A new study has claimed that a species of gut bacteria commonly found in stomachs of human beings could have a role in preventing obesity too. Most people have the feeling that all bacteria are bad, but some can also benefit our health in a way is shown by this species, and of course, the claims of this study.
People who yearn for a lean figure would especially love them. They are Helicobacter pylori, also the reason behind most stomach ulcers.
These revelations were made in a rather indirect manner – when scientists tried ways to treat the bacteria, patients gained weight. However, patients who were left untreated for the bacteria lost weight.
H pylori are however a very common species of bacteria found to colonize in human stomachs. It is estimated that around 50% of the world’s population may be infected with it, but only 20% of them experience symptoms.
The study that suggests this inverse correlation between the rate of overweight and obesity and the prevalence of H pylori infection took data from 49 different studies from Japan, US, Australia and ten European countries.
The analysis of all this data led to the conclusion that the gradual decrease of cases of H pylori colonization in the last few decades has also had an impending boom on the cases of obesity in the western world.
The complete study can be found in the journal Alimentary Pharmacology & Therapeutics.
