Gut metabolites linked to preserved brain thickness in older adults

In a 104-person trial sub-study, rising levels of gut-produced urolithins tracked with preserved cortical thickness over two years in 55 older adults…In a 104-person trial sub-study, rising levels of gut-produced urolithins tracked with preserved cortical thickness over two years in 55 older adults eating walnuts.
