Jessica Sachs guides us through the findings of scores of scientists' work that has revised the approach we were taught about "germs" in our childhood. Eating mud, something many of us were at least verbally chastised for, turns out to be a good thing, even a necessity. From birth, the introduction of certain microbes initiate processes the body needs to keep going. For most people today, it's well known that microbes in our tummies are part of the process of digestion. Escherichia coli is known to be a true friend - in controlled numbers and certain strains. What's less known is how many other bacteria the body relies on to get certain jobs done. One of those jobs is keeping the immune system properly tuned. A lazy immune system is unresponsive or unable to react to invasion. An overly ambitious one can turn on its own body and destroy it.
