Editorial: Dietary polysaccharides and brain health

mycolabadmin

This editorial examines how eating foods rich in polysaccharides, such as grains, fruits, and mushrooms, may help protect brain health and cognitive function as we age. The research suggests these foods work through the gut microbiota, which communicates with the brain via the gut-brain axis. While single fiber sources show modest effects, combining different types of fermentable fibers may be more effective for improving memory and preventing age-related cognitive decline.

Exercise improves depressive-like behavior in adolescent mice by regulating sphingosine and ceramide metabolism through microglial CerS1

mycolabadmin

Regular exercise, especially high-intensity training, can help improve depression symptoms in young people by changing how immune cells in the brain function. The study shows that exercise increases production of a specific enzyme (CerS1) in microglia, which are the brain’s immune cells. This enzyme helps balance certain fatty molecules that reduce brain inflammation, ultimately improving mood and reducing depression-like behaviors. The findings suggest exercise works similarly to antidepressant medications for adolescent depression.
