We could be on the verge of another supplement, something drawn from an easily found food source, capsulized and sold to the masses. What will be in these new capsules? Possibly spent coffee grounds. According to a recent study, the antioxidant concentration within spent coffee grounds is remarkable and could provide yet another way to turn trash into treasure.
Antioxidants are natural compounds that help protect the cells of the body from oxidative stress. They have been tied to everything from cancer prevention to a younger looking complexion.
In the recent study, the researchers who published their findings in the ACS’ Journal of Agricultural and Food Chemistry found that used coffee grounds are notably rich in antioxidants. They found that the highest concentration are within grounds from filter, plunger (French press-type) and espresso machines. The smallest concentrations were found in mocha coffeemakers.
