Zinc May Boost Immunity

Getting enough zinc may help protect the elderly from serious infections.  New research showed 30% of nursing home residents had a zinc deficiency (blood levels less than 70 mcg/deciliter).  Those with low zinc had a significantly higher risk of pneumonia.  Zinc is important to our immune system  It improves the fucntion of T cells, white blood cells that target and destroy bacterial and viral invaders.  Zinc supplementation increased the number and effectiveness of the T cells.  Check with your doctor or pharmacist before supplementing.  Food sources include meat, shellfish, nuts, pumpkin seeds and beans.
