Researchers at the University of California, Los Angeles have linked specific gut bacteria and their chemical byproducts to faster biological brain aging, Science Daily Exercise reported. The study found that individuals with older-looking brains also experienced poorer memory, focus, and mood. [1]

The findings suggest that biological signs of brain aging can appear decades before obvious symptoms become noticeable. According to Science Daily Exercise, this research indicates that the gut could eventually become a key target for preventative interventions against cognitive decline. [1]

Science Daily Exercise reported that the pace of brain aging appears connected to the composition of gut bacteria and the chemical compounds they generate. These biological changes may start long before individuals suffer clear problems with memory or thinking capabilities. [1]
