Zinc

Interestingly, ancient Egyptians used zinc to promote wound healing.  As it turns out, they were right.  But zinc has other benefits too -- so, what role should zinc play in your health regimen?

Zinc is an essential mineral for your overall well-being and the support of a healthy immune system, though researchers have long debated whether or not zinc can help lessen the duration of a cold.  That's because some research shows benefit in that area, while other research doesn't.  But for consumers who see cold-related results when taking zinc tend to be big fans of this supplement.  And although the evidence is not conclusive for fighting a cold, there are reasons why specific populations may benefit from incorporating zinc supplements into their routines.  For example, the elderly appear to be at risk for zinc deficiency and taking a zinc supplement can help fill that gap and work towards improving overall health.  Vegetarians, in particular, may not get enough zinc from food alone.  Some studies indicate that long-term supplementation with zinc may reduce the risk of certain eye diseases.

Be aware that high intakes of zinc can interfere with your body's ability to absorb copper, another mineral essential for proper immune function, so if you are taking a zinc-containing supplement, be sure to follow label directions.

This important mineral is critical for growth and development in general, as well as for the specific development of T-lymphocytes, a type of white blood cell that helps fight infection. Zinc is also required for the action of more than 100 enzymes -- important substances that promote biochemical reactions within the body -- and plays a role in maintaining your senses of taste and smell.

You can also find zinc in the following foods:

• Beans
• Dairy products
• Nuts
• Oysters
• Poultry
• Red meat
• Whole grains

Signs that you aren't getting enough zinc include hair loss, diarrhea, wounds not healing, anemia, eye and skin lesions and loss of appetite. Many of these symptoms are general and can be associated with other medical conditions, so if you're experiencing them, you should talk with your healthcare provider.
