Pollution threatens us all in a variety of ways. Study after study indicates that increased pollution whether in air, food, or water increases the risks of various diseases. In this study in the Journal of Investigative Medicine, researchers looked at the rates of age-related macular degeneration. They found correlations between nitrogen dioxide and carbon monoxide levels in urban environments with the rate of this blinding eye condition.
Age-related macular degeneration affects adults mainly in the later years, leaving some blind if the disease progresses. The study correlated the rates of these two polluting gases from car exhaust with almost a doubly increased rate of this eye disease. This does not guarantee a cause and effect relationship exists, but it does raise some red flags.
Further research is needed since other risk factors for the eye disease were not considered. Until then, in functional medicine we urge our patients to do their best to limit toxic exposures. Fresh air, organic foods, and clean water go a long way in helping patients live healthier more abundant lives.
