1. Lighter Coffee Roasts Have More Antioxidants
Caffeine may be what keeps people coming back for more coffee, but the beverage also contains chlorogenic acid, a beneficial compound. Both substances are antioxidants, meaning they protect cells from damage caused by free radicals. Korean researchers measured them in coffee beans that had been roasted to different levels: light, medium, city and French (the last two are darker roasts). The amount of caffeine didn’t change much, but the lighter the roast, the more chlorogenic acid was present.
