As we age, the composition of the gut microbiota—the collection of bacteria in our intestines—changes. There is an increase in bacteria that can cause inflammation. At the same time, bacteria that are important for producing substances that keep our tissues healthy decrease. These changes can have adverse effects on our overall health.
Animal research shows that restoring a younger bacterial balance in the gut has a positive effect on health and can even extend lifespan. This can be achieved, for example, by transferring gut bacteria from young to older animals. It demonstrates that gut bacteria play an important role in the ageing process.
The gut microbiota is not separate from the rest of the body. All tissues and organs constantly influence each other, including via the bacteria that live in our guts. This complex interplay helps us to understand why ageing manifests itself in such a broad way and why restoring a healthy bacterial balance is so important.
For people wanting to work towards healthy ageing, this research highlights the importance of a well-functioning gut flora. A balanced gut bacteria composition can contribute to reduced inflammation and better health in later life.
