Just a reminder about bacteria, fungi and other organisms in our body. We are full of them. It is estimated that in our digestive system we have about four pounds of these organisms. Remember they are microscopic organisms. It is difficult to even conceive of four pounds of them. They live off of us but It is not a one way street. We play host to them and they help to keep us healthy.
They help us digest our food. They help regulate our immune system and they help keep our brain, heart and other organs healthy.
However, if the mix of good and bad organisms gets out of balance this can make us sick. Diseases such as irritable bowel syndrome, cardiovascular disease and possibly Parkinson and MS have been tracked to gut microbes.
Not all of the organisms in the human gut have been identified. E Coli is one that has been identified and it is well known. Some species of E Coli are dangerous and cause severe illnesses. On the other hand another species E. Coli Nissle became the active ingredient in a drug used to treat diarrhea.
This is only one example of the many beneficial bacteria in our gut.but we need to be careful. Antibiotics are over prescribed in America. Many of the antibiotics destroy healthy gut organisms as well as pathogens. causing the balance between different organisms to be upset. This in turn could cause other illnesses.
