Higher Blood Zinc Levels Reduces Risk Of Pneumonia In Nursing Homes

August 10, 2010: 04:45 AM EST
Nursing home residents with normal blood zinc levels were half as likely as those with low zinc concentrations to develop pneumonia, according to a USDA-funded observational study. Unfortunately, a high percentage of residents were found to have low serum (blood) zinc concentrations. An earlier study by the same researchers found that taking a 200 international units (IU) supplement of vitamin E daily for a year lowered the risk of upper respiratory infections by 20 percent. The secondary analysis of data from the same clinical trial showed those with normal zinc status also had fewer new prescriptions for antibiotics, a shorter duration of pneumonia, fewer days of antibiotic use and lower mortality compared to those who had low zinc levels.
