Research supported by the National Institutes of Health (NIH) shows that repeated head impacts from contact sports can cause early and lasting changes in the brains of young- to middle-aged athletes.

Could cocoa extract supplements rich in cocoa flavanols reduce inflammation and, in turn, prevent age-related chronic diseases? In a new study from the COcoa Supplement and Multivitamin Outcomes Study (COSMOS), investigators from Mass General Brigham and their colleagues looked at changes in five age-related markers of inflammation among participants who received daily cocoa supplements over several years.
