevent absorption. Vegetarians should aim for 50% more DV of zinc each day to ensure proper levels. For more plant sources of zinc, see lists of zinc-rich plant foods, zinc-rich fruits, and zinc-rich vegetables.

Pregnant and Lactating Women

The developing fetus requires a high amount of zinc, similarly, a large amount of zinc is lost through breast milk after birth.

Older babies who are exclusively breastfed

Babies over 6 months of age should eat age-appropriate foods that provide zinc because the amount in breast milk is no longer sufficient.

People with sickle cell disease

For unknown reasons, 44% of children and 60-70% of adults with sickle cell disease have low zinc levels.

People with gastrointestinal and other diseases

Gastrointestinal surgery, Crohn’s disease, ulcerative colitis, short bowel syndrome and other gastrointestinal diseases can reduce zinc absorption and increase zinc loss from the body.

People who consume high doses of iron supplements

Iron can interfere with zinc absorption, to reduce this effect, iron supplements should be taken between meals to allow zinc to be absorbed properly.

People taking diuretics

Thiazide diuretics such as chlorthalidone (Hygroton) and hydrochlorothiazide (Esidrix, HydroDIURIL) can increase zinc excretion by 60% and, in the long run, deplete body tissues of zinc stores. Be sure to consult your doctor or physician to monitor your zinc level if you are taking these diuretics for an extended period of time, and be sure to eat more zinc-rich foods.

The last few words

After doctors and specialists emphasized the importance of vitamins and certain elements in helping the body to confront the emerging coronavirus that causes (Covid-19), many people around the world rushed to obtain drugs that contain these substances, including (zinc, vitamin C, and omega-3).

Zinc is one of the important elements in the body and plays an important role in many major functions, and it can be obtained from food, and animal products are the best because of their role in providing good amounts of zinc that is easy to absorb.

Zinc can also be obtained from plant sources, but The absorbed amount is not enough for what the body needs due to the effect of some plant compounds on absorption. In these cases, zinc supplements can be taken, taking into account the recommended daily amount to avoid zinc poisoning.
