Bacteriocins: Key to surviving the age of antibiotics?

Defiant Health Radio with Dr. William Davis

About

Normally, you should have numerous species of microbes inhabiting your gastrointestinal tract and other body locations that produce bacteriocins, i.e., natural antibiotics that keep unhealthy microbial species from taking over. Unfortunately, modern antibiotics, while necessary at times, have killed off species that were previously protecting you by producing bacteriocins. This allows the emergence of health problems mostly unique to modern people including weight gain, type 2 diabetes, irritable bowel syndrome, fibromyalgia, depression, anxiety and many others. 

Rebuilding a microbiome that includes species that produce bacteriocins is an important factor in reclaiming control over health disrupted by exposure to modern antibiotics.
