What happens if you eat boogers?

There are several viewpoints on the matter, but according to Dr. Joseph Mercola, eating boogers may actually be good for a person. Dr. Mercola claims that eating one's own boogers helps strengthen a person's immune system.

When the human body is kept away from all bacteria and given antibiotics to kill off viruses, its immune system is unable to build up. Exposure to germs is a pivotal part of developing a strong, healthy immune system that is able to combat disease. According to Dr. Mercola, ingesting one's own boogers does just that and is no different from swallowing the mucus at the back of the throat.
