Zinc in food: Why is it important?
Zinc is an essential trace element that plays a key role in the immune system, wound healing, skin health, and metabolism. Since the body cannot produce zinc itself, it must be obtained through the diet or dietary supplements.
What is zinc?
Zinc is involved in more than 300 enzymatic processes, including regulating metabolism, supporting immune defenses, and repairing tissue. Studies show that adequate zinc intake strengthens the immune system, promotes skin health, and supports cell division.

Foods high in zinc
Zinc is found in many foods, with animal products containing the highest concentrations.
Animal-based sources of zinc
- Meat: Beef, pork, and poultry.
- Fish and seafood: Oysters contain up to 20 mg of zinc per 100 g and are among the best natural sources of zinc.
- Dairy products: Cheese, yogurt, and milk contain moderate amounts of zinc.
Study: According to a publication in the Journal of Trace Elements in Medicine and Biology, animal-based sources of zinc are better absorbed because they do not contain phytates. (Trace Elements Source)
Plant-based sources of zinc
- Nuts and seeds: Pumpkin seeds, sunflower seeds, and cashews.
- Legumes: Lentils, chickpeas, and beans.
- Whole grains: Oatmeal, quinoa, and whole-grain bread.
Tip: Plant-based zinc is absorbed less efficiently due to phytic acid. Soaking, sprouting, or fermenting foods can increase bioavailability.
Study: A study in the Nutrients Journal highlights that processing plant-based foods improves zinc absorption. (Nutrients source)
Benefits of zinc
- Strengthening the immune system: Zinc helps fight viruses and infections. A study in Frontiers in Immunology shows that zinc deficiency increases susceptibility to viral infections. (Immunology source)
- Healthy skin and hair: Zinc accelerates wound healing and helps with acne and hair loss. Studies show that zinc reduces inflammatory processes associated with acne. (Dermatology source)
- Boosting fertility: In men, zinc improves sperm quality; in women, it supports hormonal balance.
- Metabolism support: Necessary for carbohydrate, fat, and protein metabolism.
