A new study published in PNAS Nexus has found that certain bacteria in the mouth may play a role in the risk of developing Alzheimer’s disease. The research, which analyzed 110 people over 50, discovered that two types of bacteria – Neisseria and Haemophilus – were linked to better memory and attention, while another type, Porphyromonas, was associated with a higher risk of Alzheimer’s.
The study suggests that the bacteria may impact brain health through inflammation in the body. When harmful bacteria enter the bloodstream, they can damage the brain, potentially increasing the risk of Alzheimer’s disease. However, experts caution that it’s difficult to determine if the bacteria causes the disease or if they are simply associated with poor oral health.
To promote good oral and cognitive health, researchers recommend eating a plant-based diet rich in nitrate-rich foods like vegetables. Jennifer Bramen, PhD, suggests that adding these foods to your diet can help suppress bacteria linked to dementia and promote healthier oral microbiome.
While the study’s findings are promising, it’s essential to note that the link between mouth bacteria and Alzheimer’s risk is still being studied, and more research is needed to fully understand the relationship.
