Why Is Zinc Important for the Immune System?
Zinc is crucial for several immune functions:
- Boosting White Blood Cell Production: Zinc helps produce and activate white blood cells, the immune system’s warriors.
- Reducing Inflammation: Zinc acts as an antioxidant, lowering inflammation and oxidative stress in the body.
- Enhancing Wound Healing: This mineral aids in tissue repair and regeneration.
- Defending Against Infections: Zinc plays a role in preventing and shortening the duration of illnesses like the common cold and flu.
A deficiency in zinc can leave you vulnerable to frequent infections, delayed healing, and a weakened immune system.
How Much Zinc Do You Need?
The Recommended Dietary Allowance (RDA) for zinc varies based on age and gender:
- Men (19 years and older): 11 mg/day
- Women (19 years and older): 8 mg/day
- Pregnant Women: 11 mg/day
- Breastfeeding Women: 12 mg/day
While supplements are an option, obtaining zinc through food ensures better absorption and minimizes the risk of overconsumption.
