Effect of Dietary Changes
Studies have shown that making changes to your diet can have a significant impact on your microbiome, although the exact mechanisms behind these changes are still not fully understood. Both short-term and long-term alterations to your diet have been found to affect the composition of gut bacteria.
For instance, one study found that just five days of following a different diet led to rapid changes in the microbiome. Additionally, introducing diets that are low in fat and high in fiber, or high in fat and low in fiber, can elicit noticeable changes in as little as 24 hours.
These findings suggest that it is never too late to modify your diet for the better, as even dietary changes made later in life can have beneficial effects on your microbiome.
Neurodegenerative Disorders
Recent studies have indicated a possible link between gut health and neurodegenerative disorders commonly associated with aging. An example of such a disorder is Parkinson’s disease, which involves the build-up of a protein called α-synuclein in the brain. In a particular study, mice were fed fecal samples obtained from Parkinson’s patients. The outcome revealed that these samples resulted in an increase in motor dysfunction, suggesting that the gut microbiome could potentially be a contributing factor to the onset of Parkinson’s disease. This implies that the microbiome might spread from the gut to the nervous system, playing a causative role in the development of the disorder.
