Alzheimer's Disease and the Microbiome

There are more than ten times as many bacteria and other microorganisms in our bodies as there are human cells. Bacteria, viruses, fungi and other microorganisms reside within the digestive tract, primarily within the intestines, and play a fundamental role in digestive and immune health.

The microorganisms are primarily ‘good bacteria’ and maintain a symbiotic relationship with the host. A balanced diet and active lifestyle can promote and maintain the number of ‘good bacteria’ in the gut. However, these colonies may become compromised by ‘bad bacteria’ leading to an imbalance in the gut flora (“dysbiosis”) that can lead to many health problems ranging from inflammation to colorectal cancer.
