It is unfortunate that most people think that bacteria are a bad thing, when in fact, only a very small portion of them cause diseases. The rest are either harmless or beneficial to us.
Certain bacteria can affect our health in a positive way because they are essential to the proper function of our digestive tract. If we did not have certain "friendly" bacteria in our digestive systems, we would not be able to digest our food properly and then we might become sick, malnourished, or even die.
The other important role that bacteria play, in my opinion, is one that is not well understood or recognized. Most soil is full of bacteria and when they do their job properly, they break down complex organic molecules so that the plants that grow in the soil have an easier job of absorbing nutrients. Many of our fruits and vegetables are grown in fertilized fields with lots of pesticides, so most of the bacteria are gone. And, as a result, our crops are no longer as nutritious as they were a long time ago when all food was grown naturally, organically, without pesticides and fertilizers. If you are not sure that this is true, then ask someone who may know why the FDA has recently increased the daily recommended allowances of fruits and vegetables. I am sure it is because our fruits and vegetables do not contain the same nutritional content as they had long ago, as nature intended.
