Zinc is an important nutrient, but get it from food, not supplements, experts say

Zinc is a vital nutrient that plays a crucial role in various bodily functions. From supporting the immune system to promoting wound healing, zinc is essential for maintaining overall health and well-being. While there are zinc supplements available in the market, experts emphasize the importance of obtaining this nutrient through a balanced diet rather than relying solely on supplements. In this article, we will explore the benefits of zinc, its food sources, and why experts recommend getting it from food.

Zinc is an essential mineral required by the body for various biochemical processes. It is involved in over 300 enzymatic reactions and plays a vital role in gene expression, protein synthesis, and cell division. While the body cannot produce zinc on its own, it can be obtained from a variety of food sources.

The Importance of Zinc

Zinc is necessary for the proper functioning of the immune system, as it helps in the development and activation of immune cells. It also acts as an antioxidant, protecting the body’s cells from damage caused by free radicals. Additionally, zinc is involved in the synthesis of DNA, RNA, and proteins, making it crucial for growth and development.

Functions of Zinc in the Body

Zinc has a wide range of functions in the body. It is essential for wound healing, as it promotes cell growth and repair. It also plays a role in maintaining healthy skin, hair, and nails. Zinc is involved in maintaining a sense of taste and smell and supports normal cognitive function. Furthermore, it is necessary for reproductive health in both males and females.

Food Sources of Zinc

Zinc can be obtained from various food sources. Some of the best sources of dietary zinc include:

  • Shellfish (such as oysters, crab, and lobster)
  • Red meat (beef, lamb, and pork)
  • Poultry (chicken and turkey)
  • Legumes (chickpeas, lentils, and beans)
  • Nuts and seeds (cashews, pumpkin seeds, and hemp seeds)
  • Whole grains (wheat, quinoa, and rice)
  • Dairy products (milk, cheese, and yogurt)
  • Dark chocolate

Including these foods in your diet can help ensure an adequate intake of zinc.

Absorption of Zinc

The body’s ability to absorb zinc from food varies depending on several factors. Certain compounds found in plant-based foods, such as phytates and fiber, can inhibit zinc absorption. On the other hand, animal-based sources of zinc are more easily absorbed by the body. To enhance zinc absorption, it is advisable to consume zinc-rich foods along with a balanced diet that includes sources of vitamin C.

The Role of Zinc Supplements

While zinc supplements are available and can be beneficial for individuals with specific deficiencies or medical conditions, experts generally recommend obtaining zinc from food rather than relying solely on supplements. Whole foods provide not only zinc but also a wide array of other essential nutrients that work synergistically for optimal health. Additionally, consuming excessive amounts of zinc through supplements can lead to adverse effects and disrupt the balance of other nutrients in the body.

Risks of Excessive Zinc Intake

It is important to note that excessive zinc intake can have negative health effects. Consuming high doses of zinc supplements for an extended period can interfere with the absorption of other essential minerals like copper and iron. This can lead to deficiencies in these nutrients and potentially cause health problems. Therefore, it is crucial to follow recommended daily intake guidelines and consult with a healthcare professional before starting any supplementation regimen.


Zinc is an essential nutrient with numerous benefits for overall health. While zinc supplements may be necessary in certain cases, experts emphasize the importance of obtaining zinc from a balanced diet. Including a variety of zinc-rich foods in your meals ensures not only an adequate intake of zinc but also provides other essential nutrients vital for optimal health and well-being.
