Until 1984, it was believed that the human stomach was sterile, that no bacteria could survive the stomach acids. I do believe at this time, we had some pretty powerful microscopes, even back in the early 1900's, yet this belief was accepted by many teams of scientists and researchers.
It is now known that not only does H Pylori infect most stomachs, but many other bacteria's as well. Researchers and scientists say that the experiences reported on this forum are not possible. Scientists can be wrong.
