Cocoa powder is rich in antioxidants, iron, and fiber. Mice with fatty liver disease who supplemented with cocoa had less weight gain, inflammation, fat in their livers, DNA damage, and oxidative stress.

Older adults who spend more time on household chores showed bigger brain volume in the hippocampus, which is a strong predictor of cognitive health.

Just 4 minutes of low‐volume high-intensity interval training improves cardiometabolic health, including improved blood glucose, blood pressure, and cardiac function.

Neural stem cells (NSCs) age more rapidly than the rest of the body. In mice, longer-term NSCs, which continually divide and replicate to maintain a stem cell reserve, have a dwindling population with age.
