Dietary Zinc is an essential mineral that plays a crucial role in various bodily functions. It is important for immune system support, wound healing, and DNA synthesis. Foods rich in zinc include meat, shellfish, legumes, seeds, nuts, dairy products, and whole grains. The recommended daily intake of zinc varies by age and gender, with adult men typically needing about 11 mg and adult women about 8 mg. A deficiency in zinc can lead to symptoms such as weakened immunity, hair loss, and delayed wound healing. It's important to maintain adequate levels through a balanced diet.
