Secondhand Smoke Lowers Vitamin C Levels in Children

A new report found that exposure to secondhand smoke could lower the levels of vitamin C in the blood, especially among children, Reuters reported March 6.

The study by Dr. Richard S. Strauss of the University of Medicine and Dentistry at the New Jersey-Robert Wood Johnson Medical School in New Brunswick, looked at 3,000 children between the ages of 4 and 18 who were exposed to passive smoke.

Strauss found that children and adolescents exposed to secondhand smoke had 20 percent less vitamin C in their blood than those not exposed. The low levels were present regardless of how much vitamin C they took in food and multivitamins. Vitamin C protects against heart disease and is needed for growth and development.

The study is published in the March issue of Pediatrics.
