It was found that certain bacteria is actually linked to an increased risk of Alzheimer's disease.The study was led by the University of Exeter, and also revealed that some bacteria found in your mouth can be associated with having better memory and attention.
But how does this bacteria have an impact on your brain health?One way that researchers found was that harmful bacteria could directly enter the bloodstream, in turn causing potential damage to the brain.
Another option is that an imbalance of beneficial and harmful bacteria could reduce the conversion of nitrite in the body to nitric oxide.
