Many people, especially vegetarians and older adults, might not get enough. A lack of zinc can lead to weak immunity and slow wound healing. It's important for skin health and fighting off infections....
Testing for zinc levels can be beneficial for individuals with symptoms of zinc deficiency, such as hair loss, weakened immunity, and slow wound healing. It’s also important for those with gastrointestinal disorders like Crohn’s disease, which can impair zinc absorption. People with chronic kidney disease, alcohol dependence, and those on long-term use of certain medications that affect zinc absorption or metabolism may also benefit. Additionally, pregnant women, breastfeeding mothers, and vegetarians, who might have higher zinc needs or lower zinc intake, could benefit from such testing to ensure adequate levels for overall health.
Foods high in zinc include meats like beef, pork, and lamb, and seafood such as oysters, crab, and lobster, which are particularly rich sources. Poultry like chicken and turkey, and fish like salmon and sardines also provide good amounts of zinc. For vegetarians or those looking for plant-based sources, legumes like lentils, chickpeas, and beans, nuts and seeds, especially pumpkin seeds and cashews, and whole grains are beneficial.
Zinc supplementation offers several benefits, especially for those with a deficiency. It boosts the immune system, enhancing the body’s ability to fight off infections. Zinc is crucial for wound healing and skin health, helping in the treatment of acne, eczema, and other skin conditions. It supports growth and development, making it important for pregnant women and children. Zinc also plays a role in maintaining eye health and may reduce the risk of age-related macular degeneration. Additionally, it can aid in reducing the duration of colds when taken at the onset of symptoms.
